A new study finds tobacco may act as an environmental trigger for patients with an inherited genetic predisposition to pancreatic cancer. The authors of the report say the findings underscore the importance of strongly counseling patients with a family history of pancreatic cancer to avoid smoking. The study will be published in the December 15, 2004 issue of CANCER, a peer-reviewed journal of the American Cancer Society. A free abstract of this study will be available via the CANCER News Room upon online publication.
Pancreatic cancer is rare and poorly studied. What is known is that pancreatic cancer is aggressive, with a five-year survival rate of only 4 percent. A small percentage of patients with pancreatic cancer have first-degree relatives with pancreatic cancer. Smoking has been identified as the single most important risk factor in familial pancreatic cancer. Despite genetic characterization of other hereditary cancers, the genetic component of pancreatic cancer remains a mystery. With such little known about what is now called familial pancreatic adenocarcinoma (FPAC), researchers led by Ted A. James, M.D. of the Roswell Park Cancer Institute in Buffalo, New York investigated the clinical course and outcome of FPAC compared to sporadic pancreatic cancer.
Retrospective review of 826 patients with pancreatic cancer found 30 had the familial form (3.6 percent). Earlier age at diagnosis and a smoking history were marked features among the familial group. The mean age of diagnosis was younger in the hereditary cohort than among those with the sporadic form (57.1 years old versus 61 years old), and more FPAC patients were diagnosed before the age of 50 (36.7 percent versus 18.3 percent). Moreover, patients with FPAC were more likely to smoke than those who had sporadic pancreatic cancer (87 percent versus 66 percent).

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...
