The circumstances of our lives have cast us into a rigid mold that keeps us on a blind steady trajectory. We can change but we are in our molds, doing the same to satisfy anyone but us. That's my favourite performance. @coldplay @richardashcroft 🌎🌍🌏 youtu.be/SbFqIRSX6js

Do we grow wiser as we age? Can we? I spent over 15 years chasing glam journals and wasted a lot of time and energy (and this chase caused a lot of frustration to my team and co-authors). I don’t want to wake up at 70 and realize my life went into convincing a few editors my work was trendy enough. Enough is enough. I'll try to be smarter.

Apostei 200 estalecas com Lucas Calvacante que o @vinijr faz dois gols ou mais na Copa do Mundo. Eu boto tanta fé no Vini na Copa que chuto que a chance de eu perder esta aposta é quase nula -- talvez seja caracterizado como estelionato ganhar dinheiro fácil demais.

I think I’ll start posting about the lessons I’m learning as part of this new thing I’ve been doing (my attempt to change the landscape of scientific publishing and consequently how science is done) One lesson I’ve learned (and also unlearned…) is that it’s very convenient to put all the blame on journals. I’ve done it myself for years. And yes, many of the criticisms are valid. They make way too much money at our expense and are often not very good at distinguishing good science from bad science. Some of them (not all of them! There are good journals too!) bring very little value and can even slow scientific progress. They can be inefficient and biased, and journal names are a very poor substitute for quality. But the more I work on this, the harder it is for me to believe that journals are the only problem (even specifically when it comes just to publishing science). Universities are equally at fault. And I don’t just mean that we, the scientists doing the reviewing, are part of the problem (which we are, obviously). I mean the institutions we belong to, and the way they make decisions. Hiring, promotions, funding allocation - these processes are often opaque, subjective, and not particularly scientific. They are slow, inefficient, and they rely on journal brands as a shortcut. I used to think journals were driving this, but it’s obviously more like a loop. Journals could not stay the way they are if universities changed how they evaluate quality, because they would lose much of their justification to exist. But universities do not evaluate science directly, because there is too much of it and not enough experts available and time (or money to pay reviewers). So they rely on journal prestige, while journals rely on institutional reputation. Where you do your science ends up mattering more than what you discover, and this affects publication, which affects funding, which determines whether you can even pursue your ideas. This can be exploited, of course, but I don’t think institutions (or the responsible faculty/management) behave this way because they are evil or greedy. They do it because evaluating science properly is ridiculously hard and time-consuming, and the system does not reward doing it well. But the important question is can we change the way our universities work, or is it an impossible task? What I've learned working on this problem is that we can. In addition to engaging with management we can influence the system in other ways. In many cases we don’t need their approval. We are the ones who form the committees. I believe we can break the loop, if we target the mechanism of science evaluation. Journals will keep their power, shortcuts will keep dominating, and the same biases will keep reproducing themselves unless we change how we evaluate science (how we do review). If we can find ways to critically evaluate science at scale, rigorously and transparently, we can change how decisions are made.

Petunia hybrida has been bred into an incredible diversity of colors and patterns. Most arise from mutations in the anthocyanin pathway or post-transcriptional gene silencing that turns pigment genes on and off 🧬🎨

If you could do a sabbatical in any lab to recharge your energy and get excited again about a totally different field in biology (different from what you are studying), where would you go?
