The concept of “muscle memory” is well established, referring to the phenomenon whereby previously developed muscle can be regained more readily following a period of detraining. It is commonly believed that these effects are attributed to additional nuclei acquired during training, which are permanently retained even if you stop working out.
But is this really how muscle memory works?
A recent review by Serrano et al (PMID: 40768525) challenges this conventional explanation, suggesting that the mechanisms underlying muscle memory may be more complex than previously thought.
Some key takeaways:
--Although short periods of detraining generally result in little change in myonuclear number, evidence from both animal and human studies suggests that myonuclei may be lost with prolonged detraining or muscle atrophy. At a minimum, the evidence remains conflicting, calling into question the notion that myonuclei are permanently retained.
--Methods matter. Accurately counting myonuclei is technically challenging, and differences in measurement techniques may help explain conflicting findings.
--The mechanisms remain unresolved. Retained myonuclei may contribute to muscle memory under certain conditions, but the evidence does not establish that they are the sole—or necessarily primary—mechanism.
--Other factors may contribute. Persistent molecular adaptations, particularly epigenetic changes that regulate gene expression, have been shown to enhance the hypertrophic response when resistance training is resumed (e.g., PMID: 40183698).
Bottom line: Muscle memory is a well-established phenomenon, but the notion that it is driven solely by the permanent retention of myonuclei is increasingly being questioned. While retained myonuclei may contribute to this effect, lasting molecular modifications may also play an important role in facilitating muscle regrowth when training resumes.

🚴 Endurance supplements: Science vs hype! 🔬
☕ Caffeine: effective
🥤 Bicarbonate: boosts intense efforts
🍷 Nitrates: modest benefits
🍌 Carbs: essential for long events
💪 Creatine: limited endurance benefits
Train first. Supplement second.

🏋️ Strength training builds more than muscle!
A meta-analysis in youth found improved self-efficacy (g=0.54) and self-esteem (g=0.41).
Promising, but evidence is limited.

Still can’t believe this happened.
The sugar industry funded Harvard researchers to downplay evidence linking sugar to heart disease and point the finger at fat instead.
And the funding wasn’t disclosed.

Intelligence must draw on memory. The mind must not simply compile data — as an algorithm now does more quickly than we can — but recall lived experiences, which contain depths of meaning that only the human soul can recognize, and connect more deeply with the goodness of these experiences. Everything that is good begins “with the Spirit” and thus possesses a breath, a dynamism and a sense of communion that, once experienced, are engraved upon the heart. vatican.va/content/leo-xiv/e…

One of the lesser-known miracles surrounding the Tilma of Guadalupe is that its stars form more than decoration. They are music!
They have been linked to the constellations visible over Mexico in December 1531, arranged as if seen from beyond Earth.
When the stars and flowers on the tilma are placed on a musical staff, they produce a harmonious melody.
To Catholics, it sounds like a song written into the image itself.
Listen:
The tilma of Guadalupe still hasn’t decayed after 500 years. But that's not even the craziest thing about it.
Only modern tools discovered this.
A reflection of witnesses, 1/100th of a millimeter.
The cactus fiber should have disintegrated in 20 years; it is perfect after 500.
But the craziest part is the eyes. When magnified 2,500 times, the eyes of the Virgin Mary image contain the perfect reflection of the people who were present when the miracle happened (Juan Diego and the Bishop).
The reflection follows the laws of Purkinje-Sanson optical curvature. No human painter in 1531 knew that, let alone could paint it on a microscopic scale.
Impossible to have been forged in the 16th century.

The pope really just said
In this era of artificial intelligence, it is becoming urgent to distinguish human art from what machines produce. There is an ontological difference, even before an aesthetic one, between art and what a machine can generate through statistical calculation based on millions of images created by others. Algorithms lack the spark of humanity. For this reason, the Church wishes to renew an alliance with artists and cultural institutions to safeguard our humanity.

The St. Bernard dogs are Catholic.
For centuries, Augustinian canons at the Great St. Bernard Hospice sheltered travelers crossing the dangerous Alpine pass between Switzerland and Italy.
Their powerful dogs became famous for locating people lost in snow and avalanches, eventually giving rise to the St. Bernard breed.
The iconic brandy barrel is mostly legend, but the rescue tradition is real: these monastery dogs are credited with helping save thousands of travelers.
One of history’s most famous rescue dogs began at a Catholic monastery in the Alps.

Nutrition can support injury prevention and recovery when the basics are covered first 🩹
This new review examined nutrition strategies to reduce sports-injury risk and support recovery, covering hydration, macronutrients, micronutrients and supplements 🔍
Here are the key findings ⬇️
💧 Maintaining euhydration is a priority, with fluid and electrolyte plans individualised to sweat losses
⚠️ Dehydration can impair cognition, balance and thermoregulation, potentially increasing injury risk
🥤 After substantial fluid loss, ~1.25–1.5 L fluid per kg body mass lost is recommended alongside electrolytes
🍞 Carb availability supports training quality and glycogen restoration, with ~30–60 g/h recommended during prolonged exercise and up to ~90 g/h in some scenarios
🥩 Protein intake of ~1.4–2.0 g/kg/day is recommended to support tissue repair, with total daily intake more important than a narrow post-exercise “anabolic window”
🥑 Fat should provide at least ~20% of energy, with omega-3-rich foods potentially supporting inflammation control and recovery
🦴 Calcium and vitamin D are important for bone health, while vitamin D deficiency may impair muscle repair and increase bone-injury risk
🩸 Iron inadequacy can compromise endurance performance and recovery
🐟 Omega-3 supplementation may support muscle preservation during immobilisation and concussion recovery, although evidence remains inconsistent
💪 Creatine may help preserve muscle mass and strength during immobilisation and rehabilitation; 2–5 g/day can be effective without loading
🧬 Collagen or gelatin plus vitamin C around loading exercise may support collagen synthesis and connective tissue rehabilitation
🛡️ Athletes using supplements should favour third-party tested products
Adequate energy, carbohydrate, protein and personalised hydration should form the foundation of injury recovery, with supplements added selectively where there is a clear evidence-based role ✅
