Health Benefits Of Tea: Milking It Or Not

The idea that milk may diminish the potential heart-health benefits of tea has been a topic of some debate. Lots of us can't imagine black tea without a little dairy to cut the bitterness. But, according to this research going back to 2007, we might want to at least consider trying, say, a nice cup of green tea sans sugar or cream.

Streams Of Water Once Flowed On Mars; NASA Says Photos Prove It

Originally published on Fri March 21, 2014 4:20 pm

NASA says it has found proof that water shaped the rocks on the left, in a photograph taken by the Mars rover Curiosity (left). For comparison, the agency released an image of rocks from the Earth (right).

NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.

"You had water transporting these gravels to the downslope of the fan," NASA researchers say. The gravel then formed into a conglomerate rock, which was in turn likely covered before being exposed again.

Medical Electronics Built To Last Only A Little While

An electronic circuit in its first phases of dissolution.
Fiorenzo Omenetto

Most engineers build things to last.

But a group of mechanical and electrical engineers are working on electronics that will break down in as little as a couple of days. On purpose!

The electronic circuits they're developing don't crash. It's more dramatic than that. They dissolve in liquid.

Sounds a little bit crazy, but circuits that work for a while then disappear could be pretty useful in medical devices implanted in the human body.

Who Wants To Eat Jellyfish Omelettes? Dolphin Meatballs? Mouse-On-Toast? These Guys

Aaron Birk for NPR

Foodwise, we live in choosy times, mostly choosing "no thank you."

More and more of us choose not to eat meat or fish or eggs or fatty foods. We don't want anything too sugary, too fried, too raw, too strange. We tiptoe through the grocery as if it's a danger zone, hoping not to be tempted by a glazed doughnut.

On April 11 of this year, an extraordinary cluster of earthquakes struck off Sumatra. The largest shock, magnitude 8.7, produced stronger ground-shaking than any earthquake ever recorded. And it surprised seismologists by triggering more than a dozen moderate earthquakes around the world.

The quakes are also a sign of big changes to come in the Earth's crust.

New Groups Make A Conservative Argument On Climate Change

Former South Carolina Republican Rep. Bob Inglis now runs the Energy and Enterprise Initiative.

One topic you don't hear much about from Republican presidential nominee Mitt Romney is climate change. Like so much else, it's become politically divisive, with polls showing Republicans far less likely to believe in it or support policies to address it.

But two new groups aim to work from within, using conservative arguments to win over skeptics.

CEOs May Find It Lonely At The Top, But Not Stressful

MELISSA BLOCK, HOST:

This is ALL THINGS CONSIDERED from NPR News. I'm Melissa Block. It may indeed be lonely at the top, but apparently it's not as stressful as you might expect. New research finds that people in leadership positions show lower levels of stress and anxiety than workers further down the chain. Jennifer Lerner was on the research team at Harvard, which studied middle to high level officials from government, the military, business and nonprofits and she joins me to talk about what they found. Jennifer Lerner, welcome to the program.

Scientists Go Deep On Genes Of SARS-Like Virus

Originally published on Fri September 28, 2012 2:51 pm

Cheryl Gleasner, a research technologist at the Los Alamos National Laboratory, works with a genome sequencing machine designed for disease surveillance. Since the SARS epidemic in 2003, advances in sequencing technologies have greatly speed up the ability to detect and track a new virus.
Ross D. Franklin AP

When an unknown virus emerges, disease detectives turn to gene sequencers — not magnifying glasses — to identify the culprit.

So when a new type of coronavirus killed a man in Saudia Arabia and hospitalized another in the U.K., investigators got cracking.

Mammalian Surprise: African Mouse Can Regrow Skin

Originally published on Wed September 26, 2012 5:54 pm

The African spiny mouse has the ability to regrow large patches of skin and hair without scarring.
Ashley W. Seifert Nature

Scientists have discovered that a mouse found in Africa can lose large patches of skin and then grow it back without scarring, perhaps as a way of escaping the clutches of a predator.

The finding challenges the conventional view that mammals have an extremely limited ability to replace injured body parts. There are lizards that can regrow lost tails, salamanders that can replace amputated legs, and fish that can generate new fins, but humans and other mammals generally patch up wounds with scar tissue.
