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.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
