Scientists say bees can count to four
Researchers have discovered that honey bees can count to four. A researcher from the University of Queensland put five markers inside a tunnel and placed nectar in one of them, Australian Broadcasting Corporation (ABC) radio reported. Honey bees placed in the tunnel flew to the marker with the food, and would still fly to the same marker stripe when the food was removed. "We find that if you train them to the third stripe, they will look subsequently in the third stripe," researcher Mandyam Srinivasan said. "If you train them to the fourth stripe, they will look the fourth stripe and so on. But their ability to count seems to go only up to four. They can't count beyond four.
Tai chi cuts pain
The traditional Chinese form of exercise known as tai chi can help reduce pain and physical impairment in people who have knee arthritis, researchers said on Saturday. In their study, one group of people in their 60s with severe knee osteoarthritis performed tai chi for an hour twice a week for 12 weeks while a similar group did the same amount of conventional stretching exercises over the same period. Those who did tai chi experienced greater pain reduction, less depression and improvements in physical function and overall health, researchers led by Dr. Chenchen Wang of Tufts Medical Center in Boston reported at a meeting of the American College of Rheumatology in San Francisco. The study provided the latest evidence that tai chi may offer benefits for people with arthritis. The Arthritis Foundation advocacy group recommends it for improving the quality of life of people with arthritis.
