New material for splitting water

Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen, which can then be recombined in a fuel cell to release energy. Now, a new class of materials -- halide double perovskites -- may have just the right properties to split water.

Reduction in sulfur emissions from power plants in China

Air pollution has smothered China's cities in recent decades. In response, the Chinese government has implemented measures to clean up its skies. But are those policies effective? Now scholars show that one of China's key antipollution laws is indeed working -- but unevenly, with one particular set of polluters most readily adapting to it.

Overuse of agricultural chemicals on China’s small farms harms health and environment

The size of farms in China is a key contributor to the overuse of agricultural chemicals, and as a result they may be too small to be environmentally sustainable, a new study has found.

Coral reef ‘oases’ offer glimmer of hope

Scientists have discovered small communities of corals that are flourishing against the odds while so many around the world are dying.

Primates in peril

Primates are fascinating. They are intelligent, live in complex societies and are a vital part of the ecosystem. Lemurs, lorises, galagos, tarsiers, monkeys and apes are our closest biological relatives and just like them, humans are also primates. However, while the human population spread to all corners of the earth, many of our closest relatives are under serious threat.

Orange, tea tree and eucalyptus oils sweeten diesel fumes

Waste oil from orange, tea tree and eucalyptus essential oil production mixed with diesel provides a sweet-smelling biofuel blend with comparable performance to diesel-only fuel.

Quality of diet still poor for SNAP participants

A new study finds persistent nutritional disparities within the food choices of those receiving assistance under the Supplemental Nutrition Assistance Program (SNAP) compared to those not receiving SNAP assistance.

Genetic engineering researcher: Politicians are deaf to people’s ethical concerns

A new study reports that political discussions about genetically modified foods have ignored concerns among Danes that GM foods are 'unnatural'.

Meat sensitivity spread by ticks linked to heart disease

Researchers have linked sensitivity to an allergen in red meat -- a sensitivity spread by tick bites -- with a buildup of fatty plaque in the arteries of the heart. This buildup may increase the risk of heart attacks and stroke.

New method makes weather forecasts right as rain

Meteorologists have known for some time that rainfall forecasts have flaws, as failure to take into account factors such as evaporation can affect their accuracy. Now, researchers have developed a system that improves the precision of forecasts by accounting for evaporation in rainfall estimates, particularly for locations 30 miles or more from the nearest National Weather Service radar.

Machine learning may be a game-changer for climate prediction

New research demonstrates that machine-learning techniques can be used to accurately represent clouds and their atmospheric heating and moistening, and better represent clouds in coarse resolution climate models, with the potential to narrow the range of climate prediction. This could be a major advance in accurate predictions of global warming in response to increased greenhouse gas concentrations that are essential for policy-makers (e.g. the Paris climate agreement).
