Cancer researchers at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have found that zinc treatment may help prevent esophageal and oral cancers in those individuals at high risk.
Oral and esophageal cancers are associated with nutritional zinc deficiency, and a rise in the expression of the enzyme COX-2 is connected with these cancers. Louise Fong, Ph.D., assistant professor of microbiology and immunology at Jefferson Medical College of Thomas Jefferson University, and her co-workers have found that zinc given orally to zinc-deficient rats reverses the development of precancerous conditions in the esophagus and tongue and reverses the high expression of COX-2 there as well.
These findings suggest that zinc supplements may prevent the development of esophageal or oral cancers, particularly in developing countries where zinc deficiency is a problem. The researchers reported their findings January 5, 2005 in the Journal of the National Cancer Institute. Zinc in the diet comes mostly from red meat and seafood. Whereas up to 10 percent of Americans have a zinc-deficient diet, as many as 2 billion individuals in developing countries are zinc-deficient. Epidemiological evidence show the incidence of esophageal and oral cancers is rising in recent years. As many as 13,000 Americans die from esophageal cancer each year.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
