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
Researchers have been working hard to find a way to control HIV without daily medication. A recent study involving 10 participants showed some promising results. The participants received experimental treatments designed to boost their immune systems. After stopping their usual HIV medication, six o
Zinc-65 is a special kind of zinc that is useful in medicine and industry. Scientists wanted to find the best way to make it. They looked at different methods to see which one works best. They used special computer programs to study how different particles, like protons and alpha particles, interac
Ever wondered how cycling and visual tasks affect your brain? A small study tried to find out. They looked at how cycling on a stationary bike and a visual task, like searching for items, impact brain function. Twenty-seven young adults took part. They did four sessions. First, they checked their f
In the first four months of life, a baby's immune system goes through big changes. This is how it works in Papua New Guinea. Researchers looked at 87 babies. They checked 41 different immune system messengers in the blood. These messengers are called cytokines and chemokines. At birth, the levels o
