This week's science news was awash with alarming updates from the world's oceans, with the National Oceanic and Atmospheric Administration declaring the official onset of El Niño.
El Niño is the warm phase of a multiyear natural climate pattern in the Pacific Ocean that supercharges temperatures across the globe, and this one is looking to be particularly strong, earning it the unofficial moniker of a "super" El Niño. Just how intense is it? It will likely become the strongest in history, most climate models predict, and it may have profound effects on rainfall, wildfires and agricultural yields across the planet.
Jumping from the Pacific to the Atlantic, we also reported on a growing "cold blob" south of Greenland that could signal the slowing of ocean currents that are vital to the Northern Hemisphere, just as the Trump administration decided to remove the deep-sea instruments that monitor it. And farther into the Arctic, we also covered news that the region had crossed a critical biological tipping point.
If all that seems a little grim, one story also reminded us that a marine death isn't always the end; sometimes, it's the beginning of a sea change, as evidenced by the discovery of a 5 million-year-old whale graveyard that stretches for hundreds of miles, making it a "megasite" for other life-forms in the Indian Ocean.
Artemis III crew revealed
The Artemis III crew from left to right: Andre Douglas, Luca Parmitano, Randy Bresnik, and Frank Rubio
(Image credit: NASA)Less than two months after the triumphant splashdown of the Artemis II astronauts, NASA announced the crew for its next step toward the moon, which the agency is touting as one of its most complex yet.
NASA's Randy Bresnik will serve as commander, the European Space Agency's Luca Parmitano will be the pilot, and NASA's Andre Douglas and Dr. Frank Rubio will be the crew's mission specialists. They will launch into low Earth orbit in 2027 as part of a mission to test commercial lunar landers before 2028's scheduled return to the moon.
Yet most of the drama of this mission is taking place before it has even launched, with the two private companies commissioned by NASA to develop a lander — SpaceX and Blue Origin — suffering some explosive setbacks in recent weeks. What that means for the mission remains up in the air.

Was your water once peed out by an animal?
(Image credit: Monica Murphy via Getty Images)How much pee have you drunk in your lifetime? Your answer is almost certainly little to none, at least on purpose. But what if all the water you drink is the product of urination? It turns out this disturbing question is controversial even among scientists, Live Science's deep dive reveals.

Ancient corpse's arms turned into tools
The inside of the skull of Individual 1 shows cut marks, possibly made during brain removal.
(Image credit: Castells Navarro et al. / Antiquity Publications Ltd.)A new analysis this week revealed that a woman buried in the far North of Scotland had her brain scooped out and her arms whittled into tools.
Exactly what explains the unusual burial ritual remains unclear, according to the archaeologists who studied the remains. "However, the care with which she was reassembled and deposited in the cairn possibly suggests she commanded a level of reverence and respect by her community," said Laura Castells Navarro, an archaeologist at the University of York in the U.K. and part of the team.
Beyond the baffling and grisly finding, the team conducted a DNA analysis that found connections with individuals buried at sites across ancient Scotland, suggesting the people maintained complex social relationships across vast distances.

This particular image is a long exposure captured by photographer Daniel Viñé Garcia over a salt flat in Argentina's arid Catamarca province. The brightest stars can be seen reflected in the turquoise, briny pools at the bottom.
