Black hole spin cranks-up radio volume
Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets. (2018-01-12)

Mixing state of black carbon from biomass burning differs in different combustion phase
Black carbon aerosols in the atmosphere provide 'seed' for haze formation in urban/regional scale.In northern China, open biomass burning, such as straw burning after harvesting, is one of important sources of refractory black carbon (rBC). In order to better characterize the aging process of rBC, combustion lab experiments have been conducted to simulate and investigate the rBC emission and mixing state characteristics under different combustion conditions. (2017-12-20)

New measurements to guide radiation therapy
When ionizing radiation passes through living tissue, it interacts with molecules present in the cells, stripping away electrons and producing charged species known as ions. The electrons produced by this process, known as secondary electrons, can themselves go on to wreak further havoc, causing even more dramatic changes. This week in The Journal of Chemical Physics, investigators report studies of the impact of secondary electrons on a model of DNA. (2017-12-19)

UVB radiation influences behavior of sticklebacks
Fish cannot see ultraviolet B rays but still change their behavior when they grow up under increased UVB intensity. According to studies by biologists at the University of Bonn on three-spined sticklebacks (Gasterosteus aculeatus), increased UVB leads to a smaller body size and more risk-seeking behavior when faced with predators. Climate change is likely to increase UVB intensity, possibly with consequences for ecosystems and fish farming. (2017-12-13)
