  • New feather findings get scientists in a flap
    Scientists have revealed that feather shafts are made of a multi-layered fibrous composite material, much like carbon fiber, which allows the feather to bend and twist to cope with the stresses of flight. Since their appearance over 150 million years ago, feather shafts (rachises) have evolved to be some of the lightest, strongest and most fatigue resistant […]
  • Genome editing technique advanced by researchers
    Customized genome editing -- the ability to edit desired DNA sequences to add, delete, activate or suppress specific genes -- has major potential for application in medicine, biotechnology, food and agriculture. Now researchers examine six key molecular elements that help drive this genome editing system, which is known as CRISPR-Cas.
  • Let there be light: Evolution of complex bioluminescent traits may be predictable
    A longstanding question among scientists is whether evolution is predictable. A team of researchers from University of California Santa Barbara may have found a preliminary answer. The genetic underpinnings of complex traits in cephalopods may in fact be predictable because they evolved in the same way in two distinct species of squid.
  • Predicting the predator threatening a squirrel by analyzing its sounds and tail movements
    Biologists found the could quite accurately predict what type of predator was threatening a squirrel by analyzing its sounds and tail movements.
  • Ancient Europeans intolerant to lactose for 5,000 years after they adopted agriculture
    By analyzing DNA from petrous bones of ancient Europeans, scientists have identified these peoples remained intolerant to lactose (natural sugar in the milk of mammals) for 5,000 years after they adopted agricultural practices. The scientific team examined nuclear ancient DNA extracted from thirteen individuals from burials from archaeological sites in the G […]
