Scientists Just Discovered an RNA That Repairs DNA Damage – It's a Game-Changer
‘I think we brought the wrong one home’: one mother’s search to find her lost son
Joan always suspected she had been handed someone else’s baby by the hospital when she gave birth more than 70 years ago. Then an Ancestry DNA test seemed to prove her right. Now in her 90s, she is in a race against time. Can she find her missing child?
Visualizing #cells after editing specific #genes can help scientists learn new details about the function of those genes. But using microscopy to do this at scale can be challenging, particularly when studying thousands of genes at a time.

Ever since scientists discovered that most people on Earth have a small slice of Neanderthal in their DNA, they have been trying to figure out when and how it got there. Now, two research groups say humans interbred with Neanderthals for a limited period about 50,000 years ago as our ancient ancestors migrated out of Africa. But why did Neanderthals die out while humans survived? Read more from @NBCNews.
The Knowledge Gene: The Incredible Story of the Supergene That Gives Us Human Creativity by Lynne Kelly, 2024

Water Quality and AMR 
The effects of climate change on water systems are multifaceted:
• Increased #runoff and #flooding contribute to the dissemination of #contaminants.
• Alterations in #aquatic #ecosystems may favour the proliferation of specific #bacterial populations.
• #Wastewater treatment facilities encounter significant challenges.
• #Microplastics may function as #vectors for the transmission of #AMR #genes.

And this is critically important, because #Dupuytrens is considered genetic, although AFAIK the precise gene has not yet been identified.
This condition is also sometimes called #VikingsDisease, as it most commonly effects people from or descended from #Scandinavia and northern European regions such as the #Netherlands.
And that fits my elder's history perfectly.

‘The #KKK Thought the Same’: #ConvictedFelon #DonaldTrump Hit with #Accusations of Scientific #Racism After Suggesting Certain People Will Commit #Murder Because ‘It’s In Their #Genes’
“Let me guess…the #immigrants coming from #Europe don’t have the ‘#badgenes,” one X user wrote. “The #KKK thought the same about #black #people during #JimCrow and beyond,” someone else added.

In 1910, Thomas Hunt Morgan showed that genes, the discrete units of inheritance, reside on chromosomes. #Poetry #Science #History #Genetics #Genes #Chromosomes #Morgan (https://sharpgiving.com/thebookofscience/items/p1910b.html)
"The 2024 Nobel Prize in Physiology or Medicine was awarded on Monday to U.S. scientists Victor Ambros and Gary Ruvkun for the discovery of microRNA, a molecule that performs this important regulatory process."
Mean Genes: From Sex to Money to Food: Taming Our Primal Instincts by Terry Burnham, 2000
Short, sassy, and bold, Mean Genes uses a Darwinian lens to examine the issues that most deeply affect our lives: body image, money, addiction, violence, and the endless search for happiness, love, and fidelity.

Found in a 2016 entry in my journal:
Stephen Pinker's favorite example of two identical twins separated at birth:
- One raised by a Catholic, Nazi family in Germany
- One raised by a Jewish family in Trinidad
- Upon entering a Minnesota lab, both
- were wearing navy blue shirts with epaulets
- liked to dip buttered toast in coffee
- wore rubber bands around their wrists
- liked to sneeze in elevators, surprising those who were sharing an elevator with them.
