Robert Sapolsky bio

Posted by in categories: biological, education, genetics, health, neuroscience

Robert Sapolsky is one of the world’s leading neuroscientists, with a focus on the physiological effects of stress. (For years, he spent his summers in Kenya, alone except for the baboons he was observing.) Steve asks Robert why we value human life over animals, why he’s lost faith in the criminal justice system, and how to look casual when you’re about to blow-dart a very large and potentially unhappy primate.\

ABOUT FREAKONOMICS RADIO NETWORK:\
Freakonomics began as a book, which led to a blog, a documentary film, more books, a pair of pants, and in 2010, a podcast called Freakonomics Radio. Hosted by Stephen J. Dubner, it’s one of the most popular podcasts in the world, with a reputation for storytelling that is both rigorous and entertaining. Its archive of more than 500 episodes is available, for free, on any podcast app, and the show airs weekly on NPR stations. Freakonomics Radio is now the flagship show of the Freakonomics Radio Network, which includes the podcasts No Stupid Questions (est. 2020), People I (Mostly) Admire (2020), and Freakonomics, M.D. (2021). \

Dark stars may be waiting in a mirror universe for us to discover them

Posted by in categories: cosmology, physics

Physicists have proposed that a mirror universe alongside our own might explain dark matter – and we might be able to see traces of its stars.

Quantum Batteries Could Provide a New Kind of Energy Storage by Messing With Time

Posted by in categories: particle physics, quantum physics

In a typical battery, charged ions zip one way through a sea of other particles as the battery recharges, before racing back in the other direction to release the stored energy on cue.

Back and forth the ions go, some getting diverted along the way, until the capacity of the battery is drained, and it loses energy too quickly to be of any use.

But physicists, good on them, are imagining new ways of storing energy in handy portable devices by drawing on a strange quantum phenomenon that twists time, amongst other unusual happenings.

Defying Genetics: How One Patient’s Unique Mutation Offers New Hopes in Alzheimer’s Prevention

Posted by in categories: biotech/medical, genetics, neuroscience

Breaking link between early, late stages of disease may prevent dementia.

Alzheimer’s disease has plagued one large Colombian family for generations, striking down half of its members in the prime of life. But one member of that family evaded what had seemed would be fate: Despite inheriting the genetic defect that caused her relatives to develop dementia in their 40s, she stayed cognitively healthy into her 70s.
