In inner cities and poor rural areas across the country, public health advocates have been working hard to turn around food deserts — neighborhoods where fresh produce is scarce, and greasy fast food abounds. In many cases, they're converting dingy, cramped corner markets into lighter, brighter venues that offer fresh fruits and vegetables.
There's been a surge in earthquakes in the U.S. over the last few years. In Texas, there are 10 times the number of earthquakes now than just a few years ago.
Scientists say it's likely linked to the boom in oil and gas activity, meaning that people who never felt the ground shake are starting to.
Here's how Pat Jones of Snyder, Texas, describes the earthquake that struck her town in 2010: "It just sounded like some car hit the back of our house. We got up and checked around and we didn't see anything or hear anything else."

California, which has been experiencing its worst drought on record, is welcoming some heavy rainfall this weekend, but it's still too early to say if it signals a wholesale quenching of dried up streams and farm fields.
Coincidences confound us. Miracles amaze us. And the chance that the same person could be hit by lightning three different times, well, that just defies explanation. Or does it? David Hand is an emeritus professor of mathematics at Imperial College in London. And he has written a book called "The Improbability Principle: Why Coincidences, Miracles and Rare Events Happen Every Day." He joins us from the BBC studios in London. Thanks so much for being with us.
Wikipedia has become a go-to source for definitions, celebrity facts, and now, medical information. A study by the IMS Health Institute published in January names Wikipedia as the "single leading source" of health care information for both patients and health care professionals.

The oldest human ancestors to have walked on the British Isles left nothing except footprints. But they've made quite an impression on the world of science.
Researchers say 50 or so prints found on a beach near the village of Happisburg in Norfolk are the oldest known human footprints outside Africa. They were discovered last spring by a team of experts from the British Museum, the Natural History Museum and Queen Mary University of London.

There are different ways to think about animals. One way is to imagine them totally separate, not attaching to us, ever. "They are not brethren," wrote the great naturalist Henry Beston, "they are not underlings. They are other nations, caught with ourselves in the net of life and time." Animals and people, Beston thought, live in their own worlds while sharing the same streets, meadows, skies, homes. We mingle, but the gap between us is not crossable.

Days after a wide-ranging debate on creationism and evolution between Bill Nye and Ken Ham, the event is driving an online conversation. Themes of belief and literalism, logic and faith — and, for some, relevance — are being aired and disputed. And some wonder what the debate accomplished.
The video of the more than two-hour debate, in which Nye and Ham presented their views on how the Earth and its surroundings were created, has been viewed more than 830,000 times on YouTube. At one point, the live event drew more than 500,000 viewers.

Take a close look at the stunning image above showing a newly formed impact crater on Mars: The blue streaks of material, known as ejecta, radiate 9 miles from the 100-foot crater, according to NASA.
The picture was taken from orbit by the Mars Reconnaissance Orbiter on Nov. 19. The same area was imaged by the MRO's Context Camera in July 2010 and again in May 2012 — with no crater in the first and a telltale surface scar in the second.
They were some of the largest, hairiest animals ever to walk the Earth, but new research shows a big part of the woolly mammoth's diet was made up of tiny flowers.
The work is based on DNA analysis of frozen arctic soil and mammoth poop. It suggests that these early vegans depended on the flowers as a vital source of protein. And when the flowers disappeared after the last ice age, so too did the mammoths that ate them.
