  • Does the "Wang particle" exist?
    Reports related to the theoretical "Wang particle," an entity that could explain supernovas in the universe, have surfaced recently. Charles Wang, head of the University of Aberdeen's Quantum Gravity and Gauge Group, and colleagues attest that the particle might be produced if a massive star's iron core releases ripples in space-time that diffuse like supernova explosions and sound waves. Scientists are set to search for evidence of the particle at the On-Line Isotope Mass Separator ISOLDE facility of CERN in November.

  • Human genome study could unlock the biology of disease
    An international research effort called ENCODE, or the Encyclopedia of DNA Elements, showed that human DNA has millions of on-off switches and complex networks that control the genes' activities. The study discovered that at least 80% of the human genome is active, which opposed the previously held idea that most of the DNA are useless. Scientists expect the study to help in the search for the biology of disease, specifically common conditions including heart disease, asthma and high blood pressure.

  • Researchers find cell that gives birth to entire immune system
    Researchers at the University of California, Los Angeles, have discovered the progenitor cell that serves as the "missing link" between bone marrow stem cells and all human immune system cells, according to a study in the journal Nature Immunology. The findings could allow treatments that help build stronger immune systems, a researcher said. Examiner.com (9/2) LinkedInFacebookTwitterEmail this Story
  • Vitamin D accelerates recovery of tuberculosis patients
    A combination of high doses of vitamin D and antibiotic treatment helped tuberculosis patients heal faster, according to a British study published in the journal Proceedings of the National Academy of Sciences. The findings suggest that exposure to high levels of vitamin D slows down inflammatory responses to infection, which in turn protects the lungs from damage.

  • Dawn spacecraft leaves asteroid, NASA says
    NASA announced that the Dawn spacecraft left the asteroid Vesta, which it mapped over the past year, on Wednesday. The probe has captured several photos of the giant space rock. It now heads toward the dwarf planet Ceres and is expected to enter the planet's orbit in February 2015. Space.com (9/5) LinkedInFacebookTwitterEmail this Story
  • NASA: Grail probes start lunar gravity mission
    A pair of NASA's Gravity Recovery and Interior Laboratory, or Grail spacecraft, started gathering data on lunar gravity Aug. 30 as they enter their extended science phase. "The data collected during Grail's primary mission are currently being analyzed and hold the promise of producing a gravity field map of extraordinary quality and resolution," said Maria Zuber, Grail principal investigator from the Massachusetts Institute of Technology. The phase is set to run until Dec. 3. Space.com (9/4) LinkedInFacebookTwitterEmail this Story
  • Archaeologists locate church where king is said to be buried
    Archaeologists looking for the grave of King Richard III confirmed Wednesday that they have found the location of the Greyfriars church, believed to be his final resting place, beneath a parking lot in Leicester, England. University of Leicester archaeologists found what seemed to be the alignment of the church building's walls at a third trench site. The team plans to dig further to search for the church's high alter and choir, which is recorded in history as the king's grave site. LiveScience.com (9/5) LinkedInFacebookTwitterEmail this Story
  • Scientists create stretchy, tough hydrogel material
    Scientists have created a tough hydrogel that can be stretched to more than 20 times its original length without being ruptured. They tested the compound, which was made from water, alginate and polyacrylamide, by dropping a stainless-steel ball on the material as well as fastening it in a stretching machine. The hydrogel could be used as artificial cartilage, the researchers say. InnovationNewsDaily.com (9/5) LinkedInFacebookTwitterEmail this Story
  • Biofuel byproduct could power fuel cells
    A science team from the University of Surrey says a material called distillers dried grains with solubles from bioethanol production shows promise in powering fuel cells. Research findings showed DDGS's potential to produce low-cost electricity. DigitalJournal.com (9/5) LinkedInFacebookTwitterEmail this Story
