NASA's Infrared Observatory Measures Expansion of Universe

Astronomers using NASA's Spitzer Space Telescope have announced the most precise measurement yet of the Hubble constant, or the rate at which our universe is stretching apart.

NASA'S Curiosity Rover Checks-In on Mars Using Foursquare

NASA's Curiosity Mars rover checked in on Mars Wednesday using the mobile application Foursquare. This marks the first check-in on another planet.

NASA Tournament Lab to Launch Big Data Challenge Series for U.S. Government Agencies

NASA, the National Science Foundation and the Department of Energy's Office of Science announced on Wednesday the launch of the Big Data Challenge, a series of competitions hosted through the NASA Tournament Lab (NTL).

Switching cause and effect in quantum world? A causes B causes A

A deeply rooted concept in everyday life is causality; the idea that events in the present are caused by events in the past and, in turn, act as causes for what happens in the future. Physicists have now shown that in quantum mechanics it is possible to conceive situations in which a single event can be both, a cause and an effect of another one.

Electromagnetic cloaking possible with ordinary plastic, study finds

A metal object can be made invisible with the help of ordinary plastic, Pekka Alitalo and Constantinos Valagiannopoulos, researchers from the School of Electrical Engineering, have shown in their study.

Swift progress on NSLS-II booster

The electrons that will generate intense, focused beams of x-rays at NSLS-II are accelerated to their target energy before they enter the large main ring. That crucial job falls on a complex of equipment known as the injector, consisting of a linear accelerator, booster ring, transport lines, and storage ring injection straight section.

Digging Up the Early Universe | Cosmic Variance

I wrote another column for Discover (the actual magazine), which is now available online. It’s about how far back in cosmological time we can push our knowledge on the basis of actual data, not mere theory.

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.
