| Tangled up in DNA: New molecule has potential to help treat genetic diseases and HIV Posted: 14 Feb 2012 10:49 AM PST Chemists have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.  |
| People forage for memories in the same way birds forage for berries Posted: 14 Feb 2012 10:48 AM PST Humans move between 'patches' in their memory using the same strategy as bees flitting between flowers for pollen or birds searching among bushes for berries.  |
| Bumblebees get by with a little help from their honeybee rivals Posted: 14 Feb 2012 09:18 AM PST Bumblebees can use cues from their rivals the honeybees to learn where the best food resources are, according to new research. In a new study, researchers trained a colony of bumblebees (Bombus terrestris) to use cues provided by a different species, the honeybee (Apis mellifera), as well as cues provided by fellow bumblebees to locate food resources on artificial flowers.  |
| The indiscretions of a champagne bubble paparazzi Posted: 14 Feb 2012 07:09 AM PST The innermost secrets of champagne bubbles are about to be unveiled by a scientist tackling champagne bubbles from both a physics and a chemistry perspective. To understand what appears to be a harmless phenomenon such as the fizz in champagne, the author studied the role of the carbon dioxide throughout its journey from the bottle to the glass.  |
| Turmeric-based drug effective on Alzheimer flies Posted: 14 Feb 2012 07:05 AM PST Curcumin, a substance extracted from turmeric, prolongs life and enhances activity of fruit flies with a nervous disorder similar to Alzheimer's disease, according to new research. The study indicates that it is the initial stages of fibril formation and fragments of the amyloid fibrils that are most toxic to neurons.  |
| Posted: 13 Feb 2012 10:34 AM PST An expert says that a genome, rather than a static collection of information, is a dynamic structure itself, responding to stress and contributing to our genetic development. His re-conception of the genome has the potential to provide deeper insight into how all living organisms evolve.  |
