Scientists Map Vast Reserves Of Freshwater Under The Seabed

Scientists published the first global survey of the known undersea freshwater reserves. Water is relatively cheap now, but the reserves could be valuable if it becomes scarcer in the future.

Not all the water in the sea is seawater.

Scientists think there are vast reserves of fresh groundwater buried under the oceans — a potentially valuable resource for coastal cities that need freshwater.

A recent report in Nature estimates the amount of fresh groundwater around the world at about 120,000 cubic miles — that's 100 times more than all the groundwater that has been pumped up from wells since the 1900s. The reserves are scattered across coastal regions around the world.

The Things We Did And Said In 2013, According To Facebook

What the world was talking about on Facebook in 2013. The social media site released a review of the most popular topics, events, and places Wednesday.

Did you travel in 2013? Perhaps you went to Disneyland. Or maybe you met someone special or watched the Super Bowl. Those moments of commonality are being highlighted by Facebook, which today released its list of the year's most popular topics, events and places.

After we spent a few moments reviewing the most common life events people reported in 2013, the list reads a bit like a 10-sentence short story — perhaps a fable or a coming-of-age tale.

See what you think: Here are the events Facebook says "people added to their Timeline most frequently in 2013."

Drug Companies Accept FDA Plan To Phase Out Some Animal Antibiotic Uses

If drug companies follow guidance issued Wednesday by the Food and Drug Administration, within three years it will be illegal to use medically important antibiotics to make farm animals grow faster or use feed more efficiently.

The FDA's announcement wasn't a big surprise; a draft version of the strategy was released more than a year ago.

Big Batteries Needed To Make Fickle Wind And Solar Power Work

PG&E, a Northern California utility company, is already experimenting with big batteries to store wind-generated electricity at its Vaca-Dixon Substation.

Giant batteries are coming to a power grid near you. In fact, they're already starting to appear on the grid in California.

That's because California is planning to rely increasingly on power supplies that aren't necessarily available every minute of every day. The state plans to get one-third of its electricity from wind and solar energy by 2020.

Utilities in the state are trying to figure out how they can cope with that uncertain power supply. Batteries aren't a panacea, but they could help.

Staph Germs Hide Out In The Hidden Recesses Of Your Nose

Otherwise innocuous bacteria can cause deadly infections when people have surgery or fall ill. To prevent trouble, patients sometimes have their bodies scrubbed clean of Staphylococcus aureus.

But it doesn't always work.

That may because the germs thrive in upper recesses of the nose, far from the spots typically tested for staph bacteria, or where antibiotics are applied.

Wake Up, Rosetta! Europeans Begin Checklist For Comet Landing

The European Space Agency's Rosetta probe, launched in March 2004, will be awakened from a deep sleep next month in preparation for a rendezvous with comet 67P/Churyumov-Gerasimenko, which will culminate late next year with the first-ever soft landing on such a body.

The 6,600-pound spacecraft, which has spent nearly a decade making repeated flybys of Earth and Mars to gain enough speed to catch the comet, was put in hibernation in July 2011, after its last major gravity-assist maneuver.

Rosetta's wake up call is set for Jan. 20, 2014 at precisely 1000 GMT (5 a.m. EST).

Looks like Harvard University scientists have given us another reason to walk past the cheese platter at holiday parties and reach for the carrot sticks instead: Your gut bacteria will thank you.

Switching to a diet packed with meat and cheese — and very few carbohydrates — alters the trillions of microbes living in the gut, scientists report Wednesday in the journal Nature.
