Elliptical galaxies hold a fascinating secret in their ultraviolet (UV) light. This secret could help scientists figure out how old these galaxies are. Recent studies have shown that the UV light from these galaxies comes from different types of stars. Some are metal-poor, and others are metal-rich
Bioarchaeology deals with bones from the past. But these bones don't tell the whole story. There are hidden factors that affect what we find. Computers can help us understand these hidden things better. Computers use math to make models. These models can show how hidden factors change what we see i
Imagine a world where robots handle the boring tasks in space. That is what Ethan Barajas and Jamie Palmer are aiming for. Their company, Icarus Robotics, is creating robots to take over routine jobs on the International Space Station. This way, astronauts can focus on important research. The space
In the early hours of November 25, atop Hawaii's Maunakea volcano, scientists eagerly watched as the interstellar comet 3I/ATLAS made its way out of our solar system. This comet, a small, blurry speck among countless stars, was more than just a celestial object—it was a time capsule, older than our
Skipjack tuna are fascinating creatures that roam the oceans. Scientists wanted to understand more about their movements, especially during spawning and winter. They focused on the northern coast of Japan, where these tuna live. Using special tags, researchers tracked the tuna. They found two group
Mars, the dry and dusty planet we know today, might have once been a much wetter place. Recent findings from NASA's Perseverance rover suggest that tropical storms could have soaked the Red Planet for millions of years. The rover found light-colored rocks scattered around its path. These rocks, made
A comet named 3I/ATLAS is on a long trip through our solar system. It's not from around here. It came from another star system. This is only the third time scientists have seen something like this. Some people wonder if it could be from aliens. An astronomer named John Tonry works with a system tha
Xenotransplantation, or the process of transplanting organs from animals to humans, has made significant progress. Scientists are now planning clinical trials, but there's a big question: will people be okay with it? Understanding what people think about this is crucial. Without public support, the
One hundred years ago, a groundbreaking experiment shook the world of biology. It was not flashy or loud, but it changed how scientists think about how living things grow and develop. This experiment, done by Hans Spemann and Hilde Mangold, showed that some cells in an embryo have special powers. Th
Plants have a clever way to fight off viruses. They use a system called SAR, which stands for systemic acquired resistance. SAR acts like a plant's immune system, helping it remember past infections and protect itself better in the future. Salicylic acid (SA) and its friends, like MeSA and AzA, are
