Up until now, the invisibility cloaks have been bulky contraptions–not easy to slip on and off for people who want to role play Harry Potter. However, researchers have now developed a cloak that is just micrometers thick.

Objects are detected when waves–whether they are sound, light, x-rays or microwaves– rebound off its surface. The reason we see objects is because light rays bounce off their surface towards our eyes and our eyes are able to process the information.

While previous cloaking studies have used metamaterials to bend the incoming waves around an object, this new method uses an ultrathin metallic screen to cancel out the waves as they are scattered off the cloaked object.

NASA plans to robotically capture a small near-Earth asteroid and redirect it safely to a stable orbit in the Earth-moon system where astronauts can visit and explore it. Is this part of NASA’s search for potential "killer" asteroids?

At a recent Congressional hearing, NASA told lawmakers that it’s time for the private sector to aid in the search for potentially city-destroying asteroids and meteors.

Increased exposure to traffic-related air pollution during pregnancy is associated with a higher incidence of leukemia in children. This means that China–the most polluted country in the world–is headed for a cancer epidemic caused by bad air–among other things.

Researcher Julia Heck says, "We studied pregnancy exposures because the fetus is likely to be more vulnerable to environmental factors during that time, and we also know that certain childhood cancers originate in utero."

A computer can predict what you’re dreaming about (NOTE: Subscribers can still listen to this fascinating show) based on your brain wave activity with an fMRI machine.

On Fox News, Tia Ghose quotes neuroscientist Masako Tamaki as saying, "Using this method, we might be able to know more about the function of dreaming."

WHY we dream is still a mystery. Sigmund Freud thought dreams were about secret desires and wish fulfillment, but modern researchers think that they are irrelevant "trash" that the brain throws out. Another theory is that dreams allow our minds to keep working on problems while we’re asleep. read more
