Shallow water yields deep research results
Donald Rockwell's research team has developed imaging techniques to study flow patterns and vortices in shallow bodies of water.
The ice chasers
Nearly a century after crewman Frederick Fleet clanged the warning bell and yelled "Iceberg, straight ahead!" much too late from the crow's nest of the doomed Titanic, navigation in so-called "Iceberg Alley" along the Grand Banks southeast of Newfoundland remains fraught with the constant threat of collision with a massive, drifting monolith of ice.
From silicon to the sea: managing heat aboard modern ships
With a major grant from the Office of Naval Affairs, researchers at Rensselaer Polytechnic Institute are collaborating with four other universities to address a hot topic in today's military: how to keep modern ships cool in extreme environments.
Engineers set new world record in generation of high-frequency submillimeter waves
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have achieved a new world record in high-frequency submillimeter waves. The record-setting 324-gigahertz frequency was accomplished using a voltage-controlled oscillator in a 90-nanometer complementary metal-oxide semiconductor (CMOS) integrated circuit, a technology used in chips such as microprocessors.
Tsunami wave simulator
Using a serendipitous $100,000 grant, Philip Liu, Cornell professor of civil and environmental engineering, will upgrade a wave simulator that is helping predict the effects of tsunamis on buildings and may contribute to the development of improved early warning systems.
Electronic displays that fit on clothing could power revolution in lighting
A thin film of plastic which conducts electricity and produces solar power could be the basis for a revolution in the way we light our homes and design clothes.
3d solar cells boost efficiency, reduce size
Unique three-dimensional solar cells that capture nearly all of the light that strikes them could boost the efficiency of photovoltaic (PV) systems while reducing their size, weight and mechanical complexity.
Spintronic devices
An interdisciplinary group of scientists at the U.S. Department of Energy's Brookhaven National Laboratory has devised methods to make a new class of electronic devices based on a property of electrons known as "spin," rather than merely their electric charge. This approach, dubbed spintronics, could open the way to increasing dramatically the productivity of electronic devices operating at the nanoscale — on the order of billionths of a meter.
Carnegie mellon unveils internet-controlled robots that anyone can build by following the right recipe
Carnegie Mellon University researchers have developed a new series of robots that are simple enough for almost anyone to build with off-the-shelf parts, but are sophisticated machines that wirelessly connect to the Internet.
New mit technique weighs single living cells
For the first time, MIT researchers have found a way to measure the mass of single cells with high accuracy.

Why nanowires make great photodetectors
The geometry of semiconducting nanowires makes them uniquely suited for light detection, according to a new UC San Diego study that highlights the possibility of nanowire light detectors with single-photon sensitivity.
The fastest industrial robot on the market
Researchers from CNRS and the Spanish foundation Fatronik have designed a manipulator-type robot that is twice as fast as all existing robots. To achieve this feat, which has not gone unnoticed by industry, they have worked on optimizing both the shape of the robot and its control system. The robot, baptized Adept Quattro from the name of its manufacturer and because of its four arms, has just been launched on the market. Several hundred orders have already been placed, among others, by the food processing, health and beauty industries.
Rapid-fire pulse brings Sandia Z method closer to goal of high-yield fusion reactor
An electrical circuit that should carry enough power to produce the long-sought goal of controlled high-yield nuclear fusion and, equally important, do it every 10 seconds, has undergone extensive preliminary experiments and computer simulations at Sandia National Laboratories' Z machine facility.
IBM brings nature to computer chip manufacturing
IBM announced the first-ever application of a breakthrough self-assembling nanotechnology to conventional chip manufacturing, borrowing a process from nature to build the next generation computer chips.
Student designer and fiber scientists create a dress that prevents colds and a jacket that destroys noxious gases
Fashion designers and fiber scientists at Cornell have taken "functional clothing" to a whole new level. They have designed a garment that can prevent colds and flu and never needs washing, and another that destroys harmful gases and protects the wearer from smog and air pollution.
Quantum dot recipe may lead to cheaper solar panels
Rice University scientists recently revealed a breakthrough method for producing molecular specks of semiconductors called quantum dots, a discovery that could clear the way for better, cheaper solar energy panels.
New nanocomposite process improves capacitors
A new technique for creating films of barium titanate (BaTiO3) nanoparticles in a polymer matrix could allow fabrication of improved capacitors able to store twice as much energy as conventional devices. The improved capacitors could be used in consumer devices such as cellular telephones – and in defense applications requiring both high energy storage and rapid current discharge.
Revolutionizing prosthetics 2009 team delivers first darpa limb prototype
An international team led by the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., has developed a prototype of the first fully integrated prosthetic arm that can be controlled naturally, provide sensory feedback and allows for eight degrees of freedom—a level of control far beyond the current state of the art for prosthetic limbs.
Low-energy lighting project is streets ahead
Technology that first appeared in digital watches and calculators back in the 1970s is being used to develop durable and community-friendly low energy street lighting. Researchers at The University of Manchester have joined forces with Dialight Lumidrives - founded by a successful former student - to develop powerful low-cost LED lighting modules that can be used in buildings and on roads.
Nanotechnology may be used to regenerate tissues, organs
Research at Northwestern University has shown that a combination of nanotechnology and biology may enable damaged tissues and organs to heal themselves.

| Quotes | Ive always wanted to be a scientist. That way, I could get a bunch of grants and do research into whether money can really buy happiness.
Kyannke.
Ive always wanted to be somebody, but I see now I should have been more specific.
