In a world obsessed with the apocalyptic hellfire of ‘carbon’ and the terror of an imperceptibly warmer climate nowhere near ...
Biomass reveals the real impact and energy flow of life in an ecosystem, like knowing not just the cast of a play, but who ...
In a first-of-its-kind study, Stanford researchers have measured how the abundance of ocean life has changed over the past half-billion years of ...
土星有环,天王星有环,木星和海王星也有自己的环。身为一颗气态巨行星,有个环在身边应该很合理吧?但是对于内太阳系的岩质行星来说,它们一没有强大的引力捕获天体,二离太阳又那么近,很容易让水冰挥发,所以内太阳系的小家伙们很难拥有自己的行星环。然而你可能不知 ...
Among them, the Late Ordovician Mass Extinction (LOME) is the earliest of the Phanerozoic, and questions about its causes and dynamics have been a central focus in Earth sciences over the past century ...
More information: Zhutong Zhang et al, Tempo of the Late Ordovician mass extinction controlled by the rate of climate change, Science Advances (2025). DOI: 10.1126/sciadv.adv6788 ...
Surprising new fossil evidence undermines the idea that there was ever a mass extinction on land – and may force us to reframe the current biodiversity crisis ...
During this period, the average species extinction rate drastically increased to 71.6% per 100 kyr. This study quantitatively demonstrates the dominant role of the rate of climate change in ...
Long before that – like, almost 400 million years before – the world was already testing out its appetite for apocalypse with a little-known event called the Late Ordovician mass extinction.
This excludes extinction events linked to other factors such as asteroid impacts or the ice ages. Comparing these data sets, the experts found that their research supported the theory that a supernova ...
Fossils of 444 million-year-old creatures whose bodies were preserved "inside-out" have been discovered in South Africa.
Without that protection, sunlight becomes toxic. UV exposure rises, ecosystems destabilize, and a cooling effect—possibly even glaciation—can follow. Scientists now believe that such an event could ...
