The often feared and sometimes deadly infections caused by MRSA – methicillin-resistant Staphylococcus aureus – are now moving out of hospitals and emerging as an even more virulent strain in community settings and on athletic teams, and raising new concerns about antibiotic resistance.
Researchers at UT Southwestern Medical Center have found that a molecule produced naturally by muscles in response to nerve damage can reduce symptoms and prolong life in a mouse model of amyotrophic lateral sclerosis (ALS).
MIT and Boston University researchers have discovered that the drug hydroxyurea kills bacteria by inducing them to produce molecules toxic to themselves — a conclusion that raises the possibility of finding new antibiotics that use similar mechanisms.
For more than 400 years, scientists have studied the amazing regenerative power of salamanders, trying to understand how these creatures routinely repair injuries that would usually leave humans and other mammals paralyzed -- or worse.
Radon is a colorless and odorless radioactive gas that is produced by the radioactive decay of radium. Radium is a product of uranium decay and is found in trace amounts naturally in nearly all rocks, soils, and groundwater as well as building materials, plants, animals, and the human body.
