A team of researchers at Columbia Engineering and Columbia University Medical Centre announced today the results of the first study comparing bone structure in Chinese-American women to Caucasian women. The report, just presented at the Orthopaedic Research Society's annual meeting at Long Beach, CA, found that pre-menopausal Chinese-American women have far greater bone strength than their Caucasian counterparts, as determined by a breakthrough technological advance…
In research described as 'a stark warning' to those tempted to start smoking, scientists are reporting that cigarette smoke begins to cause genetic damage within minutes - not years - after inhalation into the lungs…

Scientists have identified a protein that acts as a 'master switch' in certain white blood cells, determining whether they promote or inhibit inflammation. The study, published in the journal Nature Immunology, could help researchers look for new treatments for diseases such as rheumatoid arthritis that involve excessive inflammation…
Shoulder motion after rotator cuff surgery remains significantly different when compared to the patient's opposite shoulder, according to a Henry Ford Hospital study…
Researchers are using inexpensive components from ordinary liquid crystal display (LCD) projectors to control the brain and muscles of tiny organisms, including freely moving worms. Red, green and blue lights from a projector activate light-sensitive microbial proteins that are genetically engineered into the worms, allowing the researchers to switch neurones on and off like light bulbs and turn muscles on and off like engines…
In a technique that could eventually shed light on how gene expression influences human disease, scientists at Albert Einstein College of Medicine of Yeshiva University have for the first time ever successfully visualised single molecules of naturally-occurring messenger RNA (mRNA) transcribed in living mammalian cells. The scientific achievement is detailed in the January 16 online edition of Nature Methods…
