European bee populations are on the decline worldwide. Who cares? These bees are major pollinators of crops and therefore perform, for free, a vital ecological service worth about $U.S. 14 billion per year. Not to mention the many other species of non-crop flowering plants that reproduce with the help of insects like this.
The recent kind [...]... Read more »

That's right - contrary to what many religiously believe, it is the inability to grow more fat during times of energy surpluss, rather than the excess of fat which appears to directly contribute to the metabolic consequence often associated with obesity.
A recent article in the New Scientist shines some light on this issue;
Obesity kills, everyone knows that. But is it possible that we've been looking at the problem in the wrong way? It seems getting fatter may be part of........ Read more »

I've already mentioned one of the papers from the big 25th anniversary issue of JNABS. I've now read a handful of these papers, and they continue to be very interesting and a little bit annoying. Why are they annoying? Well, I like the review aspect of the papers, I don't like the "JNABS played X role in the development of X concept", because, really? Who the hell cares? This is a perfect ...

Early spring is a good time of year. Sci starts feeling a little more motivated, it's finally warm enough to feel comfortable running outside again (not that Sci ran inside, she was just very uncomfortable outside), and it's asparagus season!
When Sci was wee and her mother would try to feed her asparagus, Sci turned up her little nose at such nonsense. Why on earth would anyone eat something that was that green and looked like it had hair!?

Attention can be focused or it can be diffused. Attentional focus has been shown to be affected by mood or affect; with positive affect leading to a broadening of attentional focus; and negative affect, in general been shown to be associated with a narrowing of focus.

Measles infection in a brain cell nucleus
Having gone through Parts I, II, III, and IV of Measles week, let’s finish up by asking what this means for measles vaccine.

Information, information, information. That's the message from one of the first studies to look at people's preferences for different forms of advice. Reeshad Dalal and Silvia Bonaccio presented hundreds of students with fictional decision-making scenarios, such as choosing which job to apply for. The students were offered various permutations of advice and asked to say how satisfied they'd be if a friend had given them that advice. The different kinds of advice were: which option to go for; whi........ Read more »
From all the newspapers in the last seven years in British national newspapers about 348 mentioned ECT or electroconvulsive therapy or electroshock and it’s other synonyms. Overall 111 articles (31,9%) portrayed ECT negatively, 198 articles were neutral and 39 were positive. A substantial comment on ECT was published in 44 (12,6%) articles. The negative comments [...]

Bacteria found in major cigarette brands.
It’s not enough that smoking causes all manner of cardiopulmonary complications, or that more than 3,000 chemicals and heavy metals have been identified as additives. Now comes evidence that tobacco particles extracted from cigarettes contain markers for hundreds of known bacteria. Lung infections in some smokers may be caused by germs on shredded tobacco, rather than the act of smoking itself.

The New York Times recently covered a paper by Grey and Tickle-Degnen, published in the journal Neuropsychology, finding that people with Parkinson's Disease (PD) are not able to recognize facial and vocal emotions very well. The article states that it's not clear why this seems to be the case. I briefly reviewed the original meta-analytic paper (the pdf can be found here) and saw that the research team accounted for 1) the emotion recognition tasks used, 2) the medication the participants were ........

Over the past 30 years, stampedes have killed at least 7,000 people and injured another 14,000. That's the conclusion that Edbert Hsu (Johns Hopkins Medical Institutions) and colleagues reached after a painstaking trawl of news reports in the world's English-language media.The real toll is probably even higher, of course, but the data were enough to allow Hsu to work out the characteristics of the most lethal stampedes. They found reports on 215 stampedes, of which 49 occurred at sporting events........ Read more »
