For the approximately 30 percent of the U.S. population affected by venous disease, covering up their varicose and spider veins with clothing or cosmetics can be a real pain. But the physical pain caused by this common medical condition is what drives most patients to seek treatment.
Speaking at ACADEMY ’04, the American Academy of Dermatology’s summer scientific session in New York, dermatologist Mitchel P. Goldman, M.D., an associate clinical professor of dermatology at the University of California, San Diego, discussed the latest minimally invasive treatment options available for patients with varicose and spider veins.
Varicose veins are abnormally swollen or enlarged blood vessels caused by a weakening in the vein’s wall, which often leads to pain and swelling in the leg. Varicose veins occur from the backward flow of blood in the legs caused by damaged or diseased valves in the veins. Spider veins, on the other hand, are dilated small blood vessels located close to the surface of the skin that have a red or bluish color. Although they can appear anywhere on the body, spider veins typically occur on the legs and face.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion
Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
