Russians Drill Into Ancient Lake in Coldest Spot on Earth

Astronomers have discovered a trove of exoplanets--more than 700 worlds in orbit around distant stars, with leads on thousands of additional suspects.

The Newshour asked three experts to weigh in on the bird flu research debate.

Scientists are trying to develop tissue-like electronics that conform better to human organs. Elastic electronics, they call it.

Last week, a team of astronomers met in Arizona to discuss ambitious plans to see the unseeable. Using data pulled from a group of ground-based telescopes and assembled by a supercomputer, their plan is to capture, for the first time, an image of a black hole.

On Sunday, a gigantic solar flare erupted from out of the sun and began charging toward Earth at millions of miles an hour. But so far, no major damage reported.

The Supreme Court's decision Monday -- saying police must have a warrant before attaching a GPS tracker to vehicles -- shows the court "wants to move carefully" in weighing the privacy rights of individuals against law enforcement's need for information in criminal investigations, according to legal analyst Marcia Coyle.

Last year, questions were raised over how much research on the dangerous H5N1 virus -- or avian flu -- should be published in scientific journals. H5N1 is not yet transmissible among humans, though scientists have created a strain that can pass between ferrets.

House Democrats and Republicans picked up where they left off at the end of 2011, bickering about the creation of jobs or the lack thereof. President Obama rejected the construction of the Keystone XL pipeline that Republicans said would create more than 20,000 jobs.

In April 2011, Howard Falcon-Lang, a paleobotanist, was sifting through old collections in a poorly-lit storeroom at the British Geological Society, when he reached into a dark cabinet and pulled out a fossil with a signature that looked an awful lot like Charles Darwin's.

Last spring, a British scientist reached into the back of a cabinet and pulled out a fossil with a signature that looked an awful lot like Charles Darwin's. Turns out it was. Here is a sample of the fossils, which include seeds, extinct tree samples and fungus crushed into glass panels.
