    New Stroke Treatment: Quick Removal of Clot for Good Recovery

    There is a new treatment for strokes described in this NY Times article. It has to happen quickly and requires big (non-portable) equipment. If the stroke is a blockage of blood flow by a clot, rather that a burst vessle, the location of the clot can be identified by CT scan and endoscopically...

    Are Antineoplastons actually a cure or significant treatment of cancer

    The FDA has been constantly trying to take away this doctor's license away for 40 years, and many says the doctor is a quack. But apparently there are many patients that back him and claim that the doctor cured them with antineoplastons. Many patients had brain cancer which is untreatable in...

    Medical Varicose vein treatment with fiber lasers

    So I've read that varicose veins can be treated using fibre lasers. First, anesthetics are used locally to numb the limb and also act as an insulator for heat. Then, a small cut is made and a fiber is guided to the vein. Using laser light somehow the vein shrinks. This is what I don't...

    I Newton vs Einstein: Explaining Other Forces

    Under Newton, gravity is what I term an "invisible magic rope" that pulls you down. Enter Einstein. We do away with the invisible magic rope, and say that space (or space-time) is warped by mass. However, we still have other forces, that (as far as I know, anyway) are "invisible magic ropes."...
