Saturn Shows Off A Massive Spinning Vortex: 'The Rose'

NASA is calling it "The Rose." By any other name, it's a mammoth storm on Saturn's north pole. Its eye spans an estimated 1,250 miles — 20 times the size of an average hurricane's eye on Earth. Winds in the Saturn storm's eye wall are believed to be four times as fast.

The stunning image of the spinning vortex was given "false colors" to emphasize low clouds (in red) versus high clouds (in green). NASA estimates that the clouds at the outer edge are moving at up to 330 miles per hour.

As the inventor of the telephone, Alexander Graham Bell is credited with bringing countless voices to our ears. And now, for the first time, here he is imploring us to hear his own voice:

The sound is scratchy. You have to strain to decipher it, but the words are clear. They're from Bell's lips, recorded in 1885 but unveiled just last week by the Smithsonian.

"It lets us know what the past was really like. It fills in a gap for people," says Shari Stout, collections manager at the Smithsonian's National Museum of American History.

For Corn, Fickle Weather Makes For Uncertain Yields

Originally published on Wed April 24, 2013 9:06 am

Last year's drought wreaked havoc on farmers' fields in much of the Midwest, cutting crop yields and forcing livestock producers to cull their herds. This spring, the rain that farmers needed so badly in 2012 has finally returned. But maybe too much, and at the wrong time.

It's almost the end of April, which is prime time to plant corn. But farmers need a break in the rain so they can get this year's crops in the ground and try to lock in good yields at harvest.

There's Trouble Brewing At The Birth Of The Universe

Originally published on Tue April 16, 2013 5:59 pm

Scientists can't just agree to disagree. It's not because we are stubborn or ornery (OK, maybe we are). It's because the whole point of science is to establish "public knowledge" — an understanding of the cosmos on which we can all agree. That is why there is trouble brewing at the beginning of the Universe.

There is a number, the Hubble Constant, that's fundamental to the study of the cosmos. The problem is, different folks are finding different values for that number and no one yet knows what that means.

Originally published on Tue April 16, 2013 8:45 am

Most research on memory loss in the elderly focuses on dementia, Alzheimer's disease or other brain diseases.

But neuroscientist Emily Rogalski from Northwestern University's Feinberg School of Medicine knew there is great variation in how good memory is in older people. Most have memory loss to varying degrees, but some have strong memories, even well into old age.

As Arctic Ice Melts, It's A Free-For-All For Oil ... And Tusks

Originally published on Tue April 23, 2013 11:47 am

It's widely known that the world's icecaps are melting. While most people are focused on what we're losing, some have considered what might be gained by the disappearance of all that ice.

In 2008, the U.S. Geological Survey released a report estimating that 13 percent of the world's remaining undiscovered oil and 30 percent of the remaining undiscovered natural gas could be in the Arctic.
