A team of scientists from the Garvan Institute of Medical Research and the Universities of New South Wales and Sydney has identified a new DNA structure — called the intercalated motif (i-motif) — inside living human cells.
Researchers in several disciplines need to tread carefully over shared landscapes of the past.
Burials from a cave in Morocco have yielded the oldest human DNA evidence yet from Africa, offering new insight into Stone Age migrations.
Ending a long-standing mystery that once set the unidentified flying object community abuzz, researchers have sequenced the entire genome of a strange, 15-centimeter-tall human skeleton and identified mutations that may be responsible for its odd appearance.
Russian researchers have analyzed tissue samples from one of the mysterious alien creatures uncovered in Peru last year. The mummy, with an elongated skull and only three fingers, has excited ufologists since its discovery.
Ancient DNA from this skeleton, found in a Moroccan cave, is the oldest known from Africa.
In a handful of medieval Bavarian farming hamlets populated mostly by blue-eyed blondes, more than a dozen women with dark hair, dark eyes, and unusual elongated skulls would have stood out.
Space travel is dangerous for a lot of very obvious reasons — traveling off of Earth on a rocket has its risks, after all — but even when everything goes well it seems that a brief stay in space has the potential to alter a person’s very DNA.
Discovering something for the second time might sound like a letdown. Not for ecologists in Hawaii, who have found that spider-eating spiders on four islands there independently evolved the same colors: gold, black, and white. This rare example of parallel evolution, which has also been seen in one other Hawaiian spider, could help clarify one of biology’s biggest mysteries: how and when evolution repeats itself.
The Human Genome Project was completed in 2003 and was set up in order to discover more about our “human blueprint”,where some scientists believe human DNA did not originate on this planet.
