| Asparagus benefits from X-ray treatment Posted: 13 Dec 2011 08:47 AM PST Experiments to determine the effect of low-dose X-ray irradiation on asparagus found that the treatment significantly reduced aerobic bacteria and mold/yeast populations and helped to maintain sugar (glucose and fructose) levels. Researchers said that irradiation also temporarily increased Phenylalanine ammonia-lyase activity. The study results showed that X-ray treatment can enhance consumer safety and extend shelf life by decreasing the number of viable microorganisms on fresh-cut asparagus. |
| Changes in London taxi drivers' brains driven by acquiring 'the Knowledge' Posted: 08 Dec 2011 09:57 AM PST Acquiring 'the Knowledge' – the complex layout of central London's 25,000 streets and thousands of places of interest – causes structural changes in the brain and changes to memory in the capital's taxi drivers, new research has shown. |
| High intestinal microbial diversity safeguards against allergies, study suggests Posted: 08 Dec 2011 08:48 AM PST High diversity and a variety of bacteria in the gut protect children against allergies as opposed to some individual bacterial genera. These are the findings of a comprehensive study of intestinal microflora (gut flora) in allergic and healthy children. |
| Female fish choose sexier friends to avoid harassment Posted: 06 Dec 2011 09:07 PM PST Scientists have observed a strategy for females to avoid unwanted male attention: Choosing more attractive friends. The study is the first to show females spending time with those more sexually attractive than themselves to reduce harassment from males. The study focuses on the Trinidadian guppy, a species of small freshwater fish. The research shows that the tactic is successful and by ensuring they are less attractive than other group members, the fish experience less harassment and fewer mating attempts from males. |
