The Brain as a Prediction Engine

"For as long as we've studied human cognition, we've believed that our senses give us direct access to the world. We see what's there—or so the thinking goes. But discoveries in neuroscience and psychology have turned this assumption on its head. What if rather than perceiving reality passively, your mind actively predicts it?" I just bought the book The Experience Machine: How Our Minds Predict and Shape Reality.

Trauma Hijacks the Prediction Algorithms of the Brain

Anti-Prosopagnosiacs: Human Super-Recognizers Outshine AI in Facial Recognition

Current facial recognition technology has error rates ranging from 48 to 62 percent. To address this issue, police forces in London, Berlin, and Queensland have enlisted super-recognizers help—individuals with an innate talent for recognizing unfamiliar faces. Studies show that these human experts excel in challenging scenarios where AI falls short, such as low-resolution images or crowded environments. However, racial bias remains a challenge even for super-recognizers. Researchers aim to identify exceptional talents and uncover the secrets behind their extraordinary face recognition abilities. Police Are Using Human Super-Recognizers to Replace Facial Recognition Algorithms in Some Contexts.

End the Tyranny of Processed Food

"Anyone who's struggling with [food-related disease] as an individual should take their guilt and shame and transfer it outwardly to the corporations that are feeding us these addictive substances, to the governments doing nothing about it, and to the physicians and the social media personalities who keep telling us that this stuff is healthy. We must end the conflict of interest between the industry, politicians, doctors, and scientists. Only then can we tackle the problem." An opinion piece about the role of processed food in today's society. I agree with most, except for the part about physicians conspiring. The actual problem with physicians is a lack of understanding. It's Time to End the Tyranny of Ultra-Processed Food

Long Telomeres

"Short telomeres were thought to be bad — people with premature aging syndromes had short telomeres — so, by analogy, long telomeres were thought to be good..." A paper published last week, Familial Clonal Hematopoiesis in a Long Telomere Syndrome | NEJM, challenged current assumptions about telomere length. Link Between Long Telomeres and Long Life Is a Tall Tale, Study Finds - The New York Times

Rapamycin

"Rapamycin is a paradoxical drug. It improves anti-cancer immunity, but it may also cause cancer. It protects against bacterial infection, halts viral replication, and suppresses the immune system. It reverses symptoms of Alzheimer's disease but also increases plaque deposits in the brain. It improves metabolic function, but it also causes type 2 diabetes. This list of contradictions goes on and on; however, there is one thing about Rapamycin that scientists tend to agree on: it is potentially the most powerful anti-aging drug ever discovered." I learned quite a bit from the article: Rapamycin: Unlucky history of the most powerful anti-aging drug.
