  • US children now draw female scientists more than ever
    When drawing scientists, US children now depict female scientists more often than ever, according to new research, which analyzed five decades of 'Draw-A-Scientist' studies conducted since the 1960s. This change suggests that children's stereotypes linking science with men have weakened over time, said the researchers, consistent with more women becoming... Read more »
  • Chronic fatigue syndrome possibly explained by lower levels of key thyroid hormones
    A new study reveals that chronic fatigue syndrome, a debilitating condition with unknown causes, can be explained by lower thyroid levels -- but may be distinct from thyroidal disease. This can be seen as a first step to finding a treatment for a common illness for which diagnosis is hard... Read more »
  • Rain or snow? Humidity, location can make all the difference, new map shows
    Researchers have created a map of the Northern Hemisphere showing how location and humidity can affect precipitation, illustrating wide variability in how and why different areas receive snow or rain.... Read more »
  • Discovered mode of drinking in mosquitoes carries biomedical implications
    Mosquitoes may have a reputation for being one of the world's most intractable pests, but they're actually quite tiny and fragile. So when an international team of scientists wanted to observe the underlying mechanisms of how the insects feed, they had to get creative.... Read more »
  • Trial shows safety of drugs for irregular heartbeat patients undergoing treatment
    A trial has found that two types of blood thinning drugs are safe to use in patients with an irregular heartbeat when they are undergoing surgery aimed at stopping the condition.... Read more »
  • Physicists made crystal lattice from polaritons
    (ITMO University) An international research team produced an analog of a solid-body crystal lattice from hybrid photon-electron quasiparticles -- polaritons. In the resulting polariton lattice, certain particles' energy does not depend on their speed. At the same time, the lattice's geometry, particle concentration and polarization properties can still be modified.... Read more »
  • Researchers create new low-cost, sustainable material for reducing air and water pollution
    (Frontiers) A new class of hybrid materials shows promise as an affordable and sustainable product for reducing particulate matter in air and organic pollutants in wastewater. The material, produced inexpensively from an industrial waste by-product and naturally abundant polymers, performed more efficiently than activated carbon, the current gold standard.... Read more »
  • USTC reports diamond ring architecture of a protein complex
    (University of Science and Technology of China) Professor CAI Gang from USTC and Professor Jacques Côté's team reports the 4.7 Å structure of the yeast NuA4/TIP60 complex, which elucidates the detailed architecture and molecular interactions between NuA4 subunits. A related study is published online in Nature Communications on March 19.... Read more »
  • A star disturbed the comets of the solar system in prehistory
    (FECYT - Spanish Foundation for Science and Technology) About 70,000 years ago, when the human species was already on Earth, a small reddish star approached our solar system and gravitationally disturbed comets and asteroids. Astronomers from the Complutense University of Madrid and the University of Cambridge have verified that the... Read more »
  • Researchers create microlaser that flies along hollow optical fiber
    (The Optical Society) For the first time, researchers have optically trapped and propelled a particle-based laser for centimeters inside an optical fiber.... Read more »
