When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research, two key elements of our innate immune system came from a group of microbes called Asgard archaea. Read more ›

Scientists have found infants and young children treated for brain tumors fell behind early in academic readiness, which predicted falling behind in later school years. Read more ›

New research shows that rainwater could have helped create a meshy wall around protocells 3.8 billion years ago, a critical step in the transition from tiny beads of RNA to every bacterium, plant, animal, and human that ever lived. Read more ›

Who are we? Why are we here? We are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic molecules, researchers investigated the role of low-energy electrons created as cosmic radiation traverses through ice particles. Their findings may also inform medical and environmental applications on our home planet. Read more ›

A new study addresses the lack of data on how much human-generated carbon dioxide is present in coastal oceans -- the saltwater ecosystems that link the land and sea. Capturing this data is crucial to calculating how much emissions must be cut in the future. Read more ›

Honey bees may play a role in increasing virus levels in wild bumble bees each spring, according to researchers who analyzed seasonal trends of parasite and virus transmission in bees. Read more ›

When giant ragweed takes hold in a crop field, the towering weed reduces yield and sends plumes of its famously allergy-inducing pollen into the air. There are few tools available to thwart the menace, especially for farmers growing non-GMO soybeans. Now, some Wisconsin farmers are left with even fewer options. Read more ›

An enzyme called PGK1 has an unexpectedly critical role in the production of chemical energy in brain cells, according to a preclinical study. The investigators found that boosting its activity may help the brain resist the energy deficits that can lead to Parkinson's disease. Read more ›

In preclinical models, the inhalation of a mixture of living Lactobacilli bacteria attenuated pulmonary inflammation and improved lung function and structure for the chronic lung diseases bronchopulmonary dysplasia and chronic obstructive pulmonary disease. This study determined the mechanism of this live biotherapeutic product -- a powder mixture of living Lactobacilli bacteria -- to reduce neutrophilic inflammation and reduce a broad swath of inflammatory markers in BPD and COPD.

New research has revealed how an underwater avalanche grew more than 100 times in size causing a massive trail of destruction as it traveled 2000km across the Atlantic Ocean seafloor off the North West coast of Africa. Researchers provide an unprecedented insight into the scale, force and impact of one of nature's mysterious phenomena, underwater avalanches. Read more ›

Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal....

Homicide is a major reason behind lower and more variable reduction in life expectancy for Black rather than White men in recent years, according to a new study. Read more ›

A new study challenges as highly unlikely an alarming prediction of sea-level rise that -- while designated as low likelihood --earned a spot in the latest UN climate report for its projection that the collapse of polar ice sheets could make the world's oceans up to 50 feet higher by 2300. But researchers found that the model is based on inaccurate physics of how ice sheets retreat and break apart,... Read more ›

A team of researchers has developed the first transmission electron microscope which operates at the temporal resolution of a single attosecond, allowing for the first still-image of an electron in motion. Read more ›

Researchers used machine learning to determine how much global warming has influenced extreme weather events in the U.S. and elsewhere in recent years. Their approach could change how scientists study and predict the impact of climate change on extreme weather. Read more ›

Human-wildlife overlap could increase across about 57% of the global lands by 2070 and could lead to more conflict between people and animals. Understanding where the overlap is likely to occur -- and which animals are likely to interact with humans in specific areas -- will be crucial information for urban planners, conservationists and countries that have pledged international conservation commitments.

Neuroticism may moderate the relationship between certain personality traits and self-control, and the interaction effects appear to differ by the type of self-control, according to a new study. Read more ›

An international team of scientists has uncovered a mechanism by which acute myeloid leukemia (AML) cells sustain their growth. AML cells prevent the synthesis of proteins that suppress their growth by forcibly isolating the mRNAs that encode such proteins within structures known as P-bodies. These findings offer a novel perspective into the survival mechanisms of AML and possibilities for new anti-cancer therapies. Read more ›

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit. Read more ›
