Over 1,000 aspirants, including 62 from India, have been shortlisted for an ambitious private mission to send four men and women on a one-way trip to Mars in 2024 to establish a More »
The arms race is between mobile DNA sequences known as “retrotransposons” (a.k.a. “jumping genes”) and the genes that have evolved to control them. The UC Santa Cruz researchers have, for the first time, identified genes in humans that make repressor proteins to shut down specific jumping genes. The researchers also traced the rapid evolution of the repressor genes in the primate lineage.
Their findings, published September 28 in Nature, show that over evolutionary time, primate genomes have undergone repeated episodes in which mutations in jumping genes allowed them to escape repression, which drove the evolution of new repressor genes, and so on. Furthermore, their findings suggest that repressor genes that originally
A new study led by senior research scientist Sid Kouider and PhD student Thomas Andrillon at the Ecole Normale Supérieure de Paris in France has investigated how active our brains a
At the moment, when our livers fail the only option is to perform a partial or complete transplant. Not only this costly and inherently risky, it’s also not always possible – there are far more patients needing liver transplants than donors.
But now South Korean scientists have discovered a new technique that could allow doctors to inject stem cells from the tonsils into the liver to repair damage – all without surgery.
Scientists have already started taking
