A novel optical switch makes it possible to precisely control the lifespan of genetic copies. These are used by the cell as building instructions for the production of proteins. The method was developed by researchers from the...

A study of hundreds of new genomes from across the globe has yielded insights into modern genetic diversity and...
An international team of scientists including the University of Adelaide has discovered a new complex carbohydrate in moss that could possibly be exploited for health or other uses.
The scientists, from Australia's ARC Centre of Excellence in Plant Cell Walls...
The rich levels of biodiversity on land seen across the globe today are not a recent phenomenon: diversity on land has been similar for at least the last 60 million years, since soon after the extinction...
New research out of the University of Chicago has found evidence that the lobe-finned fish species Tiktaalik roseae was capable of both biting and suction during feeding, similar to modern-day gars. These results, published on Feb. 1...
A new tool invented by University of Alberta biologists to sequence circular DNA will provide scientists with richer, more accurate data that could help advance research on viruses, agriculture and perhaps even cancer.
The tool—called...
Brain cancer stem cells (left) are killed by Zika virus infection (image at right shows cells after Zika treatment). A new study shows that the virus, known for killing cells in the brains of developing fetuses, could be redirected...
The call to evolve could be coming from inside the house mouse.
Recent research from the University of Nebraska–Lincoln and University of California, Berkeley suggests that bacteria residing in the digestive tracts of mouse species have partly directed their...
The functional portion of the human genome probably falls between 10 percent and 15 percent, with an upper limit of 25 percent, suggests new research.

The human gut harbors trillions of invisible microbial inhabitants, referred to as the microbiota, that collectively produce thousands of unique small molecules. The sources and biological functions of the vast majority of these molecules are unknown. Yale...
