An iron ring set in the stone pillar of a 15th-century chapel in the Scottish city of Aberdeen may not look like much, but historians say it could be a direct link to a dark chapter in the city’s past — the trial and execution of 23 women and one man accused of witchcraft during Aberdeen's "Great Witch Hunt" in 1597.
"I was skeptical, to be honest — the ring is not all that spectacular, but it is actually quite genuine,"

28 'cocooned' black holes found hiding in plain sight
More than two dozen missing "cocooned" black holes have been rediscovered, after researchers took a new look at X-ray maps of the sky. All of these singularities had been misclassified as distant galaxies or other types of black holes.
All 28 of the objects are supermassive black holes, billions of times the mass of our sun. And all are going through a stage of development where they shroud themselves in a dark bubble of dust and other material.

Beer & Bullets to Go: Ancient 'Takeout' Window Discovered
Some 5,200 years ago, in the mountains of western Iran, people may have used takeout windows to get food and weapons, newly presented research suggests.

Did a Volcano Defeat Napoleon at Waterloo?
Napoleon's historic defeat at Waterloo may have been spurred by a volcano that erupted two months earlier, and nearly 8,000 miles (13,000 kilometers) away.
During the decisive battle on June 18, 1815, in what is now Belgium, mucky, wet conditions mired Napoleon's armies and lent a strategic advantage to his foes. But the heavy rainfall that flooded Europe during May and June that year may have resulted from a significant atmospheric disturbance in April, when an Indonesian volcano named Mount Tambora erupted, according to a new study.

Extreme, Hydrogen-Crushing Physicists Are Pushing Us into a 'New Era of Superconductivity'
"We believe this is now a new era of superconductivity," Russell Hemley, a materials scientist at George Washington University in Washington, D.C., told a crowd of researchers March 4 at the American Physical Society's March meeting.
Images lit up the screen behind him: a schematic of a device for crushing tiny things between the superhard points of opposing diamonds, graphs of temperature and electrical resistance, a glowing ball with a rough, black "

How Hawaii's Kilauea Volcano Works (Infographic)
One of the world's most active volcanoes, Kilauea is a shield-type volcano on the Big Island of Hawaii. Kilauea has been erupting continuously since 1983.
Kilauea rises to 4,190 feet (1,227 meters) above sea level. The summit caldera contains a lava lake called Halema'uma'u, said in legend to be the home of the volcano goddess Pele.
After five years of close study, scientists think the lava lake in Halema'uma'u crater is like no other place on Earth.
