Metals used in high-tech products face future supply risks
In a new paper, a team of Yale researchers assesses the "criticality" of all 62 metals on the Periodic Table of Elements, providing key insights into which materials might become more difficult to find in ...
Eiffel Tower goes dark in symbolic move for Earth Hour
The Eiffel Tower has gone dark briefly to mark Earth Hour, the campaign to raise awareness about climate change.
Lights out in Australia as Earth Hour kicks off

Explosions of Jupiter's aurora linked to extraordinary planet-moon interaction
On Earth, bursts of particles spewed by the Sun spark shimmering auroras, like the Northern Lights, that briefly dance at our planet's poles. But, on Jupiter, there's an auroral glow all the time, and new ...
NASA asteroid hunter spacecraft data available to public
Millions of images of celestial objects, including asteroids, observed by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data ...
A stiff new layer in Earth's mantle: Why the planet's conveyor belt hangs up 930 miles deep
By crushing minerals between diamonds, a University of Utah study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may ...
World's largest asteroid impacts found in central Australia
A 400 kilometre-wide impact zone from a huge meteorite that broke in two moments before it slammed into the Earth has been found in Central Australia.
Colorful life-form catalog will help discern if we are alone
While looking for life on planets beyond our own solar system, a group of international scientists has created a colorful catalog containing reflection signatures of Earth life forms that might be found on ...
Ocean pipes 'not cool,' would end up warming climate
To combat global climate change caused by greenhouse gases, alternative energy sources and other types of environmental recourse actions are needed. There are a variety of proposals that involve using vertical ...

Solar eclipses offer opportunity for science, as well as for awe and wonder
A solar eclipse is a rare event to witness first hand. A wag might add that once you've factored in the British weather they're rarer still, however observers in some areas of the UK managed to peer through ...
Researchers study fluctuations in solar radiation
The Sun is the Earth's principal source of energy and climate driver. Yet sometimes it sends more light to the Earth than other times. Astronomers working with Natalie Krivova at the Max Planck Institute ...
Japan space scientists make wireless energy breakthrough
