...researchers focused on studying the biology of mitochondria, the powerhouses of the cell where the biochemical processes of energy production occur. Human cells have the ability to switch between mitochondrial respiration and glycolysis, and do so many times throughout the day to match the body’s energy needs with its activities...
...British prisons ban inmates from accessing the Internet except for educational purposes, and then only under staff supervision. But prisoners are still finding ways to update their Facebook pages from behind bars, sometimes using smart phones they've smuggled into jail. More than 3,800 illicit cell phones were seized in British prisons in 2008, prompting authorities to start using mobile-phone signal blockers and body-orifice security scanners in some jails. Nevertheless, officials admit there's not much they can do to stop prisoners from having friends or family update their Facebook pages for them...
...fields while dogs couple in dusty streets. Fauna make their appearance throughout Ko's work - he jabbers lovingly with crabs and cuttlefish and applauds croaking frogs and other critters. "Accept my respects, uncle boars," he offers in one poem. In another, he consoles an insect who shares his sunless cell at Seoul Prison: "I'm awake so I'm your comrade." (See pictures of Seoul...
...field of biological aging has in recent years focused on the long molecules of DNA contained in human cells called chromosomes. All chromosomes have protective caps at either end called telomeres. Each time a cell replicates itself (as it does before it dies), the telomeres shorten, like plastic tips fraying on the end of shoelaces. Shortened telomeres have been linked to a host of age-related illnesses such as heart disease and certain cancers. (Scientists have yet to study whether telomeres influence a person's appearance.) Last year's Nobel Prize for Medicine was awarded to three American scientists...
