This opah is about as close to a full-body warm-blooded fish as science has yet discovered. Here, biologist Nick Wegner prepares to insert a temperture sensor into the animal’s pectoral muscles. The device will record internal and external temperatures following the fish’s release.
Dana Arabiyat, 15, of Amman, Jordan, designed a satellite (model shown) to collect and dispose of the space trash that threatens other satellites orbiting Earth.
Scientists measure carbon in sediment cores (seen here) drilled from the ocean floor. These cores show that extra carbon is being added to the atmosphere at a rate unmatched in 66 million years. Not even a massive outpouring of carbon 56 million years ago (the red band) comes close, a new study finds.
Whenever I'm near the ocean, I always feel as if I'm on vacation. I love the smell of salt in the air, the squawk of seagulls, and the sound of the waves as they lull me to sleep.
On a recent weeklong trip to Mexico, I learned to appreciate the ocean in a new way. As part of a camp for women run by a company called Las Olas, I spent up to 5 hours a day learning how to surf. I've always liked swimming and jumping through waves, but this was different.
NASA is supposed to begin nonstop screening by 2020 for all asteroids that could pose a threat to Earth. Some astronomers now think the only way to affordably meet that deadline is by using mini-satellites
Astronomers tracked down the source of perytons, mysterious radio bursts. They had at first seemed to emanate from Earth’s atmosphere. Probing now suggests the life forms responsible had a penchant for leftovers.
Unsightly plastic bottles, bags and other trash give just a hint of the largely unseen problem of plastic pollution. Scientists have found tiny bits of it throughout the ocean. The bad news: Sea life can’t tell the difference between plastic and food.
