Astronomers trace mysterious blast of X-rays to 'Die Hard' star that refuses to perish (video)

If you're sweating through another scorching summer, Dyson's TP07 fan-purifier combo might be your new best friend—it cools your space while scrubbing the air of dust and allergens. Even better? Amazon’s Prime Day deal slashes its price by 43%, matching last year’s Black Friday steal.

Editor’s Note: Summer heatwaves aren’t just uncomfortable—they’re expensive if you’re blasting the AC nonstop. A gadget like this merges relief with air quality fixes, and the discount makes it a rare win for budget-conscious shoppers who want premium tech without the premium price tag.

Scientists have uncovered evidence of ancient river systems stretching over 10,000 miles across Mars’s southern highlands—a region previously thought to be dry. These riverbeds, dating back more than 3 billion years, suggest the planet was once much wetter than we imagined, reshaping our understanding of its watery past.

Editor’s Note: This isn’t just about dusty old riverbeds—it’s a big clue in the puzzle of whether Mars could have supported life. If water was more widespread than we realized, the chances of finding signs of past (or even present) microbial life go up. Plus, it helps us picture what Mars looked like billions of years ago: less barren desert, more flowing rivers. For future missions, that means targeting new spots where life might have left traces.

The U.S. is seeing the highest number of measles cases since the disease was officially declared eliminated in 2000. Health experts are sounding the alarm, warning that declining vaccination rates could turn these outbreaks into a recurring—and dangerous—trend.

If you've been thinking about joining Sam’s Club but didn’t want to shell out the usual $50 for a membership, now’s your chance to grab it for just $20—but you’ve only got four days left. This deal lets you save upfront so you can put more cash toward summer plans (or bulk groceries, obviously).

Editor’s Note: Warehouse memberships like Sam’s Club can be a great way to save on everyday essentials, but the upfront cost can be a turnoff. A limited-time discount like this makes it way more accessible, especially if you’re budgeting for summer trips or gatherings. Plus, timing it before peak shopping seasons (hello, back-to-school and holidays) means you’ll get more bang for your buck.

A sponsored post is pitching a pair of $90 mini night-vision binoculars with a playful (or maybe slightly tongue-in-cheek) angle: they’re framed as a tool for cryptid hunters or conspiracy theorists trying to spot creatures like the Mothman. The urgency of a "limited-time deal" is thrown in for good measure.

Editor’s Note: It’s a lighthearted ad masquerading as news—basically, "Hey, wanna play paranormal investigator on a budget?" While it’s not hard-hitting journalism, it taps into the fun, gadget-loving side of pop science culture. Just don’t expect these binocs to actually prove Bigfoot exists.
