  • Study: Wind shows promise in supplying world's electricity demands
    Two independent groups of scientists have discovered that wind power could be used to produce all the electricity needed in the world. Katherine Marvel, a climate scientist from Lawrence Livermore National Laboratory, and colleagues found that surface winds could produce at least 400 trillion watts of power. People worldwide are using 18 trillion watts of power. Another study indicated that the wind power available at most modern wind turbines' height before the point of diminishing returns is around 80 trillion watts.

  • NASA encourages students' involvement in naming asteroid
    NASA is soliciting suggestions from students around the world to name a potentially dangerous asteroid that it plans to visit in 2016. The expedition aims to collect space rock samples that could help scientists uncover the mysteries behind the solar system's origin. "Because the samples returned by the mission will be available for study for future generations, it is possible the person who names the asteroid will grow up to study the regolith we return to Earth," said Jason Dworkin, Osiris-Rex project scientist at NASA's Goddard Space Flight Center in Greenbelt, Md. The asteroid is 1,837 feet wide and has a small chance of striking Earth in 2182, researchers say. Space.com (9/7) LinkedInFacebookTwitterEmail this Story
  • Researchers detect magma accumulation beneath Santorini volcano
    A study in the journal Nature Geoscience found magma accumulation beneath the Santorini volcano in Greece that caused the volcanic island to rise as much as 5.5 inches. The volcano erupted around 3,600 years ago and wiped out the Minoan civilization. Researchers have followed reports early this year about seismic activity beneath the volcano, which spurred worries about its possible eruption in the near future.

  • Crows can remember and differentiate human faces, study says
    A study found that wild crows are capable of remembering human faces and recalling how different individuals treated them. Researchers wore different sets of masks when they captured and fed 12 wild American crows. Brain scans indicated that the captor mask sparked activity in the crows' brain regions involved with fear, while the feeder mask triggered activity in areas associated with reward and motivation.

  • GM mosquitoes can control dengue-carrying population, trial shows
    U.K. biotech firm Oxitec reported in the journal Nature Biotechnology that its genetically modified mosquitoes successfully wiped out 80% of Aedes aegypti, the mosquito species that carries the dengue virus, at a trial site on Grand Cayman Island. Oxitec altered the DNA of the mosquitoes to produce excessive amounts of a protein that disrupts their cell machinery unless they take the antibiotic tetracycline. When male mosquitoes with the modified gene mate with wild females, their offspring will die before adulthood.

  • Cell structure produces blue hue in African fruit, study finds
    The specialized structures in the cells of the African fruit of Pollia condensata produce its metallic blue hue, not pigmentation, according to a study in the journal Proceedings of the National Academy of Sciences. Researchers discovered that the fruit's cells had walls consisted of tightly coiled cellulose strands. They also found that the varying spacings between the strands in every cell reflect light of distinct wavelengths, producing the hue. Nature (9/10) LinkedInFacebookTwitterEmail this Story

  • Galenea's schizophrenia research wins $3M grant from NIMH
    The National Institute of Mental Health awarded a $3 million grant to Galenea and a research partner at the VA Boston Healthcare System and Harvard Medical School. The goal of the five-year grant is to advance the use of electroencephalography in preclinical studies of schizophrenia drugs by identifying differences and similarities in the brain activity of humans and rodents.
