Going to be fraught territory...
QUOTE
I suspect that IARC’s tenuous conclusion — that cell phones “may” be linked to cancer — will be fully justified by the research. It also will be largely ignored by the public, since most people long ago learned to discount cancer risk stories when the chemical or technology involved is extremely popular.

Wonder if it works the same way for humans as for rodents? Could have interesting implications for why/ how parental responsibility is typically & traditionally parceled out in early childhood (mostly to mothers):
QUOTE
In the current study, Dulac and her colleagues found that 61 percent of imprinted genes in the fetal brain are maternal in origin, suggesting a major maternal influence over the brain development of offspring. By adulthood, the proportions are flipped. About 70 percent of imprinted genes in both the adult cortex and hypothalamus appear to derive from the father, suggesting a major paternal influence on the brain function of adult offspring.

This new work expands on the known timeline for the internal conflict between maternal and paternal genes. Maternal genes may predominate in fetal development, followed by a period of childhood where maternal and paternal genes tussle for control, followed by eventual bias in favor of paternal genes during adulthood.

Many (145) comments on this blog post, based on a press release describing the petroleum or oil seeps from the ocean floor near Santa Barbara, California. One of the commenters points to Thomas Gold's work, too ("Deep Hot Biosphere," eg.). There is much we don't understand about the so-called "fossil" fuels...

File this under "I HEART biomimicry!" Amazing piece about scientists discovering that a lowly Brazilian beetle manufactures --chemically! -- scales that essentially function as a photonic crystal structure for visible light. Now the scientists are not only making molds or copies of the beetles amazing crystal structure embedded in its scales, but are trying to mimic (figure out) the chemical processes by which the beetle creates them in the first place.

(Note: I'm highlighting the entire article to have in my Diigo archive, as I've noticed that some MIT Tech Review articles disappear after a while.)

  • Researchers have discovered a species of Brazilian beetle that has the unusual trait of reflecting iridescent green from almost any angle. By examining the structure of the beetle's scales, scientists at the University of Utah found an ideal photonic-crystal structure for visible light--a type of material that optical scientists have been seeking for years.
  • Three-dimensional periodic structures called photonic crystals are potentially valuable materials for controlling photons; scientists could use photonic crystals operating at visible wavelengths to develop more-efficient solar cells, telecommunications, sensors, and even optical computer chips. A diamond-based structure, in particular, is thought to be the most effective three-dimensional photonic crystal for visible light, because it can reflect a wide band of colors and has high reflectivity. Less light escaping means researchers can better control and manipulate the photons.

BLDBLG reports on an article in Nature (magazine) that the "Earth beneath our feet might act as a gigantic circuit built by microbes to power their metabolic systems." Reminds me of Thomas Gold's theories.

  • It's not a planet at all, then, but a bio-electrical deposit rotating itself in space. A living battery.
  • And while that obviously sounds far-fetched, we actually read that these microbes function as a "geological battery," and that this battery is made from "networks of tiny wires linking individual bacterial cells into a web-like electrical circuit." These circuits could extend for miles – hundreds of miles – whole continents and island chains, linked by reefs.
