Magnetism
(Preview)
Magnetism observed in a gas for the first time For the first time, MIT scientists have observed ferromagnetic behavior in an atomic gas, addressing a decades-old question of whether it is possible for a gas to show properties similar to a magnet made of iron or nickel. The MIT team observed the behavi...

Nuclear fission
(Preview)
The discovery of a new type of fission turns a tenet of nuclear theory on its head. The observation of an unexpected nuclear reaction by an unstable isotope of the element mercury has thrown up a rare puzzle. The enigma is helping theorists to tackle one of the trickiest problems in physics: developin...

The curved sabres used by Muslims against Christian knights in the crusades may have been deadly because Muslim blade-makers used a form of nanotechnology, the steel coming from India, say German experts.
The Damascus blades wielded by Muslim fighters, renowned for their exceptional strengt...

(Preview)
An experiment suggests that a fundamental constant of nature, called mu, the mass ratio of two fundamental subatomic particles has decreased over the last 12 billion years.
The startling finding comes from a team of scientists from the Free University in Amsterdam in the Netherlands and the E...

Liquid motion
(Preview)
Mathematics research could point to new understanding of liquid motion. Droplets of liquid have been shown to travel uphill when the surface is vigorously shaken. In a similar process to raindrops on car windscreens, small ones stay in place while bigger ones roll down the window. This is due to th...

(Preview)
In 2004 to 2005, a series of articles was published by different authors about fullerene toxicity, the series being initiated with reports by E. Obersdorster from Dallas University (USA) and V. Colvin from Rice University. It was noted in particular that the fish swimming in the water with the full...

Chicago Pile-1
(Preview)
Chicago Pile-1 (CP-1) was the world's first human-made nuclear reactor. CP-1 was built on a rackets court, under the abandoned west stands of the original Alonzo Stagg Field stadium, at the University of Chicago. The first self-sustaining nuclear chain reaction was initiated in CP-1 on December...

Binary mass ratios
(Preview)
Title: Binary mass ratios: system mass not primary mass Authors: Simon P. Goodwin (Sheffield) Binary properties are usually expressed (for good observational reasons) as a function of primary mass. It has been found that the distribution of companion masses -- the mass ratio distribution -- is d...

Transparent glass mirror

Although windows can naturally heat buildings in the cold seasons, during the summer they can easily overheat a building. To help with this problem, Japanese scientists at AIST recently developed a thin film which can make transparent glass turn into mirrors. The use of such a window in buildings o...
