Nanotube water doesn't freeze - even at hundreds of degrees below zero

A new form of water has been discovered by physicists in Argonne's Intense Pulsed Neutron Source (IPNS) Division. Called nanotube water, these molecules contain two hydrogen atoms and one oxygen atom but do not turn into ...

How 'the strong force' influences the gravitational wave background

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.

Possible atmospheric destruction of a potentially habitable exoplanet

Astrophysicists studying a popular exoplanet in its star's habitable zone have found that electric currents in the planet's upper atmosphere could create sufficient heating to expand the atmosphere enough that it leaves the ...
