• A 'remelting' of lunar surface adds a wrinkle to mystery of Moon's true age December 18, 2024
  Scientists propose a 'remelting' of the Moon's surface 4.35 billion years ago due to the tidal pull of Earth causing widespread geological upheaval and intense heating.
• Thorium film could replace crystals in atomic clocks of the near future December 18, 2024
  Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even rewrite some of the fundamental laws of physics. Thorium-229-doped crystals are both scarce and radioactive. A thin film using a dry precursor of […]
• How to print a car: High-performance multi-material 3D printing techniques December 18, 2024
  A future where lightweight car parts can be made with a 3D printer is here, thanks to multi-material additive manufacturing research.
• Prehistoric rock in Japan reveals clues to major ocean anoxic event December 17, 2024
  Researchers analyzed radioisotopes in layers of fossilized volcanic ash. Decay of uranium to lead within tiny crystals enabled scientists to precisely pinpoint dates for certain events. They determined this event occurred 119.5 million years ago -- coincident with evidence for massive volcanic eruptions -- and lasted for 1.1 million years. Study results help scientists better […]
• Physicists 'bootstrap' validity of string theory December 17, 2024
  String theory remains elusive as a 'provable' phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical method that points to its 'inevitability.'
