| Odors from human skin cells can be used to identify melanoma Posted: 13 Jun 2013 12:33 PM PDT Researchers identified odorants from human skin cells that can be used to identify melanoma, the deadliest form of skin cancer. In addition a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells. Non-invasive odor analysis may be a valuable technique in the detection and early diagnosis of human melanoma.  |
| Medieval leprosy genomes shed light on disease's history Posted: 13 Jun 2013 11:26 AM PDT Scientists have reconstructed a dozen medieval and modern leprosy genomes -- suggesting a European origin for the North American leprosy strains found in armadillos and humans, and a common ancestor of all leprosy bacteria within the last 4000 years.  |
| Light-carved 'nano-volcanoes' hold promise for drug delivery Posted: 13 Jun 2013 07:44 AM PDT Researchers have developed a method for creating "nano-volcanoes" by shining various colors of light through a nanoscale "crystal ball" made of a synthetic polymer. These nano-volcanoes can store precise amounts of other materials and hold promise for new drug-delivery technologies.  |
| Gene offers an athlete's heart without the exercise Posted: 13 Jun 2013 07:41 AM PDT Researchers have found that a single gene poses a double threat to disease: Not only does it inhibit the growth and spread of breast tumors, but it also makes hearts healthier.  |
| Smart technology makes its way into lighting Posted: 13 Jun 2013 06:22 AM PDT The lighting systems of the future could be multi-purpose devices not dissimilar to smart phones. In the future, lighting will not just allow us to see but could also be used to survey surroundings, transmit information, reflect moods and make our lives more comfortable. Smart lighting could also save as much as 80 per cent of energy compared to traditional lighting solutions.  |
