Exercise during leisure time may reduce the risk of 13 types of cancers, including liver cancer and breast cancer, a major study said Monday. Hundreds of previous studies have examined associations between physical activity and cancer risk and shown reduced risks for colon, breast, and endometrial cancers. However, these results have been inconclusive for most cancer types due to smallRead more

Researchers have developed a bio-glass material that not only mimics the shock-absorbing and load bearing qualities of real cartilage, but potentially encourages it to re-grow, according to a press release published Thursday by the Imperial College London. Cartilage is flexible connective tissue found in places such as in joints and between vertebrae in the spine. Compared to other types ofRead more

The International Society for Stem Cell Research (ISSCR), the largest international professional organization of stem cell scientists, on Thursday released newly updated guidelines aimed at promoting "responsible" stem cell research. "The field of stem cell research is growing at a rapid pace, with scientists and physicians developing new therapies that can help patients around the world who suffer from aRead more

Archaeologists working in the 600-year-old Forbidden City, or officially known as the Palace Museum, in Beijing have discovered foundations of buildings from an even earlier dynasty at the site. Underneath the former royal palace used by the Ming and Qing dynasties (1368-1911) are foundation remains that could be from as early as the Yuan Dynasty (1271-1368), said Li Ji, aRead more

Patients undergoing emergency surgery in lower income countries have a three times greater chance of dying than in higher income countries, according to a study released Wednesday by the University of Edinburgh. Researchers from the Universities of Edinburgh, Birmingham and Sheffield monitored post-surgery death rates and mapped them against the Human Development Index (HDI) of various countries. Some 10,745 patientsRead more

US doctors have shown for the first time that soft tissue surgery can now be performed entirely by a robot, putting surgery one step closer into the realm of intelligent machines. The so-called Smart Tissue Autonomous Robot (STAR) succeeded in suturing and reconnecting bowel segments in living pigs, a procedure known as intestinal anastomosis, and all the animals survived withRead more

Australian scientists have teamed up with China's National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) to develop crucial technology in the world's largest single-dish telescope. The Commonwealth Scientific and Industrial Research Organization (CSIRO) revealed on Thursday that it would offer a significant contribution to the Five hundred meter Aperture Spherical Telescope (FAST) project, with its scientists set toRead more

Feels bursting anger during air travel? It is probably only because your flight has a first-class cabin and you have to walk past it before finding your own seat, a new study shows. The study, published Monday in the Proceedings of the National Academy of Sciences of the United States of America, is co-authored by Katy DeCelles of the UniversityRead more

A team of Chinese and French speleologists have determined that China's longest cave is around 186 kilometers long, 25 kilometers longer than a measurement from 2014. The cave researchers conducted a joint expedition from April 16 to 28 at Shuanghe Cave in Wenquan Township, Suiyang County in southwest China's Guizhou Province. They also discovered fossils of vertebrates at 13 sitesRead more

German researchers have developed self-propelled tiny microbots that can remove lead or organic pollution from contaminated water, said the Max Planck Institute Stuttgart on Friday. Working with colleagues in Barcelona and Singapore, German researchers used graphene oxide to make their microscale motors, which are able to adsorb lead from industrial wastewater from a level of 1,000 parts-per-billion to down toRead more
