Sound

Sound is the mechanical propagation of vibrational waves from the jostle of atoms. From a physiological and psychological standpoint, sound is the sensation of such waves in an audible frequency range.

Toll Roads

Filamentous fungi grow by hyphal branching and extension, creating networks which serve as highways for motile soil bacteria on the go. But the bacteria must pay a toll for traveling fungal roads.

Viral Editing

Viruses selectively edit host genetic instructions to produce the bioproducts they want as part of viral reproduction. Viruses can do this because they understand life at the molecular level.

Asphalt

Vehicles are a major contributor to polluting emissions which damage health and foster global warming. So too are the asphalt roads which they ride upon.

Climate Sensitivity

There is no simple formula for how fast Earth is hotting up. If there were, 2 key components in the equation would be greenhouse gas emissions and temperature sensitivity to those emissions. Those 2 factors suggest that Earth is racing toward hellish heat.
