Colgate University biology professor Ken Belanger and an interdisciplinary team of researchers from Washington University in St. Louis, Pacific Northwest National Laboratories, and Saitama University are collaborating to better understand how plants protect themselves from naturally occurring but potentially damaging high-energy molecules. Their findings, said Belanger, could one day help farmers boost crop yields and shield their harvests from extreme environmental conditions, and may have even larger implications for aging and cancer research.
The group—which is currently composed of three biologists, one systems engineer, and one computer scientist, and will also soon include Colgate and Washington University undergraduate students—is one of just six in the nation to receive a five-year, $5 million Frontiers in Integrative Biological Research (FIBR) grant from the National Science Foundation (NSF). Colgate’s portion of the funding will total about $60,000 each year.
The study will examine how plant cells defend against high-energy molecules that are produced as by-products of everyday metabolic processes, including photosynthesis and respiration. Called oxygen free radicals, these and other oxidizing molecules can harm DNA and proteins, impairing a cell’s ability to function. Oxidative damage is believed to be one of the primary causes of aging in humans and can potentially cause cells to become cancerous.

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:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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...
