Study hints at why parrots are great vocal imitators
An international team of scientists led by Duke University researchers has uncovered key structural differences in the brains of parrots that may explain the birds' unparalleled ability to imitate sounds ...
Expanding the DNA alphabet: 'Extra' DNA base found to be stable in mammals
Researchers from the University of Cambridge and the Babraham Institute have found that a naturally occurring modified DNA base appears to be stably incorporated in the DNA of many mammalian tissues, possibly ...
Toothed whales have survived millions of years without key antiviral proteins
Researchers at the Stanford University School of Medicine have determined that toothed whales lack functional Mx genes—a surprising discovery, since all 56 other sequenced mammals in the study possess these ...
Chinese team performs gene editing on human embryo
Nature, nurture, or physics? Researchers answer question about nematode behavior
Nature versus nurture is an age-old question in biology, centering on whether a given trait is determined by an organism's genes or by its environment. Most times the answer is "both," but research at the ...
Scientists pinpoint gene for better rice
Scientists said Monday they had pinpointed variants of a gene to improve the quality and yield of rice, a staple starch for billions of people.
Editing stem cell genes will "revolutionize" biomedical research
Applying a dramatically improved method for "editing" genes to human stem cells, University of Wisconsin-Madison professor of neuroscience Su-Chun Zhang has shown a new way to silence genes in stem cells and their progeny ...
Heaven scent: Finding may help restore fragrance to roses
Shakespeare said a rose by any other name would smell as sweet. In fact, many kinds of roses today have little fragrance. But a new discovery might change that.
First comprehensive analysis of the woolly mammoth genome completed
The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt to life in the arctic. Mammoth genes that differed from their counterparts in ...
How small genetic change in Yersinia pestis changed human history
While studying Yersinia pestis, the bacteria responsible for epidemics of plague such as the Black Death, Wyndham Lathem, Ph.D., assistant professor in microbiology-immunology at Northwestern University Feinbe ...
Study reveals mechanisms of drought response in plants
UNL biologists have published a new study that lays bare several roots of how plants respond to drought.
Attractive female flies harmed by male sexual attention
Too much male sexual attention harms attractive females, according to a new Australian and Canadian study on fruit flies.
Researchers uncover epigenetic switches that turn stem cells into blood vessel cells
Researchers at the University of Illinois at Chicago have identified a molecular mechanism that directs embryonic stem cells to mature into endothelial cells—the specialized cells that form blood vessels. ...
Genetic discovery uncovers key tool for morphine production in poppies
Scientists at the University of York and GlaxoSmithKline (GSK) Australia have made a key genetic discovery in poppies, paving the way for more effective painkillers.
