How do people coordinate their actions; how does communication work; how does it affect people; how do minds get in sync? When people communicate they do get in sync but there is no magical about this. We perceive the outside world including signals as well as scenery, we model this input and think about it, […]...

Arthropods have the most amazing structures and functions for taste sense. New research is showing that that insects can taste carbon dioxide, as well as DEET repellent. CO2 helps guide blood suckers to victims while DEET flavor keep mosquitoes from landing or biting.
Turnabout is fair play; caterpillars use taste to poison parasitic larvae within their body. The caterpillars switch to toxic plants when infected. On the other hand, plants can taste caterpillar saliva and initiate defensive s........ Read more »

Do you ever wonder how dogs are rewarded for taking part in scientific research? In some studies dogs are allowed to act naturally, but in others they need to learn something such as how to operate an apparatus they haven’t seen before, or to observe people interacting. Either way, you can’t guarantee canine cooperation. This week we thought we’d take a look at how dogs are motivated during the course of the research itself.Photo: kitty / ShutterstockNeedless to say, food is a common denom........ Read more »

Mitochondria are the cellular power plants, but bigger power plants are not always a good thing. Defects in the regulation of mitochondrial size and dynamics can cause neurodegenerative diseases such as Alzheimer’s disease. Today’s image is from a paper describing an important player in mitochondrial division, or fission. Mitochondria serve as the cellular power plants due to their production of ATP, the cell’s energy source, and are quite dynamic, with fusion and fission events occurring ........ Read more »

The dissociative anesthetic and ravey club drug ketamine has been hailed as a possible “miracle” cure for depression. In contrast to the delayed action of standard antidepressants such as SSRIs, the uplifting effects of Special K are noticeable within an hour. “Experimental Medication Kicks Depression in Hours Instead of Weeks,” says the National Institute of Mental Health. NIMH has been bullish on ketamine for years now. Prominent researchers Duman and Aghajanian called it the “the mo........ Read more »

Vascular compliance is a characteristic of the blood vessel wall to expand or contract with changes in pressure, and is reduced with aging or diseases like arteriosclerosis. Our goal was to investigate how hand-volume changes differ with age and to provide a simple non-invasive method to assess vascular compliance. We hypothesized that gravity-related, hand-wrist volume changes are greater in younger than in older healthy volunteers. Thirty-five healthy volunteers were classified into two age gr........
