Experimental fingerprint test can distinguish between those who have taken or handled cocaine
University of Surrey

An experimental fingerprint detection approach can identify traces of cocaine on human skin, even after someone has washed their hands - and the test is also smart enough to tell whether an individual has actually consumed the class A drug, or simply handled it.

Antioxidant Reverses BPA-Induced Fertility Damage in Worms
Harvard Medical School

At a glance: Treatment with a naturally occurring antioxidant, CoQ10, restores many aspects of fertility in C. elegans worms following exposure to BPA. Findings offer possible path toward undoing BPA-induced reproductive harms in people. Although CoQ10 is available over the counter, it is not yet clear whether the compound could improve human fertility or do so safely.

Hemp ‘goes hot’ due to genetics, not growing conditions
Cornell University

As the hemp industry grows, producers face the risk of cultivating a crop that can become unusable – and illegal – if it develops too much of the psychoactive chemical THC. Cornell University researchers have determined that a hemp plant’s propensity to ‘go hot’ – become too high in THC – is determined by genetics, not as a stress response to growing conditions, contrary to popular belief.

The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows. The findings, published today in the journal Nature Materials, show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.

Scientists for the first time have developed a single molecule that can absorb sunlight efficiently and also act as a catalyst to transform solar energy into hydrogen, a clean alternative to fuel for things like gas-powered vehicles. This new molecule collects energy from the entire visible spectrum, and can harness more than 50% more solar energy than current solar cells can. The finding could help humans transition away from fossil fuels and toward energy sources that do not contribute to climate change.
