I created a free #K12 interactive #science quiz for #students to discover which Order a Mammal belongs to. If you'd like to beta test it and let me know if you find glitches, I'd appreciate it. I've stared at the screen for too long and am no longer seeing the branching questions objectively. The plugin limits me to a max of 25 categories, so I had to get creative. TIA for the feedback. https://handinhandhomeschool.com/teaching/science/mammal-quiz/
What do other people with training in #genetics or #molecularBiology think of the use of #DNA as a metaphor? I've always found it super irritating, but maybe other scientists love it?
For example, I'm now seeing it used in the context of social movement organizing and find this kind of usage very distracting, even though the concept they're trying to describe probably makes a lot of sense.
You've probably heard from transphobes about how "you can't change your DNA," so nothing you do in transition really matters. "Basic biology," they whinge. Well... what about intermediate biology?
This week on #StainedGlassWoman, come and see How HRT Rewrites Your DNA by just plain turning off the parts you don't need and turning on the ones you do! Now with more wedding photos, from another queer wedding.
Interesting fact of the day... single cellular organisms have "Molecular Motors" in them.. basically the quantum mechanical equivalent of a mechanical motor... They are surprisingly similar in appearance and are just super cool!
To produce plant-based cheeses that feel and taste like dairy cheese, scientists have their sights set on fermentation. In a new research result, University of Copenhagen scientists demonstrate the potential of fermentation for producing climate-friendly cheeses that people want to eat.
Before epilepsy was understood to be a neurological condition, people believed it was caused by the moon, or by phlegm in the brain. They condemned seizures as evidence of witchcraft or demonic possession, and killed or castrated sufferers to prevent them from passing tainted blood to a new generation.
I understand that not self-fertilizing is an adaptive benefit for plants (& all living organisms) but I don't have a scenario that shows how the benefit works.
Given a population w/genetic variations some tiny percentage of which are beneficial in the habitat, why is it such a huge boost to survival to mix your genes?
It is precisely because beneficial adaptations are rare? If beneficial mutations were common would self cloning and fertilizing. be more common? #question#biology#evolution
"Duke University has decided to close its herbarium, a collection of 825,000 specimens of plants, fungi and algae that was established more than a century ago. The collection, one of the largest and most diverse in the country, has helped scientists map the diversity of plant life and chronicle the impact of humans on the environment.
The university’s decision has left researchers reeling."
anyone know of good online resources for finding traits of bacteria? Ideally a database or large csv file where a bunch of species of bacteria have traits listed such as Gram stain, aerobic needs, etc, but I'll settle for any resources that have consistent information about bacteria.
Wikipedia, for example, hasn't been very consistent in what information it shows for species. #microbiology#biology#bacteria#resourceRequest

I've started drinking coffee relatively late, and have a love-hate relationship with it. Sometimes I happily quit drinking coffee for a while, and sometimes I feel so tired that I really need a coffee energy boost to get things done, even though it's a temporary adrenaline boost with drawbacks.
Lately I'm drinking more green tea to curb my caffeine intake.
Can I get some follow recommendations? I’m acutely aware that of the people I follow who post about our planet’s systems, most of them are climate people. I’d love to follow more people posting at a #systems level. Y’know, the people who distill down expert knowledge into consumable packets for the rest of us. Think #hydrology/ #freshwater/ #oceans, #biodiversity, #ecology, #biology, #agriculture, #energy, #economics, #geology#planetaryBoundaries … these kind of topics. Boosts appreciated!
Jaguar attacks on pets and farm animals are a common problem, but after developing a drug-induced stomach ache, the big cats seem to learn not to kill certain animals
Last month, a unknown molecular biologist claimed to have worked on alien DNA at the Battelle National Biodefense Institute. They posted an incredibly detailed breakdown of their work on r/aliens, then disappeared. (old.reddit.com)
First off, the link above to the bad place is for reference - no need to visit - full text below....

Ancient technology turns plant-based cheese into 'something we want to eat' (phys.org)
To produce plant-based cheeses that feel and taste like dairy cheese, scientists have their sights set on fermentation. In a new research result, University of Copenhagen scientists demonstrate the potential of fermentation for producing climate-friendly cheeses that people want to eat.
Scientist, after decades of study, concludes: We don't have free will (phys.org)
