Research from the University of Rochester finds that caring for others dips during adolescence. But when young people feel supported from their social circles, their concern for others rebound.

A product called the OFF! Clip-On repellent device could be an effective tool for preventing bites from the Aedes aegypti mosquito, the primary vector of Zika, chikungunya, dengue, and yellow fever, though DEET, a permethrin or even good old-fashioned DDT will also do the trick, unless you are a Joe Mercola or SourceWatch reader and think science is a vast, right-wing conspiracy out to give you cancer. 

A genome-wide association study has identified genetic variants associated with being a morning person. The authors identified 15 locations in DNA (loci) associated with "morningness."

It has no wheels or legs or anything to help itself along, and yet it is able to move and to move quite fast. In terms of mobility, the snake is a masterpiece of engineering, and it is no coincidence that it should be studied to uncover the physics underlying its locomotion. Giancarlo Cicconofri, SISSA research fellow, and Antonio DeSimone, SISSA professor and head of MathLab, the School's laboratory for mathematical modelling and scientific computing, have developed a mathematical model to describe in detail slithering, one of the characteristic ways in which snakes move by propagating lateral undulations along the body, and described in their model as "snake in a tube".

An ensemble consisting of a binary mixture of particles of equal size can partition itself into its component fractions - provided that the two species differ in their diffusion constants.

CHICAGO-- American grocery shoppers face an array of front of pack (FOP) nutrition and health claims when making food selections. But relying on the front of pack (FOP) claims to determine the nutrition quality of the food may not be a consumer's best option. In the January issue of the Journal of Food Science study, published by the Institute of Food Technologists (IFT), researchers from The Ohio State University and Saint Joseph's University, Philadelphia examined and analyzed front of pack nutrition claims on more than 2,200 breakfast cereal and prepared meals released for sale between 2006 and 2010. What they found was that no type or number of front of pack claims could distinguish "healthy" foods.
