As global temperatures continue to rise, scientists have long worried that mountain species are on an "extinction elevator"—forced to move uphill for cooler temperatures, ultimately accelerating extinction as they run out of space. However, a new study led…

This year 80 people put on their waders, grabbed buckets and quadrats (square metal frames), and splashed through the clear shallow waters. Once they reached one of the many sampling locations, marked by miniature floats, they threw their quadrats into the…

Rwanda's biggest national park announced on Thursday it will be receiving 70 white rhinos from South Africa later this month, in the country's largest such transfer ever.

Ask scientists which gene-editing tool is most needed to advance gene therapy, and they'd probably describe a system that's now close to realization in the labs of Samuel Sternberg at Columbia University Vagelos College of Physicians and Surgeons and David Liu…

ARS scientists made a "sweet" discovery that may be important to solving a major problem within the citrus industry.

The horse originated in North America around four million years ago. As changing sea levels created land bridges between continents, the horse traveled into Eurasia. A team of 57 international researchers—including 18 Indigenous scientists from the Lakota,…

Research from Ph.D. candidate Bohan Chen in the lab of Idse Heemskerk of the Department of Cell and Developmental Biology at the University of Michigan Medical School and their colleagues improves upon a popular experimental model, and in doing so, reveals…

The seagrass is greener along Florida's Nature Coast … figuratively, that is. A new study published in the journal Marine Ecology Progress Series shows that seagrass ecosystems along the northern half of Florida's Gulf Coast have remained relatively healthy…

Especially in temperate climates, winter poses a major challenge for honeybee colonies. To ensure their survival, the animals must maintain the right temperature in the hive and raise the next generation of workers. The availability of pollen from flowers…

Scientists at the McGovern Institute and the Broad Institute of MIT and Harvard have reengineered a compact RNA-guided enzyme they found in bacteria into an efficient, programmable editor of human DNA. The engineered protein, called NovaIscB, can be adapted to…

Sterols, such as cholesterol in our bodies or ergosterol in yeast cells, are among the most abundant lipids in eukaryotic cells, yet are synthesized through notoriously long, complex metabolic pathways.

The dairy and agriculture sectors' pursuit of sustainability and efficiency has fueled a dramatic expansion in research aimed at understanding and reducing livestock greenhouse gas emissions. Central to this effort is the ability to accurately measure methane…

A team of wildlife researchers from Instituto Nacional de Pesquisas da Amazônia, in Brazil, working with a colleague from the National Museum of the Czech Republic, has discovered a new species of poison dart frog in the Brazilian Amazon rainforest. In their…

Schoolchildren in America learn the story of the "three sisters" in agriculture: how Indigenous peoples planted corn, beans and squash in the same plots because these plants thrive together better than when they are planted alone.

Each year, between March and October, large amounts of brown seaweed called sargassum wash up on the shores of Caribbean islands—choking beaches, damaging marine life and threatening tourism and public health. But a number of local entrepreneurs are hoping…

A group of researchers, including scientists from the DTU National Food Institute, have developed a method that, with the help of artificial intelligence and DNA decoding, can predict how well disease-causing bacteria such as Listeria tolerate disinfectants.…

Cats, dogs and farm animals are what come to mind when we think of domesticated animals. For ages, domestication has been portrayed as a uniquely human accomplishment, where species become domestic only through our deliberate control.

Auxin is the first plant hormone—or "phytohormone"—ever identified, with its discovery dating to the late 19th and early 20th centuries. With its discovery, scientists began to understand how small, self-produced organic molecules could influence…

Researchers from Radboudumc, Department of Human Genetics, demonstrated something remarkable in a 2014 publication in Nature. Contrary to expectations, inherited variants in genes were rarely responsible for intellectual disability. In the vast majority, the…

A new study has compared how migrating humpback whales use two stopover sites along the Queensland coast, finding that one was more social in nature and the other was used primarily by mothers and calves.
