New Desalination System Turns Seawater Into Drinking Water and Useful Salts – Including Lithium

Yesterday at 05:54 AM, via Slashdot

“Scientists have developed a solar desalination system that turns seawater into drinking water without creating environmentally damaging brine,” reports ScienceDaily. “Special laser-textured metal panels use sunlight to evaporate water while automatically moving salt deposits away from the working surface, preventing clogging. The process was successfully tested with water from three oceans and...

Something Made Earth’s Molten Core Reverse Direction In 2010

Yesterday at 04:08 AM, via Slashdot

ScienceAlert reports:In the molten ocean of iron churning in Earth’s outer core, a section deep beneath the Pacific Ocean suddenly reversed direction and started moving eastward against the planet’s usual westward flow.

US, Australia, and UK Plan New Unmanned Vehicles to Protect Undersea Data Cables

Yesterday at 03:08 AM, via Slashdot

“Around 570 cables (plus a further 80 planned) carry between 95% and 99% of the world’s intercontinental telecommunications data,” reports CNN (since fiber cables offer speeds of terabits per second, carry much more data than satellite links). And “networks of green energy cables carrying electricity are also starting to sprawl across the world’s seabeds.” Now to protect them, the U.S.,...

‘The Oral Tradition That Built Software May Not Survive AI’

Renewable Energy is Surging in Africa

Sunday at 20:34 PM, via Slashdot

Almost a fifth of the earth’s population lives in Africa. And Africa’s next generation of power projects “is increasingly being built around solar and wind power and battery storage,” reports the Associated Press, “as governments and investors shift away from coal and large hydropower dams in search of cheaper, faster and more reliable electricity.”The shift is visible in a $1.5 billion energy...

AI Agents Get Their Own Directory Built Atop DNS

Sunday at 18:34 PM, via Slashdot

“In the future, AI agents will be able to find one another using the Domain Name System (DNS), instead of crawling about and probing ports or checking configured resources,” writes The Register. InfoWorld writes that “numerous proprietary agent registries are on the market, but the Linux Foundation suggests we simply extend the distributed, open Domain Name System (DNS) infrastructure we...
