Chinese scientists for first time successfully clone monkeys

Chinese scientists for first time have successfully cloned two identical long-tailed macaques (monkeys), named Zhong Zhong and Hua Hua using same technique that produced Dolly sheep two decades ago. This development makes them world’s first primates – the order of mammals that includes monkeys, apes and humans – to be cloned from non-embryonic cell. Key Read More…

Scientists for first time grow skeletal muscle tissue from stem cells

Scientists from Duke University in North Carolina, US for first time have developed working human skeletal muscle from stem cells in the laboratory. Stem cells Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide to produce more stem cells. They are found in multicellular organisms. In mammals, there are Read More…

Scientists create world’s smallest data recorder from bacteria

Researchers from Columbia University Medical Centre (CUMC) in US have converted natural bacterial immune system into the world’s smallest data recorder. The researchers modified an ordinary laboratory strain of ubiquitous human gut microbe (bacteria) Escherichia coli (E Coli) which enabled it to record their interactions with environment and also time-stamp events. Key Facts The microscopic Read More…

Three US-born scientists win 2017 Nobel Medicine Prize

The 2017 Nobel Prize in Physiology or Medicine was awarded to Jeffrey C. Hall (72), Michael Rosbash (73) and Michael W. Young (68). It was announced by Nobel Assembly at Sweden’s Karolinska Institute. ‎They were awarded for discovering molecular mechanisms controlling circadian rhythm. Their discoveries explain how plants, animals and humans adapt their biological rhythm Read More…
