Beautiful Death: Halos Of Planetary Nebulae Revealed
- ScienceDaily
- 08/9/12 03:30
Stars without enough mass to turn into exploding supernovae end their lives blowing away most of their mass in a non-explosive, but intense stellar wind. Only a hot stellar core remains in the form of a white dwarf; the rest of the star is dispersed into the interstellar medium, enriching it with chemically processed elements, such as carbon, that is found in all living organisms on Earth. These...

Remote Brainwaves Predict Future 'Eureka' Moment
- ScienceDaily
- 08/9/12 03:30
The brain mechanism underlying the eureka or "ah-ha" moment is poorly understood. What happens in the brain during that particular moment? Is that moment purely sudden as often reported by the solver or is there any (neural) precursor to it? Can we predict whether and when, if at all, the solver will hit upon the final eureka moment? New research addresses these questions by measuring brainwaves...
