health: Study Says Motion Sickness Is in the Genes


Study Says Motion Sickness Is in the Genes

If you feel an unpleasant queasiness while traveling in a car or boat, it could be genetic, according to a recent study by personal genomics company 23andMe. Using genetic data from more than 80,000 of its customers, 23andMe was able to link motion sickness to 35 genetic factors—many of which are involved in the nervous system, balance, and eye and ear development. However, having these gene variants does not guarantee that one will experience motion sickness. Research also showed that those who suffer from motion sickness are more likely to develop vertigo and migraines. More… Discuss

DNA analysis is an invaluable forensic tool, but it has its limitations. Until now, crimes and paternity cases involving monozygotic—”identical”—twins could not be resolved using DNA, since the genetic makeup of such twins is virtually indistinguishable given current analysis methods. Even though there are minute differences between the genetic codes of identical twins, time constraints and prohibitive costs have kept tests to detect them out of reach of law enforcement. However, a relatively quick and affordable new DNA test could be the answer investigators have been looking for. More… Discuss
