In “before” and “after” photos from advertisements for wound-healing ointments, bandages and antibiotic creams, we see an injury transformed from an inflamed red gash to smooth and flawless skin.

What we don’t appreciate is the vital role that our own natural biomolecules play in the healing process, including their contribution to the growth of new cells and the development of new blood vessels that provide nutrients to those cells. (more…)

ANN ARBOR — Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why.

Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms in cold environments—and this genetic program also exists in warm-blooded animals, including humans. (more…)

Researchers Coat Spinal Polymer Implants with Bioactive Film to Improve Bonding with Bone

Researchers from North Carolina State University have for the first time successfully coated polymer implants with a bioactive film. The discovery should improve the success rate of such implants – which are often used in spinal surgeries.

The polymer used in these implants, called PEEK, does not bond well with bone or other tissues in the body. This can result in the implant rubbing against surrounding tissues, which can lead to medical complications and the need for additional surgeries. (more…)

Unchecked Antibiotic Use in Animals May Affect Global Human Health

The increasing production and use of antibiotics, about half of which is used in animal production, is mirrored by the growing number of antibiotic resistance genes, or ARGs, effectively reducing antibiotics’ ability to fend off diseases – in animals and humans.

A study in the current issue of the Proceedings of the National Academy of Sciences shows that China – the world’s largest producer and consumer of antibiotics – and many other countries don’t monitor the powerful medicine’s usage or impact on the environment. (more…)

Scientists create nanoscale vehicle to battle cancer without harming healthy cells

A tiny capsule invented at a UCLA lab could go a long way toward improving cancer treatment.
Devising a method for more precise and less invasive treatment of cancer tumors, a team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells.
