Negative social cues on tobacco packaging may help smokers quit
New research published in the Journal of Consumer Affairs suggests that tobacco packaging that reminds smokers that broad societal 'others' disapprove of the activity can trigger feelings of self-consciousness, which in turn reduces smoking intentions. (2018-11-21)

Mom's teeth tell her history of giving birth and raising babies in Asian black bears
Scientists from four Japanese institutions including Tokyo University of Agriculture and Technology (TUAT) have discovered that width of surface layers coating tooth's roots correlates with reproductive histories of female Asian black bears. When a female bear raised cubs, the layers of her teeth were much narrower compared to those when she was not. Thus, measuring layer width of female bears' teeth can be a useful index for their reproductive histories. (2018-11-19)

For the first time, a team of astronomers has observed several pairs of galaxies in the final stages of merging together into single, larger galaxies. Peering through thick walls of gas and dust surrounding the merging galaxies' messy cores, the research team captured pairs of supermassive black holes -- each of which once occupied the center of one of the two original smaller galaxies -- drawing closer together before they coalescence into one giant black hole.

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)

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. (2018-10-18)

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.
