Events

January

February

  • 12 February
    • Using observations by ESA's CHEOPS telescope, scientists describe a unique configuration of a planetary system around the star LHS 1903, where the innermost and outermost planets are rocky, while the two middle planets have extended atmospheres. This provides support for the "inside-out" model of planet formation.[37][38][39][40]
    • A small polymerase ribozyme is described which can synthesize both its complementary strand and a copy of itself. This is interpreted as a substantial support for the "RNA world" hypothesis of the origin of life.[41][42]
    • Researchers at Iceberg Quantum publish a study describing the "Pinnacle Architecture", a fault-tolerant quantum computing design based on quantum low-density parity-check (qLDPC) codes. They show that a 2048-bit RSA integer could be factored with fewer than 100,000 physical qubits under standard hardware assumptions – an order-of-magnitude reduction compared to previous estimates.[43][44]
  • 24 February – Researchers in Switzerland report that centenarians show "youthful" blood profiles across 37 proteins, including markedly lower oxidative stress markers, suggesting that specific aging-related biological pathways are slowed in exceptional longevity.[45]
  • 26 February – Researchers in Australia report that serum bicarbonate levels in U.S. population data have risen by 7% since 1999, tracking increases in atmospheric carbon dioxide. Modelling suggests that, if current trends continue, average bicarbonate levels could approach the upper limit of today's accepted healthy range within 50 years.[46][47]

March

  • 6 March
    • Astronomers report the discovery of GJ 887 d, a super-Earth exoplanet orbiting the nearby red dwarf star GJ 887. Detected using radial velocity measurements, the planet lies within the star's habitable zone. At just 10.7 light-years, this becomes the second-nearest known exoplanet in the habitable zone after Proxima Centauri b.[48]
    • The UK's first long‑distance robotic-assisted surgery is reported to have been performed on a patient located 1,500 miles (2,400km) away in Gibraltar.[49]
  • 9 March – A study published in Geophysical Research Letters reports with statistical confidence that global warming has accelerated since around 2015, with the rate of increase rising from 0.2 °C to about 0.35 °C per decade after accounting for natural variability. The findings suggest the 1.5 °C threshold could be reached before 2030 if current trends continue.[50]
  • 10 March – A study by Vattenfall and Spoor using AI-assisted video monitoring of 2,007 bird flight paths near an offshore turbine at Aberdeen Bay over 19 months reports no confirmed collisions, with observed avoidance behaviour suggesting lower-than-expected impacts of wind turbines on seabirds.[51]
  • 11 March
    • Two separate studies, published in Environmental Research Letters and Nature Communications, show how net negative emissions will need to be sustained for centuries in order to stabilise global climate change.[52]
    • Astronomers report evidence of a likely collision between two planets orbiting the star Gaia20ehk, about 11,000 light years away in the constellation Puppis. Erratic dimming and strong infrared emission are attributed to hot debris produced by the impact passing in front of the star.[53]
  • 12 March – An international team reports the first direct measurements of the nanomechanical properties of lithium dendrites, microscopic needle-like structures that can form inside lithium batteries and cause them to short circuit or catch fire. The study finds that dendrites are strengthened by a solid electrolyte interphase layer, making them brittle and capable of penetrating battery separators, providing new insight into battery degradation and safety risks.[54]
  • 17 March – Physicists at CERN's LHCb experiment report the discovery of the doubly charmed baryon Ξcc⁺. The particle, containing two charm quarks and one down quark, is detected with high statistical significance and resolves a long-standing discrepancy from earlier experimental results.[55][56]
  • 18 March – Charles H. Bennett and Gilles Brassard are awarded the 2025 Turing Award for their work in quantum information science.[57]
  • 20 March – Scientists from Great Ormond Street Hospital and University College London report the creation of the first lab‑grown oesophagus, and show it can safely replace a full section of the organ and restore normal function, including swallowing, in a growing animal without the need for immunosuppression.[58][59]
  • 24 March
    • Antimatter particles are transported by road for the first time, to assess their stability during transit. An estimated 100 to 1,000 antiprotons are carried in a Penning trap across a distance of five kilometres in Switzerland.[60][61]
    • A 20-year Japanese study published in Nature Communications reports that repeated cloning of laboratory mice from a single donor could not continue beyond 58 generations, after large structural and lethal DNA mutations accumulated and birth rates declined from the 27th generation.[62][63]
  • 25 March – Astronomers identify a shortlist of 45 nearby exoplanets as the most promising candidates for habitability, based on their size, composition, and location within their stars' habitable zones. The catalogue is intended to guide future observations by next-generation telescopes in the search for biosignatures and extraterrestrial life.[64]
  • 27 March – Researchers led by the University of Oxford report a synthetic biology approach to improving honeybee nutrition, engineering yeast to produce essential sterols missing from modern diets. Colonies fed the supplement produce up to 15 times more developing young.[65]

April

April 1: Artemis II blasts off toward the Moon for its lunar flyby, carrying a crew of four.
  • 1 April – Artemis program: NASA[66] launches the Artemis II lunar flyby mission from Launch Complex 39B at the Kennedy Space Center in Florida, the first crewed flight beyond low Earth orbit since Apollo 17 in 1972. With a crew of four astronauts – Reid Wiseman (Commander) Victor Glover (Pilot), Christina Koch (Mission specialist), and Canadian astronaut Jeremy Hansen (Mission specialist)[67] – it also becomes the first time a person of color, a woman, and a non-United States citizen have left low Earth orbit.[68] It passed around the Moon's far side on April 6.
  • 2 April
  • 6 April – In a landmark achievement for India's nuclear energy programme, the 500 MWe Prototype Fast Breeder Reactor successfully attains first criticality (start of controlled fission chain reaction).[71]
  • 6 April – The crew of Artemis II breaks the record for the furthest humans have ever been from Earth, reaching a maximum distance of 252,757 miles (406,773 km) as they travel around the far side of the Moon.[72]
  • 8 April
    • A systematic review and meta-analysis published in PLOS ONE reports that regular physical activity is associated with a 25% lower risk of dementia, while prolonged sedentary behaviour (more than 8 hours of sitting per day) is associated with a 27% higher risk. Sleeping less than 7 hours or more than 8 hours per night is likewise linked to increased dementia risk.[73][74]
    • Blue Origin reports that its "Air Pioneer" reactor has extracted oxygen from melted lunar regolith simulant, yielding medical- and propellant-grade oxygen via purification of gases released during electrolysis. The system is being developed as part of the company's in situ resource utilization efforts for sustainable lunar exploration.[75][76]
  • 9 April – The first non-mammalian synapsid fossil embryo belonging to Lystrosaurus is described, confirming the hypothesis that mammal ancestors laid eggs.[77]
  • 13 April – A study published in the Journal of Competition Law & Economics finds that AI-driven personalised pricing could allow firms to charge different prices to individual consumers based on predicted willingness to pay, raising concerns about transparency, fairness, and potential abuse of dominant market positions under EU and UK competition law.[78][79]
  • 15 April – A study published in Science Advances finds that the Atlantic meridional overturning circulation (AMOC) is likely to weaken by 42–58% by 2100, significantly more than many previous estimates, with the most realistic climate models indicating a high probability of eventual collapse. The research reduces uncertainty by combining observational data with model projections, suggesting that stronger slowdown scenarios are more consistent with real-world conditions. Scientists warn that such a decline could have major impacts on global climate systems, including shifts in rainfall patterns, rising sea levels in the Atlantic, and extreme weather changes in Europe and other regions.[80][81]
  • 16 April – A study in the Journal of Geophysical Research: Planets presents "PlanetWaves", a model developed by researchers at MIT to predict wave formation under different planetary conditions. The results suggest that wave behaviour varies widely depending on gravity, atmosphere, and liquid composition, with gentle winds potentially generating large waves on Titan but only small ripples on denser or higher-gravity worlds.[82][83]
  • 17 April – A study in the Journal of Nutrition finds that egg consumption is associated with a lower risk of Alzheimer's Disease for those aged 65 and older. Eating one egg per day for at least five days a week reduces risk of Alzheimer's by up to 27%, researchers found.[84][85]
  • 21 April – The discovery of seven previously undetected organic molecules (trimethylbenzene, tetramethylbenzene, methyl benzoate, dihydronaphthalene, naphthalene, benzothiophene and methylnaphthalene) on Mars by the Curiosity rover is announced.[86]
  • 28 April – Astronomers using data from the Transiting Exoplanet Survey Satellite report 11,554 exoplanet candidates, including 10,091 new candidates, from a machine-learning-assisted search of 83.7 million stellar light curves. One candidate, TIC 183374187 b, is confirmed as a hot Jupiter.[87]

May

  • 3 May – Astronomers from the University of Warwick report 118 new confirmed exoplanets, with a further 2,000 "high-quality" candidates, detected using machine learning applied to data from NASA's Transiting Exoplanet Survey Satellite (TESS).[88]
  • 4 May
    • The discovery of a thin atmosphere on the trans-Neptunian object (612533) 2002 XV93 is announced.[89]
    • A study published in Communications Sustainability finds that utility-scale solar power and wind power generally provide greater climate and public health benefits per dollar than direct air capture (DAC), based on modelling across 22 U.S. grid regions through 2050. The authors conclude that DAC becomes competitive mainly under a breakthrough scenario in which energy use falls from 5,500 to 800 kWh and cost from US$1,000 to US$100 per tonne of CO2 captured.[90][91]
    • A meta-analysis of over 20,000 participants concludes that drugs targeting amyloid beta peptides do not meaningfully slow progression of Alzheimer's disease.[92]
  • 6 May – A study in npj Space Exploration, using radar data from India's Chandrayaan-2 orbiter, reports strong evidence for subsurface water ice in four doubly-shadowed craters near the lunar south pole.[93][94]
  • 8 May – A study published in Aging Cell reports that the exceptional-longevity-associated APOE ε2 allele is associated with enhanced DNA-damage response and repair pathways in human neurons. Using stem-cell-derived GABAergic and glutamatergic neurons, as well as human APOE knock-in mice, researchers find that APOE2 neurons show lower DNA damage and greater resistance to genotoxic-stress-induced cellular senescence than APOE4 neurons, suggesting a possible mechanism for APOE2's association with reduced Alzheimer's disease risk.[95][96]
  • 11 May – A preprint reports the discovery of Ross 318 b, a candidate temperate super-Earth orbiting within the habitable zone of the nearby red dwarf Ross 318. Detected using radial velocity measurements from CARMENES and HIRES, the planet has a 39.6-day orbit, a minimum mass of 6.21 Earth masses, and shows no detectable transit in TESS photometry.[97]
  • 12 May – A study published in Frontiers in Earth Science reports isotopic evidence from helium and carbon in hydrothermal fluids from Zambia's Kafue Rift, suggesting early-stage rifting in the proposed Southwestern Rift of Africa. The findings indicate mantle-derived fluids reaching the surface and may support the existence of an emerging plate boundary capable of future continental separation.[98][99]
  • 26 May – A preprint reports the atomically precise mechanosynthesis of carbon structures on hydrogenated silicon using inverted-mode scanning tunneling microscopy (STM). Researchers demonstrate controlled donation of C2 units to pre-patterned reactive sites, repeated placement of carbon units, and stepwise formation of polyyne-like carbon chains through successive C–C bond formation, suggesting a possible route toward programmable atomically precise fabrication.[100]
  • 27 May – A study published in Light: Science & Applications describes an additive-free, brine-discharge-free solar-thermal desalination method that uses femtosecond laser-etched superwicking black metal to produce fresh water from real ocean water while collecting nearly all remaining salts as solids. Tests using samples from the Pacific, Atlantic, and Indian Oceans show that the self-cleaning surface can prevent salt and mineral build-up, a major limitation of existing solar desalination systems.[101][102]
  • 31 May – A Phase 3 trial published in the New England Journal of Medicine reports that daraxonrasib, an investigational oral RAS(ON) inhibitor, nearly doubles median overall survival in patients with previously treated metastatic pancreatic cancer, from 6.6 months with standard chemotherapy to 13.2 months.[103][104]

June

  • 1 June – A bioRxiv preprint reports the first use of base editing to alter the genome of early human embryos. Researchers at Columbia University used the technique to introduce precise single-letter DNA changes without the large chromosomal alterations previously associated with double-strand-break CRISPR gene editing, while noting that the approach remains far from clinical use and raises ethical questions over human germline engineering.[105][106][107]
  • 3 June – A report by the United Nations University Institute for Water, Environment and Health estimates that global data centre electricity consumption could reach 945 TWh by 2030, driven partly by growing demand for artificial intelligence, with associated water use rising to 9.3 trillion litres and carbon dioxide emissions to 399 million tonnes.[108][109]
  • 4 June – Chinese researchers discover the two-state model of liquid water theorizing that water is composed of two distinct and interconvertible local structures at the high and low density phase boundary.[110]
  • 5 June – Researchers at the University of Cambridge and DIOSynVax report the first human clinical trial of a vaccine whose active component was designed entirely by computer simulations. The candidate pan-Sarbecovirus vaccine, pEVAC-PS, uses a machine-learning-designed "super-antigen"; a phase I trial in 39 healthy volunteers finds it safe and able to trigger immune responses to SARS-CoV-2, SARS-CoV-1, and related bat coronaviruses.[111][112]
  • 9 June – A study in the Journal of Peace Research, using data from the Uppsala Conflict Data Program, reports that 2025 saw a record 65 state-based armed conflicts and eight interstate conflicts, the highest number of interstate conflicts since data collection began in 1946. The study also estimates that 244,600 people were killed in organised violence during 2025, driven partly by a sharp rise in one-sided violence against civilians in Sudan.[113][114]
  • 11 June – The National Oceanic and Atmospheric Administration declares the onset of an El Niño event in the tropical Pacific, and forecasts a 63% chance that it will rank among the largest since records began in 1950.[115]
  • 18 June – A study published in The Lancet, led by Queen Mary University of London and funded by Cancer Research UK, estimates that the HPV vaccine has prevented around 200 deaths from cervical cancer in England, and finds that no women aged 20–24 died from the disease between 2020 and 2024, the first such period on record.[116]
  • 19 June – A study published in Science Advances finds that high-end but physically plausible meltwater from the Greenland ice sheet could significantly worsen the long-term weakening of the Atlantic meridional overturning circulation (AMOC), especially after 2100, but does not make projected AMOC changes abrupt or irreversible on centennial timescales in the model used. In a carbon dioxide reversal experiment beginning in 2250, AMOC strength recovers after carbon dioxide concentrations return to 2015 levels by around the year 2420.[117]
  • 25 June – Astronomers report the discovery and confirmation of two unusually low-density exoplanets, TOI-791 b and TOI-791 c, orbiting the star TOI-791 about 1,113 light-years from Earth. Detected using NASA's Transiting Exoplanet Survey Satellite, the Jupiter-sized "super-puff" planets have densities of 0.038 and 0.047 g/cm3, respectively, making them among the lowest-density giant planets known and the largest planets yet found with densities below 0.05 g/cm3.[118][119]
  • 29 June – Palaeontologists identify a fossil vertebra collected on James Ross Island in 1985 as the earliest-known dinosaur bone collected in Antarctica. The specimen, stored for 40 years in the British Antarctic Survey collections, is confirmed to be a tail bone from a titanosaur, a group of long-necked sauropod dinosaurs. The animal is estimated to have lived about 82 million years ago, during the Late Cretaceous, when Antarctica was covered in forest.[120]
  • 30 June – Astronomers report a revised orbit and mass for the nearby habitable zone super-Earth GJ 3378 b. Combining radial velocity data from the Habitable-zone Planet Finder, NEID, CARMENES and SPIRou spectrometers, the team finds that the planet has an orbital period of 21.45 days and a minimum mass of 2.3 Earth masses, rather than earlier estimates of 24.73 days and 5.26 Earth masses. The revision leaves the planet within the conservative liquid-water habitable zone of its red dwarf host star, increases the likelihood that it has a terrestrial composition, and suggests that it may have retained an atmosphere despite high X-ray and ultraviolet exposure.[121]
