Polymetallic nodules litter a stretch of ocean between Mexico and Hawaii. They contain metals, such as manganese and cobalt, that mining companies want to use for battery production. Researchers recently found that these seafloor blobs might make their own oxygen—and no one knows exactly how. Scientific American ’s associate news editor Allison Parshall explains the hype behind this “dark oxygen.” Recommended reading: ‘Dark Oxygen’ Discovered Coming from Mineral Deposits on Deep Seafloor https:/...

Debris from satellites, rockets and other space infrastructure are crowding low-Earth orbit. Occasionally, that space junk crashes down to Earth. For Samantha Lawler, an associate professor of astronomy at the University of Regina in Saskatchewan, such debris was mostly a theoretical nuisance. Then a nearby farmer found remnants of a SpaceX craft on his land, and Lawler was pulled into the murky legal landscape around space junk in the skies and on the ground.

The American Cancer Society published a study suggesting that for 8 or 34 cancers tracked, case rates are rising from one generation to the next. While headlines often point to sedentary lifestyles and higher weights as a possible cause, some experts say that these factors alone cannot explain the spike. In more hopeful oncology news, there’s a new blood test for colorectal cancer–though it doesn’t replace the importance of colonoscopies. SpaceX is delaying their attempt at the first-ever privat...

Fish trapping is an ancient practice, reaching across the globe from at least as far back as 11,000 years ago. It takes advantage of coastal tides and human-made chambers to catch and release fish. The simple but ingenious ancient fishing structures are built on two intertwining principles: the ocean can provide for us if we properly care for it. Archaeologists are mapping the possible locations of ancient traps. And on Penghu, a group of islands off of Taiwan, people are reviving the traditiona...
