Lots of CPU glue in use, getting new processors with more cores. Thanks so much @SDF for your commitment to the .

Bonus: spot the Easter egg.

Hello Folks! Just a quick update, we're continuing to make progress in our staging that will allow us to spin up additional processors hopefully as...

Hey science journalists, we've got two 12-month (parental cover) reporter positions open with Nature in London - more info & application at careers.springernature.com/job

The wave remains strong. What a week.

#Introduction:
I am a climate scientist with interests in better understanding historical changes in climate and extreme weather. Also think about future climate-related risks, among other topics: edhawkins.org

One key approach in this research is using citizen science to recover millions of lost weather observations, such as: WeatherRescue.org

I dabble in climate dataviz too, including the Climate Stripes: ShowYourStripes.info

All scientists are often wrong. The advantage of youth is that you are not stuck in fixed ways of thinking about things, as can happen when you get older.

Playing god with : "An explanation for unexpected population crashes in a constant environment" by Johnson et al. 2022 onlinelibrary.wiley.com/doi/fu

"Most of the time, populations can be described as fluctuating randomly around a weakly-stable equilibrium. However, some populations experience unexpected population crashes... ecological events. These crashes, however rare, have outsized consequences for conservation and management"

"we use mechanistic models and flour microcosm experiments to derive a novel mechanism of population crashes... can occur when stochasticity occasionally ‘pushes’ population density into a regime where overcrowding is severe."

Curiously: "Obviously, only females can oviposit. Less obviously, females are far more voracious egg cannibals than males—using industrial die to perform an egg mark-recapture experiment, Sonleitner (1961) found that castaneum females ate 19 times as many eggs as males."

There's even an #iNaturalist project collecting out of season bees

... which includes this observation of an Andrena cineraria mining from the Cambridge Botanic gardens inaturalist.org/observations/1

Meet the Silver-studded Blue (Plebejus argus). This butterfly has an incredible relationship with ants!

As a caterpillar, it attracts ants by producing sugary liquid & amino acids from a special gland & pores. In return, the ants look after the caterpillar, protecting it from predators & even allowing it to shelter inside their nest. The caterpillar pupates inside or near to the nest, with a protective swarm of ants surrounding the newly emerged butterfly until its wings have fully expanded.

Hello People!

I am a Post-doc wrapping up its PhD at the Max-Plank Institute for Cell Biology and Genetics. I am currently working on , studying liver architecture establishment during mouse .

I mainly use microscopy and cell culture to understand how cells establish their polarity and contribute to overall tissue organization. I'm interested in and always looking forward to learning more on this topic.

We recently found lower blood oxygenation and #neurovascular function in the #hippocampus compared to #neocortex, which might explain why the hippocampus is sensitive to hypoxia and affected early in Alzheimer’s disease: nature.com/articles/s41467-021. 2/4

Hey people! Time for an #introduction! I lead a research group at the University of Sussex, UK. I’m interested in how the #brain controls its #blood flow, and what happens in the brain when there is a slight disruption in this energy supply, as happens before people develop symptoms of Alzheimer’s disease. We image neurons, glia and blood vessels in mouse brain to try to understand what they do in different situations and when they go wrong. 1/4

Hi, this is Greta. You are welcome to follow me here, if you prefer planet earth to planet mars.

A reminder for anyone new to mastodon who might not be happy with some of the racist and bad actors out there on other servers... Just import the fediblock list to your personal blocks and you will be safe from the vast majority of bad actors.

𝑺𝑻𝑶𝑹𝑴⛈️  
I took all the domains from https://fediblock.neocities.org/ block list and put it in a csv file that can be imported so you can block all hateful ...

Hello people! time: I’m a post doc at Salk institute studying and . I am from Arizona and did my PhD at Harvard studying and .

In addition to my research, I care about mentoring and am active in Salk’s SACNAS chapter. I’m also a runner training for my first marathon and have two really good cats.
Here’s my website: krissylyon.wixsite.com/website.

Mastodon growing pains... switched servers and my #introduction is gone, so let me try again, this time with hashtags!

My #cognitiveneuroscience lab studies #learning, #memory, and #sleep using empirical as well as #computationalmodeling approaches.

(Did I do it right?)

My optimism about Mastodon has been oscillating at high amplitude and frequency, but my fingers are tightly crossed that we will be able to rebuild our science community here!

Can confirm, qoto.org instance runs very snappy, despite (goodness!) 1000 new users a day!

🎓 Dr. Freemo :jpf: 🇳🇱  
@worldsendless We are seeing 1000 new users a day at the moment. And yea still operating smoothly.
