Virginia Tech researchers receive $2 7 million grant to study mosquito s biological timing

Virginia Tech researchers receive $2.7 million grant to study mosquito s biological timing Mosquitoes may be small, but they are a formidable foe. Not only can they smell over 400 chemicals that we emit and detect the carbon dioxide we breathe out, but they can even adapt their daily behavior in response to our own. With the help of a $2.7 million grant from the National Institute of Allergy and Infectious Diseases (NIAID), researchers at Virginia Tech are now investigating how mosquitoes adjust their olfactory, or smelling, rhythms in response to changes in our own daily activity. Mosquitoes are sometimes described as the deadliest animal on Earth. What we are seeing is an increase in the rate of mosquitoes that become resistant to insecticides and have some other level of behavioral resistance. We need another tool or other tools to control mosquito populations.

New live cell models lay the groundwork for studies into mitochondrial diseases

New live cell models lay the groundwork for studies into mitochondrial diseases The mitochondrion has garnered quite the reputation for its role as the powerhouse of the cell. These tiny, but mighty organelles play various life-sustaining roles, from powering our own cells and organs to fueling chemical and biological processes. But when they aren t working properly, a number of rare diseases can occur. Mitochondrial diseases are a group of debilitating genetic disorders that affect one in 5,000 people throughout the world, most of them being children. Along with these diseases come a variety of health concerns including, but not limited to, heart disease, developmental and cognitive disabilities, respiratory issues, poor growth, and even premature death. As of this moment, there is no cure.
