A giant step toward infinitesimal machinery
What are the ultimate limits to miniaturization? How small can machinery--with internal workings that move, turn, and vibrate--be produced? What is the smallest scale on which computers can be built? With uncanny and characteristic insight, these are questions that the legendary Caltech physicist Richard Feynman asked himself in the period leading up to a famous 1959 lecture, the first on a topic now called nanotechnology.
New device a lifesaver for divers
Technology traditionally used to communicate with underwater vehicles is now destined to help divers in distress.
Google meets Sherlock Holmes
Soon after 9-11, Americans wondered aloud: How did our guardians miss the clues? Suspects on watch lists had moved money in curious ways. "Chatter" had risen in recent months. A visitor to the country had offered cash to learn how to fly—but not land—a jetliner. In hindsight, these telltale nuggets provided evidence of the terror to come.
Certain home shapes and roofs hold up best in hurricane
A few days ago, the remnants of Hurricane Noel traveled northward to New York and New England with wind speeds approaching 80 miles per hour in Massachusetts. The storm caused significant damages, especially there.
Researchers double cell phone memory through software alone
Cell phones are increasingly sophisticated -- sporting such features as cameras, music players, games, video clips, Internet access and, lest we forget, the capability to phone someone -- but these features come at a price: memory.
Researchers push transmission rate of copper cable
You may not be able to get blood out of a turnip, but according to Penn State engineers, you can increase the data transmission of Category-7 copper cables used to connect computers to each other and the Internet.
Mit's 'electronic nose' could detect hazards
A tiny "electronic nose" that MIT researchers have engineered with a novel inkjet printing method could be used to detect hazards including carbon monoxide, harmful industrial solvents and explosives.
Nuclear desalination
New solutions to the ancient problem of maintaining a fresh water supply is discussed in a special issue of the Inderscience publication International Journal of Nuclear Desalination. With predictions that more than 3.5 billion people will live in areas facing severe water shortages by the year 2025, the challenge is to find an environmentally benign way to remove salt from seawater.
Fed-tvs with carbon nanotube technology could supersede plasma and LCD flat screens
Just as silicon is the wonder material for the computer age, carbon nanotubes will most likely be the materials responsible for the next evolutionary step in electronics and computing. Their extraordinary properties have identified them as having the potential to revolutionise many technologies.
Wind farms power source
Wind power, long considered to be as fickle as wind itself, can be groomed to become a steady, dependable source of electricity and delivered at a lower cost than at present, according to scientists at Stanford University.

Bee strategy helps servers run more sweetly
Honeybees somehow manage to efficiently collect a lot of nectar with limited resources and no central command — after all, the queen bee is too busy laying eggs to oversee something as mundane as where the best nectar can be found on any given morning. According to new research from the Georgia Institute of Technology, the swarm intelligence of these amazingly organized bees can also be used to improve the efficiency of Internet servers faced with similar challenges.
Engineering project explores energy conservation through shark research
The stars of the "Jaws" films–sharks–have recently become the subject of a University of Alabama engineering research project. Conducted by Dr. Amy Lang, assistant professor of aerospace engineering and mechanics, the project explores energy conservation and boundary layer control in regard to a shark's surface.
New T-Ray source could improve airport security, cancer detection
Going through airport security can be such a hassle. Shoes, laptops, toothpastes, watches and belts all get taken off, taken out, scanned, examined, handled and repacked. But "T-rays", a completely safe form of electromagnetic radiation, may reshape not only airport screening procedures but also medical imaging practices.
Smarter energy storage for solar and wind power
Development of the first hybrid battery suitable for storing electricity from renewable energy sources such as solar and wind is now a step closer.
UCLA mathematician works to make virtual surgery a reality
A surgeon accidently kills a patient, undoes the error and starts over again. Can mathematics make such science fiction a reality?
Cuter scooter defined by electricity, portability
It's energy efficient, it's clean, compact and simple, and, above all, it's very cool.
Research breakthrough uses nanotechnology to target cancer tumors
An Oregon State University-led research team has successfully used nanotechnology to deliver diagnostic imaging agents to cancerous tumors. The specially designed "peptide" – or compound comprised of amino acids – attaches directly to cancer cells in animals by targeting the tumors' low pH levels.
V2g car generates electricity, and cash
The price of oil nearly reached $100 a barrel recently, but a new University of Delaware prototype vehicle demonstrates how the cost of the black stuff could become a concern of the past.
High-tech helmets reveal new information about the impact of hard hits to the head
In a game that spawned the term "slobber knocker," is there a limit to the amount of impact a football player's head can handle before the player suffers a concussion?
Sandias sunshine to petrol project seeks fuel from thin air
Using concentrated solar energy to reverse combustion, a research team from Sandia National Laboratories is building a prototype device intended to chemically "reenergize" carbon dioxide into carbon monoxide using concentrated solar power. The carbon monoxide could then be used to make hydrogen or serve as a building block to synthesize a liquid combustible fuel, such as methanol or even gasoline, diesel and jet fuel.
