What's the matter with antimatter?

By Ben Brumfield, CNN

Nuclear scientists in Switzerland recently dropped some antimatter. The world didn't blow up, but there were some tiny explosions.

Scientists are hoping the experiment will teach them more about how the universe developed after the Big Bang.

Physicists with ALPHA Collaboration research group are trying to figure out how antimatter interacts with gravity, and if it produces "antigravity," says the group's founder, Jeffrey Hangst.

Their experiment mirrors the way Sir Isaac Newton came up with the law of gravity in the late 17th century.

Legend has it that an apple fell off a tree and hit the English nobleman on the head.

Newton got to thinking how gravity made the apple speed up as it fell.

Researchers: Jamestown settlers resorted to cannibalism

By Elizabeth Landau, CNN

The winter of 1609 to 1610 was treacherous for early American settlers. Some 240 of the 300 colonists at Jamestown, in Virginia, died during this period, called the "Starving Time," when they were under siege and had no way to get food.

Desperate times led to desperate measures. New evidence suggests that includes eating the flesh of fellow colonists who had already died.

Archaeologists revealed Wednesday their analysis of 17th century skeletal remains suggesting that settlers practiced cannibalism to survive.

Robot discovers secret chambers in Mexico

By CNN Mexico Staff

An advanced mini-robot named Tlaloc II-TC discovered three chambers built under the Temple of Quetzalcoatl, in the ancient city of Teotihuacan, built approximately 2,000 years ago in the northeast of what now is Mexico City.

Mexican archaeologists used the robot to access the last section of a very narrow tunnel under of the temple. The team, directed by Sergio Gómez Chávez, found multiple chambers instead of one, as it was expected, the National Institute of Anthropology and History (INAH) in Mexico said.

Tláloc II-TC is a system of three independent mechanisms. The main one is a transport vehicle that weights about 35 kilograms (77 pounds) and is approximately 45 cm tall. It features a scanner that can map its surroundings within a 5-meter radius.

Full moon involved in general's death?

By Ben Brumfield, CNN

A full moon hung just right in the night sky as the fierce Southern Army faced the encroaching Union troops in the spring of 1863.

Though they were outmanned and outgunned, the momentum of the war seemed to be on the side of Generals Robert E. Lee and "Stonewall" Jackson in Northern Virginia.

But the tide turned in the American Civil War not long after Jackson's own men inadvertently shot him that May night at the battle of Chancellorsville in Virginia.
