Scientists have been working hard to create artificial gametes, or reproductive cells, from stem cells. This could be a big deal for reproductive medicine. Recently, a team looked into how to turn mouse bone marrow mesenchymal stem cells (mBMMSCs) into late-stage germ-like cells (GLCs). They wanted
Plastics are everywhere. They are in our water, our food, and even inside our bodies. But how do they get from a mother to her unborn child? Scientists used rats to find out. They fed the rats tiny plastic particles, smaller than a speck of dust. These particles were tagged with a special marker so
Gasoline spills are a big problem. They can pollute the air and even cause explosions. This is because gasoline evaporates quickly, releasing harmful chemicals. But predicting how fast this happens is tricky. Different places, like cities or countryside, have different conditions. Wind, temperature,
Lactate levels in horses can tell us a lot about their endurance and training needs. Scientists have found ways to predict how much lactate a horse can handle during exercise without getting too tired. This is called the maximal lactate steady state (MLSS). To figure this out, researchers put ten te
Athletes often wonder how to pace themselves in long-distance races. This is not just about running fast. It is about managing energy to finish strong. Different athletes use different strategies. Some start fast, others slow, and some keep a steady pace. But what works best? This is not clear. Stud
A Soyuz rocket lifted off on Thursday, carrying three astronauts to the International Space Station (ISS). The crew, including two Russian cosmonauts and one NASA astronaut, reached the ISS safely. But back on Earth, a big issue popped up. A huge 20-ton service platform wasn't secured properly befo
Vermivora warblers, small songbirds, face a big challenge during migration: crossing the Gulf of Mexico. This journey is risky, with many birds not making it. To understand why and how they attempt this flight, researchers tracked 89 warblers from 2013 to 2017 using tiny devices that record light le
The human gut is home to trillions of bacteria. These tiny organisms play a big role in keeping us healthy. They can also be linked to diseases like inflammatory bowel disease (IBD). Scientists have been studying these bacteria using different methods. One method is metagenomics. It helps identify b
In the world of medical imaging, scientists are always looking for ways to make brain scans clearer. One recent approach involves using sodium signals to improve phosphorus scans. This might sound a bit odd, but it's all about making the most of the data we have. Phosphorus scans, or 31 P MRSI,
In the vast Atlantic Ocean, tiny bacteria and viruses are always interacting. These bacteria can be divided into two groups: those with a lot of genetic material (HNA) and those with less (LNA). This difference matters because it affects how viruses attack them. Scientists studied these interaction
