3-D Space as New Frontier

October 4, 2000

Steve Kash is living in his own little world, but guests are welcome to drop in for a chat. Flyby’s Hangar is the three-dimensional structure Mr. Kash calls home on the World Wide Web. Visitors can circle the music room, then scoot up a set of stairs and take an elevator to the roof garden, where a brook burbles loudly.

Mr. Kash’s walls are bare. A Guggenheim curator, Matthew Drutt, on the other hand, has nothing but art in the Guggenheim Virtual Museum, a three-dimensional gallery that is expected to open to the Webgoing public before the year ends. Mr. Drutt declined to describe the museum’s vertical surfaces as walls, though. “I think more in terms of skins,” he said, “because the art is visible from the outside as… read more

Homeland Security Funds LED Light Saber

July 27, 2007

The Department of Homeland Security is funding the creation an LED flashlight that uses powerful flashes of light to temporarily blind, disorient and incapacitate people.

Homeland Security’s Science and Technology arm hopes government agents can use the “light saber” to arrest people on planes and at the borders without using traditional weapons.

The LED Incapacitator uses a range-finder to measure the distance to a target’s eyes and then… read more

How to erase a memory

November 2, 2010

Johns Hopkins University School of Medicine researchers have discovered that by removing a protein from the region of the brain involved in recalling fear (the amygdala), using drugs and behavioral therapy, they can permanently delete traumatic memories for such conditions as post-traumatic stress disorder.

Richard L. Huganir, Ph.D., professor and director of neuroscience at the Johns Hopkins University School of Medicine and a Howard Hughes Medical… read more

Inkjet printing promises cheaper circuits

November 4, 2004

Epson has developed a circuit-making technology based on inkjet printing, firing droplets of conducting “ink” or insulating “ink” onto a circuit board to make a circuit that is 20 millimeters square, 200 microns thick, and consists of 20 individually printed layers.

Epson estimates inkjet-printed circuits should be about half as expensive to make as current circuitry and also less environmentally harmful. They expect in the future that it will… read more

Obama Renovates WhiteHouse.gov

January 21, 2009

The new whitehouse.gov site will “publish all non-emergency legislation to the Web site for five days, and allow the public to review and comment before the President signs it,” along with more “timely and in-depth content” about the administration’s policies, including blogs and e-mail alerts.

Carbon nanotube integrated circuit developed

April 3, 2001

A carbon nanotube integrated circuit, with a thousand nanotubes acting like transistors, has been devised by IBM, as reported in Physics News.

Besides their small size, nanotubes are strong and can withstand high current densities and heat, allowing for high packing density.

First Armed Robots on Patrol in Iraq

August 3, 2007

For the first time in the history of warefare, robots with guns have been deployed.

Three “special weapons observation remote reconnaissance direct action system” (SWORDS) robots have deployed to Iraq, armed with M249 machine guns.

Nano Fabric May Make Computers Thinner

November 19, 2004

Researchers in Russia and England claim they have discovered the world’s first single-atom-thick fabric.

The fabric may represent a new class of materials — so thin they are only two-dimensional — and may lead to computers made from a single molecule.

The graphene fabric is the first two-dimensional fullerene. The research team demonstrated an “ambipolar field-effect” that makes graphene a transistor under ambient temperature and pressure conditions.… read more

How do we know the LHC really is safe?

January 28, 2009

A new analysis by researchers at the Future of Humanity Institute at the University of Oxford paper on the risks associated with extremely rare but potentially catastrophic events finds that the estimated probability of a “dangerous event” (such as annihilation of the Earth by creating a tiny black hole) at the Large Hadron Collider of around 10^9 per year is questionable, because this figure represents the chance of a dangerous… read more

Disney Research creates 3D-printed interactive speakers of any shape

April 30, 2014

3d printed speaker

Scientists at Disney Research, Pittsburgh have developed methods to use a 3D printer to produce electrostatic loudspeakers that can take the shape of anything, from a rubber ducky to an abstract spiral.

The simple speakers require little assembly, but even those few manual steps might be eliminated in the future, said co-developer Yoshio Ishiguro, a Disney Research, Pittsburgh post-doctoral associate. “In five to 10 years, a 3D… read more

IBM nanotubes may enable molecular-scale chips

April 27, 2001

IBM researchers have developed a bulk process for producing nanotube transistors only 10 atoms wide, or 500 times smaller that current silicon transistors.

“We believe IBM has now passed a major milestone on the road toward molecular-scale chips,” said Thomas Theis, director of physical sciences at IBM’s Thomas J. Watson Research Center here. “Our researcher’s study [to be published Friday (April 27)] in Science magazine proves that… read more

Hitachi’s Deskstar 7K1000 hard drive: The Terabyte has landed

August 13, 2007

Hitachi’s Deskstar 7K1000 is the first 3.5″ hard drive to achieve terabyte-capacity — 33 percent greater than that of its competitors.

US review rekindles cold fusion debate

December 3, 2004

Claims of cold fusion are intriguing but not convincing, according to the findings an 18-member scientific panel tasked with reviewing research in the area.

The findings, released on 1 December by the US Department of Energy, rekindle a 15-year-old debate over whether nuclear fusion can occur at room temperature. The panel was “split approximately evenly” on the question of whether cold experiments were actually producing power in the form… read more

The cockpit of the future

February 3, 2009

German research scientists have developed a novel car dashboard that functions as a 3-D display and shows velocities, engine speeds, and warnings in three dimensions.
