Patients who have had colorectal cancer may reduce their risk of suffering a recurrence by taking an aspirin daily, according to a new study conducted by a University of North Carolina at Chapel Hill physician and colleagues around the United States.
The study showed that subjects who took 325 milligrams of aspirin each day had a 35 percent lower risk of developing polyps in their colons during the period examined than did patients who received an inactive placebo. Polyps are considered precursors to most colorectal cancers. A report on the findings appears in the March 6 issue of the New England Journal of Medicine. More than 100 medical centers and clinics throughout the United States participated in the study.
"From both animal research and observational studies, weve recognized for a long time that aspirin might decrease the risk of colon cancer," said Dr. Robert S. Sandler, the studys principal investigator. "To find out whether aspirin really worked, we needed a randomized trial where we could compare aspirin with a placebo. With the help of a large consortium of hospitals and a large number of patients, thats what weve done. "

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

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,...
