The implantation of medical devices is not without risks. Bacterial or fungal infections can occur and the body's strong immune response may lead to the rejection of the implant. Researchers have succeeded in creating a biofilm with antimicrobial, antifungal and anti-inflammatory properties.
Scientists have developed a method for synthesising organic molecules very selectively, by assembling simple molecules and using an enzyme from E. coli , which acts as a biocatalyst. This is a significant step forward since it replicates the formation of carbohydrates in conditions resembling those that presumably initiated life on the Earth and because it allows relatively large organic molecules to be obtained very selectively and efficiently.
Researchers have built a molecular Swiss Army knife that streamlines the molecular machinery of cyanobacteria, also known as blue-green algae, making biofuels and other green chemical production from these organisms more viable.
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.
