First experimental signs of a New Physics beyond the Standard Model

Physicists have predicted deviations in the probability of one of the B meson decays that have been detected experimentally in the LHC accelerator at CERN. Confirmation of these results would be the first direct evidence of the existence of the 'new physics', a more fundamental theory than the current Standard Model.

Tiny, brightly shining silicon crystals could be safe for deep-tissue imaging

Tiny silicon crystals caused no health problems in monkeys three months after large doses were injected, marking a step forward in the quest to bring such materials into clinics as biomedical imaging agents, according to a new study.

Panel calls for unified proposal for ambitious X-ray laser

(Phys.org) —A panel of experts convened by the U.S. Department of Energy has suggested that the DOE fund just one laser, rather than the two that were expected to receive funds for a new type of research facility. In contention are Lawrence Berkeley National Laboratory (LBNL) and SLAC National Accelerator Laboratory in Menlo Park. Both are current DOE funded laboratories engaged in X-ray technology.

Data storage: Measuring the downside of downsizing

To keep pace with the rapidly growing consumer demand for data storage, hardware engineers are striving to cram as much electronic information into as small a space as possible. Jinmin Zhao, Mingsheng Zhang and co‐workers at the A*STAR Data Storage Institute, Singapore, have now devised a technique to assess the impact of making these devices more compact. Insights resulting from this work will guide the future design of stable disk drives.

Stabilisation of microdroplets using ink jet process

Progress means that many things that are used in everyday life are becoming more manageable, practical and generally smaller. This also applies to biological and chemical experiments. To save material and resources, scientists are trying to reduce their experiments to increasingly smaller sizes and scales. But micrometre-sized droplets evaporate very quickly, making the smooth handling of a micro experiment difficult.

NASA Invites Media to Preview Pollution-Climate Science Flights

For a behind-the-scenes look at NASA's upcoming airborne campaign to study how air pollution from wildfires and other sources affects our climate, NASA will host a media day from 8-11 a.m. CDT Wednesday, Aug. 21, in Houston.

NASA Completes First Internal Review of Concepts for Asteroid Redirect Mission

NASA has completed the first step toward a mission to find and capture a near-Earth asteroid, redirect it to a stable lunar orbit and send humans to study it.

NASA TV Coverage Set for Japanese Cargo Ship Destined for Space Station

The launch of a Japanese cargo spacecraft to the International Space Station and its arrival at the orbiting laboratory will be broadcast on NASA Television Aug. 3 and Aug. 9.

Researchers identify cause of LED 'efficiency droop'

(Phys.org) —Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called "efficiency droop" that causes LEDs to lose up to 20 percent of their efficiency as they are subjected to greater electrical currents. Efficiency droop, first reported in 1999, has been a key obstacle in the development of LED lighting for situations, like household lighting, that call for economical sources of versatile and bright light.

To infinity and beyond: Teleporting humans into space

In the science fiction show, Star Trek, teleportation is a regular and significant feature. But how much time and power is required to send the data needed to teleport a human being?
