Smallest Nanoantennas for High-speed Data Networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. view more (2009-10-21)
EARLY CASE OF RESISTANCE TO NEW ANTIBIOTIC (p 207)
A fast-track research letter published in this week’s issue of THE LANCET describes the case of a patient whose infecting bacterium developed resistance to one of the new so-called bug-busting antibiotics. Multidrug resistant bacteria have caused enormous difficulties worldwide over the past few decades. Scientists had hoped, however, that... view more... (2001-07-18)
MIT replaces chrome coatings with safer metal alloys
Ever since the 1940s, chrome has been used to add a protective coating and shiny luster to a wide range of metal products, from bathroom fixtures to car bumpers. view more (2009-05-21)
Large-Scale Tonsillectomy Would Quantify UK CJD Prevalence (pp 1196, 1260)
A study in this week's issue of THE LANCET describes how two different types of analysis used in conjunction on samples of tonsil tissue is the 'gold standard' method for confirming clinical variant CJD, and that a large-scale screening programme of tonsil tissue is the only way of identifying the true incidence of vCJD infection. view more (2004-09-29)
DOE JGI sets 'gold standard' for metagenomic data analysis
With the advent of more powerful and economical DNA sequencing technologies, gene discovery and characterization is transitioning from single-organism studies to revealing the potential biotechnology applications embedded in communities of microbial genomes, or metagenomes. view more (2007-05-15)
Biosensing nanodevice to revolutionize health screenings
One day soon a biosensing nanodevice developed by Arizona State University researcher Wayne Frasch may eliminate long lines at airport security checkpoints and revolutionize health screenings for diseases like anthrax, cancer and antibiotic resistant Staphylococcus aureus (MRSA). view more (2008-03-25)
The mysterious case of Columbus's silver ore
Silver-bearing ore found at the settlement founded by Christopher Columbus's second expedition was not mined in the Americas, new research reveals. view more (2007-02-20)
Nanocups brim with potential
Researchers at Rice University have created a metamaterial that could light the way toward high-powered optics, ultra-efficient solar cells and even cloaking devices. view more (2009-03-16)
Gold nanoparticles could improve antisense cancer drugs
In the fight against cancer, antisense drugs, which prevent genes from producing harmful proteins such as those that cause cancer, have the promise to be more effective than conventional drugs, but the pace of development of these new drugs has been slow. view more (2006-05-19)
MIT researchers build tiny batteries with viruses
MIT scientists have harnessed the construction talents of tiny viruses to build ultra-small "nanowire" structures for use in very thin lithium-ion batteries. view more (2006-04-07)
Fiber-based nanotechnology in clothing could harvest energy from physical movement
Nanotechnology researchers are developing the perfect complement to the power tie: a "power shirt" able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical motion could be harnessed and converted to electrical energy. view more (2008-02-14)
Syracuse University researchers build new surface material that resists biofilm growth; new technology may lead to development of improved medical implants
This is the tale of two biological substances-cells from mammals and bacteria. It's a story about the havoc these microscopic entities can wreak on all manner of surfaces, from mighty ships to teeth and medical devices, and how two Syracuse University researchers are discovering new ways to prevent the damage. view more (2009-03-20)
AGI reports on the price of oil and the US dollar
The American Geological Institute Workforce Program has released its latest data report, this time looking at the price of crude oil and the exchange rate of the U.S. dollar. view more (2008-04-16)
Like sweets? You're more like a fruit fly than you think...
According to researchers at the Monell Center, fruit flies are more like humans in their responses to many sweet tastes than are almost any other species. view more (2008-03-18)
Lab-on-a-Chip Homes in on How Cancer Cells Break Free
Johns Hopkins engineers have invented a method that could be used to help figure out how cancer cells break free from neighboring tissue, an "escape" that can spread the disease to other parts of the body. view more (2009-03-19)
Nanoneedle is small in size, but huge in applications
Researchers at the University of Illinois have developed a membrane-penetrating nanoneedle for the targeted delivery of one or more molecules into the cytoplasm or the nucleus of living cells. view more (2009-04-29)
Are tougher electronic components on the way?
Like modern day alchemists, materials scientists often turn unassuming substances into desirable ones. But instead of working metal into gold, they create strange new compounds that could make the electronic components of the future smaller, faster, and more durable. view more (2006-03-09)
Supercomputer could throw light on 'mysterious' dark energy
Cosmologists have run a series of huge computer simulations of the Universe that could ultimately help solve the mystery of dark energy. view more (2008-01-11)
New test can rule out heart damage within six hours
A new test to assess chest pain in UK emergency departments can rule out the possibility of heart damage within six hours, allowing safe discharge of patients and reducing unnecessary admissions, finds a study in this week's BMJ. The current approach requires admission to hospital for a minimum of 24 hours. Over a 12-month period, researchers at... view more... (2001-08-15)
UK Study Finds Meal Replacements Aid Weight Loss
Meal replacements in a medically supervised weight loss program are successful in facilitating weight loss, according to a new study conducted at the University of Kentucky. view more (2009-08-13)
