Animals will not only die if they remain in regions affected by global warning, they will not know what they are doing. Research shows that rising carbon dioxide changes the behavior of fish. Carbon dioxide makes the acidity of ocean water rise. Like humans, fish rely on nerve cells to "perceive" the environment they live in, like detecting hot and cost, pain or painless. They also have to rely on environmental cues to behave in a particular way. Fish smell predators so they normally move away from them, but high acidity in the water makes the smell attractive. Small fish move too close to predators, so they are easily caught and eaten. Fish behave this way due to their nerve cells trying to maintain a balance with the environment. With a rise in carbon dioxide and acidity, bicarbonate and chloride levels rise inside nerve cells, so a feeling of security is not turned off by the smell of predators. A switching chemical, GABA, becomes irregular opening nerves which

For years we have been told that subliminal messages on television and in films has no affect on us. Now we are informed that they do indeed work very well. It is known that people pick up signals by intuition from other people. For example, poker players seem to know when their opponent has a good or bad hand. They don't know how - they just do. A study sandwiched a subliminal picture for less than 50 milliseconds between two "normal" images. The subjects could then choose between two symbols, one being the sandwiched picture, to win money. The result was, subjects actually made money. MRI scans done at the time identified the ventral striatum region of the brain being the most active during the intuitive tests. The research shows that subliminal advertising having a reward system attached can increase sales of a product. We can anticipate an increase in subliminal advertising. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ ht

Long, saberlike teeth could have been a disadvantage for the saber tooth tiger. With a trapped animal struggling with all its strength to escape there is a high probability that the teeth could have been broken. Broken teeth would have significantly reduced the effectiveness of an attack on prey. The tigers would have gone hungry. Members of the cat family living today have quite short "fangs", too short to break off in a tussle. Fossils show that ancient cats had long canine teeth and very strong forelimbs. The bones of forelimbs were thick. Cross section analysis of their teeth showed they were oval, whereas modern cats are round. Being oval they could More easily snap off. Prey had to be firmly held so they could be dispatched quickly. The longer the fangs, the sturdier the forelimbs. This is the rule when comparing similar ancient long toothed animals. This highlights convergent evolution, where complimentary traits evolve in different animals filling simila

Hunting animals don't just eat what they "bump into". They select "who" they need to eat to maintain a healthy diet. This gives them a better chance of growing strong and big so they can reproduce and pass on their genes. A team from the University of Sydney, Oxford University, Aarhus University (Denmark) and Exeter University researched the ground beetle (Anchomenus dorsalis). Beetles were divided into three groups: one had a selection of bugs offered to them; the second group had high-protein food; and the third had high-fat offerings. The latter two groups did not fair very well. Those in the first group did very well. They chose ants, slugs, moths, aphids and beetle larvae as they wanted and produced more eggs than the other two. It was known that herbivore and omnivore insects ate varied diets. This study confirms the view that all animals select their food due to inner craving created by the body based on the body's immediate needs. The pr
