LONG NOTES:

A precious story shared by a former student:

I’m visiting my family right now in Massachusetts, and last night we had a big family dinner that also included my cousin. We were playing a game I made up where I pose an open-ended question and then we go around the table to give our answers and someone awards a point to the best answer. Just family fun.

I asked the question: “who is the most under-rated person in history?” and there were lots of good answers! The person who invented scissors, the person who made the first printing press in China, etc. and then it was my cousin’s turn. She lit up and said “whoever figured out the nutritional values for foods and vitamins. Like, whoever figured out how much vitamin C or vitamin A or whatever we need every day. That person did so, so much for humanity in ensuring people could stay healthy through their diet and it also made a huge change in how we help feed the starving and create emergency food for disasters. Lots of people would be really sick or dead without this nutritional guidance”.

When she was done speaking I had the absolute pleasure of telling everyone that not only was that a great answer, but that I *know* this person. I got to tell my family all about you and your work and your studies and how awesome you are. It was the highlight of the whole meal.

 

An international team of researchers reports that the immune cells of older adults with a history of endurance training are more effective at combating inflammation.  Regular physical activity not only benefits the muscles, lungs, and heart, but also enhances the body’s immune defenses. This conclusion comes from a study involving older adults with long-term experience in endurance exercise, which includes activities such as long-distance running, cycling, swimming, rowing, and walking.  In addition to analyzing the phenotype, function, and mitochondrial metabolism of NK cells in response to inflammatory stimuli, the researchers exposed expanded NK cells from trained and untrained older adults to different pharmacological blockers, such as propranolol and rapamycin.

 

 

 

Psychological Resilience and Sleep Quality Among the Elderly: The Mediating Role of Social Support.  In the elderly population, psychological resilience and sleep quality are significantly associated, with social support acting as a mediator in this relationship.

 

The integration of artificial intelligence (AI) tools in scientific writing has accelerated dramatically; yet a concerning transparency gap persists.¹ While current data indicate that researchers are increasingly adopting AI assistance for manuscript preparation, disclosure rates remain surprisingly low, despite evolving publisher requirements.² This phenomenon reflects deeper tensions between technological advancement and traditional academic evaluation systems, creating what may be termed a “transparency paradox” in scholarly publishing, where the tools most capable of enhancing research productivity also pose the greatest risks to scientific accountability when used without disclosure.

Beyond the Pillow: Linking Subjective and Objective Sleep Measures to Gut Microbiome Composition in Community-Dwelling Older Adults.  These findings suggest that specific gut microbial taxa are associated with subjective sleep disturbances in older adults.

The Mechanisms of Magnesium in Sleep Disorders. Magnesium not only reduces the excitability of the nervous system and alters muscle relaxation but also regulates cellular biological clocks, energy balance, and circadian rhythms, playing a crucial role in sleep regulation. Magnesium deficiency not only shortens the effective sleep duration but also impairs sleep quality, leading to various specific sleep disorders.

Excessive Screen Time (ST) Associated with Emotional and Behavioral Problems (EBP) Mediated by Sleep Disturbance Among Young Children. Excessive ST was significantly associated with EBPs and may be mediated by sleep disturbance. Reducing children’s ST and encouraging good sleep practices may enhance mental health.

 

The findings indicate that while there is no significant association between obstructive sleep apnea and prostate cancer.

 

A bio-adhesive for closing wounds. Scientists at Israel’s Technion Institute have developed biomimetic hydrogel bio-adhesives that can seal wounds quickly and effectively even under extreme conditions and environments. The scientists were inspired by how mollusks / molluscs adhere to wet surfaces.

 

Unlocking the secrets of aging. Researchers at Israel’s Ben-Gurion University and at Israel’s Weizmann Institute have discovered a new subset of T helper cells – CD4-Eomes cells – are prominent in people well over 100 years old. these T helper cells act to clean out the system of senescence cells that accelerate aging.
