Nature is the leading science journal and brand covering discoveries across biology, physics, earth science, and beyond.
A Texas fossil dating to 324 million years ago reveals an insect with 24 legs, challenging long-held views on early arthropod evolution. Researchers say this pushes back the hexapod gap and suggests insects had complex origins beyond today’s limb count.
Princes has shifted its canned mackerel to Chilean jack mackerel, a different species, amid overfishing concerns and sustainable sourcing. Lidl and other retailers are following. Critics say the move affects nutrition and taste, while authorities have relaxed labeling rules. The debate centers on skimpflation, sustainability, and consumer transparency.
Researchers reveal a vast whale graveyard in the southeastern Indian Ocean, extending to depths of 7,000 metres and spanning hundreds of kilometres. The site hosts hundreds of fossil skeletons and five modern whale falls, highlighting a thriving deep-sea ecosystem that feeds on whale carcasses. The findings, published in Nature, deepen understanding of deep-sea life and whale evolution.
Scientists have analysed teeth from hunter-gatherers around Lake Baikal and found plague DNA in 18 individuals, showing two distinct outbreaks about 5,500 years ago and earlier emergence of Yersinia pestis at least 5,700 years ago. The findings challenge the idea that plague began with farming.
UC San Diego researchers have demonstrated teleoperated humanoid robots performing gallbladder removals on live animals, marking a potential step toward remote surgery. Two procedures were conducted; one with a human surgeon guiding a single robot, the other with two robots collaborating. The work, published in Nature, shows cost and space advantages over traditional surgical robots but highlights calibration and latency challenges.
Sotheby’s has sold a 67‑million‑year‑old Tyrannosaurus rex skeleton nicknamed “Gus” for $50.1 million, the highest price ever paid for a dinosaur at auction. The specimen, about 61–63% complete, was excavated in South Dakota from 2021–23; scientists are warning that private ownership will restrict research access.
NatureScot plans an online register for Scotland’s ancient woodlands, recording location and conditioning. The system, due to live in 2027, will include conifer forests, recently planted woodlands and even ‘ghost’ woods, with a PIN procurement launching 2026–27.
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.
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.
