Restoring Fish Populations Leads To Tough Choice For Great Lakes Gulls |
 |
You might think that stocking the Great Lakes with things like trout and salmon would be good for the herring gull. The birds often eat from the water, so it would be natural to assume that more fish would mean better dining. But a new report published in the journal Ecology says that restoring fish has not been good for the birds. |

What Does The Label On Your Chicken Really Mean? |
|
|
Buying chicken these days is not like it used to be. With labels like "100 percent natural," "organic," "grain-fed," and "free range," many consumers don't really know what they're buying. According to the U.S. Department of Agriculture "100 percent natural" means the poultry doesn't contain artificial ingredients like preservatives. But experts warn--there are no guarantees. |

Fruit Fly Avoidance Mechanism Could Lead To New Ways To Control Pain In Humans |
|
|
At first, fruit flies eat like horses. Hatching inside over-ripe fruit where they were laid, they feed wildly in the sugar-rich environment until nature sends them an offer they can't refuse. To survive, they must leave the fruit, wander off and burrow into the earth where they avoid food as if it were poison. Only then can the larvae grow and hatch into flies that will take wing to lay their own eggs. Researchers have now discovered that the important developmental switch from food attraction to aversion in the fruit fly larva is controlled by a timing mechanism in the brain and its sensory system. The study shows how this important avoidance mechanism has been recruited into evolutionary processes to promote development and could lead to new methods of controlling pain in humans and other animals. |

Nitrates In Vegetables Protect Against Gastric Ulcers, Study Shows |
|
|
Fruits and vegetables that are rich in nitrates protect the stomach from damage. This takes place through conversion of nitrates into nitrites by the bacteria in the oral cavity and subsequent transformation into biologically active nitric oxide in the stomach. This also means that antibacterial mouthwashes can be harmful for the stomach. |
