New genus, species of sponge in Pacific
A new genus and species of sponge has been discovered living on nodules of rock in the Pacific Ocean that are targets for mining. Plenaster craigi was found in the Clarion-Clipperton Zone between Mexico and Hawaii.
Strontium atoms, laser beams used to create precise atomic clock
The most precise atomic clock to date has been created. The quantum gas clock was made using chilled strontium atoms and laser beams.
Proton radius measured at smaller size
Protons have been measured at a smaller size by scientists at Germany’s Max Planck Institute of Quantum Optics. The new proton radius measurement is 0.83 femtometers, compared with the textbook measurement of 0.88 femtometers.
Nocebo effect of expensive-looking medications
Patients may experience stronger side effects if they believe a medication is more expensive, according to a study of the nocebo effect, the opposite of the placebo effect.
