3D mini-brain sheds light on Zika Virus in the brain

Posted by on June 10th, 2016

The Zika virus is making headlines as a major world health crisis linked to a host of neurological conditions. In the cases of microcephaly and Guillain-Barre, the evidence that Zika Virus is the root of the condition is strong enough to be considered causal. Babies born to infected mothers often have microcephaly, a condition that manifests[…]

Cellular conversations

Posted by on June 7th, 2016

We know that cells are the building blocks of our bodies. But they are not like inert wooden blocks. They are complicated tiny machines that communicate with each other to make sure that the many simultaneously occurring processes in our bodies are in order. Stem cells participate in many of these cellular conversations, and a[…]

Visualizing our ‘gut instinct’

Posted by on May 19th, 2016

How on earth do we turn into a living, breathing, singing, speaking being, from just the fusion of two cells? Development is fascinating and mysterious. Stem cells are one component of how this intricate process unfolds, allowing the embryo to not have every type of cell from the start. Imagine if the only way our[…]

New Node banners!

Posted by on May 6th, 2016

As you may have noticed, we have a series of new Node banners (alongside some of our old favourites). As there isn’t really space to give credit to the authors on the banner itself, we thought we would write this short post to give credit where credit is due! Below is the list of the[…]

New 3D anatomy viewer available at eMouseAtlas

Posted by on January 26th, 2016

A new 3D viewer that allows interactive visualisation of mouse embryo anatomy is now available from the eMouseAtlas website (www.emouseatlas.org/). A slice viewer allows visualisation of anatomy on arbitrary section through mouse embryos – much like a virtual microtome – whilst a 3D anatomy pop-up window allows users to visualise the delineated anatomical components in[…]

Drawing Embryos, Seeing Development

Posted by on January 25th, 2016

  Today, when we want to capture an image given by the microscope we can either snap a photograph of it or obtain a computer-generated image. But prior to when photographic methods began making their way into biology labs and journals, this meant you had to draw it. For embryologists, this meant creating accurate, detailed[…]

Making and re-making the brain

Posted by on December 23rd, 2015

  The three-pound lump under our skulls that allows us to speak, run and function in our daily lives is a mass of dozens of types of minuscule cells joined in an intricate web of communication. We pop out of the womb with our brains ready for us to interact with the world, but throughout[…]

The Node’s DevBio Quiz!

Posted by on December 17th, 2015

How well do you know your developmental biology images? Can you tell your frogs from your flies and your limbs from your antennae? Here at the Node we’ve come up with a quiz to find out!   It’s very easy: we’ve collected a few images of embryonic structures, and all you have to do is[…]

Organ Design 101: Discovering the rules for building a pancreas

Posted by on November 19th, 2015

As we develop from wads of cells to fully formed humans, each of our organs goes through intricate processes to achieve the right combination and number of cells arranged in the proper way. Research published in PLoS Biology by Yung Hae Kim and her colleagues looks at the development of our hormone-oozing pancreas, which assists[…]
