Practical Cloaking Devices On The Horizon?

August 11, 2008

University of California, Berkeley scientists have created a multilayered, “fishnet” metamaterial that unambiguously exhibits negative refractive index, allowing for invisibility in three dimensions for the first time, Nature magazine plans to report this week.

Small science to be big in 2005: analysts

January 21, 2005

“Nanotechnology” will be a much more familiar word to everyone in 2005, not just scientists, say analysts.

In 2005, people will start noticing its mundane uses, like making car paint shinier, windows that clean themselves, and smaller and better mobile batteries.

Micromachine manipulates cells

August 22, 2001

Sandia National Laboratories has created a micromachine that interacts at the scale of cells and could have important uses in genetic engineering and medicine.

The device uses silicon microteeth that open and close like jaws to momentarily trap individual cells to implant materials.

The ultimate goal of the Sandia device is to puncture cells and inject them with DNA, proteins, or pharmaceuticals to counter biological or chemical… read more

Real-Time Search

April 22, 2010

Google is on a quest to track and rank real-time (Facebook, Twitter, blogs, etc.) data to incorporate it into search results.

Google continuously scans for shifts in language and other deviations from predicted behavior. For example, users whose tweets are often retweeted by other users, or Facebook users with more friends can generally be assumed to have more authority.

Hollywood Hair is Captured at Last

August 15, 2008
The left two images demonstrate different aspects of a real hairstyle that the computer scientists captured. The third image from left is the reference photograph of the real hairstyle. The new algorithms created the image on the right, which has photorealistic highlights and texture, even through there are no photographs that were taken at that angle.

UC San Diego, Adobe, and MIT researchers have developed a new method for accurately capturing the shape and appearance of a person’s hairstyle for use in animated films and video games.

The researchers captured about 2,500 real-world images of hair using 16 cameras, 150 light sources and three projectors arranged in a dome setup. With this data, the computer scientists determined the physical position and orientation of… read more

Mirror that reflects your future self

February 3, 2005

Accenture Technology is developing an image-processing computer system that shows you what you will look like in five years’ time if you take no exercise, eat too much junk food and drink too much alcohol.

Cameras monitor your activity and a computer asks you to identify food eaten and other behaviors. The computer then calculates your likely future appearance and displays in on a flat-screen LCD TV.

‘Nimda’ virus outbreak spreads worldwide

September 19, 2001

Known as “Nimda” or “readme.exe,” a new worm spreads by sending infected e-mail messages, copying itself to computers on the same network, and compromising Web servers using Microsoft’s Internet Information Server (IIS) software. Infected Web pages may also download the worm to Web surfers’ PCs when they view the page.
Nimda started spreading early Tuesday morning and quickly infected PCs and servers across the Internet. It infects PCs running Windows… read more

MEMS device generates power from body heat

April 30, 2010

Thermoelectric power generator

A team of researchers from Singapore has developed an energy-harvesting device using stacked thermocouples that generates a few microwatts of electrical power from body heat or any environment where there is a temperature gradient.

By accumulating this energy over time, it could be used to prolong the battery life of electronic devices such as pressure sensors, and also recycle heat generated from the devices during operation. By… read more

Mozilla to challenge big players in mobile web

February 22, 2012


Mozilla is expected Wednesday to announce plans for Mozilla Marketplace, offering mobile apps for  the iPhone, an Android phone, or a Windows phone.

Mozilla is also working to develop a smartphone that would not be locked into the “walled gardens” of apps, operating systems and devices that are now controlled by Apple, Google, Microsoft, Amazon and a few others.

Mozilla’s vision is to develop a… read more

Watson vs Venter: the loser is race-based medicine

August 21, 2008

A new comparison of the publicly available genome sequences of James Watson and Craig Venter indicates that skin color doesn’t necessarily tell you much about the rest of their genome or how they’ll respond to drugs or which drugs they’ll respond to, says Venter.

But the availability of cheap genetic testing — and soon complete individual genome sequencing — means that such personalized information will become increasingly important in… read more

Augmented Reality: Another (Virtual) Brick in the Wall

February 16, 2005

Augmented Reality (AR) — a broad class of user interface techniques intended to enhance a person’s perception of the world around them with computer generated information — aims to enhance the analog world.

Users, via wearable display screens, see the non-virtual world around them with digital information superimposed into their surroundings.

Programs are also being developed that can make smart assumptions about what users want to do next.… read more

New Ideas in the War on Bioterrorism

October 10, 2001

Ideas for better technology to detect, diagnose and treat biological agents are currently being pursued in the nation’s newest medical battle -— the war against bioterrorism.
There are dozens of pathogens that might conceivably be used in an attack, including some unnatural ones made by genetic engineering, and it would be impractical to develop vaccines for all of them. So the new battle will be fought with the tools of… read more

How To Take Photographs Through Opaque Objects

May 6, 2010

Opague Imaging

Langevin Institute physicists have devised a way to reconstruct randomly scattered images to allow pictures to be transmitted (or viewed) through certain kinds of opaque objects.

Just send several known wavefronts through the material and record how they are distorted. The “transmission matrix” (how light is scattered by the opaque medium) can be deduced from the difference between the projected and transmittted wavefronts. Then send the inverse of the… read more

A Helping Hand for Surgery

August 28, 2008
(Timothy Leong/JHU)

Johns Hopkins University researchers have developed a tiny handlike gripper that can grasp tissue or cell samples and could make it easier for doctors to perform minimally invasive surgery, such as biopsies.

The device curls its “fingers” around an object when triggered chemically, and it can be moved around remotely with a magnet.

Alternate Reality Video Games Blur Many Lines

March 1, 2005

“Alternate-reality gaming” — an obsession-inspiring genre that blends real-life treasure hunting, interactive storytelling, coded web sites, video games and online community — may, incidentally, be one of the most powerful guerrilla marketing mechanisms ever invented.
