Bruno Costa-Silva receives EMBO Installation Grant

EMBO announces today (December 18, 2017) seven life scientists as recipients of EMBO Installation Grants. These grants will support the early-career researchers in establishing their independent laboratories in the Czech Republic, Estonia, Poland, Portugal and Turkey.

Bruno Costa-Silva, head of CR’s Systems Oncology lab, was one of the seven awardees. His project will study the association of Exosome populations with liver metastasis.

Scientists reveal the “Lego pieces” that form complex zebrafish movements

Motor behavior could be formed from a range of continuous possible movements. But it could also be constituted by sequences of distinct, discrete movement types. New results suggest that the latter is the case, at least for zebrafish larvae.

Much like music is made of notes, the complex behaviors of zebrafish larvae, such as hunting or social interactions, are formed from a small set of movements types arranged in specific sequences.João Marques

Life of PI: A neuroscientist with a passion for the mathematics of things

From chemistry to physics to neuroscience, from Spain to the United Kingdom, back to Spain again and then to Portugal, Gonzalo de Polavieja’s career has certainly had more than a twist. Since 2014, he is the principal investigator, or PI, of the Collective Behavior Lab at the Champalimaud Centre for the Unknown, in Lisbon.

Body movements just need a “puff” of dopamine to get started

A new study in mice suggests that a burst of activity in dopamine-producing neurons, just at the beginning of a movement only, as opposed to all the time, is all it takes for a movement to unfold correctly. This may have important implications for treating Parkinson’s disease, which is caused by the death of the neurons that make dopamine.

Fruit fly hunger games: taste neurons in control

Right at the tip of the fruit fly’s tongue sit two sets of taste neurons that have now been found to be crucial for the insect to develop a craving for protein.

The first set makes the fly start to eat yeast, telling it it is the right food, and the second set tells it to keep on eating it, that yeast is still the right food. -Carlos Ribeiro

Life of PI: Hooked on motor behavior, including her own

Eugenia Chiappe is so fascinated by the way living organisms manage to evaluate their own movements, so as to be able to flawlessly perform complex motor tasks, that in trying to understand it she has led a sort of double life, divided between science and the performing arts.

I am very happy here [at Champalimaud]. There are a lot of young people, we discuss science all the time; and we are all working on the same problem, but each from a different angle.Eugenia Chiappe

In pursuit of pleasure, the brain learns to hit the repeat button

In a scientific first, researchers have observed in mice how the brain learns to repeat patterns of neural activity that elicit the all-important feel-good sensation. Until today, the brain mechanisms that guide this type of learning had not been measured directly.

Serotonin promotes perseverance

It was thought that the neurotransmitter serotonin most likely acted by inhibiting behavior. Now, scientists at the Champalimaud Centre for the Unknown have shown that general idea to be wrong.

We had never seen an active behavior promoted by serotonin. This is, to my knowledge, the first time such a behavior has been observed when serotonin-producing neurons are activated. – Eran Lottem
