MIT develops 'tractor beam' for cells, more
In a feat that seems like something out of a microscopic version of Star Trek, MIT researchers have found a way to use a "tractor beam" of light to pick up, hold, and move around individual cells and other objects on the surface of a microchip. view more (2007-10-31)
Children's Hospital researchers identify genetic mutation that may predict organ rejection
Using a novel combination of cutting-edge technologies to scan the human genome, researchers at Children's Hospital of Pittsburgh of UPMC have identified a genetic mutation that identifies transplant recipients who experience rejection. view more (2008-09-16)
Prediction of gene function in mammals
Gene function in mammals can be quickly and reliably predicted using a high-throughput analysis of patterns of RNA expression, according to an article published today in Journal of Biology. This challenges the conventional view that tissue-specificity is the best predictor of function, and could speed up the quest to understand whole genomes, in... view more... (2004-12-02)
Quantum computer chips now 1 step closer to reality
In the quest for smaller, faster computer chips, researchers are increasingly turning to quantum mechanics -- the exotic physics of the small. The problem: the manufacturing techniques required to make quantum devices have been equally exotic. That is, until now. view more (2009-10-16)
MIT: New material could lead to faster chips
New research findings at MIT could lead to microchips that operate at much higher speeds than is possible with today's standard silicon chips, leading to cell phones and other communications systems that can transmit data much faster. view more (2009-03-24)
DECREASE IN AIDS-RELATED ILLNESS IN EUROPE (p 291)
During 1996 and 1997, highly active antiretroviral therapy (HAART) was introduced to treat HIV-1-infected patients who had low CD4-cell counts. In this week's issue of THE LANCET, A Mocroft and colleagues report findings from the EuroSIDA study, which looked at the change in incidence of AIDS-defining illnesses (ADIs) since the introduction of... view more...

Study finds value in 'junk' DNA
For about 15 years, scientists have known that certain "junk" DNA -- repetitive DNA segments previously thought to have no function -- could evolve into exons, which are the building blocks for protein-coding genes in higher organisms like animals and plants. view more (2008-10-17)
Identifying proteins with new microchip surfaces. Protein-binding nanoparticles simplify MALDI-TOF mass spectrometry
How does life function? In biology today, this is the question about the interplay between the countless molecules that make up all life forms. For example, if the interactions of proteins are interfered with, this can be a cause of illnesses. Nowadays, bio-chips are being used to an increasing extent to research these molecular interactions.... view more... (2003-08-06)
Minor mutations in avian flu virus increase chances of human infection
The H5N1 avian influenza virus, commonly known as "bird flu," is a highly contagious and deadly disease in poultry. view more (2006-03-20)
Cold virus found to manipulate genes
Sneezing, runny nose and chills? You might blame the human rhinovirus (HRV), which causes 30 to 50 percent of common colds. But in reality, it's not the virus itself but HRV's ability to manipulate your genes that is the true cause of some of the most annoying cold symptoms. view more (2008-10-27)
Chalmers first with integrated receiver for high frequency applications
As the first research group in the world, researchers at Chalmers have succeeded in combining a receiver for high frequencies with an antenna on a small chip. view more (2007-11-29)
Working together to design robust silicon chips
Designers of high-speed silicon chips have often had to compromise on performance levels for their integrated circuit designs because of physical weaknesses appearing during design verification or even in production. view more (2009-11-13)
New Chip Design Delivers Better Performance, Longer Battery Life for Cell Phones, WiFi, and Other Wireless Communications
Anyone who uses a cell phone or a WiFi laptop knows the irritation of a dead-battery surprise. view more (2006-04-20)
Chips are down as Manchester makes protein scanning breakthrough
Scientists at The University of Manchester have developed a new and fast method for making biological 'chips' - technology that could lead to quick testing for serious diseases, fast detection of MRSA infections and rapid discovery of new drugs. view more (2008-08-25)
Scientists Image 'Magnetic Semiconductors' On The Nanoscale
In a first-of-its-kind achievement, scientists at the University of Iowa, the University of Illinois at Urbana-Champaign and Princeton University have directly imaged the magnetic interactions between two magnetic atoms less than one nanometer apart (one billionth of a meter) and embedded in a semiconductor chip. view more (2006-07-27)
Star technology aids DNA analysis
University of Leicester astronomers and biologists have patented a new way of analysing DNA from gene-chips, which may be used in laboratories and hospitals to diagnose diseases from a single drop of blood and compare gene expression in different samples. The pioneering technique uses an instrument developed at the European Space Agency's... view more... (2003-11-03)
Building a hand-held lab-on-a-chip to simplify blood tests
A cell phone-sized blood-count machine requiring less blood than a mosquito bite will make blood tests easier for many patients, from neonatal units to astronauts in space. view more (2006-04-13)
Researchers identify gene set linked to breast cancer's spread to lungs
In a potential advance for the treatment of aggressive breast cancer, scientists at Memorial Sloan-Kettering Cancer Center (MSKCC) have identified a set of genes in breast tumors that appear to predict if the disease will spread to the lungs and, once there, how virulent it will become. view more (2005-07-28)
Three new lung tumor subtypes identified in DNA profiling study
A new study has identified three subtypes of non-small-cell lung cancer tumors, a finding that may provide valuable clinical information about patient survival in early- or late-stage disease, how likely the cancer is to spread and whether the tumor will prove resistant to chemotherapy. view more (2006-10-31)
Chameleon-chip adapts itself and stays cool
A microprocessor adapting itself to the actual use and environment. That's the way to keep the energy consumption of future 'mobile companions' within limits and be flexible at the same time. Paul Heysters, who finishes his PhD-research at the University of Twente on September 24, developed a new type of processor. His 'Montium' is a... view more... (2004-09-22)
