Researchers have uncovered a protein that enhances DNA repair and may explain how bowhead whales can live more than 200 years. The protein, cold-induced RNA-binding protein, was shown to enhance repair of double stranded DNA breaks, a particularly troublesome kind of damage. The team showed that this protein could also extend the lives of Drosophila flies and enhance repair in human cells. More needs to be understood about how this protein works, but the researchers hope that it could, one day, help prevent cancer and ageing in humans.

Researchers have used ‘nanobodies’ to create an antivenom that works against 17 snake species’ venom. Snakebites kill millions each year, so getting the right antivenom can be life or death. But they are difficult to produce and often are very specific. Now, using nanobodies from llamas, researchers created an antivenom against a broad range of snake species’ venom. The new antivenom can now even be produced without the llamas, and the team hope it will pave the way for a more universal antivenom.

Researchers have uncovered the neural mechanisms that underlie an aggressive behaviour in mice prompted by hunger and hormonal state. Virgin female mice can become aggressive towards mouse pups when they are food deprived, but it seems that the relevant amounts of pregnancy hormones, oestrogen and progesterone, also played a role. By investigating the neurons involved, neuroscientists showed how hunger and hormones are integrated by the brain to lead to aggressive behaviour. This could help researchers understand more about how multiple stimuli are interpreted by the brain, something much harder to study than single stimulus effects.

A vaccine capable of protecting against multiple strains of avian influenza virus may be a step closer, according to new research. The H5 subtype of avian influenza viruses has spilled over into mammals and is particularly concerning to researchers due to the risk of them evolving to cause another pandemic. But because there are multiple variants of these viruses, it has been hard to pre-prepare vaccines. Now, a team have used information on how these viruses evolved over time to design a vaccine that in animal studies provided protection against different H5 strains. They hope their approach could be applied to create stockpiles of vaccine that could be used in the event of a pandemic, regardless of the strain that causes it.

Stereotyped assumptions about women’s ages and their perceived job suitability are enhanced by Internet imagery, according to new research. A study of hundreds of thousands of online images shows that women appear younger than men. This stereotype extends to the jobs that people perceive women do, with men being associated with roles such as CEO or head of research, while women were linked to occupations like cook or nurse. The research shows that these biases have been embedded into the training data for AI models and could affect future hiring. The researchers caution that society is at risk of creating a ‘self-fulfilling prophecy’ where these stereotypes shape the real world.

Research suggests that ancient viral-DNA embedded in the human genome is playing a key role in early embryo development. Around 8% of our genome consists of endogenous retrovirus DNA — the remnants of ancient infections, but knowledge of their activity is limited.

Researchers have developed a way to use heat to recharge DNA-based computer circuits, which could help overcome one of the stumbling blocks preventing this technology from being scaled up. Although DNA strands have been used to perform computational tasks for some time, current methods can run out of energy or build up waste products, preventing their continued use. Now, using just heat a team have demonstrated a reuseable neural network based on DNA. They hope that ultimately this could be a step in the development of bigger and more powerful DNA computers that could be used to power targeted clinical therapies.

In April, Robert F. Kennedy Jr held a press conference about rising diagnoses of autism, and said he would soon be announcing a study to find the responsible agent. Although Kennedy said that environmental factors are the main cause of autism, research has shown that genetics plays a bigger part. Also, the rise in prevalence, many researchers say, is
predominantly caused by an increase in diagnoses rather than a true rise in the underlying symptoms and traits.
Although the US National Institutes of Health (NIH) announced a US$50 million to fund studies on the causes of autism, many researchers were dismayed that these developments seemed to ignore decades of work on the well-documented rise in diagnoses and on causes of the developmental condition.

Researchers have identified a key protein that helps tick-borne encephalitis virus enter the brain. In rare cases an infection can lead to serious neurological symptoms, but little was known about how the virus interacts with human cells. Now, a team show that a protein found on the outside of cells plays an important role in infection. In mouse experiments, they show that blocking the ability of the virus to bind to this protein protected the mice from disease. Currently no treatments exist, but the team hopes that this research will ultimately lead to a viable drug for this disease.

Researchers have developed an AI tool that can calculate a person’s risk of developing over 1,000 different diseases, sometimes years in advance. The system, called Delphi-2M, was trained to identify patterns of disease progression using 400,000 people's health records from data repository the UK Biobank. This training allowed it to predict someone’s future disease risks, based on their current medical record. While AI health prediction systems do exist, they typically only estimate risks for a single disease — the authors hope that their system could one day save healthcare professionals time and be used to calculate disease burdens at a population level.

In 2015, the Laser Interferometer Gravitational Wave Observatory (LIGO) facilities in the US directly detected ripples in space-time, known as gravitational waves. These waves were produced by the final spiral of two orbiting black holes that smashed into each other, sending ripples across the Universe.
In this podcast, Benjamin Thompson speaks to Cole Miller from the University of Maryland about the quest to detect gravitational waves, which were first hypothesised by Albert Einstein back in 1916.

Major energy producers increased the likelihood and intensity of heatwaves, according to research published in Nature. Using data from an international disaster database, a team developed a methodology to investigate how much anthropogenic climate change had influenced heatwaves. They conclude that many of these events would have been “virtually impossible” without climate change, and that nearly a quarter of the heatwaves recorded from 2000 to 2023 can be directly linked to the greenhouse-gas emissions from individual energy giants.

In 2016, Brian Wansink wrote a blog post that prompted scientific sleuths to investigate his work. They found evidence of data manipulation, and, after several news articles and two investigations by his institution, he would found to have committed misconduct, as defined by Cornell University. His work had been used to inform US policy around food, much of which has now been thrown into question.
Cases like this are rare, but science is not immune to misconduct. The rise in 'paper mills' — organisations that produce questionable or fake papers that they sell authorships on — has led some to worry that misconduct is on the rise and that a proportion of the scientific literature cannot be trusted.
In episode two of Self Correction, we explore how researchers are responding to the problem of research misconduct. We discuss how difficult it is to determine the prevalence of misconduct, and how sleuths, journalists and research integrity institutions are fighting back.

Researchers have made an unusual observation that appears at odds with biology: an ant, known as the Iberian Harvester Ant can produce offspring of two completely different species. Many ants need to mate with other species to produce workers that are a genetic mix of the two, known as hybrids. But in Sicily, a team found hybrid worker ants but no trace of the father. They suggest that the one species present, Messor ibericus, is able to lay its own eggs, but also eggs of another species, Messor structor. These offspring can then mate to produce the hybrid workers. This strategy conflicts with several conventional definitions of what a species is, which may prompt a rethink of these already blurry concepts.

Researchers have discovered that steel truss bridges possess a number of mechanisms that make them resilient to collapse, even after damage. Steel truss bridges are a common kind of bridge, but many are ageing and under increased pressure due to climate change and increased vehicle loads. To understand how damage affects these bridges a team of engineers built a scale replica of a bridge section and monitored how it coped when different sections were cut. They found six distinct resistance mechanisms that allowed the bridge to continue carrying heavy loads even with the damaged sections. They hope these data will help fortify existing bridges and inform the design of future bridges to help prevent catastrophic collapse.

Physicists differ widely in their interpretations of quantum mechanics, and so do Nature readers, according to our Cosmo-inspired quiz. The quantum world is notoriously difficult to explain, with interpretations of the mathematical foundations ranging from the epistemic, which only describes information, to the realist, where equations map onto the real world. The quiz suggests that many readers prefer the realist, even if that is difficult to mesh with the physics itself.

Researchers have used electrochemistry to increase the rates of nuclear fusion reactions in a desktop reactor. Fusion energy promises abundant clean energy, but fusion events are rare, hindering progress. Now, inspired by the controversial claim of cold fusion, researchers used electrochemistry to get palladium to absorb more deuterium ions, that are used in fusion. When a beam of deuterium was fired at the deuterium-filled palladium, they saw a 15% increase in fusion events. They did not get more energy than they put in, but the authors believe this is a step towards enhancing fusion energy and shows the promise of electrochemical techniques.
