Enlisting evolutionary biology against modern threats

Posted: Published on October 6th, 2014

4 hours ago by Sandra Hines The percentage of mammal species unable to outrun climate change range from zero to low, shown in blue, to a high of nearly 40 percent, in light orange (UWs Josh Lawler, published 2012) . Applying whats known of evolutionary biology could guide efforts to help. Credit: U of Washington To many, the term evolutionary biology encompasses the realm of fossils, dinosaurs and changes over eons. But evolutionary biology has tremendous potential to help solve many of today's pressing problems, according to nine international scientists, including Carl Bergstrom, a University of Washington professor of biology. The scientists point to everything from food security to emerging diseases in their article, "Applying evolutionary biology to address global challenges," published online Sept. 11 by Science. Using evolutionary biology is one way to try to outwit evolution where it is happening too quickly as when pests and diseases adapt rapidly and defeat our attempts to control them and to perhaps find accommodations when evolution occurs too slowly as when species can't adapt to habitat altered by climate change. "Evolutionary biology is often thought of as figuring out things in the past," Bergstrom said. "Very often it's viewed as a … Continue reading →

Researchers develop green tea-based ‘missiles’ to kill cancer cells more effectively

Posted: Published on October 6th, 2014

5 hours ago Image 1: A schematic diagram of the two-step assembly process of the core-shell structure of the green tea drug carrier. The core of this carrier is made of OEGCG and Herceptin, a protein drug currently used to treat breast cancer. Surrounding the EGCG-Herceptin core is a shell containing PEG-EGCG. Green tea has long been known for its anti-oxidant, anti-cancer, anti-aging and anti-microbial properties. A group of researchers from the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR has taken the health benefits of green tea to the next level by using one of its ingredients to develop a drug delivery system, which kills cancer cells more efficiently. A key ingredient in green tea, epigallocatechin gallate (EGCG), is an antioxidant which is known to have therapeutic applications in the treatment of many disorders including cancer. Using EGCG, IBN researchers have successfully engineered nanocarriers that can deliver drugs and kill cancer cells more efficiently. Their work was published recently in the leading journal Nature Nanotechnology. "The numerous health benefits of green tea have inspired us to utilize it in drug delivery systems. This is the first time that green tea has been used as a material to encapsulate and … Continue reading →
