As Supreme Court Justice Elena Kagan questioned Myriad Genetics’ attorney about patenting genes, Chris Hansen rejoiced. The attorney said that yes, genes should be patentable. But it was only under the pressure of further questions that he said that chromosomes, too, should be patentable, and — more reluctantly still — organs such as kidneys. “It was all I could do…
Professor of Genetics Scott Williams, PhD, of the Institute for Quantitative Biomedical Sciences (iQBS) at Dartmouth’s Geisel School of Medicine, has made two novel discoveries: first, a person can have several DNA mutations in parts of their body, with their original DNA in the rest—resulting in several different genotypes in one individual—and second, some of the same genetic mutations occur…
All animals have to make decisions every day. Where will they live and what will they eat? How will they protect themselves? They often have to make these decisions as a group, too, turning what may seem like a simple choice into a far more nuanced process. So, how do animals know what’s best for their survival? For the first…
Only a few genetic changes are needed to spur the evolution of new species — even if the original populations are still in contact and exchanging genes. Once started, however, evolutionary divergence evolves rapidly, ultimately leading to fully genetically isolated species, report scientists from the University of Chicago in the Oct. 31 Cell Reports. “Speciation is one of the most…
Researchers from Nanjing Normal University and BGI report their original genomic research on Baiji, also known as Yangtze River dolphin (Lipotes vexillifer). The study gives new insight into the genetic and evolutionary adaptations of Dolphin, and provides valuable resources for the conservation of mammals and cetaceans in particular. The latest study was published online in the journal Nature Communications. Nicknamed…
Light enhances brain activity during a cognitive task even in some people who are totally blind, according to a study conducted by researchers at the University of Montreal and Boston’s Brigham and Women’s Hospital. The findings contribute to scientists’ understanding of everyone’s brains, as they also revealed how quickly light impacts on cognition. “We were stunned to discover that the…
