#geneticist — Public Fediverse posts

Some #snakes lack the ‘#hunger #hormone.’ Experts are hungry to know why
The #gene for #ghrelin is missing in serpents, yet present in other fasting #reptiles
Evolutionary #geneticist Rui Pinto and colleagues stumbled on the discovery when comparing the #genomes of 112 reptile species, including snakes, crocodiles and chameleons, which they obtained from public database. Genes for ghrelin and its activating enzyme were absent in 32 snake species.

David Suzuki, a #geneticist and #climate activist, explains the shortcomings of conventional #economics and how they are a form of brain damage. From 2011 documentary "Surviving Progress"

Saw the short sentence, "Genetics happens randomly."

Any #Geneticist / #Biologist like to comment?

Joseph Lee: #Geneticist Krystal Tsosie advocates for Indigenous data sovereignty: A member of the #Navajo Nation, she cofounded the Native BioData Consortium

"Krystal Tsosie grew up playing in the wide expanse of the Navajo Nation, scrambling up sandstone rocks & hiking in canyons in Northern Arizona. But after her father started working as a power plant operator at the Phoenix Indian Medical Center, the family moved to the city. “That upbringing in a lower socioeconomic household in West Phoenix really made me think about what it meant to be a good advocate for my people and my community,” says Tsosie, who like other Navajo people refers to herself as Diné. Today, she’s a geneticist-bioethicist at Arizona State University in Tempe. The challenges of urban life for Tsosie’s family and others, plus the distance from the Navajo Nation, helped spark the deep sense of community responsibility that has become the foundation of her work."

A Multitalented Scientist Seeks the Origins of Multicellularity https://www.quantamagazine.org/a-multitalented-scientist-seeks-the-origins-of-multicellularity-20240221/

"The #geneticist Cassandra Extavour became the first Black woman to receive tenure in the biological sciences at #Harvard University’s Faculty of Arts and Sciences. Her studies of reproductive cells yield insights into the origins of #multicellularity."

@ngaylinn Not a #Geneticist but I’d say:

o if you start from a stem cell, in theory its complete behaviour once matured can be defined by its DNA

o once mature… I don’t know if you could replace the entire DNA, and the cell would already have expressed all the proteins that its previous genome encoded so it would be differentiated. But I think the proteins that read and turn DNA into RNA then proteins are the same for all cells right? So it might at least partially work? Haven’t heard of this though.

o you can definitely insert some new DNA into a cell’s existing DNA - that’s how #Optogenetics work for example. And this works for already differentiated neurons. But it only adds a small functionality - doesn’t completely change the way the cell works.

Please, if someone knows better, don’t hesitate to correct me!

#January 26, 1943
#OTD Nikolai Vavilov, Russian #Botanist & #Plant #Geneticist, died of starvation at the Saratov concentration camp.

Meanwhile, Nikolai's team of scientists were held up inside the Russian #SeedBank, saving the precious repository from the 900-day siege of #StPetersburg. Placing the security of the world's seeds (some edible) over their own survival, some valiant #Botanists starved to death.

Today the seed bank honors Niko as the Vavilov Institute of Plant Genetic Resources.

Excavating genomes:

In which (paleo-) #geneticist and Nobel Laureate Svante #Pääbo recounts how with his research he brought future into the past - and why #Neanderthals are not really extinct at all.

Great @[email protected] interview by @[email protected] here: https://www.theguardian.com/science/2023/jan/12/svante-paabo-interview-nobel-prize

Today, January 6 is National #Bean Day! Why Jan. 6? For some (https://www.daysoftheyear.com/days/bean-day/), "The day commemorates the death of the #geneticist Gregor Mendel, whose experiments with breeding pea [and bean] plants formed the basis of modern genetics. " (1/2)

Found my current study organisms in the aquarium.
Everyone, say hello to Acropora spp.!
More pictures coming to research slides for the next 3+ years.

#Introduction #Hello Tooterverse! I’m Ian, a #Geneticist in beautiful #Vancouver. Whether the #twexit 🐦 turns out to be an actual thing or just blows over like Y2K, I thought I’d wander over here for a new experience.

My interests are all things #cancer #MolecularBiology #Genetics #Genomics #LaboratoryMedicine #Bioinformatics and #ClinicalResearch. I dabble in #Photography and I spend a lot of time freezing and wet on the side of a #Soccer pitch.
