A solar illusion: Coronal loops may not be what they seem

Many coronal loops—ropey strands of plasma that scientists have long thought existed in the Sun's atmosphere—may actually be optical illusions, according to a new paper that challenges prevailing assumptions of what we ...

Ocean eddies could explain Antarctic sea-ice paradox

Despite global warming and the sea-ice loss in the Arctic, the Antarctic sea-ice extent has remained largely unchanged since 1979. However, existing climate model-based simulations indicate significant sea-ice loss, contrary ...

Schools and the pandemic: Simulation model allows for safe operation

A year ago, the whole world discussed: is it irresponsible to send children to school during a pandemic, or do measures exist that can prevent corona clusters so efficiently that schools can stay open (or reopen)?

Studying the big bang with artificial intelligence

It could hardly be more complicated: tiny particles whir around wildly with extremely high energy, countless interactions occur in the tangled mess of quantum particles, and this results in a state of matter known as "quark-gluon ...
