The evil that men (and women) do lives after them...


Some penguins for Ruth...

A disturbing New Scientist Environment newsflash came today about work done by Heidi Geisz, a marine biologist at Virginia Institute of Marine Science in Gloucester in the US. (As you probably know) DDT was widely used as a pesticide from the late 1940s onwards, but was banned in many countries since the 1970s and these days its usually only used to control disease-bearing mosquitos However DDT has been showing up in tissue samples from Adélie penguins. If this was DDT that had been around in the foodchain for 30-40 years, then the scientists would expect to find DDE (a DDT breakdown product). Turns out, there were large deposits of ice in Antarctic glaciers in the 1950s and 60s and the DDT has been sequestered there for the last 50-odd years, only trickling out now as the glaciers melt. Fortunately, the levels aren't high enough to harm the penguins, but they're worried that other toxins (eg dioxins, PCBs from refrigeration) may also be being released. It really makes you realise how even relatively short periods of pollution can have long-lasting, far-reaching effects (cos I'm guessing DTT was never sprayed in Antarctica!).

Monkey bums

This morning our spam blocker at work blocked an email with the subject line "FW: 'Critter cams' reveal animals' secret lives", which contained such gems as Long legs really are more sexy and How primate porn reveals what we really want. Methinks New Scientist sometimes goes for the sensationalist headlines.

More disturbing (but probably also contributing to the block), was Study reveals sex bias in science, which showed that after in the 4 years after double blind peer review was introduced by Behavioural Ecology Journal, 8% more female authors were published than in the preceding 4 years... actually, I think I should really read what factors were considered in the original article, because I can think of a number of reasons other than outright sexism why this might be the case... not least the tendency of senior researchers to prefer research done by their mates (on the surface this really can look like a boys club).

Also extremely disturbing and sad, the unsurprising 'news' from a study in The Lancet that a third of child deaths could be prevented similarly by adequate nutrition of children or their breast-feeding mothers. I wish I knew where to start...

David Attenborough's next series Life in Cold Blood, should hopefully help to popularise reptiles, which is just as well given that, sadly folk medicine is causing many reptile species to become endangered. The Critter cams of the title really are pretty cool though!

In further dodgy social science... smelling chocolate chip cookies can make you more likely to break your budget, so watch out for yummy smelling clothing stores!

More usefully (glad to see there is still some research funding for medicine), it looks like researchers can detect protein markers for the early stages of breast cancer in saliva and are currently trying to develop a 'lab on a chip' saliva test which they postulate could be administered by dentists. Here's hoping they'll succeed and the test is not prohibitively expensive!

At home packing (can you tell?) to head off to Welly to express my (even) geekier side at Kapcon, so tata 'til Tuesday at least...

Pat yourselves on the back and carry on consuming

On-line carbon counters appeal to me in the same way that calorie counters do... provoking guilty fascination and a persistent nagging knowledge that I really ought to do something about my consumption. So when I read this, I thought I might check out how to "learn about ways to reduce emissions, and contribute to one of the least addressed and most important ways to combat climate change -- protecting existing tropical forests" here. It turns out that you can "offset your own emissions" by donating money to help save rainforests in South America. I can't deny it's a worthy cause, but the implications make me feel kind of sick (so maybe I'll just fly to Bali to meet all my mates for a chat about how people with less money than us could reduce their emissions).
