NASA’s Jet Propulsion Laboratory recently reached a significant achievement in space travel technology. They successfully tested a lithium-fed magnetoplasmadynamic (MPD) thruster, establishing a domestic power milestone for power output in the United States with 120 kilowatts. Unlike traditional rockets, this engine uses electromagnetic fields to accelerate ionised lithium plasma, providing the necessary thrust for missions…

Six million years ago, the Mediterranean Sea evaporated, leaving behind a vast salt desert and mineral deposits.

Nonetheless, had…

Beneath the Salton Sea’s arid surface lies a vast geothermal basin holding supercritical fluid rich in lithium, dubbed “Lithium Valley.” Image Credits: via Wikimedia Commons The Salton Sea has long been considered an area of ecological strife, an evaporating salt lake located in the California desert, characterised by arid banks rather than economic prosperity. However,…

The world’s largest iceberg, A-23A, transformed from white to electric blue as it entered warmer waters, a sign of its ageing process.

For many years, the world’s largest iceberg, called A-23A, was just a giant piece of frozen…

Archaeologists have revealed that many Scottish loch islands are not natural but are ancient man-made crannogs, constructed as early as 3600 B.C.

A secret tunnel has been discovered in Bloxham village, Oxfordshire. This discovery confirms old village tales of hidden passages. The tunnel likely served as an escape route for Catholics during religious conflicts.

The extraordinary aerial photograph captured by NASA on its Earth Observatory site shows the evolution of a “sea of rotating clouds” in the region around Antarctica as a result of fierce winds, forming a phenomenon called the Von Kármán vortex streets. This astonishing image was taken by NASA using Landsat 8 over Peter I Island…

At just 17, Dasia Taylor turned a science fair idea into a medical innovation with real-world promise. While studying at Iowa City West High School in Iowa, she began working on colour-changing surgical sutures that could signal infection before a wound became visibly worse. Her inspiration came from a practical problem: expensive “smart” sutures already…
