Embryological Discovery in Woods Hole

Posted by on July 14th, 2010

Three weeks ago, we joined a group of twenty-four students from around the world arriving in the small town of Woods Hole, Massachusetts. We were strangers from all sorts of backgrounds, but we were drawn together by one commonality – a deep interest in developmental biology. We are all here to participate in the Marine[…]

In Development this week (Volume 137, Issue 15)

Posted by on July 13th, 2010

Here are the research highlights from the new issue of Development… TORc1-ing about stem cell differentiation In adult tissues, the tight regulation of stem cell selfrenewal and differentiation maintains tissue homeostasis. In Drosophila ovaries, BMP signalling from the local environment maintains germline stem cells (GSCs) by repressing bam (a differentiation-promoting gene) expression. Now, on p.[…]

Digital fly embryo

Posted by on July 5th, 2010

Using light microscopy to study developmental processes in situ is a bit tricky if your samples are not transparent. In that aspect, early zebrafish development is a walk in the park compared to studying non-transparent fly embryos, or even fish in a later stage of development. But research published in Nature Methods this week comes[…]

ISSCR meeting

Posted by on July 1st, 2010

Almost four thousand people attended the International Society for Stem Cell Research (ISSCR) meeting in San Francisco in June. According to the San Francisco Chronicle, about a quarter of the attendees were from California, but other participants traveled from Australia, Europe, and Asia to attend the meeting. There were far too many talks to summarize[…]

The Young Embryologist Meeting, 2010. London.

Posted by on June 23rd, 2010

May 10th 2010 marked the second anniversary of a very young but promising scientific meeting, the Young Embryologist Meeting (YEM). This meeting was organised by a group of PhD students and young post-docs from London interested in developmental biology but open to everyone. Researchers at this level are just beginning to make decisions on what[…]

Selaginella in frame

If you are a plant developmental biologist studying the Selaginella spikemosses, you might be interested in this beautiful animation that shows the life cycle of the Selaginella, Selaginella apoda Life Cycle: Selaginella apoda from Ciaran Moloney on Vimeo. And if you are captured by the simple beauty of this plant, you might also like a[…]

In Development, Vol 137 (Issue 14)

Posted by on June 23rd, 2010

Here are the research highlights from the current issue of Development. You can find these on the Development site but we thought it would be useful to have them posted on the Node, too. Brainy signals for actin dynamics During brain development, neurite outgrowth and neuronal migration establish the brain architecture needed for brain function.[…]

Developing science in a far country: the paradoxes of life …

Posted by on June 16th, 2010

I am from Chile, a country located along the extreme southwestern coast of South America, a beautiful land of happy and courageous people, with an admirable geography however from time to time, some naturally events remind us how small is  our human scale compared with the Mother Earth that gave us life, (“we are children of[…]

Yes, incredible in every way with its friendly people, deep-rooted culture, heritage and history, natural beauty and scientific accomplishments, the most recent being in the area of space research[…]

March of Dimes award for Shinya Yamanaka

Posted by on May 19th, 2010

Earlier this month, Shinya Yamanaka, of the Gladstone Institute of Cardiovascular Disease in San Francisco, won the March of Dimes Prize in Developmental Biology for his groundbreaking work on induced pluripotent stem cells (iPS cells). Yamanaka was the first to generate iPS cells from somatic cells – first from mouse fibroblasts and later from human[…]
