The shifting orbit of one of Saturn’s moons indicates that the satellite has a subsurface ocean, contradicting theories that its interior is entirely solid. The finding calls for a fresh take on what constitutes an ocean moon.

In the first of our annual festive songs celebrating the science of the past year, we pay homage to Ozempic, or Semaglutide, that's able to tackle obesity, diabetes and potentially a whole lot more.

We gather an all-star cast and see how well they can remember some of the big science stories from 2024 in our annual festive quiz.

In the second of our festive songs, we look at CAR-T cells. These engineered immune cells have shown great promise at tackling cancer, but these treatments are not without their drawbacks.

Every year, Nature’s 10 highlights some of the people who have helped shape science over the past 12 months. We hear about a few of the people who made the 2024 list, including an economist who now needs to run a country, a Russian science-sleuth, a researcher who’s been sounding the alarm on Mpox, and a PhD student who won a salary bump for researchers in Canada.

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 changes need to be made to allow this to happen.

We speak to researchers about the history of this naming system, how it’s applied and how it might evolve in the face of growing pressures.

Researchers 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.

A team of scientists have created cellular switches on the surface of cells, allowing them to control their behaviour. Creating these switches has been a long-term goal for synthetic biologists — especially a group of proteins called G-protein-coupled receptors that already control many cellular processes. However, engineering these proteins has been challenging, as modifications can ruin their function. Instead, the team added another molecular component that blocked the receptors activity, but could be removed in response to specific signals. This allowed the researchers to activate these receptors on command, potentially opening up a myriad of new ways to control cell behaviour, such as controlling when neurons fire.

A team at Google has shown it is possible to create a quantum computer that becomes more accurate as it scales up, a goal researchers have been trying to achieve for decades. Quantum computing could potentially open up applications beyond the capabilities of classical computers, but these systems are error-prone, making it difficult to scale them up without introducing errors into calculations. The team showed that by increasing the quality of all the components in a quantum computer they could create a system with fewer errors, and that this trend of improvement continued as the system became larger. This breakthrough could mean that quantum computers are getting very close to realising the useful applications that their proponents have long promised.

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.

Breast 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.

The latest AI system released by OpenAI, the makers of ChatGPT, is better able to break down problems into smaller chunks, making it closer to a human way of solving problems than other systems. This has reignited discussions about the likelihood of AIs achieving human-level intelligence. Although previously the realm of science fiction, researchers are now taking the idea of ‘artificial general intelligence’, or AGI, more seriously. Although this technology has the potential to help tackle humanity's biggest challenges, there are concerns about the safety of such technology if it were to become autonomous.

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. Do any of them actually work?
