A whale's first breath on camera, and whirlpools hiding on the Sun

That is roughly the resolution needed to spot a one euro coin from 180 kilometers away. The vortices form along the fringed edges of granules, the bubbling convection cells (500 to 2,000 kilometers wide) that make the Sun's surface look like a pot of boiling liquid, and they swirl and break like ocean waves cresting. The team thinks these tiny whirlpools twist magnetic field lines and may feed the small eruptions called nanoflares, and could help explain why magnetic energy spreads through the Sun's atmosphere faster than current models predict.

Then a plume of red bloomed in the water, and a small pale calf surfaced for its first breath. Forrest called in fellow drone operator Tanya Snowden, of the Organization for the Rescue and Research of Cetaceans in Australia, and the pair spent hours documenting the mother's protective circling and the calf's clumsy first attempts to stay near her, sometimes drifting three meters off. Only three other humpback births have ever been documented in scientific records, and none from the air.

The effect shows up in humans but not in mice or other lab primates, which is part of why nobody caught it until now. The work, published July 30 in Nature, builds on an earlier finding that certain mutant blood stem cell clones lower Alzheimer's risk, suggesting these migrating cells actively reshape the brain's disease trajectory rather than just topping up old ones.

That human trend didn't reach statistical significance on its own, but animal experiments filled the gap: EGCG, green tea's signature compound, restored the brain's cellular recycling system and preserved memory in obese mice by cutting inflammation.

Every flu shot Americans have gotten since the 1940s has been grown in fertilized chicken eggs, a process that takes six months and locks in strain choices made months before flu season even starts. Flu is no small thing: the 2024-25 season alone caused 51 million illnesses, 710,000 hospitalizations, and 45,000 deaths, more than US car crashes that year, and the week after infection carries roughly six times the normal heart attack risk.

This year, Fota Wildlife Park in County Cork successfully fledged a chick, its first in over a decade, hatched April 13 to parents Áine and Tony, who fed their eight-foot-wingspan offspring up to 21 ounces of food a day through the breeding season. Ireland's wild sea eagle population is now considered self-sustaining.

In February 2021, Australian campaigner Joey Carbstrong began investigating the site, ultimately obtaining what he describes as the first footage ever captured from inside a working UK pig gas chamber. The Guardian published the investigation in May 2023, and Pilgrim's closed the site shortly after. This week, drone footage confirmed the demolition is complete: the building, and the gas chamber inside it, is now rubble.

Every night, teams pull on reflective jackets, grab torches and megaphones, and walk the fields until the herds pass safely through, sometimes until midnight, sometimes until sunrise. Their job isn't to drive the elephants away; it's to make sure neither elephants nor people get hurt as ancient migration paths, remembered across elephant generations through the matriarch's memory, keep colliding with modern farmland.
