Future Mars explorers face a big challenge: no grocery stores on the red planet. They can't rely on Earth for fresh supplies either, as resupply missions are too far away. So, how will they get enough food? A new project might have the answer. The European Space Agency (ESA) and Solar Foods are wor
Freezing stuff without damaging it is a big deal. Think about ice cream. If it melts and refreezes, it gets all grainy. Now imagine that happening to cells or even organs. Not good, right? Scientists have been working on ways to freeze and thaw things without causing damage. They've come up with som
In a move that has sparked widespread criticism, Tunisian authorities have arrested a key opposition figure, Chaima Issa, as part of a larger crackdown on dissent. Issa was taken into custody during a protest in Tunis, where she was set to serve a 20-year prison sentence. This arrest follows a court
Proteins are like tiny workers in our body, and they often need a bit of a tweak to do their jobs right. One such tweak is called SUMOylation. It's like adding a small tag to a protein, which can change how it works, where it hangs out in the cell, or even how long it sticks around. This tagging pr
Scientists have created a smart material that can detect and remove harmful antibiotic residues from food. This material, called ZIF-8@ZIF-8, is like a tiny sponge with special glowing properties. It can sense and soak up tetracyclines, a type of antibiotic often found in animal products. The mater
Proteins are like tiny machines in our bodies, and knowing their shapes can help us understand how they work. For a long time, figuring out these shapes was a big challenge. Scientists had to spend lots of time and money on experiments to get even a few answers. But then, AlphaFold came along and ch
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
A former Peruvian president, known for his humble beginnings, has been given a significant prison term. Pedro Castillo, once called the \"president of the poor, \" was sentenced to over 11 years in prison. This was for his attempt to shut down Congress and rule without their approval. Castillo, a f
Japan's top bond dealers are pushing for a change in the government's bond sales strategy. They want more short-term notes, like two-, five-, and ten-year bonds. At the same time, they're asking for fewer super-long bonds to be issued. This shift comes as Japan's longer-term bonds have been under p
For years, people have been changing the land around ancient sites. This change can hurt these important places. A recent study looked at how to use satellites to track these changes. The focus was on Amrit, an old archaeological site in Syria. The study used different types of satellite images. Th
