The BA Festival of Science: Death by bladder stone

Posted by Katrina Charles, BA Media Fellow

This morning I went to see a speaker talk about the tragic death of a young girl, killed by a chronic urinary tract infection. This infection resulted in the growth of bladder stone, leading after some years to renal failure and finally death.

Why is this special?

Because this girl died between 1,000 and 1,300 years ago and the rare find of a urinary stone provides a wealth of data for forensic scientists.

The BA Festival of Science: We need to discuss creationism in school science. Trust me, I was a biology teacher.

Posted by Katrina Charles, BA Media Fellow

Reverend Michael Reiss is the director of education at the Royal Society. And he is advocating discussing creationism in science classes. And he has a PhD in evolutionary biology. Hang on a second, this doesn’t look like the recipe for a standard creationism debate.

The BA Festival of Science: Unintended consequence of LHC?

Posted by Katrina Charles, BA Media Fellow

The launch of a new European Space Agency (ESA) satellite has been delayed. The Gravity field and steady-state Ocean Circulation Explorer (GOCE) was due to be launched today (its mission is to map the Earth’s gravitational field in unprecedented detail) but the launch has been delayed until October 5 due to dodgy sat nav.

Perhaps they realised that the competition from the LHC, aptly renamed the License for Huge Coverage on the Great Beyond, might ruin their big day?

On Monday, ESA’s Launch Campaign Manager Jürgen Schmid was reported on ScienceDaily as saying that “So far the GOCE launch preparation activities have gone quite smoothly”. The same day, they reported that launch preparations had stopped “due to an anomaly identified in one of the units of the guidance and navigation subsystem”.

In a press conference today at the festival organised by one of the funders, the Natural Environment Research Council, Marek Ziebert from University College London let slip that this problem has happened before on a different launch. Ziebert suggested that it was the responsible thing to delay the launch until it was fixed. Not just bad timing then?

The BA Festival of Science: Happy Birthday to the t-test

Posted by Katrina Charles, BA Media Fellow

Right, now that all the fuss of the LHC is over [far from it – Ed.], we can get back to interesting science – statistics.

One hundred years ago this year, “Student” (William Sealy Gosset) published his new statistical hypothesis test for looking at whether differences in small data sets were due to chance, or were actual differences. To honour this landmark centenary, the President of the BA Mathematical Sciences section, Stephen Senn, gave what was a very amusing (I’m talking laugh out loud funny) presentation about the history of the t-test. Of course there was some maths in there too, but after a long day it was easy to glaze over for those bits.
