Researchers have developed a user-friendly technology to help scientists understand how proteins work and fix them when they are broken. Such knowledge could pave the way for new drugs for a myriad of diseases, including cancer.
Scientists have identified a new component of the molecular machinery a cell uses to repair damaged DNA. The discovery adds important knowledge about a fundamental life process that protects from diseases such as cancer.
Advances in 3-D printing have led to new ways to make bone and some other relatively simple body parts that can be implanted in patients. But finding an ideal bio-ink has stalled progress toward printing more complex tissues with versatile functions. Now scientists have developed a silk-based ink that could open up new possibilities toward that goal.
Researchers have developed a technique to build tiny models of human tissues, called organoids, more precisely than ever before using a process that turns human cells into a biological equivalent of LEGO bricks.
The motion of micro-organisms as they swim through various types of fluid channels show 'quite strange and new' responses for single cell organisms, including the performance of somersaults, meandering wanderings, and even a ballistic type of behavior.
