Biomaterials Get Stem Cells to Commit to a Bony Future

With the help of biomimetic matrices, a research team led by bioengineers at the University of California, San Diego has discovered exactly how calcium phosphate can coax stem cells to become bone-building cells. This work is published in the Proceedings of the National Academy of Sciences the week of Jan. 6, 2014.

Nanosponge Vaccine Fights MRSA Toxins

Nanosponges that soak up a dangerous pore-forming toxin produced by MRSA (methicillin-resistant Staphylococcus aureus) could serve as a safe and effective vaccine against this toxin. This “nanosponge vaccine” enabled the immune systems of mice to block the adverse effects of the alpha-haemolysin toxin from MRSA—both within the bloodstream and on the skin. Nanoengineers from the University of California, San Diego described the safety and efficacy of this nanosponge vaccine in the December 1 issue of Nature Nanotechnology.

New Injectable Hydrogel Encourages Regeneration and Improves Functionality After a Heart Attack

University of California, San Diego bioengineers have demonstrated in a study in pigs that a new injectable hydrogel can repair damage from heart attacks, help the heart grow new tissue and blood vessels, and get the heart moving closer to how a healthy heart should. The results of the study were published Feb. 20 in Science Translational Medicine and clear the way for clinical trials to begin this year in Europe. The gel is injected through a catheter without requiring surgery or general anesthesia—a less invasive procedure for patients.

Electrical Engineers Build “No-Waste” Laser

A team of University of California, San Diego researchers has built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, “thresholdless” laser that funnels all its photons into lasing, without any waste.

Engineers Find Inspiration for New Materials in Piranha-proof Armor

It’s a matchup worthy of a late-night cable movie: put a school of starving piranha and a 300-pound fish together, and who comes out the winner?
