Thousands of tons of e-waste is shipped illegally to Nigeria inside used vehicles
|
A study into used electrical and electronic equipment sent to Nigeria, mostly from Europe, reveals a continuing 'severe problem' of non-compliance with rules governing such shipments. Of roughly 60,000 metric tons sent from other countries in 2015 and 2016, at least 15,400 tons was non-functioning e-waste, exports/imports of which are illegal.Almost 70 percent -- 41,500 tons -- arrived inside vehicles destined for Nigeria's secondhand auto market, thus avoiding normal inspections.

Scientists identify unique binding mechanism of antifreeze molecule
|
Antifreeze glycoproteins (AFGPs), produced by polar fishes, are known as the inhibitor of ice growing while its mechanism has remained a mystery. Using molecular simulations, scientists have identified a unique molecular binding mechanism that helps keep non-mammalian creatures in sub-zero temperatures from freezing. The finding has potential future applications for better preserving food and biological tissue under extreme temperatures.

An eye toward regeneration
|
UNLV scientist Kelly Tseng, Ph.D. and her team have found that frog embryos can fully regrow their eyes after injuries, a breakthrough that may lead one day to the ability to orchestrate tissue regeneration in humans.

New research: Eyes of adolescents could reveal risk of cardiovascular disease
|
in adolescence could be an indicator of future cardiovascular disease risk. Researchers at The Westmead Institute for Medical Research found that adolescents with poorer scores in the social and mental well-being domains of HRQoL have structural changes in their retinal blood vessels that could be associated with an increased risk of cardiovascular disease in later life.
