A New Ice Age Was Beginning. Then Humans Started Burning Fossil Fuels

Ancient plants reveal that the vestiges of the North American ice sheet started expanding a few thousand years ago, but that climate change caused it to reverse course.

Spooooooky! Alaskan man makes terrifying ‘kelp-o’-lanterns’

It seems like Halloween decorations are getting more elaborate every year. Instead of a viral 12-foot skeleton, a digital creator in Alaska has turned to nature to find inspiration for his spooky embellishments. In 2025, photographer and Homer resident Tim Hatfield was walking on a beach with his girlfriend. They noticed that some strands of bull kelp (Nereocystis luetkeana) had washed ashore. Bull kelp, sometimes referred to as “mermaid’s bladder,” is a fast-growing annual seaweed that grows along much of the coast of North America.

Hatfield’s girlfriend pointed out that one of the pieces of kelp looked like a face, and said that she’d seen them used as Halloween decorations before. Hatfield decided to give it a try himself, and returned to the beach after a big storm to bring some home. He then turned the bull kelp remains into eerie faces, added lights, and even fashioned one into an eyeball. “The coolest thing about the kelp-o’-lanterns is that as they age, and it only takes a few days, they look creepier and almost look like real shrunken heads,” Hatfield tells Popular Science. “Then this year I kind of already went for the ones that looked weathered.” The kelp-o-lanterns will only get creepier the closer it gets to Halloween.

This year’s kelp-o’-lantern includes a one-eyed ghoul with a creepy spider-looking thing sticking out of its mouth and a noose around its neck, and an eerie looking head with two seemingly blood-stained tongues. Last year, Hatfield set up his kelp-o’-lanterns at his girlfriend’s house in town. For this year, the spooky decorations are staked out at his place. Hatfield’s house sits at the top of a hill, so trick-or-treaters on the hunt for c

New water lily can be seen from space

One cold December day in 2021, Colorado carnivorous plant grower Jeremiah Harris shared some pictures of wild Amazonian giant water lilies (Victoria amazonica) plants in the Inírida River in Guainía, Colombia to Instagram. There’s just one problem. No known Victoria water lily species grow there. When water lily expert Carlos Magdalena saw the post on Instagram, he suspected a new plant species could be involved. To investigate the matter, he used satellite imagery to remotely search the Inírida River and its surrounding lakes and confirmed the presence of Victorias. And yes, you can see these enormous plants from space. Victorias grow the world’s second largest single plant leaf. Victoria colombiana is the fourth Victoria water lily to be described. Image: Carlos Magdalena. Magdalena is a botanical and scientific research horticulturist at the Royal Botanic Gardens, Kew in the U.K. Along with his colleagues, the team went on a five-day expedition to Inírida. The team included members of the Indigenous reserves del río Atabapo, one of whom had seen the lilies during his childhood. However, the trip didn’t exactly go according to plan. By their last night, they had found only two water lily plants, neither of which had flowers. This was a problem, because botanists need a flower to differentiate species. As if that wasn’t bad enough, the water lilies they found seemed to be struggling with a late rainy season. But when Magdalena described their situation to the expedition’s boat captain, Gustavo Melo, he said he knew where they could find more of this water lily. They didn’t have much time to do so, with the team’s flight back to Bogotá was at 9:00 a.m. the next morning. Thus at 1:00 a.m., Melo, a member of the Indigenous Tucano community, led them to a small lake. There
