News from Science, September 3

The dominant theme in early September 2026 is science moving simultaneously towards much larger observational systems and much finer biological resolution. Roman will survey billions of galaxies, LZ is searching for extraordinarily rare particle interactions, and millennium-long climate records are revealing changes that cannot be seen in modern measurements alone. At the opposite scale, researchers are rewriting genomes nucleotide by nucleotide and discovering previously unknown forms of RNA and protein production.

A second trend is the growing fusion of medicine, molecular biology and computational science. GLP-1 drugs are being investigated far beyond their original metabolic indications, previously “undruggable” cancer pathways are becoming therapeutic targets, and AI is entering genomics and laboratory research — while experiments are simultaneously exposing the limits of current AI models.

Climate science is also entering a new phase. The debate is increasingly shifting from whether the world can completely avoid 1.5°C of warming to how far temperatures will overshoot it, for how long, and how societies can adapt while continuing rapid emissions reductions. Finally, Romania’s latest initiatives show a similar strategic movement at national level: towards quantum technologies, research–industry networks, technology transfer and integration into European research ecosystems.

Romania launches a RON 16 million programme to build a national quantum-technology ecosystem

Romania’s National Authority for Research, through the Institute of Atomic Physics at Măgurele, has opened the 2026 competition for the RAQTRO project, aimed at strengthening the country’s quantum-technology ecosystem. The programme has a total budget of RON 16 million and is designed to connect universities and research institutes with industry, public authorities and education. Its scope covers quantum computing, quantum communications and sensing, as well as post-quantum cryptography, in line with Romania’s National Quantum Technologies Strategy 2024–2029. Expressions of interest are being accepted until 7 September, with final results expected on 15 October. Although the programme emphasizes ecosystem-building and awareness rather than construction of a quantum computer, it is significant because it seeks to create the human, institutional and collaborative infrastructure needed for Romania to participate more substantially in Europe’s rapidly expanding quantum sector.

Romania puts new money into innovation clusters and links research more closely to European networks

The National Authority for Research has launched a new PNCDI IV competition for the organization and development of innovation clusters. The programme has a budget of RON 2.85 million, can finance up to 18 projects, and provides a maximum of RON 450,000 per project over three years. Its importance lies less in the size of the funding than in its model: research organizations, companies and other innovation actors are being encouraged to share resources, establish common R&D objectives and connect Romanian clusters with European and international value chains. Applications remain open until 30 September, with evaluations scheduled for the final quarter of 2026. Together with Romania’s recent programmes for technology transfer, diaspora researchers and quantum science, the initiative indicates a broader shift from financing isolated research projects towards building networks capable of turning scientific results into technologies and economic applications.

A single unexplained event could be the first experimental hint of dark matter

The LUX-ZEPLIN (LZ) experiment, located about 1.6 kilometres underground in South Dakota, has detected a particle interaction whose properties resemble those expected from a WIMP — weakly interacting massive particle, one of the leading candidates for dark matter. The detector contains about ten tonnes of ultrapure liquid xenon and searches for extremely rare collisions between hypothetical dark-matter particles and xenon nuclei. Researchers stress that they have observed only one event and therefore cannot claim a discovery; alternative explanations and unidentified background signals must still be eliminated. Nevertheless, scientists involved in LZ describe it as possibly the most intriguing direct-detection signal yet. Because dark matter is thought to constitute roughly 85% of the Universe’s matter, confirmation by further events would represent one of the most important discoveries in modern physics. (Reuters)

NASA launches the Nancy Grace Roman Space Telescope, opening a new era of panoramic astronomy

NASA successfully launched its roughly US$4-billion Nancy Grace Roman Space Telescope aboard a SpaceX Falcon Heavy. The observatory is travelling towards the Sun–Earth L2 region, about 1.6 million kilometres from Earth, where it will undergo approximately 90 days of commissioning. Roman combines Hubble-like sensitivity and resolution with an enormously larger field of view: NASA scientists estimate that it could survey the Milky Way in about a month, whereas a comparable Hubble survey would require roughly a century. Its major objectives include creating an unprecedented three-dimensional map involving more than two billion galaxies, studying dark energy and dark matter, testing gravity on cosmic scales and discovering potentially thousands of exoplanets through gravitational microlensing. Roman therefore complements the deep but narrower observations of JWST and could transform both cosmology and planetary science. (Reuters)

UN analysis concludes that the world will pass the long-term 1.5°C climate threshold

A new United Nations Environment Programme assessment marks an important change in climate-policy language: limiting long-term global warming to 1.5°C above pre-industrial levels is no longer considered realistically achievable. According to the analysis reported by Nature, the long-term temperature average is expected to cross the threshold before the end of this decade. On the present trajectory, UNEP estimates that warming of around 1.8°C this century is now approximately the best outcome that could be achieved, assuming stronger mitigation efforts. The distinction between temporarily exceeding 1.5°C in individual years and breaching it as a long-term climatic average remains important, but the scientific message is increasingly focused on limiting the magnitude and duration of the overshoot rather than preventing it altogether. Every additional tenth of a degree substantially increases risks to ecosystems, health, agriculture and extreme-weather exposure. (Nature)

A 1,000-year coral record suggests human-caused warming is making strong El Niño events more frequent

Researchers have reconstructed approximately a millennium of eastern Pacific sea-surface temperatures using coral skeletons from the Galápagos Islands. The record, published in Science, provides some of the strongest evidence so far that the frequency of powerful El Niño events during the past century is unusual compared with the pre-industrial millennium. This supports climate-model projections indicating that anthropogenic warming is altering the behaviour of the El Niño–Southern Oscillation rather than merely raising average temperatures. The result is particularly relevant in 2026 because another strong El Niño developed during the summer and could become exceptionally intense. Strong El Niños affect rainfall, drought, wildfires, marine ecosystems, agriculture and temperatures across much of the planet. The research therefore strengthens the connection between global warming and changes in the variability — not merely the average state — of Earth’s climate system. (Nature)

Scientists discover that mammalian genes can combine to produce previously unknown functional proteins

A study published in Nature has revealed an unexpectedly large layer of genetic complexity. Researchers found that pieces of different genes — sometimes located on separate chromosomes — can combine to form chimeric messenger RNAs, which can then encode functional proteins. The team identified more than 30,000 candidate chimeric mRNAs and examined hundreds whose production changed during immune responses. One experimentally studied chimera in mice influenced inflammatory signalling and resistance to bacterial infection. Until now, chimeric transcripts were often treated mainly as abnormalities associated with cancer or errors in gene expression. The new findings suggest that at least some are normal, regulated components of mammalian biology. If confirmed broadly in humans, they could substantially enlarge the known functional proteome and reveal previously invisible drug targets in immunity, cancer, neurodegeneration and inflammatory disease.

Semaglutide extends lifespan and improves late-life health in female mice

The scientific debate over GLP-1 medicines has moved beyond obesity and diabetes into ageing biology. A study published in Nature found that older female mice receiving semaglutide lived longer and displayed slower progression of several biological characteristics associated with ageing. The results are particularly interesting because treatment began relatively late in life, raising the possibility that some ageing-related processes remain pharmacologically modifiable after they are already established. However, this is emphatically not evidence that semaglutide is an anti-ageing treatment for humans: effects on human lifespan have not been demonstrated, the study involved mice, and sex-specific effects require further investigation. What makes the finding important is the convergence of obesity research, metabolism and geroscience. Researchers are increasingly testing whether drugs developed for common diseases can modify broader biological pathways associated with ageing and multiple age-related disorders simultaneously.

A pancreatic-cancer breakthrough shows promise against lung cancer

Daraxonrasib, a new drug targeting the notoriously difficult RAS family of cancer-driving proteins, is emerging as one of the more important oncology developments of 2026. Only days after US approval for advanced pancreatic cancer, early clinical results showed that tumours shrank in more than 30% of participants with non-small-cell lung cancer. Daraxonrasib works through an unusual “molecular glue” mechanism: it binds cyclophilin A to form a complex capable of blocking both normal and mutant RAS proteins. RAS mutations are common in pancreatic, lung and colorectal cancers and were considered essentially “undruggable” for decades. In an earlier trial involving about 500 patients with advanced pancreatic cancer, daraxonrasib nearly doubled average survival, from 6.7 months with standard chemotherapy to 13.2 months. Larger studies are still necessary, but success across several tumour types could establish a genuinely new class of broad-spectrum targeted cancer therapies. (Nature)

Mutating almost every letter of an entire genome reveals how much biology — and AI — still fails to understand

Researchers systematically altered almost every nucleotide of the tiny bacteriophage ΦX174 genome, creating more than 44,000 genetic variants and measuring how each mutation affected the virus. Around half of single-nucleotide substitutions and 60% of amino-acid changes reduced viral fitness. More strikingly, scientists could not explain why roughly one-quarter of lethal mutations were lethal, despite ΦX174 being among the best-studied organisms in molecular biology. Leading biological AI models also struggled to predict many of the experimentally observed effects. The work is significant because genome-focused AI systems are increasingly proposed for drug discovery, synthetic biology and genetic engineering. It shows that impressive computational models remain constrained by gaps in experimental biological knowledge. Rather than replacing laboratory science, AI may therefore make large, systematic experimental datasets even more valuable. (Nature)
