New Study Highlights Ancient Technology's Role in Future Clean Energy

Energy-daily.com 

Los Angeles CA (SPX) Aug 05, 2024 - A Bronze Age technology may provide a quick and cost-effective method to meet the United Nations' climate goal of net zero emissions by 2050, according to recent Stanford-led research published in PNAS Nexus.

The technique involves using heat-absorbing bricks, known as "firebricks," stored in an insulated container to capture heat generated by solar or wind power. This heat can be later released by passing air through channels in the brick stacks, enabling factories for cement... Читать дальше...

Ancient Stars Found in Milky Way's Thin Disk

Spacedaily.com 

Berlin, Germany (SPX) Aug 05, 2024 - A recent study leveraging machine learning and data from the Gaia mission has unveiled a significant finding about the Milky Way's evolution. Researchers discovered a large number of ancient stars on orbits similar to our Sun within the galaxy's thin disk. These stars, forming less than a billion years after the Big Bang, suggest the thin disk's formation occurred several billion years earlier than previously thought.

The Milky Way consists of a halo, a central bulge and bar... Читать дальше...
