Photographs can reveal things that are otherwise impossible for the naked eye to see, be they distant galaxies or microscopic cells. Researchers at Osaka Metropolitan University have developed a practical and versatile imaging ...
Phys.org / Molecular clock transitions tune out the noise in the hunt for new physics
Heavy polar molecules are some of the most sensitive tools physicists have for probing what lies beyond the Standard Model, the theory that describes the particles and forces we know about. But turning that sensitivity into ...
Phys.org / JWST captures rare glimpse of early black hole growing inside network of young galaxies
Astronomers using the James Webb Space Telescope have captured one of the clearest views yet of how an early supermassive black hole may grow within a network of young galaxies. The compact active galaxy, seen just a billion ...
Phys.org / Physicists turn to the universe's 'piano notes' to detect hidden particles
It's been said that a finely tuned ear knows the size and shape of a piano by merely listening to the instrument's notes. An international team of physicists has now devised an analogous approach to detect the universe's ...
Phys.org / Fossilized wood reveals 300 million years of Earth's history
Many people are familiar with fossilized wood as a decorative item from a museum shop. However, the fact that it can preserve the geological history of entire regions spanning millions of years is a new discovery. A research ...
