Big Picture Science for Aug 29, 2022 - Skeptic Check: Heal Thyself







Big Picture Science - Skeptic Check: Heal Thyself

(REPEAT) Do we still need doctors? There are umpteen alternative sources of medical advice, including endless and heartfelt health tips from people without medical degrees. Frankly, self-diagnosis with a health app is easier and cheaper than a trip to a clinic. Since we’re urged to be our own health advocate and seek second opinions, why not ask Alexa or consult with a celebrity about what ails us?

Find out if you can trust these alternative medical advice platforms. Plus, lessons from an AIDS fighter about ignoring the findings of medical science.

And, if AI can diagnose better than an MD, will we stop listening to doctors altogether?

It’s our monthly look at critical thinking … but don’t take our word for it!

Big Picture Science for Aug 22, 2022 - Platypus Crazy







Big Picture Science - Platypus Crazy

(REPEAT) They look like a cross between a beaver and a duck, and they all live Down Under. The platypus may lay eggs, but is actually a distant mammalian cousin, one that we last saw, in an evolutionary sense, about 166 million years ago.

Genetic sequencing is being used to trace that history, while scientists intensify their investigation of the habits and habitats of these appealing Frankencreatures; beginning by taking a census to see just how many are out there, and if their survival is under threat.

Guests:

  • Josh Griffiths – Senior Wildlife Ecologist at Cesaar Australia.
  • Jane Fenelon – Research fellow, University of Melbourne
  • Paula Anich – Professor of Natural Resources, Northland College
  • Wes Warren – Professor of Genomics, University of Missouri
  • Phoebe Meagher – Conservation Officer, Taronga Conservation Society, Australia

Big Picture Science for Aug 15, 2022 - Rip Van Winkle Worm







Big Picture Science - Rip Van Winkle Worm

(REPEAT) Your shower pipes are alive. So are your sinks, books, and floorboards. New studies of our homes are revealing just what species live there – in the thousands, from bacteria to flies to millipedes. Meanwhile, life keeps surprising us by popping up in other unexpected places: the deep biosphere houses the majority of the world’s bacteria and the Arctic tundra has kept worms frozen, but alive, for 40,000 years.

We embrace the multitude of life living on us, in us, and – as it turns out – in every possible ecological niche. Most of it is harmless, some is beneficial, and it’s all testament to the amazing diversity and adaptability of life. In addition, the hardiest organisms suggest where we might find life beyond Earth.

Big Picture Science for Aug 08, 2022 - Webb Feat









Big Picture Science - Webb Feat

The James Webb Space Telescope has turned its golden eye on the cosmos. The largest, most sensitive telescope put in space since the Hubble Space Telescope is already producing new photos of far-off galaxies and other cosmic phenomena.

In this episode: astronomers share their reactions to these stunning images, the project scientist on JWST describes how infrared cameras capture phenomena that are invisible to shorter wavelengths, and a plan to investigate the very stardust that created everything, including you and me.

Guests:

  • NĂ©stor Espinoza – Assistant astronomer, Space Telescope Science Institute, principal investigator for exoplanet atmospheric physics, James Webb Space Telescope
  • Alyssa Pagan – Science Visuals Developer at the Space Telescope Science Institute
  • John Mather – Nobel Prize-winning NASA astronomer and Senior Project Scientist for the James Webb Space Telescope
  • Alex Filippenko – Professor of Astronomy at the University of California, Berkeley

Big Picture Science for Aug 01, 2022 - Building a Space Colony









Big Picture Science - Building a Space Colony

Ready to become a space emigre? For half a century, visionaries have been talking about our future off-Earth – a speculative scenario in which many of us live in space colonies. So why haven’t we built them? Will the plans of billionaire space entrepreneurs to build settlements on Mars, or orbiting habitats that would be only minutes away from Earth, revive our long-held spacefaring dreams? And is having millions of people living off-Earth a solution to our problems… or an escape from them?
