Scientists based their technique on the one used to create the sheep Dolly years ago. These cells might one day be useful in treating all sorts of diseases.

There's no treatment yet for the deadly viral disease, but several approaches are in the works. At least one experimental drug seems effective in monkeys. Next step: safety tests in people.

New drugs are usually tested in animals before they're tested in humans. But many of those studies aren't done carefully enough, analysts say. So time and money is wasted, and treatments are delayed.

Several scientific teams are developing sensitive tests for tumor DNA that, when perfected, could be used to diagnose cancer earlier, and more closely monitor the response to treatment.

It's not about making designer beer. Johns Hopkins scientists and undergrads stitched together strands of yeast DNA as a step in exploring the essential genetics of various species: What makes us us?

More than 70,000 deaths a year are caused by hospital-acquired infections, a CDC survey of U.S. hospitals finds. The numbers are improving, doctors say, but not fast enough.

The human nose may be able to distinguish more than a trillion different odors and fragrances, research hints. If true, our noses are much more discerning with smells than our eyes are with color.

A look back confirms that adults treated with Tamiflu, Relenza or a related drug were half as likely to die in the hospital as those who caught the pandemic flu strain and weren't treated.

It sounds like a good idea: anticipating flu's spread by monitoring a region's online searches. But sometimes a sneeze is just a cold.

To forecast sudden global catastrophe — and, perhaps, head it off — we should be spying on the climate at least as closely as we spy on each other, an expert panel warns. Yet the primary global monitoring network has been cut by 30 percent.

Renewable energy has become a $220 billion a year industry. But to significantly slow climate change, the power of wind, solar and other renewable sources must vastly expand. Some say the tech breakthroughs needed are on the horizon, though a top economist sees a tougher road ahead.

Scientists say Typhoon Haiyan is one of the strongest ever recorded, though limited measurements may prevent them from declaring it as the record holder. Still, the storm was devastating: "We had a triple whammy of surge, very high winds and strong rainfall," says one climate scientist.

If you commute to work, chances are you travel on roads or rails. A designer in Austin, Texas, wonders, "Why not up in the air?" In a nod to orangutans at the National Zoo who get around on wires 50 feet above the ground, designers see the potential for aerial mass transit.

Diplomats are again meeting to consider setting aside a protected zone in the pristine waters around Antarctica, though their previous negotiations ended in failure. A scaled-back plan on the table this week would still create the largest marine preserve in the world.

This is the 40th anniversary of the Arab Oil Embargo, which triggered a seven-year energy crisis. The results of the energy crisis are still with us — both in the political fault-lines in Washington and in the cars that are on our roads.

"This is the real deal. Voyager 1 has finally reached interstellar space; the first time a spacecraft has been in the space between the stars," says one project scientist. Launched in 1977, the probe has been surveying the solar system.

About 160 years ago, Europe's glaciers began melting, centuries before the temperatures started rising. Now NASA scientists offer a possible explanation for this apparent paradox: Soot from the Industrial Revolution could have heated up the ice. (This piece initially aired Sept. 3 on Morning Edition.)

Scientists looking back on last year's extreme weather events conclude that human-induced climate change didn't cause any of the events, but appears to have made some of them worse. The results are published in the Bulletin of the American Meteorological Society.

About 160 years ago, before Europe began warming up, glaciers in the Alps started rapidly retreating. Now NASA scientists offer a possible explanation for this apparent paradox: Soot from the Industrial Revolution could have heated up the ice.

Greenland is covered in an ice layer that's up to 2 miles thick. But below the ice, there's a vast terrain of bedrock. Now scientists have found a mega-canyon there, twice the size of the one in Arizona. The hidden canyon is drawing oohs and aahs from scientists around the world.
