Weta is not just the name of a special effects studio; it’s the common name for one very large insect (pictured) that is found in New Zealand. Like many animals on New Zealand, it’s under a bit of pressure from introduced mammals, so there are definitely conservation implications if you can understand the mating system of the animal.
Wetas make an interesting case study for studying body size and mating, because they are large for their lineage, and there’s also a big size difference be........ Read more »

Faces are special. Humans are innately interested in faces and so good at detecting them that we see them in clouds, shrouds, pieces of toast, tree-stumps, and even simple yellow circles with a couple of dots in them. Even newborn infants (really, really newborn) are more interested in looking at faces than non-faces. Not too surprisingly, this preference and ability extends to other species too. Monkeys reared from birth with absolutely no visual exposure to either monkey or human faces........ Read more »

Presenting diverse political opinions: how and how much Proceedings of the 28th international conference on Human factors in computing systems : http://doi.acm.org/10.1145/1753326.1753543Can we ever be convinced by someone we usually disagree with completely?

Since I’ve been talking about the possibility of admixture with “archaics” (I’m starting to think the term is a bit too H. sapiens sapiens-centric, is the Neandertal genome turning out to have more ancestral alleles?)

Landslides kill thousands of people each year across the world but, strangely, there are very few studies of the causes of the injuries and deaths that people suffer when they are affected by a landslide. This contrasts with avalanches, which has a long track publication history of causes of mortality. This is important in the context of treatment of victims - in particular, where a rescue is ongoing, the medical practitioners need to be able to prepare for the likely state of those who mi........

Many neuro-imaging studies claim to have investigated what happens in the brain when people interact socially. To overcome the awkward fact that participants have to lie entombed in the bore of a large magnet, these studies have used various means to simulate a social interaction. This includes: having participants watch videos of social interactions; interact with an animated character; or play a game with a human opponent (usually computer controlled) supposedly located in another room. Such m........ Read more »

More genetic and other studies of long-lived people are taking place these days, which means a faster flow of results than has been the case in past years. Part of that can no doubt be attributed to an increased interest in manipulating the aging process in the scientific community, as well as the continually falling cost of the tools needed to run such studies. While perusing PubMed recently, I noticed a few new reports from ongoing longevity studies starting with one from the Leiden Study in t........ Read more »

A few months ago, in the February issue of Archives of General Psychiatry appeared this study (1) title, "Escitalopram and Enhancement of Cognitive Recovery Following Stroke."The design was simple: a placebo group, an escitalopram group, and a problem solving therapy group (a manual based therapy to treat depression in the medically ill). No patients in this group met diagnostic criteria for Major Depression (so why the PST group?) according to the Hamilton Scale for Depression (HAM-D)........ Read more »

It’s well-known that many liquid metals can be cooled below their freezing point. This is, scientists assume, due to dense and symmetric, but non-periodic ordering within the liquid. This theory implies that the freezing point of supercooled metal liquids can be controlled, just like crystallization can be induced by a template – all it takes [...]... Read more »
