For 5 million years, whales have come to this place in the Indian Ocean to die

For 5 million years, whales have come to this place in the Indian Ocean to die Graveyard discovered by Chinese team is Earth’s deepest and most extensive for whale fossils, carcasses and the ecosystems they support The graveyard is the Earth’s deepest and most extensive known accumulation of whale fossils, carcasses and the unique ecosystems they support, with some fossils dating back about 5.3 million years. Detailed in a paper published in the peer-reviewed journal Nature on Wednesday, the...

How a decade-long bet on photonics handed this Chinese venture capital firm an AI windfall

ExclusiveHow a decade-long bet on photonics handed this Chinese venture capital firm an AI windfall For Mi Lei, founder of venture capital firm CAS Star, the sudden fascination with photonics is less a surprise than a delayed validation As artificial intelligence strains the physical limits of existing data centres, scientists and investors are turning to the ultimate speed limit of the universe for the next computing frontier: light. For Mi Lei, founder of CAS Star, a venture capital firm...

Top Chinese map-making scientist detained in anti-corruption sweep

Top Chinese map-making scientist detained in anti-corruption sweep Zhou Chenghu, a cartographer with a business empire in geographic information and low-altitude economy, probed by anti-graft authorities In late May, the Economic Observer, a weekly Chinese newspaper, cited “informed sources” and said the 62-year-old CAS academician had been taken away by disciplinary inspectors from the lobby of his research institute building in late April. His personal details have since been removed from...

Future jet stream changes could ease drying across Asian drylands

Future jet stream changes could ease drying across Asian drylands Lisa Lock Scientific Editor Robert Egan Associate Editor Mid-latitude Asian drylands, stretching from Central Asia to northern China, are among the largest dryland systems in the world. Home to extensive agricultural activities and fragile ecosystems, the region is highly vulnerable to climate change and water scarcity. A thermodynamic perspective suggests that global warming will intensify dryness in arid regions, following...

RNA-guided transposon mechanics show use of figure-eight intermediate and direct-transfer route

RNA-guided transposon mechanics show use of figure-eight intermediate and direct-transfer route Gaby Clark Scientific Editor Robert Egan Associate Editor IS110 transposons are a large, diverse family of bacterial insertion sequences (IS elements)—small, mobile DNA elements that can move from one genomic location to another. They have recently attracted broad interest due to the finding that some of these transposons use a bridge RNA (bRNA) to recognize both donor DNA and target DNA. Upon...

SIRT7 regulates dosage compensation and safeguards the female X chromosome

Abstract Sirtuins are deacetylases implicated in stress responses and longevity in mammals1,2. Although their differential impact on disease for the two sexes has been noted3,4,5,6,7, the underlying reasons are unclear. Here, using Sirt7 as a model in mice, we examine the mechanisms leading to sex differences and find that Sirt7−/− female mice have decreased fitness throughout their lifespan.

A thalamus–brainstem attractor network drives history-biased decisions

Abstract Natural environments often change gradually, making it adaptive to bias decisions on the basis of the recent past — a phenomenon known as serial dependence1,2,3. Large-scale recordings during behaviour have identified that serial dependence is a common motif for decision-making, with neural representations of past experiences found throughout the brain4,5,6,7,8,9,10,11. However, it remains unclear whether this bias arises from dedicated neural circuits with history-specific...

A 5.3-million-year-old deep-sea whale necropolis in the Diamantina Zone

Abstract Whale falls are biodiversity oases at seabeds1,2,3,4,5,6, yet their record from the oceans has remained sparse and fragmentary6,7. Here we report the discovery of a vast whale necropolis in the Diamantina Zone (4,616- to 7,001-m depth), extending about 1,200 km along the sea floor of the southeastern Indian Ocean. This area has a deep and extensive accumulation comprising five modern natural whale-fall communities and 476 fossil cetaceans recorded.
