Agricultural and environmental challenges—including water management and climate change—as well as human health issues, from infectious diseases to cancers, are being evaluated as potential areas for future research collaboration between the United States and Uzbekistan, AAAS has reported.
Wild insects pollinate major agricultural crops—from cotton to blueberries—more effectively than hives of honeybees managed by humans, according to a massive international study.
In their report in the 1 March issue of Science, Lucas Garibaldi of Universidad Nacional de Río Negro in Argentina and colleagues also conclude that honeybees only add to the pollinating power of the wild insects, and can’t replace their pollination services.
For about 70 years, breeders have selected tomato varieties with uniformly light green fruit before ripening. These tomatoes then turn red evenly as they ripen, and they look nice in a supermarket display.
Researchers now have pinpointed the molecular changes responsible for this “uniform ripening” trait of many modern tomatoes. But these changes, they show, also reduce the fruit’s sugar content.
