Double or nothing: Astronomers rethink quasar environment

http://ift.tt/eA8V8J Astronomers have identified nearly 200 'protoclusters,' the progenitors of galaxy clusters, in the early Universe, about 12 billion years ago, about ten times more than previously known. They also found that quasars don't tend to reside in protoclusters; but if there is one quasar in a protocluster, there is likely a second nearby. This result raises doubts about the relation between protoclusters and quasars.

Lack of water is key stressor for urban trees

http://ift.tt/eA8V8J A recent study finds that urban trees can survive increased heat and insect pests fairly well -- unless they are thirsty. Insufficient water not only harms trees, but allows other problems to have an outsized effect on trees in urban environments.

Scientists find treasure trove of 110 genes linked to breast cancer

http://ift.tt/eA8V8J Scientists have linked 110 genes to an increased risk of breast cancer in the most comprehensive study ever to unpick the genetics of the disease. Their study used a pioneering genetic technique to analyse maps of DNA regions linked to an inherited risk of breast cancer and identify the actual genes involved in raising a woman's risk. Researchers also linked 32 of the new genes to the length of time women survived breast cancer.

Color-changing hogfish 'sees' with its skin

http://ift.tt/eA8V8J The hogfish can go from white to reddish in milliseconds as it adjusts to shifting conditions in the ocean. Scientists have long suspected that animals with quick-changing colors don't just rely on their eyes to tune their appearance to their surroundings -- they also sense light with their skin. But exactly how remains a mystery. A study reveals that hogfish skin senses light differently from eyes.
