These bubbles kill cancer

2023-10-06 Jim Lynch

The process [of histotripsy] uses a transducer—which converts electricity into sound—to deliver ultrasound waves to a malignant mass at a precise location. When the waves hit gasses inside cancerous cells, they generate clouds of tiny bubbles through a process known as cavitation.

Pulsing sound waves causes the millimeter-sized bubble clouds to repeatedly grow and collapse. On an ultrasound monitor, it can look like bubbles from boiling water—quickly rising and falling along the surface in your pot.

In the past, researchers saw the creation of bubbles through ultrasound as “uncontrollable,” something to be avoided. Histotripsy, however, generates mechanical energy to activate those bubble clouds and break up the tumor cells’ structure, turning it into a liquid called acellular lysate.

histotripsy foils cancer’s cloaking efforts by destroying its cell walls, leaving the tumor antigens in plain sight for the body’s immune system.

What Are Dreams For?

In a series of papers, Blumberg articulated his theory that the brain uses REM sleep to “learn” the body. You wouldn’t think that the body is something a brain needs to learn, but we aren’t born with maps of our bodies

In 2013, Blumberg published a paper in Current Biology titled “Twitching in Sensorimotor Development from Sleeping Rats to Robots.” In it, he asked, “Can twitching, as a special form of self-generated movement, contribute to a robot’s knowledge about its body and how it works?”

A Thought on the Lovelace Test

The Lovelace test demands of a computing machine that it not only produce an artifact that is by conventional standards amazing, but it leaves everyone looking at it
stupefied as to how it does what it does: including in this stupefaction the creators and designers of the machine.
– Selmer Bingsjord [1]


An artificial agent, designed by a human, passes the [Lovelace] test only if it originates a “program” that it was not engineered to produce. The outputting of the new program—it could be an idea, a novel, a piece of music, anything—can’t be a hardware fluke, and it must be the result of processes the artificial agent can reproduce. Now here’s the kicker: The agent’s designers must not be able to explain how their original code led to this new program. [2]


My thought is if God made humans, can a human use creativity to make an artifact, so that God can’t explain how it was made?

Most surgeries are ineffective

2021-01-21 Paras Chopra

surgery is different than medicine. All new pharmaceutical molecules are subjected to rigorous clinical trials where they’re tested against placebo or doing nothing. In many countries, there’s no such procedure for surgical treatments. If there is a procedure for new surgical procedures, nobody is testing old ones that have been getting performed every day without evidence.

The Most Famous Paradox in Physics Nears Its End

2020-10-29 George Musser

In a series of breakthrough papers, theoretical physicists have come tantalizingly close to resolving the black hole information paradox that has entranced and bedeviled them for nearly 50 years. Information, they now say with confidence, does escape a black hole. If you jump into one, you will not be gone for good. Particle by particle, the information needed to reconstitute your body will reemerge.
