Why We Burn

Researchers say they have discovered a molecular signal that triggers sunburns.

They believe sunburns may be how the body rids itself of damaged skin cells.

When skin cells are exposed to ultraviolet radiation a specific form of RNA is damaged.

This damaged RNA is then released as a signal and prompts neighboring healthy cells to stimulate factors promoting inflammation.

That process is intended to remove sun-damaged cells, which could turn cancerous if not cleared away.

UAMS dental education

UAMS has established a center for dental education.

It will include an oral health clinic and postgraduate programs for dentists in advanced general dentistry and oral surgery.

The oral health clinic will begin accepting patients in early 2012.

Arkansas needs more dental health care - particularly in school-aged children and in low-income populations.

That's according to a 2008 report to the state legislature.

Kids and Pets

A new study finds pets could help keep kids healthier.

Researchers studied nearly 400 children from birth to their first birthday.

They found babies that grew up with cats or dogs had fewer ear infections and respiratory problems.

The authors say animal-interaction helps a baby's immune system to mature.

They also found kids with pets needed less medication even when they were sick.

Still, they say more research is needed on the subject.
