Medicine is the branch of health science and the sector of public life concerned with maintaining or restoring human health through the study, diagnosis and treatment of disease and injury. It is both an area of knowledge – a science of body systems, their diseases and treatment – and the applied practice of that knowledge.

Overview


Medical care is shared between the medical profession (physicians or doctors) and other professionals such as nurses and pharmacists, sometimes known as allied health professionals. Historically, only those with a medical doctorate have been considered to practice medicine. Clinicians (licensed professionals who deal with patients) can be physicians, nurses, therapists or others. The medical profession is the social and occupational structure of the group of people formally trained and authorized to apply medical knowledge. Many countries and legal jurisdictions have legal limitations on who may practice medicine.

Roadside assistance for Mars rover
Fri, 03 Jul 2009 00:00:00 -0700
The Spirit rover is stuck in the Red Planet's fluffy soil, so engineers at JPL have re-created the scene in a sandbox to figure out how to get it free.

El Nino more like Los Ninos, weather study finds

Sheep getting smaller in Scotland due to climate change, study says
Fri, 03 Jul 2009 00:00:00 -0700
The average weight and size of sheep on a remote island have been falling in small but steady increments since 1985. Milder winters mean smaller animals but a larger herd. Along with polar icecaps and sandy beaches, sheep on a remote Scottish island are gradually shrinking as a result of global warming, according to a study published today in the journal Science. The finding offers unusual proof that large animals are already evolving to adapt to changes wrought by climate change, experts said.
