Abstract Oxidative stress is the major cause of skin aging that includes wrinkles, pigmentation, and weakened wound healing ability. Application of antioxidants in skin care is well accepted as an effective approach to delay the skin aging process. Methylene blue (MB), a traditional mitochondrial-targeting antioxidant, showed a potent ROS scavenging efficacy in cultured human skin […]
Mitochondria trigger cell aging, researchers discover | KurzweilAI
To their surprise, they observed that the aging cells, after losing their mitochondria, showed characteristics similar to younger cells — that is, they became rejuvenated. The levels of inflammatory molecules, oxygen free radicals and expression of genes, which are among the makers of cellular aging, dropped to the level that would be expected in younger […]
A sponge-filled syringe could save you from bleeding out
RevMedx’s sponge-filled syringe, the XSTAT 30, was approved for military use in treating gunshot wounds last year. Now, the FDA says paramedics and other first repsonders can use the device to treat civilian injuries as well. The syringe is filled with tiny sponges that are designed to control severe bleeding from wounds in places a […]

Scientists make an artificial heart out of foam
The key is a new polymer that can be poured into specific shapes, and has pores that let it pump fluids. It’s not only soft and stretchable, but more efficient — you don’t need much energy to get liquids moving.If the discovery leads to real products, the most obvious use is in smarter, safer artificial […]
