Surge in coal pollution led to smaller newborns: study

In fresh evidence about the dangers of coal pollution, a scientist on Monday said a switch to coal-fired power in a southern US state after a nuclear accident in 1979 led to a sharp fall in birthweight, a benchmark of health.

Converting water into hydrogen more efficiently

Scientists have long been puzzled why it is easier to produce hydrogen from water in an acidic environment than in an alkaline environment. Marc Koper comes with an explanation: the reason is the electric field at the surface ...

Researchers show that enzyme function inhibits battery ageing

It has been known in biology for a long time that the excited oxygen molecule singlet oxygen is the main cause of ageing in cells. To counter this, nature uses an enzyme called superoxide dismutase to eliminate superoxide ...

Uranium from seawater factors into nuclear power

Trace amounts of uranium exist in seawater, but efforts to extract that critical ingredient for nuclear power have produced insufficient quantities to make it a viable source for those countries that lack uranium mines. A ...

Research pinpoints promise of polycrystalline perovskites

A team of scientists from the Energy Department's National Renewable Energy Laboratory (NREL) determined that surface recombination limits the performance of polycrystalline perovskite solar cells.

NREL pioneers better way to make renewable hydrogen

Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) developed a method which boosts the longevity of high-efficiency photocathodes in photoelectrochemical water-splitting devices.

Petrol taxes drop globally despite climate change: study

The average tax on petrol in 157 nations fell 13 percent from 2003 to 2015, even as the world acknowledged the need to slash greenhouse gases from fossil fuels, researchers reported Monday.

Getting a global grip on gasoline taxes

When 195 nations joined to fight climate change in the 2015 Paris Agreement, leaders hailed the occasion as "historic" and "a tremendous victory."

Stability challenge in perovskite solar cell technology

While solar cell technology is currently being used by many industrial and government entities, it remains prohibitively expensive to many individuals who would like to utilize it.. There is a need for cheaper, more efficient ...
