Human genes: how evolution changes our DNA

Share on PinterestThe researchers looked at the evolutions of human genetics. HECTOR RIO/AFP via Getty Images Researchers looked at the evolution of human genetics. They say they discovered that human genes continued to change after the evolutionary split from primate ancestors. They recognize that genetic research is complicated and further studies are needed. New research …

NEJM Study: Genetic Anomaly Hidden Behind Late-Onset Common Cerebellar Ataxia

Researchers from the University of Miami Miller School of Medicine, McGill University and other institutions have found that a well-hidden genetic variation in the FGF14 gene, called DNA tandem repeat expansion, causes a common form of late-onset cerebellar ataxia, a disorder that interferes with coordinated movement. Tandem repeat expansions are only found in 50 conditions, …

Can we hack DNA to produce more food for a hotter, hungrier planet?

Can we hack DNA to produce more food for a hotter, hungrier planet?

by Lisa M. Krieger Credit: Pixabay/CC0 Public domain To feed a warmer, drier planet, Stanford scientists are building a smarter factory. The team genetically reprogrammed plants, nurtured in a lab chamber, to grow long or short, branched or slender roots, traits that alter the ability to gather nutrients or water. Root growth control could one …

Tracing the DNA of Christopher Columbus: two exhumations in Spain aim to determine the explorer's lineage once and for all

Tracing the DNA of Christopher Columbus: two exhumations in Spain aim to determine the explorer’s lineage once and for all

When Christopher Columbus died on May 20, 1506 in Valladolid, Spain, he left a historical legacy and a mystery about his true origins. Conflicting myths have emerged about the legacy of Christopher Columbus. Official theory has long held that the navigator who reached America was Genoese. In 1898, another hypothesis postulated that the explorer was …

DNA Shows A Mother Was Also Her Daughter's Uncle - How Scientists Solved This Medical Mystery

DNA Shows A Mother Was Also Her Daughter’s Uncle – How Scientists Solved This Medical Mystery

How can a paternity test suggest that a mother is also the father of her daughter? The answer to this medical mystery, sparked by a puzzling paternity test result, is “When the genes of a missing twin brother live in the mother’s DNA.” The finding, which genetics experts reported earlier this month, suggests such human …
