We walk faster these days – really!

It almost sounds like the realms of the Ignoble prize – measuring how fast people walk at different places and times, but actually this study is absolutely fascinating – for once confirming the sort of folk wisdom that so often is debunked by scientific measurement.

An experiment conducted in 32 cities has revealed that average walking speeds have increased by about 10 per cent since 1994….The steepest acceleration was found in Asian “tiger” countries such as China and Singapore, which have experienced particularly marked social and economic change.
Pedestrians in these nations walk between 20 and 30 per cent faster than they did in the early 1990s. Singapore has the quickest walkers in the world. London was the fastest-paced British city, but finished only 12th in the final league table, behind supposedly more laid-back cities such as Copenhagen (2nd) and Dublin (5th).

Of course it then raises lots of interesting questions of interpretation: is this a good or a bad thing? You could easily spin it either way.

Rethinking aging

An excellent piece in the New Yorker about how most modern medicine is getting old age utterly wrong. There’s a fascinating mini-account of a life, and some surprising medical treatment:

She was eighty-five years old, with short, frizzy white hair, oval glasses, a lavender knit shirt, and a sweet, ready smile….She had a high-school education, and during the war she’d worked as a riveter at the Charlestown Navy Yard. She also worked for a time at the Jordan Marsh department store in downtown Boston. But that was a long time ago. She stuck to home now, with her yard and her terrier and her family when they visited.

There’s ET – wave!

Well, not quite, but I’m surprised this story hasn’t got more publicity:

Osiris, which is 150 light years from Earth and has the official title HD 209458b, was the first extra-solar world known to have an atmosphere, mainly composed of hydrogen. But its atmosphere was found to be boiling away into space.
In 2004, astronomers revealed that the planet’s outer atmosphere contained carbon and oxygen, thought to be swept up from the deeper levels by the flow of escaping hydrogen. The new discovery of water vapour emerged from measurements taken as Osiris passed directly in front of its parent star

Animals in peril

You’d hardly think it possible, but a new species of great cat has been identified – the Bornean clouded leopard (Neofelis diardi). Of course you can guess the final lines of the story – numbers are thought to be small, and he species endangered. Sigh.

And an introduced species is facing an equally bleak future – camels, although not native to Australia (and less harmful than the hard-hooved sheep, goats and cattle that tear up the ancient soils) are said to be causing ecological chaos (when they aren’t dying of thirst in the drought), and culls are planned. Or worse…

The plan will examine the economic opportunities presented by the camels, including making them into pet food and building up exports. Australia does not have a licensed camel abattoir, but it exports live camels to South-east Asia, where they are slaughtered for their meat.

These are feral — ie wild — camels. The kind of stress they must undergo during live export doesn’t bear thinking about.

It was a slob what did it

It seems about 3.3m years ago a hominid was too lazy to make his or her own bed and hopped into a handy gorilla’s one – probably after the gorilla had got out. And that was how the human race acquired what would be pubic lice.
