University of Toronto chemists uncover green catalysts
A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavours. view more (2009-04-14)
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)
Penguins marching into trouble
A quarter-century of data reveals how changing weather patterns and land use, combined with overfishing and pollution, are taking a heavy toll on penguin numbers view more (2009-02-13)
A double-threat to teen health
As teens head back to school, health teachers may want to revise their lesson plans. Temple researchers have found that kids who engage in heavy drinking will more than likely also engage in heavy smoking, and they say educators can help combat the trend by addressing both topics as one health risk. view more (2009-08-10)
New petroleum-degrading bacteria found at Rancho La Brea Tar Pits in Los Angeles
Environmental scientists at UC Riverside have discovered that the Rancho La Brea tar pits in downtown Los Angeles, Calif., house hundreds of new species of bacteria with unusual properties, allowing the bacteria to survive and grow in heavy oil and natural asphalt. view more (2007-05-11)
Plastics that resemble PVC - without chlorine
Even non-chemists know at least the abbreviations of those nasty substances: DDT is a highly persistent insecticide, CFCs used as propellants and refrigerants destroy atmospheric ozone, and PVC stands for plastics often regarded with suspicion. Add PCBs and PCP to this cocktail, and you can't help wondering why industry doesn't simply stop using... view more... (2003-05-22)
Metal deformation studies lead to new understanding of materials at extreme conditions
By combining very large-scale molecular dynamics simulations with time-resolved data from laser experiments of shock wave propagation through specific metals, scientists at the Lawrence Livermore National Laboratory are now able to better understand the evolution of high-strain-rate plasticity. view more (2006-09-19)
Cockles and mussels reveal all
Cockles and mussels harvested on the shores of the Irish Sea may have provided a staple diet for Molly Malone and her fellow Dubliners, but for scientists at the University of Wales, Aberystwyth they are, along with longer living species such as the clam Arctica islandica*, a detailed record of pollution extending back over two centuries. The... view more... (2004-04-01)
New study shows link between heavy drinking and atrial fibrillation
A large-scale study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) has found that heavy alcohol consumption - 35 or more drinks per week - can significantly increase men's risk of developing atrial fibrillation, a dangerous type of arrhythmia and one of the leading risk factors for stroke. view more (2005-09-13)
Delta II Rocket Coming Together for NASA's GLAST Satellite Launch
The Delta II 7920-H, or "Heavy," rocket that will launch NASA's Gamma-ray Large Area Telescope (GLAST) satellite is in the process of being assembled on Launch Pad 17-B at Cape Canaveral Air Force Station, Fla. view more (2008-04-15)
Old gastrointestinal drug slows aging, McGill researchers say
Recent animal studies have shown that clioquinol - an 80-year old drug once used to treat diarrhea and other gastrointestinal disorders - can reverse the progression of Alzheimer's, Parkinson's and Huntington's diseases. view more (2009-01-07)
Scientific innovation on display at the Royal Show (5-8 July)
There are features on: view more (1999-06-30)
UCLA, Italian chemists move closer to solving Lou Gehrig's disease mystery
Chemists from UCLA and the University of Florence in Italy may have solved an important mystery about a protein that plays a key role in a particular form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, a progressive, fatal neurodegenerative disorder that strikes without warning. view more (2007-06-28)
Hybrid coatings increase hardness of plastic and allow properties to be tailored
Increasing the surface hardness of many materials opens them up for use in a wide variety of new applications. These new hybrid materials could be used in areas like anticorrosion coatings for metals, scratch and abrasion resistant coatings for plastics, antistatic films plus colour decorative coatings for glasses and plastics. view more (2006-05-15)
College drinking problems, deaths on the rise
Alcohol-related deaths, heavy drinking episodes and drunk driving have all been on the rise on college campuses over the past decade, a new government study shows. view more (2009-06-15)
Heavy-drinking colleges showing no improvements
U.S. colleges with the biggest student drinking problems have so far failed to turn the tide, according to a new study. view more (2009-09-11)
Laser trapping of erbium may lead to novel devices
Physicists at the National Institute of Standards and Technology (NIST) have used lasers to cool and trap erbium atoms, a "rare earth" heavy metal with unusual optical, electronic and magnetic properties. view more (2006-05-01)
Waste water treatment plant mud used as 'green' fuel
Catalan scientists have shown that using mud from waste water treatment plants as a partial alternative fuel can enable cement factories to reduce their CO2 emissions and comply with the Kyoto Protocol, as well as posing no risk to human health and being profitable. view more (2009-06-24)
UCR chemists prepare molecules that accelerate chemical reactions for manufacturing drugs
Chemists at the University of California, Riverside have synthesized a new class of carbenes - molecules that have unusual carbon atoms - that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs. view more (2005-08-22)
Massive Black Hole Smashes Record
Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star. The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star. view more (2007-10-31)
