St. Jude study shows genes play an unexpected role in their own activation

... genes; those genes became activated even when KIX was disabled in CBP/p300. Further studies suggested that this KIX-independent mechanism can act on the same gene as the KIX-dependent mechanism; and that each mechanism may or may not contribute equally to activating a specific gene. The team also found ...

Understanding why C. difficile causes disease -- it's hungry

...he United States and Canada. Recently, this strain was shown to be responsible for more than half of all cases in a representative sampling in Quebec. The highly virulent strain has a much higher toxin production which leads to more destructive and deadly disease, says Vivian Loo of McGill University. ...

Definitive evidence found of a swimming dinosaur

...s on the surface of the site indicate the dinosaur was swimming against a current, struggling to maintain a straight path. "The dinosaur swam with alternating movements of the two hind limbs, a pelvic paddle swimming motion," said Costeur. "It is a swimming style of amplified walking with movements si...

'Smart' mice teach scientists about learning process, brain disorders

...nditions, Dr. Bibb said. The key in this study was being able to "knock out" the gene for Cdk5 only in the brain, and only when the mice were adults. This technique, only recently developed and called conditional knockout, allows much more sophisticated experiments than traditional knockout, which en...
