Luminescence Dating, a new method of age determination

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

Study shows lightning adds to ozone level

Lightning may be Mother Nature’s greatest show on Earth, but scientists now know it can produce significant amounts of ozone and other gases that affect air chemistry.

Researcher Renyi Zhang of Texas A&M University helped lead a study on the impact of lightning, and the results are surprising: Lightning can be responsible for as much as 90 percent of the nitrogen oxides in the summer and at the same time increase ozone levels as much as 30 percent in the free troposphere, the area that

Receptor found that guides nerve cells to their final connecting sites

In the developing brain, nerve cells make connections with one another by extending processes, often over long distances.

The growing tips of these nerve cell processes are guided to their ultimate connection sites by molecular cues in the environment.

A Salk Institute research team has discovered a receptor-protein interaction that guides nerve cells along specific pathways.

John Thomas, professor of molecular neurobiology, working on the fruit fly Drosophila, found tha

University of Toronto study charts new realm of physics

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

Underwater sensor system could protect reservoirs, drinking water

A sensor system that can autonomously, continuously and in real-time monitor streams, lakes, ocean bays and other bodies of liquid may help solve problems for environmentalists, manufacturers and those in charge of homeland security, according to Penn State engineers.

“The importance of developing a network sensor technology for operation in liquid environments has recently been highlighted in reports detailing the chemical slurry of antibiotics, estrogen-type hormones, insecticides, nicotin

Researchers Identify Signals that Cause Hair Follicles to Sprout

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.

In an article published in the March 20, 2003, issue of the
