What time is it on Mars? | Nagin Cox

Nagin Cox is a first-generation Martian. As a spacecraft engineer at NASA's Jet Propulsion Laboratory, Cox works on the team that manages the United States' rovers on Mars. But working a 9-to-5 on another planet -- whose day is 40 minutes longer than Earth's -- has particular, often comical challenges.![image] (http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/Dbk7n-dE6O8) ...

A robot that eats pollution | Jonathan Rossiter

Meet the "Row-bot," a robot that cleans up pollution and generates the electricity needed to power itself by swallowing dirty water. Roboticist Jonathan Rossiter explains how this special swimming machine, which uses a microbial fuel cell to neutralize algal blooms and oil slicks, could be a precursor to biodegradable, autonomous pollution-fighting robots.![image] (http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/w3eDGu1XoWc) ...

Lifelike simulations that make real-life surgery safer | Peter Weinstock

Critical care doctor Peter Weinstock shows how surgical teams are using a blend of Hollywood special effects and 3D printing to create amazingly lifelike reproductions of real patients -- so they can practice risky surgeries ahead of time. Think: "Operate twice, cut once." Glimpse the future of surgery in this forward-thinking talk.![image] (http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/xp4MM5AcFSU) ... Read more

3 ways to spot a bad statistic | Mona Chalabi

Sometimes it's hard to know what statistics are worthy of trust. But we shouldn't count out stats altogether ... instead, we should learn to look behind them.

How early life experience is written into DNA | Moshe Szyf

Moshe Szyf is a pioneer in the field of epigenetics, the study of how living things reprogram their genome in response to social factors like stress and lack of food. His research suggests that biochemical signals passed from mothers to offspring tell the child what kind of world they're going to live in, changing the expression of genes. "DNA isn't just a sequence of letters; it's not just a script." Szyf says. "DNA is a dynamic movie in which our experiences are being written."![image] (http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/3ze-khf7TR4) ... Read more

How to take a picture of a black hole | Katie Bouman

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth -- until Katie Bouman and a team of astronomers came up with a clever alternative. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope.![image] (http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/zfSuJgo9Rb0) ... Read more

How radio telescopes show us unseen galaxies | Natasha Hurley-Walker

Our universe is strange, wonderful and vast, says astronomer Natasha Hurley-Walker. A spaceship can't carry you into its depths (yet) -- but a radio telescope can. In this mesmerizing talk, Hurley-Walker shows how she probes the mysteries of the universe using special technology that reveals light spectrums we can't see.![image] (http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/1evUnLZL6wQ) ...

How human noise affects ocean habitats | Kate Stafford

Oceanographer Kate Stafford lowers us into the sonically rich depths of the Arctic Ocean, where ice groans, whales sing to communicate over vast distances -- and climate change and human noise threaten to alter the environment in ways we don't understand. Learn more about why this underwater soundscape matters and what we might do to protect it.![image] (http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/a0sL2h7R6mM) ... Read more
