Bioengineers develop a microfabricated device to measure cellular forces during tissue development
A University of Pennsylvania-collaboration of bioengineers studying the physical forces generated by individual cells has created a tiny micron-sized device that allows researchers to measure and manipulate cellular forces as assemblies of living cells reorganize themselves into tissues. view more (2009-06-23)
NJIT architect professor advocates best-building practices for high wind regions
More than ever before, building design and construction can be significantly improved to reduce wind pressures on building surfaces and to help better resist high winds and hurricanes in residential or commercial construction, said NJIT architecture professor Rima Taher, PhD. view more (2008-07-10)
Exploring the standard model of physics without the high-energy collider
Scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory in the US, have performed sophisticated laser measurements to detect the subtle effects of one of nature's most elusive forces - the "weak interaction". view more (2009-08-11)
Materials World - December 1999 Issue
3D Sound Systems Using Groundbreaking Piezoelectric Springs Digital speakers that can project three dimensional sound across a room are being developed using springs built from piezoelectric ceramics. Applying an electrical current to the material forces the spring to expand causing a vibration that produces a coherent sound image away from the... view more... (1999-11-30)
A walk along an interface yields its mobility
In the October 27th issue of Science (volume 314, page 632), researchers at Colorado School of Mines and Northeastern University report a novel computational methodology aimed at quantifying the kinetics of interfaces in diverse material systems. view more (2006-11-06)
RUBBER BULLETS NOT SAFE FOR CROWD CONTROL (p 1795)
A study in this week's issue of THE LANCET which highlights the injuries sustained by Arab demonstrators after clashes with Israeli forces in 2000 concludes that rubber bullets are not a safe form of ammunition for crowd control. Rubber bullets were first used by British forces in Northern Ireland in 1970. These missiles are intended to inflict... view more... (2002-05-22)
Researchers make nanosheets that mimic protein formation
University of Michigan researchers have discovered a way to make nanocrystals in a fluid assemble into free-floating sheets the same way some protein structures form in living organisms. view more (2006-10-13)
New molecular force probe stretches molecules, atom by atom
Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed. view more (2009-03-30)
Caught In The Act - Scientists Develop Thinking CCTV Cameras
The University of Surrey's scientists have been given half a million pounds to develop close circuit television cameras that will 'think' for themselves, alerting police to crimes in our city centres. The joint project between academics and the police will program computers to spot criminals whilst they are right in the middle of a crime. For... view more... (2004-06-18)
Supercomputer simulations shed light on cataclysmic variable flashes.
New supercomputer simulations may help explain periodic bursts of light emitted by compact binary star systems. view more (2005-03-31)
U of T team heats up gold to surprising effect: it gets harder not softer
Common sense tells us that when you heat something up it gets softer, but a team of researchers, led by University of Toronto chemistry and physics professor R.J. Dwayne Miller, has demonstrated the exact opposite. view more (2009-01-23)
How movement lubricates bone joints
Taking a cue from machines that gently flex patients' knees to help them recover faster from joint surgery, bioengineering researchers at UC San Diego have shown that sliding forces applied to cartilage surfaces prompt cells in that tissue to produce molecules that lubricate and protect joints. view more (2006-12-05)
Expert says nanotechnology should look to Mother Nature
Professor Richard Jones of the University of Sheffield has today outlined the possibilities of using nature's secrets to develop nanotechnology, and casts doubt on some popular assumptions about the science, including the premise that we may create nano-robots with the power to reduce the world to 'grey goo'. Professor Jones is internationally... view more... (2004-08-11)
NASA scientists report on new technology to help protect US troops from infectious diseases
Representatives from NASA convened in New Orleans today to report at the American Society of Tropical Medicine and Hygiene Annual Meeting the results from a NASA-enhanced computerized system to assess environmental and health concerns for deployed U.S. forces. view more (2008-12-11)
What caused westward expansion in the United States?
Western Expansion during the nineteenth century was an important determinant of geographic distribution and economic activity in the United States today. However, while explanations abound for why the migration occurred- from the low price of land to a pioneering spirit - little empirical work has been done to determine which specific market... view more...

Researchers identify proteins making up mechanosensitive ion channels
Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery. view more (2008-06-03)
ESA to look for the missing link in gravity
Although you can never be certain of predicting future developments in science, there is a good chance of a fundamental breakthrough in physics soon. With a series of unique experiments and missions designed to test our understanding of gravity, the European Space Agency (ESA) hopes to get to the very bottom of it. Scientists will study space... view more... (2002-09-11)
New definition could further limit habitable zones around distant suns
As astronomers gaze toward nearby planetary systems in search of life, they are focusing their attention on each system's habitable zone, where heat radiated from the star is just right to keep a planet's water in liquid form. view more (2009-06-11)
Scientists find new way to manipulate DNA
Polymers, large molecules comprised of chains of repeating structures, are used in everything from the coatings on walls of ships and pipes to reduce flow drag to gene therapy. view more (2006-11-16)
NIST develops novel ion trap for sensing force and light
Miniature devices for trapping ions (electrically charged atoms) are common components in atomic clocks and quantum computing research. Now, a novel ion trap geometry demonstrated at the National Institute of Standards and Technology (NIST) could usher in a new generation of applications because the device holds promise as a stylus for sensing... view more...
