Study proposes smart sutures with sensors for wounds

(Phys.org)—What if sutures could be coated with sensors to monitor wounds and speed healing? A recent study published in the journal Small indicates materials and methods that show it may be part of the medical science ...

Study shows how DNA finds its match

It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions of 'letters' ...

DNA repair protein caught in act of molecular theft

Scientists have observed, for the first time, an intermediate stage in the chemical process that repairs DNA methylation damage and regulates many important biological functions that impact health conditions such as obesity, ...

DNA and the 'magic rings' trick

(PhysOrg.com) -- A new study from UC Davis shows how, like a conjuring trick with interlocking rings, two interlocked pieces of DNA are separated after DNA is copied or repaired. The finding was published online Oct. 10 in ...

Key protein aids in DNA repair

Scientists have shown in multiple contexts that DNA damage over our lifetimes is a key mechanism behind the development of cancer and other age-related diseases. Not everyone gets these diseases, because the body has multiple ...

Researchers discover RNA repair system in bacteria

In new papers appearing this month in Science and the Proceedings of the National Academy of Sciences, University of Illinois biochemistry professor Raven H. Huang and his colleagues describe the first RNA repair system to ...

'Sloppier copier' surprisingly efficient

The "sloppier copier" discovered by USC biologists is also the best sixth man in the DNA repair game, an article in the journal Nature shows.

Human DNA repair process recorded in action (Video)

(PhysOrg.com) -- A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis. The recordings provide new information about ...

New biomaterials can be fine-tuned for medical applications

Researchers in the UK and the United States have succeeded in 'fine tuning' a new thermoplastic biomaterial to enable both the rate at which it degrades in the body and its mechanical properties to be controlled independently.
