Scientists have found the code for a powerful antibiotic within the giant panda genome, according to a story in the Telegraph. Pandas' immune systems naturally produce the small anti-bacterial protein, but their critically low numbers and almost invariable failure to breed in captivity rule the animals out as a potential source for the compound.
As bacteria continue to grow more resistant to a wide range of antibiotics, doctors are searching furiously for better ways to kill infectious microbes. Enter hydroxyurea. Researchers at MIT and Boston University have discovered that hydroxyurea, normally a drug prescribed for sickle-cell anemia or psoriasis, also causes bacteria to create their own poisons and kill themselves.
