NASA Scrambles for Better Asteroid Detection

NASA, universities and private groups in the U.S. are working on asteroid warning systems that can detect objects from space like the one that struck Russia last week with a blinding flash and mighty boom.

But the U.S. space agency reiterated that events like the one in the Urals, which shattered windows and injured nearly 1,000 people, are rare.

Climate Contradiction: Less Snow, More Blizzards

With scant snowfall and barren ski slopes in parts of the U.S. Midwest and Northeast the past couple of years, some scientists have pointed to global warming as the culprit.

Then, when a whopper of a blizzard smacked the Northeast with more than 2 feet (0.6 meters) of snow in some places earlier this month, some of the same people again blamed global warming.

Study: Hummingbirds Migrating Earlier in Spring

Ruby-throated hummingbirds are migrating to North America weeks earlier than in decades past, and research indicates that higher temperatures in their winter habitat may be the reason.

Researchers say the early arrival could mean less food at nesting time for the tiny birds that feed on insect pests, help pollinate flowers and are popular with birdwatchers.

Scientists Find Surgery, Cancer Use for Mussels

Mussels secrete a powerful adhesive to hold tight on rocks swept by violent waves -- and a synthetic version could prove critical for surgery and cancer treatment, researchers said Saturday.

Scientists have created materials that mimic the mussels' sticky proteins and could have medical applications such as sealants for fetal membrane repair, self-setting antibacterial hydrogels and polymers for to deliver cancer drugs and destroy cancer cells.

Scientists Claim Discovery of Russian Meteor Fragments

Scientists said Monday they had discovered fragments of the meteor that spectacularly plunged over Russia's Ural Mountains creating a shockwave that injured 1,200 people and damaged thousands of homes.

The giant piece of space rock streaked over the city of Chelyabinsk in central Russia on Friday with the force of 30 of the nuclear bombs dropped on the Japanese city of Hiroshima during World War II.

Biologists Create 'Zombie Cells' which Outperform Living Counterparts

Biological researchers have created dead 'zombie' cells in the lab which outperform living cells.

A team at Sandia National Laboratories and the University of New Mexico have innovated a technique whereby mammalian cells are coated with silica to form a near-perfect replicas.

Scientists Turn Eyes Toward Europa in Search for Life

U.S. astronomers looking for life in the solar system believe that Europa, one of the moons of Jupiter, which has an ocean, is much more promising than desert-covered Mars, which is currently the focus of the U.S. government's attention.

"Europa is the most likely place in our solar system beyond Earth to possess .... life," said Robert Pappalardo, a planetary scientist at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California.

Russian Region Begins Recovery from Meteor Fall

A small army of workers is laboring to replace the estimated 200,000 square meters (50 acres) of windows shattered by the shock wave from a meteor that exploded over Russia's Chelyabinsk region.

The astonishing Friday morning event blew out windows in more than 4,000 buildings in the region, mostly in the capital city of the same name and injured some 1,200 people, largely with cuts from the flying glass.
