Dark Matter May Be Lurking at Heart of the Sun
The latest study, led by Dr Stephen West from the Department of Physics at Royal Holloway, looks at the possible effects of dark matter on the properties of the sun, if these elusive particles become trapped at its centre. “Dark matter makes up more than 80 per cent of the total mass of the universe. [...]

Spirit Rover may not live through bitter Martian winter
NASA’s Opportunity and Spirit rovers touched down on Mars in 2004 for a planned 90-day tour; six years and a few serious snags later, the latter of the two is facing its death of cold. Since March 22, 2010, Spirit’s been slumbering on the surface — stuck and unable to generate enough power to communicate [...]

What Would Happen If the Earth Stopped Spinning?
“The following is not a futuristic scenario. It is not science fiction. It is a demonstration of…an extremely* unlikely, yet intellectually fascinating query: What would happen if the earth stopped spinning?” SPOILER: Our continents become one. If that spoiler wasn’t enough, the slightly longer explanation is that, without centrifugal force, the ocean water near the [...]

First full-face transplant completed in France: tear ducts, eyelids, and all
Doctors carried out the 12-hour operation June 26 and 27 on a patient — identified only as “Jerome” — afflicted with a face-disfiguring genetic disorder. The head surgeon, Laurent Lantieri, described the surgery as a world first because it included a difficult and unprecedented transplant of tear ducts and eyelids. A similar procedure carried out [...]

This Space Nuke Explosion Was the Ultimate Firecracker
In 1962, the US government thought it might be a good idea to send a hydrogen bomb hundreds of miles into the air and detonate it. Just, you know, to see what happened. Decades later, now you can too. The recently declassified image was collected by Peter Kuran for his titillatingly titled documentary Nukes In [...]

Planetary Scientists Solve 40-Year-Old Mysteries of Mars’ Northern Ice Cap
Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars — a chasm larger than the Grand Canyon and a series of spiral troughs — solving a pair of mysteries dating back four decades while finding new evidence of climate change on Mars. In a pair of papers to [...]

Quantum Mechanics Reveals New Details of Deep Earth
Scientists have used quantum mechanics to reveal that the most common mineral on Earth is relatively uncommon deep within the planet. Using several of the largest supercomputers in the nation, a team of physicists led by Ohio State University has been able to simulate the behavior of silica in a high-temperature, high-pressure form that is [...]

Our Universe at Home Within a Larger Universe?
Could our universe be located within the interior of a wormhole which itself is part of a black hole that lies within a much larger universe? Such a scenario in which the universe is born from inside a wormhole (also called an Einstein-Rosen Bridge) is suggested in a paper from Indiana University theoretical physicist Nikodem [...]

Chilean Earthquake Results To Shorter Days
Aside from the tsunami warning that spread across the globe after the Chile earthquake, another effect of it is the 66.6 exajoules set free by the catastrophe. According to the National Aeronautics and Space Administration’s (NASA) Jet Propulsion Laboratory, days will now be shorter because of the “quake’s hit shifted the Earth’s axis by three [...]

LHC Enters World Record
CERN—the European Organization for Nuclear Research—announced that the Large Hadron Collider (LHC) became the new world’s highest energy particle accelerator after being pushed protons to 1.18 TeV (trillion electron volts). It surpasses even the previous record of 0.98 TeV, which was held by Fermilab’s Tevatron. The LHC first fired up in September 2008, but scientists [...]
