A growing collection of studies has shown that global warming entails more than just higher temperatures. Extreme <a href="https://www.earth.com/news/how-does-extreme-weather-impact-marine-ecosystems/">weather</a> events are occurring more often and are becoming increasingly powerful in many parts of the world, necessitating an urgent need to forecast and prepare for them.



The results of a new modeling study led by the <a href="https://www.tsukuba.ac.jp/en/">University of Tsukuba</a> predict that "atmospheric rivers" will cause more frequent and severe extreme downpour events across East Asia.&nbsp;



Atmospheric rivers are long, narrow regions of concentrated water vapor moving across the atmosphere. When one of these bands collides with a barrier, such as a mountain range, it can result in significant rainfall or snowfall.



Parts of East Asia have been regularly subjected to this weather phenomenon over the last decade, sometimes at a great social cost. It is critical to understand how atmospheric rivers will evolve in the future as the climate continues to change.



“To investigate the behavior of atmospheric rivers and extreme precipitation over East Asia under projected climate warming, we used high-resolution global atmospheric circulation model simulations as well as regional climate model downscaling simulations," said study first author Professor Yoichi Kamae.



"We compared simulations based on historical meteorological data from 1951 to 2010 with future simulations based on the year 2090 under a climate scenario with 4 degrees Celsius of warming of the global-mean surface air temperature.”&nbsp;



Future simulations anticipated enhanced water vapor movement and precipitation, including extraordinary, record-breaking rainfall events in regions of East Asia, all of which would be influenced by atmospheric river phenomena.



The southern and western slopes of mountains in East Asia, including Japan, the Korean Peninsula, Taiwan, and northeastern China, received the most atmospheric river-related rainfall, with the southwestern slopes of the Japanese Alps receiving the most rainfall.



The geographical scope of this study was limited to East Asia due to technical restrictions in combining the models.



“Our findings are likely also applicable to other regions of the mid-latitudes where interactions between atmospheric rivers and steep mountains play a major role in precipitation, such as in western North America and Europe. These regions may also experience more frequent and intense extreme precipitation events as the climate warms.” explained Professor Kamae.



The Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan supported this research with JSPS KAKENHI Grants and the Integrated Research Program for Advancing Climate Models.



The study is published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/journal/19448007">Geophysical Research Letters</a>.

The Omicron variant is spreading all over the world at an alarming rate, reaching even the world’s most <a href="https://www.nytimes.com/live/2022/01/21/world/omicron-covid-vaccine-tests/omicron-extends-its-reach-to-some-of-the-planets-most-remote-islands">remote islands</a> – many of which managed to stay protected from the <a href="https://www.earth.com/news/llama-antibodies-have-potential-to-treat-coronavirus-variants/">coronavirus</a> for over two years before this highly contagious strain hit.&nbsp;



However, the situation in several countries, including previous epicenters such as South Africa and the United Kingdom, suggests that the Omicron waves are much shorter and less damaging than the Delta ones, with case numbers rising rapidly to unprecedented highs and afterwards steeply declining, and hospitalizations and deaths remaining relatively low. Currently, the United States also appears to have reached its Omicron peak, and is now embarking on its downward slope.&nbsp;



Sadly, hospitalization and death rates in the U.S. remain disproportionately high, compared to those in more vaccinated countries such as the UK, Spain, or Portugal. Three new studies led by the <a href="https://www.cdc.gov/">Center for Disease Control and Prevention</a> (CDC) and published on Friday, January 22, 2022 have highlighted the importance of mRNA (Pfizer BioNtech and Moderna) booster shots for preventing severe Omicron illness. These are the most comprehensive and reliable assessments to date of the role boosters played in United States’ Omicron wave.



In <a href="https://www.cdc.gov/mmwr/volumes/71/wr/mm7104e3.htm?s_cid=mm7104e3_w">one study</a>, scientists investigated hospitalizations and emergency room visits from August 26, 2021 to January 5, 2022, and found that vaccine effectiveness against hospitalization with Omicron fell to 57 percent for people with two doses of mRNA vaccines, but that a third shot restored the protection to 90 percent.&nbsp;



A <a href="https://www.cdc.gov/mmwr/volumes/71/wr/mm7104e2.htm?s_cid=mm7104e2_w">second study</a> analyzed nearly ten million Covid cases and over 117,000 associated deaths and found that booster shots reduced significantly the number of both symptomatic infections and deaths caused by Covid-19, particularly among people aged 50 and older.



Finally, a third study published in the journal <a href="https://jamanetwork.com/journals/jama/fullarticle/2788485">JAMA</a> has compared the effectiveness of booster shots against symptomatic infection with Delta, respectively Omicron, in over 70,000 people. While boosters are indeed less protective against symptomatic infection with Omicron than with Delta, they are still providing a much higher level of protection than vaccination with only two doses.



“The data here show the protection provided by vaccines and the importance of being up to date on your Covid-19 vaccination, which for tens of millions of Americans means getting a booster dose,” said CDC Director Rochelle Walensky.&nbsp;



“A booster is essential for preventing severe disease, hospitalization, and deaths,” added Eric Topol, a professor of Molecular Medicine at <a href="https://www.scripps.edu/">Scripps Research</a>. According to him, public health officials need to communicate clearly that, although the vaccines and booster shots are “not holding up against Omicron infections, they are holding up the wall against severe disease … and that’s phenomenal.”



Further research is needed to assess the usefulness of boosters in younger and healthier individuals. In the meanwhile, the need to initiate the vaccination scheme for a very large number of people in the United States and abroad remains crucial for avoiding future Covid-19 waves and the emergence of new - and possibly more deadly - coronavirus variants.&nbsp;&nbsp;&nbsp;

Diplodocus,Dinosaur,Scene,From,The,Jurassic,Era,3d,Illustration

A team of researchers from the <a href="https://www.bristol.ac.uk/">University of Bristol</a> has recently reconstructed the limb musculature of Thecodontosaurus&nbsp;antiquus, a wolf-sized Triassic-period <a href="https://www.earth.com/news/new-dinosaur-species-discovered-in-brazil/">dinosaur</a> considered to be an early ancestor of the iconic long-necked, quadruped Diplodocus, and found that this magnificent creature ran on its two back legs and used its shorter forelimbs to grasp food.



“The University of Bristol houses a huge collection of beautifully preserved Thecodontosaurus fossils that were discovered around Bristol,” said study lead author Antonio Ballell, a paleobiologist at this university.&nbsp;



“The amazing thing about these fossilized bones is that many preserve the scars and rugosities that the limb musculature left on them with its attachment.” If they are well-preserved, these features - in tandem with an understanding of the musculature of closely-related, modern animal species - can be used to infer the shape and direction of dinosaur limb muscles, and shed more light on the way such dinosaurs looked and moved.&nbsp;



“In the case of dinosaurs, we have to look at modern crocodilians and birds, that form a group that we call archosaurs, meaning 'ruling reptiles.'&nbsp;Dinosaurs are extinct members of this lineage,” said Dr. Ballell. “Due to evolutionary resemblance, we can compare the muscle anatomy in crocodiles and birds and study the scars that they leave on bones to identify and reconstruct the position of those muscles in dinosaurs.”



By employing this methodology, Dr. Ballell and his colleagues inferred the orientation and size of Thecodontosaurus' limb muscles, and found that this dinosaur was able to run quite fast on its hind legs and likely used its forelimbs not to walk but rather to grasp various objects, such as food items.&nbsp;



These features are surprisingly different from Thecodontosaurus' giant sauropod relatives such as Diplodocus, who were slow, massive quadrupeds. However, according to the scientists, the muscular anatomy of Thecodontosaurus did show signs of having developed many of the structural features which will allow its descendants to switch to quadrupedalism and reach such colossal dimensions.



“From an evolutionary perspective, our study adds more pieces to the puzzle of how locomotion and posture changed during the evolution of dinosaurs and in the line to the giant sauropods,” said study senior author Michael Benton, a paleontologist at the University of Bristol.



A better understanding the anatomy of dinosaurs such as Thecodontosaurus will likely help scientists clarify how limb muscles modified in the evolution of multi-ton quadrupeds from tiny bipeds. “Reconstructing the limb muscles of Thecodontosaurus gives us new information of the early stages of that important evolutionary transition,” concluded Professor Benton.



The study is published in the journal <a href="https://royalsocietypublishing.org/doi/10.1098/rsos.211356">Royal Society Open Science</a>.

A team of researchers from the University of Bristol has...

A new study led by the <a href="https://www.ox.ac.uk/">University of Oxford</a> has found that black-browed albatrosses (Thalassarche melanophris) can dive up to 62 feet (19 meters) into the sea in pursuit of their <a href="https://www.earth.com/news/killer-whales-are-not-short-of-prey-in-southwestern-canada/">prey</a>, and can stay under water for up to 52 seconds – three times the maxima previously recorded for this species.



“Albatrosses are the iconic aerial wanderers of the oceans, supremely adapted for long-distance dynamic soaring flight. Perhaps because of this they are considered poorly adapted for diving in contrast to many smaller shearwater and petrel relatives, despite having amphibious eyes, and an&nbsp;a priori&nbsp;mass advantage for oxygen-storage tolerance,” wrote the study authors.&nbsp;



“Modern biologging studies have largely confirmed this view,&nbsp;casting doubt on earlier observations using capillary tube maximum depth gauges, which may exaggerate depths, and emphasizing albatrosses’ reliance on near-surface feeding.”



By using accelerometers, depth sensors, and GPS technology, the researchers studied the diving behavior of the albatross population of New Island (one of the Falkland Islands), and found that they can reach much more impressive depths in pursuit of prey than previously estimated.



Clarifying these issues is highly important for the conservation of these magnificent seabirds. According to the scientists, 15 of the 22 albatross species are currently at risk of extinction. One of the key drivers of their decline is <a href="https://www.earth.com/news/lighted-nets-help-protect-endangered-marine-wildlife/">accidental catch</a> in the hooked, baited fishing longlines used by commercial fisheries to trap large oceanic species such as tuna.&nbsp;



Since albatrosses were previously considered to be surface feeders, traditional approaches to protect them have only paid attention to the initial sinking of the fishing lines, without taking into consideration their possible bycatch during their deep dives.



“A better understanding of the unobserved behavior of the albatross and other endangered seabirds is essential to conservation efforts,” said study co-author Dr.&nbsp;Oliver Padget, a zoologist at the University of Oxford. “That black-browed albatrosses are physically capable of such deep dives will now need to be considered when thinking about the effectiveness of mitigation strategies that rely on the species being restricted to the surface.”



Moreover, the scientists noticed that black-browed albatrosses did not dive at night, suggesting that they rely on vision to track shoals of fish in the depths of the sea. “We found that deep diving was restricted to daylight hours,” said Dr. Padget. “So one potential mitigation could be for pelagic long lines to be set at night when albatross might be less likely, or able, to chase baits and become caught.”



The study is published in the journal <a href="https://doi.org/10.1016/j.cub.2021.11.036">Current Biology</a>.

A new study led by the University of Oxford has...

According to a new study led by <a href="https://www.stanford.edu/">Stanford University</a> and published in the journal Cell, male and female mouse <a href="https://www.earth.com/news/social-isolation-damages-our-brains/">brains</a> differ significantly. By probing four tiny structures within mouse brains that are known to be responsible for the so-called “rating, dating, mating, and hating” behaviors, the scientists found over 1,000 genes with different activity levels in the brains of one sex versus the other. Although this study focused on mice, the sex differences are likely to occur in the brains of humans too.



The genetic makeup of the brain most probably accounts for much of the sex-typical social behaviors, which have been built into animals’ brains over millions of years of evolution.&nbsp;



Male mice, for example, are able to quickly determine the sex of strangers intruding on their territory. The mice attack the strangers if they are male, or start courting them if they are female.&nbsp;



By contrast, female mice exhibit maternal rather than territorial aggression, and are much more genetically inclined to protect their pups than males. Moreover, their willingness to mate is strongly related to the stage of their estrous cycle.



“These primal behaviors are essential to survival and reproduction, and they’re largely instinctive,” and determined by the differential activation of various genes, explained study senior author Nirao Shah, a professor of Psychiatry, Behavioral Sciences, and Neurobiology at Stanford. “Using these&nbsp;genes as entry&nbsp;points, we’ve identified specific groups of brain cells that orchestrate specific sex-typical behaviors.”



“If you need to learn how to mate or fight once the situation arises, it’s probably already too late. The evidence is pretty clear that the brain isn’t purely a blank slate just waiting around to be shaped by environmental influences.”&nbsp;



“Mice aren’t humans,” he added. “But it’s reasonable to expect that analogous brain cell types will be&nbsp;shown to play roles in our sex-typical social behaviors.”



Professor Shah and his colleagues also discovered over 600 differences in gene-activation levels between females in different phases of their estrous cycle.&nbsp;



“To find, within these four tiny brain structures, several hundred genes whose activity levels depend only on the female’s cycle stage was completely surprising,” said Shah. The differential activation of these genes regulates females’ estrogen and progesterone levels at different stages of their estrous cycle, and strongly influence their behaviors, such as sexual receptivity.&nbsp;



Finally, some of the genes identified by the researchers are known to be risk factors for various brain disorders in humans, including multiple sclerosis (MS), <a href="https://www.earth.com/news/drinking-coffee-protects-against-alzheimers-disease/">Alzheimer’s disease</a>, or autism. For example, genes linked to increased risk of MS and Alzheimer’s, which tend to afflict women more than men, are more activated in the brains of female mice, whereas genes related to autism, an illness four times more common in men, are more active in the brains of male mice.&nbsp;



Further research is needed to map in greater detail the sex-related genetic differences between male and female mice, and to assess the similarities and differences between mice and human genomes.

New research published in the journal <a href="about:blank">Current Biology</a> has found that using LED illuminated nets greatly reduced <a href="https://www.earth.com/news/dynamic-ocean-closures-offer-protection-from-accidental-catch/">accidental catch</a> of sharks, rays, sea turtles or other unwanted fish. This leads to a win-win situation for commercial fisheries and marine wildlife.



Gillnets are one of the most widely used fishing gear in coastal areas of the world’s oceans. However, using them often results in the bycatch of animals not targeted by fishers, including endangered, threatened, or protected species such as sharks, rays, sea turtles, or seabirds. This incidental catching of non-target species has contributed to declines in endangered species and has negatively impacted coastal ecosystems.&nbsp;



Luckily, during the last decade, increasingly more LED illuminated gillnets have been manufactured, which proved to be a highly effective solution to the problems entailed by accidental catch. A research team led by <a href="https://www.asu.edu/">Arizona State University</a> (ASU) and the <a href="https://www.wcs.org/">Wildlife Conservation Society</a> attached green LED lights every ten meters on gillnets along the Pacific Coast of Baja California Sur, Mexico to assess to what extent could this method reduce bycatch.



The scientists were amazed to find that using this gear reduced total fisheries bycatch by 63 percent, including a 95 percent reduction in the accidental catch of sharks, skates, and rays, an 81 percent reduction in incidental trapping of Humboldt squids, and a 48 percent reduction in catching unwanted finfish. Fortunately for fishers, this technology still allowed continued catches of targeted species, while significantly reducing bycatch.



“These results demonstrate that the potential benefits of illuminated nets extend well beyond sea turtles, while demonstrating the strong promise for net illumination to mitigate discarded bycatch in similar coastal gillnet fisheries throughout the world’s oceans,” said study lead author Jesse Senko, an expert in animal behavior and fisheries management at ASU.



“Making life easier for fishers by reducing the amount of time untangling bycatch is equally essential as reducing the bycatch biomass in nets,” added study co-author John Wang, a fisheries ecologist at the <a href="https://www.fisheries.noaa.gov/about/pacific-islands-fisheries-science-center">Pacific Islands Fisheries Science Center</a>.



“It is important for fishers to know that there are tangible benefits for them. This is critical for the adoption of such technologies by the fishing industry,” he concluded.

Lighted nets help protect endangered marine wildlife

New research published in the journal Current Biology has found...

New research led by the <a href="https://www.washington.edu/">University of Washington</a> has found that a substance in pomegranates called “urolithin A” could be used to create novel anti-aging treatments that strengthen muscles and mitochondrial health and thus protect against frailty in old <a href="https://www.earth.com/news/space-travel-may-cause-premature-aging/">age</a>.



Urolithin A is a by-product of a person’s gut bacteria and a diet rich in polyphenols – substances found in pomegranates, berries, and nuts. Since several factors, including age, diet, genetics, or illness, affect the composition of the gut microbiome, people produce urolithin A at different rates. Now, this substance is also available in pill and powder supplements found in health food stores.



Both in its natural and synthetic form, urolithin A boosts the mitochondria – our cell’s “power stations” – which tend to run down with age, causing muscle weakening and frailty. According to scientists, urolithin A helps the body recycle mitochondria by stimulating a process called mitophagy.



“Mitochondria&nbsp;are like batteries that power the cells in your body,” said study senior author David Marcinek, an expert in the role of mitochondria in human metabolism at the University of Washington.



“But over time, they break down. The process of mitophagy recognizes this failure and proactively tears down the mitochondria, reducing it to elemental components that a cell can reuse. But with aging, mitophagy becomes less efficient and your body accumulates this pool of failing mitochondria. It’s one way that muscles become less functional as we age.”



Professor Marcinek and his colleagues enrolled 66 participants who randomly received either 1,000 mg of an urolithin supplement daily for four months or a placebo. At the beginning of the experiment, they had lower levels of adenosine triphosphate (ATP), a substance produced by mitochondria that helps cell function properly.



The scientists found that the supplement group’s fitness and ATP production improved significantly after the treatment, suggesting that urolithin A may indeed help restore bodily capacities in the elderly.



“Even though we did not observe an effect of the supplement in whole body function,” Professor Marcinek said, “these results are still exciting because they demonstrate that just taking a supplement for a short duration actually improved muscle endurance. Fatigue resistance got better in the absence of exercise.”



“I think these changes suggest that&nbsp;the treatment affects&nbsp;the metabolic condition of people. Even though it didn’t affect the maximum ATP production, it improved test subjects’ general metabolism. Just getting them over that point where exercise is possible – a walk around the block or climbing some stairs – might help a person build their own health,” he concluded.&nbsp;



The study is published in the journal <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2788244?utm_source=For_The_Media&amp;utm_medium=referral&amp;utm_campaign=ftm_links&amp;utm_term=012022">JAMA Network Open</a>.

Today’s Video of the Day from the <a href="https://www.nsf.gov/">National Science Foundation</a> explains that most of the elements that make up the Earth, humans, and all living creatures were formed in stars. Powerful stellar explosions are the source of many of the elements of the periodic table, including those that make up the human body.



According to Live Science, the carbon, nitrogen and oxygen atoms in the human body - as well as atoms of all other heavy elements - were created in previous generations of stars over 4.5 billion years ago. Professor Chris Impey from the University of Arizona explained that because humans and all animals contain these elements, we are literally made of star stuff.



Dr. Ashley King is a planetary scientist and meteorite researcher at the Natural History Museum."It is totally 100% true: nearly all the elements in the human body were made in a star and many have come through several supernovas," said Dr. King.



He explained that it's very likely that there are a whole bunch of different stars that have contributed the elements we see in our own solar system, our planet, and those found within human bodies.&nbsp;



"At the atomic scale, we are all made of the same things. Where did those atoms come from? Every element was forged in the cosmos, from stars that collapse and collide to black holes that fire jets deep into space," reports the National Science Foundation.



"Not only are we 'made of star stuff,' we are made of atoms that were forged in some of the most intense environments in the universe."



NASA gets very specific on the subject, noting that the hydrogen in your body, present in every molecule of water, came from the Big Bang.&nbsp;



"There are no other appreciable sources of hydrogen in the universe," said NASA. "The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away."

Cleaning up oil using bacteria Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes how bacteria could potentially be used to help clean up oil spills.&nbsp;



After the Deepwater Horizon disaster, oil continued to spill into the ocean for three months. As experts were trying to get the situation under control, bacteria were already helping to eliminate oil in the ocean by absorbing and metabolizing it.&nbsp;



Bacteria can also remove other harmful substances from the environment. For example, some species of bacteria can be used to soak up uranium, the radioactive element used in nuclear reactors. Other types of bacteria, meanwhile, could help us clean up oil spills by chowing down large quantities of oil. Say hello to marine microorganisms that can degrade several major chemical components of oil by using these hydrocarbons as a source of energy. By doing so, they can effectively assist in clean-ups following oil spills.



Microbes also have considerable potential when it comes to cleaning up the mess oil sometimes makes. “There are a wide variety of microbes that are able to degrade hydrocarbons in oil, (and) some are better at it than others,” Li said.

Today’s Video of the Day from the <a href="https://www.nsf.gov/">National Science Foundation</a> describes the environmental threat of monogenetic volcanoes. Even though these volcanoes only erupt once in their lifetime, the eruption can last for years or even decades.&nbsp;



A recent study led by the University of Buffalo, which is published in the journal Geosphere, provides an overview of what we know about monogenetic volcanism in the U.S. Southwest over the past 2.58 million years. During this geologic period - known as the Quaternary - more than 1,800 monogenetic volcanoes erupted across Nevada, Utah, Arizona, Colorado, New Mexico and parts of California’s eastern edge.



“Monogenetic means ‘one life,’” explained study lead author and UB volcanologist Greg Valentine. “So a monogenetic volcano will erupt once, and that eruption may last for several days to several decades, but after that, the volcano is basically dead."



“In the United States, most volcanic hazards-related attention has rightly gone to places like Hawaii, and to the Pacific Northwest and Alaska, where we have big stratovolcanoes like Mount Rainier and Mount St. Helens, which will have many eruptive episodes over a long life, with widespread hazardous effects. In the past, these smaller monogenetic volcanoes really haven’t been looked at from a focus on hazards; they have been instead studied mainly for what they tell us about the deep Earth."



“Recently, however, there has been more buzz in the research community about how we need to take a look at the kinds of hazards these volcanoes might pose. My experience with the general public is that most people are surprised to know that there are so many young volcanoes in the Southwest.”



The study highlights gaps in our knowledge of one life volcanoes, and the researchers hope that it can serve as a launchpad for future research.



Based on the number of volcanoes that erupted in the study region during the Quaternary Period, the chances of a new volcano emerging in the area within 100 years would be about 8 percent, said Valentine. However, he noted that this figure does not account for buried volcanoes, or the fact that a single eruption can create multiple vents. 



“There’s so much uncertainty here, and this is part of the problem. It’s kind of a wide-open research field. When you look at the region from the perspective of volcanic hazards, we really have very little information. Most of the volcanoes have not been dated, so we don’t know how old they are, except that they likely formed sometime within the Quaternary Period. Very few have been studied in detail.”

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Cancún, located on the northeast coast of Mexico’s Yucatán Peninsula.



With a long stretch of tropical beaches on the Caribbean Sea, Cancún is one of Mexico’s top tourist destinations.



The Cancún Island resort area, just off the coast, is linked by two causeways at each end.&nbsp;



To the north of Cancún, Isla Contoy is an important nesting place for more than 150 species of birds.



The El Eden Ecological Reserve is located 50 kilometers northwest of Cancún, and Yum Balam Flora and Fauna Protected Area is located near the northeastern tip of the Yucatán Peninsula.



According to ESA, Yum Balam is home to several endangered species including jaguars, crocodiles and monkeys.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features a time lapse of the Northern lights, also known as aurora borealis, captured from space. The images were acquired in November of 2021 during ESA astronaut Thomas Pesquet’s second mission to the International Space Station, the Alpha mission.&nbsp;



According to ESA, the camera was set up to take pictures at intervals of two per second, and the time lapse video plays 25 pictures a second.&nbsp;



The fascinating light show, which can be viewed at both the north and south poles, is produced when energized particles from the sun slam into Earth's upper atmosphere at speeds of up to 45 million miles per hour. Earth's magnetic field redirects the particles toward the poles, creating the fascinating waves of light.&nbsp;



The earliest known record of the northern lights is in a cave painting in France that dates back 30,000 years.&nbsp; In 1619, Italian astronomer Galileo Galilei named the northern lights "aurora borealis" after the Roman goddess of dawn (Aurora) and the Greek god of the north wind (Boreas).



When Pesquet shared the stunning Alpha mission video on social media, he noted that the pictures were taken from the docked Crew Dragon spacecraft windows. Pesquet said it was the strongest aurora the crew had seen during their six months in space.



Updates on the Alpha mission can be found on Twitter via @esaspaceflight.

Spectacular astronaut view of the northern lights

As Sean patrolled the area, he couldn&#8217;t find anything out of the ordinary. When he really focused, however, he thought he could hear a faint whimpering somewhere under the rubble. Sean followed the noise and started digging. Photo credit: Mercury Press and Media

Strange sound

Even when Sean wasn't on patrol, the army life was a grind. Exciting moments in the camp were few and far between, and troop morale suffered greatly. When Sean got a call to investigate a bombed-out school in February, he was almost grateful. Photo credit: Tom Bonnett
