These colonies also gained weight due to sophisticated communication mechanisms like waggle dancing.
Researchers at Penn School Medicine observe and measure internal motion in proteins, revealing its impact on function and overturning traditional views. This discovery may explain why drug design fails more often than it works.
Researchers at the University of Texas M.D. Anderson Cancer Center discovered that a protein called IKK-alpha protects an important cell defense mechanism from silencing in skin cancers. The protein prevents DNA methylation, which normally silences the checkpoint gene 14-3-3-sigma.
