3D printing used for stem cells
4 February 2013 Last updated at 20:05 ET A 3D printing technique that produces clusters of stem cells could speed up progress towards creating artificial organs, Edinburgh scientists have claimed. In the more immediate future it could be used to generate biopsy-like tissue samples for drug testing. The technique relies on an adjustable “microvalve” to build up layers of human embryonic stem cells (hESCs).
Tourists face health risks from contact with captive sea turtles
Feb. 5, 2013 Tourists coming into contact with sea turtles at holiday attractions face a risk of health problems, according to research published February 5 by JRSM Short Reports . Encountering free-living sea turtles in nature is quite safe, but contact with wild-caught and captive-housed sea turtles, typically through handling turtles in confined pools or through consuming turtle products, carries the risk of exposure to toxic contaminants and to zoonotic (animal to human) pathogens such as bacteria, viruses, fungi and parasites.
Bioelectric signals can be used to detect early cancer
Feb. 1, 2013 Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors
Spread of hepatitis C pinpointed
31 January 2013 Last updated at 22:57 ET Scientists say they have, for the first time, worked out the pattern of spread of hepatitis C, showing early diagnosis is key to preventing epidemics. A study in injecting drug users in Greece indicated that each infected person spread the disease to 20 others – 10 of these in the first two years
Longevity Gene: Discovery opens the door to a potential ‘molecular fountain of youth’
Jan. 31, 2013 A new study led by researchers at the University of California, Berkeley, represents a major advance in the understanding of the molecular mechanisms behind aging while providing new hope for the development of targeted treatments for age-related degenerative diseases. Older and fitter
Nanomaterials key to developing stronger artificial hearts
Jan. 31, 2013 ACS Nano published a study by Ali Khademhosseini, PhD, MASc, a researcher in the division of biomedical engineering at Brigham and Women’s Hospital, detailing the creation of innovative cardiac patches that utilize nanotechnology to enhance the conductivity of materials to induce cardiac tissue formation. Creation of these ultra-thin cardiac patches put medicine a step closer to durable, high-functioning artificial tissues that could be used to repair damaged hearts and other organs.
Peer pressure trumps ‘thin’ ideals in the media
