Swat Survival Kit in Waterproof Case
Titania nanotubes are 1,500 times better than the next best material for sensing hydrogen and may be one of the first examples of materials properties changing dramatically when crossing the border between real world sizes and nanoscopic dimensions, according to a Penn State materials scientist.

Attempting to improve on the face-center cubic lattice structure of opals in order to make 'photonic crystals,' an UCSD scientists experimented with ways to pack a small number of tiny spheres and discovered that the colloidal particle clusters they made have exotic structures predicted by mathematicians in 1995.

Scientists got their closest-ever ultraviolet look at the Sun from space, thanks to a telescope and camera launched aboard a sounding rocket. The images revealed an unexpectedly high level of activity in a lower layer of the Sun's atmosphere (chromosphere).

Gravitational radiation, ripples in the fabric of space predicted by Albert Einstein, may serve as a cosmic traffic enforcer, protecting reckless pulsars from spinning too fast and blowing apart, according to a report published in the July 3 issue of Nature.

Long before our Sun and Earth ever existed, a Jupiter-sized planet formed around a sun-like star. Now, 13 billion years later, NASA's Hubble Space Telescope has precisely measured the mass of this farthest and oldest known planet.

For almost 40 years, all subatomic particles have fit neatly into two categories: three-quark baryons, like protons and neutrons; or mesons, made up of one quark and one anti-quark. The new particle spotted at Jefferson Lab is a sort of baryon-meson hybrid with five quarks.
