The natural world in science and life
The Jiangmen Underground Neutrino Observatory has started collecting data, producing some of the most precise measurements yet of how neutrinos switch flavors. Initial results test the detector’s capabilities and set the stage for cross-checks with Hyper-Kamiokande and DUNE.
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.
