Looking at the solar photosphere, we see the top of the convection zone in the form of granulation: Hot gas rising from the solar interior as part of the energy transport process reaches a position where the opacity is no longer sufficient to prevent the escape of radiation. The gas expands, radiates, and cools and in so doing loses its buoyancy and descends. These motions, ultimately driven by...

according to reports about 30-thousand people spent watching television had the impact on their memory and recall that the results showed no differences between men and women. the people who watched less than an hour a day did better at every memory function. as these contributors watched negative political ads, physiological responses indicated that their body was reflexively preparing to move...

Carbon dioxide (CO2) levels in the atmosphere and surface ocean are rising at an unprecedented rate due to sustained and accelerating anthropogenic CO2 emissions. Previous studies have documented that exposure to elevated CO2 causes impaired antipredator behavior by coral reef fish in response to chemical cues associated with predation. However, whether ocean acidification will impair visual re...

Jupiter has half a dozen eastward jet streams in each hemisphere. On average, Earth has only one in each hemisphere. Jupiter has weather patterns (“storms”) that last for centuries. Earth has stationary weather patterns fixed to the topography, but the average lifetime of a traveling storm is ∼1 week. Jupiter has no topography, i.e., no continents or oceans; its atmosphere merges smoothly with ...

We have discovered a pulsating DA white dwarf at the lower end of the temperature range 45 000–30 000 K where a few helium atmosphere white dwarfs are known. There are now three such pulsators known, suggesting that a new class of theoretically predicted pulsating white dwarf stars exists. We name them the hot DAV stars. From high-speed photometric observations with the ULTRACAM photometer on t...
