Researchers at the Niels Bohr Institute have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks. The new measurements show a lifetime of 2050 seconds, which corresponds to approximately

(PhysOrg.com) -- The physicists of the University of Innsbruck and the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck have come considerably closer to their goal to investigate complex phenomena in a model system: They have realized a digital, and therefore, universal quantum simulator in their laboratory, which can, in principle, simulate any physical system efficiently. Their work has been published in the online issue of the journal Science.

Complete Genomics is taking a look at the genomes of 1,000 children to get a better picture of how to understand and treat pediatric cancer. Ever since we sequenced the first human genome, projects that involve delving into genes have exploded--scientists even recently just sequenced marijuana's genome . Now, a new project aims to look at some slightly younger genes

Physicists with the Institute of Ultrafast Spectroscopy and Lasers (IUSL) at The City College of New York have presented a new way to map spiraling light that could help harness untapped data channels in optical fibers. Increased bandwidth would ease the burden on fiber-optic telecommunications networks taxed by an ever-growing demand for audio, video and digital media

From Nature magazine Vaccines are largely safe, and do not cause autism or diabetes, the US Institute of Medicine (IOM) said in a report issued today . This conclusion followed a review of more than 1,000 published research studies. [More]

Knots can now be tied systematically in the microscopic world. A team of scientists led by Uros Tkalec from the Jozef Stefan Institute in Ljubljana (Slovenia), who has been working at the Max Planck Institute for Dynamics and Self-Organization in Gottingen (Germany) since September 2010, has now found a way to create every imaginable knot inside a liquid crystal.

(PhysOrg.com) -- Organic light-emitting diodes (OLEDs) are seen as a promising replacement for the liquid-crystal displays (LCDs) used in many flat-screen televisions because they are cheaper to mass-produce. Zhikuan Chen at the A*STAR Institute of Materials Research and Engineering and co-workers have now shown how meticulous engineering of fluorescent molecules can dramatically increase OLED efficiency.

Ten years ago, NFL player Korey Stringer died of complications of heat stroke.

There was one recent positive survey, but test after test has found that people aren't so psyched when smart meters arrive in their home. They may not have a choice. There are actually two electrical grids being built in the U.S

For decades, policy makers have tried and failed to get Americans to eat less salt. In April 2010 the Institute of Medicine urged the U.S.

The single biggest factor, by far, in reducing the rate of death among children younger than five is greater education for women. In all countries worldwide, whether females increase schooling from 10 years to 11, say, or two years to three, infant mortality declines , according to a recent study by the Institute for Health Metrics and Evaluation at the University of Washington

For years health officials have thrown money at ways to prevent young children from dying, with little global data on effectiveness. Recently a pattern has emerged: mortality drops in proportion to the years of schooling that women attain

Kinsey Institute questionnaire given to 1,000 couples yields surprising findings on relationship and sexual satisfaction

The Inamori Foundation announced this year's Kyoto Prizes on June 24. It awarded the Basic Sciences prize to astrophysicist Rashid Sunyaev of the Max Planck Institute for Astrophysics and the Advanced Technology prize to materials scientist John W. Cahn of the U.S.

The quantum mechanical entanglement is at the heart of the famous quantum teleportation experiment and was referred to by Albert Einstein as "spooky action at a distance". A team of researchers led by Anton Zeilinger at the University of Vienna and the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences used a system which does not allow for entanglement, and still found results which cannot be interpreted classically
