The massive buried structures at Gunung Padang in Indonesia would be much older than Egypt’s great pyramids — if they’re even human constructions at all.
Ancient humans painted scenes in Indonesian caves more than 45,000 years ago, but their art is disappearing rapidly. Researchers are trying to discover what’s causing the damage and how to stop it — before the murals are gone forever.
Wall Street Journal (December 6, 2023) – To help counter China, the U.S. military is racing to develop a fleet of next-generation drones. For the Pentagon, it’s not just a matter of gaining the technological edge.

It’s a race against the clock, as Beijing has militarized islands in the South China Sea, and President Xi Jinping has ordered his military to be ready to invade Taiwan by 2027. Some experts are skeptical the U.S. military can work fast enough to meet its goals.

One afternoon in early 1994 a couple of astronomers sitting in an air-conditioned computer room at an observatory headquarters in the coastal town of La Serena, Chile, got to talking. Nicholas Suntzeff, an associate astronomer at the Cerro Tololo Inter-American Observatory, and Brian Schmidt, who had recently completed his doctoral thesis at the Center for Astrophysics | Harvard & Smithsonian, were specialists in supernovae—exploding stars. Suntzeff and Schmidt decided that the time had finally come to use their expertise to tackle one of the fundamental questions in cosmology: What is the fate of the universe?
The point of the thing was to forever change our concept of power. When the U.S. military assembled a team of scientists, led by physicist J. Robert Oppenheimer, to build a nuclear bomb during World War II with the hope of beating the Nazis to such a terrible creation, many of those involved saw their efforts as a strange kind of civic destiny. The Manhattan Project, wrote Richard Rhodes, Pulitzer-winning author of The Making of the Atomic Bomb, was “compelled from the beginning not by malice or hatred but by hope for a better world.” Oppenheimer himself once said, “The atomic bomb was the turn of the screw. It made the prospect of future war unendurable. It has led us up those last few steps to the mountain pass; and beyond there is a different country.”
At 60 years old, Doctor Who, the BBC show following the adventures of the regenerating Time Lord, continues to be highly enjoyable fiction. But it’s science fiction. The Gallifreyan takes science seriously… so we take a closer look at some of the science of Doctor Who, from time travel and the TARDIS to invading Cybermen and rogue planets.
How to make the Moon on Earth
The expense and prestige involved in sending landers and rovers to the Moon means you can’t afford for them not to work when they get there. But the lunar landscape is like nothing here on Earth. So how, and where do you test equipment that’s bound for the Moon?
