  • NASA'S OSIRIS-REx spacecraft slingshots past Earth
    NASA's asteroid sample return spacecraft successfully used Earth's gravity on Friday to slingshot itself on a path toward the asteroid Bennu, for a rendezvous next August.... Read more »
  • Mechanism that underlies age-associated bone loss
    A major health problem in older people is age-associated osteoporosis -- the thinning of bone and the loss of bone density that increases the risk of fractures. Researchers have now detailed an underlying mechanism leading to that osteoporosis. When this mechanism malfunctions, progenitor cells stop creating bone-producing cells, and instead... Read more »
  • Two Group A Streptococcus genes linked to 'flesh-eating' bacterial infections
    Group A Streptococcus bacteria cause illnesses ranging from mild nuisances like strep throat to life-threatening conditions such as flesh-eating disease, also known as necrotizing fasciitis. Life-threatening infections occur when the bacteria spread underneath the surface of the skin or throat and invade the underlying soft tissue. Researchers have found two... Read more »
  • Enhancing the sensing capabilities of diamonds with quantum properties
    When a nitrogen atom is next to the space vacated by a carbon atom, it forms what is called a nitrogen-vacancy center. Now, researchers have shown how they can create more NV centers, which makes sensing magnetic fields easier, using a relatively simple method that can be done in many... Read more »
  • 700 years old saint myth has been proven (almost) true

  • Winter cold extremes linked to high-altitude polar vortex weakening
    (Potsdam Institute for Climate Impact Research (PIK)) When the strong winds that circle the Arctic slacken, cold polar air can escape and cause extreme winter chills in parts of the Northern hemisphere. A new study finds that these weak states have become more persistent over the past four decades and... Read more »
