It seems that mosquitoes use human body odor to locate suitable hosts, and different people smell differently to mosquitoes.
PCBs are synthetic molecules that were used in transformers, electric motors, and more applications. It was quickly discovered that these molecules are toxic, and subsequently, they were banned.
Often in animal research, animals with a certain genetic alteration are compared to a “wild-type”. One might assume that there is no differences between wild-types, but many different strains of wild-type animals are used.
A large number of genetically engineered mouse models are available to study different aspects of Alzheimer’s disease.
Brains are complicated. We all know that. Like an entangled bunch of wires. Still, over the years, neuroscientists have been able to map out several brain regions and their functions in behavior and physiology.
I recently wrote about other translations from rodent studies to zebrafish, such as the investigation of learning and memory and social behavior. Now it’s time to talk about anxiety and exploration.
To find out more about human and animal learning and memory, we might just have to go to sleep. Ahem – research on sleep, I mean.
Hallucinogenic drugs (psychedelics) have a growing significance in biopsychiatric research. Zebrafish are a popular animal model and seem highly sensitive to various drugs of abuse.
Zebrafish is the new rat. Or mouse. More and more rodents in the lab are being replaced by these nifty little striped fish. They are easy to maintain, reproduce and develop rapidly.
