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.

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
