Flare from black hole surprises astronomers
A bright flare has been observed emanating from Sagittarius A*, the black hole at the center of the Milky Way, and scientists are trying to figure out what caused it. "The black hole was so bright I at first mistook it for the star S0-2, because I had never seen Sgr A* that bright," said Tuan Do, author of a study set for publication in The Astrophysical Journal Letters.

Green turtles are likely mistaking pieces of plastic for their normal diet of seagrass, according to a study published in Scientific Reports that examined the stomach contents of dead turtles found on Cyprus beaches. "Sea turtles are primarily visual predators -- able to choose foods by size and shape -- and in this study we found strong evidence that green turtles favor plastic of certain sizes, shapes and colors," said Emily Duncan, one of the study's authors.

Autism-associated genes identified
A study in the journal Cell showed that 69 genes were tied to a higher likelihood of autism spectrum disorder, 16 of which are newly linked to ASD, while about 600 other genes may up the odds of ASD according to their interaction with ASD-associated genes. Researchers also found the rare and highly damaging gene variants were significantly elevated among parents of children with ASD, who mostly pass the genes to affected but not unaffected children.

Sea craft to study volcano's vents to prepare for space missions
A NASA-funded craft called the In-situ Vent Analysis Divebot for Exobiology Research will study hydrothermal vents at the Axial Seamount underwater volcano off Oregon's coast to prepare for the eventual exploration of water-filled moons in the solar system. InVADER, which will spend a year at the volcano, will practice using its technologies in the deep sea and gather measurements and samples from the vents.

Scientists, put what you know in terms policymakers will understand
Scientists can expand their reach and most effectively influence policy if they collaborate and communicate well, write Hannah Safford and Austin Brown of the UC Davis Policy Institute for Energy, Environment, and the Economy. Among their six recommendations, Safford and Brown encourage scientists to boil down lengthy academic articles into briefs or opinion pieces and focus on making suggestions that are feasible and specific.
