Emery Brown's research provides insight into why the doses required to achieve an anesthetic state differ among age groups. In one study, the anesthetic-induced brain waves of older adults were two to three times smaller than those of younger ones. As we age, Brown explains, brain cells function at a lower level, so weaker brain waves can disrupt their activity and cause unconsciousness. more »

Like fireworks bursting through a smoky haze, protostars ignite within colossal filaments of gas in a new supercomputer simulation of stars forming inside molecular clouds. The simulation covers 700,000 years, and is based on computer code created by UC Berkeley astrophysicist Richard Klein to capture the effects of radiation, magnetic fields, gravity and other physical phenomena and paint a realistic portrait of star formation. more »

" ... Stevens received few accolades for her efforts in piecing together chromosomal sex determination. This was due in part to her early death, in 1912, from breast cancer — a mere seven years after her work was published. Conflicting views made the scientific community slow to accept her conclusions, which today are recognized as pioneering." more »

Joan L. Cannon writes: When the first brilliant leaps of credibility struck the known universe, from ancient civilizations that modern Man has unearthed and learned to interpret, to the 21st Century comprehension of such things as the 'God particle' and the elasticity of gravity, nuclear physics, genetics, brain imaging — the minute human place in what's out there becomes ever smaller. more »
