"Today, that weed [Arabidopsis thaliana] is widely regarded as a botanical superstar. Arabidopsis has been the focus of some 100,000 research papers. Its seeds have flown around the Moon; it is the go-to plant for experiments on the International Space Station. And when the scientific community decided which plant should be the first to have its genome sequenced, Arabidopsis emerged as the winner."

"Zebrafish exposed to light pollution at night showed signs of anxiety, such as swimming less and staying close to aquarium walls. The next generation of zebrafish also showed anxiety-related behaviors, even without direct exposure to the light, suggesting lasting effects across generations."

There was someone, like 10 years ago set up a biotech in California that was focused on making known patient mutations in really simple, highly reproductive model organisms (yeast, fly, worm), and then testing a variety of compounds to see if they resulted in the rescue phenotype.

I know they concentrated on lipid processing mutations initially.

I was describing this to someone, and could not remember the name of the person or company.

A French study in a #ModelOrganism found that:

1. Acute exposure to 500-lux artificial light at night alters the expression of #genes in retinal cells involved in signaling pathways linked to cellular stress and inflammation;

2. Chronic exposure to #ALAN causes changes in both scotopic and photopic retinal sensitivity; and

3. ALAN exposure "impairs visual function in the long term, linked to retinal degeneration "which can lead to #vision loss."

New results in a mouse model "demonstrate the rapid and potent effects of [artificial light at night] on cerebrovascular networks, highlighting the importance of ALAN mitigation in the context of health and cerebrovascular disease."

A new transparent #killifish line called klara, generated using #CRISPR/Cas9, can significantly simplify explorations of #development, #senescence, ageing and #regeneration. #ModelOrganism https://elifesciences.org/articles/81549?utm_source=mastodon&utm_medium=social&utm_campaign=organic

#Introduction:

Hello #ScienceMastodon.

My name is Verena Kohler and I am a #FirstGen #scientist, currently working as independent senior #postdoc at #UniGraz in Austria.

I am interested, how age influences #proteostasis, the balance between protein production, folding and degradation, and how #ageing affects cellular #communication routes.
For that, I am using my favourite #ModelOrganism, the baker’s #yeast, a lot of #FluorescenceMicroscopy and #HighThroughput screens.

Let’s talk #science !

OK, #Introduction … Take 2

I’m a microbial geneticist interested in how microbes live everywhere, with everyone! Venturing outside our fave #lab #modelorganism #ecoli k12 lately to study #wildmicrobes of the gut
