Downhill running is tough on muscles. It causes more damage and soreness than regular running. This is because it involves eccentric exercise, where muscles lengthen under tension. Scientists wanted to see how this affects the tiny powerhouses in muscle cells, called mitochondria. They used rats for
The world is facing big problems with climate change, global warming, and not enough water. These issues make droughts worse and threaten the food we grow. Scientists are looking for new ways to help plants survive these tough conditions. One promising solution comes from Moringa, a plant known for
Minamiiwoto Island, part of the Ogasawara Islands in subtropical Japan, is a unique place. It has never been messed up by humans or invaded by foreign animals. This makes it a perfect example of how oceanic islands should work. Seabirds and land crabs play a big role in keeping the island's ecosyste
Nuclear energy is a big deal for the United States. It's not just about keeping the lights on, but also about national security and the economy. For a long time, the U. S. has been a leader in nuclear power. From 1954 to 1978, 133 civilian nuclear reactors were built at 81 power plants. But since 19
Brain blockages are a big deal. They are a major cause of strokes around the globe. Doctors are still figuring out the best ways to handle these blockages. A recent gathering of experts shared their thoughts on how to manage these issues. They all agreed that changing lifestyles and using medicines
The Trump administration is in a heated debate with a government watchdog over funds meant for electric vehicle charging stations. The Government Accountability Office (GAO) released a report claiming that the Trump administration is breaking the law by not spending money as directed by Congress. Th
Ever thought of seeing in the dark? Scientists have created contact lenses that let humans and mice see near-infrared light. This light is usually invisible to us, but these lenses convert it into visible colors. The secret? Special nanoparticles embedded in the lenses. These nanoparticles absorb in
Hawaii's Big Island has two unique beaches: Papakolea and Richardson Ocean Park. They are quite different. Papakolea is exposed to the open ocean and has fine sand. Richardson is sheltered and has coarse sand. This makes them perfect for studying how microbes live in different coastal environmen
Water and plastic do not mix well. This is especially true for tiny plastic bits called microplastics. These tiny plastics float around in our oceans and rivers. The way they move and settle depends on many things. Their shape, how round they are, and even how they interact with water. When these pl
Lichens are tough and can handle harsh conditions. They make melanin, a pigment that helps them survive in tough spots. This pigment is like a shield, protecting them from too much light and UV rays. One type of lichen, Lobaria pulmonaria, has been studied for its melanin. It turns out, this lichen
