Bird brains left other dinosaurs behind

Today, being "birdbrained" means forgetting where you left your keys or wallet. But 66 million years ago, it may have meant the difference between life and death—and may help explain why birds are the only dinosaurs left ...

A single cell type map of human tissues

In a study published in the US journal Science Advances, a single cell type map of human tissues is presented. An open access atlas has been launched with more than 250,000 interactive plots to allow researchers to explore ...

Some birds observed stealing hair from living mammals

Dozens of online videos document an unusual behavior among tufted titmice and their closest bird kin. A bird will land on an unsuspecting mammal and, cautiously and stealthily, pluck out some of its hair.

Scientists create embryos to save northern white rhino

Scientists working to bring back the functionally extinct northern white rhino announced they had successfully created three additional embryos of the subspecies, bringing the total to 12.

Scientists upturn understanding of how key hormones act in cells

Researchers at the University of Virginia School of Medicine have overturned conventional wisdom on the workings of vital hormone receptors within cells, a finding that could boost drug development for diabetes and related ...

Testis-specific gene involved in sex ratio regulation discovered

Although enormous progress has been made over the past few decades in genetics, molecular biology and biochemistry, the ways in which living beings orchestrate their internal processes at the microscopic scale is still full ...

Chromosome positioning during sperm differentiation described

Chromosomes occupy specific regions of the cell nucleus called chromosome territories. In somatic cells, scientists have observed that there is a correlation between this positioning and genome regulation. In fact, alterations ...

Researchers find fat burning molecule in mice

Linked to serious health problems including cancer, diabetes and cardiovascular disease, obesity affects more than a third of adults in the United States. Presently, there are few safe and effective nonsurgical therapeutic ...

Cholera strain becomes unexpectedly resistant to infection by phages

Graduate student Kristen LeGault and assistant professor Kimberley Seed, both in the Department of Plant and Microbial Biology, specialize in the evolution of human pathogens and the viruses that infect bacteria, known as ...

Mapping of genetic control elements in the cerebellum

The mammalian cerebellum has long been associated almost exclusively with motor control, yet recent studies indicate that it also contributes to many higher brain functions. An international research team led by Prof. Dr. ...

Differentiating strong antibiotic producers from weaker ones

An untapped trove of desirable drug-like molecules is hidden in the genomes of Streptomyces bacteria—the same bacteria responsible for the first bacterial antibiotics to treat tuberculosis back in the 1940s.

New insights on flowering could boost cassava crops

Two new publications examining cassava flowering reveal insights into the genetic and environmental factors underpinning one of the world's most critical food security crops.
