A group of international scientists have mapped the genetic, cellular, and structural makeup of the human brain and the nonhuman primate brain. This understanding of brain structure allows for a deeper knowledge of the cellular basis of brain function and dysfunction, helping pave the way for a new generation of precision therapeutics for people with mental disorders and other disorders of the brain.

Synthetic biologists report on a new approach to attacking tumors. They have engineered tumor-colonizing bacteria (probiotics) to produce synthetic targets in tumors that direct CAR-T cells to destroy the newly highlighted cancer cells.

True altruism is rare behavior in animals, but a new study has found that honey bees display this trait. Additionally, they found that an evolutionary battle of genetics may determine the parent they inherit it from.

To study muscle diseases, scientists rely on the mouse as a model organism. Researchers have now developed a new method that is not only faster and more efficient than conventional ones but also greatly reduces the number of experimental animals needed for studying the function of genes in muscle fibers.

Food shortages caused by extreme weather could lead to civil unrest in the UK, according to a new study which has surveyed some of the country’s leading food experts.

Lack of rainfall is not the only measure of drought. New research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years.

Researchers have obtained new insights into how African-American and Hispanic-American people’s genes influence their ability to use Omega-3 and Omega-6 fatty acids for good health. The findings are an important step toward “precision nutrition” – where a diet tailored to exactly what our bodies need can help us live longer, healthier lives.

Every year, around 1,200 and 1,400 artificial turf sports fields are installed in the European Union. These fields are made up of synthetic fibers, mainly plastics, that mimic the appearance of natural grass. Recently, scientists conducted a study that characterizes and quantifies the presence of artificial turf fibers in samples collected from surface waters of the Catalan coast and the Guadalquivir River. The findings indicate that artificial turfs can be an important source of pollution in the aquatic environment, accounting for up to 15% of the plastics larger than 5 mm in length that are found floating in the aquatic environment.

A new study of the microbial ecosystem in sourdough finds that using different types of flour fosters distinct bacterial communities, and that these differences contribute to the variation of sourdough aromas and flavors.

Wine quality is notorious for varying from year to year, but what makes for a 'good year?' Researchers show that weather plays an important role in determining wine quality. By analyzing 50 years’ worth of wine critic scores from the Bordeaux wine region in relation to that year’s weather, the researchers showed that higher quality wine is made in years with warmer temperatures, higher winter rainfall, and earlier, shorter growing seasons—conditions that climate change is predicted to make more frequent.

A massive computational analysis of microbiome datasets has more than doubled the number of known protein families. This is the first time protein structures have been used to help characterize the vast array of microbial 'dark matter.'

DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.

Evolutionary biologists have for the first time decoded the genetic lineage of a famous killer whale and a pod that once worked alongside whale hunters off the coast of Australia. In the Australian tradition of claiming New Zealand's celebrities as its own, Old Tom, the leader of a pod of killer whales that famously helped whalers hunt baleen whales in the 20th century, has ancestral links to modern-day killer whales in New Zealand, according to new DNA research. Old Tom also shared a common ancestor with killer whales from Australasia, the North Pacific, and North Atlantic Oceans, but is most similar to modern New Zealand killer whales. However, most of Tom's DNA code is not found in other killer whales globally suggesting that the killer whales of Eden may have become extinct locally.

Research finds that experiencing days in which the temperature exceeds previous highs for that time of year affects people’s perception of weather trends.

Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan now supports the idea.

With global warming apparently here to stay, a team of paleoclimatologists are studying an ancient source to determine future rainfall and drought patterns: fossilized plants that lived on Earth millions of years ago.

Can plant-derived nutrients alter gut bacteria to affect brain function? Scientists investigated this question in a study of overweight adults. Their findings suggest that dietary fiber can exert influence on both the composition of gut bacteria and the reward signals in the brain and associated food decision-making.

An international team of scientists have discovered a huge spike in radiocarbon levels 14,300 years ago by analyzing ancient tree-rings found in the French Alps. The radiocarbon spike was caused by a massive solar storm, the biggest ever identified.  A similar solar storm today would be catastrophic for modern technological society – potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions. The academics are warning of the importance of understanding such storms to protect our global communications and energy infrastructure for the future.

The Gulf Stream is intrinsic to the global climate system, bringing warm waters from the Caribbean up the East Coast of the United States. As it flows along the coast and then across the Atlantic Ocean, this powerful ocean current influences weather patterns and storms, and it carries heat from the tropics to higher latitudes as part of the Atlantic Meridional Overturning Circulation.  A new study now documents that over the past 20 years, the Gulf Stream has warmed faster than the global ocean as a whole and has shifted towards the coast. The study relies on over 25,000 temperature and salinity profiles collected between 2001 and 2023.
