[:es] Researchers link three people on a brain-to-brain network.[:]

[:es]The idea that chemical tags on genes can affect their expression without altering the DNA sequence, once surprising, is the stuff of textbooks. The phenomenon, epigenetics, has now come to messenger RNA (mRNA), the molecule that carries genetic information from DNA to a cell’s proteinmaking factories. At a conference here last month, researchers discussed evidence…

[:es]The perpetual shortage of human organs for transplant has researchers turning to farm animals. Several biotech companies are genetically engineering pigs to make their organs more compatible with the human body. But some scientists are pursuing a different solution: growing fully human organs in pigs, sheep, or other animals, which could then be harvested for…

[:es] Research finds a fundamental link between enforcement and the suppression of selfish behaviour. [:]

[:es]In what may be a cautionary tale for citizen scientists trying to save North America’s iconic monarch butterfly, new research has found that butterflies raised in captivity are sometimes unable to migrate—some as a result of missing genes and others for want of the right environmental cues.[:]
