Artificial intelligence bot trained to recognize galaxies
Researchers have taught an artificial intelligence program used to recognize faces on Facebook to identify galaxies in deep space. The result is an AI bot named ClaRAN that scans images taken by radio telescopes.

More black South Africans are donating blood
Before 2005, blood donations from black South Africans were used selectively and often discarded, due to the higher recorded rates of HIV infection in the black population. In October 2005, SANBS became the first blood service in the world to implement individual donation nucleic acid testing nationawide. An analysis of ten years of data shows a substantial increase in the number and proportion of donations from black South Africans after the implementation of NAT. (2018-10-31)

Astronomers spot signs of supermassive black hole mergers
New research, published today in the journal Monthly Notices of the Royal Astronomical Society, has found evidence for a large number of double supermassive black holes, likely precursors of gigantic black hole merging events. This confirms the current understanding of cosmological evolution -- that galaxies and their associated black holes merge over time, forming bigger and bigger galaxies and black holes. (2018-10-23)

Gravitational waves could shed light on dark matter
Black holes colliding, gravitational waves riding through space-time - and a huge instrument that allows scientists to investigate the fabric of the universe. This could soon become reality when the Laser Interferometer Space Antenna (LISA) takes up operations. Researchers from the University of Zurich have now found that LISA could also shed light on the elusive dark matter particle. (2018-10-22)

Mystery of how black widow spiders create steel-strength silk webs further unravelled
Northwestern University and San Diego State University researchers have better unraveled the complex process of how black widow spiders transform proteins into steel-strength fibers. This knowledge promises to aid scientists in creating equally strong synthetic materials. Utilizing state-of-the-art techniques, the research team was able to more closely see inside the protein gland where the silk fibers originate, revealing a more complex, hierarchical protein assembly. The researchers' 'modified micelles theory' concludes that spider silk proteins start out as complex, compound micelles. (2018-10-22)

Study finds racial disparities in student debt increase after young people leave college
Racial disparities in student debt between blacks and whites may perpetuate the racial wealth gap according to a study in the online first edition of Sociology of Race and Ethnicity. The study is the first to evaluate how racial disparities in student debt change over one's life course -- from when young people first graduate or leave college in their early 20s to over the next 10 years, as they enter the job market, start families and transition into adulthood.

Genetic behavior reveals cause of death in poplars essential to ecosystems, industry
Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species' inability to resist a pervasive and deadly disease. Their finding, published in the Proceedings of the National Academy of Sciences, could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.

Cooling effect of preindustrial fires on climate underestimated
A new study, ;Reassessment of Pre-Industrial Fire Emissions Strongly Affects Anthropogenic Aerosol Forcing,' by a Cornell University postdoctoral researcher, published in Nature Communications, finds that emissions from fire activity were significantly greater in the preindustrial era, which began around 1750, than previously thought. As a result, scientists have underestimated the cooling effect the aerosol particles produced by these fires had on the past climate. (2018-10-03)

HAWC: Microquasar SS 433 reveals the nature of the brightest lanterns of the universe
They shine even from billions of light years away. Intriguing and enigmatic, quasars are loath to uncover their secrets. Fortunately, we can find out more about them by looking at their star counterparts -- microquasars. Many years of observation of the microquasar SS 433, carried out in the HAWC observatory, have made it possible to identify, for the first time, spectacular details of the processes responsible for the production of high-energy radiation.

Diet rich in fried and processed foods linked to increased hypertension in black Americans
New findings suggest that diet is a major contributor for the increased risk of hypertension in black compared to white Americans. The results, published in the Journal of the American Medical Association, are part of the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study, which looks at the incidence of stroke in approximately 30,000 individuals. The study is funded by the National Institute of Neurological Disorders and Stroke (NINDS), a part of the National Institutes of Health. (2018-10-03)

Black holes ruled out as universe's missing dark matter
If dark matter consists of a plethora of primordial black holes, then their gravitational lensing -- magnifying and brightening distant objects -- should be detectable. UC Berkeley physicists analyzed 740 known supernovas to find the handful that should have been magnified and brightened by black holes, and found none. This puts a strong upper limit, 40, on the percent of dark matter that can consist of black holes, and suggests that none of it is. (2018-10-02)

Gaia spots stars flying between galaxies
A team of astronomers using the latest set of data from ESA's Gaia mission to look for high-velocity stars being kicked out of the Milky Way were surprised to find stars instead sprinting inwards -- perhaps from another galaxy. The study is published in the journal Monthly Notices of the Royal Astronomical Society. (2018-10-02)

Southern diet is top factor associated with higher risk of high blood pressure among black adults
High blood pressure is widespread among black adults in the United States and it is a major contributor to disparities in life expectancy, although reasons for this increased hypertension risk are unknown. Researchers examined 12 factors and their association with the development of hypertension among 6,900 black and white adults who didn't have hypertension when they entered the study in 2003-2007 and who were followed-up nine years later. (2018-10-02)

A mechanism of color pattern formation in ladybird beetles
Many ladybirds have attractive color patterns consisting of black and red. A research team led by Professor Teruyuki Niimi at the National Institute for Basic Biology in Japan focused on the multicolored Asian ladybird beetle Harmonia axyridis (also known as the harlequin ladybird), which lives mainly in Siberia and East Asia, and shows >200 color patterns within a species. The team has identified a single gene that regulates such highly diverse ladybird color patterns. (2018-09-26)
