Sci-Fi War Uniforms?

February 25, 2003

MIT’s new Army-funded Institute for Soldier Nanotechnologies is designing the perfect uniform protection for soldiers, using nanotech.

Designs will include “smart surfaces” that can change from being water-repellent to water-absorbent, fibers that can be woven into a soldier’s uniform to make it identifiable even in the dark, and the ability to adapt to biological and chemical threats.

Science copies how squid change color

January 23, 2012

squid

The gene that gives squids the ability to change color and camouflage themselves has attracted the attention of geneticists at Cambridge University working in the new science of synthetic biology. They have used standardized DNA sequences known as Bio-Bricks to recreate the gene so that future biologically engineered organisms could be given the same ability to change color.

Discovery Brings New Type Of Fast Computers Closer To Reality

September 28, 2009

UC San Diego physicists have created integrated circuits with particles called “excitons” at 125 degrees Kelvin (can be easily attained commercially with liquid nitrogen), bringing the possibility of a new type of extremely fast computer based on excitons closer to reality.

Excitons are pairs of negatively charged electrons and positively charged holes that can be created by light in a semiconductor such as gallium arsenide. When the electron and… read more

Gyroscope sets course to fight cancer

December 26, 2005

Micro-gyroscopes can make sensitive biosensors for fast detection of the proteins associated with diseases by measuring the subtle change in vibration caused when a protein binds to a DNA coating.

The researchers plan to produce hand-held devices to test blood, smear and biopsy samples and immediately relay the results to a doctor.

Matrix-style virtual worlds ‘a few years away’

April 4, 2008

Are supercomputers on the verge of creating Matrix-style simulated realities?

Michael McGuigan at Brookhaven National Laboratory thinks so, and has used the Lab’s Blue Gene/L supercomputer to generate a photorealistic, real-time artificial world. He found that conventional ray-tracing software could run 822 times faster on the Blue Gene/L than on a standard computer, allowing it to convincingly mimic natural lighting in real time.

The ultimate objective is to… read more

Breakthrough in detecting single DNA mutations

Could help treat diseases like tuberculosis and cancer

Researchers have developed a new method that can look at a specific segment of DNA and pinpoint a single mutation, which could help diagnose and treat diseases such as cancer and tuberculosis.

Modern genomics has shown that just one mutation can be the difference between successfully treating a disease and having it spread rampantly throughout the body.

These small mutations can be the root of a… read more

Iraq to Assist with Robot Testing

March 10, 2003

Iraq seems to be on the verge of becoming one of the biggest testing grounds for military robotics in history.

Two New Apps Superimpose Wikipedia Over Your iPhone Camera View of the World

October 5, 2009

Two new apps with Wikipedia entries about physical locations that you can view through your iPhone 3GS camera are now available, using the phone’s GPS and compass features.

Wikitude allows anyone to add notes on locations.

Computers estimate emotions

January 9, 2006

Researchers at the Fraunhofer Institute for Computer Graphics Research in Germany have developed a glove that senses a computer operator’s heartbeat and breathing rate, blood pressure, skin temperature and electrical resistance and connects to a device that infers emotions.

They are also working on techniques that will enable computers to interpret facial expressions and extract emotional elements from voice signals.

Transplanted cells could ‘catch’ Parkinson’s

April 8, 2008

Perplexing new studies from Rush University Medical Center and Wallenberg Neuroscience researchers suggest cells transplanted into the brains of people with Parkinson’s disease (to produce dopamine) “catch” the disorder from the surrounding tissue.

They studied brains of three people who’d received grafts between 11 and 16 years before death. Some cells in the grafts contained structures called Lewy bodies, a hallmark sign of the disease. Most grafted neurons were… read more

3D IR images now in full color

August 7, 2013

Spectro-microtomographic images of a human hair show absorptions of protein (red) and phospholipid (blue-green). Center, the medulla is observed to have little protein. Bottom, the medulla has higher concentrations of phospholipids.

Researchers have created a non-destructive 3D imaging technique that provides molecular-level chemical information of unprecedented detail on biological and other specimens with no need to stain or alter the specimen.

Developed by researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of Wisconsin-Milwaukee (UWM), the technique combines Fourier Transform Infrared (FTIR) spectroscopy with computed tomography (CT-scans).

“The… read more

Trapped ions make logic gates

March 27, 2003

Two independent research groups report the creation of logic gates using pairs of “entangled” trapped ions. The researchers believe that these logic gates could be scaled up to include many qubits in a large, workable quantum computer.

Growing geodesic carbon nanodomes

October 12, 2009

Graphene sheets of carbon growing on a surface of iridium grow by first forming tiny carbon domes, researchers in Italy, the UK and USA have discovered, pointing the way to possible methods for assembling components of graphene-based computer circuits, replacing silicon and metal.

The study suggests that graphene grows in the form of tiny islands built of concentric rings of carbon atoms. The islands are strongly bonded to… read more

Sandia Labs developing nanobattery implant

Schematic of nanobattery that would be implanted in or near the eye

Sandia National Laboratories researchers are developing a nano-size battery that one day could be implanted in the eye to power an artificial retina. The artificial retina and accompanying nanobattery will be used to correct certain types of macular degeneration.

“We will use our expertise in multi-scale modeling to understand and predict how transporter structure leads to function, with an initial focus on specialized transporters found in the… read more

RSA — Top botnets control 1M hijacked computers

April 11, 2008

Botnets control just over a million hacked computers on the Internet and are capable of flooding the Internet with more than 100 billion spam messages every day, Joe Stewart, director of malware research at SecureWorks, said at the RSA Conference Thursday.

A botnet is a collection of software robots, or bots, that run autonomously and automatically on groups of hacked
“zombie” computers, controlled remotely.
