For the first time, physicists have devised a way to make visible light travel in the opposite direction that it normally bends when passing from one material to another, like from air through water or glass. The phenomenon is known as negative refraction and could in principle be used to construct optical microscopes for imaging things as small as molecules, and even to create cloaking devices for rendering objects invisible.

Quick response! What's the best thing to do on a lifeboat with one too many people on board? Should one throw a mortally injured person overboard to ensure definite survival for everyone else, or refuse to act and ensure certain death for all individuals in the boat?

In the outer reaches of the solar system, there is an object known as 2003 EL61 that looks like and spins like a football being drop-kicked over the proverbial goalpost of life.

A team of astronomers led by Carl Grillmair of the California Institute of Technology has discovered some puzzling things about a Jupiter-sized planet that passes in front of a nearby star in the constellation Vulpecula.

The Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo interferometric gravitational-wave detector of the European Gravitational Observatory (EGO) near Pisa, Italy, have agreed to join in a collaborative search for gravitational waves from sources in and far beyond our galaxy. The collaboration will link the three LIGO detectors, which are in the United States, and LIGO's partner, GEO600 in Germany, with the Virgo detector to increase the likelihood of detecting the elusive phenomenon first predicted over 90 years ago by Albert Einstein in his general theory of relativity, and pinpointing the source of the signals.

Don't throw away your laptop yet, but there's a promising new high-tech invention being announced this week. Researchers have created a memory circuit the size of a white blood cell that has enough capacity to store the Declaration of Independence and have space left over. With 160 kilobits of capacity, it's the densest memory circuit ever fabricated.

An international team of astronomers has created a comprehensive three-dimensional map that offers a first look at the weblike large-scale distribution of dark matter in the universe. Dark matter is an invisible form of matter that accounts for most of the universe's mass, but that so far has eluded direct detection, or even a definitive explanation for its makeup.

Scientists are announcing this week their detection of a June 14 gamma-ray burst that probably signals a hitherto undetected type of cosmic explosion. The hybrid gamma-ray burst probably created a new black hole, but the details of how the explosion occurred are unclear.
