During the last 4 billion years, ancient enzymes have adapted from a much hotter, more acidic environment to the cooler global one that exists today.
The enzymes, known as thioredoxin were chemically stable at temperatures up to 32 degrees Celsius (58 degrees Fahrenheit) higher than their moder... Read More
For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.
Developing this nanofiber sphere as... Read More
