    This is my argument for government science budgets.

    Headline: Scientists Spend Millions Studying Andean Frog Fucking Habits!

    “What a waste!”

    What if I told you those scientists were making more frogs to study how they can freeze solid and thaw out? Or how limb regeneration works?

      Practically all meds come from science like that.

      why are you studying Easter island soil? discovery of Rapamicin and the cell cenesense pathways in human cells.

    Salient points for those who don’t want to read the article, or can’t:

    • The team administered a single shot of E. americana intravenously to mice with colorectal cancer, and it completely eliminated tumors in every treated animal.

    • Caused only short-lived inflammatory effects that resolved within 72 hours

    • Over two months of observation, treated mice showed no signs of organ damage or chronic toxicity.

    • The bacterium are also sensitive to antibiotics, providing intervention options if problems were to arise following treatment.

    • When the mice were later re-exposed to cancer cells, none developed new tumors, suggesting the treatment had triggered long-lasting immune memory.

    This holds some real promise, I’m very excited to see what this brings! Kudos to the researchers!

    If this takes off it could be a great thing for conservation. Frogs are in a lot of trouble!

    Sadly I’m not so sure, but I like to be optimistic

      What’s more, the response wasn’t just rapid but appeared to provide ongoing protection. When the mice were later re-exposed to cancer cells, none developed new tumors

      Apparently it made them stronger

        Please stop praying for my mice, they’ve become too strong. One of them chewed through the fridge

      Quite the contrary…

      first, it has a natural affinity for the low-oxygen environment inside solid tumors, so within just 24 hours it had increased its numbers by around 3,000-fold, but it also didn’t drift over to impact any other healthy organs or tissue. Then it’s able to directly kill the growth thanks to toxins it secretes inside the tumor.

      At the same time, the bacterial invasion triggered a natural immune response, and the tumors soon became flooded with immune cells – particularly neutrophils, and T and B cells – alongside increases in inflammatory signaling molecules. The combined effect was widespread tumor cell death driven both by direct bacterial action from the foreign gut bug and by the host’s own immune system.

      Importantly, this mechanism appears to also be highly tumor-specific, with E. americana sticking only to the tumor environment. The researchers believe this selectivity arises from a combination of factors unique to tumors – insufficient oxygen (hypoxia), leaky blood vessels, altered metabolism and locally suppressed immune defenses that allow the bacterial colony to thrive where they are also most destructive.
