Bonobo Week continues! I'm donating whatever proceeds I receive from my blogging shenanigans for the entire month of June to help the bonobos at Lola Ya Bonobo.
Primate researchers used to think that only humans voluntarily share their own food with others. At the time, it was a reasonable conclusion to make, since lots of studies indicated that chimps don't. But that was before anyone checked to see if bonobos were willing to share their food with others.

For nearly a decade, the public has heeded warnings of suicidal behavior related to antidepressant use in children and adolescents. However, the use of antidepressants in this population is still increasing. Initially, selective serotonin reuptake inhibitors (SSRIs), the most common class of antidepressants prescribed for children, were the only drugs associated with the increase in [...]... Read more »

In a previous post I reported that ‘fascinating stimuli’ are potentially better at restoring attention/vigilance than non-fascinating stimuli (Zainaghi and Bettella, 2009) [here]; and that, in my opinion, this was more effective than going and spending time observing natural settings (Berman, Jonides and Kaplan, 2008) [here].

I’ve decided to write a couple of articles on a relatively underappreciated area of neuroscience: the study of birds. I hope to demonstrate that although the term “bird brain” is used as an insult in everyday bicker, the tiny brains of birds are more complex than they are perceived to be. Bird brains may even be able to teach us a thing or two about the brightest of human brains. In this first post, I will describe birdsong – a rare example of music production in nonhumans.You’ve proba........ Read more »

It’s human nature to think of the big bad animals that eat other animals as powerful and the animals that get eaten as wimpy. Of course, humans are often wrong (see “clusterf**kery”).

Most non-parasitic female bees collect pollen as well as nectar to provision their brood cells. Pollen is brushed from the plant anthers using their front legs and stored on specialised structures on the bee body or legs. Some bees, however, specialize on collecting pollen from flowers with raised anthers, which touch over the bee's head or thorax when bees land on them. These are called nototribic flowers and include species from the Lamiaceae (the mint family) and Scrophulariaceae (the figwort........ Read more »

Some of the most bio-diverse areas of the world are also some of the most impoverished, which is why it can seem cruel to create national parks and other protected areas to preserve these ecosystems.

Mental health charities and campaigners typically claim that one in four of us will experience a mental illness at some point in our life-times. This prompts disbelief in some quarters. The rates can't possibly be that high, so the argument goes, there must be something wrong with the figures. A new study led by Terrie Moffitt confirms that 'Yes', there is something wrong with the one in four figure - it should be one in two!Previous estimates for the prevalence of mental illness are largely bas........
