Scientists may have discovered the fifth force of nature, reports the laboratory

It has long been recognized that there are four "fundamental forces" that govern nature. The substance of our universe is contracted or pushed apart by these forces, which are determined by the fact that they do not appear to be reducible to more fundamental interactions between particles. They include gravitational and electromagnetic forces, which produce significant long-range interactions whose effects …

Scientists are just beginning to understand mysterious DNA circles that are common in cancer cells

There is no image in biology that is more iconic than our chromosomes – all 23 pairs of DNA bundles set in a genetic assortment. But in a surprising number of cases, this picture leaves out something very important. In some cells, extra circles of DNA flow along the usual chromosomes. Researchers first noticed this so-called extrachromosomal DNA five decades …
