Study: 'Warm ice age' changed climate cycles

Approximately 700,000 years ago, a "warm ice age" permanently changed the climate cycles on Earth. Contemporaneous with this exceptionally warm and moist period, the polar glaciers greatly expanded. A European research team ...

Supercomputing simulations spot electron orbital signatures

No one will ever be able to see a purely mathematical construct such as a perfect sphere. But now, scientists using supercomputer simulations and atomic resolution microscopes have imaged the signatures of electron orbitals, ...
