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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
