Podcasts: “LabGenius” CEO James Field On AI/Machine Learning Discovering New Medicines (Babbage)

Babbage PodcastsResearchers are using artificial intelligence techniques to invent medicines and materials—but in the process are they upending the scientific method itself? The AI approach is a form of trial-and-error at scale, or “radical empiricism”. But does AI-driven science uncover new answers that humans cannot understand? Host Kenneth Cukier finds out with James Field of LabGenius…

Science Podcasts: NIH Scientist Loan Repayment Conflicts, Undersea Cables As Seismic Sensors

The National Instituscimag_pc_logo_120_120 (2)tes of Health’s largest loan repayment program was conceived to help scientists pay off school debts without relying on industry funding. But a close examination of the program by investigative correspondent Charles Piller has revealed that many participants are taking money from the government to repay their loans, while at the same time taking payments from pharmaceutical companies. Piller joins Host Sarah Crespi to talk about the steps he took to uncover this double dipping and why ethicists say this a conflict of interest.

Sarah also talks with Nate Lindsey, a Ph.D. candidate at the University of California, Berkeley, about turning a 50-meter undersea fiber optic cable designed to move data into a sensor for activity in the ocean and the land underneath. During a 4-day test in Monterey Bay, California, the cable detected earthquakes, faults, waves, and even ocean-going storms.

For this month’s books segment, Kiki Sandford talks with Dan Hooper about his book At the Edge of Time: Exploring the Mysteries of Our Universe’s First Seconds.

Brain Science Podcasts: MRI Scans Now Reveal “Thoughts And Feelings” (60 Minutes)

60 Minutes logoWho among us hasn’t wished we could read someone else’s mind, know exactly what they’re thinking? Well that’s impossible, of course, since our thoughts are, more than anything else, our own. Private, personal, unreachable. Or at least that’s what we’ve always, well, thought. 

Advances in neuroscience have shown that, on a physical level, our thoughts are actually a vast network of neurons firing all across our brains. So if that brain activity could be identified and analyzed, could our thoughts be decoded? Could our minds be read? Well, a team of scientists at Carnegie Mellon University in Pittsburgh has spent more than a decade trying to do just that. We started our reporting on their work 10 years ago, and what they’ve discovered since, has drawn us back.

Top Science Podcasts: Tracking Landslides In Taiwan, The Universality Of Music (ScienceMag)

scimag_pc_logo_120_120 (2)You may have seen the aftermath of a landslide, driving along a twisty mountain road—a scattering of rocks and scree impinging on the pavement. And up until now, that’s pretty much how scientists have tracked landslides—roadside observations and spotty satellite images. Now, researchers are hoping to track landslides systematically by instrumenting an entire national park in Taiwan. The park is riddled with landslides—so much so that visitors wear helmets. Host Sarah Crespi talks with one of those visitors—freelance science journalist Katherine Kornei—about what we can learn from landslides.

In a second rocking segment, Sarah also talks with Manvir Singh about the universality of music. His team asked the big questions in a Science paper out this week: Do all societies make music? What are the common elements that can be picked out from songs worldwide? Sarah and Manvir listen to songs and talk about what love ballads and lullabies have in common, regardless of their culture of origin.

Profiles: Stanford Physicist Robert Byer, 77, Helped Develop “Most Stable Laser In The World”

From a Stanford University News article:

Robert Byer uses an infrared viewing device to check the alignment of a near-IR laser through a linear crystal. Image credit Misha BrukByer also helped develop the quietest, most stable laser in the world, called the diode-pumped YAG laser. YAG lasers are today found in everything from communications satellites to green handheld laser pointers, which Byer co-developed with two of his graduate students and cites as one of his favorite inventions (he had joined Stanford in 1969). YAG lasers also form the main beams of the gravitational wave-detecting instrument, LIGO, which in 2015 achieved the most precise measurement ever made by humans when its antenna detected the tenuous spacetime fluctuations generated by two colliding black holes 1.3 billion light-years away.

Robert Byer was 22 years old when he first saw the light that changed his life.

Stanford NewsOne summer morning in 1964, Byer drove the hour from Berkeley down to Mountain View for a job interview at a California company called Spectra Physics. He walked in to find an empty lobby but could hear clapping and cheering in the back of the building. After politely waiting for several minutes, he followed the commotion to a darkened room filled with men whose jubilant faces were illuminated by a rod of red-orange light that seemed to float above an instrument-strewn table

Insites Into Neuroscience: “EEG – A Mental Map” Infographic (IMotions)

Knowing how someone thinks is crucial to understanding their behavior. With EEG (electroencephalography), you can get access to this hidden world, and reveal what’s really going on in someone’s mind. EEG offers many advantages, but it can be tricky to get your head around in the beginning. This infographic from iMotions is designed to give you a head start to this powerful technology.
