Clocking a performance of 16.32 petaflop/s, IBM's Blue Gene/Q-class supercomputer Sequoia has become the fastest supercomputer in the world according to the latest TOP500 rankings released today. Sequoia, owned by the Department of Energy and based at the Lawrence Livermore National Laboratory, has relegated Fujitsu's K to second place.  Read More

3.75 billion years from now - the nighttime sky showing the Andromeda galaxy (M31) early i...

When Galaxies Collide! It sounds like an early science fiction novel. However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31). The collision will start in about four billion years, and over the following three billion years the two spiral galaxies will coalesce into a large elliptical galaxy. Based on this data, NASA has produced a video of the upcoming collision.  Read More

Mice injected with human Epo were motivated to exercise more (Photo: Shutterstock)

If listening to Eye of The Tiger at full bore isn’t enough to get you off your backside to blast those glutes and pump those biceps anymore, then drugs might be the answer. A team of Swiss researchers has discovered that raising the levels of the hormone erythropoietin (Epo) in the brains of mice resulted in the rodents being more motivated to exercise. The discovery provides the possibility of developing a pill that can motivate people to want to exercise.  Read More

Upon completion, the E-ELT is expected to be the largest optical telescope in the world

The European Southern Observatory (ESO) council met on Monday in Garching, Germany and approved the European Extremely Large Telescope (E-ELT) program, pending the confirmation of ad referendum votes from the authorities of four member states before the next council meeting. Assuming all goes according to plan, the E-ELT is expected to begin operation early in the next decade.  Read More

Ultra smooth SLIPS (Slippery Liquid Porous Surfaces) developed at Harvard University could...

Although advances in refrigeration technology means we don’t need to defrost the freezer as often as we used to, many of us are still forced to carry out the task on a regular basis lest we find the frosty walls closing in to claim that tub of ice cream. Now a team from Harvard University has developed ultra smooth slippery surfaces that prevent ice sheets from developing by allowing even tiny drops of condensation or frost to simply slide off. As well as keeping freezers frost-free, the technology could be used to prevent ice build up on metal surfaces in wind turbines, marine vessels, and aircraft.  Read More

The study of this marine crustacean may lead to lighter and more resistant materials that ...

The mantis shrimp is a fascinating creature that has the ability to punch its prey into submission with a club that accelerates underwater at around 10,400 g. By studying the secrets behind this formidable weapon, a Californian researcher hopes to develop an innovative, hi-tech material that is one third the weight and thickness of existing body armor.  Read More

New results from CERN today would appear to confirm that last year’s findings by the OPERA experiment which appeared to suggest that neutrinos could travel faster than light were incorrect. A faulty element of the experiment’s fiber optic timing system has been cited by CERN as a likely cause for the error.  Read More

A team of researchers at the University of Texas is exploring the possibility of electrically stimulating the visual cortex of the brain to create simple images and shapes. This development could lead to a visual prosthetic device that would effectively "trick" the brain of visually impaired or blind people into seeing ... and such a device, the authors say, is only about five years away.  Read More

An illustration depicting one of the lattice-like electrodes, over top of one of the elast...

A lot of devices, such as shock absorbers, currently use elastomers to help minimize vibrations. While the malleable, yielding qualities of these materials do indeed allow them to absorb energy that would otherwise take the form of rattles and jolts, they are nonetheless passive – basically, they just sit there. Researchers from Germany’s Fraunhofer Institute for Structural Durability and System Reliability, however, are developing a new system in which elastomers actually “fight back” against vibrations.  Read More

After decades of trial and error, artificial intelligence applications that aim to understand human language are slowly starting to lose some of their brittleness. Now, a simple mathematical model developed by two psychologists at Stanford University could lead to further improvements, helping transform computers that display the mere veneer of intelligence into machines that truly understand what we are saying.  Read More
