Researchers discover mechanism that limits scar formation
Washington, June 12 - Researchers have discovered that an unexpected cellular response plays an important role in breaking down and inhibiting the formation of excess scar tissue in wound healing.When an organism suffers severe injury, specialised cells are 'recruited' to the wound site that rapidly produce extracellular matrix proteins such as collagen to provide structural support to the tissue, ... read more

Protein switch that kills deadly water-based pathogens discovered
Toronto, May 27 - Scientists have discovered a protein switch that will help kill deadly water-based pathogens like E. coli and make for safer drinking water.Zongchao Jia, a professor of biochemistry at Queen's University, and post-doctoral student Jimin Zheng, discovered exactly how the AceK protein acts as a switch in some bacteria to bypass the energy-producing cycle. This bypassing allows dang ... read more

Scientists identify new longevity protein
Washington, May 8 - The level of a single protein found in the tiny roundworm C. elegans determines how long it lives, says a new study.Worms born without this protein, called arrestin, lived about one-third longer than normal, while worms that had triple the amount of arrestin lived one-third less. The research also showed that arrestin interacts with several other proteins within cells to regula ... read more

Keep food out of sight to eat less
Washington, April 27 - Can eating less be as simple as leaving serving dishes on the stove and out of sight?Researchers led by Brian Wansink, director of the Cornell Food and Brand Lab, shared findings of their 'Serve Here; Eat There' study of 78 adults. 'We looked at whether serving foods from the kitchen counter, instead of at the table, would reduce the number of times a person refilled his or ... read more
