Astronomers have detected helium escaping from LHS 1140b, a rocky 'super-Earth' 48 light-years away that orbits in its star's habitable zone. The finding has confirmed an atmosphere around a habitable-zone rocky exoplanet for the first time and has been published in Science; teams used ground-based infrared spectroscopy and modelling.
University of Minnesota research shows driving at posted speed limits could save millions in fuel costs daily, cut emissions, and add less than a minute to commutes. The study analyzed 120 million US trips on highways 45 mph or higher, finding speeding is common but yields negligible time savings.
International researchers find inherited genetics influence how cancers evolve after DNA damage, affecting tumour growth and mutation patterns. The Edinburgh-led work, published in Nature, underlines implications for screening, diagnosis and personalised treatment across populations.
New research using canopy lasers has mapped earthworks across the Amazon, suggesting the Anquiry civilization supported 1.25 to 3 million people at its peak and built a network of geoglyphs and roads with ceremonial centers. The findings challenge the idea of an untouched rainforest and imply a long and complex precolonial society.
Scientists have captured the Sun’s surface at unprecedented resolution with the Daniel K. Inouye Solar Telescope and other instruments and have identified widespread Kelvin–Helmholtz vortices—500–2,000km spirals of magnetised plasma. The team has linked these instabilities to how magnetic energy cascades to smaller scales and feeds flares and coronal mass ejections that produce space weather.
Researchers at Stanford and the Arc Institute have used generative genome models to design and synthesise bacteriophage genomes; 16 of the lab-made viruses proved viable and a cocktail of them rapidly killed E. coli strains resistant to natural phages. Experts have warned the work has raised urgent biosafety and biosecurity questions about AI-designed genomes.
A class-action-like suit claims Oura’s sleep tracking relies on AI estimates rather than physiological signals, arguing the ring cannot accurately determine sleep stages. The case cites a Nature study showing limited accuracy, while Oura defends its methodology and insists its data are scientifically grounded.
This week has seen several medical research and regulatory developments. Insilico Medicine has reported that its experimental drug rentosertib changed blood‑protein patterns that aging clocks read as three to four years younger in a small trial. Stanford teams have published studies showing they can grow hindbrain neurons separately and implant human cortical organoids into mice. The US health department has appointed permanent directors for three FDA centers.
Biotech researchers are developing methods to alter gene expression without changing the DNA sequence, using epigenome editing to treat chronic diseases. The approach differs from traditional gene editing by targeting when and where genes are expressed in cells.
Disaster-hit Nepal faces mounting rebuilding costs after a glacier collapse triggered devastating floods. Scientists link warming to destabilisation of glaciers, while international finance bodies struggle to mobilise funds. Nepal urges faster climate finance to support relief, reconstruction and loss-and-damage claims.
Stanford researchers have transplanted human brain organoids into mice with cortex-depleted brains, creating a model that links human tissue with mouse neural circuits. The work, reported in Nature, shows human cells wiring into mouse brain tissue and drawing attention to ethical oversight and limitations in translating to human disease.
New geophysical surveys have revived the possibility that hidden corridors behind Tutankhamun’s tomb may house space connected to Queen Nefertiti’s burial complex. Researchers propose drilling a narrow borehole to test anomalies north of KV62, potentially expanding Egypt’s most famous royal necropolis.
