Freaky bioluminescent creatures from the deep on TED.com

Hilary Miller Apr 20, 2010

A great new video out on TED.com today has Edith Widder describing some clever applications of bioluminescence in deep sea organisms. Some 80 to 90 percent of undersea creatures make light — and we know very little about how or why. Bioluminescence expert Edith Widder explores this glowing, sparkling, luminous world, sharing glorious images and [...] … Read More

Play your genes

Hilary Miller Apr 14, 2010

Ever wondered what your favourite gene would sound like if it was a melody? Well here’s a website where you can find out.  Basically what it does is take the DNA sequence, convert it to amino acids, and assign each amino acid to a musical note (with some modifications to make it more musical, described [...] … Read More

Tasmanian devil facial tumour disease: too good a match for the immune system

Hilary Miller Apr 13, 2010

A central premise in conservation genetics is that high genetic diversity is good for a species’ continued survival, and low genetic diversity is bad. This seems intuitively obvious (after all, we all know that you shouldn’t marry your cousin) but actually finding examples in nature where we can say for sure that low genetic diversity has [...] … Read More

Eye colour inheritance update #1

Hilary Miller Mar 17, 2010

To update my post on the inheritance of human eye colour (as I’m sure you are all dying to know), the little monkey was born with dark grey eyes.  No surprises there as most newborns are born with eyes this colour.  Six weeks on, her eyes are taking on a distinct blueish tinge, with a slightly [...] … Read More

Feb round-up

Hilary Miller Feb 26, 2010

Well this month has been a pretty unproductive one for blogging, but extremely productive in other ways as I welcomed my new daughter into the world on Feb 2nd.  In amongst the endless feeding, dirty nappies and general sleep-deprived haze, I have occasionally managed to get online and thought I’d share a couple of evolution-y things that [...] … Read More

Convergent evolution unites bats and dolphins

Hilary Miller Jan 29, 2010

A nice example of convergent evolution has been published in the latest issue of Current Biology, with two studies showing that echolocation abilities of bats and dolphins have the same underlying genetic basis.  Convergent evolution is where two species independently acquire the same trait in response to similar evolutionary pressures.  There are a huge number of [...] … Read More
