The basic program is built around four lifts: the bench press, squat, deadlift and overhead press — supplemented with cardio. And while the program provides extensive adjustments for older bodies, it focuses on relatively high weight, low repetitions and progressive overload, or structuring a training plan to consistently add difficulty.

The New York Times · Pumping Iron Is Their Secret to Aging WellBy Chris Cohen

But worldwide, roughly 10 to 25 percent of lung cancers now occur in people who have never smoked. Among certain groups of Asian and Asian American women, that share is estimated to be 50 percent or more. These cancers are increasingly drawing the attention of researchers... role that environmental exposures, genetic mutations or other risk factors might play.

Annie Chen was diagnosed with lung cancer after two years of reporting persistent shortness of breath. Up to 25 percent of people with lung cancer never smoked.

Studying the relationship between the size and the #anatomy and #physiology of #living organisms has proven useful in order to decipher what the key #physical constraints are that apply to them.

Here we consider both variations of #cellSize, using a drug that blocks mitosis without inhibiting growth, and of the interactions with the substrate, by considering the different stages of the quasi-static process of #cellSpreading, but also by using confinement, and thus presenting more than one substrate for the #cell to spread on. The fibroblasts used in this study present the archetypal shape of a cell spreading on a substrate, with a central cell body which, while flattening, retains a spherical cap shape, and is surrounded by a flat #lamella. We show that this shape is preserved isometrically between the cell size and cell confinement conditions. Moreover, the length ratio that characterises it establishes early during spreading, at the time when #focalAdhesion with the substrate develop. These #adhesion patches also collectively follow an isometric scaling with respect to cell spread area, in spite of having individually a shape, size and density which is insensitive to the global cell shape. We show that this isometry follows from the restriction of the distribution of focal adhesions to the flat lamella.

Since adhesion distribution is crucially important for maintaining the cell shape, we suggest that the observed allometry may be important for the cell to face the #mechanical challenges of physiological function.

But experts say you probably don’t need to reach for a sports drink during your regular workouts. Even if those workouts are strenuous or happen in hotter weather, drinking water when you’re thirsty is enough to keep you hydrated. The sugar and carbohydrates found in many sports drinks certainly may help competitive athletes maintain their energy, but the electrolytes have little impact.

The New York Times · Do You Need to Drink Electrolytes?By Emma Yasinski

Ever wanted to see new colors you’ve never experienced before? Yes, it is possible. Mammals perceive colors based on evolutionary factors that in some cases restrict the number of colors we can see. But there *is* a workaround. Try it out for yourself. #perception #color #Colors #physiology #science dynomight.net/colors/ New colors without shooting lasers into your eyes…

Allen's rule (Ecogeographic rules 🌍)

Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates. More specifically, it states that the body surface-area-to-volume ratio for homeothermic animals varies with the average temperature of the habi...

Today I met someone who can swim down +60 metres and then back to the surface again successfully. On one breath.

(Thats 200 feet down and 200 feet back up. More feet than four centipedes.)

There are probably #Physiology PhDs to be had that would require extensive research on yachts in the Mediterranean Ocean or in Bali.
