The peak of the hurricane season – why now?

Although the Atlantic hurricane season officially began on June 1st, we're now entering the "season within the season" - a roughly eight-week period that is often the most active and dangerous time for tropical cyclone activity.

Breaking metamaterial symmetry with reflected light

Optical activity—rotation of the polarization of light—is well known to occur within materials that differ from their mirror image. But what happens if this symmetry is broken by the direction of illumination rather than ...

Researchers show new Ice Age may begin by 2030

The arrival of intense cold similar to the weather that raged during the "Little Ice Age", which froze the world during the 17th century and in the beginning of the 18th century, is expected in the years 2030 to 2040. These ...

Irregular heartbeat of the Sun driven by double dynamo

A new model of the Sun's solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun's 11-year heartbeat. The model draws on dynamo effects in two layers of the Sun, one close to the surface ...

Using meteorite impacts to study seismic waves on Mars

(Phys.org)—Earth scientist Nick Teanby with the University of Bristol in the U.K. has come up with a novel way to measure seismic waves traveling through the under-surface of Mars—use data from meteorite impacts. In his ...

Can sound help us detect 'earthquakes' on Venus?

Detecting an "earthquake" on Venus would seem to be an impossible task. The planet's surface is a hostile zone of crushing pressure and scorching temperatures—about 874 degrees F, hot enough to melt lead—that would destroy ...

Seismic study aims to map Earth's interior in 3-D

When a 7.9-magnitude earthquake struck central China's Sichuan province in 2008, seismic waves rippled through the region, toppling apartment houses in the city of Chengdu and swaying office buildings 1,000 miles away in ...
