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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
