Remora fish attach to sharks, whales, turtles, boats, and even divers to survive. We studied remoras to figure out how they attach themselves using a disc on the top of their head. We wanted to find out if we could copy the disc to make suction devices that can work in other wet environments. Using our findings, we created a device that can attach to a variety of surfaces. It also worked under a variety of conditions. For example, it stayed attached inside the stomach of live animals for almost 3 weeks! This device could help us track conditions and deliver medicine inside the human body. It could also help us track the environment around us.You are one of half a million educators in the U.S. who use our articles and videos in class.

But how does your brain know which food caused the problem? We wanted to find out. We studied this question in mice. First, we gave them a sweet drink with a flavor that was either new or familiar. Then, after a short delay, we caused mild sickness and looked at their brains. The amygdala, a brain area for memory, “replayed” the flavor signal when the stomach sent the sickness signal. This replay made the memory stronger. Mice then avoided the new flavor that made them sick, but not the familiar flavor that hadn’t made them sick in the past. This shows how the brain bridges the gap between eating and later feeling sick.You are one of half a million educators in the U.S. who use our articles and videos in class.

Leaders had to make fast choices. But how did they know what to do? We looked at the work of a team of scientists from Imperial College London. They helped by sharing reports, news stories, and science papers – fast. We looked at 620 reports they put out between 2020 and 2022. We were curious. What types of reports did they produce? How fast did they share their work? Who used it? What did they study?News stories reached leaders the fastest. About two months faster than normal science papers. That matters when people are getting sick! Reports and preprints were also created by the team. Governments from 41 different countries cited work from the team as they developed policy. The team also changed what they studied as the virus changed. This made their reports more useful for governments. Our study shows something important: sharing science quickly can help develop policy that keeps people safe.You are one of half a million educators in the U.S. who use our articles and videos in class.

Predators try to catch prey, while prey try to avoid predators. Predators can blend into their surroundings and wait for prey to get close. Or predators can chase their prey. Some predators will even sneak up on their prey before chasing it. Camouflage can help these predators be more successful.One predator that uses camouflage is the cuttlefish. But we don’t know much about how they hunt in the wild. So, we observed broadclub cuttlefish on coral reefs in the Indo-Pacific. We saw four different hunting displays. We also saw individual cuttlefish using multiple displays in different moments. This information can help us better understand predator behavior on coral reefs.You are one of half a million educators in the U.S. who use our articles and videos in class.

Well, some sea snails are doing exactly that! We were curious about Kellet’s whelks, a type of sea snail. They usually live in the warm waters of Southern California and Mexico. Now, we’re finding them further north in colder water! We collected Kellet’s whelks from the California coast – some from the south and some from the north. We kept them in separate tanks with identical conditions. Then we compared the DNA of their babies.The northern snails had 2,770 genes that were working differently. These differences were so clear that we could tell if a baby snail’s parents came from the south or north just by looking at its DNA. We also found that the northern snails’ genes show some changes that help them survive in the colder water up north! Our findings are helping scientists understand how ocean animals are adapting to a changing climate.You are one of half a million educators in the U.S. who use our articles and videos in class.
