(Phys.org) -- The OPERA collaboration has announced yesterday at the Neutrino 2012 conference in Japan, the observation of their second neutrino tau interaction, after the first observation made in 2010.

(PhysOrg.com) -- Scientists at the Joint Quantum Institute (JQI) have for the first time engineered and detected the presence of high angular momentum collisions between atoms at temperatures close to absolute zero. Previous experiments with ultracold atoms featured essentially head-on collisions. The JQI experiment, by contrast, is able to create more complicated collisions between atoms using only lasers

Plasma etching (using an ionized gas to carve tiny components on silicon wafers) has long enabled the perpetuation of Moore's Law -- the observation that the number of transistors that can be squeezed into an integrated circuit doubles about every two years. Without the compensating capabilities of plasma etching, Moore's Law would have faltered around 1980 with transistor sizes at about 1 micron (the diameter of a human hair is approximately 40-50 microns wide). Today, etch compensation helps create devices that are smaller than 20 nanometers (1,000 times smaller than a micron).

(PhysOrg.com) -- By precisely shaking a container of shallow water, researchers have observed wave behavior that has never been seen before. In a new study, Jean Rajchenbach, Alphonse Leroux, and Didier Clamond of the University of Nice-Sophia Antipolis in Nice, France, have reported the observation of two new types of standing waves in water, one of which has never been observed before in any media.

(PhysOrg.com) -- In April, scientists at one of Fermilab’s two particle detectors, CDF, observed what they thought might be a new particle not predicted by the Standard Model. But now, scientists at the lab’s second detector, DZero, have cross-checked the observation with their own independent data and analysis tools, and have found no evidence of a new particle. Instead, the DZero data are in agreement with predictions from the Standard Model.
