The anatomy of 'Mashle,' as described by a doctor

Read a deep dive on the 'all-purpose healing' peptide BPC-157

The unapproved peptide—which has received glowing testimonials from bodybuilders, biohackers, popular podcasters, and some in the MAHA movement— is often sourced from China. It has been used for myriad conditions. But scientific questions about the substance abound, including whether it's truly a natural substance produced by the human body, since genetic material that codes for its unique amino acid sequence hasn't been found in the human genome or the gut microbiome. Other unknowns include how it works in the body, which receptors it targets, and its safety, since evidence beyond anecdotes remains scant in humans.

‘Moshing,’ an aggressive style of dancing, was initially called 'mashing'

The style, which involves audience members thrashing their bodies into one another, evolved from “pogoing,” a style popular in England where listeners jumped up and down in place.

Hysterical strength allows someone to lift a car off their child

When the body responds to an acute crisis—say a family member trapped under a car—people can sometimes perform seemingly superhuman feats. This is more than an urban legend: In 2012, a 22 year-old-woman lifted a vehicle off her father, and seven years earlier another man lifted a vehicle off a trapped cyclist. Yet scientists are still unraveling details about why this can occur.

Muscular system explained

Skeletal, cardiac, and smooth muscles form the system that powers movement, survival, and daily life. Skeletal muscles are voluntary, enabling conscious actions like lifting or walking, while cardiac and smooth muscles are involuntary, controlled by the autonomic nervous system. From every heartbeat to each breath, these three muscle types work in harmony to keep you moving, thriving, and alive.

Understand the differences between manga and comics

Manga and comics—often conflated with one another—are two distinct art forms. Manga is predominantly black-and-white, with long and continuous story arcs by a consistent creator. Western comics, meanwhile, are done in full color, released as individual issues, often feature multiple creative teams, and encourage shorter and self-contained narratives.

Using fitness wearables to track muscle wasting in astronauts

All that exercising, and astronauts still are likely to lose a large amount of muscle mass while in microgravity. Astronauts can lose up to 20 percent of their muscle in as little as five days in space. Currently, tracking muscle loss means waiting until astronauts land to remeasure their muscle density post-trip. This article explains a NASA-backed fitness wearable that may be able to track muscle atrophy as it happens.
