FURNACES OUTLAST NEW HEATING SYSTEMS AND SOLAR PROMISE
The old home furnace will stay in use for years despite new smokeless furnaces and solar heating ideas. Experts advise better firing, reduced heat loss, improved insulation and regular chimney cleaning to maximize heat from fuels. Solar and earth heat show potential but storage remains costly. MIT and other colleges test systems using heat storage chemicals like Glauber’s salt to store heat for night use.

New Theory Links Lysozyme to Ulcers and Colitis
Scientists from Columbia Presbyterian Medical Center report lysozyme may trigger both stomach ulcers and ulcerative colitis by dissolving protective mucus in the stomach and colon. Increased lysozyme was found in patients with ulcers and colitis, while nerve cutting reduced stomach lysozyme levels. Nisulfazole, an anti lysozyme sulfa drug, showed potential for treatment.
