This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.
innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.
University of California, Berkeley, physicists can now tune in to and hear normally inaudible quantum vibrations, called quantum whistles, enabling them to build very sensitive detectors of rotation or very precise gyroscopes. Quantum whistle
Hear the synchronized vibrations from a chorus of more than 4,000 nano-whistles, created when physicists pushed superfluid helium-4 though an array of nanometer-sized holes. Note that the pitch drops as the pressure drops.

ESAs SMART-1 captured its first close-range images of the Moon this January, during a sequence of test lunar observations from an altitude between 1000 and 5000 kilometres above the lunar surface.
SMART-1 entered its first orbit around the Moon on 15 November 2004. It has spent the two months following spiralling down to the Moon and testing its array of instruments.
The first four days after being captured by the lunar gravity were very critical. There had been
Carbon nanotubes—a hot nanotechnology with many potential uses—may find one of its quickest applications in the next generation of standards for optical power measurements, which are essential for laser systems used in manufacturing, medicine, communications, lithography, space-based sensors and other technologies.
As described in a forthcoming paper in Applied Optics,* scientists at the National Institute of Standards and Technology (NIST) and the National Renewable Energy
A key process that enhances the production of nuclear energy in the interior of dense stars has been re-created in the laboratory for the first time by physicists at the National Institute of Standards and Technology (NIST). The work may help scientists study topics such as nuclear fusion as a possible energy source and demonstrates a new method for studying and modeling dense stellar objects such as white dwarfs.
The NIST experiments, described in the Jan. 18 issue of Physical Revi
Clear evidence in a Chinese meteorite for the past presence of chlorine-36, a short-lived radioactive isotope, lends further support to the controversial concept that a nearby supernova blast was involved in the formation of our solar system, according to a report forthcoming in the February 1 issue of the Proceedings of the National Academy of Sciences (to be published online today).
Known as the Ningqiang carbonaceous chondrite, the primitive meteorite is a space relic that fo
These images from the Huygens DISR instrument show new features, such as evidence of flow around ’islands’, deposits of water ice and channels which could have been created by methane springs.
