    Can gain of function cause them to pass the fungus to humans . Her Doctor Fauci has not weighed in yet.

    But if I see one of them ,I'll just stomp on them.

    The biggest nightmares are still human induced . Things like drones .

    A very expensive Blackhawk helicopter got downed by a cheap drone in Columbia. Drone warfare is now a global phenonium

    The CNP helicopter was hit by a drone while “providing security to officers engaged in manual coca crop eradication efforts,” Antioquia Governor Andres Julian Rendon stated on X. “We have activated the hospital network and are closely monitoring this news, which is so painful for democracy and sad for our Forces. In that area, FARC dissidents and the Gulf Clan are operating.”

    Cartels , Rebels and Terrorists have got their hands on them .

    A drone attack on a U.N. convoy set fire to all 16 trucks carrying desperately needed food to Sudan’s famine-hit North Darfur region and destroyed all the vehicles, the United Nations said Thursday.

    But for us the problem is the Cartels have adopted drone strategy in out border war .

    Testifying this week before the Senate’s Judiciary Committee, Willoughby said federal authorities since the start of July to the end of December 2024 detected 60,000 such drone flights just south of the border and 27,000 unique remote-controlled craft doing the flying.
    Most of those drones are going up at night or flying at altitudes that are restricted in both Mexico and the United States. That’s 400 feet high in the U.S. and 120 meters in Mexico. That’s enough to give Mexican drone operators a clear view of U.S. Border Patrol agents’ location and movement, send migrants north in a different direction or find places to drop drugs for later pickup.

    In Star Wars the Ewoks used primitive inexpensive items to defeat the weapons of the Empire . In our world the drones are the bows and the rocks ,the rope between the trees.

    Your observations about drones, and in particular those in the hands of the drug cartels who have plenty of cash to purchase and develop them, are certainly alarming. We can only hope that the Defense Dept. is working with the border patrol to counter these. I would think that some sort of jamming would be effective.

    Easier said than done. RF jamming can be overcome with frequency hopping.

    Then defense requires a knowledge of what frequency is being used and when and where (the border is big) ,

    Also the jammer has to be aware that by jamming they become targets as they also emit RF .

    On the Ukraine front they swarm the drones expecting a percentage of them to fail. But they are cheap .

    The same is true for the RF controller of the drone. These problems are generally overcome, I would think, by putting the antenna for transmitting some distance away from the controller. Antennae are cheap.

    Between drones and hypersonic anti-ship ballistic missiles (ASBMs) the era of projecting power with an expensive carrier surface fleet is over. The navy that dominates the sub surface will rule.
