Scientists have discovered a new, persistent structure in one of two radiation belts surrounding Earth. NASA's twin Van Allen Probes spacecraft have shown that high-energy electrons in the inner radiation belt display a persistent pattern that resembles slanted zebra stripes. Surprisingly, this structure is produced by the slow rotation of Earth, previously considered incapable of affecting the motion of radiation belt particles, which have velocities approaching the speed of light.
Sony is getting into the virtual reality business. The Japanese electronics and gaming giant unveiled a prototype virtual reality headset to be used in conjunction with its PlayStation 4 video game console during a Tuesday talk at the Game Developers Conference.
We now know what the famous announcement by the European Southern Observatory is. They found an asteroid with ring!

The find suggests that space-time really did expand at many times the speed of light in the first few tiny fractions of a second after the Big Bang, as predicted by the theory of cosmic inflation, researchers say.
Researchers in California have developed a new MRI technique which images wrist motion in real time. By capturing multiple scans per second, the team have been able to produce movies showing how one of the most complicated joints in the human body functions, a development that could lead to better surgical procedures and customized prosthetics in the future. Ben Gruber has more.
A new study of math anxiety shows how some people may be at greater risk to fear math not only because of negative experiences, but also because of genetic risks related to both general anxiety and math skills.
