Latest research links higher cardiorespiratory fitness with longer life, even among non-elite athletes.
Research shows small increases in VO2 max and daily activity can extend longevity over time.
Strength training remains crucial in aging, helping maintain function and reduce frailty.
Experts advise a balanced approach: combine cardio and strength rather than chasing extreme regimens.
Moderate daily activity provides meaningful health benefits, with diminishing returns for saturated extremes.
The piece distinguishes between ‘fitness’ (capacity) and ‘exercise’ (activity) to explain outcomes.
VO2 max and METs are used to measure cardiorespiratory fitness and effort.
Muscular strength supports daily activities and long-term independence in older adults.
Experts note that elite power athletes may not gain the same longevity benefits as endurance athletes.
Guidelines suggest 150 minutes of moderate aerobic activity weekly, with personal adjustments over time.

Nguyen argues that mechanical values simplify coordination but blunt human nuance in modern life.
The article defines three kinds of rules: principles, models, and algorithmic rules.
Algorithms historically emerged to cheapen labor by standardizing tasks for broad use.
Nguyen uses cooking as a concrete case where mechanical recipes can replace judgment.
The trade-off: mechanical rules ensure consistency but may sacrifice subtlety and expertise.
Measuring success by counts like Likes and follows reveals a preference for countable outcomes.
The article argues that algorithmic rules can be audited and replaced more easily in organizations.
Nguyen warns that overreliance on mechanical rules can erode craftsmanship and adaptability.
The piece highlights a pizza chef who avoids temperature gauges to cook by feel.
The article ties Nguyen’s ideas to broader debates about value, rules, and modern life.

Latest data shows a moderately severe flu season with ongoing hospitalizations and significant youth impact in major cities like New York.
A subclade K of H3N2 is driving mutations that may reduce current flu vaccine effectiveness.
Vaccination remains a key defense, with early UK data showing substantial protection against severe illness for children and adults.
Researchers are pursuing universal flu strategies to broaden protection beyond annual vaccine updates.
Stem-focused vaccines and nanoparticle displays are in early human trials to broaden immune coverage.
Broader immune targets, including neuraminidase and T-cell responses, could lessen illness severity.
The U.S. is seeing renewed political interest and funding for universal flu prevention research.
Beyond vaccines, antivirals and at-home tests can reduce illness severity and spread.
Influenza remains a global health threat, necessitating ongoing prevention and treatment innovations.
Researchers anticipate vaccines that target conserved viral features to curb drift and improve protection.

Latest review notes that some brain microplastics studies face methodological challenges and possible contamination.
Experts say detecting microplastics in human tissues is very hard and may reflect errors rather than true presence.
Official reviews have raised concerns about missing contamination controls and weak validation in several studies.
Despite doubts, experts agree plastic pollution in the environment is real and exposure through air, food, and water is undeniable.
Researchers call for better methods, clearer standards, and collaboration between medical researchers and analytical chemists.
Experts advise modest precautions to reduce exposure while the science catches up.
Analytical challenges include distinguishing true signals from background contamination in Py-GC-MS methods.
A 2022 study first reporting microplastics in human blood remains under scrutiny amid concerns over measurement accuracy.
Researchers emphasize that even with uncertainty, plastic pollution is a serious environmental issue requiring policy action.
