Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite.  Their findings will be published online in the prestigious international journal Science on January 22."It is counter-intuitive but the gold got harder instead of softer," says Miller.  Can you imagine a blacksmith heating up gold to pound it thinner, only to find it got...

Physicists at the Joint Quantum Institute (JQI) of the National Institute of Standards and Technology (NIST) and the University of Maryland have proposed a recipe for turning ultracold "boson" atoms"”the ingredients of Bose-Einstein condensates"”into a "supersolid," an exotic state of matter that behaves simultaneously as a solid and a friction-free superfluid. While scientists have found evidence for supersolids in complex liquid helium mixtures, a supersolid formed from such...

Laboratory researchers have posited an explanation for superconductivity that may open the door to the discovery of new, unconventional forms of superconductivity. In a November 20 Nature letter, research led by Tuson Park and Joe D. Thompson both of Condensed Matter and Thermal Physics (MPA-10) describes a new explanation for superconductivity in non-traditional materials"”one that describes a potentially new state of matter in which the superconducting material behaves simultaneously...

Imagine a plane that has wings made out of glass; thanks to a major breakthrough in understanding the nature of glass by scientists at the University of Bristol, this has just become a possibility. Despite its solid appearance, glass is actually a 'jammed' state of matter that moves very slowly. Like cars in a traffic jam, atoms in a glass can't reach their destination because the route is blocked by their neighbors, so it never quite becomes a 'proper' solid. For more than 50 years most...

A better understanding of material could bring 'endless applications'MIT physicists have taken a step toward understanding the puzzling nature of high-temperature superconductors, materials that conduct electricity with no resistance at temperatures well above absolute zero.If superconductors could be made to work at temperatures as high as room temperature, they could have potentially limitless applications. But first, scientists need to learn much more about how such materials work.Using a...

Physicists have created the state of matter thought to have filled the Universe just a few microseconds after the big bang and found it to be different from what they were expecting. Instead of a gas, it is more like a liquid. Understanding why it is a liquid should take physicists a step closer to explaining the earliest moments of our Universe. Not just any old liquid, either. Its collective movement is rather like the way a school of fish swims 'as one' and is a sign that the fluid...

June 22, 2005 Physicists at the Massachusetts Institute of Technology (MIT) have created the first example of a high-temperature superfluid: a new state of matter in which the atoms in a gas can move with no friction or slowing down whatsoever. Reported in the June 23 issue of journal Nature, the work is closely related to the superconductivity of electrons in metals. According to Wolfgang Ketterle, the Nobel laureate who heads the MIT group, observations of superfluids may help solve...

100 years after Einstein's landmark work on Brownian motion, physicists have discovered a new concept of temperature that could be the key to explaining how ice and snow particles flow during an avalanche, and could lead to a better way of handling tablets in the pharmaceutical industry. This research is reported today in a special Einstein Year issue of the New Journal of Physics  published jointly by the Institute of Physics and the German Physical Society (Deutsche Physikalische...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
The origin of 'barghest' is not known, but it may be from perhaps burh-ghest, town-ghost, or German Berg-geist (mountain spirit) or Bär-geist (bear-spirit).
