Question: Is there a gap between diagnosis and treatment? Transcript: Well there’s two gaps there. One is a gap between our ability to diagnose and cure, and there’s other cases where they have the ability to cure but not diagnose the small set of people who react very negatively. Both of these, I think, are going to see major progress. They’ve already seen some major progress. But for example, different people have different responses to a personal decision. If you are offered the ability to get diagnosed for a disease for which there is no cure, some people say, “I don’t want to know that”. Other people say, “I want to know that, but I’m not going to do anything about it.” And the third set say, “Oh we’re gonna embrace this. We’re going to become experts on this disease,” even though they’re not even scientists. They become experts. Think of Lorenzo’s Oil where Augusto Odone actually starts to learn biochemistry and himself makes a contribution to lipid disorders . . . makes a new drug-like, food-like molecule. But there are many cases of this where people become the poster . . . . their family will become poster children for the disease: Michael J. Fox for Parkinson’s, and Doug Melton for Diabetes, and Betty Ford for cancer and substance abuse, and so forth. So I think that’s a really big opportunity is to take ownership of all the things that are special about your family, both positive and negative, and link up with other families that have the same alleles, the same changes in their DNA, the same variations that make them different from the average, and see how it plays out differently in different families. Maybe that some of them have much more severe traits than others, and you can find it by sharing that information. And you can see what lifestyle changes might be correlated with a less severe outcome. So I think that embracing things that don’t have cures, whether they’re severe or not, is an opportunity that we’ll see more and more.

“Acoustic tweezers” use sound waves to levitate bits of matter

The non-contact technique could someday be used to lift much heavier objects — maybe even humans.

Kondo and Okubo, Jpn. J. Appl. Phys., 2021.
Surprising Science
  • Since the 1980s, researchers have been using sound waves to move matter through a technique called acoustic trapping.
  • Acoustic trapping devices move bits of matter by emitting strategically designed sound waves, which interact in such a way that the matter becomes "trapped" in areas of particular velocity and pressure.
  • Acoustic and optical trapping devices are already used in various fields, including medicine, nanotechnology, and biological research.

Cockatoos teach each other the secrets of dumpster diving

Australian parrots have worked out how to open trash bins, and the trick is spreading across Sydney.

Surprising Science
  • If sharing learned knowledge is a form of culture, Australian cockatoos are one cultured bunch of birds.
  • A cockatoo trick for opening trash bins to get at food has been spreading rapidly through Sydney's neighborhoods.
  • But not all cockatoos open the bins; some just stay close to those that do.

    CT scans of shark intestines find Nikola Tesla’s one-way valve

    Evolution proves to be just about as ingenious as Nikola Tesla

    Surprising Science
    • For the first time, scientists developed 3D scans of shark intestines to learn how they digest what they eat.
    • The scans reveal an intestinal structure that looks awfully familiar — it looks like a Tesla valve.
    • The structure may allow sharks to better survive long breaks between feasts.

    Godzilla and mushroom clouds: How the first postwar nuclear tests made it to the silver screen

    The few seconds of nuclear explosion opening shots in Godzilla alone required more than 6.5 times the entire budget of the monster movie they ended up in.

    Culture & Religion

    As I sat in a darkened cinema in 1998, mesmerised and unnerved by the opening nuclear bomb explosions that framed the beginning of Roland Emmerich's Godzilla, it felt like I was watching the most expensive special effect in history.
