Scientists squeeze more than 1,000 cores onto computer chip

January 5, 2011

Xilinx Virtex FPGA chip

Scientists at the University of Glasgow and the University of Massachusetts Lowell have created an ultra-fast 1,000-core computer processor.

They used a field programmable gate array (FPGA) chip, which can be configured into specific circuits by the user,  enabling the researchers to divide up the transistors within the chip into small groups and ask each to perform a different task.

By creating more than 1,000 mini-circuits within the… read more

Drugs could head off a flu pandemic — but only if we respond fast enough

August 4, 2005

If a strain of avian influenza emerges that can spread easily from person to person, could rapid deployment of antiviral drugs stop a local outbreak from becoming a global disaster?

Yes, conclude the most detailed modelling studies yet of an emerging pandemic — if the world can muster its scientific and logistical efforts quickly enough.

How Geckos Stick — New Find May Lead to New Glue

August 29, 2002
Copyright (c) 2000 Kellar Autumn

A team of biologists and engineers has cracked the molecular secrets of the gecko’s unsurpassed sticking power, opening the door for engineers to fabricate prototypes of dry, adhesive microstructures that work even underwater or in a vacuum.

The gecko’s amazing climbing ability, the researchers found, depends on weak molecular attractive forces called van der Waals forces (electrodynamic forces that operate over very small distances but bond to nearly any… read more

Reading Thoughts with Brain Imaging

February 19, 2009

Vanderbilt University researchers have reported that from functional magnetic resonance imaging (fMRI) data from visual areas of the brain alone, they could distinguish which of two images subjects were holding in their memory — even several seconds after the images were removed.

The study also pinpointed, for the first time, where in the brain visual working memory is maintained.

Nanodisk gene therapy

January 13, 2011

A team of scientists at the Universitat Autonoma de Barcelona (UAB) has demonstrated that the peptide R9, formed by a specific type of amino acid (arginine), can encapsulate genetic material, assemble itself with other identical molecules to form nanoparticles, and enter directly into the cell nucleus to release the material it contains. The nanoparticles have the shape of a disk, with a diameter of 20 nm. and a height of… read more

Task force to Study Societal Implications of Nanotech

August 16, 2005

The Center for Responsible Nanotechnology (CRN) has announced the charter members of a new Task Force to develop comprehensive policy recommendations for safe and responsible use of molecular manufacturing.

“Progress toward developing the technical requirements for desktop molecular manufacturing is moving faster than it was when we founded CRN two years ago,” said Mike Treder, Executive Director of CRN.

“The recent announcement of a Technology Roadmap for Productive… read more

Microchips in the Blood

September 18, 2002

Many of the promised genomic drugs will be impossible to swallow as pills. Instead, they will have to be injected in minute quantities at precise intervals for months at a time. Just the job for an implantable syringe-on-a-chip. Researchers in this field refer to their goal as intelligent drug delivery. The intelligence is derived from a piece of silicon one centimetre square. Etched in the silicon is a matrix of… read more

Cornell researchers create DNA buckyballs for drug delivery

August 29, 2005

Cornell University researchers have made DNA buckyballs that could be used for drug delivery and as containers for chemical reactions.

The buckyballs are made from a specially prepared, branched DNA-polystyrene hybrid. The hybrid molecules spontaneously self-assemble into hollow balls about 400 nanometers in diameter.

On the White Path

September 25, 2007

Scientists in India are reporting that have have made nanoscale crystals of cadmium sulfide that, when coated onto a light-emitting diode (LED), give off a white glow.

The LED emits light at ultraviolet wavelengths and the crystals produce the mix of colors that we perceive as white light.

Sandia National Laboratory estimates that if half of all lighting is based on LEDs by 2025, the world would use… read more

Darwin’s Theory May Explain Ill Health

October 11, 2002

Professor Randolph Nesse believes that conditions like heart disease, obesity and drug abuse can all be explained by the fact that the human body was not designed for the 21st Century. Nesse, professor of psychiatry at the University of Michigan, is one of the leading proponents of evolutionary or Darwinian medicine. Evolutionary medicine examines why some diseases still exist. According to Nesse, our bodies are designed to like things that… read more

Polymer breakthrough to boost smart drugs

September 12, 2005

Smart plastic films programmed to release a precise sequence of treatments are poised to revolutionize drug delivery, thanks to a breakthrough in polymer chemistry at MIT.

The films could be used to coat implants such as artificial hips and tissue scaffolds to deliver phased release over a period of hours or weeks.

The method calls for depositing very thin polymer films on objects of any shape. The scientists… read more
