A massive new analysis suggests Americans don’t just differ in what they earn or how long they live - they also differ in how they experience wellness. 



Drawing on more than 325,000 survey responses collected over eight years, researchers found clear regional differences in wellness.



People in the Northeastern and Midwestern regions tend to score higher on “traditional” wellness, which includes <a href="https://www.earth.com/news/fitness-focused-medicine-physical-activity-reduces-chronic-disease-risk/">physical health,</a> finances, and social support.



Many Southern regions, by contrast, rank higher on “existential” wellness, such as purpose, meaning, and a strong sense of community identity. The pattern lines up with centuries-old settlement histories that still shape local norms today.



<h2 class="wp-block-heading" id="h-measuring-wellness-two-ways">Measuring wellness two ways</h2>



The team worked with data from the <a href="https://news.gallup.com/topic/well-being-index.aspx" target="_blank" rel="noreferrer noopener">Gallup-Healthways Well-Being Index</a> spanning 2009–2016 and grouped responses into two broader composites.



“Traditional” wellness bundles tangible aspects of life - physical and <a href="https://www.earth.com/news/mental-health-crisis-half-of-the-worlds-population-will-be-affected-by-age-75/">mental health</a>, financial security, and day-to-day social support. 



“Existential” wellness captures the less tangible side - purpose, personal growth, community belonging, and living in line with one’s values.



Separating the two helps explain why some places thrive on paper (jobs, hospitals, income) yet still report a thinner sense of meaning - or the reverse.



<h2 class="wp-block-heading" id="h-an-old-map-explains-modern-feelings"><a></a>An old map explains modern feelings</h2>



To test whether regional culture matters in wellness, the researchers turned to the American Nations Model. 



This framework divides the U.S. into historical “nations” based on who settled there first. Think Yankeedom, the Deep South, Greater Appalachia, El Norte, and others.



Each region inherited durable folkways about trust, autonomy, community, and authority. Even after accounting for education and income, these cultural footprints predicted distinctive wellness profiles where people live.



The headline split was clear. Northeastern and Midwestern regions, including Yankeedom, leaned higher on traditional wellness. 



Several Southern and frontier-legacy regions - such as the Deep South, Greater Appalachia, El Norte, and parts of the Far West - leaned higher on existential wellness.



In other words, the balance of “health and money” versus “purpose and belonging” shifts in systematic ways across the cultural map.



<h2 class="wp-block-heading" id="h-wellness-differences-stand-out">Wellness differences stand out</h2>



Statistically, the contrasts weren’t subtle. In within-region comparisons, traditional wellness significantly exceeded existential wellness in Yankeedom.



Existential wellness was higher in the Deep South and especially Greater Appalachia - the largest reversal in the set.



Several other regions showed smaller or no gaps, demonstrating that not every place fits a single mold.



These effects held in mixed-effects models that controlled for <a href="https://www.earth.com/news/why-education-matters-for-healthy-aging-and-longevity/">education</a> and income and accounted for clustering within metropolitan areas.

<h2 class="wp-block-heading" id="h-culture-race-and-wellness">Culture, race, and wellness</h2>



The study also looked at Black and Hispanic residents across regions. Patterns generally echoed the broader map. 



Black and Hispanic respondents tended to show higher traditional wellness in Northeastern and Midwestern regions. They also reported higher existential wellness in Southern regions.



Notably, Black respondents showed consistently lower traditional wellness than white respondents across regions. In the Northeast and Midwest, they also fared worse on existential wellness. 



Together, these patterns suggest that material constraints and structural disparities remain powerful drivers.



At the same time, the relatively stronger existential scores in many Southern contexts may reflect the buffering role of community networks and cultural identity.



<h2 class="wp-block-heading" id="h-cultural-roots-of-wellness">Cultural roots of wellness</h2>



Culture shapes where institutions flourish (hospitals, schools, civic groups), how people relate to one another (trust, norms of reciprocity), and what counts as a good life (autonomy vs. solidarity, achievement vs. belonging).



Those long-running preferences influence migration, policy choices, and investments that, over time, help set the table for different “flavors” of well-being.



The authors found the pattern persisted even after adjusting for education and income, and they reported model checks to reduce issues like multicollinearity among predictors.



That suggests the American Nations framework isn’t just a clever historical story - it adds real explanatory power to why wellness feels different in different parts of the country.



<h2 class="wp-block-heading" id="h-wellness-policy-must-fit-culture">Wellness policy must fit culture</h2>



If you want to boost <a href="https://www.earth.com/news/simply-looking-at-art-can-improve-your-well-being/">well-being</a>, focusing only on income or clinics may miss what makes people feel whole in a given place.



In regions that already score high on traditional metrics, investing in community identity, public spaces, and opportunities for contribution might move the needle on meaning and purpose.



In places rich in existential wellness but poorer on traditional metrics, policies that improve access to preventive care, stable work, and safety nets could pay outsized dividends.



Put simply, the study argues that wellness strategies work best when they respect the cultural ecologies where people live - strengthening what’s already strong while shoring up what’s thin.



<h2 class="wp-block-heading" id="h-limits-and-a-next-step"><a></a>Limits - and a next step</h2>



This is an observational study using self-reported survey data; it can’t prove cause and effect. The American Nations borders blur in real life, people move, and city-level differences within regions can be large.



Still, with more than 325,000 respondents across 110 metro areas and eight years of data, the signal is hard to ignore. 



The authors call for digging into mechanisms: Which specific institutions or community practices best translate cultural inheritance into day-to-day well-being? 



And which levers - health infrastructure, schooling, neighborhood design, civic organizations - offer the highest return in each region?



<h2 class="wp-block-heading" id="h-place-and-culture-shape-wellness">Place and culture shape wellness</h2>



Where you live doesn’t just shape your paycheck and your hospital bill. It also shapes how you experience a <a href="https://www.earth.com/news/creativity-improves-life-satisfaction-and-overall-well-being/">good life</a> - whether that’s feeling financially secure and physically well, or feeling rooted in purpose and community.



The United States’ oldest settlement patterns still echo in those experiences today. 



They remind policymakers that the most effective pathways to human flourishing may look different from Boston to Birmingham to El Paso.



The study is published in the journal <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0327972" target="_blank" rel="noreferrer noopener">PLOS One</a>.

Wellness in America depends on culture and where you live

A massive new analysis suggests Americans don’t just differ in what they earn or how long they live - they also differ in how they experience wellness. Drawing on more than 325,000 survey responses collected over eight years, researchers found clear regional differences in wellness. People in the Northeastern and Midwestern regions tend to score higher on “traditional” wellness, which includes physical health, finances, and social support.

If you’re trying to eat a healthy breakfast, put down the <a href="https://www.earth.com/news/avocado-supply-struggling/">avocado toast</a>. Choosing the right food pairings is as important as picking healthy foods when it comes to nutrition.

Writing for the <a href="https://www.dailymail.co.uk/health/article-7063335/Why-food-PAIRINGS-important-Nutritionist-ingredients-enhance-ruin-meals.html">Daily Mail</a>, nutritionist Rob Hobson of <a href="https://www.healthspan.co.uk/">Healthspan</a> broke down how pairing the wrong foods together can negate their health benefits.

“The food pairing choices you make will have a very real effect on your energy, how quickly you feel hungry again after eating – and therefore your weight,” Hobson wrote for the Mail.

For an example, he cited a recent <a href="https://web.iit.edu/">Illinois Institute of Technology</a> study on avocado toast. Avocado can help control blood sugar and suppress hunger on its own, but when eaten with white bread, the carbohydrates in the bread mostly negated those benefits. The study showed that fats like avocado are healthy, and that carbs should be eaten only in moderation – and not in their processed form, Hobson said.

Another example: Beef chili with beans. Beef is high on iron, Hobson noted, but the phytates in beans can bind with that iron and keep it from being absorbed. Adding in plenty of vitamin C-rich vegetables like red bell peppers can boost iron absorption. 

So what are some better food pairings? Hobson offered up several suggestions:
<ul>
 	<li style="font-weight: 400;">Sweet potatoes and Greek yogurt. Sweet potatoes keep blood sugar stable thanks to slowly digested carbs, and Greek yogurt packs protein.</li>
 	<li style="font-weight: 400;">Oats and banana. Oats are a fiber and can keep you feeling full longer. Bananas are a prebiotic and may help control a hormone that makes you hungry. Nut butter and banana make another good pairing.</li>
 	<li style="font-weight: 400;">Smoked salmon and scrambled egg. This “double whammy” of protein and healthy fats (including omega-3 fatty acids) can help you feel full longer. Egg on whole-grain bread is another good option.</li>
 	<li style="font-weight: 400;">Vegetable soup with beans, lentils or peas. The water content in soup can help you fill up faster, and the protein and fiber in legumes can extend that feeling of fullness.</li>
</ul>
Other great food pairings are yogurt topped with dried fruit and nuts, salad with quinoa, or beans and brown rice.

“[Satiety is] particularly important for weight management as it can help to ward of hunger pangs and the temptation to snack between meals,” Hobson wrote. “Therefore, understanding which foods are more satiating and how to put meals together using them will help you to control how much you eat later on in the day.”

New research from <a href="https://www.psu.edu/">Penn State University</a> shows that climate change marches actually have a positive effect on the American public. 

The team found that people who were bystanders at the <a href="http://www.earth.com/news/washington-march-science-earth-day/">March for Science</a> and the People's Climate March in spring 2017 were more optimistic about being able to work together to address climate change issues, and they also had positive feelings toward those who participated in the marches.

"Marches serve two functions: to encourage people to join a movement and to enact change," said Janet Swim, professor of psychology at Penn State. "This study is consistent with the idea that people who participate in marches can gain public support, convince people that change can occur, and also normalize the participants themselves."

"There are several measures that predict people engaging and taking action in the future," Swim continued. "One of those is collective efficacy — the belief that people can work together to enact change. People don't want to do something if it's not going to have an effect. We were interested in whether marches increased this sense of efficacy, that once you see other people do something, you might think yes, it's possible."

Swim and her colleagues recruited 587 bystanders who observed the marches through media, and each bystander was asked to complete a survey asking them about their knowledge of the marches, their thoughts on people who participated in the marches, and their beliefs on whether people can come together to positively affect climate change. They were also asked about their preferred news source (these sources were then coded to be liberal or conservative).

302 of these bystanders completed a survey a day before the March of Science, and 285 completed a survey several days after the People’s Climate March.

"Activists are often seen negatively — that they're arrogant or eccentric or otherwise outside of the norm," Swim said. "There's a fine line between marchers and other activists expressing themselves and raising awareness of their cause, while also not confirming negative stereotypes. So, one of our questions was whether marches increase or decrease people's negative impressions of marchers."

The team found that people surveyed after the People’s Climate March were generally more optimistic about the idea of people coming together to thwart climate change (collective efficacy beliefs). They also had less negative thoughts about the activists involved. And those who consumed more conservative media were more likely to feel the need to get involved in the fight against climate change after the People’s Climate March.

"If conservative news sources only talk [about] the march after the fact, that might be why their viewers have more efficacy afterwards, because they didn't know about it before," Swim said. "Additionally, a more liberal news source may portray marchers as more sympathetic, which may be why their viewers had more favorable impressions of marchers."

Swim hopes to further look into hows news and media influences the public’s view on climate change.

Researchers from the <a href="https://www.isglobal.org/en">Barcelona Institute for Global Health (ISGlobal)</a> have found that boys who are exposed to <a href="http://www.earth.com/news/children-develop-asthma-air-pollution/">air pollution</a> while in the womb may end up having poorer thinking skills and memory than boys who aren’t. 

These findings are published in <a href="https://ehp.niehs.nih.gov/">Environmental Health Perspectives</a>.

The team narrowed their research to analyze the effects of PM2.5, a tiny pollutant emitted by diesel fumes, on schoolchildren. Boys who were exposed to PM2.5 within the womb and up to age 7 performed poorer on memory tests than their peers.

Furthermore, the researchers found that girls who were exposed to PM2.5 while in the womb were not affected the same way, possibly due to their different hormones and genetics. However, both sexes exposed to the pollutant performed poorly on computerized tasks.

“As yet, we don't understand what causes these differences [between boys and girls],” lead researcher Dr. Ioar Rivas told the <a href="https://www.dailymail.co.uk/health/article-7063533/Baby-boys-exposed-toxic-air-womb-worse-thinking-skills.html">Daily Mail</a>. “But there are various hormonal and genetic mechanisms that could lead to girls having a better response to inflammatory processes triggered by fine particulate matter and being less susceptible to the toxicity of these particles.”

The researchers examined data collected from 2,221 schoolchildren, each aged between 7 and 10. Each child’s cognitive ability was tested via several computerized tests, and their pre-birth and childhood exposure to air pollution was also measured by the team.

The results showing that boys’ thinking and memory were affected by PM2.5 throughout childhood suggest that exposure to fine particulate matter over several years has a cumulative effect — an effect that worsens over time.

“This study reinforces our previous findings and confirms that exposure to air pollution at the beginning of life and throughout childhood is a threat to neurodevelopment and an obstacle that prevents children from reaching their full potential,” concluded study author Jordi Sunyer, childhood and environment programme coordinator at ISGlobal.

Previous studies have concluded that every 3.6 years spent in higher education lessens one’s risk for <a href="http://www.earth.com/news/skipping-breakfast-heart-disease/">heart disease</a> by a third. But up until now, scientists weren’t quite sure why that is. 

Now, scientists from <a href="https://www.imperial.ac.uk/">Imperial College London</a>, <a href="http://www.bristol.ac.uk/homepage/">University of Bristol</a>, <a href="https://www.cam.ac.uk/">University of Cambridge</a>, and <a href="http://www.ox.ac.uk/">University of Oxford</a>, have used statistical and genetic analyses to clarify the link between education and heart disease. 

Their new research is published in <a href="https://www.bmj.com/">The BMJ</a>.

"Although we know from previous research that someone who spends more time in education has a lower risk of heart disease and stroke, we didn't know why,” said co-first author Dr. Dipender Gill, from <a href="https://www.imperial.ac.uk/school-public-health">Imperial's School of Public Health</a>. “Surprisingly, our research suggests only half of this protective effect comes from lower weight, blood pressure and less time smoking.”

In fact, the team found that only 40% of the effect on higher education on cardiovascular health can be explained by a person’s body mass index (BMI), blood pressure, or smoking habits.

Furthermore, the study revealed that each 3.6 additional years in education often lowered BMI by 1kg/m2, as well as systolic blood pressure by 3mm/Hg.

“We now need to investigate what other reasons may link education and lower cardiovascular disease risk,” Dr. Gill continued. “One possibility is that people who spend more time in education tend to engage more with healthcare services, and see their doctor sooner with any health complaints."

"Past policies that increase the duration of compulsory education have improved health and such endeavours must continue,” added co-first author Alice Carter, from the University of Bristol. “However, intervening on education is difficult to achieve and requires large amounts of both societal and political change.”

“Our work shows that there are opportunities to intervene, after education is completed, to reduce the potential risk of heart disease,” Carter continued. “By lowering BMI, blood pressure or rates of smoking in individuals who left school at an earlier age, we could reduce their overall risk of heart disease.” 

The team first analyzed data from over 200,000 U.K. residents who had spent a number of years in education. They compared and contrasted the number of years spent in school to each participant’s BMI, blood pressure, smoking habits, and past cardiovascular health issues like heart attack or stroke.

They then used Mendelian randomisation, which involved using genetic information from public databases for over a million people in order to investigate the link between education and cardiovascular disease risk. The team focused in on a minute DNA difference that has been linked to schooling, aiming to link this genetic marker with BMI, blood pressure, and smoking habits.

These methods of analysis revealed that BMI, blood pressure, and smoking contribute to the effect of education — 18%, 27%, and 34% respectively (a combined 40%).

“It is important to note this work looks at the effect of education on a population level risk of heart disease — and leaving school earlier does not necessarily mean an individual will go on to develop heart disease,” Carter explained. And Dr. Gill added that most of the individuals studied are from European descent. The team plans to widen their research to involve other ethnicities.

Palliative care and hospice care provide comfort to patients and aim to improve the quality of life for those suffering from severe and terminal illnesses. Unlike hospice care, palliative care can and should be an active part of a patient’s treatment plan.  

Now, a new study has revealed that the number of people who will need palliative care is set to double in the next forty years.

Due to the severity of illnesses involved and the constant care required, palliative care can strain <a href="https://www.earth.com/news/insurance-prescribing-healthy-food/">health care systems</a> and future demand for palliative care is only expected to increase. 

In the first study of its kind, researchers from <a href="https://www.kcl.ac.uk/">King’s College London</a> modeled future palliative care projections to help strengthen care policies and ensure that communities expected to be most affected by severe illness and suffering are accounted for. 

“Palliative care can relieve suffering for patients and families, and save money for health systems and society,” said Dr. Katherine Sleeman, the lead author of the study. “To direct effective health care planning and policy development, it is essential to understand both the current and future level of palliative care need.”

The study was published in the journal The Lancet Global Health, and the researchers used the  <a href="https://blogs.worldbank.org/opendata/new-country-classifications-income-level-2018-2019">World Bank’s income classification</a> to model estimates for suffering by gender, age, location, and cause of death. 

By 2060, the number of people with serious suffering will increase, and 48 million people will die with health-related suffering each year. 

The majority of people affected will be those from low and middle-income countries, the researchers found. 

“Palliative care and the relief of suffering have been described as some of the most neglected dimensions of global health today,” said Professor Richard Harding Herbert Dunhill, a co-author of the study. “It is estimated that just 14% of the people who need palliative care globally receive it, most of whom are in high-income countries.”

Older adults will face a rapid increase in health-related suffering, primarily due to cancer and dementia. 

The study results call for a dramatic overhaul in palliative care policies to ensure that lower and middle-income populations are not denied access to care. 

“Immediate global action to integrate palliative care into health systems is an ethical and economic imperative,” said Sleeman. “Our findings call for global policies to strengthen health care systems through availability of essential drugs to relieve symptoms, staff training and public education, with a focus on the populations that will experience the fastest rise of suffering and need.”

New research from <a href="https://www.tufts.edu/">Tufts University</a> has linked specific cancers to the lack or excess of certain foods and sugary beverages. The study is one of the first of its kind to investigate the modifiable risk factors for <a href="http://www.earth.com/news/toxic-contaminants-californias-tap-water/">cancer</a> that are associated with food intake among American adults.

According to the study, diet-related factors may account for more than 80,000 new invasive cancer cases that were reported in 2015, which is the equivalent of 5.2 percent of all new cases that year. This estimate is comparable to the cancer risk associated with alcohol of 4 to 6 percent.

Study first author Fang Fang Zhang is a cancer and nutrition researcher at the Friedman School of Nutrition Science and Policy at Tufts University.

“Our findings underscore the opportunity to reduce cancer burden and disparities in the United States by improving food intake,” said Zhang.

The researchers noted that a diet low in whole grains and dairy yet high in processed or red meat was linked to an increased risk of colorectal cancer. Furthermore, high processed meat consumption was linked to stomach cancer risk, while low fruit and vegetable consumption was tied to cancer of the mouth, pharynx, and larynx.

Colorectal cancer had the highest proportion of diet-related cases, with 38.3 percent of all cases in 2015 connected to poor diets. Cancer of the mouth, pharynx, and larynx was the second most frequent cancer linked to food intake.

In the past 15 years, <a href="http://www.earth.com/news/opioid-overdose-deaths-increased-fourfold/">opioid abuse</a> has dramatically increased among adults in the United States. During the same time frame, there has been a steep rise in suicide attempts among young people. A new study led by researchers at the <a href="https://www.uchicago.edu/">University of Chicago</a> has identified a link between these two epidemics.

“Until now, there has been little focus on the association between the increase in opioid use among adults and the risk of suicidal behavior by their children,” said study senior author Dr. Robert D. Gibbons. 

“We theorized such a link was plausible because parental substance abuse is a known risk factor for suicide attempts by their children. In addition, depression and suicide attempts by parents - which are known to be related to suicidal behavior in their offspring - are more common among adults who abuse opioids.”

The investigation was focused on data from 2010 to 2016 involving more than 240,000 parents between the ages of 30 and 50 years old. Half of the subjects had filled opioid prescriptions for at least 365 days, and the other half had no history of using the drug during that time. 

For the same six-year period, suicide attempts were examined among the participants’ 330,000 children between the ages of 10 and 19. The study revealed that opioid use by a parent is associated with double the risk of suicide attempts by their children.

“These findings demonstrate that opioid use by a parent or parents doubles the risk for suicidal behavior by their children,” said study co-author Dr. David A. Brent. “The epidemics of adult opiate abuse and child suicidal behavior appear to be linked, and the disturbing upward trends in mortality due to opiates and due to child suicide may have common roots.”

The researchers are calling for improved diagnosis and treatment of parents who use opioids as well as mental health screening for their children. “These actions could help reverse the upward trend in deaths due to the twin epidemics of suicide and opioid overdose,” said Dr. Gibbons.

The study is published in the journal <a href="https://jamanetwork.com/journals/jamapsychiatry">JAMA Psychiatry</a>.

Women who suffer a cardiac arrest in their homes or outside of a hospital are less likely to be resuscitated successfully or <a href="https://www.earth.com/news/ambulance-times-low-income-areas/">receive care in time</a>, according to a new study. 

Researchers from the <a href="https://www.uva.nl/en">University of Amsterdam</a> compared the treatment of men and women who suffered cardiac arrests in The Netherlands and found that it took longer for bystanders to call emergency services, attempt to resuscitate, and even recognize that a cardiac arrest had occurred in women compared to men. 

The findings were published in the European Heart Journal. 

When cardiac arrest occurs, the heart starts beating irregularly and fast (more than 300 beats per minute) which prevents blood flow. If caught in time, an electrocardiogram machine can detect the shockable initial rhythm before the heart stops pumping altogether, which leads to death. 

A defibrillator can shock the heart back to a normal rhythm, but only if there is a detectable initial rhythm. If the heart stops pumping the only option is chest compressions. 

Early detection and treatment are key, but the researchers found the majority of women who receive treatment for cardiac arrests have passed that initial shockable rhythm point, leading to more deaths among women. 

“We found that the worse outcome in women is largely attributable to the fact that women had about half the chance of having a shockable initial rhythm compared to men,” said Dr. Hanno Tan, the leader of the research.

For the study, the researchers reviewed and analyzed data from cardiac arrests and resuscitation attempts by emergency services in one province in The Netherlands from 2006 through 2012. 

5,717 of the reported cardiac arrests in that time occurred out-of-hospital and 28 percent involved female patients. 

Bystanders were less likely to attempt to resuscitate a woman who had collapsed, and women had a lower chance of survival after admission to a hospital. Female patients were also less likely to have a detectable initial shock rhythm by the time help arrived or being admitted to the hospital. 

The researchers found that women were half as likely to survive and be discharged from the hospital compared to men. Even correct diagnoses and treatment took longer for women compared to men. 

“Even when we adjusted our results to take account of pre-existing diseases and factors relating to the way in which resuscitation was provided by professionals, for example how long it took for the ambulance to arrive or time to defibrillation after cardiac arrest, we still found that women were half as likely as men to have shockable initial rhythm,” said Dr Tan. 

There are several reasons for why few women in the study had a shockable initial rhythm, and the researchers suggest that it could be that older women at risk of cardiac arrest are more likely to live alone or suffer an attack out of sight. 

Women also have different symptoms compared to men, which can make identifying the problem for what it is right away challenging. 

“People may be less aware that cardiac arrest can occur as often in women as in men, and the women themselves may not recognize the urgency of their symptoms,” said Dr. Tan. “Women may have symptoms of an impending heart attack that are less easy to interpret, such as fatigue, fainting, vomiting and neck or jaw pain, whereas men are more likely to report typical complaints such as chest pain.”

Raising awareness of these issues and differences is important and the researchers say it could be a life and death difference for a person suffering cardiac arrest outside of the hospital. 

“Given the short window available to save the life of the patient, every minute in this early phase counts; help, if only a call to the emergency number by a lay person, is crucial,” said Dr. Tan. “So, raising awareness through public campaigns could make a big impact on women’s survival. The fact that in-hospital treatment also seems to be different is a finding that can be acted on now and may be easier to implement.”

Researchers from the <a href="https://www.unige.ch/en/university/">University of Geneva</a> (UNIGE) have conducted Switzerland’s first reproductive health study among men between the ages of 18 and 22. The nationwide assessment of semen quality revealed that only 38 percent of the men had semen parameter values above the standards that have been established for fertile men by the World Health Organization (WHO).

“We need to be cautious about a single semen analysis,” said study co-author Dr. Alfred Senn. “It isn't entirely predictive of a person's fertility. But, in overall terms, the results suggest that the sperm quality of young men in Switzerland is in a critical state and that their future fertility will in all likelihood be affected.”

The investigation was focused on three important parameters including the number of spermatozoa, their motility, and their morphology. The findings are particularly concerning because <a href="http://www.earth.com/news/competing-mate-sperm-quality/">poor semen quality</a> has been linked to an increase in the incidence of testicular cancer in Switzerland.  

“For 35 years, testicular cancer has grown steadily to over 10 cases per 100,000 men, which is very high compared to other European countries. Sperm quality is generally lower in countries where the incidence of testicular cancer is high,” explained Professor Serge Nef. 

From 2002 to 2010, the number of Swiss couples seeking assisted reproductive technology (ART) doubled from 3,000 to more than 6,000 per year. There are many different causes of infertility in both men and women, including lifestyle factors such as alcohol and tobacco use. 

Over the past few decades, researchers have found a significant decline in semen quality across developed countries, with a notable decrease in the sperm concentration from 99 million per milliliter to 47 million per milliliter. 

“It's important to understand that the time needed to conceive increases significantly if a man has a sperm concentration below 40 million sperm per ml,” said Professor Nef. 

The UNIGE analysis was focused on the semen quality of more than 2,500 young males. The researchers found that 17 percent of the men had a sperm concentration below 15 million per milliliter and 25 percent had less than 40 percent motile spermatozoa in their ejaculate. Among nearly half of the subjects, the rate of morphologically normal forms was below four percent. 

Overall, at least one of the three parameters was below the WHO thresholds for 60 percent of the men, and five percent had a problem concerning all three factors. The UNIGE tean is now assessing the impact of environmental or lifestyle factors to find what is driving lower semen quality in Switzerland. 

“We would also like to go back to the 2,523 men who took part in the study in about 10 years so we can follow up their reproductive health and find out whether they have had children or have suffered from testicular cancer, for example,” said study first author Rita Rahban. 

"With the current trend for couples to have children later in life, the low sperm count among young men in Switzerland - combined with the declining fertility of older women - will have an impact on conception rates and future generations. This will lead to significant social and financial challenges for our society,” concluded Dr. Senn.

The study is published in the journal <a href="https://onlinelibrary.wiley.com/journal/20472927">Andrology</a>.

Spending more time in nature as a kid can lead to better mental health. Growing up with access to sprawling fields, parks, lakes, and forests could lead to better mental health as an adult and an appreciation for green spaces, according to new research. 

Many studies have shown that spending time outdoors in nature has many <a href="https://www.earth.com/news/study-spending-time-in-nature-is-good-for-your-health/">physical and mental health benefits</a>, but researchers from the <a href="https://www.isglobal.org/en">Barcelona Institute for Global Health</a> (ISGlobal) wanted to examine how these benefits are influenced by time spent in natural spaces during childhood. 

The researchers were also looking to expand their assessment to include both green and blue spaces like ponds, rivers, and lakes, areas that other similar studies often overlook. 

Data from the<a href="http://www.phenotype.eu/en/"> PHENOTYPE project</a>, which included information on nearly 3,600 adults from Spain, the Netherlands, Lithuania, and the United Kingdom, were analyzed for the recent study. 

Participants in the PHENOTYPE project were given questionnaires on how often they spent time in natural spaces during childhood and how many purposeful visits and non-purposeful visits to nature they remembered. 

Purposeful visits were defined as going hiking in parks or forests while non-purposeful visits included playing in the backyard. 

The researchers also reviewed surveys on the current use of and satisfaction with natural spaces.  

Mental health was assessed with psychological tests, and the researchers compared participant data to satellite images to see how much residential greenspace participants were in current contact with. 

The results of the analysis, published in the International Journal of Environment Research and Public Health, showed that the participants who reported spending more time outdoors in natural spaces scored higher on the mental health tests and had a greater affinity for green and blue spaces as adults. 

The participants who spent less time in nature during childhood placed less importance and value on green or blue spaces. 

The results of the study highlight the vital role natural spaces plays in mental health and well-being. As people spend more time indoors, not only are we limiting exposure to green spaces, but they lose value and importance among communities who have little access to natural areas. 

“Therefore, it is important to recognize the implications of growing up in environments with limited opportunities for exposure to nature,” said Wilma Zijlema, ISGlobal researcher and the study coordinator

Thousands of <a href="https://www.earth.com/news/more-deaths-air-pollution/">deaths attributable to air pollution</a> may fall under the radar due to a proposed new method of analyzing air pollution health risks by the <a href="https://www.epa.gov/">Environmental Protection Agency (EPA)</a>.

If the EPA does change its calculations, it will provide little incentive for energy companies to shift from fossil fuels, making it even easier for the Trump Administration to rollback Obama-era clean energy regulations. 

The new modeling system could predict fewer deaths, which could lead to a false assumption that current or increased levels of pollution are safer than they actually are, according to a new report from the <a href="https://www.nytimes.com/2019/05/20/climate/epa-air-pollution-deaths.html?smid=nytcore-ios-share">New York Times</a>. 

In reality, air pollution and fine particulate matter especially increase the risk of cardiovascular disease, lower quality of life, and cause millions of premature deaths worldwide. 

The EPA will likely announce the new analysis method as part of the Affordable Clean Energy Rule, which will replace the Clean Power Plan in June. 

It’s a decision that could cost more lives and place a higher burden on health care as the new plan would allow old coal plants to continue operating, emitting more pollution in the process. 

“Particulate matter is extremely harmful, and it leads to a large number of premature deaths,” Richard L. Revesz, an expert in environmental law at New York University, told the New York Times. “It could be an enormously significant impact,” Mr. Revesz said.

In reality, there are no safe levels of air pollution, and the Clean Power Plan aimed to get energy companies to shift to renewables and natural gas, reducing fossil fuel use and particulate matter pollution. 

Those critical of the Clean Power Plan argue that if air levels are “safe” as deemed by EPA guidelines, why should energy companies and businesses invest in costly alternative energy sources. 

For example, it’s been estimated that reducing particulate matter pollution could generate $30 to $40 billion. 

“How in the world can you get $30 or $40 billion of benefit to public health when most of that is attributable to reductions in areas that already meet a health-based standard,” William L. Wehrum, the EPA air quality chief, told the New York Times. “That doesn’t make any sense.”

Those generated benefits would come from reduced health care costs. 

It’s important to remember that just because air particulate matter levels are set at PM 2.5 per year, it doesn’t mean that people exposed to these levels are safe from health risks. 

The EPA and the current Administration could instead be working with bipartisan researchers and policymakers to find the best possible air quality standards that lower health risks and allow for economic progress. But with this new analysis, it seems like just another way to bypass scientific studies and data in favor of easy earnings.

Chemicals in everyday products may be increasing the risk of obesity. According to a new study from the <a href="http://www.uns.ac.rs/index.php/en/">University of Novi Sad</a> in Serbia, exposure to common chemicals called phthalates may contribute to the development of metabolic disorders. The researchers have discovered a link between levels of phthalate exposure and markers of impaired liver function, which indicate an increased risk of <a href="http://www.earth.com/news/obesity-rising-rural-areas/">obesity</a>, diabetes, and heart disease. 

Phthalates are additives that are often used in the production of plastics, with detectable traces found in everyday items including milk, bottled water, instant coffee, perfume, toys, shampoo, and food packaging. Chemicals in everyday products may be increasing the risk of obesity 

Previous studies have found that endocrine-disrupting chemicals can cause an increased risk of obesity, as well as serious damage to fertility and development. The current study is the first of its kind to investigate how phthalate exposure affects obesity and metabolism.

A team led by Professor Milica Medic-Stojanoska compared the levels of phthalate absorbed by people with their body weight, type 2 diabetes incidence, and markers of impaired liver and metabolic function. 

The study revealed that higher exposure to phthalates was associated with increased markers of liver damage, insulin resistance, and cholesterol in people with obesity and diabetes. The research indicates that more action is needed to reduce the public's exposure to these potentially harmful chemicals.

“Although a small association study, these findings suggest that not only do phthalates alter metabolism to increase the risk of obesity and diabetes but that they are also causing toxic damage to the liver,” said Professor Medic-Stojanoska.

“We need to inform people about the potential adverse effects of endocrine disruptors on their health and look at ways to minimise our contact with these harmful chemicals.”

The research will be presented at the <a href="https://www.ese-hormones.org/">European Society of Endocrinology</a> annual meeting, ECE 2019.

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.



"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.



<h2 class="wp-block-heading" id="h-implications-for-astrobiology">Implications for astrobiology</h2>



The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.



The research, published in <a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.

On the unforgiving landscape of North Greenland, temperatures drop and sunlight barely penetrates through the polar winter. It was here, however, that an international team of scientists found <a href="https://www.earth.com/news/predatory-worms-were-terror-beasts-half-a-billion-years-ago/#google_vignette" target="_blank" rel="noreferrer noopener">evidence of sea monsters</a> that would change our understanding of ocean life in the past.



This video captures the discovery of Timorebestia fossils that had been hidden for more than 500 million years in the Sirius Passet formation. The "terror beasts," as they are called, are a hidden chapter in the evolutionary history of <a href="https://www.earth.com" target="_blank" rel="noreferrer noopener">Earth</a>, showing that sophisticated predator-prey interactions occurred much earlier than previously envisioned.



Dr. Jakob Vinther and his research team at the <a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>, in collaboration with researchers at the <a href="https://eng.kopri.re.kr/" target="_blank" rel="noreferrer noopener">Korean Polar Research Institute</a>, braved extreme weather conditions at 82.5 north latitude to locate these giant creatures. Using sophisticated electron microprobe analysis, they revealed the detailed anatomy of the animals, including their muscle and nerve tissues.



The find upsets the traditional timeline of sea predators. Although we've long appreciated that Cambrian oceans were at one time ruled by <a href="https://www.youtube.com/watch?v=jWI3-UgA3_o&amp;list=PL1QLQMW9MWDwpkFOnvgAmu7wT6rZmYqdJ&amp;index=19" target="_blank" rel="noreferrer noopener">arthropods</a>, these discoveries indicate that relatives of arrow worms were first to dominate the seas. These worms were building sophisticated food webs several million years before other predator groups arose.



Each fossil is a story of ancient hunger, with fossil stomach contents revealing these meter-long beasts dined on heavily armored arthropods regularly, cementing their place as the ocean's first apex predators.

<h2 class="wp-block-heading" id="h-385-million-year-old-trees-discovered">385-million-year-old trees discovered</h2>



Scientists have uncovered something extraordinary just two hours north of New York City. The <a href="https://www.earth.com/news/worlds-oldest-forest-discovered-close-to-new-york-city/" target="_blank" rel="noreferrer noopener">world's oldest forest</a>, dating back 385 million years, offers a window into how Earth's first complex forests shaped our planet's atmosphere.



Located near <a href="https://townofcairo.com/" target="_blank" rel="noreferrer noopener">Cairo, New York</a>, in Greene County, these weren't merely primitive plants struggling to survive. These were sophisticated trees with root systems remarkably similar to modern forests. This ancient woodland predates dinosaurs by 140 million years.



<h2 class="wp-block-heading" id="h-the-cairo-forest-discovery">The Cairo forest discovery</h2>



385 million years ago, upstate New York was a tropical paradise near the equator. Thanks to continental drift, this ancient forest has traveled thousands of miles to its current location.



The fossil forest sits in an abandoned quarry, roughly half the size of a football field. This represents just a slice of what was likely a massive forest system stretching from New York into Pennsylvania.



Charles Ver Straeten, curator of sedimentary rocks at the <a href="https://www.nysm.nysed.gov/" target="_blank" rel="noreferrer noopener">New York State Museum</a>, made the discovery in 2009. While scouting the former highway department property, his trained eye spotted wandering patterns in the stone that looked like marine features.



<h2 class="wp-block-heading" id="h-revolutionary-age-and-preservation">Revolutionary age and preservation</h2>



The site contains 385-million-year-old rocks with fossilized woody roots forming horizontal patterns up to 18 feet (5.5 meters) wide. As Christopher Berry, a paleobotanist at Cardiff University, explains: "You are walking through the roots of ancient trees."



This discovery pushes back advanced tree evolution by millions of years. The research, published in <a href="https://www.cell.com/current-biology/home" target="_blank" rel="noreferrer noopener">Current Biology</a> in December 2019, fundamentally changes our understanding of when complex forests first emerged.



Researchers believe a massive flood buried the forest floor, creating perfect fossilization conditions. Over millions of years, sediment hardened into rock, preserving these root patterns like nature's time capsule.



<h2 class="wp-block-heading" id="h-meet-archaeopteris-the-first-modern-tree">Meet Archaeopteris: the first modern tree</h2>



The star of this ancient forest is Archaeopteris – not to be confused with the feathered dinosaur Archaeopteryx. This tree was far older and more revolutionary.



William Stein from <a href="https://www.binghamton.edu/" target="_blank" rel="noreferrer noopener">Binghamton University</a> describes the roots as "strikingly modern, essentially what you'd see outside in my yard right now." These weren't simple root systems you'd expect from ancient plants.



Some fossilized roots are six inches (15 centimeters) in diameter, forming 36-foot-wide (11-meter) patterns. These giants grew up to 65 feet (20 meters) tall with five-foot-diameter (1.5-meter) trunks.



<h2 class="wp-block-heading" id="h-climate-changing-impact">Climate-changing impact</h2>



These trees fundamentally changed Earth's environment. Kevin Boyce, a Stanford University geoscientist, explains how their deep roots triggered "weathering," chemical reactions that pulled carbon dioxide from the atmosphere.



This process dropped atmospheric CO2 levels from 10-15 times higher than today to roughly modern concentrations. These ancient trees helped create atmospheric conditions that made complex life possible.



<h2 class="wp-block-heading" id="h-ancient-forest-ecosystem">Ancient forest ecosystem</h2>



The forest was remarkably diverse. Scientists identified Eospermatopteris, palm tree-like plants with short roots that reached 30 feet (9 meters) tall but lacked woody structure. The forest also housed cladoxylopsids and a mysterious third species still being studied.



All reproduced through spores rather than seeds – millions of years before seeds evolved. This tropical environment had no grass, flowers, or flying insects, just towering trees creating Earth's first complex forest canopy.



<h2 class="wp-block-heading" id="h-scientific-significance">Scientific significance</h2>



Before this finding, the Gilboa forest, located 25 miles (40 kilometers) away, held the "oldest forest" title. Cairo's trees are 2-3 million years older, showing that complex forest ecosystems developed much faster than scientists believed possible.



Patricia Gensel, a <a href="https://www.unc.edu/" target="_blank" rel="noreferrer noopener">University of North Carolina</a> paleobotanist, notes: "The size of those root systems is really changing the picture. Even 20 years ago, researchers assumed trees with such complex root systems didn't evolve so early."



The Cairo site presents three unique root systems, suggesting Devonian period forests were diverse ecosystems with different trees occupying different environmental niches, much like today's forests.



<h2 class="wp-block-heading" id="h-modern-preservation-efforts">Modern preservation efforts</h2>



In 2022, New York State Senator Michelle Hinchey secured a $170,000 grant for the town of Cairo to construct specialized fencing around the fossil forest site. The town plans to conduct a feasibility study exploring the possibility of creating an educational center and working lab on-site.



Joe Hasenkopf, chair of the Cairo Planning Board, hopes to partner with educational institutions to create a research facility serving scientists, students, and the public.



<h2 class="wp-block-heading" id="h-lessons-for-today-s-climate">Lessons for today's climate</h2>



Why does a 385-million-year-old forest matter today? It shows how dramatically forests can change Earth's climate. These ancient woodlands created the atmospheric conditions supporting complex life.



Understanding how prehistoric forests transformed the planet helps us appreciate modern forests' critical role in addressing climate change. Forests remain Earth's most effective carbon capture systems.



These prehistoric trees changed Earth's atmosphere by pulling massive amounts of carbon dioxide from the air. As we face modern climate challenges, this ancient forest reminds us of trees' incredible power to transform our planet's environment.



The next time you walk through a forest, remember you're experiencing an ecosystem whose blueprint was established 385 million years ago in upstate New York. These ancient pioneers didn't just survive – they thrived and changed the world forever.



The full study was published in the journal Current Biology.

</div><figcaption class="wp-element-caption">Acid rain and a crisis solved.</figcaption></figure>



<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

Mid-July is an opportune time to kick-start a thriving fall garden, and this guide lays out the best vegetables and herbs to plant now for a fruitful autumn harvest. 



Fast-growing leafy greens such as spinach, lettuce, kale, and arugula perform especially well in the waning summer heat, with harvests beginning as soon as 30 days. 



These cool-season crops relish the transition into fall, offering repeated yields with cut-and-come-again methods.



Root vegetables like radishes, carrots, and beets also excel during this period. Radishes deliver satisfaction in under a month, while carrots and beets mature in about two months. Employing succession planting ensures a continuous stream of produce deep into the cooler months. 



For a boost of fresh flavor, herbs like cilantro, basil, dill, and chervil are excellent picks. These heat-loving varieties flourish in July’s warmth and are harvest-ready in about 30 days, especially when sown continuously.



Gardeners in zones 6 through 9 can benefit from planting bush beans and snap peas, which don’t require trellising and are ideal for compact plots. 



Maturing in 50–60 days, they’re a smart choice for quick, protein-rich harvests. For those in hotter regions, heat-tolerant crops such as okra and southern peas provide reliable yields and thrive in scorching conditions.



This guide emphasizes more than crop selection—it highlights the importance of timing, soil preparation, and ongoing sowing techniques. 



With thoughtful planning and attention to regional climate needs, even late-summer gardeners can enjoy fresh salads, hearty stews, and the satisfaction of a robust, homegrown harvest well into fall.

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

Wildlife tunnels save millions of amphibians

https://youtu.be/XYgiPzmNBTU?si=eFYY7gPHU1JznLvU A new long-term study in Monkton, Vermont, reveals that...

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."
