Speed limit set for ultrafast electrical switch

Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral. Their results could drive innovations in the tiny transistors that control the flow of electricity across silicon chips, enabling faster, more powerful computing devices.

Removing complexity layers from the universe's creation

Complicated statistical behaviour observed in complex systems such as early universe can often be understood if it is broken down into simpler ones. Two physicists, Petr Jizba (currently affiliated with the Czech Technical University in Prague), and Fabio Scardigli (now working at Kyoto University in Japan), have just published results in EPJ C pertaining to theoretical predictions of such cosmological systems' dynamics.

Researchers detect B-mode polarization in cosmic microwave background

Researchers working at the South Pole Telescope (SPT) have detected tiny fluctuations—known as B-mode polarization—in cosmic background radiation. The team describes their findings in their paper they've uploaded to the preprint server arXiv.

Researchers stop and store light for 60 seconds

A team of researchers at Germany's University of Darmstadt has succeeded in causing light to stop and then to be held in place for 60 seconds. In their paper published in the journal Physical Review Letters, the researchers describe how they achieved this feat and how their technique might be used in possible future applications.

Largest magnetic fields in the universe

Numerical simulations show for the first time the occurrence of an instability in the interior of neutron stars that can lead to gigantic magnetic fields, possibly triggering one of the most dramatic explosions observed in the Universe.

An Alien's-Eye View of Earth

Earlier this week, the visionaries who operate NASA's Cassini spacecraft released a remarkable snapshot of Earth as seen from Saturn. It got a ton of media attention, and rightly so. It is a stunning celestial view that no human being can see first-hand, but that billions of people around the world can now experience vicariously. It starkly illustrates how small we are within the universe, while simultaneously celebrating the grand things our little species is capable of. I went on cable news to

Scientists model 'extraordinary' performance of Bolt

As the world's best athletes descend on London today to take part in the Olympic Anniversary Games, a group of researchers from Mexico has provided an insight into the physics of one of the greatest athletic performances of all time.

NASA Selects Eight Physical Science Research Proposals

NASA's Physical Science Research Program will fund eight proposals to help investigate how complex fluids and macromolecules behave in microgravity. The investigations will be conducted aboard the International Space Station.

NASA Sees Enthusiastic Response to Asteroid Call for Ideas

NASA has received more than 400 responses to its request for information (RFI) on the agency's asteroid initiative, Deputy Administrator Lori Garver announced Friday.
