Kennedy Space Center on Standby to Support Toy Delivery Christmas Eve

Preparations are under way at NASA's John F. Kennedy Space Center in Florida to support Santa Claus during his annual tour, delivering toys and other presents to children all over the world.

NASA'S Space Launch System Core Stage Passes Major Milestone, Ready to Start Construction

The team designing America's new flagship rocket has completed successfully a major technical review of the vehicle's core stage.

Engineers seek ways to convert methane into useful chemicals

With natural gas production rising, engineers and scientists are seeking ways to convert methane into useful chemicals. A new study suggests a pathway.

Nanotechnology: Spotting a molecular mix-up

Information within the bonds of molecules known as super benzene oligomers pave the way for new types of quantum computers.

Paths of photons are random -- but coordinated

Researchers have demonstrated that photons (light particles) emitted from light sources embedded in a complex and disordered structure are able to mutually coordinate their paths through the medium. This is a consequence of the photons' wave properties, which give rise to the interaction between different possible routes.

New kind of magnetism discovered: Experiments demonstrate ‘quantum spin liquid'

Following up on earlier theoretical predictions, researchers have now demonstrated experimentally the existence of a fundamentally new kind of magnetic behavior, adding to the two previously known states of magnetism. The experiments demonstrate "quantum spin liquid," which could have applications in new computer memory storage.

Science's breakthrough of the year: Discovery of the Higgs boson

The observation of an elusive sub-atomic particle, known as the Higgs boson, has been heralded by the journal Science as the most important scientific discovery of 2012. This particle, which was first hypothesized more than 40 years ago, holds the key to explaining how other elementary particles (those that aren't made up of smaller particles), such as electrons and quarks, get their mass.

Are You Fit Enough to go to Space?

Doctors have taken a first stab at outlining medical advice for a type of travel that will likely become much more common in the years ahead: ordinary people taking trips to space.

The advice, published last week in the British Medical Journal, focuses on those individuals with pre-existing conditions who might want to travel to space. Conditions addressed range from the minor---motion sickness, insomnia---to chronic conditions like heart disease and osteoporosis. For motion sickness, for ins

The paths of photons are random, but coordinated

(Phys.org)—Researchers at the Niels Bohr Institute have demonstrated that photons (light particles) emitted from light sources embedded in a complex and disordered structure are able to mutually coordinate their paths through the medium. This is a consequence of the photons' wave properties, which give rise to the interaction between different possible routes. The results are published in the scientific journal, Physical Review Letters.

Researchers observe new unexplained particle states

In the vast particle landscape, there are, to borrow a phrase, known knowns (the Standard Model, for example), unknown unknowns (exotic extensions of the Standard Model and beyond), and those ever-interesting known unknowns. A recent CMS observation perfectly fits into this third category. When looking at proton collisions where a J/ψ and a φ meson are produced, CMS observed two unexplained peaks in the data. The first of these structures is consistent with a similar observation made by the CDF collaboration at the Tevatron in 2009, known as Y(4140).
