Researchers conducted a randomized experiment and found that diners at full service restaurants whose menus listed calories ordered meals with 3 percent fewer calories — about 45 calories less — than those who had menus without calorie information. Customers ordered fewer calories in their appetizer and entree courses, but their dessert and drink orders remained […]

Researchers have now identified three new molecular drug targets in Naegleria fowleri and a number of drugs that are able to inhibit the amoeba’s growth in a laboratory dish. Several of these drugs are already approved by the US Food and Drug Administration for other uses, such as antifungal agents, the breast cancer drug tamoxifen […]

Researchers have created a massive database of the changes in gene activity of individual cells in the cerebellum during embryonic development and immediately after birth. The analysis of thousands of brain cells isolated from mice offers researchers a high-resolution map that enables scientists to view the detailed genomic changes cells undergo as the cerebellum wires […]

Leptospirosis infections, caused by Leptospira bacteria, occur in people and animals around the world, but different strains of the bacteria may vary in their ability to cause disease and to jump between species. Now, researchers have for the first time described the characteristics of the Leptospira variants that infect cattle in Uruguay. Source: Leptospirosis strains […]
