    Can we finally get rid of superbugs? Or will the bugs just develop a resistance to the quantum dots? Will we elimite any more diseases like smallpox?

    Tiny Quantum Dots May Spell Doom For Deadly Superbug Infections
    Scientists say the light-activated nanoparticles wipe out infectious bacteria without harming healthy cells

    Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans.
    Does nanotechnology hold the key to stopping antibiotic-resistant bacteria and the deadly infections they cause?

    Scientists in Colorado think it just might. They've developed light-activated nanoparticles -- each roughly 20,000 times smaller than the thickness of a single human hair -- and shown in lab tests that these "quantum dots" are more than 90 percent effective at wiping out antibiotic-resistant germs like Salmonella, E. coli and Staphylococcus.

    "In our study, we tailored these quantum dots so they can selectively kill these 'superbugs' without affecting other host mammalian cells (or human cells)," Dr. Prashant Nagpal, assistant professor of chemical and biological engineering at the University of Colorado at Boulder and a leader of the research, told The Huffington Post in an email. "This means, after more careful clinical trials, we can simply administer these dots to patients with infections and it can cure the infection without potential effects (or side effects) for healthy host cells."

    If Nagpal is right, that would be a very big deal.

    Some infections will mutate faster than you can program these nano-dots, and some of these infections make room for a whole host of other bacteria to join in. It may help in some cases, but MRSA is a nasty, nasty situation in some cases like post-surgery.

    I just hope they are right. It would not be pleasant to live in the post antibiotic era.

    These "news" are from January. No new findings in four months. OK, we'll wait for confirmation a bit more.

    I blame OBAMA and the Vast Left Wing Conspiracy for doing this to the U.S., in order to kill off "Da Wite Mens". ;-)

    Report: Antibiotic-resistant Bacteria Threaten Global Physical & Financial Health
    20 Sept.`16 - The growing number of "superbug" infections could push 28 million people into extreme poverty, hurt the economy as badly at the 2008 financial crisis, make health care costs soar, damage livestock production and cost millions of human lives by 2050 unless there is prompt, effective and sustained action.

    I sure hope medical science has some options on the horizon now that we've abused antibiotics to the point of them becoming ineffective.

    We used to quarantine people carrying noncurable infections. It could still save a lot of lives.

    British Scientists: Drug-resistant Malaria Cases ‘A Warning For Africa’
    February 01, 2017 — Four British citizens who caught malaria while travelling in Africa have shown apparent resistance to the main drug used to treat the disease, according to researchers at the London School of Hygiene and Tropical Medicine. Scientists say the discovery should act as a warning for Africa, where the drug has played a key role in sharply reducing mortality rates from malaria.
