Researchers have discovered that T-cells - a type of white blood cell that learns to recognize and attack microbial pathogens - are activated by a pain receptor, according to a new study.
Noses are not the only part of the body that can sense odors, but lungs also have receptors that can perform the same job as nose, researchers have found.
New research done by the University of Michigan reveals the relationship between cold air and the receptor channel, TRPA-1. The TRPA-1 receptor apparently gets triggered by the cold air and starts a chain reaction resulting in the activation of the longevity gene. This research is still limited to roundworms, but the fact that these mechanisms also exist in humans suggests that cold air can lead to loner lifespans for humans as well.
The BioScience Talks podcast features discussions of topical issues related to the biological sciences. By altering the heritability of certain traits, gene drive technologies have the potential to spread desired genes through wild populations. In practice, this could lead to mosquito populations that, for example, bear traits making them resistant to the spread of malaria. Despite the huge potential for improving human well-being, concern exists that gene drives could fail in the wild or, perhaps more concerning, spread beyond their intended target populations.
