The first comprehensive genetic study of humpback whale populations in the North Pacific Ocean has identified five distinct populations - at the same time a proposal to designate North Pacific humpbacks as a single "distinct population segment" is being considered under the Endangered Species Act.

For those living with gastrointestinal disorders, such as ulcers or Crohn's disease, treatment often means quelling uncomfortable symptoms through medications or dietary changes.
Children's National researcher, Javad Nazarian, PhD, authored a new study entitled, "Comparative Multidimensional Molecular Analyses of Pediatric Diffuse Intrinsic Pontine Glioma Reveals Distinct Molecular Subtypes."
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball - a star is born.
A research team led by Professor Keon Jae Lee and Professor Yoon Sung Nam from the Department of Materials Science and Engineering at KAIST has developed the biotemplated design of flexible piezoelectric energy harvesting device, called "nanogenerator."
St. Jude Children's Research Hospital scientists have evidence that descendants of the H2N2 avian influenza A virus that killed millions worldwide in the 1950s still pose a threat to human health, particularly to those under 50.
A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region.
An analysis of patients from across the malaria endemic world suggests that a key antimalarial treatment could be improved by better dosing in young children.
