• 'Dolomite Problem': 200-year-old geology mystery resolved November 23, 2023
  For 200 years, scientists have failed to grow a common mineral in the laboratory under the conditions believed to have formed it naturally. Now, researchers have finally pulled it off, thanks to a new theory developed from atomic simulations. Their success resolves a long-standing geology mystery called the 'Dolomite Problem.' Dolomite -- a key mineral […]
• 'Strange metal' is strangely quiet in noise experiment November 23, 2023
  Experiments have provided the first direct evidence that electricity seems to flow through 'strange metals' in an unusual liquid-like form.
• Particulate pollution from coal associated with double the risk of mortality than PM2.5 from other sources November 23, 2023
  Exposure to fine particulate air pollutants from coal-fired power plants (coal PM2.5) is associated with a risk of mortality more than double that of exposure to PM2.5 from other sources, according to a new study. Examining Medicare and emissions data in the U.S. from 1999 to 2020, the researchers also found that 460,000 deaths were […]
• Telescope Array detects second highest-energy cosmic ray ever November 23, 2023
  In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power to produce it, and the particle had more energy than was theoretically possible for cosmic rays traveling to Earth from other galaxies. Simply put, the particle […]
• Hybrid transistors set stage for integration of biology and microelectronics November 23, 2023
  Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
