| Biologists use Sinatra-named fly to show how to see the blues -- and the greens Posted: 09 Oct 2011 11:02 AM PDT Biologists have identified a new mechanism for regulating color vision by studying a mutant fly named after Frank ('Ol Blue Eyes) Sinatra. Their findings focus on how the visual system functions in order to preserve the fidelity of color discrimination throughout the life of an organism. They also offer new insights into how genes controlling color detection are turned on and off.  |
| Smarter toxins help crops fight resistant pests Posted: 09 Oct 2011 11:02 AM PDT An international collaboration has found that a small genetic manipulation restores the efficacy of crop-protecting toxins derived from bacteria against pest insects that have become resistant.  |
| Study shows how bookmarking genes pre-cell division hastens their subsequent reactivation Posted: 09 Oct 2011 11:01 AM PDT By observing and measuring the kinetics of activation of a single gene locus in a cell before it divides and comparing it with the same gene's reactivation in newly formed daughter cells, scientists have discovered how how bookmarking a gene pre-division causes it to get reactivated post-division.  |
| Gene technology can help food crops must to withstand harsher weather Posted: 07 Oct 2011 07:21 AM PDT Rapid population growth and a swiftly changing climate compound the challenges of ensuring a secure global food supply. Genetically modified plants could help to solve the problem, believes Norwegian a crop researcher. By 2050, 70 per cent more food will need to be produced worldwide on roughly the same area of farmland to keep up with global population growth. At the same time, major changes in climate are expected to occur. Some agricultural researchers believe that in order to ensure a secure global food supply, we will have to use every existing means -- including genetically modified organisms (GMO).  |
