PASADENA, Calif.—Researchers at the California Institute of Technology (Caltech) have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space.
Just when you thought your clocks were keeping the accurate time, here comes another semi-annual round of throwing all of them off schedule.
That time-altering event, the return to Standard Time for most of the United States, puts clocks out of kilter -- or, some would say, back into kilter -- as of 2 a.m. Sunday, the first Sunday of November.
So maintain harmony with other clock-watchers, you should turn your clock back one hour before going to bed Saturday night.
Mental health epidemic predicted. A Sydney shrink claims that the world wide web could create a mental-health epidemic, with up to 10 per cent of adolescents at risk of addiction.
Lawrence Lam, a behavioural epidemiologist at the University of Sydney and the Children's Hospital at Westmead cited studies in Greece and the US which showed that eight per cent of adolescents could be classified as computer addicts. Lam conducted research in China where the problem was close to 14 per cent.
Researchers have figured out how to recreate the environment near a black hole in order to understand the processes that cause them to emit high energy X-rays.
An electromagnetic "black holeMovie Camera" that sucks in surrounding light has been built for the first time.
The device, which works at microwave frequencies, may soon be extended to trap visible light, leading to an entirely new way of harvesting solar energy to generate electricity.
Five months ago, someone cobbled together a spoof video about an iPhone app that could remotely unlock and start a car. Oh, how we laughed. Now, take one guess at what Viper SmartStart, an iPhone app announced today, actually does.
With the speed of computers so regularly seeing dramatic increases in their processing speed, it seems that it shouldn't be too long before the machines become infinitely fast -- except they can't.
A pair of physicists has shown that computers have a speed limit as unbreakable as the speed of light. If processors continue to accelerate as they have in the past, we'll hit the wall of faster processing in less than a century.
For quite some time, many people credited part of the rise of blogging to the fact that many folks in the tech industry found themselves out of work in the wake of the dot com bubble bursting. Suddenly there were lots of tech geeks, who were always online and had stuff to say -- and now plenty of extra time to say it. It didn't take long for a whole slew of tools to pop up to make that happen, and voila, blogging revolution.
Superconductors.ORG herein reports the observation of record high superconductivity near 254 Kelvin (-19C, -2F). This temperature critical (Tc) is believed accurate +/- 2 degrees, making this the first material to enter a superconductive state at temperatures commonly found in household freezers.
