This month, NASA revealed new details of the plan to send humans to Mars by 2030. It's an elaborate and expensive mission, involving a giant deep-space rocket, and roping an asteroid into the moon's orbit to use as a stepping stone to Mars.

But there are still some serious questions about a manned expedition to Mars. Namely, is it safe? That's where astronauts Scott and Mark Kelly come in. The Kelly brothers are identical twins, and the only siblings ever to both fly in space.

This week in Seattle, Bill and Melinda Gates are attending a meeting of the minds.

Five hundred of the world's top innovators in global health have gathered for the Global Health Product Development Forum, an annual event in which scientists, engineers, policymakers and activists work to develop new tools for fighting diseases.

A little education goes a long way toward ensuring you'll recover from a serious traumatic brain injury. In fact, people with lots of education are seven times more likely than high school dropouts to have no measurable disability a year later.

How is biotechnology changing our pets, our livestock and other wild things? Ross Reynolds talks with Emily Anthes, the author of "Frankenstein’s Cat: Cuddling up to Biotech’s Brave New Beasts," about how biotech will change our pets and livestock.

This interview originally aired on March 14, 2013.

The Sichuan peppercorn is known to give some Chinese dishes a pleasant tingling feeling.

What's not so pleasant is that pins-and-needles feeling we get when our foot falls asleep — or when people who suffer from paresthesia experience constant tingling in their limbs.

Diana Bautista, a neuroscientist at the University of California, Berkeley, wondered: Could these sensations be connected?

It's looking like clouds will obscure Monday night's lunar eclipse for nearly all of the U.S. East Coast, but much of the West and Midwest should be able to see it.

A report that four young men who are paralyzed below the waist were able to move toes, ankles or knees when their lower spine was electrically stimulated was hailed as a breakthrough.

Ross Reynolds talks to Alan Boyle, science editor for NBCNews.com, about the recent discovery of water on Saturn's moon Enceladus. Boyle also talks about NASA's proposed mission to Europa and how the agency decides where to focus its space exploration dollars.

Think about how long you can hold your breath and then let this discovery blow your mind.

As search efforts intensify around the site of Washington state’s devastating mudslide, geologists are looking into causes of the rapid collapse of the 1,500-foot-wide segment of hillside in Snohomish County that suddenly cut away and crushed the homes and roads below.

The chief culprit appears to have been the glacial composition of the hillside, which is made of silt, clay and soil, and very little rock, which tends to be very loose.

Philip Mirowski's book, "Science Mart."

David Hyde talks with Philip Mirowski, author of "Science Mart: Privatizing American Science," about why he thinks the move to privately funded science is undermining the quality of the research.

"The types of science that are being done are changing, and the way in which science is being done is changing," Mirowski said. "In fact, the quality of some of the science is being affected by it too."

‘The Science Of Self’ With Jennifer Ouellette

Jennifer Ouellette's book, "Me, Myself, and Why."

What defines us? What determines our identity?

Jennifer Ouellette explores how eye color, likes and dislikes, and even hatred of cilantro construct our individual identities. She underwent personality tests and genome sequencing to determine the slight variations that set us all apart.

Ouellette is a blogger for "Scientific American" and the author of “Me, Myself, and Why: Searching for the Science of Self.” She spoke at Town Hall on February 25, 2014.

Ross Reynolds goes on a tour of the Intellectual Ventures Laboratory in Bellevue with inventor and futurist Pablos Holman.

Holman's team projects include a laser that can quickly detect if a person has malaria, a cooler that can keep vaccines from going bad and the high tech kitchen — more like a science lab actually — used to produce Nathan Myrhvold's 51 pound, multi-volume "Modernist Cuisine" books.

Cash prizes await "citizen scientists" who can improve algorithms that help NASA find and identify asteroids in our solar system, the agency says. A contest to find more asteroids begins next week, in what NASA calls an attempt to crowdsource innovation.
