When Harvard Medical School professor Gary B. Ruvkun started researching the development of roundworms 20 years ago, he had no idea that the tiny genes of their ribonucleic acid—DNA’s chemical cousin—would map out a new field of biology.
In light of the researchers’ work with miRNAs, Ruvkun, who received a Ph.D in biophysics from Harvard, said that scientists are now shifting their attention to smaller genes that otherwise might not have been studied. Recent research suggests an increasing awareness of the role of these genes, as...
“The most important thing is it sort of revealed a world of regulation that was mediated by smaller genes that we’ve never envisioned before,” Ruvkun said. “It’s sort of a lens through which one can...
Twenty years ago, Ruvkun and Ambros, then fellows working in the laboratory of MIT professor H. Robert Horvitz, began studying the genes that control the development of the Caenorhabditis elegans, a 1 mm-long roundworm that biologists often use as a model organism, from newly-hatched larva to fully-grown...
To what exact degree physical activity can influence the effect of the FTO gene isn't clear yet, but, says Rampersaud, at least we now know that genes - especially the "wrong" genes - don't necessarily spell out destiny when it comes to weight. And that's a useful lesson to...
