At the center of a galaxy cluster, 1 billion light years from Earth, a voracious, supermassive black hole is preparing for a chilly feast.

For the first time, astronomers have detected billowy clouds of cold, clumpy gas streaming toward a black hole, at the center of a massive galaxy cluster. The clouds are traveling at speeds of up to 355 kilometers per second -- that's almost 800,000 miles per hour -- and may be only 150 light years away from its edge, almost certain to fall into the black hole, feeding its bottomless well. The observations, which will be published in the journal Nature, represent the first direct evidence to support the hypothesis that black holes feed on clouds of cold gas.

A research team from Oxford University have shown how different colours of light could affect our ability to sleep.

The researchers, led by Dr Stuart Peirson from Oxford's Sleep and Circadian Neuroscience Institute were aiming to understand why exposing mice to bright light caused two - physically incompatible - responses.

Dr Peirson explained: 'When we expose mice to light during the night, it causes them to fall asleep. Yet, at the same time, it also increases levels of corticosterone, a stress hormone produced by the adrenal gland that causes arousal - wakefulness. We wanted to understand how these two effects were related and how they were linked to a blue light-sensitive pigment called melanopsin, known to play a key role in setting our body clock.'

New research combining eight large child care studies reveals that preschools prepare children to succeed academically when teachers provide higher quality instruction.

Margaret Burchinal, senior scientist at the Frank Porter Graham Child Development Institute at the University of North Carolina at Chapel Hill, led a research team whose findings have groundbreaking implications for publicly-funded early care and education. They found as the overall quality of instruction in preschool classrooms increases, children experience better outcomes across a range of skills, but the needle only moves on language and reading skills when instructional quality is at or above a threshold.

Researchers at the National Institute of Neurological Disorders and Stroke have discovered that boosting the transport of mitochondria along neuronal axons enhances the ability of mouse nerve cells to repair themselves after injury. The study, "Facilitation of axon regeneration by enhancing mitochondrial transport and rescuing energy deficits," which has been published in The Journal of Cell Biology, suggests potential new strategies to stimulate the regrowth of human neurons damaged by injury or disease.

June 7, 2016 - Adding to previous evidence, a study based on a statewide cancer database shows no increase in cancer risk in patients undergoing spinal fusion surgery with the bone-promoting growth factor recombinant human bone morphogenetic protein (rhBMP). The study appears in Spine, published by Wolters Kluwer.

The International Union of Pure and Applied Chemistry (IUPAC) opened a public comment period Wednesday for the recommended names of elements 115, 117 and 118.

Lawrence Livermore National Laboratory and the Joint Institute for Nuclear Research in Dubna, Russia (JINR) were credited late last year for discovering elements 115 and 118. LLNL, JINR, Oak Ridge National Laboratory (ORNL), Vanderbilt University and the University of Nevada, Las Vegas were credited with the discovery of element 117.

Moscovium (Mc) is provisionally recommended for element 115 in recognition of the Moscow region and honoring the ancient Russian land that is home to JINR. Moscow is the capital of the region.
