Iceland invents energy-from-water machine
Now an Icelandic team has invented a radical device which can produce electricity from water. The Thermator could play a major role in the non-polluting economies of the future.
It works by something called the thermo-electric effect, which scientists have known about for many years. But while thermo-electric generators have mainly been used to power spacecraft, such as Voyager and Galileo using heat from radioactive materials, the Thermator is firmly rooted on Earth and works on nothing more than hot water.

Astronomer sees black hole eat star
It began like a routine measurement on a quasar, a somewhat boring look at the emissions from a distant, early galaxy -- but it turned out that the graduate student was actually watching a black hole swallow part of a star.
As he looked at the spectrum of light sent out by TEX 1726+344, the student at the University of Texas at Austin, Feng Ma, realized he was seeing something extraordinary.

Antibacterial Soap a Waste of Time, Experts Say
It may be virtually impossible to buy soap in the United States that is not "antibacterial," but such products are a waste of time, experts said on Thursday. Not only that, but their heavy use could contribute to a whole new breed of hard-to-kill superbugs, the researchers told a meeting of the Infectious Diseases Society of America.

Universe is 'doomed to collapse'
Forget the idea that we live in a youthful universe. If two American professors are correct, the cosmos is middle-aged. And it has not got an old age to look forward to. Despite what recent observations suggest, Professor Andrei Linde from Stanford University and his wife Professor Renata Kallosh say the universe will stop expanding and collapse in the relatively near future.

Sharp Unveils 'Computer-On-Glass' Display
Sharp Corp, Japan's largest maker of liquid crystal displays (LCDs), unveiled a screen Tuesday with microprocessor circuitry applied directly onto the glass, enabling it to function like a computer.
The company hopes to have products available by 2005 using the advanced circuitry, perhaps even a "display card" that could store data and be carried around for use with various gadgets from games machines to mobile phones to car navigation systems.

Wer angibt, hat mehr vom Leben
Um Körpergröße und damit einen höheren sozialen Rang vorzutäuschen, machen Pandabären beim Urinieren bisweilen einen Handstand. Das haben Wissenschafter um Angela White von der Zoological Society of San Diego im chinesischen Wolong-Naturreservat beobachtet.

Why are snowflakes symmetrical?
How can ice crystallizing on one arm 'know' the shape of the other arms on the flake?
Snowflakes are symmetrical because they reflect the internal order of the water molecules as they arrange themselves in the solid state (the process of crystallization). Water molecules in the solid state, such as in ice and snow, form weak bonds (called hydrogen bonds) to one another. These ordered arrangements result in the basic symmetrical, hexagonal shape of the snowflake. In reality, there are many different types of snowflakes (as in the cliché that 'no two snowflakes are alike'); this differentiation occurs because each snowflake is a separate crystal that is subject to the specific atmospheric conditions, notably temperature and humidity, under which it is formed.

Kalifornien meldet "explosionsartigen" Anstieg von Autismus-Fällen
Ein "explosionsartiger" Anstieg der Autismus-Fälle im US-Bundesstaat Kalifornien in den vergangenen 15 Jahren ist nicht das Ergebnis sich ändernder Diagnose-Kriterien. Auch die Verbesserung der Diagnose ist nicht der Grund des enormen Anstiegs um 273 Prozent zwischen den Jahren 1987 und 1998. "Autismus steigt in den USA und wir wissen nicht warum", erklärte der Erstautor der Studie, Robert S. Byrd vom M.I.N.D. Institute der University of Califonia/Davis.
