    That's what I had been wondering for quite a while.

    So 2020 really is the year anything can happen

    So now we can get Brownian motion to do work?

    WTF?

    Astounding. I would have been confident in saying this was pure fantasy. I hope I can eventually grok how this doesn't violate known laws of physics.

    Shows what I know. The possible applications are vast.

    It's the same randomness factor as getting a native North Carolinian to actually to work around these parts. In fact, I'd put my money on the Brownian concept...

    Don't worry, we don't expect too much from Yankees. Y'all do your best.

    "I promise we're not breaking the second law of thermodynamics" is a fun headline, most years...

    I'm taking what I can get in this year that resembles looking down the barrels of a double-barreled shotgun in more ways than one.

    Looks a lot like the Cassimir Effect. Both work, but presently only at nanoscales. The technology needed to move both into macroscopic feasibility is gonna cost YUGE.

    Jennifer Doudna, of UC Berkeley, won the Novel Prize for Chemistry. Her lab developed CRISPR technology for genome editing. It says something about how important CRISPR is that it's not even that old, but its discoverers are getting Nobel Prizes.

    In that spirit: A Historical Epidemic Has Been Making a Scary Comeback Due to a Bacterial 'Clone'


    "Once a leading cause of death for children across the western world, scarlet fever was nearly eradicated thanks to 20th century medicine. But fresh outbreaks in the UK and North East Asia over recent years suggest we've still got a long way to go.
    Just why we're experiencing a resurgence of the deadly pathogen is a mystery. A new study has uncovered clues in the genome of one of the bacterial strains responsible, showing just how complex the family tree of infectious diseases can be."

    "After 2011, the global reach of the pandemic became evident with reports of a second outbreak in the UK, beginning in 2014, and we've now discovered outbreak isolates here in Australia," says University of Queensland molecular biologist Stephan Brouwer.
    "This global re-emergence of scarlet fever has caused a more than five-fold increase in disease rate and more than 600,000 cases around the world."

    "One way similar organisms can evolve the same characteristics – such as advanced virulence – is for natural selection to independently fine-tune shared genes in the same way.
    But other studies have already suggested this strain of bacterium received a helping hand in the form of an infection of their own, one from a type of virus called a phage.
    "The toxins would have been transferred into the bacterium when it was infected by viruses that carried the toxin genes," says bioscientist Mark Walker, also from the University of Queensland."

    "In a process known as horizontal gene transfer, a gene that evolved in one microbe can be incorporated into a virus's genome and edited into a new host's DNA, creating a kind of clone of the original.
    Though hardly limited to bacteria, it is a quick and handy way for single-celled microbes to adapt. Such stolen genes can provide pathogens with new ways to gain entry to host tissues, or resist the chemical warfare that would otherwise keep them at bay.
    In this case, it has helped a less serious strain of bacteria to develop a weapon that makes it as concerning as its vanquished cousin."
