How do birds find their way during migration: A look at their navigation system

Norma Swenson, a pioneering co-author of Our Bodies, Ourselves—the groundbreaking book that demystified women’s health and empowered generations—has passed away at 93. A fierce advocate for natural childbirth and bodily autonomy, she helped transform a grassroots project into a global phenomenon that challenged taboos and gave women the tools to take control of their health.

Scientists have finally tracked down a huge chunk of the universe's "missing" matter—not dark matter, but the regular kind that’s been mysteriously absent from our cosmic accounting. They did it by studying fast radio bursts (FRBs), those bizarre, ultra-powerful blips of energy from deep space. As these bursts traveled through the "cosmic fog" between galaxies, their signals revealed hidden pockets of matter that had eluded detection for decades.

Editor’s Note: For years, scientists knew there was more ordinary matter—protons, electrons, and the like—out there than we could actually see. Now, thanks to FRBs acting like cosmic flashlights, we've found it hiding in the vast, sparse regions between galaxies. This isn’t just a win for astronomy; it’s a big step in understanding how the universe is structured on the largest scales. Plus, it’s a reminder that even the emptiest-looking parts of space aren’t quite as empty as they seem.

Mathematicians have stumbled upon a surprising new pattern for identifying prime numbers—those elusive digits that can only be divided by 1 and themselves. By using a concept called integer partitions (which, in simple terms, is about breaking numbers into sums of other numbers), they’ve not only found a fresh angle for spotting primes but also bridged two seemingly unrelated areas of math. It’s like discovering a hidden tunnel between two distant mountains.

Editor’s Note: Primes are the building blocks of math, and cracking their code has big implications—from cryptography to computer science. This discovery isn’t just a neat trick; it’s a reminder that even in well-trodden fields, there are still mysteries waiting to be unraveled. For math nerds and tech folks alike, it’s a thrilling "aha" moment.

Three big stories today: First, RFK Jr. shook up the CDC's vaccine advisory panel by firing several experts—raising eyebrows about future public health guidance. Meanwhile, scientists warn that ocean acidification has now hit levels that could seriously harm marine ecosystems. And in wildlife news, pangolins—already the world's most trafficked mammals—face a surprising new hunting threat that could push them closer to extinction.

Editor’s Note: These stories all point to growing instability in systems we rely on, whether it's vaccine policy, ocean health, or biodiversity. The CDC panel changes could fuel distrust in public health, acidification threatens fisheries and coastal economies, and pangolins are a bellwether for the broader extinction crisis. Basically, it's a rough day for people who care about science and nature.

Turns out, the world's oldest dress isn’t some ornate royal gown—it’s a humble linen V-neck that spent years being mistaken for rags. Dubbed the Tarkhan Dress, this 5,000-year-old garment was actually worn to an ancient Egyptian funeral, making it a rare glimpse into everyday life (and death) in one of history’s most fascinating civilizations.

Editor’s Note: While pyramids and pharaohs dominate Egypt’s headlines, this wrinkled relic reminds us that ordinary people had stories too. It’s a tangible link to how regular folks dressed, mourned, and lived millennia ago—proof that history isn’t just about treasure, but also the quiet, overlooked details.
