With increasing demand for effective separation of small-molecule gases – think of carbon caption and storage – there has been a lot of research recently into strategies and materials suitable for those applications. The traditional way to separate gases like nitrogen, oxygen or carbon dioxide is to freeze them out one by one, which is [...]... Read more »

Around the web, headlines are buzzing about alleged evidence for life on Saturn’s biggest moon Titan, citing a paper which noted a suspicious lack of hydrogen build-up in the lower atmosphere and listing among many a mundane explanation, the possibility of methane-based life. Now, while on this blog I discussed that it’s not impossible to [...]... 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]. We’ll in looking at that I’ve tried a few [...]... Read more »

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”). Copepods get eaten by lots of animals—even by critters like jellyfish and right whales, which are known for their lack of speed—but they’re [...]... Read more »

I briefly discussed yesterday the content of this six-session group-based cognitive behavioural approach for chronic pain, delivered in the community.

While Epicentre’s novel Nextera™ technology is revolutionizing next-generation sequencing library preparation, many laboratories are still using older methods of creating genomic DNA libraries for next-generation sequencing.

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. Aren’t the human lives in those regions more important than plants or other animals? Some research has supported the idea [...]... Read more »

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........

A while ago a resident in dermatology told me she got many hits out of PubMed, but zero results out of TRIP.

Searching TRIP for alopecea (in the title) only, we found a Cochrane [...]... Read more »

Male jumping spiders (Phidippus clarus) size one another up before engaging in a fight—whether the aggression is based on rights to mating or territory—and in many cases, the pre-fight displays are sufficient to deter physical contact. The males do not nest but instead wander between female nests looking for opportunities to mate. The females, on the other hand, are not nomads—they build nests from silk and leaves in which they wait while they draw closer to sexual maturity.

How high did the sauropod dinosaurs hold their heads?
