A Purdue University researcher has successfully engineered plants that may not only lead to the production of anti-carcinogenic nutritional supplements, but also may be used to remove excess selenium from agricultural fields.
This photograph shows the presence of two different selenium compounds in living plant tissue. The image on the left shows a high concentration of MSC, the selenium compound shown to have anti-cancer properties, in one of the plants leaves. The image on the right highlights a different selenium compound in the same leaf. The image was obtained using a technique called X-ray absorbance spectroscopy, or XAS, to visualize concentrations of selenium. Red indicates regions of high concentration. Blue and green indicate lower concentration. (Images courtesy of Ingrid Pickering, Proceedings of the National Academy of Science, 97(20); p. 107110).
By introducing a gene that makes plants tolerate selenium, David Salt, professor of plant molecular physiology, has developed plants capable of building up in their tissues unusually high levels of a selenium compound. His interest in selenium stems in part from recent research sponsored by the National Institutes of Health showing that selenium can reduce the risk of developing prostate cancer by 60 percent.
"We now know how to genetically modify plants so they will make this anti-carcinogenic selenium compound," Salt said. "This research gives us the genetic means to manipulate the amount of this material thats produced in any plant."

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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...
