Rubidium is a valuable element found in salt-lake brines, but extracting it has been a tough job. The usual methods aren't great at picking out rubidium from other stuff like sodium, potassium, calcium, and magnesium. But now, there's a new trick: using a special material with lots of sulfonic acid
Non-lethal weapons are meant to control people without killing them. But sometimes, they can still hurt or even kill if used too close. So, a new kind of projectile was made. It's called a frangible projectile. It's small, about 18. 4 mm, and it's made of a special plastic called PMMA. Inside, it ha
In the early 20th century, a big collection of old Irish folk remedies was put together. These remedies were used to treat all sorts of illnesses. The people who used them were mostly from the countryside and were born between 1850 and 1925. Some of these remedies were pretty unusual. They involved
Scientists have been exploring the inner workings of mouse brains, focusing on the visual cortex. These mice lack a specific gene, Fmr1, which is associated with fragile X syndrome in humans. When researchers placed slices of these mouse brains in a special solution, they observed something unusual.
Giraffes, those tall and graceful creatures, have always fascinated scientists. But there's one thing about them that hasn't gotten much attention: their milk. Specifically, what happens to it as they wean their calves. Milk changes as a mother's body prepares to stop producing it. This is true for
Arizona is set to offer a stunning view of the Cold Moon Supermoon on December 4, 2025. This supermoon is the last of three in 2025 and promises to be a spectacular sight. The state's unique environment makes it one of the top places to watch this celestial event. The Cold Moon gets its name from t
Online surveys are a great way to gather information from many people quickly and cheaply. They can reach folks who might not otherwise participate, like those in remote areas or sensitive groups. But, there's a catch. When surveys are open to everyone via a generic link or offer money, dishonest pe
Science is more than just numbers. Yet, many people judge the value of scientific work by a single figure: the impact factor. This number rates journals, but it doesn't tell the whole story. It's like judging a book by its cover. It's time to think critically about what really matters in science. A
Our eyes are amazing. They let us see the world around us. But did you know there's a tiny world inside your eyes? It's full of tiny messengers. These messengers are like little workers. They help your eyes send important messages. In the retina, there are special cells. These cells have ribbon-like
Enzymes called oxidoreductases are like tiny workers in cells. They help with important jobs like making energy and breaking down food. But they have some problems. They can be expensive, not very stable, and don't work well in tough conditions. So, scientists are looking for alternatives. They are
