Hybrid semiconductors show zero thermal expansion; could lead to hardier electronics and optoelectronics
The fan in your computer is there to keep the microprocessor chip from heating to the point where its component materials start to expand, inducing cracks that interrupt the flow of electricity - and not incidentally, ruin the chip. view more (2007-12-20)
Nano propellers pump with proper chemistry
The ability to pump liquids at the cellular scale opens up exciting possibilities, such as precisely targeting medicines and regulating flow into and out of cells. But designing this molecular machinery has proven difficult. view more (2007-07-17)
Finding by Rice University chemists could aid development of new nanodevices
Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures. view more (2007-03-12)
Shrinking carbon footprints
Would shrinking your carbon footprint, recycling more, and going green be easier if you could monitor your household's environmental impact? view more (2008-07-02)
Report examines hidden costs of energy production and use
A new report from the National Research Council examines and, when possible, estimates "hidden" costs of energy production and use -- such as the damage air pollution imposes on human health -- that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. view more (2009-10-20)
Nurses working extended shifts, are tired at work and sleep little likely to drive drowsy
Hospital staff nurses who work extended hours, work at night, struggle to remain awake at work, or obtain less sleep are more likely to experience a drowsy driving episode, according to a study published in the December 1 issue of the journal SLEEP. view more (2007-12-03)
NCI-Penn Collaboration Finds Targeted Immune Cells Shrink Tumors in Mice
Researchers have generated altered immune cells that are able to shrink, and in some cases eradicate, large tumors in mice. view more (2009-02-11)
Carnegie Mellon researchers urge development of low carbon electricity
Carnegie Mellon University's Constantine Samaras and Kyle Meisterling report that plug-in hybrid electric vehicles could help reduce greenhouse gas emissions that fuel global warming, but the benefits are highly dependent on how the electricity system changes in the coming decades. view more (2008-04-28)
ESA's Belgian astronaut on way to Space Station in new Soyuz spacecraft
ESA PR 68-2002. The fourth taxi flight to the International Space Station carrying a European Space Agency (ESA) astronaut and two Russian crew members made a perfect lift-off today (Wednesday, 30 October 2002) from the vast open plains of Baikonur, Kazakhstan, into the rising sun at 08:11 local time (04:11 Central European Time, 03:11 Universal... view more...

Getting the feel of virtual reality
A giant leap forward in the realism of virtual reality (VR) may be just around the corner as a team of European researchers near the completion of a pioneering project to add textures, lighting effects and 'feel' to computer-generated 3D models. view more (2005-04-27)
Ancient climate secrets raised from ocean depths
Scientists aboard the research vessel, Southern Surveyor, return to Hobart today with a collection of coral samples and photographs taken in the Southern Ocean at greater depths than ever before. view more (2008-02-04)
Nurtured chimps rake it in
Human interaction and stimulation enhance chimpanzees' cognitive abilities, according to new research from the Chimpanzee Cognition Center at The Ohio State University. view more (2007-06-14)
Lane departure warning systems help drowsy drivers avoid crashes
Four driver warning systems that may help those who fall asleep at the wheel were recently tested and evaluated by human factors/ergonomics (HF/E) researchers at Ford Motor Company. view more (2006-10-17)
NIST team proves bridge from conventional to molecular electronics possible
Researchers at the National Institute of Standards and Technology (NIST) have set the stage for building the "evolutionary link" between the microelectronics of today built from semiconductor compounds and future generations of devices made largely from complex organic molecules. view more (2008-03-19)
Technique traces origins of disease genes in mixed human populations
A team of researchers from Washington University in St. Louis and the Israeli Institute of Technology (Technion) in Haifa has developed a technique to detect the ancestry of disease genes in hybrid, or mixed, human populations. view more (2008-04-09)
Time spent in car drives up air pollution exposure
The daily commute may be taking more of a toll than people realize. A new study by researchers at the University of Southern California (USC) and the California Air Resources Board found that up to half of Los Angeles residents' total exposure to harmful air pollutants occurs while people are traveling in their vehicles. view more (2007-10-31)
Study: urban black bears 'live fast, die young'
Black bears that live around urban areas weigh more, get pregnant at a younger age, and are more likely to die violent deaths, according to a study by the Wildlife Conservation Society. view more (2008-10-01)
P2P traffic control
Could a concept from information technology familiar to online file sharers be exploited to reduce road congestion and even traffic accidents? That is the question answered in the affirmative by researchers in California, writing in the International Journal of Vehicle Information and Communication Systems. view more (2009-01-07)
Research Shows Ventilated Auto Seats Improve Fuel Economy, Comfort
The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has demonstrated that ventilated automotive seats not only can improve passenger comfort but also a vehicle's fuel economy. view more (2006-03-03)
Auto immune response creates barrier to fertility; could be a step in speciation
Plant biologists at the Max Planck Institute of Developmental Biology and the University of North Carolina at Chapel Hill have discovered that an autoimmune response, triggered by a small number of genes, can be a barrier to producing a viable offspring. view more (2007-09-04)
