@PeterSchiff@JoeSquawk I think the issue with BTC is not that it’s not a precious metal. It was marketed as a decentralized means of exchange but it really is super centralized and easily monopolized because it’s finite. BTC is the trap to get everyone suckered into the new system.
Fertilization is not random, and the fastest sperm does not always win: in reality, the egg decides who succeeds.
While for decades we were taught that fertilization is a race won by the fastest sperm, a study published in Proceedings of the Royal Society B shows how human reproduction actually works.
Scientists analyzed follicular fluid from 60 couples undergoing fertility treatment at St Mary's Hospital in Manchester, UK. They discovered that the egg releases chemical signals (chemoattractants) that actively attract sperm from certain men over others.
Through these chemical signals, the egg exerts its own biological selection, influencing which sperm manage to get close. The egg appears to favor sperm that offer optimal genetic compatibility with its own genome — particularly in genes related to the immune system — which may help produce healthier offspring.
Interestingly, this cellular preference does not always align with the couple’s conscious partner choice. In many cases, eggs showed stronger attraction to sperm from non-partner males.
This chemical communication demonstrates that female biology continues to evaluate and select options even after intercourse. Understanding this process could lead to more precise solutions for unexplained infertility. Science continues to reveal the remarkable level of biological interaction that occurs during reproduction.

@OutsiderEdgeX Hi do you have tutorials? Also you said you were top 3 at FTMO. I've started with FN. I was profitable for a week then I started losing every trade back to back. I want to go back in but I've lost confidence a little. Do you have any proof as to your placement at FTMO?
David Sinclair's lab is using AI to build a pill that reverses aging for $100.
Right now, their gene therapy costs roughly $10 million to manufacture. It requires a direct injection into the target organ.
That's not going to work for 8 billion people.
So Sinclair's team made a breakthrough. They found that the three age-reversal genes aren't the only path to resetting cells.
They discovered CHEMICALS that do the same thing.
In mice, they can now give an animal a liquid — not genes, not injections, a drink — and rejuvenate tissues in 4 weeks.
Sinclair says it's now normal for his students to casually report: "We just rejuvenated the ear. We just rejuvenated the skin. We just cured ALS (motorneuron disease) in these animals."
He calls his lab "Willy Wonka's chocolate factory" because the discoveries blow him away every week.
But he wants one molecule that does everything. So they used AI to screen 8 BILLION candidates. They're now down to three molecules that work. And they're using AI to try to combine all three into one.
The gene therapy could cost over $100,000 per treatment. Sinclair's goal: "What if it could be $100 instead? That's what I'm working for. I want to democratize this technology so anyone even in Kenya can take these medicines."
They should know within a year or two if the molecules work in mice.
The gene therapy is the proof of concept.
The pill is the endgame.

Scientists just made 50-year-old skin cells behave like they’re 20 again.
Researchers at the Babraham Institute in Cambridge have developed a groundbreaking method to reverse the biological aging of human skin cells by approximately 30 years, all while keeping them as fully functional adult skin cells.
The team used a carefully controlled, short-term version of the Nobel Prize-winning Yamanaka reprogramming technique. By exposing adult skin fibroblasts to a specific set of reprogramming factors (the Yamanaka factors) for just 13 days—and then stopping the process early—they successfully “reset” many molecular markers of aging without pushing the cells all the way back to a stem cell state.
After this brief treatment, the rejuvenated cells displayed a dramatically younger profile: their epigenetic clock (a measure of chemical tags on DNA that tracks biological age) and their gene expression patterns (the transcriptome) closely resembled those of cells from much younger individuals.
Even more impressively, the cells behaved younger too. The treated fibroblasts produced significantly higher levels of collagen—the protein essential for skin firmness, elasticity, and wound healing—and they migrated faster to close an artificial “wound” in laboratory dishes compared to untreated older cells.
The researchers also observed reversal of age-related changes in genes associated with diseases such as Alzheimer’s and cataracts, suggesting the technique could have broader therapeutic implications.
While this work is still in its early stages and the precise mechanisms remain under investigation, the findings open exciting possibilities: one day, scientists may be able to selectively rejuvenate aging cells in the body to enhance tissue repair, improve healing, and potentially slow or mitigate some effects of age-related diseases—without the risks associated with fully reprogramming cells into stem cells.
