Re: What is your outlook?

Question: Are you generally optimistic or pessimistic about the way the world is headed?

Transcript:Well I’d like to think that I’m realistic which means that the optimism is only justified if a few people take very strong action, sometimes putting themselves or their careers at risk. And then you will see this positive feedback loop where more people get inspired by this, and I mentioned some of the people that have inspired me, that have taken their family’s disease and become healthcare activists. If we have a few activists, it doesn’t have to be everybody, but everybody should join with them in doing their little part. So I think that would lead to optimism, but I’m not going to be blindly optimist. We need to have activists and people who get inspired by activists.

Within the year, Church says, people will have affordable access to their genetic information.

“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.
