Autographs of Lightning in Power Lines
Experiments in the southern Alleghenies examine how lightning discharges affect electric power lines. A direct strike can halt service. even nearby bolts induce surges that may raise voltage dramatically in a fraction of a second. New apparatus captures these surges at lightning speed, showing lightning writing its own records.

Wood-Derived Food Report Signals New Animal Feed
German chemists announce a discovery turning wood into nutritious substance for herbivores after processing 100 parts of dry wood yields 15 parts of fodder. The method uses concentrated hydrochloric acid to dissolve cellulose and aims to extend to straw and green twigs for potential human consumption.
Scent Trails and Fox Hunting Tactics
