Stem Cells Made From ‘Dead’ Human Embryo

September 26, 2006

Scientists say they have created a stem cell line from a human embryo that had stopped developing naturally, and so was considered dead. Using such embryos might ease ethical concerns about creating such cells, they suggested.

Human Eye Inspires Advance In Computer Vision

June 23, 2009

Inspired by the behavior of the human eye, Boston College computer scientists have developed a technique that lets computers see objects as fleeting as a butterfly with nearly double the accuracy and 10 times the speed of earlier methods.

Earthquake? Terrorist bomb? Call in the AI

May 24, 2011

In the chaos of large-scale emergencies, AI software could help direct first responders.

The “Rescue” system developed by researchers at Durham University, UK, comprises up to 4000 individual software agents that represent the public and members of emergency services, programmed with behaviors such as “help an injured person.”

Researchers at the University of Notre Dame have built a detailed simulation of how crowds respond to disaster. The Dynamic Adaptive… read more

Plan for UN to run internet ‘will be shelved’

November 11, 2003

An attempt by developing countries to put management of the internet under United Nations auspices is likely to be shelved at next month’s world information summit in Geneva — but the issue is now firmly on the international agenda, summit sources say.

Defenders of the status quo say handing over power to governments could threaten the untrammelled flow of information and ideas that many see as the very essence… read more

Sniffling mice raise therapy hope

February 5, 2008

In a study led by London’s Imperial College, scientists have created a mouse that can catch a cold, raising hopes of new ways to treat serious respiratory conditions and asthma.

It had been thought rhinoviruses, which cause most human colds and can trigger asthma attacks, could only affect higher primates.

Rhinoviruses were discovered 50 years ago, but the failure to find a way to infect small animals had… read more

HP’s Memory Spot Chip is Spot On

October 10, 2006

A prototype of a tiny wireless chip capable of storing and transmitting data was recently revealed by HP.

HP’s Memory Spot Chip reads sound from a picture

When the new chip hits the market in about two years, it will enable a variety of applications ranging from digital wristbands that store patient medical information to a new form of storing digital versions of documents or sound bytes on… read more

Toyota Develops Mind-Controlled Wheelchair

June 30, 2009

Toyota researchers have built a brain/machine interface that controls a wheelchair using EEG sensors placed over the areas of the brain that control motion, with plans for a wide range of applications in medicine and nursing care.

Senate approves nanotech bill

November 20, 2003

The Senate passed a version of its 21st Century Nanotechnology Research and Development Act. It gives nanotech a permanent home in the federal government, putting the National Nanotechnology Initiative into law and authorizing nearly $3.7 billion over four years for research and development.

Human species ‘may split in two’

October 18, 2006

Humanity may split into two sub-species in 100,000 years’ time, as predicted by H.G. Wells, says evolutionary theorist Oliver Curry of the London School of Economics.

He expects a genetic upper class would be tall, slim, healthy, attractive, intelligent, and creative and a far cry from the “underclass” humans, who would have evolved into dim-witted, ugly, squat goblin-like creatures.

But in the nearer future, humans will evolve in… read more

In Chrome, Hints of a Real Rival to Windows

July 9, 2009

Google promises that its free Chrome operating system, which will be available on computers in the second half of next year, will put an emphasis on speed, simplicity and security.

In Google’s view, Web connections will become so fast and browsers so powerful that most of the programs that currently run on PCs will be replaced by online applications. That would eliminate the need to install, upgrade and back… read more

Researchers create nanoparticles perfectly formed to tackle cancer

June 6, 2011

Researchers from the University of Hull have discovered a way to load up nanoparticles with large numbers of light-sensitive molecules to create a more effective form of photodynamic therapy (PDT) for treating cancer.

The nanoparticles were designed to be the perfect size and shape to penetrate easily into a tumor, the researchers said.

Most PDT works with individual light-sensitive molecules, but the… read more

Materials could make for super LEDs, solar cells, computer chips

December 3, 2003

Engineers at Ohio State University have created special hybrid materials that are virtually defect-free — an important first step for making ultra-efficient electronics in the future.

They grow thin films of “III-V” semiconductors, which absorb and emit light much more efficiently than silicon, so these materials could bridge the gap between traditional silicon computer chips and light-related technologies, such as lasers, displays, and fiber optics.

The engineers have… read more

Wiring Up DNA, Detecting Mutations

February 13, 2008

Caltech and Columbia University researchers have measured DNA’s ability to conduct electricity by wiring it up between two carbon nanotubes, creating a new way to detect mutations.

Introducing just a single letter change can drastically alter DNA’s resistance, a phenomenon that they plan to exploit with a device that can rapidly screen DNA for disease-linked mutations.

Vision-body link tested in robot experiments

October 30, 2006

“Embodied cognition” experiments involving real and simulated robots suggest that the relationship between physical movement and sensory input could be crucial to developing more intelligent machines.

Brain Surgery Using Sound Waves

July 21, 2009
(University Children

InSightec, a new ultrasound device, used in conjunction with MRI or CT, allows neurosurgeons to precisely burn out lesions deep in the brain without cutting the skin or opening the skull.

The InSightec device consists of an array of more than 1,000 ultrasound transducers, each of which can be individually focused.
