Sinkholes can occur when porous limestone or other soluble bedrock dissolves in water, creating underground caverns that collapse.
Last Thursday evening, a man was in the bedroom of his home in Seffner, Florida.
These are typical narratives — one about scientific facts, the other about everyday life. We accept each narrative as neither shocking nor mysterious. Water and rock interact in particular ways. People go about their daily lives. This is familiar.
If they can block the Keystone XL pipeline, they can keep Canada from developing more of its dirty tar sands oil. It takes a lot of energy to get it out of the ground and turn it into gasoline, so it has a bigger greenhouse gas footprint than conventional oil.
Scientists believe a little girl born with HIV has been cured of the infection.
She's the first child and only the second person in the world known to have been cured since the virus touched off a global pandemic nearly 32 years ago.
Doctors aren't releasing the child's name, but we know she was born in Mississippi and is now 2 1/2 years old — and healthy. Scientists presented details of the case Sunday at a scientific conference in Atlanta.
So, last tuesday I explained why (in my humble opinion) the pop diva Beyoncé provided us with a nice example of overlap between Science and Art. In particular, I was thinking that, even though Beyoncé is not producing sonnets that will be read in 1000 years, she provides an example of a dedication to craft and excellence that is what scientists (at their best) also expect from themselves (minus the thumping beats — bummer).
Bright lights are part of a city's ecosystem. Think of Times Square or the Las Vegas Strip or right outside your bedroom window.
Electric lighting is ubiquitous in most urban and suburban neighborhoods. It's something most people take for granted, but appreciate, since it feels like well-lit streets keep us safer. But what if all this wattage is actually causing harm?
"We're getting brighter and brighter and brighter," warns Paul Bogard, author of the upcoming book, End of Night: Searching for Natural Darkness in an Age of Artificial Light.
The Dragon has been captured. The SpaceX unmanned craft connected with the International Space Station at 5:31 a.m. ET, NASA tweeted. The spacecraft arrived a day late due to mechanical problems after Friday's launch from Cape Canaveral, Fla.
The way Americans get their electricity is changing. Coal is in decline. Natural gas is bursting out of the ground in record amounts. And the use of wind and solar energy is growing fast. All this is happening as power companies are trying to choose which kind of energy to bet on for the next several decades.
Until recently, half of these plants burned coal to make electricity. Now, that's down to about one-third. Since 2010, about 150 coal plants either have been retired or it's been announced they will be retired soon.
Audie Cornish talks with AP correspondent Vanessa Gera about Polish inventor Wojciech Inglot, who died last weekend. Inglot invented a "breathable" nail polish, which became a surprise hit among Muslim women. The special polish allows them to fulfill the religious obligation of hand-washing before prayers, and still keep their manicures.
From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.
MELISSA BLOCK, HOST:
And I'm Melissa Block. We've reported a lot on the fight over the Keystone XL pipeline. It would carry oil from the tar sands of Canada all the way down to the Gulf of Mexico. And today, there's a development in this story. The State Department has released a new analysis of environmental impacts of the pipeline.
