Pair says ‘dark energy’ dominates the universe

A Dartmouth researcher is building a case for a “dark energy”-dominated universe. Dark energy, the mysterious energy with unusual anti-gravitational properties, has been the subject of great debate among cosmologists. Brian Chaboyer, Assistant Professor of Physics and Astronomy at Dartmouth, with his collaborator Lawrence Krauss, Professor of Physics and Astronomy at Case Western Reserve University, have reported their finding in the January 3, 2003, issue of Science. Combining their calculations of the ages of the oldest stars with measurements of the expansion rate and geometry of the universe lead them to conclude that dark energy dominates the energy density of the universe.

Calorie listings don’t encourage overeating, study says

You really don't want to knowLabeling foods “low-fat” is suspected of encouraging consumers to overeat. If that box of Ho-Ho’s claims to be low-fat, heck, why not down the full dozen? But a study from Penn State says the same is not true of the listing of caloric content. “Some studies have shown that people take larger portions of foods labeled ‘low fat’ ? using the label as a license to eat more. This study shows that energy density labels are unlikely to undermine the benefits of offering foods with fewer calories per ounce.”
