What is Expertise? The Experts Disagree
by Louise Rasmussen in Head Smart
Everybody’s an expert these days. Pest Control Expert, Plumbing Expert, Weather Expert, and so on. What does it really mean to have expertise? Take a minute to think about what expertise means to you. If ideas like superior intelligence, heightened perceptual skills, and photographic memory come to mind, you may be thinking of superheroes, or [...]... Read more »

Marijuana and Diabetes: Does Pot Make You Thin?
by Dirk Hanson in Addiction Inbox
Teasing out the insulin effect.
On the face of it, the study seems to come out of left field: A group of researchers claimed that marijuana smokers showed 16 per cent lower fasting insulin levels than non-smokers. The study, called “The Impact of Marijuana Use on Glucose, Insulin, and Insulin Resistance among US Adults,” is in press for The American Journal of Medicine. The authors are a diverse group of medical researchers from Harvard, Beth Israel Deaconess Medical Center, and t........ Read more »

Study Further:
RNA (full form: ribonucleic acid) is a nucleic acid that has the sugar ribose, is found in all living cells, and is essential for the manufacture of proteins according to the instructions carried by genes. RNA also acts instead of DNA as the genetic material in certain viruses.

Dogs can haz brainscanz and EEG?
by CAPB in Companion Animal Psychology Blog
Canine cognition is a hot topic these days, using experiments and brain imaging as research tools. The trouble with brain imaging work is that it is invasive, to the extent that animals may have to be sedated or anaesthetized for the study. All that changed with the amazing work of Gregory Berns et al and the first-ever fMRI study on awake, unrestrained dogs last year. Now Miiamaaria Kujala et al in Finland have shown that it is also possible to do a non-invasive EEG with dogs.An EEG measur........ Read more »

by Mark Lasbury in As Many Exceptions As Rules
It’s no secret that carnivorous plants are just way cool. Yet despite all the attention, there is still a lot we don’t know about them. Recent studies have expanded the view we have of these plants so that we now recognize more and more of them – like tomatoes and potatoes. Yes, our vegetables are insectivores!

Down in the underground, scuds lose eyes but keep genes
by Zen Faulkes in NeuroDojo
When animals live caves full time, their descendents often lose their eyes. It has happened over and over and over and over again, in all different kinds of animals. But how this happens is not obvious. Stephen Jay Gould wrote that some people would use cave fish as an argument that “Lamarck must have been on to something” with his idea that acquired characteristics can be inherited. Well, no, that’s not that case, but it is a good example of how tricky thinking about losses can be.
