New additive process can make better -- and greener -- high-value chemicals
Researchers have achieved a significant breakthrough that could lead to better -- and greener -- agricultural chemicals and everyday products. Using a process that combines natural enzymes and light, the team developed an eco-friendly way to precisely mix fluorine, an important additive, into chemicals called olefins -- hydrocarbons used in a vast array of products, from detergents to fuels to medicines. This groundbreaking method offers an efficient new strategy for creating high-value chemicals with potential applications in agrochemicals, pharmaceuticals, renewable fuels, and more.

'Dancing molecules' heal cartilage damage
New therapy uses synthetic nanofibers to mimic the natural signaling of a protein that is crucial for cartilage formation and maintenance. Researchers found that intensifying the motion of molecules within the nanofibers led to more components needed for regeneration. After just four hours, the treatment activated the gene expression necessary to generate cartilage. Therapy could be used to treat osteoarthritis, which affects nearly 530 million people worldwide.

Climate is most important factor in where mammals choose to live, study finds
Using data from 6,645 camera traps across the United States, researchers mapped populations of 25 mammal species. They determined that climate, not human activity, was the primary factor in mammals deciding where to live.
