Americans and Cubans learned from success stories and brainstormed how to address shared challenges at a high-level symposium on the future of the United States-Cuba scientific cooperation in Havana from March 20-21, 2023.
AAAS and the Cuban Academy of Sciences signed an updated Memorandum of Understanding that lays out a path for cooperation on scientific issues of mutual interest.
PARIS—A widely used insecticide can threaten the health of bumblebee colonies and interfere with the homing abilities of honeybees, according to a pair of new studies. The reports, one by a U.K. team and one by a French team, were published 29 March at the Science Express Web site of the journal Science.
Bumblebees and honeybees are important pollinators of flowering plants, including many major fruit and vegetable crops. Each year, for example, honeybee hives are driven from field to field to help pollinate almond, apple, and blueberry crops, among others.
Researchers in Texas have discovered thousands of human artifacts in a layer of earth that lies directly beneath an assemblage of Clovis relics, expanding evidence that other cultures preceded the Clovis culture in North America. This pre-Clovis toolkit appears to be between 13,200 and 15,500 years old and it includes biface and blade technology that may have later been adapted—and improved upon—by the Clovis culture.
For his novel research to obtain high-resolution images of biological cells and tissues, Mark Bates has been named the 2010 Grand Prize winner for the GE & Science Prize for Young Life Scientists. The annual competition, which includes a grand-prize award of $25,000, is supported by GE Healthcare and the journal Science, which is published by AAAS, the nonprofit science society.
