Physicists and geoscientists join forces in a Dutch research centre.
Luminescence dating is a new technology for the determination of the age of sediments such as sand. At the Netherlands Centre for Luminescence Dating (NCL), physicists and geoscientists join forces to use and improve this new method. The foundation of the NCL will be celebrated on Thursday 20th of March in the form of an opening symposium in the auditorium of the TNO-NITG building in Utrecht. TU Delft will act as se
By constructing artificial materials that break long-standing rules of nature, a University of Toronto researcher has developed a flat lens that could significantly enhance the resolution of imaged objects. This, in turn, could lead to smaller and more effective antennas and devices for cell phones, increased space for data storage on CD-ROMs and more complex electronic circuits.
“This is new physics,” says George Eleftheriades, a U of T professor specializing in electromagnetic technology
The human body has barriers such as skin and the lining of airways and gut that protect and separate us from the outside world. If these barriers are breached, our survival is threatened. Therefore it is critical that the cells that form these barriers have mechanisms that can instantly repair any injury.
University of Iowa researchers have discovered a surprisingly simple but effective repair system in airway barrier cells. The UI study shows that by placing a messenger molecule on one side
Howard Hughes Medical Institute researchers and their colleagues have discovered one way in which the human immunodeficiency virus (HIV) wins its cat-and-mouse game with the bodys immune system.
The study, published in the March 20, 2003, issue of the journal Nature, shows that HIV-1, a common strain of the virus that causes AIDS, uses a strategy not seen before in other viruses to escape attack by antibodies, one of the immune systems prime weapons against invading viruses and b
The delicate interplay of two chemical signals coaxes stem cells into becoming hair follicles, according to new research by scientists at the Howard Hughes Medical Institute at The Rockefeller University.
The research has implications for understanding hair growth and hair-follicle development, and it may also help explain how diverse structures, such as teeth and lungs, are formed or how some forms of skin cancer develop.

With each new vehicle, the car industry faces a fresh battle to cut out the unwanted vibrations that cause irritating rattles and the metal fatigue that can cause parts to break, with potentially lethal consequences.
The complexity of the problems persuaded the German automobile giant BMW to team up with smaller partners to find a new way of designing new vehicles. It got together with Belgian companies LMS International, a world market leader in noise and vibration engineering, optics spec
