A Perfect Solar Storm (Video)

On 23 July 2012, two eruptions on the sun known as coronal mass ejections (CMEs) burst from an active patch of sunspots on the far side of the sun, which is monitored by a probe that circles the sun ahead of Earth in the same orbit. Emerging about 15 minutes apart, the CMEs quickly merged into one shock wave of charged particles that washed over the probe’s sensors just 18.6 hours later

ScienceShot: A New Type of 'Quasicrystal'

ScienceShot: A New Type of 'Quasicrystal'

In 1982, Daniel Shechtman, an Israeli materials scientist, was first to spot a new type of irregular crystal, known as a quasicrystal. Unlike conventional crystals that have a regular repeating pattern to their member atoms, in quasicrystals the pattern is ordered but doesn’t repeat. Since Shechtman’s discovery, hundreds of quasicrystals have been discovered, most of which are alloys of two or three metals

Warning: Your open-plan office can make you ill

Don’t blame other commuters if you catch a cold this winter: blame the people who designed your office. According to a study, workplace layout has a surprising effect on rates of sick leave. After crunching the numbers, the researchers found a 'significant excess risk' of short sick-leave spells in three types of open-plan office

Usain Bolt's superhuman speed would give him the power of flight on Saturn's moon Titan

We all know Usain Bolt is one of the fastest people on Earth. Now, students have shown his superhuman speeds would actually allow him to fly like a bird on one of Saturn’s moons while wearing a wingsuit. The world-record holding sprinter has reached top speeds of 12.27 meters per second, which would be fast enough for him to take off on Titan while wearing a regular wingsuit. Theoretically, the Olympic athlete would then be able to soar above the planet – without any need for propulsion

Find Along Chilean Highway Suggests Mass Stranding of Whales Millions of Years Ago

In 2010, workers widening a remote stretch of highway near the northwestern coast of Chile uncovered a trove of fossils, including the skeletons of at least 30 large baleen whales. The fossils—which may be up to 9 million years old—are the first definitive examples of ancient mass strandings of whales, according to a new study
