BAHAMAS

Biologists strapped small cameras onto tiger sharks to study seagrass in the Caribbean. The footage helped expand estimates of the global area of seagrass coverage by 41 percent—a good sign for the climate because seagrass stores carbon.

Scientists have struggled to identify the creatures that left behind the world’s oldest skeletal remains—500-million-year-old tubelike structures. Now a new analysis of specimens from Yunnan (including a rare look at their fossilized soft tissues) suggests the animals were jellyfish relatives that resembled sea anemones.

MALAYSIA

Researchers have produced stem cells using skin from Malaysia’s last male Sumatran rhinoceros, Kertam, who died in 2019. Converting these cells into viable spermatozoa could help to save the critically endangered animal from extinction.

MEXICO

Archaeologists unearthing an administrative complex of the ancient city Teotihuacán found the roughly 1,700-year-old skeleton of a spider monkey that was not native to the region. Experts suspect it was a gift from the neighboring Maya, pointing to previously unknown animal-based diplomacy.

REPUBLIC OF CONGO

A new study suggests the Congo peatlands have alternated—every few thousand years—between releasing carbon dioxide (when dry) and storing it (when wet). This may mean the peatlands are a climate change “time bomb” set to release stored carbon as they dry.

U.K.

A meteorite that landed in an English driveway has been found to contain water with a ratio of hydrogen isotopes resembling Earth’s. This supports the idea that the young Earth’s water could have been brought by asteroids.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
