Extending Einstein's ideas: New kind of quantum entanglement demonstrated

Physicists have published new research which builds on the original ideas of Einstein and adds a new ingredient: a third entangled particle.

Dreidel-like dislocations lead to remarkable properties

Dreidel-shaped dislocations put a new spin on two-dimensional materials for advanced electronics, hinting at sub-nanometer signal paths.

Breakthrough in biosensing: New virus detection method under development

Scientists have developed a method to detect the smallest virus particle. Since even one viral particle can represent a deadly threat, the research likely will make an important contribution to ongoing research on early detection of such diseases as AIDS and cancer.

Engineers develop new magnetoelectric computer memory

(Phys.org)—By using electric voltage instead of a flowing electric current, researchers from UCLA's Henry Samueli School of Engineering and Applied Science have made major improvements to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM.

Observation of novel behavior in magnetic material suggests fresh approach to studying fundamental quantum phenomena

The name Higgs has been the talk of the town this year, since the elusive 'Higgs boson'—an elementary particle that, among other things, endows other particles with mass—was discovered in the CERN research facility. Now, an international research team including Shigeki Onoda of the Condensed Matter Theory Laboratory, RIKEN Advanced Science Institute, Wako, Japan, has provided strong evidence that the same basic mechanism—the so-called Higgs mechanism—that endows particles with mass, is also at play in an entirely different system, namely a magnet.

Passing the alcohol test: Fundamental properties of molecules have not changed during the past seven billion years

The mass ratio of protons and electrons is deemed to be a universal constant. And rightly so, as the latest radio-astronomy observations of a distant galaxy have shown. Scientists used the 100-metre radio telescope in Effelsberg to measure absorption lines of the methanol molecule at a number of characteristic frequencies. The researchers analysed the spectrum of the simplest of all the alcohols in a very distant galaxy. The result: to a high degree of accuracy molecules and molecular matter have the same properties today as they did seven billion years ago.

NASA to Work With D.C. Public Schools to Mentor Students With Disabilities

NASA's Office of Education has entered into a memorandum of agreement with District of Columbia Public Schools (DCPS) to help foster science, technology, engineering and math (STEM) educational opportunities among high school students with disabilities.

NASA to Provide Dec. 17 Commentary as Twin Probes End Lunar Mission

NASA will provide live commentary of the scheduled lunar surface impacts of its twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft beginning at 2 p.m. PST (5 p.m. EST) Monday, Dec. 17.

Beating Heart of J-2x Engine Finishes Year of Successful NASA Tests

NASA on Thursday took another step toward human exploration of new destinations in the solar system. At the agency's Stennis Space Center in Mississippi, engineers conducted the final test-firing of the J-2X powerpack assembly, an important component of America's next heavy-lift rocket.
