Intelligence tests have to be adjusted all the time because people score higher and higher. If the average human of today went 105 years back in time, s/he would score 130, be considered as gifted, and join clubs for highly intelligent people. How can that be? The IQ growth The picture above shows the development […]... Read more »

One thing you won't find in the story of the Very Hungry Caterpillar is the part where after transforming into a butterfly, he mates with a female who has a Very Hungry Reproductive Tract waiting to devour his sperm. She has a special digestive organ just for this purpose. It's so powerful that it could even compete with the gut that let the caterpillar, in his more innocent days, chew through those five oranges.
This sperm-hungry organ is called the bursa copulatrix. In female butterflie... Read more »

One of the seminal pieces of research on religion and society was done in the early 20th century by a guy named Max Weber, who concluded that what he called the ‘Protestant Work Ethic’ helped explain why the countries of Northern Europe and America were so prosperous. It’s a provocative conclusion that later research has shown was [Read More...]... Read more »

When something goes bump in the night, most of us are little jumpier than we would be in the day. But is that just because it's dark, or is it more to do with our bodies and brains switching to a vigilant nocturnal mode?Yadan Li and her colleagues have attempted to disentangle the influences of darkness and nighttime. They recruited 120 young women to complete a computer task in a windowless cubicle, which involved them looking at neutral pictures (e.g. nature scenes), scary pictures (e.g. spide........

Nature’s most interesting secrets can sometimes be found in our own backyards. One such secret is related to all birds, those pigeons, thrushes and sparrows that we see everyday. This familiarity means that we do not think too much of birds passing them by on our way to work or school. However, if the birds […]... Read more »

I'm looking at two papers today which I'd like to think cover the title of this post pretty well dealing with the plurality of autism - the autisms - and the idea that intervention or management-wise, there is no 'one size fits all' when it comes to the autisms.First up are the findings reported by Ziats and colleagues  who presented results for a child - "A 4-year-old male with autism and two episodes of neurodevelopmental regression" - who was also found to have a "mutation in the TMLHE gen........

The DNA encoding all life on Earth is made of four building blocks called nucleotides, commonly known as “letters,” that line up in pairs and twist into a double helix. Now, two groups of scientists are reporting for the first time that two new nucleotides can do the same thing — raising the possibility that entirely new proteins could be created for medical uses....

The recent announcement of the discovery in stone tools in Kenya dating to 3.3 million years ago (MYA) has been greeted with a lot of fanfare.

Can people be blamed for dog training mistakes when there is so much erroneous information out there?Recently I saw a man walking a German Shepherd. Even from a distance it was clear the dog was nervous: his posture was low to the ground and the way he was walking made me wonder what kind of equipment he was on. As I waited at the traffic lights, I got a chance to see: a prong collar, tight, positioned high on his neck.There are easy alternatives, the simplest being a no-pull harness. I began to........

Fiddler crabs are an evolutionary marvel. Their major claw is huge, it plays a role in mate selection, but not just in the way you’d think.
Some species are right-clawed and some can have the major claw on either side, but if they lose one and grow it back, the major claw might switch sides! The new major claw isn’t as good for fighting, so he fakes being strong and tries to win without fighting.

An amusing editorial in the neuroscience journal Cortex discusses the excuses scientists use to explain why they didn't submit their peer reviews on time:
Following our nagging for late reviews, we learned that one reviewer had to take their cat to the vet, another was busy buying Christmas presents, one was planning their holidays, an unfortunate one had their office broken into [...] others agreed to review whereas indeed they really intended to withdraw, or were just too busy to reply.
