One year on!

Today officially marks the first anniversary of Inspiring Science, and it’s been a great year!  I think I managed to make some progress towards the goals I outlined in my first post.  Over the course of the past year, I’ve learned how to make my writing more accessible and become better at engaging with non-scientists, though unfortunately I haven’t managed to write as frequently as I would have liked.  I hope I can rectify that and continue to improve those skills, but I’m also going to try to do a better job of fostering discussion over the next 12 months.  I have a few ideas about how to do that; we’ll see how well they pan out.  (If you have a suggestion, let me know!)

If you’re one of the newer readers, why not take a romp through the archives?  There’s some good stuff buried on there that doesn’t often make it  onto the “What’s popular now?” list in the sidebar.  I’ve also picked five posts from the past year which I wish had received more attention and listed them below; I hope you’ll enjoy them.

  • Natural selection: On fitness
  • Social wasps are specialists at recognizing faces
  • Of moss and micro-arthropods
  • We still don’t know how birds navigate
  • Gene expression: shape matters

With that said, I look forward to another year of writing about science; thanks for reading, commenting and generally keeping me company on this adventure!  If you have any suggestions about what I could do differently or better (or what I’m doing well) please leave a comment so I can learn and improve. 🙂

Flying bacteria: the chemists of the clouds

Tufts of textureA while ago I wrote about how bacteria make their way into clouds, where they act as seeds around which raindrops condense. Now, a team of scientists in France has shown that the microbes floating around in the clouds do more than just make it rain to bring them back down to the surface; they also carry out chemistry while they’re up there.

Fam38A: another piece of the cancer puzzle

Histopathologic image of small cell carcinoma of the lung. CT-guided core needle biopsy. (Image credit: Wikipedia)A team of researchers in the UK have discovered how the absence of a single gene makes it easier for tumour cells to migrate more freely in lung cancer patients. More people suffer  — and die — from lung cancer than any other kind.  Small cell lung cancer (SCLC) is an extremely aggressive form of lung cancer thanks to its tendency to metastasise quickly, spreading to other organs early. In order to migrate, metastasising tumour cells have to break free of the extracellular matrix (ECM), the network of material around our cells which supports them and binds them to each other. That’s where this particular gene, Fam38A, comes into the story. Continue reading →

From chimps to chickens: how a little DNA can make a lot of difference

A stretch of DNA (Image credit: Wikipedia)Humans and chimpanzees famously share more than 98% of their genome and yet the two species look and behave quite differently.  This apparent paradox stretches well beyond our little corner of the tree of life; we share more than half our genes with chickens and those we share are 75% identical.  Two studies published together in the December issue of Science tackled this perplexing discrepancy by showing that there may be more to a genome than meets the eye.

Hsp90: translating environmental stress into evolutionary change

In the 1990s, Suzanne Rutherford and Susan Lindquist were studying fruit flies with a mutated version of the Hsp90 gene and found that the absence of this single gene led to a wide range of developmental defects.  This was surprising not only because Hsp90 isn’t directly related to development, but also because of the remarkable breadth of its impact.  Uncovering how this gene affects so many aspects of development has led to an intriguing story linking responses to environmental stress with the evolution of developmental pathways.

The ABCs of flowers

SunburstIn 1991, researchers at the California Institute of Technology described the basic genetic system behind how flowers are made.  The “ABC model” that they proposed was so popular and successful that it was quickly taken up by the community and was even included in textbooks when I did my undergraduate studies just six years later. I remember being fascinated the first time I heard about it. This was the sort of thing that got me really excited — disparate facts were brought together in an elegant mechanism that could robustly set up a flower but was still flexible enough to create different forms. Now, over a decade later, I’d like to share this inspirational work with you. Continue reading →
