🎉Last Friday, we celebrated #25yearsICREA: a research community that has transformed the Catalan scientific landscape through the Catalan Government's commitment and a joint endeavor with universities & research centers.

A shared success that projects Catalonia into the future!

Yesterday we kicked off “The World in One Line – Schrödinger’s Equation Turns 100” and yes, there was cake 🎂 We even sang Happy Birthday! 🥳

Magnetotactic bacteria optimally navigate natural pore networks Diverse magnetotactic bacteria are adapted to the local geomagnetic field and grain size to maximize their swimming speed through the pore space.

Magnetotactic bacteria swim along geomagnetic field lines to navigate sediments. Using microfluidics and simulations, this study shows their motility is optimised, revealing how evolution fine-tunes life for challenging environments.

Inside arXiv—the Most Transformative Platform in All of Science Modern science wouldn’t exist without the online research repository known as arXiv. Three decades in, its creator still can’t let it go.

Academia is cool because if you're doing it right, every paper you published in the last 3 years feels inadequate now that you understand the topic better, but it'll take 3 years to get out the version where you get it more right, and you get to do that until one day you die! Isn't that cool

Calculating a Phase Diagram of a Simple Water Model Using Unsupervised Machine Learning on Simulation Data We use unsupervised machine learning to construct a phase diagram of a simple 2D rose water model. The machine learning method that we use is a combination of dimensionality reduction methods and clustering algorithms. Two different data sets from the same simulations are used as input data for machine learning. These are angular distribution functions and a set of different thermodynamic, dynamic, and structural properties. To evaluate the efficiency of the method, the machine learning results are compared to manually determined phase diagrams. We show that the methods successfully predict the phase diagram of the rose water model. Furthermore, the phase diagrams obtained from the two data sets are in semiquantitative agreement with each other. Four different solid phases, one liquid phase, and one gaseous phase were determined. The method we have presented is straightforward and easy to implement. It requires almost no prior knowledge of the system to obtain a phase diagram. The method can also be used to distinguish between the different parts of the same phase that have different properties or a sufficiently different structure, and in this way find local differences and anomalies.

bioRxiv has partnered with Sciencecast to produce lay summaries of posted preprints. Truly impressive.

Here our paper on integrated 3D tissue mapping and nuclear morphology is well summarized and properly placed in the larger context of the field.

HISTORY OF PHYSICS

Kenneth G. Wilson. A revolutionary.
(June 8,1936 - June 15, 2013)

Wilson was a markedly independent and original thinker as well as being a rather private and reserved person. An important part of his youthful look was that when somebody said something that

This sounds great. Also, what a lot of questions visualizations like this raise. Don't you think, @bnerlich.bsky.social?

There could not be a better time for a massive Canadian government investment in science. We need:
- a doubling of the science budget
- a 5 year tax holiday for any major US tech company moving to Canada
- major incentives for Canadian private sector $ to invest in tech

El 10 de desembre de 2007 el Consell General dels Pirineus Orientals aprovà l'oficialitat del català amb el francès.

Al mateix document, el terme «Catalunya Nord» es formalitzà com a equivalent del francès «Pyrénées-Orientales».

És, doncs, un nom neutre i oficial.

Are complex systems predictable? Can we use (un)predictability to measure complexity? Here's a great review by A. Vulpiani and co-workers on how chaos, Lyapunov exponents, information theory and statistical physics get together to answer these questions denali.phys.uniroma1.it/~cencini/Pap...

The Nazis and us The Holocaust continues to haunt our politics. But slurring our opponents as Hitlers is not the way to defeat them.

Here's Marr's piece. He's right that we shouldn't make idle accusations of Nazism. But equally, it's unhelpful to say e.g. "They can't be Nazis because they haven't invaded Poland." The important point is to recognize the same warning signs and strategies.

I si la singularitat catalana fos donar més protagonisme a les ciències i apostar per un batxillerat sòlid, amb hores suficients per formar futurs científics i científiques? Necessitem reforçar, no retallar. La ciència és el motor del futur.

How do we approach the complexity of life as a nonequilibrium system? Using physics and, in particular, landscape and flux theory, many systems, from cells to ecology and cancer, can be adequately represented and modelled. Check this paper in Reviews of Modern Physics

Initiation of epithelial wound closure by an active instability at the purse string The ability of biological systems to withstand and recover from various disruptions, such as spontaneous genetic mutations and environmental damage, largely relies on intricate feedback mechanisms. We theoretically study the mechanical response of an epithelial tissue facing damage in the form of a circular wound. Our model describes a feedback loop between the generation of active forces in the actomyosin and tissue mechanics, described by the vertex model. While the exact dynamics of wound closure may be influenced by several biophysical mechanisms that interplay in a nontrivial way, our findings suggest that the closure may initiate as an active instability, triggered by a reduced myosin turnover rate at the wound’s perimeter.

New study models epithelial wound closure using an active vertex model, showing that epithelia may initiate the closure process through mechanical instability. Read more to find out how myosin dynamics and tissue mechanics drive this self-repair process. ow.ly/u0f250UBiLt

@standehaene.bsky.social. It is a fantastic tour of evolution, culture, and neuroscience.
