Science Podcast: Botox & Depression, Fruit Fly Sex Drive And New Books
First this week, Contributing Correspondent Cathleen O’Grady talks with host Sarah Crespi about controversy surrounding the use of Botox injections to alleviate depression by suppressing frowning.
Next, researcher Stephen Zhang, a postdoctoral fellow at the Beth Israel Deaconess Medical Center, discusses his Science Advances paper on what turns on the fruit fly sex drive. Finally, we are excited to kick off a six-part series of monthly interviews with authors of books that highlight the many intersections between race and science and scientists. This week, guest host and journalist Angela Saini talks with Keith Wailoo, professor of history and public affairs at Princeton University, who helped select the topics about the books we will be covering and how they were selected.
Science: How Humans Started Counting, Sea Anemones & ClownFish
The cross-discipline effort to work our how ancient humans learned to count.
In this episode:
00:45 Number origins
Around the world, archaeologists, linguists and a host of other researchers are trying to answer some big questions – when, and how, did humans learn to count? We speak to some of the scientists at the forefront of this effort.
News Feature: How did Neanderthals and other ancient humans learn to count?
07:47 Research Highlights
How sea anemones influence clownfish stripes, and how skin-to-skin contact can improve survival rates for high-risk newborns.
Research Highlight: How the clownfish gets its stripes

Science Podcast: Snow-Covered ‘Zombie Fires’, Flashy Plant Research
Smouldering fires lay dormant before bursting back into flame in spring.
In this episode:
00:56 The mysterious overwintering forest fires
Researchers have shown that fires can smoulder under snow in frozen northern forests before flaring up the following spring. Understanding how these so-called ‘zombie’ fires start and spread is vital in the fight against climate change.

10:04 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, Voyager 1 detects a faint interstellar ‘hum’, and a trove of Neanderthal bones found in an Italian cave.

Science: Stone Age Burial Site In Kenya, Metal-Free Rechargeable Batteries
The earliest evidence of deliberate human burial in Africa, and a metal-free rechargeable battery.
In this episode:
00:44 Human burial practices in Stone Age Africa
The discovery of the burial site of a young child in a Kenyan cave dated to around 78 thousand years ago sheds new light on how Stone Age populations treated their dead.
Research Article: Martinón-Torres et al.
News and Views: A child’s grave is the earliest known burial site in Africa
09:15 Research Highlights
How warming seas led to a record low in Northwestern Pacific typhoons, and the Arctic bird that maintains a circadian rhythm despite 24 hour sunlight.
Research Highlight: Warming seas brought an eerie calm to a stormy region
Research Highlight: The world’s northernmost bird is a clock-watcher
11:35 A metal-free rechargeable battery
Lithium-ion batteries have revolutionised portable electronics, but there are significant issues surrounding their recyclability and the mining of the metals within them. To address these problems, a team of researchers have developed a metal-free rechargeable battery that breaks down to its component parts on demand.
Research Article: Nguyen et al.
Science Podcast: Storing Wind As Gravity Batteries, Donkeys Digging Wells
Contributing Correspondent Cathleen O’Grady joins host Sarah Crespi to talk about a company that stores renewable energy by hoisting large objects in massive “gravity batteries.”
Also on this week’s show, Erick Lundgren, a postdoctoral researcher at Aarhus University, talks about how water from wells dug by wild horses and feral donkeys provides a buffer to all different kinds of animals and plants during the driest times in the Sonora and Mojave deserts.
Science: Inflatable Self-Supporting Structures, River Carbon Emissions
The self-supporting structures that snap into place, and how a ban on fossil-fuel funding could entrench poverty in sub-Saharan Africa.
In this episode:
00:45 Self-supporting, foldable structures
Drawing inspiration from the art of origami, a team of researchers have demonstrated a way to design self-supporting structures that lock into place after being inflated. The team hope that this technique could be used to create arches and emergency shelters that can be quickly unfolded from flat with minimal input.

07:32 Research Highlights
Nocturnal fluctuations cause scientists to underestimate rivers’ carbon emissions, and the ‘island rule’ of animal size-change is seen around the world.
Research Highlight: Rivers give off stealth carbon at night
Research Highlight: Animals around the world follow the ‘island rule’ to a curious fate
09:55 Banning fossil-fuel funding will not alleviate poverty
A ban by wealthy nations on the funding of overseas fossil-fuel projects would do little to reduce the world’s climate emissions and much to entrench poverty in sub-Saharan Africa, argues economist Vijaya Ramachandran.
World View: Blanket bans on fossil-fuel funds will entrench poverty
17:17 Briefing Chat
We discuss some highlights from the Nature Briefing. This time, the first powered flight on another world, and estimating how many Tyrannosaurus rex ever lived.
News: Lift off! First flight on Mars launches new way to explore worlds
Video: Flying a helicopter on Mars: NASA’s Ingenuity

Science Podcast: Muon Magnetism, The Counting Of All Tyranosaurus Rex
Host Sarah Crespi talks with Staff Writer Adrian Cho about a new measurement of the magnetism of the muon—an unstable cousin of the electron. This latest measurement and an earlier one both differ from predictions based on the standard model of particle physics. The increased certainty that there is a muon magnetism mismatch could be a field day for theoretical physicists looking to add new particles or forces to the standard model.
Also on this week’s show, Charles Marshall, director of the University of California Museum of Paleontology and professor of integrative biology, joins Sarah to talk about his team’s calculation for the total number of Tyrannosaurus rex that ever lived. In a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders interviews Imre Berger, professor of biochemistry at the University of Bristol, about his Science paper on finding a druggable pocket on the spike protein of SARS-CoV-2 and how the work was accelerated by intensive cloud computing. This segment is sponsored by Oracle for Research.
Science Podcast: Rural U.S. Sanitation Crisis, Manta Rays & Magnetic Muons
The lack of adequate sanitation in parts of the rural US, and physicists reassess muons’ magnetism.
In this episode:
00:45 How failing sanitation infrastructure is causing a US public health crisis
In the US, huge numbers of people live without access to adequate sanitation. Environmental-health advocate Catherine Coleman Flowers tells us about her new book looking at the roots and consequences of this crisis, focusing on Lowndes County, Alabama, an area inhabited largely by poor Black people, where an estimated 90% of households have failing or inadequate waste-water systems.
Book review: Toilets – what will it take to fix them?

Research Highlight: What manta rays remember: the best spots to get spruced up
10:13 Reassessing muons’ magnetic moment
A decade ago, physicists measured the ‘magnetic moment’ of the subatomic muon, and found their value did not match what theory suggested. This puzzled researchers, and hinted at the existence of new physics. Now, a team has used a different method to recalculate the theoretical result and see if this discrepancy remains.
