You've heard of nanotech, right? It's basically working with things that are really, really tiny.*

When you zoom into something to a super small scale, really surprising things can happen.

Take gold. We like it because it lasts a lifetime (and longer)! It makes good watches, rings, and coins because it doesn't react with oxygen and become tarnished or corroded. It just sits there, a gleaming symbol of never-ending love and power.


But if you zoom in much, much more closely to a tiny particle of gold, it transforms to something very different!

One of your grandparents can wear a gold ring that doesn't change in a lifetime. But up close, gold becomes a much more exciting scene.

Scientists have been able to attach molecules of drugs to surfaces of gold at this scale and use gold as a delivery vehicle to take medicines to particular sites in the body. Vroom!

Rod-shaped nano gold particles can be loaded up with antibodies that bond only to cancer cells. The nano gold can by made to oscillate via infrared light until — boom! Bad day for cancer cell.

Zoom in even farther, and things get really weird.

Super tiny pieces of gold can be used to change carbon monoxide to carbon dioxide. That kind of magic suggests that maybe we can use gold to make better breathing apparatus for fire fighters, for example, or to purify water.

We're already surrounded by products using nanotech. Nano silver in clothing and packaging fights bacteria that makes things stinky. Nano titanium dioxide makes sunscreens, paints, and other coatings more reflective, helping shield your body and your house from the sun.

These wondrous tiny things can also easily pass through cell membranes, taking new materials where they've never gone before. So, like with all new technologies,we do want to be careful to research the risks as well as the benefits as we develop and deploy it.

That said, the future looks pretty sparkly for nano gold!

FIRST students learn real-world career skills through robotics competitions.

True

In today’s rapidly changing world, most parents are concerned about what the future looks like for their children. Whether concerning technology, culture, or values, young people today are expected to navigate—and attempt to thrive in—a society that’s far more complicated than that of their parents. It’s one of the reasons why parents are keen to involve their kids in activities that will help them become more resilient, well-rounded and better prepared for life when they enter adulthood.

One such activity is FIRST®, a volunteer-based global robotics community that helps young people discover a passion for science, technology, engineering and mathematics (STEM) through exciting, multifaceted challenges. FIRST helps kids ages 4 to 18 to build confidence, resilience, cooperation and empathy as they compete and collaborate with one another.

You may have seen the transformative power of FIRST programs featured in the new 2022 Disney+ documentary “More Than Robots.”

Three people engaged in conversation at a party.

There are some people who live under the illusion that everything they say is deeply interesting and have no problem wasting your time by rambling on and on without a sign of stopping. They’re the relative, neighbor or co-worker who can’t take a hint that the conversation is over.

Of all these people, the co-worker who can’t stop talking may be the most challenging because you see them every day in a professional setting that requires politeness.

There are many reasons that some people talk excessively. Therapist F. Diane Barth writes in Psychology Today that some people talk excessively because they don’t have the ability to process complex auditory signals, so they ramble on without recognizing the subtle cues others are sending.

It may also be a case of someone who thinks they’re the most interesting person in the conversation.

A leaping border collie.

Pet hotels have come a long way from the gloomy dog kennels that were once the norm. But apparently there's still no substitute for the comfort of home. In a delightful and downright impressive story from Inside Edition, Jeremy and Sarah Henson had their five-day Las Vegas vacation disrupted last February when they got an alert that their Ring doorbell had been pressed. Who was at their door? It was none other than their dog Dexter who they had recently boarded at a local pet hotel.

The Lenexa, Kansas couple must have been completely shocked that the dog escaped the pet hotel, made his way home and knew how to ring the doorbell. “We were both like, ‘Oh my God, that’s Dexter!’” Jeremy told Inside Edition. “Obviously, he didn’t understand the fact that we were gone, he just thought that we were home. And he takes his job protecting us very seriously."
