Researchers unmask malaria parasite's cloaking mechanism

... tight packaging involves SIR2," said Cowman. "The question then was how one of those genes is switched back on." The researchers knew that, in some organisms, gene regulation is dictated not only by DNA sequence and the way that sequence is folded, but also by physical location. In these cases, the expressio...

"He's definitively answered a question that had been debated for years by creating a brilliant microscopy system, giving life sciences researchers the ability to watch specific cells over time in a user-friendly, high-throughput way. The extraordinary thing about Steve -- something for wh...

Unchecked DNA replication drives earliest steps toward cancer

...earchers at The Wistar Institute answer this vital question and suggest why mutations in a certain few genes, such as the p53 tumor suppressor gene, are found in so many different cancers. Mutations in p53 are found in the majority of human cancers, for example. The Wistar team's primary observation is that a...
