Air pollution reduces global life expectancy by more than one year

Specialized droplets interact with bacteria and can be analyzed using a smartphone

Researchers have come up with a new way to test food for bacterial contamination. The test is based on a novel type of liquid droplet that can bind to bacterial proteins. This interaction, which can be detected either by the naked eye or with a smartphone, could offer a much faster and cheaper alternative to existing food safety tests.

Green tea ingredient may ameliorate memory impairment, brain insulin resistance, and obesity

Federation of American Societies for Experimental Biology  A study published online in The FASEB Journal, involving mice, suggests that EGCG (epigallocatechin-3-gallate), the most abundant catechin and biologically active component in green tea, could alleviate high-fat and high-fructose (HFFD)-induced insulin resistance and cognitive impairment. Previous research pointed to the potential of EGCG to treat a variety of human diseases, yet until now, EGCG's impact on insulin resistance and cognitive deficits triggered in the brain by a Western diet remained unclear. Journal Reference: Yashi Mi, Guoyuan Qi, Rong Fan, Qinglian Qiao, Yali Sun, Yuqi Gao, Xuebo Liu. EGCG ameliorates high-fat– and high-fructose–induced cognitive defects by regulating the IRS/AKT and ERK/CREB/BDNF. The FASEB Journal, 2017; fj.201700400RR DOI: 10.1096/fj.201700400RR

Even brief maternal deprivation early in life alters adult brain function and cognition: Rat study

May 3, 2018 Indiana University-Purdue University Indianapolis School of Science When a baby is taken from its mother for even a brief period early in life, this traumatic event significantly alters the future, adult function of the brain, according to a new animal model study. These changes in the brain are similar to disturbances in brain structure and function that are found in people at risk for neuropsychiatric disorders, such as schizophrenia
