Alfalfa hay, cut and baled for fodder, is a source of protein that rivals or surpasses soybeans. Technology that makes possible the extraction of nutrients from this and other non (human)-food sources on land and in the sea can increase the Earth's food potential. (Author/BT)

Discusses how technological advancement, in particular: the explosion in useful wavelengths and the revolution in telescope design and fittings, multiplies astronomers' grasp of the cosmos. (HM)

Organic v inorganic dichotomy in chemistry has begun to disappear while a new formal research discipline, bioinorganic chemistry, is emerging. The field has been developed with the realization that a third of all proteins and bioenzymes contain an inorganic element such as a metal critical to their chemical nature. (Author/RE)

The presence of gravitational waves was predicted by Einstein in his theory of General Relativity. Since then, scientists have been attempting to develop a detector sensitive enough to measure these cosmic signals. Once the presence of gravitational waves is confirmed, scientists can directly study star interiors, galaxy cores, or quasars. (MA)
