Smokers can add pre-cancerous growths in the colon to the host of increased health risks they face, according to two studies presented at the 69th Annual Scientific Meeting of the American College of Gastroenterology. Researchers at Our Lady of Mercy Medical Center examined the relationship between polyps and dietary and recreational habits as well as medications in a prospective study of 157 patients with a mean age of 55 years and found smokers faced a significant risk of developing colon polyps – precancerous growths in the colon.
The researchers gathered a range of demographic and health information, including smoking history and use of herbal and nutraceutical supplements including vitamins and minerals, among other information. Participants underwent colonoscopy screening to detect polyps and colorectal cancer.
The researchers found cigarette smokers were more likely to have polyps, to have a greater number of polyps, and to have larger polyps than non-smokers. A logistic regression analysis determined a four percent increased risk of polyps for every additional year of smoking.

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...

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...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
