2023/11/22

In this episode:00:46 What happens after polio is eradicatedSince 1988, cases of polio have fallen by more than 99%, and many observers predict that the disease could be eradicated within the next three years. However, eradication isn’t the same as extinction, so the next challenge is for researchers to make sure the disease won’t return. We discuss what a post-polio future may look like, and how to ensure that the disease is gone for good.News Feature: Polio is on the brink of eradication. Here's

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

In this episode:00:46 Modifying a fungal drug to make it less toxicAmphotericin B is a drug used to treat life-threatening fungal infections. But while it is effective against many fungal species, it is also extremely toxic to kidneys, meaning it is mostly used as a drug of last-resort. This week, a team has unpicked the mechanism behind the drug’s toxicity, allowing them to modify it and reduce side effects in human kidney cells. The researchers hope this new version of the drug could become a

Now, researchers have developed a material that can be directly injected into injured muscle, helping to stimulate and heal damaged tissue. The team showed this approach could rapidly restore walking ability in severely injured rats and regenerate muscles within four weeks.

For years, researchers have been listening to Mars and the quakes that ripple through it, to understand the planet's internal structure and uncover its history. But often these results have left more questions than answers. Now, though, new research published in Nature reveals the composition and size of Mars's core, finding that it is much smaller than previously thought.Research Article: Khan et al.Research Article: Samuel et al.News and Views: Deep Mars is surprisingly softSubscribe to Nature

In this episode:00:47 An automated way to monitor wildlife recoveryTo prevent the loss of wildlife, forest restoration is key, but monitoring how well biodiversity actually recovers is incredibly difficult. Now though, a team have collected recordings of animal sounds to determine the extent of the recovery. However, while using these sounds to identify species is an effective way to monitor, it’s also labour intensive. To overcome this, they trained an AI to listen to the sounds, and found that

In this episode:00:47 An RNA-based viral system that mimics bacterial immune defencesTo protect themselves against viral infection, bacteria often use CRISPR-Cas systems to identify and destroy an invading virus’s genetic material. But viruses aren’t helpless and can deploy countermeasures, known as anti-CRISPRs, to neutralise host defences. This week, a team describe a new kind of anti-CRISPR system, based on RNA, which protects viruses by mimicking part of the CRISPR-Cas system. The researchers

Using CRISPR, a team made dozens of edits to the pig genome to prevent the monkeys’ immune system from attacking the organs. They also removed pig retrovirus genes that could represent an infection risk. These steps are necessary if pig organs are to be used in human

This species lives in wetlands that are under threat due to rising temperatures and a reduction in rainfall.In an effort to save the tortoise, researchers are trialling a controversial strategy called assisted migration. This approach has seen captive-bred tortoises released in other wetlands some 330 kilometres south of where they are naturally found.

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

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

In this episode:00:47 First observation of oxygen 28Oxygen 28 is an isotope of oxygen with 20 neutrons and eight protons. This strange isotope has long been sought after by physicists, as its proposed unusual properties would allow them to put their theories of how atomic nuclei work to the test. Now, after decades of experiments physicists believe they have observed oxygen 28. The observations are at odds with theory predictions, so they imply that there’s a lot more physicists don’t know about the

Investigations suggest that, in some fields, at least one-quarter of clinical trials might be problematic or even entirely made up. Faked or unreliable trials are dangerous, as they could end up being included in the reviews that help inform clinical treatments. However, the extent of the problem in unclear, and many researchers urge stronger scrutiny.This is an audio version of our Feature: Medicine is plagued by untrustworthy clinical trials.
