Big Picture Science for Mar 13, 2023 - Flower Power









Big Picture Science - Flower Power

Before everything could come up roses, there had to be a primordial flower – the mother, and father, of all flowers. Now scientists are on the hunt for it. The eFlower project aims to explain the sudden appearance of flowering plants in the fossil record, what Darwin called an “abominable mystery.”

Meanwhile, ancient flowers encased in amber or preserved in tar are providing clues about how ecosystems might respond to changing climates. And, although it was honed by evolution for billions of years, can we make photosynthesis more efficient and help forestall a global food crisis?

Guests:

  • Eva-Maria Sadowski - Post doctoral paleobotanist at the Museum für Naturkunde, Berlin
  • Regan Dunn - Paleobotanist and assistant Curator at the La Brea Tar Pits and Museum
  • Royal Krieger - Rosarian and volunteer at the Morcom Rose Garden, Oakland, California
  • Ruby Stephens - Plant ecology PhD candidate at Macquarie University in Australia, and member of the eFlower Project
  • Stephen Long - Professor of Plant Science, University of Illinois

Big Picture Science for Mar 06, 2023 - Lady Parts









Big Picture Science - Lady Parts

REPEAT
The Supreme Court’s ruling on Roe has ignited fierce debate about bodily autonomy. But it’s remarkable how little we know about female physiology. Find out what studies have been overlooked by science, and what has been recently learned. Plus, why studying women’s bodies means being able to say words like “vagina” without shame ... a researcher who is recreating a uterus in her lab to study endometriosis …  and an overdue recognition of medical pioneer Dr. Rebecca Lee Crumpler.

Big Picture Science for Feb 27, 2023 - Waste Not







Big Picture Science - Waste Not

REPEAT
Why create more landfill? Perhaps you should resist the urge to toss those old sneakers, the broken ceiling fan, or last year’s smart phone. Instead, repurpose them! Global junk entrepreneurs are leading the way in turning trash to treasure, while right-to-repair advocates fight for legislation that would give
you a decent shot at fixing your own electronic devices.

And, if you toss food scraps down the drain as you cook, are you contributing to a “fatberg” horror in the sewer?

Big Picture Science for Feb 20, 2023 - Post Social Media









Big Picture Science - Post Social Media

Before you check your social media feeds today. And post. And post again. And get into an argument on Twitter, lose track of time and wonder where the morning went, consider that social media was never a natural way to socialize.

A cultural anthropologist weighs in on the evolutionary reasons humans can’t thrive on social media. And we hear about the signs that social media is on its way out. If that’s the case, what’s next?

Big Picture Science for Feb 13, 2023 - Fungi Fear









Big Picture Science - Fungi Fear

The zombie eco-thriller “The Last of Us” has alerted us to the threats posed by fungi. But the show is not entirely science fiction.  Our vulnerability to pathogenic fungi is more real than many people imagine.

Find out what human activity drives global fungal threats, including their menace to food crops and many other species. Our high body temperature has long kept lethal fungi in check; but will climate change cause fungi to adapt to warmer temperatures and threaten our health?

Plus, a radically new way to think about these organisms, how they make all life possible, and how we might find balance again.

Big Picture Science for Feb 06, 2023 - Math's Paths







Big Picture Science - Math's Paths

REPEAT
If you bake, you can appreciate math’s transformative properties. Admiring the stackable potato chip is to admire a hyperbolic sheet. Find out why there’s no need to fear math - you just need to think outside the cuboid.  Also, how nature’s geometric shapes inspire the next generation of squishy robots and an argument for radically overhauling math class. The end point of these common factors is acute show that’s as fun as eating Pi

Big Picture Science for Jan. 30, 2023 - Skeptic Check: Understanding UAPs









Big Picture Science - Skeptic Check: Understanding UAPs

The newest Pentagon report on UAPs – or Unidentified Aerial Phenomenon – reflects long standing public interest about what’s in our skies. Now, NASA is investigating for themselves.

Should we assume that what we can’t identify is alien visitation? In our regular look at critical thinking, we look at the history of UFO sightings, visit Roswell on the 75th anniversary of the crash, and ask how our desire to believe influences our interpretation of evidence.

Guests:

  • Paul Hynek - Teacher at Pepperdine University and son of the late astronomer J. Allen Hynek
  • Roger Launius - Former chief historian for NASA and former Chair of the Division of Space History at the Smithsonian National Air and Space Museum

Big Picture Science for Jan. 23, 2023 - Vaccine Inequity









Big Picture Science - Vaccine Inequity

(REPEAT)
A radical plan could solve a historic global health inequity. Countries in the global south who waited for more than a year for ample supplies of Covid vaccines have banded together to make mRNA vaccines locally. If successful, they could end a dangerous dependency on wealthy nations and help stop pandemics before they start.

In a special episode, supported by the Pulitzer Center, journalist Amy Maxmen shares her reporting from southern Africa about the inspiring project led by the WHO that’s made fast progress. But it could fail, and a global imbalance will remain, if Big Pharma has its way. Find out what’s at stake.

Guests:

  • Amy Maxmen - Award-winning science journalist, Edward R. Murrow press fellow at the Council on Foreign Relations and author of the Nature article, "The Radical Plan for Vaccine Equity"
  • Petro Terblanche - Managing Director, Afrigen Biologics and Vaccines in Cape Town, South Africa
  • Kondwani Charles Jambo - Senior Lecturer and immunologist at the Malawi-Liverpool-Wellcome Clinical Research Programme in Blantyre, Malawi
  • Barney Graham - Former deputy director at the Vaccine Research Center at NIH and professor of medicine and microbiology immunology biochemistry at Morehouse School of Medicine
  • Emile Hendricks - Research technologist at Afrigen Biologics and Vaccines in Cape Town, South Africa
  • Achal Prabhala - Fellow at the Shuttleworth Foundation, Coordinator at AccessIBSA, a medicines-access initiative in Bengaluru, India
  • Patrick Tippoo - Head of Science and Innovation at Biovac in Cape Town, South Africa, founding member of the African Vaccine Manufacturing Initiative (AVMI)

Big Picture Science for Jan. 16, 2023 - Testing Your Metal









Big Picture Science - Testing Your Metal

(REPEAT)
Catalytic converters are disappearing. If you’ve had yours stolen, you know that rare earth metals are valuable. But these metals are in great demand for things other than converters, such as batteries for electric cars, wind farms and solar panels.

We need rare earth metals to combat climate change, but where to get them? Could we find substitutes?

One activity that could be in our future: Deep sea mining. But it’s controversial. Can one company’s plan to mitigate environmental harm help?

Guests:

  • Paul Dauenhauer - Professor of chemical engineering and material science at the University of Minnesota and a 2020 MacArthur Fellow
  • Chris Leighton - Distinguished University Teaching Professor, Editor, Physical Review Materials, Dept. of Chemical Engineering and Materials Science, University of Minnesota

Big Picture Science for Jan. 09, 2023 - Melting Down








 

Big Picture Science - Melting Down

(REPEAT)
Climate change isn’t waiting for us to act. We’ve missed several deadlines to mitigate the dangers of this existential threat, which suggests we prefer to avert our gaze rather than deal with the problem. It’s similar to the way society reacts to an incoming comet in the movie “Don’t Look Up!”

As a major Antarctic ice sheet shows signs of collapse, it’s no wonder we feel some “climate anxiety.” Can we leverage this emotion to spur action?  That, and where hope lies, in this episode.

Big Picture Science for Jan. 02, 2023 - Coming to Our Animal Senses








 

Big Picture Science - Coming to Our Animal Senses

(REPEAT)
Animals experience the world differently. There are insects that can see ultraviolet light, while some snakes can hunt in the dark thanks to their ability to sense infrared. Such differences are not restricted to vision: Elephants can hear subsonic sounds, birds navigate by magnetism, and your dog lives in a world marked by odors. In this episode, we speak to science journalist Ed Yong about how other creatures sense the world. Could we ever understand what it’s like to have the hearing of a bat or the sight of a hawk?

Big Picture Science for Dec. 19, 2022 - Skeptic Check: 5G









Big Picture Science - Skeptic Check: 5G

(REPEAT) 5G, the latest mobile network standard, is coming. As new cell towers sprout around the world, do we know enough to confidently claim that this new technology is safe? After all, older networking standards relied on microwaves, radiation which has wavelengths of inches to a foot or so. 5G operates at much higher frequencies, with millimeter wavelengths.

Some are worried that being subjected to millimeter radiation could cause cancers. But what does science say? 5G: the promise and the perils.

Big Picture Science for Dec. 12, 2022 - Tomb with a View









Big Picture Science - Tomb with a View

A century ago, British archaeologist Howard Carter opened the only surviving intact tomb from ancient Egypt. Inside was the mummy of the boy king Tutankhamun, together with “wonderful things” including a solid gold mask.

Treasure from King Tut’s crypt has been viewed both in person and virtually by many people since. We ask what about Egyptian civilization so captivates us, thousands of years later. Also, how new technology from modern physics allows researchers to “X-Ray” the pyramids to find hidden chambers

Big Picture Science for Dec. 05, 2022 - Keeping Humans in the Loop







Big Picture Science - Keeping Humans in the Loop

(REPEAT) Modern technology is great, but could we be losing control? As our world becomes more crowded and demands for resources are greater, some people worry about humanity’s uncertain prospects. An eminent cosmologist considers globe-altering developments such as climate change and artificial intelligence. Will we be able to stave off serious threats to our future?

There’s also another possible source of danger: our trendy digital aids. We seem all-too-willing to let algorithms classify and define our wants, our needs, and our behavior. Instead of using technology, are we being used by it – to inadvertently become social media’s product?

And while we may be skittish about the increased data our technology collects, one sci-fi writer imagines a future in which information is a pervasive and freely available commodity.
