Never thought we’d ever utter these words, but… can anyone recommend a spin doctor for NASA? • The Register

Bennu, the asteroid targeted by NASA for its OSIRIS-Rex mission, is running at an increasing rate and scientists are not entirely sure why. The asteroid, shaped like a table spinner, rotates faster and faster, taking a second less to rotate for a hundred years. It may not sound like much, but given enough time, the entire asteroid could break off, …

A Radical Discovery About Waterfalls Could Rewrite The History of Earth’s Landscapes

Waterfalls are one of the most majestic things on the planet: a beautiful, thunderous display of water and physics. But where do these waterfall creations come from? According to conventional wisdom, waterfalls are formed by external forces, such as earthquakes, landslides or sea level changes that greatly alter and interrupt landscapes and river beds. But it turns out that another …

NASA’s Super-Sized Space Launch System Might Be Doomed

Testing the symmetry of space-time by means of atomic clocks

A tunable laser excites an extremely narrow-band resonance in a Yb + ion of an atomic clock. The electronic wave function of the excited state of the ion is marked in yellow. Two ions with right-angled wave functions are interrogated by laser light with an adjustable frequency shift to measure a possible frequency difference. The entire experimental setup rotates with …

Zombified mammoth cells could mean a real Jurassic Park in the future Zombified mammoth cells could mean real Jurassic Park in the future

Know the story. Guy extracts dinosaur DNA from fossilized mosquitoes. The dinosaur eggs hatch. The prehistoric theme park emerges and becomes an enormous responsibility. Dinosaurs still live. Although it may not happen again, it is still strange how scientists have now managed to reactivate cells from a woolly mammoth that died over 28,000 years ago. Just as the dino DNA …
