In the early days of the pandemic, researchers raced to identify the most potent antibodies produced by the immune system in response to SAR-COV-2 infection and produce them in bulk. The resulting ‘monoclonal antibodies’ have since been tested in a variety of settings as treatments for COVID-19.But despite promising clinical trial results and several therapies having already been approved, antibody therapies have not yet played a large role in the fight against COVID-19. In this episode of Coronapod, we ask why.News: COVID antibody treatments show promise for preventing severe diseaseNews: Antibody therapies could be a bridge to a coronavirus vaccine — but will the world benefit?Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.

A computer that can participate in live debates against human opponents.In this episode:00:43 AI DebaterAfter thousands of years of human practise, it’s still not clear what makes a good argument. Despite this, researchers have been developing computer programs that can find and process arguments. And this week, researchers at IBM are publishing details of an artificial intelligence that is capable of debating with humans.Research Article: Slonim et al.News and Views: Argument technology for debating with humans10:30 Research HighlightsThe sea slugs that can regrow their whole body from their severed head, and evidence of high status women in ancient Europe.Research Highlight: Now that’s using your head: a sea slug’s severed noggin sprouts a new bodyResearch Highlight: A breathtaking treasure reveals the power of the woman buried with it12:56 Briefing ChatWe discuss some highlights from the Nature Briefing.

Since the beginning of the pandemic, there have been many open questions about how COVID-19 could impact pregnant people and their babies – confounded by a lack of data.But now, studies are finally starting to provide some answers. While it does seem that pregnancy is associated with an increased risk of hospitalisation, babies appear to be spared from severe illness in most cases.In this week’s Coronapod we talk about these findings, and the questions that remain – including whether vaccines are safe to give to pregnant people.News: Pregnancy and COVID: what the data say Hosted on Acast.

Physicists examine the gravitational pull between two tiny masses, and how fossil lampreys could shake-up the field of vertebrate evolution.In this episode:00:47 Gravity, on the small scaleThis week, researchers have captured the smallest measurement of gravity on record, by measuring the pull between two tiny gold spheres. This experiment opens the door for future experiments to investigate the fundamental forces of nature and the quantum nature of gravity.Research Article: Westphal et al.News and Views: Ultra-weak gravitational field detected07:37 Research HighlightsResearch shows that people often don’t know when a conversation should end, and the cuttlefish that show remarkable self control.Research Highlight: How long should a conversation last? The people involved haven’t a clueResearch Highlight: Arms control: cuttlefish can pass the ‘marshmallow test’10:18 Lamprey evolutionThe larval stage of lamprey growth has long been thought to resemble the kind of early animal that all vertebrates evolved from. However, new research looking at the fossils of lamprey species suggests that this popular hypothesis may be incorrect.Research Article: Miyashita et al.17:38 Briefing ChatWe discuss some highlights from the Nature Briefing.

Where did the SARS-CoV-2 virus come from? As a team of researchers from the WHO prepares to report on its investigation into the origins of the virus, we discuss the leading theories, including the controversial ‘lab leak' hypothesis.Although there is no evidence to support it, the lab-leak idea remains popular among certain groups. Similar hypotheses were even touted about the Ebola outbreak in Sierra Leone. We discuss why theories like this seem to gain traction.News: ‘Major stones unturned’: COVID origin search must continue after WHO report, say scientistsNews: Where did COVID come from?

The pandemic's unequal toll on the research community, and a newly discovered mitochondria-like symbiosis.In this episode:00:48 The pandemic's unequal toll on researchersAlthough 2020 saw a huge uptick in the numbers of research papers submitted, these increases were not evenly distributed among male and female scientists. We look at how this could widen existing disparities in science, and damage future career prospects.Editorial: COVID is amplifying the inadequacy of research-evaluation processes09:18 Research HighlightsHow a parasite can make viral infections more deadly, and the first known space hurricane.Research Highlight: Intestinal worms throw open the door to dangerous virusesResearch Highlight: The first known space hurricane pours electron ‘rain’11:36 Energy without oxygenMillions of years ago, a microscopic protist swallowed a bacterium and gained the ability to breathe nitrate.

Researchers in Japan are trying to understand why thunderstorms fire out bursts of powerful radiation.Gamma rays – the highest-energy electromagnetic radiation in the universe – are typically created in extreme outer space environments like supernovae. But back in the 1980s and 1990s, physicists discovered a source of gamma rays much closer to home: thunderstorms here on Earth.Now, researchers in Japan are enlisting an army of citizen scientists to help understand the mysterious process going on inside storm clouds that leads to them creating extreme bursts of radiation.This is an audio version of our feature: Thunderstorms spew out gamma rays — these scientists want to know why Hosted on Acast.
