The Dark Secret of Leeches | How Do They Drink Blood Without Pain? What if I told you a tiny creature can attach to your skin, make a Y-shaped cut, numb the area, and drink your blood without you even noticing? Leeches use one of nature's most advanced biological systems. Their saliva contains Anesthetic that reduces pain, Hirudin that prevents blood clotting, and Vasodilators that widen blood vessels, allowing blood to flow continuously. This is why a leech can consume several times its own body weight in blood. But here's the surprising part... Modern medicine still uses medical leeches after delicate surgeries to restore healthy blood circulation and improve healing. In this video, you'll discover: How a leech bites without pain The science behind Hirudin Why blood doesn't clot How hospitals use leech therapy today • Watch till the end to uncover one of nature's strangest biological secrets! Follow me deep science, biology, wildlife, and Al-powered educational videos. #Leech #Leeches #Science #Biology #Blood Medical Science Wildlife Nature AnimalFacts ScienceFacts Hirudin MedicalLeech Education ExplainXAI Viral Reels Explore Page Reels Knowledge Documentary Al

Elon Musk predicts that within the next three years, Tesla’s Optimus will become a better surgeon than even the most skilled human surgeons The world is currently facing a growing shortage of surgeons. Human doctors are limited by time, fatigue, and availability When Optimus reaches that level of precision and scalability, it will bring high-quality surgical care to millions who currently have little or no access This is how we move toward abundance in healthcare

A scientific rebuttal to a dangerous pseudoscience. [1/2] The "leech therapy" promoted on social media and in alternative medicine clinics is a dangerous pseudoscience that bears no resemblance to the legitimate, highly specialized medical use of leeches in micro-surgery. One is a last-resort surgical tool, applied under the strictest safety protocols to manage its inherent dangers. The other is an unproven, unregulated ritual based on archaic beliefs, performed without any regard for patient safety. There is absolutely no scientific evidence to support the use of leech therapy for the treatment of cancer. The claims are based on a deliberate misrepresentation of preliminary lab research. Patients who are lured by these false promises risk abandoning effective, life-saving treatments, a decision that can have fatal consequences. The risks of severe, drug-resistant bacterial infections, uncontrolled bleeding, and the transmission of blood-borne diseases like HIV and hepatitis are not theoretical; they are real and life-threatening. Even in modern hospitals that use prophylactic antibiotics, infection rates following leech therapy are reported to be as high as 20%. Aeromonas species in leeches are naturally resistant to many first-line antibiotics making these infections incredibly difficult to treat. In an unregulated setting (like an Ayurveda clinic) where no antibiotics are given, the risk of a severe, potentially untreatable infection is unacceptably high. This is the strongest possible warning to the public: Never seek leech therapy for cancer or any other systemic disease. It is not an effective treatment and will cause you harm by delaying proper medical care. Avoid any practitioner promoting leech therapy for conditions beyond its narrow, FDA-approved surgical use. Such individuals are not offering a valid "alternative" therapy; they are marketing a dangerous and discredited practice. Trust evidence-based medicine. Decisions about your health, especially when facing a serious diagnosis like cancer, should be made in consultation with qualified medical doctors and based on rigorous scientific evidence, not on viral videos or promises of ancient cures. Choosing unregulated leech therapy is not an informed choice; it is a disastrous and potentially deadly mistake.

How many American journalists land in Iran without pre-written headlines? How many speak to a single person not arranged by their fixer? RT's Rick Sanchez is one. More real Tehran in three minutes here than ten years of CNN reporting.

This field hospital for Ukrainian soldiers is located at a depth of 6 meters at the front line. The surgeons working here know how to carry out the most complicated operations, as seriously wounded soldiers are also admitted here. More than a thousand lives have already been saved in six fortified bunkers-wards. 📹: Current Time
