Microbes are everywhere, even in freezing places like glaciers. Some of these cold-loving microbes have special proteins called CryoRhodopsins, or CryoRs for short. These proteins are like tiny sensors that help the microbes detect ultraviolet (UV) light. What makes CryoRs unique is a special amino
In the world of smart drug delivery, scientists are always looking for ways to make sure medicines reach exactly where they are needed. One way to do this is by using special molecules called acetals and ketals. These molecules can break down in acidic environments, like those found in tumors or ins
Tuberculosis (TB) and COVID-19 are both nasty lung infections. They can cause a lot of damage to the lungs. Scientists wanted to see what happens when someone has both infections at the same time. They used a special type of lung cell, called A549 cells, to study this. First, they infected the cell
Tiny robots are making big waves in medicine. These little helpers, called microrobots, can move around without wires. They could one day help doctors treat patients without surgery. But there's a problem. Most microrobots are made from soft materials. They can't move well in fast-flowing blood. The
Near a lake in present-day Germany, a group of Neanderthals set up a clever system to get fat from animal bones. They smashed bones with stone tools and boiled them to get the fat. This was not a one-time thing. It happened over 300 years. They did this to avoid a dangerous condition called protein
Life needs RNA and fats. But could life exist with just these two? RNA does more than just carry information; it can also speed up reactions. This idea has led scientists to think about a time when life might have started with just RNA. But RNA needs help to stay organized and work properly. That's
Droughts are becoming more common and severe. This is bad news for watermelons, which need plenty of water to grow. Farmers are struggling to keep their crops healthy and productive in these harsh conditions. Scientists are looking for ways to help. One promising solution is a gene called ClTCP4. T
Scientists have found a clever way to spot lead using tiny glass holes. They can't see lead directly, so they use a special trick. Here's how it works: they mix lead with some smart DNA bits. These bits react and create a signal. This signal is big enough for the glass holes to notice. The cool par
Digging up old bones and teeth might not sound exciting, but they hold secrets about our past. These secrets are hidden in tiny clues called isotopes. Isotopes are like fingerprints that tell us about the food people ate, the water they drank, and even the air they breathed. Scientists study these
Scientists have created new glowing materials that could make our screens and lights more efficient. These materials are made by mixing tiny amounts of two special substances, anthracene and perylene, into a base material called acenaphthene. When light hits these new materials, they glow in differe
