It’s fascinating to consider how different animals, in their own ecological niche, can be similarly successful using such different strategies.” About this memory research newsĬontact: Melissa Bradshaw – Queen Mary University London Ms Yonghe adds: “Despite what may seem to be a poor memory strategy, bumblebees do very well in finding the most profitable flowers. Maybe because bumblebees evolved to mostly only eat flower nectar, they never needed to remember the details and could survive and thrive simply using simple comparisons.” Prof Fei Peng, senior author currently at Southern Medical University, China, states “It may be that the different strategies used by bumblebees and humans may have evolved because of their different diets. Ms Yonghe Zhou, co-lead author on the paper and currently a PhD student at Queen Mary University of London, says: “Our results reveal an intriguing divergent mechanism for how bumblebees retain and use information about options, compared to humans and birds.” Over a series of experiments, bumblebees’ preferences during the tests indicated that they could only retain very basic ranking memories for the flowers for very long. Starlings, a bird native to Europe, and the only other animal for which this question has been examined, similarly use a combination of absolute and comparative information when remembering options. Previous research shows that we humans actually keep memories for both absolute information (e.g. Bees couldn’t seem to remember for more than a few minutes how sweet or rewarding the flowers were on their own or even how much sweeter they were compared to other flowers. The bumblebees could only remember that a flower had been better or worse during training phase. Then bumblebees were given the choice between two of the flowers they hadn’t seen together before, for example the second and third or the first and third. Later, they learned that a third flower was sweeter than a fourth flower. In new research in the journal eLife, bumblebees were first trained on two flowers, learning that one flower was sweeter than a second flower. Tournament of Roses president Amy Wainscott chose Giffords as “a perfect example of how to valiantly turn the corner.Summary: Bumble bees don’t retain memories of how sweet a flower is, they only remember if one flower was sweeter than another.īumblebees don’t seem to keep memories for how sweet a flower was, but instead only remember if it was sweeter than another flower, according to researchers at Queen Mary University of London, along with an international team of scientists. “I chose to make a new start, to move ahead and not look back.” Mine did when I was shot but I never gave up hope,” Giffords told the crowd. Because of the severe brain injury she suffered, she had to re-learn how to walk and talk. Giffords, 52, was shot in the head in January 2011 outside a Tucson, Arizona, grocery store during a public appearance.
