    MICROORGANISMS CAN’T HIDE FROM DROPOSCOPE

    The DropoScope is a water-drop projector that works by projecting a laser through a drop of water, ideally dirtywater crawling with microorganisms. With the right adjustments, a bright spot of light is projected onto a nearby wall, revealing a magnified image of the tiny animals within. Single celled organisms show up only as dark spots, but larger creatures like mosquito larvae exhibit definite structure and detail... more

    PRESCRIPTION VIDEO GAMES MAY BE THE FUTURE OF MEDICINE

    “Brain-training” games have been a controversial topic in recent years, especially after a group of scientists and researchers published an open letter in 2014 saying there is “very little evidence” that training your brain in one area or on one task offers improvement in other areas of cognitive function. Shortly afterward, another group of scientists wrote a rebuttal to that, claiming that a “substantial and growing body of evidence shows that certain cognitive-training regimens can significantly improve cognitive function, including in ways that generalize to everyday life.”... more

    Cancer and big-pharma equals big money. They're going to fight against anything that takes money out of their pockets.

    USB 3.2 will make your cables twice as fast… once you’ve bought new devices

    If you've invested heavily in USB Type-C cables, the USB Promoter Group has some good news for you. The next version of USB, USB 3.2, will double the speed of existing Type-C cables. Cables currently qualified for USB 3.1 generation 1's 5Gbps will be able to operate at 10Gbps; those qualified for generation 2's 10Gbps will be able to run at 20Gbps.

    The only small inconvenience is that to use these new speeds, you'll need brand new devices at each end of the cable. But if you've managed to find some Type-C cables that actually properly comply with the specification—something that's harder than it should be—you can rest assured that they'll continue to work with the new spec, without holding back the performance of your devices.

    As for how the cables are able to double in performance, the explanation is simple enough. One of the most compelling features of USB Type-C is that it can be used for more than just USB signalling; other protocols such as Thunderbolt 3 and DisplayPort can use the same ports and the same cabling. To support this flexibility, the ports and cables have four pairs of wires used for high-speed data transmission. While some protocols, such as Thunderbolt 3, use all four of these pairs simultaneously, USB 3.1 only uses two of them—one pair for transmitting data, the other pair for receiving it—with the other two going unused.

    USB 3.2 will enable USB devices to use all four pairs simultaneously, providing a simple way to double performance of existing cables.

    The full USB 3.2 specification is expected to be finalized in September. Apart from doubling the speed by doubling the number of pairs being used, it is a minor update. The way that data is encoded and transmitted will be unaltered. The hub specification is being changed to ensure that it can properly handle switching between two-pair and four-pair operation, but that's the full extent of the changes.

    Yes, but it's not only money. It's about to have control about the therapy itself and the resulting dependency. Inaction and senseless claims make it hard to get better therapies.
    It protects the sovereignty of the establishment and delays real research.
    I had a closer look on Doctor Friesen's works, also on interviews with people who have experiences with Methadone supported Chemo. And I know somebody personally who tries to get such a treatment....(suffere(s)d from brain tumor)..

    Doctor Friesen's works are important, impressing, significant and IMO a real option for people who suffer from cancer.

    And I know an interview with a medic who does not acknowledge the successes and his flimsy arguments. :mad:

    There are a lot of dirtbags amongst the scientists, sorry for my wording.

    I hear Big Pharma found the cure for cancer decades ago....but curing cancer is not profitable:rolleyes: Big Pharma is not in the business of finding cures their in the business of having costumers.

    @MS_User: There are literally hundreds of types of cancers, each with it's own treatment and prognosis.

    yes their many types of cancer but if the pharmaceuticals found the gene that causes cancer and they can turn it off....now lets say like skin cancer a lot of people bring that on then self...like at the beach people frying their bodies out their to the max or people eating constant garbage like process foods full chemicals....yes does things can also give u cancer or drinking contaminated water were so many people are facing that problem in the world now. But dont let yourself be full Big Pharma is not in the business of cures.

    MJ is right.
    There are 'issues' with established science and research and issues with marketing and science. I know some from my profession. Established science is sticking to their sovereignty and marketing has money related interests. This leads to conflicts on the costs of the people who are suffering from such diseases.
    Also different prices for the same medicament in different countries is a big issue. Some dealers just make re-imports from cheap countries to more expensive ones. The effect is that people from the cheap countries don't have enough of such medicaments themselves! And the dealers shamelessly take profit from the difference in price.


    But there is no simple 'switch' where you can turn off cancer. There are genes which are cancer/disease related. They can give info about a probability to suffer in life from such.
    We should focus on 'issues' case related, general statements like: There is in fact a remedy for cancer, but big pharma is holding it back are not true.

    There are substances which firstly have got a bad reputation and hence a hard way to get new objective interest for cancer treatment, though.
    But they do only have success at particular kinds of cancer.

    One of it is thalidomide. It has got its bad reputation by the 'Contergan scandal'. It has been released as tranquillizer also approved for pregnant women. What people did not know is that it suppresses a growth-factor which is important at a few embryonic development states. It leads to deformity at the extremities or organs.
    A similar growth factor plays also a role at the growth of some cancer types. Thalidomide can be used to treat such cancer by suppressing the growth.

    Thalidomide is also used to treat leprosy.

    The second one now is Methadone. It is known as Heroine substitute and is strongly physically addictive, though.
    Cancer cells seem to have many more opioid receptors than normal cells. Methadone can tie to such and change the permeability of the cancer cells for Chemotherapeutics.
    This means the selectivity of Chemotherapeutics can be increased by an additional administration of Methadone. The chance that they get into the cancer cells is far higher and their duration inside is also longer. Means the probability that the tumour shrinks and leaves back an inactive something or vanishes completely can be far higher.
    Sick people who have got a bad prognosis for their rest of lifetime could be cured. I have seen and read many cases.
    The side effects of Methadone can be well controlled. They are obstipation and stomach problems.

    The life time addiction to it is no problem in relation to lethal cancer...and if indicated Methadone withdrawal can be successful by working out a doses-plan.
    While Thalidomide has got back its place Methadone is still not approved as supportive for chemo. Not even all medics know about yet! And it is actually unwanted for those who are involved in profits by Chemotherapeutics.
    And established science has its strict regulations. Not approved for it means no prescription for you.

    People who want to use it have to find places where they offer a study/trial....

    After 43 years, gentle touch of a neutrino is finally observed

    Neutrinos are noted for being extremely reluctant to interact with other matter. While it's possible to build hardware that will detect them, these detectors tend to be enormous in order to provide sufficient material for the neutrinos to interact with. Those interactions also take the form of energetic events that transform the identity of particles (for example, converting protons to neutrons).

    Given the neutrino's low mass and tendency not to interact, the idea of detecting one simply bumping into another particle seems almost ludicrous. But that's what scientists from Oak Ridge National Lab are reporting today. They've seen brief flashes as atoms get nudged by a neutrino, which imparts a tiny bit of its tiny momentum to the atom's nucleus.

    Oak Ridge National Lab is home to some hardware called the Spallation Neutron Source. This accelerates a beam of protons and smashes them into a tank of mercury. This creates debris that includes lots of neutrons, which are used for a variety of scientific purposes. But the debris also includes some neutrinos that are otherwise lost in the spray of particles that comes flowing out of the collisions.

    When they got the idea to start using the neutrinos, the researchers at the facility started placing detectors to find any areas of the building that didn't receive as many neutrons. They came up with an area that had a lot of concrete and gravel between it and the mercury tank: "A basement corridor, now dubbed the 'neutrino alley.'" The corridor was fitted with a large water tank to block out more of the neutrons and other particles, as well as cosmic rays from the atmosphere.

    The neutrino interactions we've detected previously all involve neutrinos slamming into the target material and triggering some sort of particle transformation. In this case, we're looking to see the neutrino bump into the nucleus and give it a slight nudge. More technically, we're looking to see the neutrino give some of its momentum to the nucleus by exchanging a Z boson with one of the nucleus' quarks, after which the nucleus loses that energy by emitting a photon. This interaction was first proposed on theoretical grounds 43 years ago but has remained undetected.
    A number of things make this sort of interaction more likely. One is having a relatively low-energy neutrino, something that the Oak Ridge facility provides. A second is having a relatively large nucleus for it to bump into. The research team handled this by making a detector with cesium iodide, two relatively heavy elements. Because these elements are similar in mass, the photons they emit after an interaction should be similar in energy, ensuring that a single detector can pick up any interactions.

    So 14.6kg of cesium iodide was set up in the basement beneath the mercury tank and flanked by photodetectors to pick up the light emitted by the interactions. Then, the team took data for a bit over a year.

    The neutron source provided a great experimental control: protons slammed into the mercury in pulses, which allowed the researchers to take data from times in between the pulses, as well as times just after them. By comparing the two, they could see what was different between them. And what was different was a slight excess of events—about nine a month—right after a pulse of protons hit the mercury tank. This is consistent with predictions from the Standard Model of particles. And it's nearly seven standard deviations away from what you'd expect if you weren't seeing neutrino interactions.

    So, 43 years after this was all predicted, we finally have experimental support that neutrinos can bump into an atom. The authors, however, seem just as excited about the rest of the work they're doing. They've set up several additional detectors to track the neutrinos down in the basement, and they have upgraded their source. In addition, the researchers think it might be possible to use their cesium iodide-detector expertise to make a small, portable neutrino detector. Getting rid of the need for building-sized hardware to detect neutrinos could open up some previously impossible experimental opportunities.

    With genetic morph, a weird type of anthrax has emerged—and it’s on a rampage

    After getting ahold of the genetic blueprints for molecular weapons, relatively harmless bacteria transformed into one that can cause anthrax—in places and animals where the original anthrax bacteria doesn’t. And it’s wreaking havoc.

    Using data collected over a 26-year period, researchers found that this strange version of anthrax is running rampant in tropical rainforest habitats of Sub-Saharan Africa, killing off broad swaths of mammals. In fact, researchers estimated this week in Naturethat this "rainforest anthrax" could wipe out chimpanzee populations in the Côte d’Ivoire’s Taï National Park within the next 150 years. It’s currently associated with nearly 40 percent of all chimp deaths there. And researchers are just getting started on understanding risks to humans, which have so far been thought to be low... more
