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…
After taking an in-depth look at the basic biology of a fungus that is decimating bat colonies as it spreads across the U.S., researchers report that they can find little that might stop the organism from spreading further and persisting indefinitely in bat caves. Their report appears in the journal PLOS ONE. The aptly named fungus Pseudogymnoascus (Geomyces) destructans causes…
Researchers at the Salk Institute for Biological Studies have, for the first time, taken chimpanzee and bonobo skin cells and turned them into induced pluripotent stem cells (iPSCs), a type of cell that has the ability to form any other cell or tissue in the body. Mouse iPSCs were created in 2006 by Kazutoshi Takahashi and Shinya Yamanaka at Kyoto…
If a 6-month-old can distinguish between 20 dots and 10 dots, she’s more likely to be good at math in preschool. That’s the conclusion of a new study, which finds that part of our proficiency at addition and subtraction may simply be something we’re born with. Researchers have long wondered where our math skills come from. Are they innate, or…
