Solar eclipses are dramatic events, as a rule. The moon moves between the Earth and the sun to block out our star. For a few minutes, the world around you will go eerily dark. But the total eclipse coming on April 8 is going to be more special than usual. The last total eclipse crossed…
Tiny plastic bits are everywhere — wafting in the air, riding ocean currents, raining down on plants and swirling in bottled water. The smallest of these — nanoplastics — have been hard for scientists to study. Now, researchers have developed a new method to identify these super-tiny bits, each billionths of a meter in size….
Roses are red and blueberries look blue. But the berry’s color is not really true. The fruit’s waxy coat just masquerades as blue. A waxy covering coats some blue-colored fruits — such as blueberries, dark grapes and certain plums. This wax contains a host of tiny structures, each less than a thousandth the thickness of…
Model (noun, “MAH-del”) A model is a representation of how something in the real world works. Scientists use models to ask questions, make predictions, explain phenomena and test our current knowledge. Scientists also use models to share their ideas with others. Some models are physical objects. A model airplane represents the shape and appearance of…
The world’s largest known group of octopuses can be found in a place called the Octopus Garden. It’s tucked against a seafloor hill off the coast of California. Here, thousands of pearl octopuses (Muusoctopus robustus) gather to breed. Scientists have wondered for years what drew so many pearl octopuses to this spot. Now, underwater cameras…
Ancient tiny fossils may hold early signs of a power that shaped the world. That power: photosynthesis. It released oxygen to help shape our atmosphere. Cyanobacteria are one of Earth’s oldest known life forms. They “invented” photosynthesis billions of years ago. The new fossils, found in Australia, are from cyanobacteria. Like plants, these microbes make…
Have you noticed how oranges are stacked at the store? Grocers know that the most attractive and stable arrangement is a pyramid. Johannes Kepler suspected this pyramid-stacking was superior, way back in the 17th century. But the German scientist also noted that he couldn’t prove it. Sadly, like Kepler, many mathematicians may never live to…
From the rumble of boats to the din of oil drilling, sounds from human activity cascade across the oceans. This noise can bother ocean creatures. And climate change may make some spots even louder. Researchers have expected the oceans to get noisier because of increasing human activity. “The more goods you buy, the more shipping…
Except for a handful of manned missions to the moon, people have seen celestial bodies only from afar. But sometimes, bits of those far-off space rocks crash onto Earth. We call these rogue bits of space rubble meteorites. And they offer rare, handheld samples of the materials that make up distant places in the solar…
Solar cycle (noun, “SOHL-err SY-kuhl”) The solar cycle is a roughly 11-year cycle in the sun’s activity. At the start of each cycle, the sun’s activity is low. It’s at a so-called “solar minimum.” Over an average four years, the sun’s activity rises to a “solar maximum.” Over another seven years or so, it quiets…
