World's smallest radio uses single nanotube to pick up good vibrations
10-31-2007 · EurekAlert!Wielding a single carbon nanotube 10,000 times smaller than a human hair, UC-Berkeley and LBNL physicists have constructed the smallest radio yet. The nanotube vibrates at radio frequencies to receive the signal, then acts as both amplifier and demodulator. With only a battery and sensitive earphones, it can pick up AM or FM. With such a small receiver or transmitter, you could put a tracking collar on a bacterium.

- Make way for the real nanopod
10-31-2007 · EurekAlert!
Make way for the real nanopod and make room in the Guinness World Records. A team of researchers with the US Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the first fully-functional radio from a single carbon nanotube, which makes it by several orders of magnitude the smallest radio ever made.

- World's smallest radio fits in the palm of the hand...of an ant
11-01-2007 · EurekAlert!
Harnessing the electrical and mechanical properties of the carbon nanotube, a team of researchers has crafted a working radio from a single fiber of that material.Fixed between two electrodes, the vibrating tube successfully performed the four critical roles of a radio -- antenna, tunable filter, amplifier and demodulator -- to tune in a radio signal generated in the room and play it back through an attached speaker.

- Toward world's smallest radio: nano-sized detector turns radio waves into music
10-17-2007 · EurekAlert!
Researchers in California report development of the world's first working radio system that receives radio waves wirelessly and converts them to sound signals through a nano-sized detector made of carbon nanotubes. The 'carbon nanotube radio' device is thousands of times smaller than the diameter of a human hair. The development marks an important step in the evolution of nano-electronics and could lead to the production of the world's smallest radio, the scientists say.

11-08-2007 · EurekAlert!
Researchers at NIST and George Mason University have demonstrated what is probably the world's smallest microwave oven, a tiny mechanism that can heat a pinhead-sized drop of liquid inside a container slightly shorter than an ant and half as wide as a single hair.

- The world's smallest double slit experiment
11-08-2007 · EurekAlert!
Where do the realms of quantum mechanics and classical physics begin to overlap? It's a long-argued question of philosophical interest and practical importance. Now the world's smallest double slit experiment, performed at Lawrence Berkeley National Laboratory's Advanced Light Source and using as "slits" the two proton nuclei of a hydrogen molecule, has shown that quantum particles start behaving in a classical way on a scale as small as a single hydrogen molecule.

- NIST's stretching exercises shed new light on nanotubes
04-12-2007 · EurekAlert!
Stretching a carbon nanotube composite like taffy, researchers at NIST and the Rochester Institute of Technology have made some of the first measurements of how single-walled carbon nanotubes both scatter and absorb polarized light, a key optical and electronic property.

- HIV's path out of Africa: Haiti, the US then the world
10-29-2007 · EurekAlert!
The AIDS virus entered the United States via Haiti, probably arriving in just one person in about 1969, earlier than previously believed, according to new research. The research is the first to definitively pinpoint when and from where HIV-1 entered the United States, and shows that most HIV/AIDS viruses in the US descended from a single common ancestor.

Visitors to Supercomputing '06 in Tampa, Fla., this week will be the first to see a new interactive map that shows nine of the world's largest computing grids. The map, developed by researchers from GridPP in the UK and the European particle physics laboratory, CERN, in Geneva, uses Google Earth to pinpoint grid sites on six continents, showing more than 300 sites overall like the medieval "mappa mundi."
