Anecdotal stories suggesting that weight-loss drugs can help people shake long-standing addictions have been spreading fast in the past few years, through online forums, weight-loss clinics and news headlines. And now, clinical data are starting to back them up.

Over a dozen randomized clinical studies testing whether GLP-1 drugs like Ozempic can suppress addiction are now under way, and neuroscientists are working out how these weight-loss drugs act on brain regions that control craving, reward and motivation.

Scientists warn that the research is still in its early stages, but some researchers and physicians are excited, as no truly new class of addiction medicine has won approval from regulators in decades.

Researchers have created a ‘pangenome’ containing the genomes of multiple potato types, something they believe can help make it easier to breed and sequence new varieties. The potato’s complicated genetics has made it difficult to sequence the plant’s genome, but improvements in technology have allowed the team to combine sequences, allowing them to look for subtle differences in between varieties.

According to legend, physicist Werner Heisenberg formulated the mathematics behind quantum mechanics in 1925 while on a restorative trip to the remote North Sea island of Heligoland.

To celebrate the centenary of this event, several hundred researchers have descended on the island to take part in a conference on all things quantum physics. Nature reporter Lizzie Gibney was also in attendance, and joined us to give an inside track on the meeting.

Researchers have developed two compounds that can kill malaria-causing parasites within mosquitoes, an approach they hope could help reduce transmission of the disease. The team showed that these compounds can be embedded into the plastics used to make bed nets, providing an alternative to insecticide-based malaria-control measures, which are losing efficacy in the face of increased resistance.

Samples taken from the asteroid Bennu by NASA's OSIRIS-REx spacecraft suggest the parent body it originated from is likely to have contained salty, subsurface water. This finding provides insights into the chemistry of the early Solar System, and suggests that brines might have been an important place where pre-biotic molecules were formed.

Cells are often grouped into categories according to the RNA molecules they produce. However a study of zebrafish (Danio rerio) brains revealed that cells can be functionally diverse even if they appear molecularly similar. This finding adds more nuance to how a cell's ‘type’ is ultimately defined.

An assessment of death rates in India’s coastal megacity of Mumbai revealed that the impact of extreme rainfall events will be highest for women, young children and residents of informal settlements. This situation is likely to become more pronounced as a result of climate change.

Inspired by animals like barnacles and aided by machine learning, researchers have developed a super-sticky compound that works as an underwater adhesive. To demonstrate its properties, researchers applied it to a rubber duck, which stuck firmly to a rock on a beach despite being battered by the sea.

Baked soil, ancient tools, and materials that could be used to start fires show that Neanderthals were making fire in the UK 400,000 years ago — the earliest evidence of this skill found so far. Ancient humans are known to have used naturally occurring fires, but evidence of deliberate fire-starting has been hard to come by. A new suite of evidence pushes back the date of fire mastery by 350,000 years. The team behind the finding believe it helps create a more nuanced picture of Neanderthals, who perhaps gathered round fires and told stories in ancient Europe.

Research suggests that artificial-intelligence chatbots can influence voters’ political views and have a bigger effect than conventional campaigning and advertising. One study found that chatbot conversations swung participants’ candidate preferences by up to 15 percentage points, while another revealed that the chatbots’ effectiveness stems from their ability to synthesize a lot of information in a conversational way.

The ability of space-based telescopes to image the distant Universe could be in peril, according to new research investigating the impacts of light-pollution from future satellites. Streaks of reflected light from satellites currently in low-Earth orbit are already seen in telescope images, and planned launches could raise the number of satellites from around 15,000 to over half-a-million. Computer modelling revealed that this drastic increase would result in images taken by instruments like the Hubble Space Telescope becoming unusable by astronomers. The team propose a series of strategies to help mitigate these impacts, preventing this future becoming reality.

Glitches in video calls are an annoying feature of everyday life, but these brief interruptions could have serious real-world impacts, according to analysis from a team of researchers. In one experiment, the team found that video calls with glitches decreased the likelihood of someone being hired for a job. Analysis of other data suggested glitchy calls were associated with lower chances of individuals being granted parole. The team behind the work think that these visual errors break the illusion that a video call is a real face-to-face conversation, potentially impairing judgements about the quality of the information discussed.

CRISPR-based gene editing has revolutionized modern biology, but these tools are unable to access the DNA that resides inside mitochondria. Researchers are eager to access and edit this DNA to understand more about the energy production and the mutations that can cause incurable mitochondrial diseases.

Because CRISPR can’t help with these problems, researchers have been looking for other ways to precisely edit the mitochrondrial genome. And the past few years have brought some success — if researchers can make editing safe and accurate enough, it could eventually be used to treat, and even cure, these genetic conditions.

The sounds of ‘micro-lightning’ have been recorded by NASA’s Perseverance rover, ending a long search for the phenomenon on Mars. A lack of suitable equipment has made it difficult to gather evidence of lightning on the red planet, but a team of researchers realized that a microphone on Perseverance should be able to pick up the characteristic sounds of electrical discharges. In total they found 55 such examples, along with signs of electrostatic interference indicative of the phenomenon. They dubbed the electric bursts ‘micro-lightning’, as they are far smaller than the lighting seen on Earth, due to the thin Martian atmosphere. The team believe this finding could help better understand Martian chemistry and how best to design equipment to explore the planet’s surface.

A new analysis suggests that female authors retract fewer medical science papers than their male counterparts. Women are known to be underrepresented in the medical sciences, but even accounting for this an AI-tool revealed that female authors featured on far fewer retracted research articles. Reporter Jenna Ahart has been investigating and told us why this might be, and what it means for research more broadly.
