Solar Storm Goes Easy On Earth — But More Are Sure To Come, NASA Says

The huge solar storm that NASA detected hurtling toward Earth hit our planet at 5:42 a.m. ET Thursday. So far, there have been no reports of major power or communications disruptions. But it’s not the last you’ll hear about solar storms; the sun’s activity won’t peak until 2013.

Sun Sends Solar Flares Speeding Toward Earth; Will Hit Thursday [VIDEO]

The sun ejected two huge solar flares Tuesday, and NASA says that we here on Earth will likely be affected somewhat by the magnetic fields and ionized gas that are now shooting toward the planet. But the phenomena might also bring aurora light shows to residents of the northern United States

Antarctica Visitors Unwittingly Bring Invasive Species

The far reaches of Antarctica are no longer visited only by scientists and their support staff. Adventure tourists and curiosity seekers from Europe, North America and beyond now come by the boatful — and they’re bringing some souvenirs from home. Ecologist Steven Chown tells Robert Siegel that visitors unknowingly carry seeds on their clothes and bags. He says they’ve helped spread dozens of invasive plant species on the continent and risk permanently changing Antarctica’s ecology.

New Methods Could Speed Up Repair Of Injured Nerves

Scientists say they’ve developed a technique that reconnects the severed ends of a nerve, allowing it to begin carrying messages again very quickly — at least in rats. Usually, severed nerves must regrow from the point of injury — a process that can take months, if it ever happens.

Science Diction: The Origin Of ‘Tuberculosis’

When doctors autopsied tuberculosis patients, they described finding round, white swellings, especially in and around the lungs. Medical historian Howard Markel describes how those potato-like growths led to the disease being called tuberculosis, from the Latin tuber.

Weaving Around Web Privacy Controls

Web browser manufactures often market their products to consumers with an emphasis on privacy, assuring users that their products can better control how personal information is used online. Carnegie Mellon privacy researcher Lorrie Cranor explains that many companies have developed quiet ways to step around some of that privacy-protecting code.

Neutrinos May Not Travel Faster Than Light After All

Researchers in Italy say a bad connection between devices could explain a startling result they had last year, when they thought they’d witnessed particles traveling faster than the speed of light. Further tests await, but it appears there was a subtle problem with the equipment at the lab, as many physicists had expected. The laws of physics may not need to be rewritten after all.

Science Behind Avalanche ‘Air Bag’ Saves Skier

Three skiers died in an avalanche over the weekend in Washington state. A fourth skier was caught in the snow slide, but survived thanks to an airbag she deployed from her backpack. Audie Cornish speaks with Doug Abromeit, former director of and now consultant for the US Forest Service National Avalanche Center, about how the air bag works.

WHO Affirms Use Of Birth Control Injections After Weighing HIV Risks

The WHO upheld its guidelines on the safety of hormone injections for contraception yesterday, despite some data that users are at increased risk of HIV transmission. An expert panel says the evidence isn’t solid yet, and at-risk couples should use a second method, like condoms, for HIV prevention.

Many Jobs May Be Gone With The Wind Energy Credit

The wind power industry in this country has grown fast in recent years, but that could come to a screeching halt if Congress doesn’t renew a tax credit that wind farms get for the power they produce. Tens of thousands of jobs now depend on the tax credit, as more wind turbine manufacturers have taken root in the U.S.
