It's the fiber! It's the beta-carotene! No, it's the phytoestrogens! Scientists have been trying to figure out why vegetarians have only about half the cancer risk of meat-eaters. The latest plant supernutrient, beta-sitosterol, was lauded at the Federation of American Societies of Experimental Biology by University of Buffalo nutrition researcher Atif Awad, Ph.D. Beta-sitosterol was shown to inhibit the growth of breast cancer cells in the test tube, cutting the number of cancer cells by 66 percent compared with control cell cultures. Dr. Awad had previously found that beta-sitosterol inhibited prostate cancer cell growth but did so by a different mechanism, inhibiting an enzyme called PP2A, which is involved in cell growth.

animals are smarter than you think by Virginia Morell source: national geographic In 1977 Irene Pepperberg, a recent graduate of Harvard University, did something very bold. At a time when animals still were considered automatons, she set out to find what was on another creature's mind by talking to it. She brought a one-year-old African gray parrot she named Alex into her lab to teach him to reproduce the sounds of the English language. "I thought if he learned to communicate, I could ask him questions about how he sees the world." When Pepperberg began her dialogue with Alex, who died last September at the age of 31, many scientists believed animals were incapable of any thought. They were simply machines, robots programmed to react to stimuli but lacking the ability to think or feel. Any pet owner would disagree. We see the love in our dogs' eyes and know that, of course, Spot has thoughts and emotions. But such claims remain highly controversial. Gut instinct is not science, and it is all too easy to project human thoughts and feelings onto another creature. How, then, does a scientist prove that an animal is capable of thinking—that it is able to acquire information about the world and act on it? |

slaughterhouse video gets hallmark meat packing co. employees charged
A California prosecutor filed animal cruelty charges Friday against two former employees of Hallmark/Westland Meat Packing Co., reports UPI. The U.S. Department of Agriculture shut down the Chino, Calif., slaughterhouse last week after a video from the Humane Society of the United States showed slaughterhouse workers at the Southern California facility forcing disabled cows to their feet using sticks, electric prods and water hoses. San Bernardino County District Attorney Michael Ramos said five felony counts of animal cruelty and three misdemeanor counts were filed against Daniel Ugarte Navarro, 49, of Pomona, Calif., and three misdemeanor counts against Luis Sanchez, 32, of Chino. "It doesn't matter whether the mistreated animal is a beloved family pet or a cow at a slaughterhouse," Ramos said in statement. "Unnecessary cruelty will not be tolerated and will be prosecuted to the fullest extent allowed by law." USDA issued a statement Friday in support of the charges. "It is regrettable that these animals were mistreated and I am encouraged and supportive of these actions by the San Bernardino District Attorney in response to this mistreatment," Agriculture Secretary Ed Schafer said. As the USDA investigated animal cruelty charges brought about by the release of the horrifying video - taken by an undercover agent for the Humane Society investigating the Hallmark Meat Packing Co. slaughterhouse - the plant had their license suspended. Background The U.S. Department of Agriculture announced an investigation into charges of inhumane treatment of disabled cattle at a California slaughterhouse after the Humane Society released a videotape taken by one of their undercover workers showing the cold-blooded abuse of already sick and injured cows unable to walk to their own deaths. |
