Rare particles give clue to ancient Earth
(Phys.org) —Semi-precious minerals found in a bucket of sand from an island nation have cracked open a clue to the drifting movements and break-up of ancient Earth's massive continental plates.
Fragments of continents hidden under lava in the Indian Ocean
The islands Reunion and Mauritius, both well-known tourist destinations, are hiding a micro-continent, which has now been discovered. The continent fragment known as Mauritia detached about 60 million years ...
Why 'singing' sand dunes hum certain notes
What does Elvis Presley have in common with a sand dune? No, it's not that people sometimes spot both in the vicinity of Las Vegas. Instead, some sand dunes, like The King, can sing. And new research looking ...
Learning from sand castles to build future chips
In the United States, data centers already consume two percent of the electricity available with consumption doubling every five years. In theory, at this rate, a supercomputer in the year 2050 will require ...
Oil spill causes massive harm to microscopic creatures
(Phys.org) -- Oiled seabirds and turtles may have been the dominant images of the Deepwater Horizon oil spill, but new research indicates there was also massive harm to microscopic creatures in coastal sands, lasting months ...
X-rays create a window on glass formation: First ever visualization of how powder becomes molten glass
Scientists have for the first time visualised the transformation of powder mixtures into molten glass. A better understanding of this process will make it possible to produce high quality glass at lower temperatures, ...
Transverse instability of megaripples
Aeolian ripples, which form regular patterns on sand beaches and desert floors, indicate the fundamental instability of flat sand surfaces under the wind-induced transport of sand grains.
A 'melted' moon makes for bad future landing sites
The miniature radio frequency (min-RF) radar instrument aboard the Lunar Reconnaissance Orbiter (LRO) is revealing some interesting things about how impact melts form around craters on the Moon. Impacts produce ...
Oil more easily converted into petrol thanks to a smart observational technique
Catalysts are needed to convert crude oil into petrol and other fuels. However, a technique for accurately determining how well individual catalyst particles work or continue to work was not available.
Earth's oldest fossils boost hopes for life on Mars
(PhysOrg.com) -- Microfossils found in Australia show that more than 3.4 billion years ago, bacteria thrived on an Earth that had no oxygen, a finding that boosts hopes life has existed on Mars, a study published ...
Researchers discover ancient symbiosis between animals, bacteria
Marine shallow water sandy bottoms on the surface appear desert-like and empty, but in the interstitial space between the sand grains a diverse fauna flourishes. In addition to bacteria and protozoa numerous ...
Even Canadian rocks are different
Canadians have always seen themselves as separate and distinct from their American neighbours to the south, and now they have geological proof.
