Probing biology's dark matter
A typical human mouth teems with as many as 700 different species of microbes. A handful of these have been specifically implicated in promoting gum disease, dental cavities, and bad breath, but for the most part, the make-up of this complex ecosystem and its impact on human health remain largely unexplored. view more (2007-07-20)
Perfect image without metamaterials ... and a reprieve for silicon chips
Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd directions to create, among other tricks of the light, the illusion of invisibility. view more (2009-09-29)
Breakthrough Chip Delivers Better Digital Pictures For Less Power
The next advance in cameras is becoming a reality at the University of Rochester. Imaging chips revolutionized the photography industry, and now the chips themselves are being revolutionized. view more (2005-12-08)
Stanford researchers developing 3-D camera with 12,616 lenses
The camera you own has one main lens and produces a flat, two-dimensional photograph, whether you hold it in your hand or view it on your computer screen. On the other hand, a camera with two lenses (or two cameras placed apart from each other) can take more interesting 3-D photos. view more (2008-03-20)
Researchers create first nanofluidic transistor, the basis of future chemical processors
University of California, Berkeley, researchers have invented a variation on the standard electronic transistor, creating the first "nanofluidic" transistor that allows them to control the movement of ions through sub-microscopic, water-filled channels. view more (2005-06-30)
Study reveals new genes for excessive alcohol drinking
Researchers supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH), have identified new genes that may contribute to excessive alcohol consumption. view more (2006-04-18)
Rensselaer student invents alternative to silicon chip
Even before Weixiao Huang received his doctorate from Rensselaer Polytechnic Institute, his new transistor captured the attention of some of the biggest American and Japanese automobile companies. view more (2008-05-14)
Common algae helps illustrate mammalian brain electrical circuitry
Mice whose brain cells respond to a flash of light are providing insight into the complexities of the sense of smell and may ultimately yield a better understanding of how the human brain works. view more (2007-04-19)
New iPhone app 'Outbreaks Near Me' locates H1N1 (swine flu), infectious diseases
A new iPhone application, created by researchers at Children's Hospital Boston in collaboration with the MIT Media Lab, enables users to track and report outbreaks of infectious diseases, such as H1N1 (swine flu), on the ground in real time. view more (2009-09-02)
A new method of adult stem cell growth efficacious in treatment of disorders of the cornea
A new method of adult stem cell growth, designed in the Area of Cellular Therapy of the University Clinic (University of Navarra), has demonstrated its efficacy for its capacity to grow cornea stem cells. view more (2007-07-20)
Stimulating the appetite can lead to unrelated impulse purchases
Exposure to something that whets the appetite, such as a picture of a mouthwatering dessert, can make a person more impulsive with unrelated purchases, finds a study from the February 2008 issue of the Journal of Consumer Research. view more (2008-01-09)
Gene chips used to distinguish ventilator-associated pneumonia from underlying critical illness
Critically ill patients who need a ventilator to breathe face a high risk of pneumonia. The lung infection, however, is exceedingly difficult to diagnose because a patient's underlying condition often skews laboratory test results and masks pneumonia's symptoms - a reality that can delay appropriate antibiotic treatment. view more (2008-02-13)
Researchers: Molecular forklifts overcome obstacle to 'smart dust'
Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood. view more (2009-01-20)
Study provides hope that some transplant patients could live free of anti-rejection drugs
People with organ transplants, resigned to a lifetime of anti-rejection drugs, may now have reason to hope for a respite, say researchers at Lucile Packard Children's Hospital and the Stanford University School of Medicine. view more (2007-08-21)
Magnetic computer sensors may help study biomolecules
Magnetic switches like those in computers also might be used to manipulate individual strands of DNA for high-speed applications such as gene sequencing, experiments at the National Institute of Standards and Technology (NIST) suggest. view more (2007-05-11)
Tumor genome analysis unveils new insights into lung cancer
An international consortium of scientists today in an advanced online publication in the journal Nature revealed a comprehensive view of the altered genetic background of the type of lung cancer that is the most common cause of cancer deaths in humans. view more (2007-11-05)
LGC awarded £2m in contracts for DTI`s Measurements for Biotechnology (MfB) programme
LGC, the UK`s leading independent analytical laboratory providing chemical, biochemical and DNA analysis, has won over £2m funding in a series of eight DTI contracts spanning five themes of the Measurements for Biotechnology (MfB) programme. The two largest contracts - for improving the comparability of data generated from gene expression... view more... (2002-08-01)
ETH Zurich: Fast and Cheap Detection of Bacteria
Carbohydrates displayed on the surface of cells play critical roles in cell-cell recognition, adhesion, signaling between cells, and as markers for disease progression. Neural cells for instance use carbohydrates to facilitate development and regeneration and viruses recognize carbohydrates to gain entry into host cells. Identification of the... view more...

Scientists moving closer to 'artificial noses'
These days, chemical analysts are expected to track down even single molecules. To do this highly sensitive detective work, nano researchers have developed minute strings that resonate in characteristic fashion. view more (2009-04-23)
'Signature' of chromosome instability predicts cancer outcomes
Microscopic examination of tumor specimens cannot always predict a cancer's aggressiveness, leading to increased interest in molecular approaches to diagnosis. view more (2006-08-21)
