Scientists uncover Earth's oldest rocks in Canada, dating back 4.16 billion years, while also retracing a 30,000-year-old ocean voyage in a hollowed-out log, revealing groundbreaking insights into ancient Earth and human exploration.

Scientists Retrace 30,000-Year-Old Ocean Voyage, in a Hollowed-Out Log

The New York TimesWednesday, June 25, 2025 at 6:00:13 PM
A team of Japanese scientists decided to put themselves in the shoes—or rather, the dugout canoe—of ancient humans by recreating a 30,000-year-old ocean voyage. Using a hollowed-out log, they tackled the same treacherous currents that early seafarers might have faced, testing theories about how our ancestors pulled off these daring migrations. It’s part of a hands-on approach called "experimental archaeology," where researchers don’t just study artifacts—they try to relive history.
Editor’s Note: This isn’t just a quirky science experiment—it’s about solving one of humanity’s oldest puzzles: how people first crossed vast oceans without modern tech. By literally getting their feet wet, these researchers are uncovering clues about human ingenuity and resilience. It’s a reminder that sometimes, to understand the past, you’ve got to dive in (figuratively and, in this case, literally).

15 years before Helldivers 2, Lost Planet 2 taught us that the only good bug was a dead bug
positiveScience
Before "Helldivers 2" became the go-to game for bug-stomping chaos, "Lost Planet 2" was quietly laying the groundwork back in 2010. This underrated Capcom sequel nailed the thrill of teaming up to blast alien hordes—proving that cooperative, large-scale monster battles could be a blast. It didn’t get the love it deserved at the time, but its DNA is all over today’s hits.
Editor’s Note: If you’ve ever laughed maniacally while mowing down swarms of enemies with friends in a modern shooter, you might owe a nod to "Lost Planet 2." This piece is a fun reminder that today’s gaming trends often stand on the shoulders of overlooked gems—and hey, maybe it’s time to revisit this cult classic.
Rocks in Canada may be oldest on Earth, dating back 4.16 billion years
positiveScience
Scientists have identified rocks in Canada that might be the oldest ever found on Earth—clocking in at a staggering 4.16 billion years old. If confirmed, these ancient formations could give us a rare glimpse into our planet's earliest crust and the conditions that may have set the stage for life to emerge.
Editor’s Note: This isn’t just about breaking records—it’s about peering into Earth’s infancy. Understanding these rocks could help piece together how our planet evolved from a molten ball into a habitable world. For anyone curious about the origins of life or how Earth got its start, this is like finding a time capsule buried in the planet’s basement.
See the crescent moon dance with Mars and the bright star Regulus this weekend
positiveScience
This weekend, skywatchers are in for a treat as the crescent moon will appear to cozy up to Mars and the bright star Regulus. Some viewers might even catch the moon sliding right in front of Mars—a rare celestial handshake. Grab your binoculars or just step outside; no fancy equipment needed for this show.
Editor’s Note: Events like this remind us how dynamic our night sky is—no apps or subscriptions required. It’s a free, fleeting spectacle that connects us to the cosmos, perfect for sparking wonder or even a late-night conversation with neighbors. Plus, it’s a gentle nudge to look up from our screens once in a while.
Elusive and critically endangered leopard caught on camera
positiveScience
A critically endangered leopard—so rare it’s barely been seen in years—was just captured on camera in Bangladesh. This isn’t just a lucky wildlife snapshot; it’s proof that these elusive big cats are still hanging on in the region, giving conservationists a glimmer of hope.
Editor’s Note: For a species teetering on the edge of extinction, every sighting is a big deal. This photo isn’t just cool—it’s evidence that conservation efforts might be working, or at least that there’s still a chance to save these leopards. It’s a reminder that even in shrinking habitats, nature still has surprises up its sleeve.
Nozzle blows off rocket booster during test for NASA's Artemis program (video)
negativeScience
During a recent ground test for NASA's Artemis moon missions, a critical part of a solid rocket booster—the nozzle—blew off unexpectedly. The incident, caught on video, happened during a routine static fire test at Northrop Grumman’s facilities. While no one was hurt, it’s a hiccup for the Space Launch System (SLS), the rocket meant to power astronauts back to the lunar surface.
Editor’s Note: Rockets are complicated beasts, and testing them is supposed to uncover flaws before they’re airborne. This mishap doesn’t spell doom for Artemis, but it’s a reminder that even "routine" tests carry risks—and delays. With NASA racing to return humans to the Moon by 2026, every setback matters. The silver lining? Better to blow a nozzle on the ground than in flight.
