Mysterious gas clouds near Milky Way's black hole now have a likely source

For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But new research from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) suggests that this limitation may not be permanent. Instead, the capacity for regeneration may still exist—hidden within the body's normal healing process.

Most of the carbon fixed by plants through photosynthesis is ultimately stored in the cell wall, primarily in the form of polysaccharides such as cellulose, xylan, and glucomannan. Yet how plants efficiently synthesize these wall polymers has remained unclear, particularly because polysaccharides such as glucomannan and xylan are prone to aggregation through hydrogen bonding and hydrophobic interactions.
