Hay fever relief could come in the form of a nasal 'molecular shield'

If you've been eyeing a fancy electric toothbrush or a water flosser but didn’t want to pay full price, now’s your shot—Amazon’s Prime Day is wrapping up, and our health team has scoured the deals to highlight the best discounts for keeping your teeth sparkling. Act fast, though—these bargains won’t last.

Editor’s Note: Dental care gadgets can be pricey, but snagging one on sale means better oral health without the usual sting to your wallet. Since Prime Day is time-sensitive, this is a nudge to grab quality products before prices bounce back. Who doesn’t love saving money while investing in a healthier smile?

The US Space Force just kicked off its biggest training drill yet, simulating combat scenarios in orbit. The goal? To prove they're ready to defend American interests—and dominate—in the increasingly contested realm of space.

Editor’s Note: Space isn’t just for exploration anymore—it’s the next potential battleground. With rival nations expanding their space capabilities, this exercise signals how seriously the US takes orbital security. It’s less about imminent conflict and more about deterrence: showing rivals that messing with satellites or other space assets could have consequences. For everyday folks, it’s a reminder that the "final frontier" is getting crowded—and competitive.

If you've ever misplaced your keys, backpack, or even your telescope during a meteor shower, Apple's AirTag is currently 31% off on Amazon Prime Day—today’s the last chance to grab one at this price. With the Perseid meteor shower just around the corner, it’s a smart time to keep track of your gear while you’re out stargazing (or just navigating daily life).

Editor’s Note: Losing stuff is frustrating, and Prime Day discounts don’t stick around forever. This deal is especially handy for skywatchers or anyone who wants a little extra peace of mind—attach an AirTag to your essentials, and you’ll spend less time searching and more time enjoying the show (whether that’s meteors or just your morning commute).

Scientists are buzzing about a strange object called 3I/Atlas that zoomed into our solar system last week. Early clues suggest it might be the oldest comet ever discovered—possibly a frozen relic from another star system. Researchers are scrambling to study it before it vanishes into deep space.

Editor’s Note: If confirmed, this could be a once-in-a-lifetime chance to study a visitor from beyond our solar system up close. It’s like getting a cosmic time capsule delivered to our doorstep—except we don’t know who sent it or how old it really is. The more we learn, the more it could rewrite what we know about how comets form and travel between stars.

Sci-fi author Martha Wells, best known for her Murderbot Diaries series, thinks today’s AI—like the chatbots making headlines—isn’t even close to the sentient, self-aware machines we see in books and movies. She argues that current large language models are just sophisticated pattern-matchers, not the kind of conscious, rebellious androids she writes about.

Editor’s Note: With AI hype at a fever pitch, Wells’ perspective is a refreshing reality check. Her take matters because she’s spent years imagining what true machine intelligence might look like—and she’s saying we’re nowhere near it. This isn’t just a tech debate; it’s about how we frame our expectations (and fears) around AI’s future.
