Uncertainty of future Southern Ocean CO2 uptake cut in half
The Southern Ocean dominates the oceanic uptake of human-made CO2. But how much carbon dioxide can it actually absorb in the future? This long-standing question remained unresolved as projections of different generation of climate models repeatedly showed a wide range of future Southern Ocean CO2 sink estimates. Climate scientists from Bern have now been able to reduce this large uncertainty by about 50 percent.

National cardiogenic shock initiative results demonstrate increased heart attack survival
The results of a large, national heart attack study show that patients with a deadly complication known as cardiogenic shock survived at a significantly higher rate when treated with a protocol developed by cardiologists at Henry Ford Hospital in collaboration with four metro Detroit hospitals.

IPK scientists identify networks for spikelet formation in barley
In a long-standing research project, an international research team led by the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) has used lasers to excise and analyse the finest tissue parts involved in barley spikelet organ formation. The results are of immense importance for further comparative studies among other grass or cereal crops and have recently been published in the journal Science Advances.

Deep under the ocean, microbes are active and poised to eat whatever comes their way
The subseafloor constitutes one of the largest and most understudied ecosystems on Earth. An interdisciplinary research team, led from ASU and the Woods Hole Oceanographic Institution (WHOI), sought to learn more about this ecosystem by studying North Pond on the western flank of the mid-Atlantic Ridge, a plate boundary located along the floor of the Atlantic Ocean. They found microbes that were active and poised to eat.

Category killers of the internet are significantly reducing online diversity
New research shows that the variety of online players is shrinking rapidly, although the overall size of the worldwide web continues to expand and functional and geographic opportunities are rising.

Combined recognition strategy allows CAR T cells to kill solid tumors in mice and avoid side effects
Two teams have created a new generation of highly specific CAR T cells, which safely cleared solid tumors in mice with mesothelioma, ovarian cancer, and the deadly brain cancer glioblastoma while outlasting and outperforming conventional CAR T cell designs.

How to get salt out of water: Make it self-eject
MIT researchers have uncovered a mechanism by which dissolved salts can crystallize in a way that makes it easy to remove them from surfaces, potentially helping to prevent fouling of metal surfaces.

Cave deposits reveal Pleistocene permafrost thaw, absent predicted levels of CO2 release
Expanding the study of prehistoric permafrost thawing to North America, researchers found evidence in mineral deposits from caves in Canada that permafrost thawing took place as recently as 400,000 years ago, in temperatures not much warmer than today. But they did not find evidence the thawing caused the release of predicted levels of carbon dioxide stored in the frozen terrain.

Cave deposits show surprising shift in permafrost over the last 400,000 years
Earth's permafrost shifted to a more stable state in the last 400,000 years and has been less susceptible to thawing since then, according to a new study by MIT researchers and their colleagues.

In wild soil, predatory bacteria grow faster than their prey
In wild soil, bacteria that eat other bacteria consume more resources and grow faster than their prey, a new study from Northern Arizona University finds. The results of the study, published in the journal mBio this week, show predation is an important dynamic in the wild microbial realm, and suggest that these predators play an outsized role in how elements are stored in or released from soil.

Research on Lake Victoria cichlids uncovers the processes of rapid species adaptation
Scientists at Tokyo Institute of Technology (Tokyo Tech) have recently published the results of their investigations into adaptive radiation, which is when organisms rapidly evolve from an ancestral species into novel forms. Their genetic analyses of cichlids in Lake Victoria highlight several candidate genes that may drive adaptive radiation and provide evidence for decisive selective events that cause particular genetic variants to quickly gain dominance within populations. These findings broaden scientific understanding of how new species arise.

Socially just population policies can mitigate climate change and advance global equity
Socially just policies aimed at limiting the Earth's human population hold tremendous potential for advancing equity while simultaneously helping to mitigate the effects of climate change, Oregon State University researchers say.

Severe COVID-19 cases can be predicted by new test
As of April 2021, more than 3 million people worldwide have died of COVID-19. Early in the pandemic, researchers developed accurate diagnostic tests and identified health conditions that correlated with worse outcomes. However, a clinical predictor of who faces the highest risk of being hospitalized, put on a ventilator or dying from the disease has remained largely out of reach.

Soil bacteria evolve with climate change
While evolution is normally thought of as occurring over millions of years, researchers at the University of California, Irvine have discovered that bacteria can evolve in response to climate change in 18 months. In a study published in the Proceedings of the National Academy of Sciences, biologists from UCI found that evolution is one way that soil microbes might deal with global warming.

The diploid genome assemblies in marmoset shows huge variations
The international consortium today announces a series of publications in a special collection of Nature that resulted from the first phase of the Vertebrate Genome Project (VGP) to release 16 high quality reference genomes. The research group led by Professor Guojie Zhang of the Department of Biology has made substantial contributions to the VGP and this first wave of publications.

The science of picky shoppers
A new series of Penn State studies has found that shopper pickiness can go beyond shopping for the "best" option. The researchers define what it means to be "picky" and also developed a scale for measuring shopper pickiness.

Study finds green spaces linked to lower racial disparity in COVID infection rates
More green spaces in an area is associated with a lower racial disparity in COVID-19 infection rates, according to the first study to examine the relationship between the supply of green spaces and reduced disparity in infectious disease rates.

El Niño can help predict cacao harvests up to 2 years in advance
New research published in the Nature journal Scientific Reports shows that ENSO, the weather-shaping cycle of warming and cooling of the Pacific Ocean along the Equator, is a strong predictor of cacao harvests up to two years before a harvest.

Two compounds can make chocolate smell musty and moldy
Chocolate is a beloved treat, but sometimes the cocoa beans that go into bars and other sweets have unpleasant flavors or scents, making the final products taste bad. Surprisingly, only a few compounds associated with these stinky odors are known. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have identified the two compounds that cause musty, moldy scents in cocoa -- work that can help chocolatiers ensure the quality of their products.

Study finds people of color more likely to participate in cancer clinical trials
People of color, those with a higher income and younger individuals are more likely to participate in clinical trials during their cancer treatment according to a new study from the University of Missouri School of Medicine.
