Tufts nutrition scientists say it is premature to focus on nutrient supplements over diet
...sease. In one study, adding a nutrient antioxidant cocktail to a well established cholesterol-lowering drug treatment actually lessened the beneficial effect. "We still have a lot to learn about the use of high doses of nutrients. The important point is to prevent the cart from getting in front of the horse; ...... researchers said. The study finds that a hormonal cocktail routinely used in the lab induces a key genetic switch in the transition from fat-cell precursors to full-blown fat, researchers at University of Michigan Life Sciences Institute report in the September Cell Metabolism.

...ed dementia and others who did not. The well-known cocktail of antiretroviral drugs prescribed to most HIV patients has cut the number of HIV-associated dementia cases reported each year, Gonzalez-Scarano said. However, this is because the drugs slow the progression of the disease, he said. Patients still hav...How the brain sorts babble into auditory streams

Corn plants emit a cocktail of scents when they are attacked by certain pests, such as a caterpillar known as the Egyptian cotton leaf worm. Parasitic wasps use these plant scents to localize the caterpillar and deposit their eggs on it, so that their offspring can feed on the ...Evolution mystery: Spider venom and bacteria share same toxin
...Arizona. The toxin is uniquely found in the venom cocktail of brown or violin spiders, including the brown recluse, and in some Corynebacteria. The toxin from the spider's venom can kill flesh at the bite site; the bacterium causes various illnesses in farm animals.
