As Republican and Democratic parties prepare for national conventions this summer, campaign speeches are filled with promises about everything from health care to the economy and national security.

But a national poll suggests presumptive presidential candidates Hillary Clinton and Donald Trump may want to consider their positions on a less-talked about topic: children's health.

Greenland's glaciers are melting, but they do that every year. However, a recent computer simulation sounds the alarm about a 50 percent increase in the freshwater flux since 1990, which is too narrow a timeframe for scientific purposes, it is the target date for the original Kyoto treaty on global warming, but will be a clarion for policy makers. 

Whole Foods shoppers and other anti-science groups may not like it, but scientists have taken the first step of an ongoing-process designed to bring a valuable heirloom wheat back from the brink of extinction. 

Solar energy wants to become an alternative source to fossil fuels but no one wants to incur the much higher cost required by continued subsidies. Rather than  trying to create large solar farms, which are invariably blocked by environmental lawsuits, the move is on to go small and avoid regulations - that means on buildings, clothes, consumer electronics and wearables. This necessitates ultra-thin film, low-cost and ideally flexible solar cells without compromising the environment during production, use, or disposal.

Chronic myeloid leukemia (CML) develops through chromosomal alterations in blood-forming cells of the bone marrow and usually occurs in older persons. Around 20 percent of adults diagnosed with leukemia suffer from this type of blood cancer.

We know water is essential to life as we know it, but why? 

A paper in Proceedings of the National Academy of Sciences provides strongest evidence that proteins--the large and complex molecules that fold into particular shapes to enable biological reactions--can't fold themselves. Rather, the work of folding is done by much smaller water molecules, which surround proteins and push and pull at them to make them fold a certain way in fractions of a second, like scores of tiny origami artists folding a giant sheet of paper at blazingly fast speeds.
