Even the oldest eukaryote fossils show dazzling diversity and complexity

Santa Barbara CA (SPX) Jan 12, 2024
The sun has just set on a quiet mudflat in Australia's Northern Territory; it'll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning light. No leaves rustle in the breeze. No lichens encrust the exposed rock. The only hint of life is some scum in a few puddles and ponds. And among it lives a diverse microbial community of our ancient ancestors. In a new account of exquisitely preserved microfossils, researchers at UC Santa Barbara an ... read more

Iron in ancient deep magma ocean probed by ultra-fast femtosecond X-ray lasers

Tempe AZ (SPX) Oct 23, 2023
When the Earth was completing its formation approximately 4.5 billion years ago, it was enveloped in a global ocean of molten magma, extending hundreds to thousands of kilometers beneath its surface due to violent impacts. This early environment bore little resemblance to the habitable conditions we experience on Earth today. Nonetheless, these initial few hundred million years were crucial in shaping our planet's fundamental chemical and physical structures as we know them today. Key developments durin ... read more
