Cambridge University Scientists Find Quadruple Helix DNA In Human Cells 67

SternisheFan notes that scientists at Cambridge University have found four-stranded DNA in human cells for the first time. "If you've ever studied genetics in school or college, you'll know that the structure of DNA is a double helix. You likely know that DNA carries all of our genetic code. While traditionally we think of only double helix DNA, scientists from Cambridge University in England have made an interesting discovery. According to the researchers, a quadruple helix is also present in some cells and is believed to relate to cancer in some ways. According to the researchers, controlling these quadruple helix structures could provide new ways to fight cancer. The scientists believe the quadruple helix may form when the cell has a certain genotype or operates in a certain dysfunctional state. Scientists have been able to produce quadruple helix material in test tubes for years. The material produced is called the G-quadruplex. The G refers to guanine, which is one of the base pairs that hold DNA together. The new research performed at the University is believed to be the first to firmly pinpoint quadruple helix in human cells."

The LHC, the Higgs Boson, and Fate 691

Reader Maximum Prophet sends a piece from the NY Times by the usually reliable Dennis Overbye reporting on a "crazy" theory being worked up by a pair of "otherwise distinguished physicists": that the Large Hadron Collider's difficulties may be due to the universe's reluctance to produce a Higgs boson. Maximum Prophet adds, "This happened to the Superconducting Super Collider in the science fiction story Einstein's Bridge. Now Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, are theorizing that it's happening in real life." "I'm talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather."
