Telescoping Carbon Nanotubes Can Make Flash Memory Replacment

November 14, 2008

Researchers at The University of Nottingham have used carbon nanotubes to make fast non-volatile memory.

Telescoping nanotubes promise ultrafast computer memory

February 15, 2007

University of California, Riverside have developed a conceptual design for a macroscopically addressable data storage device based on carbon nanotubes, which can be used as nonvolatile random access memory and for terabit solid-state storage.

The design involves inserting one hollow nanotube, closed at both ends, into a slightly larger one, open at both ends, creating a telescoping motion using an electrostatic charge. That contact between the nanotube and the… read more

Television Begins a Push Into the 3rd Dimension

January 6, 2010

With 3-D films like Avatar gaining traction at the box office, a 3-D television turf war is brewing in the United States, as manufacturers unveil sets capable of 3-D and cable programmers rush to create new channels for them.

Television Reloaded

May 23, 2005

It’s a transformation as significant as when we went from black-and-white to color — and it’s already underway. The promise is that you’ll be able to watch anything you want, anywhere — on a huge high-def screen or on your phone.

Another transition well underway is time-shifting, the ability to rearrange the schedule to watch programs at your convenience, not the networks’.

Television That Leaps Off the Screen

July 10, 2005

The first rear-projection, no-glasses 3-D television set has been developed by Deep Light of Santa Monica, CA.

“HD3D” television sets, with 1,280 lines of resolution, could be available by next year for $10,000, according to Deep Light’s co-founder Dan Mapes.

The design also uses multiple “blades” of video to enable one screen to show different programs to different viewers at the same time.

Telexistence robot avatar transmits sight, hearing and touch

TELESAR V, a  “telexistence” robot system being researched at Keio University, aims to free people from time and space constraints by using remotely operated robots to interact with the remote environment, reports DigInfoTV.

The operator uses a 3D head mounted display that covers the entire field of view, to see exactly what the robot can see, and also hear. The sense of touch, recorded using force vectors… read more

Tell It What You’re Searching For

March 24, 2004

Web surfers may be able to talk to their computers one day using a browser announced by Opera Software. The new browser incorporates IBM’s ViaVoice technology, enabling the computer to ask what the user wants and “listen” to the request.

The new browser will allow users to interact with the content on the Web in a more natural way and could open up the Internet to users physically unable… read more

Telltale DNA Bits Give Away Presence of Secretive Invaders

May 20, 2008

Joseph Fourier University researchers have detected the presence of an invasive species by analyzing its DNA, found in water samples.

They used special DNA primers (single strands of DNA that attach to target DNA so it can be copied) to amplify a part of the DNA chain that is unique to American bullfrogs, a highly invasive species in Europe.

The technique can detect DNA even in very low… read more

Telltale DNA sucked out of household dust (article preview)

June 2, 2008

In a finding reminiscent of the movie Gattaca, Virginia Commonwealth University researchers have identified human DNA in dust.

Though each sample contained just trillionths of a gram of DNA, it was enough for amplification and profiling via the DNA kits used in forensic labs.

The amount of DNA in dust is tiny and from so many people that singling out any individual is currently difficult.

Telomere shortening may be early marker of cancer activity

July 16, 2003

Telomere shortening may be one of the earliest and most prevalent changes on a cell’s path to cancer, according to two studies presented at the 94th Annual Meeting of the American Association for Cancer Research (AACR).

As cells divide and age, telomere DNA is lost and telomeres get shorter and shorter. The new study suggests that telomere dysfunction from the shortening may play a causal role in human intraepithelial… read more

Telstra chief hosts conference as hologram

May 28, 2008

In an Australian first, Telstra’s high definition “holographic” video projection system projected a life-sized, real-time hologram of an executive, who interacted with business executives at an Adelaide conference while he stood in front of cameras in Telstra’s Melbourne office.

Temperature-sensitive gel scaffold regenerates craniofacial bone

December 13, 2013

Rice University bioengineers have developed a hydrogel scaffold for regeneratomg craniofacial bone tissue. The hydrogel starts as a liquid, solidifies into a gel in the body, and liquefies again for removal.

The material developed in the Rice lab of bioengineer Antonios Mikos is a soluble liquid at room temperature that can be injected where needed. At body temperature, the material turns instantly into a gel to… read more

‘Temporal cloaking’ could bring more secure optical communications

June 7, 2013

Output for a particular sequence of ones and zeros.<br />
Although the binary data specified on the bottom of the plot are clearly detected<br />
when the cloak is off, the voltage swings indicative of bit transmission are<br />
suppressed to a nearly flat line when the cloak is on.

 

Purdue University researchers have demonstrated a method for “temporal cloaking” of optical communications, representing a potential tool to thwart would-be eavesdroppers and improve security for telecommunications.

“More work has to be done before this approach finds practical application, but it does use technology that could integrate smoothly into the existing telecommunications infrastructure,” said Purdue graduate student Joseph Lukens, working with … read more

Temporary tattoos could make ‘electronic telepathy,’ ‘telekinesis’ possible

Temporary electronic tattoos could soon help people fly drones with only thought and talk seemingly telepathically without speech over smartphones

The devices are less than 100 microns thick, the average diameter of a human hair. They consist of circuitry embedded in a layer or rubbery polyester that allow them to stretch, bend and wrinkle. They are barely visible when placed on skin, making them easy to conceal from others.

The devices can detect electrical signals linked with brain waves, and incorporate solar cells for power and antennas that allow… read more

‘Ten Commandments’ of race and genetics issued

July 18, 2008

A multidisciplinary group focused on contentious issues related to race, genetic markers and medicine has released a set of 10 guiding principles for the scientific community.

The group–ranging from geneticists and psychologists to historians and philosophers–was led by anthropologist Sandra Soo-Jin Lee of Stanford University.

The guidelines include “members of the same race may have different underlying genetics,” and “oversimplified science feeds popular misconceptions.”
