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'
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

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
