MIT engineers probe spiders' polymer art
A team of MIT engineers has identified two key physical processes that lend spider silk its unrivaled strength and durability, bringing closer to reality the long-sought goal of spinning artificial spider silk. view more (2006-10-31)
Teachers present 'Food for Life - Physics of Food' at international festival
Food is vital for life, and it's also vital for teaching physics. The presentation 'Food for Life - Physics of Food', was given by a British team at the European festival Physics on Stage 3 on Wednesday 12 November, in Noordwijk, The Netherlands. Physics on Stage 3 was a festival which gave physicists, teachers and science communicators a unique... view more... (2003-11-13)
Surface tension drives segregation within cell mixtures
What does a mixture of two different kinds of cells have in common with a mixture of oil and water? The same basic force causes both mixtures to separate into two distinct regions. view more (2008-10-07)
Engineers demonstrate a new type of optical tweezer
Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) demonstrated a new type of optical tweezer with the potential to make biological and microfluidic force measurements in integrated systems such as microfluidic chips. view more (2008-02-26)
Solving the mystery of the Tibetan Plateau
A University of Alberta physicist who helped solve the age-old mystery of what keeps afloat the highest plateau on earth has added more pieces to the Tibetan puzzle. Dr. Martyn Unsworth has uncovered new research about the Tibetan Plateau-an immense region that for years has plagued scientists studying how the area became so elevated. view more (2005-11-04)
Measuring the smallest particles
When someone says: "Everything flows - nothing stays the same", he seldomly refers to toothpaste, ointment or paint. However, manufacturers are immensely interested in the way in which such products "flow" in daily use. For example, wall paint should be thin in consistency, easy to work with and still adhere to walls after application. The amount... view more... (2001-06-25)
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)
Researchers help sort out the carbon nanotube problem
National Institute of Standards and Technology (NIST) and university researchers report a significant step toward sorting out the nanotube "problem"-the challenge of overcoming processing obstacles so that the remarkable properties of the tiny cylindrical structures can be exploited in new polymer composite materials of exceptional... view more...

External Magnetic Field Causes The Puzzling Heating Of The Solar Corona
The Russian astrophysicists have theoretically modelled coronal loop oscillations and have shown that the plasma present in coronal loops is quite "normal". So, the puzzle of the Sun`s atmosphere heating remains unresolved. Coronal loops, immense magnetic arches more hot and dense than the coronal... view more... (2002-06-21)
On chip separation: large molecules pass the speed camera first
What molecule or particle passes the finishline first? A good way to split a fluid sample into its separate parts is: organize a contest in a micro-channel. The largest parts will pass the optical detector first, the smaller ones follow at short distance. This principle of 'hydrodynamic chromatography' is now also possible on a chip. 'On-chip'... view more... (2002-12-10)
Ancient volcanic eruptions caused global mass extinction
A previously unknown giant volcanic eruption that led to global mass extinction 260million years ago has been uncovered by scientists at the University of Leeds. view more (2009-05-29)
Researcher examines polymers created with poultry feathers
Biodegradable polymers created from poultry feathers may add value to the poultry industry and help solve the growing environmental problem of plastic waste. view more (2007-03-30)
New nanochemistry technique encases single molecules in microdroplets
Inventing a useful new tool for creating chemical reactions between single molecules, scientists at the National Institute of Standards and Technology (NIST) have employed microfluidics-the manipulation of fluids at the microscopic scale-to make microdroplets that contain single molecules of interest. view more (2009-09-23)
Simple device which uses electrical field could boost gas efficiency
With the high cost of gasoline and diesel fuel impacting costs for automobiles, trucks, buses and the overall economy, a Temple University physics professor has developed a simple device which could dramatically improve fuel efficiency as much as 20 percent. view more (2008-09-26)
Coal-based jet fuel poised for next step
A jet fuel comparable to Jet A or military JP 8, but derived from at least 50 percent bituminous coal, has successfully powered a helicopter jet engine, according to a Penn State fuel scientist. view more (2006-03-28)
Slippery customer: A greener antiwear additive for engine oils
Titanium, a protean element with applications from pigments to aerospace alloys, could get a new role as an environmentally friendly additive for automotive oil, thanks to work by materials scientists from Afton Chemical Corporation (Richmond, Va.) and the National Institute of Standards and Technology (NIST). view more (2008-07-24)
Green industrial lubricant developed
A team of researchers from the University of Huelva has developed an environmentally-friendly lubricating grease based on ricin oil and cellulose derivatives, according to the journal Green Chemistry. view more (2009-07-13)
Videos extract mechanical properties of liquid-gel interfaces
Blood coursing through vessels, lubricated cartilage sliding against joints, ink jets splashing on paper-living and nonliving things abound with fluids meeting solids. view more (2008-01-24)
New designer lipid-like peptide with lipid nanostructures for drug delivery systems
Scientists from Institute of Biophysics and Nanosystems Research (IBN), Austrian Academy of Sciences and of Centre for Biomedical Engineering, Massachusetts Institute of Technology, Cambridge, USA report the study of "Tuning Curvature and Stability of Monoolein Bilayers by Designer Lipid-Like Peptide Surfactants" in the May 30th issue of... view more...
