Right, it’s about time this blog went extragalactic again. As Douglas Adams wrote, “Space…is big. Really big. You just won’t believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space”. With all that Universe available [...]... Read more »

There are some days I despair that the biopsychosocial model will EVER take hold in the died-in-the-wool medical interventionist strongholds.

The practice of growing food and keeping livestock was invented numerous times throughout the world. One 'center' of agriculture is said to be the Middle East. Despite the fact that calling the Middle East a "center" in this context is a gross oversimplification, it is true that agriculture was practiced in Anatolia and the Levant for quite some time before it was practiced in Europe, and it seems that the practice more or less spread from the middle east across Europe over a fairly long perio........

If we accept that language is not only a conveyer of cultural information, but it is itself a socially learned and culturally transmitted system, then an individual’s linguistic knowledge is the result of observing the linguistic behaviour of others. This well attested process of language acquisition is often termed Iterated Learning, and it opens up [...]... Read more »

This one’s an old bit of research, but a favourite of mine. It’s not groundbreaking science, but when I first heard about it, I just went ‘oh, wow’, in amazement at what natural selection can come up with! In short, it’s a flower shaped to reflect sonar so that bats can find it.

Good morning and welcome to another installment of "The Falsehoods." Today's falsehood is the assertion that the poor have more babies than the rich, or that the poor just have more babies to begin with. In comparison to ... whatever.

What do stunted coconut palms, misshapen potato tubers, and peach trees with necrotic branches have in common? They are three of the numerous crops stricken with diseases caused by viroids, an astonishing group of minimalist plant pathogens. There isn't much to a viroid, just one single-stranded, circular RNA molecule. The largest viroid genome so far is 399 nucleotides, the smallest a mere 246—about one tenth the size of the smallest viruses (hepadnavirus LINK 2) and one hundredth the size of........ Read more »
Räty & Carlsson-Kanyama show that energy consumption differ according to gender. Not surprisingly, men eat more meat, drink more alcohol and buy and drive more expensive and fuel-intensive cars, and women use more energy on hygiene and clothes. This might not be news, but it’s still nice to have some number on it. Even if those numbers are only (very reasonable!) guesstimations based on a small subset of the population (singles) and inferring energy use from expenditure numbers&hellip........ Read more »

National Geographic has an interesting report on predator-prey issues in national parks: apparently pregnant moose in Yellowstone National Park and Grand Teton National Park tend to shift their activity closer to roads before giving birth, in order to avoid predation by grizzly bears.
According to the results of the study, bears tend to be much more wary of roadways than moose. Grizzlies usually give keep at least a 5000 meter clearance, while moose have been recorded giving birth with........ Read more »

If I step aboard a crowded train and see that the only free space is a cramped mid-seat gap, sandwiched between two tired-looking commuters, and faced directly opposite by three further passengers squashed close under a detritus of newspapers and laptops, then I will invariably choose to stand.
