【文章內容簡介】 ees could perform arithmetic operations like addition and subtraction (減法). Solving math problems requires a plex level of involving the mental management of numbers, longterm rules and shortterm working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence, particularly in improving rapid learning. RMIT39。s Professor Adrian Dyer said numerical (數字的) operations like addition and subtraction are plex because they require two levels of processing. “You need to be able to hold the rules around adding and subtracting in your longterm memory, while mentally using skillfully a set of given numbers in your shortterm memory,” Dyer said. “On top of this, our bees also used their shortterm memories to solve arithmetic problems, as they learned to recognize plus or minus as abstract concepts.” The findings suggest that advanced numerical cognition (認知) may be found much more widely in nature among nonhuman animals than previously suspected. “If math doesn39。t require a massive brain, there might also be new ways for us to include interactions of both longterm rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer. Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more plex level of processing. Previous studies have shown some primates (靈長目動物), birds, babies and even spiders can add and/or subtract. The new research, published in Science Advances, adds bees to that list.（1）What have the researchers from RMIT University discovered?

The study reports the newlydeveloped rice produces proteins that attach directly to the HIV virus. This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading. The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly twothirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease. The new study predicts the ricebased method will lead to longterm use of the antiHIV treatment across the developing world. Researchers said the groundbreaking discovery is realistically the only way that antiHIV bination treatments can be produced at a cost low enough for the developing world. They say the easiest and most costeffective way to use the rice will be to make it into a cream to be put on the skin. The HIVfighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine. The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the gene
