Mexican Salamander offers hope to amputees

Scientists have genetically modified a salamander mexican strange appearance, which according to a myth azteca is a god transformed, with the hope that their ability to regenerate parts of your body helps some day to people with amputations.
Also known as "monsters water", the ajolotes are near extinction in their last stronghold natural: some contaminated channels to the south of the City of Mexico, where circulating dozens of rafts multicolored stroll tourists and bands of mariachis.
But the baboso pet, 15 centimeters long, crowned by a series of furry gills, and small black eyes and button, is a success in laboratories, where achieves played with ease.
The ajolote has become the consent of many researchers thanks to its ability to regenerate both their limbs wounds as the jaw, skin, organs and even parts of the brain and spinal cord.
Other animals can regenerate, but only the salamanders can grow again many parts of your body several times over his life.
The Department of Defense of the United States has donated 6.5 million dollars to scientists who study to this strange creature with the intention of which may help in the future to the more than 1,000 soldiers who lost a limb in the wars in Iraq and Afghanistan.

In a mexican laboratory, where biology students detailing the increasingly reduced natural habitat of the animal, a ajolote whose leg was torn by a fellow pond develops as a small replica, with fingers included. "The humans can repair tissue, but do not repaired to perfection.

The ajolote, under certain circumstances, you can enter a condition where repeats the process of when he was embryo," said Elly Tanaka, the center for regenerative therapies in Dresden, Germany.
They believe that only takes a decade, or two, so that human limbs can regenerse like salamanders.

Adrenaline

Adrenaline is a hormone action, secreted by the adrenal glands in response to a hazardous situation.
Adrenaline acts mainly on muscle, adipose tissue and liver. Begins to secrete in a matter of seconds, but a peak occurs when you reach the moment of production. Its effectiveness lies between one and three minutes and has the ability to increase the body's normal metabolism as much as 100 percent.
Given the risk, the adrenal glands secrete adrenaline, which relaxes the muscles of the airways to allow more air to enter the lungs, stimulates the heart and makes it beat faster and harder, the pupils dilate to increase the ability to observe, the respiration rate increases and slows the digestive system so that more blood to enter the muscles, which increases stress and blood pressure.

extreme sports

Extreme sports are all activities or disciplines that already exist in most, but that due to special circumstances or situations as implicit danger and difficulty of achieving them, are considered extreme. Some are extreme sports: skydiving, flying paragliding, rafting or river rafting, mountain biking, rock climbing, bungee jump, hiking, diving, motor, espeología etc.

Benefits of laughter.

When we laugh exercise: Each carcajada are launched approximately 400 muscles, including the stomach that can be exercised only with laughter.

- Serves as a massage: The cervical spine and that is where we usually accumulate tension, stretch to laugh. It also stimulates the spleen and removes toxins. With this move the diaphragm creates an internal massage that facilitates digestion and helps reduce the fatty acids and toxic substances.

- We clean: The laugh was clean and lubricate the eyes with tears. Laughter vibrate his head and clears the nose and ear.

- Oxygenation: When you laugh twice as air enters the lungs, so the skin becomes more oxygenated. Specifically, the lungs move air 12 liters instead of the usual 6, which improves breathing and increases oxygenation. This belies the idea that laughter causes wrinkles on the face, unlike the tones.

Consumption of salt in Mexico.

Mexican consumes twice daily salt accepted as healthy, "Each year, the IMSS provides more than 13 million visits for hypertension. All this is related to the fact that the average Mexican eats about five grams of salt a day, when is that a normal healthy adult consumes only 2.5 grams and a child case 750 milligrams.

Also salt consumption leads to excess cases of other diseases such as blood pressure, a disease that causes cardiovascular problems, chronic renal failure and stroke.

Sedentary life.

In Mexico there are over 350 thousand people affected by Alzheimer's, and over two thousand die each year because of this disease. Most alarming is that while one per cent suffers from genetic, 99 percent is purchased by risk factors such as age, a sedentary life, lack of cognitive stimulation or a diet high in calories and fat. This disease could be caused by the toxicity of two proteins of the body that trigger pathological aging.

CLIMATE IN THE FUTURE.

In the short term, is more acute the effect of global warming looming in greenhouse gases, caused largely by human action. These gases have risen since the industrial phase of human significantly: The third has increased CO2, methane has doubled, and nitric oxide has grown by 15%. If only this increase continues, it is estimated that in 100 years the Earth average temperature will increase between 2 and 5 degrees. This overall increase in temperature would bring major consequences: loss of forest fires in the forest, so that means, changes in precipitation with an atmosphere more unstable, with frequent storms and floods, increased evaporation and thus of aridity, melting glaciers with a consequent rise in sea levels, flooding of coastal regions with their cities, salinization of coastal aquifers; mass death of coral reefs ... There are opinions that suggest that the problem is not so alarming: forests absorb excess CO2 and above all, oil will be exhausted by 2100 and will lower greenhouse gases significantly. But it is prudent not to play with a very delicate and interconnected with the biosphere as the climate and it would be possible to reduce human emissions of greenhouse gases from industries and transport. One solution is the gradual replacement of "dirty energy", based on fossil fuel, "clean energy", no contaminants, such as wind, solar, hydro, biomass, and above all, to investigate and capitalize on other energy, cleaner and more powerful, such as fusion, which is the energy of stars, among others.
