Marc Abrahams created the Ig Nobel prizes in 1991, after years of collecting examples of weird research that he included in the Journal of Irreproducible Results. The aim of these satirical awards is to honour achievements that “make people laugh, then think”.While the initial response from the scientific community was mixed, last year the prize received more than 9,000 nominations. Several researchers who have won an ‘Ig’ say that it has improved their careers by helping them to reach wider audiences, and spend more time engaging with the public about their work.This is an audio version of our Feature: How a silly science prize changed my career Hosted on Acast.

Categorizing things is central to science. And there are dozens of systems scientists have created to name everything from the trenches on the sea bed to the stars in the sky.But names have consequences — unintended or otherwise. In our new series What’s in a name we’ll explore naming in science and how names impact the world — whether that’s how the names of storms impact public safety, how the names of diseases impact patient care, or even how the names of scientific concepts can drive the direction of research itself.In this first episode we’re looking at species names. The modern system of species naming began in the 1700s and has played a vital role in standardizing academic communication, ensuring that scientists are on the same page when they talk about an organism. However, this system is not without its issues. For example, there has been much debate around whether species with names considered offensive — such as those named after historical racists — should be changed, and what rule chang

00:45 A potential treatment for pre-eclampsiaResearchers have shown in mice experiments that an mRNA-based therapy can reverse the underlying causes of pre-eclampsia, a deadly complication of pregnancy for which treatment options are limited. Inspired by the success of mRNA vaccines, the team behind the work designed a method to deliver the genomic instructions for a blood-vessel growth factor directly into mouse placentas. This stimulated the production of extra blood vessels reducing the very high-blood pressure associated with the condition. Pre-eclampsia causes 15% of maternal deaths and 25% of foetal and newborn deaths worldwide and although the work is early and human trials will be required, the team hope that this work demonstrates the potential of using this approach to treat pre-eclampsia.Research Article: Swingle et al.11:00 Research HighlightsStacks of, mass-produced bowls suggest that people founded, but then abandoned an ancient Mesopotamian civilization, and analysis of Venus’s gases suggests t

Zoologist Arik Kershenbaum has spent his career studying animals and how they communicate in the wild. In his book Why Animals Talk: The New Science of Animal Communication, Arik takes a deep dive into the various forms of communication, from wolf howls to gibbon songs, to look at how different species get their points across, why they do it the way they do, and what insights they provide into our own use of language.Why Animals Talk: The New Science of Animal Communication Arik Kershenbaum Penguin (2024)Music supplied by SPD/Triple Scoop Music/Getty ImagesWolf howl via NPS & MSU Acoustic Atlas/Jennifer JerrettSlowed down dolphin whistle via Arik KershenbaumHyrax song via Arik KershenbaumPileated gibbon song via Rushenb CC BY-SA 4.0 Hosted on Acast.

00:48 Chemotherapy efficacy varies with the menstrual cycleBreast cancer cells are more susceptible to chemotherapy at certain points in the menstrual cycle, new data in Nature suggests. Researchers studied the equivalent hormonal cycle in mice and found that during the oestrous phase, where progesterone levels are low, tumours are more susceptible to chemotherapy. The same effect was shown in humans in a small retrospective study. The team caution that a larger clinical trial would need to be conducted, but hope that this work could open up an, easy to implement, way to boost the effect of chemotherapy.Research Article: Bornes et al.News and Views: What is the best time of the month to treat breast cancer?09:22 Research HighlightsHow coffee changes your gut microbiota, and the first amber deposits found in Antarctica hint at an ancient rainforest.Research Highlight: Do you drink coffee?

AI tools that help researchers design new proteins have resulted in a boom in designer molecules. However, these proteins are being churned out faster than they can be made and tested in labs.To overcome this, multiple protein-design competitions have popped up, with the aim of sifting out the functional from the fantastical. But while contests have helped drive key scientific advances in the past, it's unclear how to identify which problems to tackle and how best to select winners objectively.This is an audio version of our Feature: AI has dreamt up a blizzard of new proteins.

00:50 Fossilised faeces give news insights into dinosaurs’ diets and riseA huge collection of fossilised digestive contents has provided clues as to how dinosaurs grew to become the dominant animals on the planet. Why these animals rose to dominance has been unclear, with one theory proposing that a chance event wiped out other species, whereas another suggests that dinosaurs had adaptations that better allowed them to thrive. By analysing over 500 vomit and faeces fossils, researchers have better identified what dinosaurs ate, and their interactions with other animals. The new work suggests both of these theories are correct, with dinosaurs benefiting from one or the other at different points in time. The researchers believe this work demonstrates how useful fossilised food contents are for understanding these ancient creatures.Research Article: Qvarnström et al.News and Views: Wastes of time — faeces and vomit track how dinosaurs rose to prominenceNews: Fossilized poo and vomit shows how dinosaurs rose to r

00:45 A squid-inspired device for needle-free drug deliveryInspired by squids’ ability to shoot ink, a team of researchers have developed swallowable devices that can deliver tiny jets of drugs directly into the gut lining, circumventing the need for needles. Previous studies have shown that most people prefer to take medication in pill form, rather than as an injection, but many drugs are degraded as they pass through the digestive system. The team’s new swallowable devices overcome this issue, and deliver drugs directly to where they need to be. So far, this approach has shown efficacy in animal models, but more work needs to be done to ensure their safety in humans.Research Article: Arrick et al.10:50 Research HighlightsThe largest ‘terror bird’ fossil ever found, and a simple solution to help prevent premature births.Research Highlight: Huge carnivorous ‘terror bird’ rivalled the giant panda in sizeResearch Highlight: Reducing pregnancy risk could be as easy as chewing gum12:52 A milder way to break down

00:46 The role of skull bone marrow in ageingDuring ageing, bone marrow in the skull becomes an increasingly important site of blood-cell production. This is in stark contrast to most bones where the ability of marrow to make blood and immune cells declines. Studies in mice and humans showed that ageing results in skull bone-marrow expanding, and in mice this marrow was more resistant to inflammation and other hallmarks of ageing. The team behind the work hope by understanding this process better it may be possible to help organs become more resistant to ageing.Research Article: Koh et al.08:56 Research HighlightsElderly big brown bats show remarkable resistance to age-related hearing loss, and why search-engine algorithms may not be the main driver steering people towards misinformation.Research Highlight: No hearing aids needed: bats’ ears stay keen well into old ageResearch Highlight: Don’t blame search engines for sending users to unreliable sites11:38 How to make lead a useful material to date the Solar

00:46 Mitochondria divide their labour to help cells thriveResearchers have uncovered that mitochondria divide into two distinct forms when cells are starved, a finding that could help explain how some cancers thrive in hostile conditions. Mitochondria are cellular powerhouses, creating energy and vital metabolic molecules, but how they are able to do this when resources are limited has been a mystery. It turns out that in nutrient-poor situations, mitochondria split into two separate types, one which concentrates on energy production, the other on producing essential cellular building blocks. Together these allow cells to make everything they need. The team showed that this also happens in certain cancer cells, which may help them survive and grow under hostile conditions in the body.Research Article: Ryu et al.News and Views: Division of labour: mitochondria split to meet energy demandsVideo: A new kind of mitochondrion07:53 Research HighlightsA tidy genome may explain naked mole rats’ long lifespans, and w
