“Scientists seek the unknown, and we construct what does not yet exist.” – Filipe Carvalho, Head of the Scientific Hardware Platform.

The Scientific Hardware Platform is in charge of designing and producing unique, ultra-precise mechano-electronic devices. Without them, the neuroscientists working in the Champalimaud Centre for the Unknown would face bigger challenges to carry out many of their experiments.

The faculty of Champalimaud Research are deeply troubled by recent reports of scientists stranded abroad due to the recent US travel restrictions for citizens of Iran, Iraq, Somalia, Yemen, Syria, Libya, and Sudan. We encourage scientists affected by this order who may be stranded in Europe to contact us. We will make every effort to accommodate your needs here at the Champalimaud Centre for the Unknown in Lisbon, Portugal.

A mere fortnight had passed since the inauguration of Donald Trump as the President of the United States, a short period that has sent shock waves throughout the world. Whether you are a supporter or not, the fact is that Trump is a controversial leader whose presidency will have implications into many fields, both nationally and abroad.

In the [animal] motor cortex, activity is highly variable at the beginning [of motor learning] and then becomes consistent, not so variable – it crystallizes. So Vivek [Athalye] wanted to know: “Can we devise a way to see how the brain does this?” – Rui Costa.

Watching the smooth movement generated by hundreds of fish as they swim in unison is truly mesmerising. But it’s not only its sheer beauty that makes it so hard to look away, for scientists, it’s also the fact that its emergence is so difficult to explain.

A surprising behavioral effect, discovered in mice by neuroscientists at the Champalimaud Centre for the Unknown (CCU), in Lisbon, Portugal, strongly suggests that serotonin is involved in a biological mechanism which affects the animals’ motivation.

Who are today’s scientists? Inspired by the project “Humans of New York”, Ar Magazine turns the spotlight on individual humans of science every month.

We are constantly being exposed to mixtures of scents. But, as incredible as it may seem, we are pretty good at separating them from each other. Our brains accomplish this many times a day with no apparent effort, but little is known about the way they do it. Now, Zach Mainen from the Champalimaud Centre for the Unknown and colleagues from other countries have, for the first time, come up with computer program that can do it.

Is there diet that is healthier than all others? This question has proven difficult to answer. Now, a new study by scientists at the Behavior and Metabolism Lab, and colleagues working in other countries, suggests that genomics is the key to optimizing the protein composition of a diet.

Serotonin, one of the major chemical messengers serving neuronal communication, is usually associated with the direct regulation of affective states and mood in general. But growing evidence suggests that one of the core functions of this neurotransmitter may be to facilitate our adaptation to changes in the world around us – which, in turn, may indirectly impact mood.
