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

Finding Life Away From Earth Will be Tough Task

February 9, 2003

Using basic techniques to search for the simplest evidence of ancient life on Earth is the best approach to finding evidence of life elsewhere, according to University of Washington paleontologist Roger Buick.

Buick said fossil evidence of early life, whether from Earth or somewhere else, could be so tiny that it is at the limits of -– or beyond -– current capabilities in optic microscopic resolution. Those life forms… read more

Found: first amino acid on a comet

August 18, 2009

An amino acid, glycine, has been found on a comet for the first time, a new NASA analysis of samples from NASA’s Stardust mission reveals, confirming that some of the building blocks of life were delivered to the early Earth from space.

New security camera promises to protect, not reveal your body parts

March 10, 2008

ThruVision is developing a camera that passively images objects that emit Terahertz, or T-rays.

T-rays are “black body” radiation (between microwave and infrared on the spectrum) naturally emitted from all materials, including people. The camera collects these naturally occurring T-rays and processes them to form images that reveal concealed objects hidden under a person’s clothing without displaying physical body detail, the company says.

Consortium seeks to ramp nanoelectronics research

December 10, 2005

Seeking to accelerate nanoelectronics research in the United States, a consortium of companies has announced its first research grants under the Semiconductor Industry Association’s new Nanoelectronics Research Initiative (NRI). The goal is to demonstrate novel computing devices with critical dimensions below 10-nm.

The grants will fund the creation of two new university-based nanoelectronics research centers — one in California and the other in New York. The grants will also… read more

Who should explore space, man or machine?

February 20, 2003

A contest for dominance in space pits biology and brains against circuits and chips.

Scientists discover potential new drug delivery system

August 26, 2009

Using a peptide allows for an attached nanoparticle, such as a drug, to be delivered more effectively from the bloodstream into cells, similar to how viruses work.

Nanomaterials show unexpected strength under stress

March 13, 2008

University of Maryland-College Park and NIST researchers have discovered that materials such as silica that are quite brittle in bulk form behave as ductile as gold at the nanoscale.

At the macroscale, the point at which a material will fail or break depends on its ability to maintain its shape when stressed. The atoms of ductile substances are able to shuffle around and remain cohesive for much longer than… read more

DNA self-assembly used to mass-produce patterned nanostructures

December 23, 2005

Duke University scientists have used the self-assembling properties of DNA to mass-produce nanometer-scale structures in the shape of 4×4 grids, on which patterns of molecules can be specified.

They said the achievement represents a step toward mass-producing electronic or optical circuits at a scale 10 times smaller than the smallest circuits now being manufactured.

The smallest features on these square DNA lattices are approximately 5 to 10 nanometers,… read more

Second Episode of The Animatrix Released

March 5, 2003

The second episode of Animatrix, part of The Matrix’s world, is now available for downloading.

Lobsters teach robots magnetic mapping trick

September 2, 2009

University of Oulu, Finland computer scientist Janne Haverinen has designed a robot that can navigate using variations in the geomagnetic field, allowing for more precision than GPS satellites and at lower cost than vision systems.

The research was inspired by a report of a similar ability in lobsters.

The future of biomedicine: virtual humans

March 18, 2008

Scientists have recently provided a sneak preview of the future of biomedicine with a range of projects seeking to assemble virtual humans–or parts of them–on computers and “labs on a chip.”

The technology could usher in a new era of personalized medicine in which rapid tests tell doctors which treatments have the best chances of success for individual patients.

In addition, copying the brain’s chemistry is important for… read more

Mine robot bogged down in mud in West Virginia rescue

January 4, 2006

A robot designed to search mines during emergencies was bogged down by mud earlier Tuesday, and was temporarily out of service in efforts to locate 13 miners trapped in a West Virginia mine.

The rescue robot, developed for the federal Mine Safety and Health Administration, is 30 inches wide, 50 inches tall and was designed to find possible escape routes for those trapped inside and determine whether it’s safe… read more

Pythagoras Solar turns windows into panels of energy

June 28, 2011

Pythagoras Solar

Pythagoras Solar, a start-up based in San Mateo, California, is working on creating “solar windows” that could generate power for office buildings and shield offices from sunlight, thus reducing air conditioning costs, according to the San Francisco Chronicle.

Thin horizontal rows of silicon cells embedded between dual panes of glass catch light from above. And through a trick of optics, the window blocks direct sunlight from… read more

Undercover genes slip into the brain

March 24, 2003

A molecular Trojan horse that can slip past the brain’s defences has proved to be very effective at delivering genes, drugs and other compounds to the brains of primates. It could be used to treat a host of brain disorders, from Parkinson’s to epilepsy.
