What Did I Do Last Summer? Oh, I Discovered How To Make Babies Without Sex. And You?

Robert Krulwich NPR

Ah, if only all summers could be like June, July and August 1740 — when three young guys (and a 6-year-old and a 3-year-old) did a science experiment that startled the world. In those days, you could do biology without a fancy diploma. More people could play.

How Can You Give A Community Better Health?

Ron Finley, renegade gardener, says food is both the problem and the solution.

Part 2 of the TED Radio Hour episode Giving It Away.

About Ron Finley's TEDTalk

Ron Finley plants vegetable gardens in South Central LA — in abandoned lots, traffic medians, along the curbs. Why? For fun, for defiance, for beauty and to offer some alternative to fast food in a community where "the drive-thrus are killing more people than the drive-bys."

A Small Shock To The System May Help Brain With Math

Ever get stuck on these?

Stimulating the brain with a very small electrical current through the forehead could boost a student's ability to learn and remember basic mathematics, a provocative experiment suggests.

The work, published online Thursday by the journal Current Biology, could help those who struggle with mental arithmetic. But the study was small and the long-term effect wasn't profound.

People smell yummy to mosquitoes.

So yummy, in fact, that our scent is a big way the pesky insects track us down.

But just how much mosquitoes like Eau de Human may not be entirely up to the bugs.

Mosquitoes are more attracted to human odors when they're infected with the malaria parasite, scientists reported Wednesday in the journal PLOS ONE.

Stem Cell Milestone Revives Intense Ethical Debate

Originally published on Thu May 16, 2013 4:56 am

Transcript

DAVID GREENE, HOST:

This is MORNING EDITION from NPR News. Good morning. I'm David Greene.

STEVE INSKEEP, HOST:

And I'm Steve Inskeep.

We're going to look closely this morning at a dramatic advance in science.

GREENE: And also its far-reaching implications. The advance involves embryonic stem cell research.

INSKEEP: Which scientists see as a route to dramatic advances in medical treatment. Researchers have now figured out how to make embryonic stem cells that carry a specific individual's DNA.

Cloning, Stem Cells Long Mired In Legislative Gridlock

After President Obama overturned Bush-era policy restricting federal funding of embryonic stem cell research in 2009, Nebraska Right to Life led a protest of the research outside the University of Nebraska regents' meeting.

The news that U.S. scientists have successfully cloned a human embryo seems almost certain to rekindle a political fight that has raged, on and off, since the announcement of the creation of Dolly the sheep in 1997.

Water Trapped For 1.5 Billion Years Could Hold Ancient Life

This map, from the United States Geological Survey, shows the age of bedrock in different regions of North America. Scientists found ancient water in bedrock north of Lake Superior. This region, colored red, was formed more than 2.5 billion years ago.

Scientists have discovered water that has been trapped in rock for more than a billion years. The water might contain microbes that evolved independently from the surface world, and it's a finding that gives new hope to the search for life on other planets.

The water samples came from holes drilled by gold miners near the small town of Timmins, Ontario, about 350 miles north of Toronto. Deep in the Canadian bedrock, miners drill holes and collect samples. Sometimes they hit pay dirt; sometimes they hit water, which seeps out from tiny crevices in the rock.

NASA Says Kepler's Planet-Searching Days May Be Numbered

Kepler-22b, the discovery of which was announced in December 2011, is one of many planets that bear the space telescope's name.

The planet-hunting career of NASA's Kepler spacecraft might be near its end.

Astronomers said Wednesday that a reaction wheel that keeps the orbiting telescope pointed at tiny, distant patches of sky to look for Earth-like planets has failed. If they can't fix it, Kepler will be relegated to a less prestigious mission, directing its gaze much closer to home in a search for so-called "near-Earth objects," i.e., meteors and asteroids.

Dam Removal Ushers In New Life In Washington State

Originally published on Thu May 16, 2013 5:59 am

Transcript

AUDIE CORNISH, HOST:

Two dams that block the migration of salmon are coming down in the largest dam removal in U.S. history. The dam sits on the Elwha River in the northwest corner of Washington state. They were built in the early 1900s to power nearby timber mills, but their power is no longer needed. From member station KUOW in Seattle, Ashley Ahearn reports that the removal is releasing a lot of debris but also creating new life.

How Researchers Cloned Human Embryos

Human embryos grow in a petri dish two days after scientists in Oregon cloned them from a donor's skin cell.

Scientists in Oregon have achieved something that many thought might be impossible.

They said Wednesday that they have cloned human embryos and then harvested the embryo's stem cells.

The discovery, if it holds up, means scientists would be able to make personalized stem cells, with their genetic code almost perfectly matched to that of a patient.

Analyzing The Language Of Suicide Notes To Help Save Lives

Originally published on Thu May 16, 2013 12:20 pm

Transcript

NEAL CONAN, HOST:

Every 14 minutes, someone in this country commits suicide, and research on ways to reduce that grim statistic appears to be on a plateau. In other words, psychologists don't have much in the way of new ideas - at least, right now - except maybe for what's described as groundbreaking work on the notes that those who kill themselves sometimes leave behind. A team of researchers at the Cincinnati Children's Hospital use computers to break down the language in these messages of despair, in the hope that they can better identify those at risk.

Go Fish (Somewhere Else): Warming Oceans Are Altering Catches

Crew members unload a catch of sockeye salmon at Craig, Alaska, in 2005. Researchers say fish are being found in new areas because of changing ocean temperatures.

Climate change is gradually altering the fish that end up on ice in seafood counters around the world, according to a new study.

"The composition of the [global] fish catch includes more and more fish from the warmer areas, and cold-water fish are getting more rare, because the temperatures are increasing," says Daniel Pauly at the University of British Columbia, a co-author of the study.
