Human pluripotent stem cells, which include both human embryonic stem cells(hESCs) and adult stem cells like induced pluripotent stem cells (iPSCs), need large numbers for transplantation into patients but the process of translating their potential into effective, real-world treatments involves deciphering and resolving a host of daunting complexities, according to a new study.

The authors say they have definitively shown that the culture conditions in which stem cells are grown and mass-produced can affect their genetic stability.
Emulsifiers, which are added to processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation in mice that promotes the development of inflammatory bowel disease and metabolic syndrome, according to a new study.

The team fed mice two commonly used emulsifiers, polysorbate 80 and carboxymethylcellulsose, at doses seeking to model the broad consumption of the numerous emulsifiers that are incorporated into almost all processed foods. They observed that emulsifier consumption changed the species composition of the gut microbiota and did so in a manner that made it more pro-inflammatory. 

Gender and personality matter in how people cope with physical and mental illness, according to a paper by a Washington State University scientist and colleagues at the University of the Thai Chamber of Commerce.

Men are less affected by a single-symptom illness than women, but are more affected when more than one symptom is present. The number of symptoms doesn't change how women are affected, according to Robert Rosenman, WSU professor in the Department of Economic Sciences. Rosenman worked with Dusanee Kesavayuth and Vasileios Zikos, both at UTCC in Bangkok, Thailand, on the study.


It's hard to hide from a bat: The camouflage and mimicry techniques that animals use to avoid becoming a meal aren't much use against a predator using echolocation. But a new study shows that moths can outsmart sonar with a flick of their long tails.

The study appearing in the Proceedings of the National Academy of Sciences shows luna moths spin their trailing hindtails as they fly, confusing the sonar cries bats use to detect prey and other objects.


What started as an evolutionary protection against starvation has become a biological "bad joke" for people who need to lose weight. The human body doesn't distinguish between dieting and possible starvation, so when there is a decrease in calories consumed, human metabolism increases its energy efficiency and weight loss is resisted.


Adolescent binge drinking has been linked to a host of problems, including worse school performance, risky sexual behaviors, illicit drugs, and a greater risk of suicide. Binge drinking may also be linked to problematic eating behavior, yet little research exists. A study of the relationship between binge drinking and eating problems among Russian adolescents has found that problematic eating behaviors and attitudes are commonplace, and that binge drinking is associated with more eating problems in girls than boys.

Results will be published in the March 2015 online-only issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View.
