Ancient trapped water explains Earth's first ice age
Tiny bubbles of water found in quartz grains in Australia may hold the key to understanding what caused the Earth's first ice age, say ...
Which qubit my dear? New method to distinguish between neighboring quantum bits
Researchers have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a ...
Mars had oxygen-rich atmosphere 4,000 million years ago
Differences between Martian meteorites and rocks examined by a NASA rover can be explained if Mars had an oxygen-rich atmosphere 4,000 million years ...
Saving energy in subway stations
As well as being the backbone of urban public transport systems, subways are also major consumers of energy. For example, the entire underground ...
Noble gases hitch a ride on hydrous minerals
The six noble gases do not normally dissolve into minerals, leaving earth scientists to wonder how they are recycled back into the Earth.
Long distance calls by sugar molecules
All our cells wear a coat of sugar molecules, so-called glycans. Researchers have now discovered that glycans rearrange water molecules over long ...
Chemical probe confirms that body makes its own rotten egg gas, H2S, to benefit health
A new study confirms directly what scientists previously knew only indirectly -- that poisonous "rotten egg" gas hydrogen sulfide is generated by the ...
