  • Removing sweets from checkouts linked to dramatic fall in unhealthy snack purchases
    Policies aimed at removing sweets and chips from checkouts could lead to a dramatic reduction to the amount of unhealthy food purchased to eat 'on the go' and a significant reduction in that purchased to take home, suggests new research.... Read more »
  • Southwest forest trees will grow much slower in the 21st century
    Southwest forests may decline in productivity on average as much as 75 percent over the 21st century as climate warms. The finding is based on a treasure trove of about 20,000 unanalyzed tree cores discovered in a Utah laboratory about a decade ago.... Read more »
  • Using CRISPR technology for conditional gene regulation
    CRISPR allows scientists to precisely target and edit DNA within living cells, which could help them correct anomalies that cause inherited diseases. A team has now developed a method to use CRISPR/Cas9 technology to set off a cascade of activities in cells, a phenomenon known as conditional gene regulation.... Read more »
  • Gender separation affects sense of smell
    Olfactory sensory receptors in mice change as a function of exposure to odors emitted from members of the opposite sex, researchers have discovered.... Read more »
  • Uncovering a key mechanism in assembly of Avian Sarcoma Virus, a relative of HIV-1
    Researchers used NMR to detail how the matrix domain of the Avian Sarcoma Virus Gag protein binds to certain phospholipids. These phospholipids are vital for Gag protein binding to the plasma membrane of a cell, as the virus replicates and takes its first step toward virus formation and budding. ASV... Read more »
  • System monitors radiation damage to materials in real-time
    (Massachusetts Institute of Technology) A new system allows detailed real-time observations of how materials are affected by a high-radiation environment. The system, developed at MIT and Sandia National Laboratories, could accelerate the development of better materials for nuclear plants.... Read more »
  • Sarpeshkar elected to the National Academy of Inventors
    (Thayer School of Engineering at Dartmouth) Rahul Sarpeshkar, professor of engineering at Thayer School of Engineering at Dartmouth, has been named a fellow of the National Academy of Inventors (NAI). Sarpeshkar is a leader in the fields of medical devices and electronics as well as ultra-low power, analog, and... Read more »
  • The vanished mirror image
    (Technical University of Munich (TUM)) Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently only one of the two forms is effectual in biology and medicine. Hitherto, completely converting this mixture into the desired enantiomer was deemed impossible. Deploying a...

  • Pathogen predicament: How bacteria propel themselves out of a tight spot
    (University of York) Scientists have deciphered how some types of 'swimming' bacteria have evolved to be able to escape when trapped in small spaces.The discovery could pave the way to finding new methods to stop the spread of certain bacteria, including species that cause food poisoning and stomach ulcers....
