You might hear about Rosetta in the news later this week, so I decided to give my readers a head-start with an introduction to the mission and its objectives, as well as an idea of what to expect. Continue reading →

Angelina Jolie at the 2010 Comic Con in San Diego (Photo credit: Wikipedia)Fifteen years ago it was the stuff of science fiction.  Now, you can just swab your cheek, send it to a company and, for only a few hundred euros, have your DNA analyzed.  You’ll find out about your ancestry and your predisposition towards certain inherited diseases or conditions (from cancer and diabetes to myopia).  You’ll also learn if you’re a ‘carrier’ — that is, if you’re carrying a gene that won’t affect you but might affect your children.  You can even get information about more light-hearted issues like whether you’re likely to have fast- or slow-twitch muscles or your ability to taste certain bitter flavours.  The technology is pretty great, but it also raises some interesting questions which I thought would be worth discussing (especially since I really enjoyed our previous discussion).

I’m thrilled to announce that I’ll soon be writing for a second blog in addition to Inspiring Science!  The Scitable blog network, part of Nature Education’s online collaborative learning space, will be relaunching sometime soon and I’ve been asked to be one of the authors of the new blog about evolution.  Joining me will be Sarah Jane Alger, who currently writes about animal behaviour on her excellent blog, The Scorpion and the Frog.

A few thoughts on science communication

I originally wrote this as a guest post for Speaking of Science, a blog that tries to “de-mystify science communication by offering interviews, news, and anything else about it.”

When Julie asked me to write about why I think science communication is important, I started jotting down a list of reasons. Science has an undeniable impact and prominence in our world, which has benefited from the accumulated fruits of centuries of research. As citizens, we shape this world and are shaped by it, so it’s important to understand the science behind the questions we’re discussing, from antibiotics and GMOs to the value of a Mars mission or research in theoretical physics.  This kind of understanding can also be important on an individual level. Knowing more about how your body works can help you make informed decisions about diet and lifestyle or medical procedures — or even what kind of birth control to use. These are important aspects of science communication, but they’re not really a source of inspiration to me or a guiding factor in deciding what I write about. Science communicators do have a responsibility to fulfil a role in mediating these discussion, and though I try to keep aware of that and contribute, it’s not where my passion truly lies.

Laboratory mouse (Photo credit: Wikipedia)According to a recent study, your chances of developing adult onset diabetes may depend on what kind of bacteria are living in your gut.  It’s been known for some time that type 2 diabetes can be caused by a combination of genetic and lifestyle factors; over the past few years, it’s become clear that these factors somehow interact with the microbiome, but the nature of this interaction and the microbiome’s role in determining susceptibility to diabetes hasn’t been properly explored.  Last year a team of scientists from Brazil published results showing that changes in the community composition could completely reverse the effect of genetic factors.

Natural selection: On fitness

For the third part in my series about natural selection I’d like to address the concept of fitness.  Thanks to the phrase “survival of the fittest”, fitness is quite a prominent idea in the popular perception of evolution.  It was originally coined by Herbert Spencer after he read On the Origin of Species; Darwin adopted the phrase in later editions and it’s been popular ever since.  Unfortunately, this glib phrase has often eclipsed a more accurate depiction of evolution, leading to some common misunderstandings.  This confusion arises because “fitness” has a different meaning in evolutionary biology than it does in general usage.  (Have a look at the earlier posts in this series if you haven’t already read them; the first was about the different modes of natural selection and the second discussed selection mechanisms, focusing on sexual selection in particular.)
