Scientists have been working hard to create artificial gametes, or reproductive cells, from stem cells. This could be a big deal for reproductive medicine. Recently, a team looked into how to turn mouse bone marrow mesenchymal stem cells (mBMMSCs) into late-stage germ-like cells (GLCs). They wanted
Scientists have made a big step forward in healing soft tissues. They created a special gel that can be 3D printed. This gel is made from a protein that acts like collagen, a key part of our skin and other soft tissues. The gel is special because it forms under normal conditions. It doesn't need ha
Medical tools can easily get infected by germs and mold. This is a big problem. Scientists have been working on special coatings to stop these infections. But, they often miss the mold part. Now, a new coating is here. It uses two special molecules: sulfobetaine and borneol. Together, they make a st
The world of brain-computer interfaces (BCIs) is buzzing with a new innovation. MXene microneedle electrodes are making waves as a game-changer in the field. These tiny, needle-like structures are designed to penetrate the skin's surface just enough to get a clear signal from the brain. They are
A new method has been developed to create stronger hydrogels for repairing soft tissues. This method uses tiny fibers made of hydroxyapatite, a mineral found in bones, to reinforce a hydrogel made from polyvinyl alcohol and sodium alginate. These fibers are so small that they can fit into the tiny s
Ever wondered how those custom-made teeth aligners are made and if they're safe? A recent study looked into the safety of 3D-printed aligners made from a material called Tera Harz TA-28. These aligners can have different thicknesses, which might affect how long they need to be cured under UV light t
Three-dimensional printing has revolutionized the way we think about creating tissue replacements. What makes this technique so versatile is the ink used to print the tissues. Ideally, this ink should be safe to use in the body, stable, and capable of maintaining its shape, size, and function after
Scientists have been experimenting with a mix of iron and a calcium compound called hydroxyapatite (HA) to create biodegradable materials. They mixed these powders together and then shaped them into composites using a process called powder metallurgy. They found that how long they mixed the powders
