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 levels. Weather plays a big role in when these birds decide to cross t...
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 bacteria and their connection to health or disease. But there's a catc...
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, are useful but can be a bit fuzzy. This is because the signal-to-nois...
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 interactions during spring in the Northeast Atlantic. They found that the ocean'...
In a surprising discovery, scientists have found evidence of small lightning strikes on Mars. These tiny sparks were picked up by the microphone on NASA's Perseverance rover. The sounds were recorded during dust storms and dust devils, with 55 instances documented over two Martian years. These electrical discharges are similar to static electricity on Earth and were ...
Heart scans using MRI give doctors a clear look at the heart's structure. This helps in spotting heart problems early. But, making these scans work well with computers needs lots of labeled data. Labeling data is a big job. It takes time and effort. A new method called PDFMSeg changes this. It uses a small amount of labeled data and a lot of unlabeled data. This mak...
A team of space explorers has just begun their journey to the International Space Station (ISS). This mission involves a mix of seasoned and new astronauts. The Soyuz MS-28 spacecraft, powered by a Soyuz 2. 1a rocket, took off from the Baikonur Cosmodrome in Kazakhstan. The launch happened at 12:28 pm Moscow time, which is 0928 GMT. The crew consists of two Russians...
Dark matter has been a big question in science for a long time. It's like an invisible glue holding galaxies together. Now, a scientist thinks they might have found some proof of it. The idea of dark matter started way back in the 1930s. A scientist named Fritz Zwicky noticed that galaxies were spinning too fast. He figured there must be something invisible out ther...
Ever wonder how your brain deals with weird or unexpected info? Well, it turns out your brain has a cool way of sorting things out. Scientists used EEGs to peek inside the brain and see what happens when we process odd data. They found that our brains use two main modes: automatic and controlled processing. In the automatic mode, the brain's frontal-parietal regions...
Ever thought about how your brain changes and grows? It turns out that tiny cells in your blood, called platelets, might play a big role in this. These little guys are like messengers, carrying important signals from your body to your brain. They help your brain adapt and change, a process known as brain plasticity. Platelets are usually known for their role in clot...
