...groundbreaking feat of computation, a team of international scientists—including Harvard researchers—have calculated the precise energy of a hydrogen molecule using a quantum computer...
While scientists have been able to determine the energy of hydrogen using paper and pencil since the 1930s, they now know they can use a quantum computer to perform this—and hopefully more complex calculations—with precision. Using classical computers, calculating the energies of larger molecules was virtually unimaginable because “the numbers get literally astronomical,” according to University of Queensland Physics Professor Andrew G. White, one of the authors of the study published in “Nature Chemistry?...
...fairly simple. Darwin taught us that it takes many generations for a genome to evolve, but researchers have found that it takes only the addition of a methyl group to change an epigenome. A methyl group is a basic unit in organic chemistry: one carbon atom attached to three hydrogen atoms. When a methyl group attaches to a specific spot on a gene - a process called DNA methylation - it can change the gene's expression, turning it off or on, dampening it or making it louder.

...Italy capable of delivering a thermonuclear strike? Could the Belgians and the Dutch drop hydrogen bombs on enemy targets? And what about Germany - a country where fear of atomkraft is so great that the last government opposed all civilian nuclear power? Germany's air force couldn't possibly be training to deliver bombs 13 times more powerful than the one that destroyed Hiroshima, could...
