Serotonergic Control of Spine Morphology During Growth in Zebrafish
Scoliosis is a three-dimensional deformity of the vertebral column that commonly emerges during growth, yet the biological mechanisms that initiate and drive curve progression remain poorly understood...

How is proliferation modulated in regeneration for tissues to reach their right size? We found that, in zebrafish scales, proliferation is shut down by a moving front of osteoblast maturation. The front's dynamics scale with tissue size, ensuring proper osteoblast amplification. tinyurl.com/5e45twx3

Successful regeneration recovers lost tissues to their original form. Here, we investigate how proliferation of bone-forming osteoblasts is timely regulated to control tissue size during zebrafish sca...

I walked past a group of students running a stall to raise awareness about library closures and ways to support libraries. Mixed emotions. Sad that they have to fight for this, but deeply inspired by their passion.

Today, I saw daybreak twice. On a short flight I saw the sun come up; a beautiful orange sky. Then we descended and the sun disappeared. The stars came back out. I was at the gate waiting for my next flight when I saw daybreak number 2. I guess the earth really is round!

I'm a soccer fan (Arsenal). Recently, the Premier League ran an anti-homophobia campaign where captains wore rainbow armbands. Some refused or altered the message. A common response from fans has been "keep politics out of football [soccer]". Let's unpack why this isn't a serious argument. (1/6)

There is a human tissue that builds itself up and breaks itself down every 28 days (on average) using non-scarring wound healing and instead of studying that and learning everything we can about it we think it's gross and look for other less relevant models to understand wound healing.

Scoliosis is a common condition in which the spine curves to the side and rotates, often onsetting during adolescence. In our lab, we generate zebrafish with scoliosis-like spinal curves to try to understand the causes of this disease.

Arturo Rosenblueth was a pioneer of cybernetics and, along with Norbert Wiener, had this to say: "The price of metaphor is eternal vigilance". Let's remember that metaphors are useful for thinking and discussing science, but they are not reality.

Random thought: Playing a game, one person says a word and the next person makes a new word by changing only a single letter: E.g. Rain — Raid — Paid — Pain — Gain — Grin — Grit — etc. Can all 4-letter words in the dictionary be connected like this? Do some miss out? How many?

12 asymmetric animals, bonus number 13: the Dahu The Dahu is a goat-like creature from Southern France. Amazingly, Dahu legs on one side (either left or right) are longer than its legs on the other side… this means the Dahu can only walk around mountains in one direction!

12 asymmetric animals, day 5: fiddler crabs Male fiddler crabs have a large 'major' claw and a small 'minor' claw. The major claw is used for display signals and fighting. If a fiddler crab loses its major claw, it will grow a new one on the opposite side.

12 asymmetric animals, day 4: flatfish Flatfish have both eyes on one side of their head. Eyes begin in the normal place, then one migrates around the skull to join the other Some species have all left-sided eyes, others all right-sided while some show left/right randomization.

12 asymmetric animals, day 3: the wrybill. Another example from the world of birds, this New Zealand plover has an asymmetric beak which is bent sideways to the right. This is a directional asymmetry because all individuals of the species have a right-sided beak.

12 asymmetric animals, day 2: red crossbill. Red crossbills have asymmetric beaks in which the upper and lower mandibles cross each other such that the lower mandible sits to the left or right of the upper. The direction is random and so is referred to as an anti-symmetry.

12 asymmetric animals, day 1: the narwhal. Narwhals of the polar oceans have a large tusk. But it is not centrally located on their head; it grows from the left side. It is a modified upper left tooth that erupts through the lip and extends several feet. A curious canine!
