Feed SubscriptionThe importance of fundamental measurements
At the Radioactive Isotope Beam Facility (RIBF) of the RIKEN Nishina Center for Accelerator Science in Wako, a research team has measured the time it takes for 38 extremely rare isotopes to decay by half. This is the first study of half-lives for 18 of the isotopes. The data provide a long-awaited test of theoretical predictions of the rate at which these isotopes decay, and will help nuclear physicists to understand a fundamental source of many of the atomic elements and their isotopes

Optical data carriers such as DVDs, Blu-rays and CD-RWs store data in layers of so-called "phase change materials". In the future, these materials will enable the development of fast, non-volatile and energy-saving main memories. A prerequisite for this is a low thermal conductivity

(PhysOrg.com) -- Like a fish paddles its pectoral fins to swim through water, flying insects use the same physics laws to "paddle" through the air, say Cornell physicists.

(PhysOrg.com) -- A data memory can hardly be any smaller: researchers working with Gerhard Rempe at the Max Planck Institute of Quantum Optics in Garching have stored quantum information in a single atom. The researchers wrote the quantum state of single photons, i.e. particles of light, into a rubidium atom and read it out again after a certain storage time
