China has launched a 500-tonne production line to extract rubidium and caesium from lithium waste. A demonstration line in Jiangxi province – the world’s first with an annual capacity of 500 tonnes for continuous tower extraction and separation of low-grade rubidium and caesium – has achieved st...
Eighty years ago, a massive tsunami devastated parts of Hawaii, Alaska, Washington and Oregon following an earthquake off the coast of Alaska. A Michigan State University team is launching a project to study the underwater fault system where it originated—and whether it still poses a risk today.
Ancient DNA reveals that plague was already killing hunter-gatherers in Siberia 5,500 years ago, long before cities and flea-driven epidemics. The prehistoric strains may have been especially dangerous because they carried a genetic factor capable of provoking severe immune reactions.
More than 60 years after surveys suggested a deep coral reef off Benin was probably dead, scientists have found it alive. Cameras revealed healthy-looking coral patches supporting multiple fish species more than 50 meters beneath the surface. The discovery suggests West Africa’s coastal waters ...
When JWST's first science results started rolling in, it was a triumph for scientific vision and persistence. For years, the fate of the powerful space telescope was uncertain. It went way over budget, and for 25 years, troubling conversations accompanied its ongoing development.
Choosing an orbit for a satellite always comes with trade-offs. Very low Earth orbit (VLEO), between 100–450 km (62–280 miles), has distinct advantages. Remote-sensing cameras can take better pictures, communications and radar require less power, and atmospheric drag automatically cleans up dea...
