July 21, 2016 — Latitude is the main factor which determines the organic pollutant concentration in Antarctic giant petrels – emblematic species in the Antarctic and sub-Antarctic regions – according to a new ... read more

July 21, 2016 — A new way of deriving hydrogen from grass has now been developed using just sunlight and a cheap catalyst. Garden grass could become a source of cheap and clean renewable energy, scientists have ... read more

Fire Clues in Cave Dripwater

July 21, 2016 — When mineral-rich water drips from a cave's ceiling over centuries and millennia, it forms rocky cones that hold clues to the Earth's past climate. Now, researchers in Australia and the UK ... read more

A Recent Pause in Antarctic Peninsula Warming

July 20, 2016 — The rapid warming of the Antarctic Peninsula, which occurred from the early-1950s to the late 1990s, has paused. Stabilization of the ozone hole along with natural climate variability were ... read more

Oceans May Be Large, Overlooked Source of Hydrogen Gas

July 20, 2016 — Serpentinized rocks formed near fast-spreading tectonic plates under Earth's seafloor could be a large and previously overlooked source of free hydrogen gas, a new study finds. The finding could ... read more
