Researchers have developed the world's most accurate atomic clock, an advance reported by Phys.org. The new clock pushes precision beyond previous devices, improving timekeeping so finely that it could lose essentially no time over the age of the universe. Such clocks underpin GPS, telecommunications and fundamental physics tests, including measuring gravity's effect on time and searching for dark matter.
- 2Why AI struggles to forecast hurricane intensity▼Why AI has trouble predicting the fury of hurricane intensity
AI-based forecasting has improved hurricane track predictions, but rapid intensification remains difficult to model. Phys.org reports that machine learning systems have trouble capturing the small-scale ocean and atmosphere processes that drive a storm's sudden surge in strength, which is often the most dangerous element for coastal communities. Forecasters say intensity errors can leave residents with little time to prepare.
- 3Bacteria on coral reef fish gills carry chemosynthesis genes, DNA study finds●DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills
Scientists have found that bacteria living on the gills of coral reef fish carry genes for chemosynthesis, the process of making food from chemicals rather than sunlight. The discovery, reported by Phys.org, suggests gill-dwelling microbes may play a previously overlooked role in reef nutrient cycles and could reshape how researchers understand symbiosis on coral reefs.
- 4New method developed to decode insect sexual communication▼Crop protection: A new method for understanding insect sexual communication
Researchers have introduced a new method for understanding how insects communicate sexually, according to a report carried by Phys.org. The work, framed under crop protection, could help in developing ways to disrupt pest mating and reduce insecticide use. Further details on the research team, funding and practical applications were not provided in the available coverage.
