For people who live in the Arctic, sea ice that forms along shorelines is a vital resource that connects isolated communities and provides access to hunting and fishing grounds.
A new study by Brown University researchers found that climate…

To make an atom-sized machine, you need a quantum mechanic
Here’s a new chapter in the story of the miniaturisation of machines: researchers in a laboratory in Singapore have shown that a single atom can function as either an engine or a fridge. Such a device could be engineered into future computers…

Catastrophic outburst floods carved Greenland’s ‘Grand Canyon’
Buried a mile beneath Greenland’s thick ice sheet is a network of canyons so deep and long that the largest of these has been called Greenland’s “Grand Canyon.”
This megacanyon’s shape suggests it was carved by running water prior to…

Space laser missions map 16 years of ice sheet loss
Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years.
The results…

Gravitational waves could prove the existence of the quark-gluon plasma
Neutron stars are among the densest objects in the universe. If our Sun, with its radius of 700,000 kilometres were a neutron star, its mass would be condensed into an almost perfect sphere with a radius of around 12 kilometres.
When two neutron…

Scientists find evidence of how platinum metals form under 60 million-year-old Scottish volcano
Research carried out by scientists at Keele University, the University of Manchester and University College Dublin has shed new light on how precious metals are concentrated in igneous rocks.
The solidified remains of sub-volcanic magmatic…

Glacier Detachments: A New Hazard in a Warming World?
A startling event occurred deep in the remote interior of the United States’ largest national park.
A half-kilometer-long tongue of Alaska’s Flat Creek glacier suddenly broke off, unleashing a torrent of ice and rock that rushed 11 kilometers…

New findings suggest laws of nature not as constant as previously thought
Those looking forward to a day when science’s Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the cosmological constants is not so constant…

Big data reveals we’re running out of time to save environment and ourselves
The use of big data can help scientists’ chart not only the degradation of the environment but can be part of the solution to achieve sustainability, according to a new commentary paper.
The paper, ‘Opportunities for big data in conservation and…

New high-energy-density physics research provides insights about the universe
Atoms and molecules behave very differently at extreme temperatures and pressures. Although such extreme matter doesn’t exist naturally on the earth, it exists in abundance in the universe, especially in the deep interiors of planets and…
