A genetic analysis hints at why COVID-19 can mess with smell. A study of nearly 70,000 adults with COVID-19 found that individuals with certain genetic tweaks on chromosome 4 were 11 percent more likely to lose the ability to smell or taste than people without the changes. sciencenews.org/article/c…

When a baby villager spawns, it has 4% chance to have an extra chromosome

Villagers with an extra chromosome, will constantly the devs for the Aether update/ sky dimension. Occasionally they will shout "CAVE UPDATE" from time to time.

These villagers will go up to a player and ask them if they want the Aether in Minecraft. You can then choose to say yes or no. Saying no will make the villager go apeshit. The villager throw a tantrum and will instant kill you with it's screaming. The following death message will say:

"[Player] has failed to submit to the hivemind of the shitty minecraft community"

Saying yes will trigger an orgy of cringy minecraft memes from r/minecraftmemes about the Aether and the Cave update, covering your whole screen.

This would play a big role in the education which Minecraft provides. It would teach the children, that no healthy human, would ever think that the Aether would fit in Minecraft.

Also: these villagers have voted for phantoms

4 STUDIES confirm: The Mediterranean diet protects the heart, the brain, lowers the risk of a diabetes. The diet was also associated with longer telomeres, the protective structures at the end of chromosomes
  • The Mediterranean diet β€” higher in vegetables, fruits, whole grains and olive oil, and lower in dairy products and meat β€” has long been cited for its health-promoting benefits. Researchers have new clues as to why.

  • They found that the diet was associated with longer telomeres, the protective structures at the end of chromosomes. Shorter telomeres are associated with age-related chronic diseases and reduced life expectancy.

  • The study, published in the journal BMJ, controlled for body mass index, smoking, physical activity, reproductive history and other factors, and found that the higher the score for adherence to the diet, the longer the telomeres.

http://well.blogs.nytimes.com/2014/12/02/mediterranean-diet-is-good-for-your-dna/?_r=0

  • According to a study published, in Annals of Internal Medicine, sticking to a Mediterranean-style diet may help reduce the risk for Type 2 diabetes, even when people don’t lose weight or increase exercise levels.

http://well.blogs.nytimes.com/2014/01/13/mediterranean-diet-for-diabetes/

  • According to another study, about 30% of heart attacks, strokes and deaths from heart disease can be prevented in people at high risk if they switch to a Mediterranean diet rich in olive oil, nuts, beans, fish, fruits and vegetables, and even drink wine with meals, a large and rigorous new study has found.

  • β€œReally impressive,” said Rachel Johnson, a professor of nutrition at the University of Vermont and a spokeswoman for the American Heart Association.

http://www.nytimes.com/2013/02/26/health/mediterranean-diet-can-cut-heart-disease-study-finds.html?pagewanted=all

  • A study found that it also protects the brain. This association persisted even after controlling for almost two dozen demographic, environmental and vascular risk factors, and held true for both African-Americans and whites. People with high adherence to the diet were 19 percent less likely to be impaired

  • The study was published in the journal Neurology.

Does anyone actually know what it means to have a missing chromosome at #4? What, if any are the implications?

Medical people of Reddit, I just found out my lad, aged 4yrs, has a chromosomal deletion at #4. Dr said he’s uncertain what it means. Can anyone here help? I’m not sure how to feel...

He’s an amazing boy but has many health and social issues ranging from ASD to skin and breathing issues.

He had a tongue tie at birth that made feeding difficult resulting in failure to thrive. So it was operated on to help his feeding but resulted in trauma based solid food texture issues.

He speaks with a very cute lisp and has been diagnosed with ASD with oral and sensory defensive behaviors.

We adore him but in dealing with his constant skin irritation issues (shocking eczema at times) he had a blood test to see if we could help him sleep better by removing problematic things from his diet.

We’ve tried elimination diets to help his skin and often dysregulated behavior. But his eating issues make it very difficult.

So anyway, long story short. He got a blood test recently and it showed he has a chromosome missing at #4 but no one seems to be able to give us a straight answer as to what that means...

Can anyone here help an anxious set of parents out with any information on what this mean, if anything?

Thanks...

Microarray VUS finding... Chromosome 4

Hello,

Hope this post is okay. 20weeks with a little girl and had an atypical X finding on my Natera NIPT. Decided to go for the amnio, FISH was normal, but microarray identified two duplications on Chromosome 4 which were classified as variants of uncertain significance but are associated with severe cognitive deficits, mitochondrial depletion syndrome, and heart defects. My genetic counselor has not offered much counseling or information except a data dump.

Anyone out there have a similar finding and have it be reclassified or asymptomatic? We are awaiting full karyotype as it is often associated with balanced translocations as well as parental karyotypes at genetic counselor's recommendation.

Thank you.

What is a reproductive bottleneck (based on Y chromosome sequencing) ? How is it possible that between 8,000 and 4,000 years ago, the effective breeding population of women was 17 times that of men.

I read this in a serious anthropology article, but am not myself an anthropologist. By breeding population, I assume one means between the age of 12 and 50? I assume that Y chromosome sampling is a way to determine if a bone fragment (or other type of fragment) comes from a male. thanks very much in advance for your time and help.
