![]() | Second thoughts: Is a tiny addition in time too much?Question: When is a minute not a minute? |
![]() | Researchers propose potential new way to maintain communication with hypersonic vehicles in flightNear the end of the movie Apollo 13, which depicts the harrowing journey of the three astronauts aboard the aborted 1970 lunar mission, the tension mounts in textbook fashion. As the spacecraft hurdles into Earth's atmosphere it is encircled by hot ionized air that cuts off communications with NASA Mission Control in Houston. Each second that the flight controllers' calls for contact remain unanswered is torturously stretched. |
![]() | Luminescent signals from green glowing diamond defects could monitor temperature with unprecedented versatilityResearchers have developed tiny, diamond-based probes that optically transmit detailed temperature information and can operate in conditions ranging from 150 to 850 degrees Kelvin, representing near-cryogenic cold to slightly below the melting point of aluminum. |
![]() | 3D potential through laser annihilationWhether in the pages of H.G. Wells, the serial adventures of Flash Gordon, or that epic science fiction saga that is Star Wars, the appearance of laser beams—or rays or phasers or blasters—ultimately meant the imminent disintegration of our hero or perhaps something a little larger, say, an entire planet. |
![]() | A new and game-changing magnetoresistanceMore than 150 years ago, William Thomson, later Lord Kelvin, discovered the magnetoresistive effect. Today, this finding enables sensors to measure the rotational speed of a car wheel, and is also used in compass navigation and robot control systems. ETH material scientists have now found a new kind of magnetoresistance that promises further insight into basic research and could one day be used for practical applications. |
![]() | Theory turns to reality for nonlinear optical metamaterialsA research team has realized one of the long-standing theoretical predictions in nonlinear optical metamaterials: creation of a nonlinear material that has opposite refractive indices at the fundamental and harmonic frequencies of light. Such a material, which doesn't exist naturally, had been predicted for nearly a decade. |
![]() | OPERA detects its fifth tau neutrinoThe OPERA (Oscillation Project with Emulsion-tRacking Apparatus) experiment at the Italian National Institute for Nuclear Physics (INFN) at Gran Sasso in Italy has detected the fifth occurrence of a tau neutrino in the muon-neutrino beam from CERN. A particle that left CERN as a muon neutrino underwent "oscillation" during its 730-kilometre journey to Gran Sasso, arriving as a tau neutrino. |
![]() | A novel source of X-rays for imaging purposesPhysicists at LMU Munich and the Max Planck Institute of Quantum Optics have validated a novel laser-driven means of generating bright and highly energetic X-ray beams. The method opens up new ways of imaging the fine structure of matter. |
![]() | Einstein saves the quantum catEinstein's theory of time and space will celebrate its 100th anniversary this year. Even today it captures the imagination of scientists. In an international collaboration, researchers from the universities of Vienna, Harvard and Queensland have now discovered that this world-famous theory can explain yet another puzzling phenomenon: the transition from quantum behavior to our classical, everyday world. Their results are published in the journal Nature Physics. |
![]() | Getting the measure of matterPeter Rohde and his collaborators develop big ideas – and a measure of corny humour – using photons, the smallest possible units of light. (Did you hear about the photon that walked into a hotel and the clerk asked for its luggage? The photon said, "I'm travelling light.") |
![]() | Miniscule mirrored cavities connect quantum memoriesTiny, nanoscale mirrors were constructed to trap light around atoms inside of diamond crystals, acting like a series of funhouse mirrors. The mirrored cavities in the crystal allow light to bounce back and forth up to 10,000 times, enhancing the normally weak interaction between light and the electronic spin states in the atoms. As a result, a 200-microsecond spin-coherence time – how long the memory encoded in the electron spin state lasts – was produced. |
![]() | How DNA protects itself from UV lightX-rays from the Linac Coherent Light Source were used to measure the ultrafast response of DNA nucleobases to ultraviolet light. Researchers found that the UV excited state in the nucleobase thymine decays rapidly, harmlessly dissipating the potentially destructive UV energy. |
![]() | New measurement of the mass of a strange atomic nucleus achieves very high precisionAn international team of physicists working at the Institute of Nuclear Physics at Johannes Gutenberg University Mainz (JGU) in Germany has measured the mass of a 'strange' atomic nucleus with the aid of an innovative technique that is capable of significantly greater precision than that of previous methods. The researchers were able, for the first time worldwide, to observe the radioactive decay of artificially generated nuclei of super-heavy hydrogen at the Mainz MAMI particle accelerator using a combination of several magnetic spectrometers. They could then precisely determine the mass on the basis of accurate measurement of the decay product. The results have been published in the journal Physical Review Letters. |
![]() | New beamline provides more opportunities for particle detector R&DSince 2005, DOE's Fermilab's Test Beam Facility, with its distinctive orange and blue corrugated-steel roof, has staged more than 50 experiments, conducted by scientists from more than 170 institutions in 30 countries. |
![]() | Reactor brought to first criticality after 14-month overhaulAn important research tool at DOE's Idaho National Laboratory was restarted recently after completion of a nearly 14-month overhaul-and-upgrade project. The Neutron Radiography (NRAD) Reactor provides researchers with a critical non-destructive tool for conducting post-irradiation examination of nuclear fuel and material samples. |

This is especially important when that chemical is radioactive. |
![]() | Researchers find a way to identify key nodes in illegal wildlife trade network(Phys.org)—A team of researchers with affiliations to several institutions in the U.S. has found a new way to track import, export and connecting countries in the illegal wildlife trade network. As they describe in their paper published in Proceedings of the National Academy of Sciences, their work may help identify ways to reduce such trade in order to help protect the animals involved. |
![]() | Team finds 'unprecedented' earthquake evidence in Africa 25,000 years agoLead researcher Hannah Hilbert-Wolf and supervisor Dr. Eric Roberts used innovative methods to examine the ground around Mbeya in Tanzania where a large earthquake occurred some 25,000 years ago. |
![]() | Earth's core contains 90 percent of Earth's sulfur, new research showsSo perhaps there is some truth in the old legends of the underworld reeking of brimstone (or sulphur, as it is now called)? New research confirms that the Earth's core does in fact contain vast amounts of sulphur, estimated to be up to 8.5 x 1018 tonnes. This is about 10 times the amount of sulphur in the rest of the Earth, based on the most recent estimates (and for comparison, around 10% of the total mass of the Moon). This is the first time that scientists have conclusive geochemical evidence for sulphur in the Earth's core, lending weight to the theory that the Moon was formed by a planet-sized body colliding with the Earth. This work is reported in the peer-reviewed journal, Geochemical Perspectives Letters. |
![]() | India, China need cleaner air just to keep death rate steadyNever mind lowering the rate of death from air pollution in India and China. Just keeping those rates steady will demand urgent action to clear the skies, according to a report published Tuesday. |

Hanauer and colleagues. | |
![]() | Predicting sediment flow in coastal vegetationSeagrass, kelp beds, mangroves, and other aquatic vegetation are often considered "ecosystem engineers" for their ability to essentially create their own habitats: Aquatic leaves and reeds slow the flow of water, encouraging sediments to settle nearby to form a foundation on which more plants can grow. |
![]() | Researcher discusses new ways to calculate ecosystem impacts on climateFor decades, scientists have relied on an established formula to measure the impact of greenhouse gas emissions on climate change. |
![]() | Toxic algal blooms behind Klamath River dams create health risks far downstreamA new study has found that toxic algal blooms in reservoirs on the Klamath River can travel more than 180 miles downriver in a few days, survive passage through hydroelectric turbines and create unsafe water conditions on lower parts of the river in northern California. |

![]() | Unravelling the mysteries of carbonic acid: Researchers peeling back the veil on a critical but short-lived moleculeBlink your eyes and it's long gone. Carbonic acid exists for only a tiny fraction of a second when carbon dioxide gas dissolves in water before changing into a mix of protons and bicarbonate anions. Despite its short life, however, carbonic acid imparts a lasting impact on Earth's atmosphere and geology, as well as on the human body. However, because of its short lifespan, the detailed chemistry of carbonic acid has long been veiled in mystery. Researchers with Berkeley Lab and the University of California (UC) Berkeley are helping to lift this veil through a series of unique experiments. In their latest study, they've shown how gaseous carbon dioxide molecules are solvated by water to initiate the proton transfer chemistry that produces carbonic acid and bicarbonate. |
