Top New Science Podcasts: Quantum States In Space Lab, Barcode Bacteria

nature-podcastsThis week, the spaceborne lab that allows investigation of quantum states, and the debate surrounding how mountain height is maintained.

In this episode:

01:18 Space lab

10:48 Maintaining mountain height

For a long time many researchers have thought that mainly erosion controls the height of mountains, but new research suggests that tectonic forces play a bigger role. Research Article: Dielforder et al.News and Views: Mountain height might be controlled by tectonic force, rather than erosion

Technologies: New Plant-Based Plastics & Waste Plastic Into Hydrogen

Plastic has become a malevolent symbol of our wasteful society. It’s also one of the most successful materials ever invented: it’s cheap, durable, flexible, waterproof, versatile, lightweight, protective and hygienic.

During the coronavirus pandemic, plastic visors, goggles, gloves and aprons have been fundamental for protecting healthcare workers from the virus. But what about the effects on the environment of throwing away huge numbers of single-use medical protection equipment? How are we to balance our need for plastic with protecting the environment?

Delayed as a result of the pandemic, the film is being released now because it considers how society might ‘reset the clock’ when it comes to living better with a vital material.

We hear how Cambridge University’s Cambridge Creative Circular Plastics Centre (CirPlas) aims to eliminate plastic waste by combining blue-sky thinking with practical measures – from turning waste plastic into hydrogen fuel, to manufacturing more sustainable materials, to driving innovations in plastic recycling in a circular economy.

“As a chemist I look at plastic and I see an extremely useful material that is rich in chemicals and energy – a material that shouldn’t end up in landfills and pollute the environment,” says Professor Erwin Reisner, who leads CirPlas, funded by UK Research and Innovation.

“Plastic is an example of how we must find ways to use resources without irreversibly changing the planet for future generations.”

Top New Science Podcasts: Higher Covid-19 Severity In Men, Bacteria Tracking

science-magazine-podcastsFirst up this week, Staff Writer Meredith Wadman talks with host Sarah Crespi about how male sex hormones may play a role in higher levels of severe coronavirus infections in men. New support for this idea comes from a study showing high levels of male pattern baldness in hospitalized COVID-19 patients.

Next, Jason Qian, a Ph.D. student in the systems biology department at Harvard Medical School, joins Sarah to talk about an object-tracking system that uses bacterial spores engineered with unique DNA barcodes. The inactivated spores can be sprayed on anything from lettuce, to wood, to sand and later be scraped off and read out using a CRISPR-based detection system. Spraying these DNA-based identifiers on such things as vegetables could help trace foodborne illnesses back to their source. Read a related commentary piece.

Artificial Intelligence: “The Future From An Alternate Perspective”

The story follows our main character Luis as he tries to clearly explain the complexities and nuances of ‘language’, and the challenges of teaching AI to thoroughly understand it.

A massive project, an incredibly talented team, and a little bit of luck to get to the finish line. So thankful to my fellow artists and friends who helped pull this off.

New Research Podcasts: “Human Brains Are Wired To Enjoy Musical Pitch”

The Scientist PodcastsIn this month’s episode, we learn that human brains differentiate musical pitch a way that macaque monkeys do not. In fact, speech and music shaped the human brain’s hearing circuits. Researchers are studying these circuits with an eye on developing treatments for neurological disorders.

Top New Science Podcasts: New Skin That Grows Hair, Spontaneous RNA (Nature)

Nature PodcastThis week, Nature looks at a new method to grow hairy skin in a dish, and new research takes aim at the RNA world hypothesis.

In this episode:

00:45 Hairy Skin

Researchers may have developed a way to make skin that can grow hair in the lab, paving the way for treatment of a variety of skin disorders, and perhaps even baldness. Research Article: Lee et al.News and Views: Regenerative medicine could pave the way to treating baldness

08:56 Research Highlights

How mercury moved during the ‘Great Dying’, and the link between mobile phones and gender equality. Research Highlight: Giant eruptions belched toxic metal during the ‘Great Dying’Research Article: Rotondi et al.

11:21 Does DNA predate life?

The RNA world hypothesis posits that RNA formed spontaneously leading eventually to life. Now new research suggests that RNA and DNA formed together, before life. Research Article: Xu et al.News and Views: How DNA and RNA subunits might have formed to make the first genetic alphabet
