How whales sing without drowning, an anatomical mystery solved
The deep haunting tones of the world's largest animals, baleen whales, are iconic - but how the songs are produced has long been a mystery. Whales evolved from land dwelling mammals which vocalize by passing air through a structure called the larynx - a structure which also helps keep food from entering the respiratory system. However toothed whales like dolphins do not use their larynx to make sound, instead they have evolved a specialized organ in their nose. Now a team of researchers have discovered the structure used by baleen whales - a modified version of the larynx. Whales like Humpbacks and Blue whales are abl...

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...

The Nature Podcast ’s highlights of 2022
In this episode:00:53 How virtual meetings can limit creative ideasIn April, we heard how a team investigated whether switching from face-to-face to virtual meetings came at a cost to creativity. They showed that people meeting virtually produced fewer creative ideas than those working face-to-face, and suggest that when it comes to idea generation maybe it’s time to turn the camera off.Nature Podcast: 27 April 2022Research article: Brucks & LevavVideo: Why video calls are bad for brainstorming08:29 How the Black Death got its startThe Black Death is estimated to have caused the deaths of up to 60% of the population ...

Missing foot reveals world ’s oldest amputation
00:46 Evidence of ancient surgeryA skeleton with an amputated foot discovered in Borneo has been dated to 31,000 years ago, suggesting that complex surgery might be much older than previously thought. The person whose foot was removed survived the procedure, which the researchers behind the find say shows the ‘surgeon’ must have had detailed knowledge of anatomy, and likely had access to antiseptic compounds.Research article: Maloney et al.News and Views: A surgical dawn 31,000 years ago in Borneo10:12 Research HighlightsMummified reptiles hint at severe drought 250 million years ago, and mapping avalanche risk in remo...

X-ray analysis hints at answers to fossil mystery
00:45 The puzzle of PalaeospondylusOver a hundred years ago, archaeologists discovered fossils of the aquatic animal Palaeospondylus. But since then researchers have been unable to place where this animal sits on the tree of life. Now, new analysis of Palaeospondylus’s anatomy might help to solve this mystery.Research article: Hirasawa et al.News and Views: Clues to the identity of the fossil fish Palaeospondylus08:18 Research HighlightsA strong, silk-based version of mother of pearl, and the parrots that use their heads when climbing.Research Highlight: Silk imitates mother of pearl for a tough, eco-friendly materialRes...

How virtual meetings can limit creative ideas
00:56 How video calls can reduce creativityAs a result of the pandemic, workers around the world have become accustomed to meeting colleagues online. To find out if this switch from face-to-face meetings came at a cost to creativity, a team compared the number of ideas generated by workers collaborating either online, or in-person. They showed that people meeting virtually produced fewer creative ideas than those working face-to-face, and suggest that when it comes to idea generation maybe it’s time to turn the camera off.Research article: Brucks & LevavNews and Views: Virtual collaboration hinders idea generationVid...

A fast moving megatrial for coronavirus treatments, and transferring the benefits of exercise by transferring blood
Contributing correspondent Kai Kupferschmidt talks with host Sarah Crespi about the success of a fast moving megatrial for coronavirus treatments. The UK’s RECOVERY (Randomized Evaluation of COVID-19 Therapy) trial has enrolled more than 12,000 hospitalized coronavirus patients since early March and has released important recommendations that were quickly taken up by doctors and scientists around the world. Kai discusses why such a large study is necessary and why other large drug trials like the WHO’s SOLIDARITY trial are lagging behind. Also this week, producer Meagan Cantwell talks with Saul Villeda, a prof...

Hunting for new epilepsy drugs, and capturing lightning from space
About one-third of people with epilepsy are treatment resistant. Up until now, epilepsy treatments have focused on taming seizures rather than the source of the disease and for good reason—so many roads lead to epilepsy: traumatic brain injury, extreme fever and infection, and genetic disorders, to name a few. Staff Writer Jennifer Couzin-Frankel talks with host Sarah Crespi about researchers that are turning back the pages on epilepsy, trying to get to the beginning of the story where new treatments might work.   And Sarah also talks with Torsten Neurbert at the Technical University of Denmark’s Nationa...
