Cell ‘organs’ get plastic upgrades

May 26, 2008

University of Basel researchers have built artificial polymer organelles (internal compartments in cells that carry out specialized metabolic functions) and added them to live human cells in a lab dish.

The 200-nanometers-wide capsule contained enzymes, just like natural organelles. The artificial organelle’s membrane can be chemically tuned to control which chemicals can pass through it and regulate the reactions inside.

Applications of an artificial organelle could include boosting… read more

British Concern to Help U.S. Track Terrorists

October 22, 2002

Autonomy information retrieval software will be used to provide an analysis system to help the United States government track suspected terrorists. The software is based on Bayesian statistical techniques, which can search for patterns of information across large masses of data.

New year, new vitamin C discovery: It ‘cures’ mice with accelerated aging disease

January 5, 2010

A team of Canadian scientists have found that vitamin C stops and even reverses accelerated aging in a mouse model of Werner’s syndrome, but the discovery may also be applicable to other age-related diseases,.

Stem cells join muscle, spinal cord cells in ‘human-on-a-chip’ simulation

November 24, 2011

University of Central Florida researchers, for the first time, have used stem cells to grow neuromuscular junctions between human muscle cells and human spinal cord cells, the key connectors used by the brain to communicate and control muscles in the body.

.The National Institutes of Health (NIH), the Defense Advanced Research Projects Agency (DARPA), and the Federal Drug Administration (FDA) have recently launched an ambitious… read more

Nanoscale optics may lead to advances in on-chip data transmission

September 15, 2005

Rice University researchers have discovered a universal relationship between the behavior of light and electrons, according to study co-author Peter Nordlander, professor of physics and astronomy and of electrical and computer engineering.

“We believe the relationship can be exploited to create nanoscale antennae that convert light into broadband electrical signals capable of carrying approximately 1 million times more data than existing interconnects.”

Intelligent Computers See Your Human Traits

May 30, 2008

By combining audio and visual data, Yongjin Wang from the University of Toronto and Ling Guan from Ryerson University in Toronto have developed a system that recognizes six human emotional states: happiness, sadness, anger, fear, surprise, and disgust.

Their system can recognize emotions in people from different cultures and who speak different languages with a success rate of 82%.

Emotion recognition systems help the computer to understand the… read more

Genes, Neurons, and the Internet Found to Have Some Identical Organizing Principles

November 5, 2002

Scientists have found several organizational patterns — “network motifs” — underlying genetic, neural, technological, and food networks.

The mathematical technique, first proposed by Dr. Uri Alon, of the Weizmann Institute this year, has now been shown to be applicable in a wide range of systems. Surprisingly, the team found two identical motifs in genetic and neural systems.

A solid case of entanglement

January 12, 2010

For the first time, physicists have convincingly demonstrated that physically separated particles in solid-state devices can be quantum-mechanically entangled.

The experiment, which used electrons in a superconductor in place of photons in an optical system, forming entangled “Cooper pairs” over a micron or so, was conducted by a team of physicists from France, Germany and Spain.

Computer users move themselves with the mind

September 28, 2005

Computer scientists have created a brain-computer interface that can read your thoughts. It allows you to stroll down a virtual street. All you have to do is think about walking.

The technology detects brain waves by using electrodes placed at strategic points on the scalp; they are positioned over brain areas known to be involved in moving specific body parts. The computer can then distinguish between signals corresponding to… read more

Mobile Robotic Arm Taught To Manipulate Objects Such As Scissors And Shears

June 5, 2008

University of Massachusetts Amherst researchers built a robotic arm that can approach unfamiliar objects such as scissors, garden shears, and jointed wooden toys, and learn how they work by pushing on them and observing how they change.

The arm can “see” its environment through a digital camera. After testing the new object, the arm stores how the objects move as a kinematic model, which can be used to perform… read more

Defining An Algorithm For Inventing From Nature

January 19, 2010

“If we can build more direct connections between bioengineering and the fields of ecology and basic organismal sciences–converging at a place you might call “econeering”–we could together meet urgent bioengineering needs more quickly, and direct resources toward basic science discovery,” say MIT scientists Edward Boyden and Brian Y. Chow, who are using econeering to pioneer a new area–the use of natural reagents to mediate control of biological processes using light,… read more

In HAL’s Footsteps

October 11, 2005

Real progress is being made in developing IT systems that do a better job of monitoring, analyzing, and fixing problems without human intervention.

Several server, software, and services vendors are making the creation of intelligent systems, such as IBM’s autonomic computing, and the equipment and software to go with them the underpinning of their enterprise-management development programs.

Hints of structure beyond the visible universe

June 10, 2008

Colossal structures larger than the visible universe — forged during the period of cosmic inflation nearly 14 billion years ago — may be responsible for a strange pattern seen in the big bang’s afterglow, says a team of cosmologists.

If confirmed, the structures could provide precious information about the universe’s earliest moments.

A Few Good Toys

December 4, 2002

The Army’s goal is to come up with a uniform by 2008 with helmet that enhances hearing and protect ears from battle cacaphony and heads-up display built into the visor to display infrared images. A wheeled robot “mule” would follow a soldier around with equipment for purifying water and recharging batteries.

The Army warfighter of 2025 will have lightweight body armor made with nanomaterials to deflect a bullet with… read more
