Not your father’s periodic table
Revised periodic table slanted toward astronomers
The periodic table isn’t what it used to be, thanks to innovations by a planetary chemist at Washington University in St. Louis.
Katharina Lodders, Ph.D., Washington University research associate professor in Earth and Planetary Sciences in Arts & Sciences, has evalutated data from numerous studies including her own and arranged the data into a periodic table slanted toward astronomers and cosmochemists. It’s the Cosmochemic
A finite dodecahedral Universe
A franco-american quintet of cosmologists conducted by Jean-Pierre Luminet, from Paris Observatory (LUTH), has proposed an original explanation to account for a surprising detail observed in the Cosmic Microwave Background (CMB) recently mapped by the NASA satellite WMAP. According to the team, who published their study in the 9 october 2003 issue of “Nature”, an intriguing discrepancy in the background luminous texture of the Universe can indeed be explained by a very specific global shape of space
Metallic phase for bosons implies new state of matter
The Heisenberg uncertainty principle places severe constraints on the subatomic world. To illustrate, for particles called bosons, the principle dictates that bosons either condense to form a superconductor or they must remain localized in an insulator. However, experiments conducted during the last 15 years on thin films have revealed a third possibility: Bosons can exist as a metal. Scientists have been struggling to interpret this surprising result.
“The conventional theory of metals is
UCSB physicist devises way to observe protein folding
Physicists are getting more involved in the fight against diseases by studying the folding of proteins, which they hope will eventually lead to the development of new drugs. Illnesses such as Alzheimer’s disease and even some cancers are the result of protein folding that has gone awry. Since proteins in the body perform different functions according to their shape, the folding process is considered a very important area of study.

First extrasolar planets, now extrasolar moons
ESA is now planning a mission that can detect moons around planets outside our Solar System, those orbiting other stars!
Everyone knows our Moon: lovers stare at it, wolves howl at it, and ESA recently sent SMART-1 to study it. But there are over a hundred other moons in our Solar System, each a world in its own right.
A moon is a natural body that travels around a planet. Moons are a by-product of planetary formation and can range in size from small asteroid-sized bodies of a f
Lasers create new possibilities for biological technology
A team of researchers at the University of Colorado at Boulder has taken another step in the quest to build a compact, tabletop x-ray microscope that could be used for biological imaging at super-high resolution.
By firing a femtosecond laser – a laser that generates light pulses with durations as short as 100 trillionth of a second – through a gas-filled tube called a waveguide, they were able to create more efficient “laser-like” beams in regions of the spectrum that were previously inacc
