Tips To Slim Down Your Pet

fat_dog_006

* Take an objective look at the food you are feeding your dog. Many commercial foods lack sufficient nutritious ingredients in addition to lacking freshness. As a result, the dog continually craves more food and is more prone to health problems. It may be time to upgrade to a super premium food or to a home-made diet, or something in-between, such as supplementing a super premium dry food with whole foods such as fresh vegetables and yogurt.

* You can help an overweight dog lose weight by cutting back on the regular dog food and adding vegetables. The vitamins and extra roughage will help. Suggestions about healthy foods appear later in this article. As for healthful dog foods, read articles on the internet, such as those listed at the end of this tipsheet.

* If you stick with the same food, reduce the amount by 25 percent. You should see results in two weeks. If he hasn’t slimmed down, cut back his food a little bit more, but do not make drastic reductions. Gradual weight loss is preferred; for many breeds, one pound a week is plenty. If you don’t see results in a month, consult your vet — and reconsider the type of food you’re using.

* You should not try to eliminate all fat from a dog’s diet. Just reduce the amount of fat intake. Remember, some fats are better than others. For example, flaxseed oil, fish oil and other foods that contain omega 3 and 6 fatty acids are beneficial and essential for humans and canines alike. The same cannot be said for things such as animal fat and the trans fat prevalent in cookies, chips and certain dog treats.

Pig Lungs Could Soon Be Transplanted Into Humans

A6W4DK

Pig lungs could be transplanted into humans to overcome a shortage of donor organs after a medical breakthrough.Australian scientists have paved the way for animal-human transplants in as little as five years, after keeping pig lungs alive and functioning with human blood.The breakthrough came after scientists at Melbourne’s St Vincent’s Hospital were able to remove a section of pig DNA called the Gal gene, which made the pig organs incompatible with human blood.

Prof Tony D’Apice – who has been breeding pigs for possible transplants since 1989 – said human DNA was added to the engineered animals to control blood clotting and rejection in humans.Dr Glenn Westall, from the Alfred Hospital in Melbourne, said the world-first discovery meant pig-human lung transplants were a real prospect.

He said: ‘Five to six hours into the experiment they seemed to be working as well as they were at the start.’The blood went into the lungs without oxygen and came out with oxygen, which is the exact function of the lungs.’It showed that these lungs were working perfectly well and doing as we were expecting them to do.”This is a significant advance compared to experiments that have been performed over the past 20 years.’

Ants More Rational Than Humans

In a study released online on July 22 in the journal Proceedings of the Royal Society: Biological Sciences, scientists at Arizona State University and Princeton University show that ants can accomplish a task more rationally than our multimodal, egg-headed, tool-using, bipedal, opposing-thumbed selves.
This is not the case of humans being “stupider” than ants. Humans and animals simply often make irrational choices when faced with very challenging decisions, note the study’s architects Stephen Pratt and Susan Edwards.

“This paradoxical outcome is based on apparent constraint: most individual ants know of only a single option, and the colony’s collective choice self-organizes from interactions among a number of poorly-informed ants,” says Pratt, an assistant professor in the School of Life Sciences in ASU’s College of Liberal Arts and Sciences.

The authors’ insights arose from an examination of the process of nest selection in the ant, Temnothorax curvispinosus. These ant colonies live in small cavities, as small as an acorn, and are skillful in finding new places to roost. The challenge before the colony was to “choose” a nest, when offered two options with very similar advantages.

What the authors found is that in collective decision-making in ants, the lack of individual options translated into more accurate outcomes by minimizing the chances for individuals to make mistakes. A “wisdom of crowds” approach emerges, Pratt believes………
