Railgun technology could supplant conventional weapons
Livermore and Los Alamos researchers develop a direct current linear induction railgun powered by a million ampere pulses. The device uses copper rails and a plastic projectile to create plasma propulsion, potentially exceeding ballistic speeds and enabling space launch capabilities.

Weather and sun impact on earth heat balance
The article explains how insolation heats the earth, noting atmospheric transport of heat, absorption and reflection of solar radiation by clouds, water vapor, and ground cover. It covers cloud effects on radiation, ground reflectance for fields and forests, snow reflectivity, and the limited role of water surface heat versus soil conduction.

Proto star may form from small gas cloud in Orion region
A dark gas cloud in Orion may be a proto star as scientists James Palmer of Chicago University and colleagues Mark Morris of Columbia and B Zuckerman report in the Astrophysical Journal. The cloud, about 20 solar system diameters across, could collapse to form a star over tens of thousands of years. In a separate note, Cornell researchers domesticate queen yellowjackets in cages to study venom production for medical protection.
