| Fighting infectious disease the modern way - with robots Posted: 21 Jun 2013 09:10 AM PDT Hospitals are synonymous with cleanliness and now an academic medical center is taking disinfection to futuristic levels. Nicknamed "little Joe" a 3-foot upright cylindrical robots provide the finishing touches to room sanitation. A rotating telescopic head emits cidal ultraviolet (UV) rays for 15 minutes in closed, unoccupied rooms to systematically kill germs dead.  |
| Bacterial DNA may integrate into human genome more readily in tumor tissue Posted: 20 Jun 2013 04:20 PM PDT Bacterial DNA may integrate into the human genome more readily in tumors than in normal human tissue, according to a new study. Researchers analyzed genomic sequencing data available from the Human Genome Project, the 1,000 Genomes Project and The Cancer Genome Atlas. They considered the phenomenon of lateral gene transfer, the transmission of genetic material between organisms in the absence of sex.  |
| Why our prehistoric, parasitic 'jumping' genes don't send us into meltdown Posted: 20 Jun 2013 10:22 AM PDT A new study reveals for the first time how the movement and duplication of segments of DNA known as transposons, is regulated. This prevents a genomic meltdown, and instead enables transposons to live in harmony with their hosts — including humans.  |
