Cinematic Highlights at the BSDB Meeting 2011

Posted by on July 5th, 2011

As promised, in this final part of my meeting report on the BSCB-BSDB Spring Conference 2011 I will highlight a couple of talks which came with visual effects – studies involving live imaging. I prefer to watch these movies in seminars rather than downloading them with a paper because getting live explanations can make things[…]

Meeting the worm community

Posted by on July 1st, 2011

Last week I attended the 18th international C. elegans meeting at UCLA, organised by the Genetics Society of America. Having done most of my scientific training with mammalian cell culture, I had never been to an organism-specific meeting – let alone one about worms – and I was curious to find out what it would[…]

Time flies when you’re having fun

Posted by on June 22nd, 2011

Exactly one year ago today, we launched the Node. Since then, we’ve accumulated a good number of regular readers, and some enthusiastic contributors. We’ve covered meetings, research, news, images and other topics – all with a focus on developmental biology. It seems like this past year just flew by. Really, where did the time go?[…]

How fate determined my career as a science journalist

Posted by on June 21st, 2011

If I shut my eyes, I can still picture  the young boy dressed as a gravedigger. He’s taking centre-stage, flourishing a spade and cheerily telling his audience that if they don’t practise safe sex, they will die of AIDS and boost his business. It’s not the sort of thing you expect from a Sunday school[…]

In Development this week (Vol. 138, Issue 14)

Posted by on June 21st, 2011

Here are the research highlights from the current issue of Development: How to make stripes: revising the pair-rules A key step in Drosophila segmentation is the transition from non-periodic to periodic gene expression patterns, a process that is controlled by transcriptional regulation of the pair-rule genes. Primary pair-rule genes generate their striped expression patterns through[…]

Of mice and women: how Notch signaling ensures a healthy pregnancy

Posted by on June 21st, 2011

Nathan M. Hunkapiller and Susan J. Fisher To accompany our research article in issue 138 (14) of Development, “A role for Notch signaling in trophoblast endovascular invasion and in the pathogenesis of pre-eclampsia,” we have been asked by the Node to provide a broader context to the work and to explore the possible medical implications[…]

A trip down memory lane

Posted by on June 21st, 2011

Tomorrow is the Node’s first birthday, which means we’ve been online for a year now. We’ve taken a look at the archive of the past year as a reminder of what we’ve featured on the site. Please join us on this trip down memory lane. A quick look back at the Node’s first year: June[…]

Mathematical and Computational Modelling at the BSDB Meeting 2011

Posted by on June 20th, 2011

Here is part 3 of my report on the 2011 BSCB-BSDB Spring Conference this April in Canterbury. In the first part, I covered Mark Krasnow’s amazing opening lecture on lung development, and in part two I introduced this year’s awardees of the BSCB and BSDB honorary medals. Here I’ll highlight some of the talks in[…]

X in Space (Now in 3D)

Posted by on June 20th, 2011

The 3D spatial arrangement of DNA within the nucleus is tightly controlled and has great functional significance. Each chromosome has been shown to occupy a defined nuclear territory and the expression of genes is often closely linked to where they are located, with similar expression levels seen for genes with similar locations. It has also[…]

Woods Hole image winner

Posted by on June 20th, 2011

Congratulations to Meii Chung of UT Austin, whose image of a Cerebratulus pilidium larva won first place in the latest voting round to choose a cover for Development from images taken by students of the 2010 Woods Hole Embryology course. Pilidium larva of the Nermertean, Cerebratulus lacteus. Acetylated tubulin (green), serotonin (red), nuclei (blue, DAPI).[…]
