Cross species transfer of genes has driven evolution
Far from just being the product of our parents, University of Adelaide scientists have shown that widespread transfer of genes between species has radically changed the genomes of today's mammals, and been an important driver ...
Neuroscientists uncover secret to intelligence in parrots
University of Alberta neuroscientists have identified the neural circuit that may underlie intelligence in birds, according to a new study. The discovery is an example of convergent evolution between the brains of birds and ...
T cell engineering breakthrough sidesteps need for viruses in gene-editing
In an achievement that has significant implications for research, medicine, and industry, UC San Francisco scientists have genetically reprogrammed the human immune cells known as T cells without using viruses to insert DNA. ...
Australian feral cats kill a million reptiles a day: study
Feral cats kill more than one million reptiles every day in Australia, a new study showed Monday, with the staggering slaughter threatening many species.
Biochemists discover cause of genome editing failures with hyped CRISPR system
Researchers from the University of Illinois at Chicago are the first to describe why CRISPR gene editing sometimes fails to work, and how the process can be made to be much more efficient.
Study suggests dogs have lost ability to reconcile after violent conflicts
Spiders go ballooning on electric fields
The aerodynamic capabilities of spiders have intrigued scientists for hundreds of years. Charles Darwin himself mused over how hundreds of the creatures managed to alight on the Beagle on a calm day out at sea and later take-off ...
Monarchs ride west coast winds: Proof of butterfly migration gathered
After five years and nearly 15,000 tagged butterflies, scientists now have proof that Monarch butterflies migrate from the Pacific Northwest to California in late summer and fall, a journey averaging nearly 500 miles.
