Oh, to hear the top 10 songs of 2050

If I had a time machine, one of the first things I'd do with it is head for 2050, where I'd be so excited at the chance to hear the top songs of mid-century.

Unimaginable.

Consider today's top 10:

And then those of 1990:

No way to account for how we got here from there.

Magnetic spray turns tiny inanimate objects into insect-scale robots

From SyFyWire:

Does the idea of miniature, insect-scale robots swarming toward their intended duties inside your body make your skin crawl?

Medical researchers led by Dr. Shen Yajing from City University of Hong Kong (CityU) don't wish to alarm you but they've just devised a simple method of making millirobots which can be employed in various biomedical applications like targeted drug delivery and catheter navigation.

Their project seems remarkably simple when considering the results of coating tiny objects with a glue-like, magnetic spray.

As a result of the coated substance and driven by the corresponding magnetic field, these minuscule objects gain the ability to crawl, walk, creep, or roll along surfaces, in the future perhaps even inside the body.

The magnetic coating is completely biocompatible and can be dissolved into basic powders when necessary.

Working from facilities at the Department of Biomedical Engineering (BME) at CityU in a team-up with the Shenzhen Institutes of Advanced Technology (SIAT), and the Chinese Academy of Sciences (CAS), the scientists' findings were recently published in the online scientific journal Science Robotics.

Happy Twitter Anniversary

Zzz

On November 25, 2006 I joined Twitter.

It had gone live on July 15, 2006.

You could look it up.

I'm thinking there aren't a whole lot of us 2006ers still tweeting: most early adopter types whose joining dates I've glanced at seem to have come aboard in 2007-8.

I think the 14th anniversary is marked by Gray Cat hairballs — at least, that's how we're celebrating it.

Rain mStand

Way cheaper than a new laptop.

You're one knocked-over coffee swamping your keyboard from buying a new machine.

Sure, you'll want a desk-level wireless keyboard to make it easy to use your new machine.

Add that to the price of the stand and compare them to your new laptop's cost.

But wait — there's more!

Using the stand will markedly improve your ergonomics, lessening the likelihood of neck/back/shoulder discomfort/fatigue/strain.

And it's a nice looking piece of functional architecture.

What's not to like?

I have three: one for my MacBook Air alongside the one for my iPad Pro in one room and another atop my treadmill workspace, elevating my mid-2012-so-no-Big Sur MacBook Pro's screen to eye level.
