In Cuba, spiritual leaders from the Afro-Cuban religion Santería are stepping up their efforts to promote peace and harmony. With tensions between the United States and Cuba on the rise, these priests and priestesses are turning to their deities for help. They believe that through prayers and offeri
In Cuba, spiritual leaders are turning to ancient traditions to cope with growing concerns. As the country faces economic struggles and political tensions with the United States, priests and priestesses of Santería are holding ceremonies to seek peace and harmony. These ceremonies are not just abou
PET scans are a big deal in medicine. They help doctors see inside the body. But sometimes, the pictures come out blurry. This happens because tiny light particles, called gamma photons, bounce around. They hit different spots than they should. This is called inter-crystal scattering, or ICS for sho
Ever wondered how to make things slide smoothly and quietly? Scientists have been working on this problem for a while. They wanted to create materials that can handle water well and reduce friction and noise. This is important for things like machinery parts that need to move smoothly without making
Colon cancer is a big deal. It's the third most common cancer and the fourth leading cause of cancer deaths worldwide. Most cases start with harmless polyps that turn nasty over time due to genetic changes. But there's more to it than just genes. Inflammatory bowel disease (IBD) can also raise the r
MXene, a special kind of material, has been a hot topic in science. It is known for its amazing abilities. But there is a big problem. It tends to break down in water. This breakdown creates a coating that ruins its performance. This makes it hard to use in real-world applications. Scientists have
AI is stepping up to tackle a big problem in green technology. Scientists have long known that tiny microbes can help create nanomaterials in an eco-friendly way. But with so many microbes and nanomaterials out there, finding the right matches has been like searching for a needle in a haystack. Ent
Zinc metal batteries are seen as a great option for affordable and eco-friendly energy storage. However, they have a big issue: zinc ions struggle to move around efficiently. This is because they stick too much to water molecules, causing uneven growth and other problems. To tackle this, scientists
In the world of tiny tech, scientists are always looking for new ways to control how things work. One big challenge is managing electromagnetic waves, especially those in the terahertz (THz) range. These waves are tricky to control, but a new idea might just change the game. Scientists have found a
In the world of materials science, tiny changes can lead to big surprises. Take EuVO2H films, for example. These films are special because they can handle a mix of europium ions (Eu2+ and Eu3+) without falling apart. Normally, when europium changes its valence, it causes big problems. The ions are d
