For students of color, online racism leads to real-world mental health challenges
For college students of color who encounter online racism, the effect of racialized aggressions and assaults reaches far beyond any single social media feed and can lead to real and significant mental health impacts - even more significant than in-person experiences of racial discrimination, according to a recently published study from researchers at UConn and Boston College.

Researchers offer new technology for liquid-crystal displays
An international research team from Russia, France, and Germany has proposed a new method for orienting liquid crystals. It could be used to increase the viewing angle of liquid-crystal displays. The researchers have found that by merely adding one methylene group to the side chain of the polymer, they could switch the LC orientation, which is crucial for most applications of liquid crystals, including LCDs. The researchers expect this technology to be considerably simpler and cheaper than other multidomain approaches that are currently used. (2018-05-11)
