LHC: Five new particles hold clues to sub-atomic glue

LHC: Five new particles hold clues to sub-atomic glue

Image copyright EQUINOX GRAPHICS/SCIENCE PHOTO LIBRARY The Large Hadron Collider has discovered new sub-atomic particles that could help to explain how the centres of atoms are held together. The particles are all different forms of the so-called Omega-c baryon, whose existence was confirmed in 1994. Physicists had always believed the various types existed but had […]

Scientists play ‘geological genealogy’

Image copyright Rick Carlson Image caption The rocks on the eastern shores of the Hudson Bay are among the oldest on Earth Scientists have tracked the “family history” of a rock back to some of the earliest times on Earth. Researchers analysed the concentration and distribution of particular types of atoms in the granite to […]

Climate change: Biofuels ‘could limit jet contrails’

Image copyright NASA Image caption The aim was to sample emissions under real-world conditions Some close-quarter flying has provided new insights into aircraft pollution. US space agency-led scientists flew small, instrumented, chase planes directly in the exhaust plume of a big jet to measure the sorts of gases and particles being thrown out. The data […]
