Alzheimer's and the Microbiome
In a groundbreaking study, researchers have discovered that alterations in the human gut microbiome can precede the cognitive declines associated with Alzheimer's disease. The study, led by experts in the gut microbiome and Alzheimer's research, found distinct differences in the gut bacteria of individuals in the preclinical stages of Alzheimer's, even before any visible symptoms emerge. The findings raise the possibility of using stool sample analysis to detect early risk for Alzheimer's, enabling earlier interventions to slow or halt its progression. Further research aims to determine if targeted dietary changes or probiotic treatments can effectively modify the gut microbiome and delay Alzheimer's development.

Mindfulishness: Are Meditation Apps a Distraction Trap?
In the thought-provoking article, Your Phone Is the Wrong Place to Go for Mindfulness, the author explores the paradoxical nature of meditation apps and their relationship with smartphones. While mindfulness apps offer convenient access to meditation practices and promise to bring peace of mind, they also contribute to the ever-present distraction of smartphones. The article questions the effectiveness of using these apps on a device that is notorious for causing unfocus and stress. It highlights the need for mindful choices in our phone usage and suggests that true mindfulness may lie in disconnecting from the screen altogether.
When is Anxiety a Problem?
Anxiety disorders affect approximately 1 in 5 American adults. Understanding when anxiety becomes problematic is crucial. While anxiety can serve as a protective alarm system, persistent worry and interference with daily life may signal the need for evaluation and treatment. Dr. Petros Levounis, President of the American Psychiatric Association, sheds light on recognizing anxiety's red flags and the available treatments. Notably, the article also addresses the omission of older adults from the screening recommendations and emphasizes the importance of discussing emotional concerns with healthcare providers.

Unraveling Statins
Researchers have uncovered the long-standing puzzle surrounding the muscle-related side effects of statins, America's most popular drug for managing cholesterol. While investigating the genetic causes of limb-girdle muscle dystrophy, two independent groups of scientists unexpectedly identified mutations in the gene encoding the HMG-CoA reductase enzyme—the same enzyme statins inhibit to reduce cholesterol production. The discovery sheds light on the connection between a rare genetic disease and statins' common muscle-related side effects, offering potential insights for targeted treatments and improving the lives of severely affected patients.

Forest Bathing in VR
Scientists are studying whether computer-generated forests have the same effect on health and well-being that natural forests do. "Forest bathing" might work in virtual reality too | MIT Technology Review
Dark Side of the Rainbow
In Pink Floyd, 'The Wizard of Oz' and Me, (gift article) a journalist shares his connection to the phenomenon that occurs when Pink Floyd's album "The Dark Side of the Moon" is played in sync with the movie "The Wizard of Oz." The article delves into the strange and surreal coincidences that arise from this synchronization and explores the journalist's role in popularizing the concept through his early internet presence. The story reflects on the cultural impact of this unique pairing and the enduring intrigue it continues to evoke.

Canine Clinical Trials
Dog cancer research is helping drug development for humans and canines (gift article) is about driving advancements in the development of cancer drugs for both humans and canines. Comparative oncology, the study of cancers in companion animals, offers insights into human treatments and has gained momentum due to the high failure rate of cancer clinical trials using mouse models. Studying dogs provides advantages such as shared environmental factors, cleaner data, and easier data sharing, leading to potential breakthroughs in cancer treatment for both species.
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
The neuroscience of trauma is an interesting video featuring Dr. Lisa Feldman Barrett, who contends that trauma alters 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
Aspartame to be Declared Carcinogenic by WHO
The World Health Organization will reportedly categorize Aspartame/Nutrasweet as potentially carcinogenic. Aspartame: Key ingredient in Diet Coke set to be declared 'possible cancer risk' by WHO I also learned of a study last year (in mice) where aspartame increased anxiety and fear processing across generations.Transgenerational transmission of aspartame-induced anxiety and changes in glutamate-GABA signaling and gene expression in the amygdala
