Nutrition Science How Do You Really Digest Protein?  4 min read  May 2026  Verified Protein   Digestion   Gut Health   Muscle & Recovery You eat chicken, eggs, or lentils — and somehow your body turns that into muscle, hormones, and energy. But how, exactly? The journey protein takes through your body is far more fascinating than most people realize. Protein doesn't just get "absorbed." It goes through a remarkable, multi-stage breakdown process before a single amino acid reaches your bloodstream. Here's the real story — from first bite to final cell. You don't just digest protein. You transform it. Credits: AI@ FST The digestion journey 1. It starts in your mouth Chewing physically breaks protein into smaller pieces. Saliva doesn't digest protein directly, but thorough chewing gives your stomach a head start — skip this and everything downstream works harder. 2. The stomach — acid bath Your stomach releases hydrochloric acid (HCl), dropping pH to aroun...

     Sleep Science Why do you still feel sleepy even after  8 hours  of sleep?  4 min read  May 2026  Verified Sleep Quality   Fatigue   Brain Health   Wellness You did everything right — early bedtime, 8 full hours, no alarm disruption. Yet you wake up feeling like you barely slept at all. You're not broken. But something in your sleep is. The number of hours you sleep is only half the story. What matters just as much — arguably more — is the quality of those hours. Here's what science says is really going on. That heavy, can't-lift-my-head feeling after a full night's sleep? It has a reason. And it's not laziness. Credits: AI@ FST The real reasons you wake up exhausted You're skipping deep sleep Your body cycles through light, deep (slow-wave), and REM sleep. If you're not reaching deep sleep — often disrupted by alcohol, stress, or screen light — you miss the stage where physical repair actually happens. Undiagnosed sleep apnea M...

You toss and turn, stare at the ceiling, and check the clock for the hundredth time. Another sleepless night. You’re not alone. Millions struggle with insomnia or poor sleep quality every single night. The real problem? Modern life has quietly sabotaged your sleep without you realizing it. The biggest culprit is blue light from screens . Your phone, laptop, and TV emit blue light that suppresses melatonin, the hormone that signals your body it’s time to sleep. Scrolling social media or watching Netflix until midnight tricks your brain into thinking it’s midday. Even dim bedroom lights can disrupt your circadian rhythm. Credits: AI@ FST Stress and anxiety come in a close second. Your brain doesn’t switch off when your body does. Worries about work, money, relationships, or tomorrow’s to-do list keep your mind racing. Cortisol levels stay elevated, making deep, restorative sleep nearly impossible. Then there’s caffeine and late eating . That afternoon coffee or energy drink can affec...

Protein-Templated DNA Synthesis: Bacteria totally Just Broke a Fundamental Rule of Molecular Biology Reverse syntthesis of DNA strand from protein' amino acid sequences via action of Drt3b Credits: ai@ FST Title: Protein-templated synthesis of dinucleotide repeat DNA by an antiphage reverse transcriptase Authors: Pujuan Deng et al. (Stanford University / Alex Gao lab) Journal: Science (First Release, April 16, 2026) DOI: 10.1126/science.aed1656 The Big Deal For decades, the central dogma of molecular biology has held that nucleic acids (DNA and RNA) are synthesized using other nucleic acids as templates. DNA polymerases copy DNA from DNA; RNA polymerases copy RNA from DNA; reverse transcriptases copy DNA from RNA. Protein → nucleic acid information transfer? Strictly off-limits in the classic formulation. This new paper shows a bacterial defense enzyme that literally uses its own protein structure as a template to synthesize a specific DNA sequence. It's not full rev...

Most people have never heard of heart cancer and for good reason. Cardiac tumors are extraordinarily uncommon compared to cancers in other organs. An illustration  by Ali Hajiluyi on Unsplash Primary cardiac tumors (those that originate in the heart itself) occur in roughly 0.001% to 0.3% of autopsy cases, with an incidence around 1.38 per 100,000 people per year in population studies. About 75-90% of these are benign, most commonly myxomas (especially in adults) or rhabdomyomas (in children). Malignant primary tumors, like sarcomas, are even rarer. Secondary (metastatic) tumors—from lung, breast, or melanoma—are 20-40 times more common than primary ones but still uncommon overall. Why So Rare? The heart’s unique biology explains this rarity. Unlike skin, lung, or colon cells, adult cardiac myocytes (heart muscle cells) are largely terminally differentiated . They exit the cell cycle early in life and rarely divide. Cancer typically requires repeated cell division for muta...
