Creating better automotive components
Car manufacture uses a wide range of different materials. Among the metals, steels lead the way followed by aluminum and - to an increasing extent - magnesium. With the latter the argument of reduced weight and therefore lower fuel consumption is a very popular one. But the real issue is about availability and price, along with the production... view more... (2002-07-22)
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)
Aggressive microdermabrasion induces wound-healing response in aging skin
Microdermabrasion using a coarse diamond-studded instrument appears to induce molecular changes in the skin of older adults that mimic the way skin is remodeled during the wound healing process. view more (2009-10-20)
Hammering sheet metal into shape
The tool at the pressing plant resonantly pounds the sheet metal, ejecting the newly formed vehicle hood moments later. Although this operation runs like clockwork on the production line, it caused the developers of the metal-forming equipment many a headache, since sheet metal springs back (unbends elastically) when the press is opened. The... view more... (2003-02-20)
Researchers examine why food tastes bad to chemotherapy recipients
About two million cancer patients currently receiving certain drug therapies and chemotherapy find foods and beverages to have a foul metallic flavor. view more (2006-09-20)
Pressure to get in shape
Electric windows, air-conditioning, ABS braking and airbags have become standard features in most vehicles. But while electronic components increase the safety and comfort of cars, they also make them heavier; and the greater a car's weight, the higher its fuel consumption. One solution is to shed weight. Since few motorists are nowadays willing... view more... (2002-12-20)
The Semiconductor Devices of the Future
When physicists sandwiched together different types of semiconductor to create the first transistor in 1947, they made bulky vacuum valves obsolete and so revolutionised the electronics industry. Since then researchers have been pushing the boundaries of semiconductor technology hoping for another revolution. At the 26th International Conference... view more... (2002-07-23)
Mirror Measures Vortex Drag
Airplanes generate trailing wake vortices which can be dangerous for following aircraft, especially on takeoff and landing. An onboard laser measuring device scans the air space in front of the plane, recognizes turbulence and will inform the pilot. The volume of air traffic is constantly rising - many air routes are already overloaded. Frequent... view more... (2004-07-08)
Superconductivity can induce magnetism
When an electrical current passes through a wire it emanates heat - a principle that's found in toasters and incandescent light bulbs. view more (2008-09-12)
New technology has dramatic chip-cooling potential for future computers
Researchers have demonstrated a new technology using tiny "ionic wind engines" that might dramatically improve computer chip cooling, possibly addressing a looming threat to future advances in computers and electronics. view more (2007-08-14)
Hot peppers really do bring the heat
Chili peppers can do more than just make you feel hot, reports a study in the August 1 Journal of Biological Chemistry; the active chemical in peppers can directly induce thermogenesis, the process by which cells convert energy into heat. view more (2008-08-07)
Bio-imaging mass spectrometry techniques reveal molecular details about complex systems
Understanding biology at the systems level is difficult, especially when studying complex specimens like tissue slices or communities of organisms in a biofilm. Scientists must be able to identify, quantify and locate the molecules present in the samples. view more (2008-09-26)
Tiny ion pump sets new standard in cooling hot computer chips
University of Washington researchers have succeeded in building a cooling device tiny enough to fit on a computer chip that could work reliably and efficiently with the smallest microelectronic components. view more (2006-08-24)
Popular Arthritis Drug May Disrupt Heart Rhythm, UB Research Finds
Celebrex, a popular arthritis drug that blocks pain by inhibiting an enzyme known as COX-2, has been shown in laboratory studies to induce arrhythmia, or irregular beating of the heart, via a novel pathway unrelated to its COX-2 inhibition. view more (2008-01-25)
Brain power goes green
Our brains, it turns out, are eco-friendly. A study published in Science and reviewed by F1000 Biology members Venkatesh Murthy and Jakob Sorensen reveals that our brains have the amazing ability to be energy efficient. view more (2009-10-15)
NASA's Swift Looks to Comets for a Cool View
NASA's Swift Gamma-ray Explorer satellite rocketed into space in 2004 on a mission to study some of the highest-energy events in the universe. view more (2008-12-04)
Nanowires May Lead To Better Fuel Cells
The creation of long platinum nanowires at the University of Rochester could soon lead to the development of commercially viable fuel cells. view more (2009-03-12)
Really Hot Stars
Spectacular VLT Photos Unveil Mysterious Nebulae Quite a few of the most beautiful objects in the Universe are still shrouded in mystery. Even though most of the nebulae of gas and dust in our vicinity are now rather well understood, there are some which continue to puzzle astronomers. This is the case of a small number of unusual nebulae that... view more... (2003-04-09)
IBEX discovers that galactic magnetic fields may control the boundaries of our solar system
The first all-sky maps developed by NASA's Interstellar Boundary Explorer (IBEX) spacecraft, the initial mission to examine the global interactions occurring at the edge of the solar system, suggest that the galactic magnetic fields had a far greater impact on Earth's history than previously conceived, and the future of our planet and others may... view more...

Clemson chemists discover new way antioxidants fight debilitating diseases
Cancer, cardiovascular diseases, Parkinson's and Alzheimer's are often linked to DNA damage that occurs when metal ions in the body such as iron and copper produce reactive oxygen compounds that damage human cells. view more (2007-08-20)
