Watching crystals 'heal' themselves: Novel way to remove defects in materials

Physicists have succeeded in creating a defect in the structure of a single-layer crystal by simply inserting an extra particle, and then watching as the crystal "heals" itself.

Physics Nobel Prize poll: Quantum experiments and particle discoveries are the top picks

For the past month the Joint Quantum Institute (JQI) has sponsored a website allowing visitors to vote for the topic they believe will capture this year's Nobel Prize for physics. The site offered 14 Nobel-worthy topics and some representative names to go with each topic. A total of 350 votes were cast in the JQI poll, and the results are enumerated below.

NASA Hosts Oct. 4 Teleconference About Mars Curiosity Rover Progress

NASA will host a media teleconference at 11 a.m. PDT (2 p.m. EDT) Thursday, Oct. 4, to provide a status update on the Curiosity rover's mission to Mars' Gale Crater.

NASA Offers Opportunities for Biological Research on Space Station

NASA invites scientists from around the country to submit proposals to perform biological research aboard the International Space Station.

You are getting sleeeeeeepy….. | Cosmic Variance

Ikeguchi Laboratories has posted one of the most fantastic “physics in action” videos I’ve seen in a long time:

Physicists reveal first images of Landau levels

Physicists have directly imaged Landau Levels – the quantum levels that determine electron behaviour in a strong magnetic field – for the first time since they were theoretically conceived of by Nobel prize winner Lev Landau in 1930.

Nano-hillocks: Of mountains and craters

In the field of nanotechnology, electrically-charged particles are frequently used as tools for surface modification. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Vienna were at last able to reconcile important issues concerning the effects of highly charged ions on surfaces.

Mysteries of Time: New Teaching Company Course | Cosmic Variance

Just in time for the holidays (Halloween totally counts as a holiday), the Teaching Company (a/k/a “The Great Courses) is releasing a new course I recorded — Mysteries of Modern Physics: Time.

Researchers say atomic clocks now good enough to measure Earth's geoid

(Phys.org)—Researchers from the University of Zurich say that atomic clock technology has sufficiently progressed to the point that it should now be feasible to use them to measure the Earth's geoid, thereby producing more accurate geophysical estimates of oil and mineral deposits, as well as water reservoirs.

Out There: Digging Up the Early Universe

Reconstructing ancient history is not easy to do. Just ask a paleontologist: No matter how many dinosaur skeletons or Neanderthal skulls scientists dig up, they still can tell only a small part of the story of what life on Earth was like millions, or even thousands, of years ago.
