Genetic Engineering: Harvard Scientist George Church Seeks To “Reverse Aging” (60 Minutes Video)

Our lives have been transformed by the information age. But what’s coming next is likely to be more profound, call it the genetic information age. We have mapped the human genome and in just the last few years we have learned to read and write DNA like software. And you’re about to see a few breakthroughs-in-waiting that would transform human health. For a preview of this revolution in evolution we met George Church, a world leading geneticist, whose own DNA harbors many eccentricities and a few genes for genius.

Top New Sci-Fi Shows: “The Expanse – Season 4” Is “Real World Space Physics” (Science Magazine)

From a Science Magazine online article:

Science MagazineOn 13 December, Amazon Prime will air the fourth season of The Expanse, a hardboiled space drama renowned for its working-class characters and real-world space physics. Showrunner Naren Shankar is part of the reason the science checks out. The veteran writer and producer for programs such as Star Trek: The Next GenerationFarscape, and the police procedural CSI: Crime Scene Investigation, has a doctorate in applied physics and electrical engineering.

 When I got the script for the The Expanse, the pilot, I was, like, “Wow, this is a very different kind of a show.” Because they embraced all of the things that most science fiction shows run away from: the fact that you don’t have weight unless your ship is accelerating, the fact that communication in space is not instantaneous.

Shankar chatted with Science about why he feels it’s important to have a realistic sci-fi show, and how television work is like the scientific peer-review process.

New Research Videos: “Mining The Deep Sea” (MIT)

Mining minerals found 15,000 feet below sea level could help secure a low-carbon future, but at what cost? Researchers including Thomas Peacock, professor of mechanical engineering at MIT, are racing to understand the environmental impact of deep-sea mining.

Top Science Podcasts: Lab Monkey Retirement, Near-Earth Asteroids

scimag_pc_logo_120_120 (2)After their life as research subjects, what happens to lab monkeys? Some are euthanized to complete the research, others switch to new research projects, and some retire from lab life. Should they retire in place—in the same lab under the care of the same custodians—or should they be sent to retirement home–like sanctuaries? Online News Editor David Grimm joins host Sarah Crespi to discuss recently penned legislation that pushes for monkey retirements and a new collaboration between universities and sanctuaries to create a retirement pipeline for these primates.

Sarah also talks with Dante Lauretta, principal investigator for NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) and a professor at the University of Arizona in Tucson, about the latest news from the asteroid Bennu. Within 1 week of beginning its orbit of the asteroid, OSIRIS-REx was able to send back surprising images of the asteroid ejecting material. It’s extremely rocky surface also took researchers by surprise and forced a recalculation of the sample return portion of the craft’s mission.

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.
