The human body is under natural continuous evolution. Be that what it be then, black box theory tells us that the best way to find out what's going on 'inside the box' (and we happen to be inside the box) is to 'test' it in as simply a way possible because the more variables operating, the harder it is to separate what affects what. Iron is very likely only one of 'god-knows-how-many' variables may be tweaking human genes. -And there's the problem, we haven't the vaguest idea what we're doing to the system, but economic growth'(*l) goes on; pollution is affecting both ecosystems and the genetics of various organisms thruout the world -multiple legs, die-offs, sex changes et cetera; polar bears are drowing as global warming melts ice beneath them -and it goes on -'Rome is burning'.
How's the family???

Polar Bears' Troubling New Prey: Polar Bears

From Times Staff and Wire Report

Polar bears in the southern Beaufort Sea may be turning to cannibalism because longer ice-free seasons are making it more difficult to hunt the ringed seals that are its principal food source.
   A study published in the online version of the journal Polar Biology reviewed three examples of predation from January to April 2004 by polar bears, including the first-ever reported killing of a female in a den shortly after giving birth.
   Polar bears do kill each other for dominance and breeding rights. But killing for food appears to be a new behavior, said principal author Steven Amstrup of the U.S. Geological Survey Alaska Science Center.

Iron Boost in Infants May Lead to Parkinson's

Mice fed levels similar to those in some formulas later showed signs of neurodegeneration.
By Erin Cline, Times Staff Writer

Exposure to levels of iron similar to those infants get from fortified baby formula may increase the risk for developing Parkinson's disease later in life, according to a study released Thursday.
   It has long been known that patients with the neurodegenerative disorder have increased iron levels in their brains. However, it is unclear whether this increase is a cause or an effect of the disease.
   Efforts to correlate increased brain iron levels with adult dietary intake or occupational exposure have been inconclusive.
   A team of researchers led by Julie Andersen at the Buck Institute in Novato, Calif., found that when mice were fed iron during the period of their development corresponding to humans' first year of life, iron accumulated in their brains, and they developed signs of neurodegeneration as they aged.
   The mice were given iron doses equivalent to the amount a human baby absorbs when fed iron-fortified formula, which typically provides 12 times more iron than breast milk, researchers said.
   Iron is added to baby formula to ensure that infants have an adequate supply for proper blood and brain development.
   "I don't want to imply that people should stop using formula," said Andersen, whose study was published in the journal Neurobiology of Aging. Instead, she said, her research suggests that epidemiological studies should be conducted in humans, and perhaps the levels of iron added to formula should be reevaluated.
