Preliminary numbers from the U.S. Department of Agriculture (USDA) suggest that the population of domesticated US honeybees is still declining. The loss in pollinators is due in part to the effects of pesticides but also to natural stressors like the varroa mite, which can infect whole bee colonies. To learn more about how to monitor the health of hives, researchers and the computer technology company Oracle are joining forces. VOA's Kevin Enochs reports.
In Congo, more than 600 people have contracted the Ebola virus which has claimed close to 400 lives. The disease has been difficult to contain because of conflict in the region, despite an effective vaccine. But now, VOA's Carol Pearson reports, health workers may soon be able to cure those with the disease.
Researchers are already using sensors on drones to monitor farmers fields and provide a whole host of statistics from moisture levels to pesticide loads. But drones are energy intensive and expensive. Researchers at the University of Washington have created tiny sensors that can hitch a ride on bees that are already floating among the fields. VOA's Kevin Enochs reports.
A new form of social therapy is powering-on in the U.S. A group of former toy company employees bought a brand from their ex-employer and started developing robotic household animals that serve as friends and therapy aids to America's growing elderly population. Arash Arabasadi reports.
Cancer in your esophagus, the tube that runs from your throat to your stomach, is one of the most frequently reported and a leading cause of cancer deaths around the world. Most cases are reported in developing countries. Early esophageal cancer typically causes no symptoms. However, its chemical markers are present in the earliest stage. A new device being tested in England takes advantage of that to allow early detection of esophageal and other types of cancer. Faith Lapidus reports.
