Except for the fat content of the herring, the nutrient content was the same for both groups, Polasek explained. The researchers monitored the animals in the low fat group to ensure fat intake...Highlights of American Chemical Society meeting in Atlanta, March 26-30
...e nuts, a key ingredient of pesto, may help people lose weight by suppressing their appetite. The compound, pinolenic acid, is an oil found in unusually high levels in the Korean pine nut, which appears in laboratory studies to stimulate the release of two appetite-suppressing peptide hormones, CCK (chole...The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

...ts a cow's nervous system and causes the animal to lose much of its movement before it eventually dies. More than 180,000 cases of BSE have been confirmed worldwide, including recent cases in the United States. The disease can be passed to humans, and more than 100 such cases have been confirmed, most of ...Cancer cells lose drug resistance following electrical stimulation in vitro
Drug-resistant tumour cells lose their drug resistance when exposed to low intensity, low frequency electric pulses for three days. A study published today in the open access journal BMC Cancer reveals that treating drug-resistant tumour cells with electric pulses in vitro restores ...Media alert: New study finds dairy is not associated with weight gain
...ain," Miller said. "If you're cutting calories to lose weight, it's important to get your 3 servings of dairy foods each day for good health and to enhance your weight loss efforts." Though more research is needed to fully understand the relationship between dairy and weight, experts suggest this emergin...Tomorrow's endangered species: Act now to protect species not yet under threat

Species in these 'hotspots' have a latent risk of extinction; that is, they are currently less threatened than their biology would suggest, usually because they inhabit regions or habitats still comparatively...JCI table of contents: March 1, 2006

...this idea of redundancy in ecological systems: You lose one species, but another replaces its function," Micheli said. "In the case of grazers, 90 percent of urchins in one system were depleted, but their function was replaced by parrotfishes. Unfortunately, when you look at these small communities in the......zoos. In response to this isolation, many species lose the ability to respond appropriately to their predators. However, some species, despite many years of isolation, retain anti-predator behavior.
