The science of loneliness, making one of organic chemistry ’s oldest reactions safer, and a new book series
Researchers try to identify effective loneliness interventions, making the Sandmeyer safer, and books that look to the future and don’t see doom and gloom First up on the show, Deputy News Editor Kelly Servick explores the science of loneliness. Is loneliness on the rise or just our awareness of it? How do we deal with the stigma of being lonely? Also appearing in this segment:● Laura Coll-Planas● Julianne Holt-Lunstad● Samia Akhter-Khan Next, producer Ariana Remmel talks with Tim Schulte, a graduate student at the Max Planck Institute for Coal Research and RWTH Aachen University, abou...

Pregnancy's effect on 'biological' age, polite birds, and the carbon cost of home-grown veg
In this episode:00:35 Pregnancy advances your ‘biological’ age — but giving birth turns it backGrowing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA, but new research suggests that after giving birth, these changes can revert to an earlier state.Nature News: Pregnancy advances your ‘biological’ age — but giving birth turns it back08:07 Bird gestures to say 'after you'A Japanese tit (Parus minor) will flutter its wings to invite their mate to enter the nest first.

How to 3D print fully-formed robots
In this episode:00:46 Machine vision enables multi-material 3D printing3D printers are capable of producing complex shapes, but making functioning objects from multiple materials in a single print-run has proved challenging. To overcome this, a team has combined inkjet printing with an error-correction system guided by machine vision, to allow them to print sophisticated multi-material objects. They used this method to make a bio-inspired robotic hand that combines soft and rigid plastics to make mechanical bones, ligaments, and tendons, as well as a pump based on a mammalian heart.Research article: Buchner et al.News &...

Mysterious objects beyond Neptune, and how wildfire pollution behaves indoors
The Kuiper belt might be bigger than we thought, and managing the effects of wildfires on indoor pollution First up on this week’s show, the Kuiper belt—the circular field of icy bodies, including Pluto, that surrounds our Solar System—might be bigger than we thought. Staff Writer Paul Voosen joins host Sarah Crespi to discuss the distant Kuiper belt objects out past Neptune, and how they were identified by telescopes looking for new targets for a visit by the New Horizons spacecraft. Next up on the show, the impact of wildfire smoke indoors. Producer Kevin McLean talks with Delphine Farmer, a chemist at Colorado S...

Astronomers are worried by a satellite brighter than most stars
In this episode:00:45 A bright satellite is concerning researchersSatellites reflect sunlight down to Earth, and some do so with such intensity it risks obscuring astronomers' observations from ground-based telescopes. A paper in Nature suggests that the telecommunications satellite called BlueWalker 3 at times outshines most stars visible from Earth. Astronomers worry about the increasing number of such bright satellites making astronomy more difficult, and so the team suggest that future launches should undergo impact assessments.Research article: Nandakumar et al.Nature News: Huge new satellite outshines nearly every st...

Why does cancer spread to the spine? Newly discovered stem cells might be the key
In this episode:00:45 A new insight into cancers' selective spreadCancer cells can spread to bones in the late stages of disease and in many cancers, cells actually preferentially metastasise to the spine. The reason for this has been a puzzle to researchers for years, but now a team has found a new kind of stem cell that may be involved in this process. The stem cell is found in mice and humans and could represent a clinical target in the treatment of cancer.Research article: Sun et al.News and Views: Stem cells provide clues to why vertebrae attract tumour cells09:55 Research HighlightsA preference for certain percussion...

A mussel-inspired glue for more sustainable sticking
In this episode:00:46 A sustainably-sourced, super-strong adhesiveThe modern world is held together by adhesives, but these fossil-fuel derived materials come at an environmental cost. To overcome this, a team have developed a soya-oil based adhesive, which also takes inspiration from the proteins that marine animals like mussels use to stick firmly to rocks. The researchers say their glue is strong, reversible, and less carbon intensive to produce than existing adhesives.Research article: Westerman et al.07:43 Research HighlightsWhy chemicals derived from wood could be sustainable alternatives to a common plastic building...

Our ancestors lost nearly 99% of their population, 900,000 years ago
In this episode:00:30 Early humans pushed to brink of extinctionAround 900,000 years ago the ancestors of modern humans were pushed to the brink of extinction, according to new research. Genetic studies suggest that the breeding population of our ancestors in Africa dropped to just 1,280 and didn’t expand again for another 117,000 years. This population crash would likely have had an impact on human genetic diversity, and may have driven the evolution of important features of modern humans, such as brain size.Nature News: Human ancestors nearly went extinct 900,000 years ago3:49 The pollution legacy of Antarctica’s res...

Reducing calculus trauma, and teaching AI to smell
How active learning improves calculus teaching, and using machine learning to map odors in the smell space
First up on this week’s show, Laird Kramer, a professor of physics and faculty in the STEM Transformation Institute at Florida International University (FIU), talks with host Sarah Crespi about students leaving STEM fields because of calculus and his research into improving instruction.
We also hear from some Science staffers about their own calculus trauma, from fear of spinning shapes to thinking twice about majoring in physics (featuring Kevin McLean, Paul Voosen, Lizzie Wade, Meagan Cantwell, and FIU s...

This episode of Brain Science features the return of molecular biologist Seth Grant. We briefly review his decades of research into the complexity of the protein structure of the synapse and then we focus on his most recent paper, which describes how the life-span of synapse proteins appears to change as animals age. Grant reflects of the significance of this finding both for animal research and human medicine.This episode is appropriate for listeners of all backgrounds.Seth Grant has previously appeared on Brain Scien...

Basics of Neurotransmitters (BS 210)
click image to play episode, right click to download
This episode is our first review of neurotransmitters since episode 8 way back in 2007. We start with some basics of neuron function and brain anatomy, but the meat of the episode is a discussion of neurotransmitters and how they work. The key idea is that a simple molecule, such as dopamine, can have a wide variety of effects because of the existence of multiple receptors.This episode is appropriate for listeners of all backgrounds, but might be a little challenging for new listeners. It will be a review episode for longtime liste...
