DNA May ID Sailors Looking for Northwest Passage in 1845

Scientists have extracted DNA from the skeletal remains of several 19th-century sailors who died during the ill-fated Franklin Expedition, whose goal was to navigate the fabled Northwest Passage. With a new genetic database of 24 expedition members, researchers hope they’ll be able to identify some of the bodies scattered in the Canadian Arctic, 170 years…

Beyond the DNA

Scientists have established comprehensive maps of the human epigenome, shedding light on how the body regulates which genes are active in which cells. Over the last five years, a worldwide consortium of scientists has established epigenetic maps of 2,100 cell types. Within this coordinated effort, the CeMM Research Center for Molecular Medicine contributed detailed DNA…

X-Files DNA mystery unlocked

Scientists have unlocked a crucial part of the mystery as to how our DNA can replicate and repair itself – something which is essential for all life forms. The new research, conducted by leading scientists at the University of Sheffield, has revealed how branched DNA molecules are removed from the iconic double-helical structure -a process…
