...ene's protein product is involved in the repair of broken DNA, therefore explaining the children's illness: the generation of the vast repertoire of immune cells (B and T cells) that protect us against pathogens involves the breakage and rejoining of DNA. Exposure to radiation also results in DNA breaks tha...High sugar blood levels linked to poor memory

The new study attempted to extend the observations about cognitive impairment in diabetics to otherwise healthy, non-diabetic aging men and women, some of whom may have impaired glucose tolerance. In the study, the NYU re...Digital X-ray microtomography yields stunning views of limb regeneration
...directly related to wound healing and repairing of broken bones in the clinic," Simon said. "Regenerating newt cells are similar to activated stem cells.

...possibilities of embryonic stem cells in repairing broken hearts, but stem cell technology offers even more -- and it offers it much earlier," said Dr. Lior Gepstein of the Technion Faculty of Medicine who headed the study. "Currently, we test drugs on animals, but we would get more reliable results if we t...Facing extreme ice conditions, coast guard, NSF deploy second icebreaker to Antarctica
...o keep it open. Although the Polar Sea already has broken a channel into the McMurdo Sound as far south as Hut Point, the ice conditions are so severe that one ship, in the time available, might not be able to prepare the channel and escort the re-supply ships through the heavy pack ice without the assistan...Radiation-resistant organism reveals its defense strategies
...nized in a unique ring that prevents pieces of DNA broken by radiation from floating off into the cell's liquids. Unlike other organisms, in which DNA fragments are lost due to radiation, this microbe does not lose genetic information because it keeps the severed DNA fragments tightly locked in the ring b...Zebrafish may point the way to mending a broken heart
...esearchers have found that the secret to mending a broken heart at least at the molecular level resides within the two-chambered heart of a fish commonly found in household aquariums. The scientists showed that the zebrafish can regenerate its heart after injury, and their studies suggest that understandi...New CU-NASA research belies previous idea that Mars was once warm, wet planet
...on a cold and dry planet, an almost endless winter broken by episodes of scalding rains followed by flash floods. "Only during the brief years or decades after the impact events would Mars have been temperate, and only then might it have bloomed with life as we know it," they wrote. Although temperatures i...Structure of pain-modulating enzyme described by scientists at the Scripps Research Institute
... their activity are regulated by how fast they are broken down." In particular, the body releases an endogenous cannabinoid called anandamide, a name derived from the Sanskrit word meaning "internal bliss." When the body senses pain, anandamide binds to CB-1 and nullifies pain by blocking the signaling. How...$3.2 million project to document dioxin levels in Houston ship channel
...al processes also can create dioxins. Dioxins are broken down in the environment very slowly, and can be deposited on plants and taken up by animals and aquatic organisms.

For a long-term cure, the gene has to wedge itself into a chromosome where it remains indefinitely integrated, getting passed on when the cell divides.
