Bacterial Toxin Surprises Scientists
... walls are not made exclusively of protein, but contain parts of the membrane. Despite their efforts, the researchers also remain baffled by exactly which parts of the protein are responsible for triggering channel opening and closing. As with much scientific di...Key to Triplet Repeat Brain Diseases Open Door For New Way To Understand, Treat Genetic Diseases"
...iplet repeat diseases wouldnot apply to those that contain stuttering sequences in the "junk"area of the genome, since those areas do not encode for protein production.The genetic disease called myotonic dystrophy is an example of such a disorder. The interdisciplinary research under Roses was a key to the ....... Newly emerged adult Neopyrochroa beetles do not contain cantharidin. But by the time adult beetles are caught in the field and subjected to mass spectrometry, they test positive for Spanish fly.

Ocean sediments contain a record of past vegetation fires, called biomass burning by scientists -- and this record shows much more past burning, at least in Africa during the Pleistocene era, than researchers expected.
