In English: Cinder, the naked chimpanzee
Escrito por Aberrón a las 8:36 | 27 comentarios »
Cinder is a hairless chimpanzee living at St Louis zoo (US). She looks like an old wise monkey, but she's actually 13 years old. When she was born, August 1994, she had a beautiful, full coat of hair, but she began to loose her hair after some months. A year later, Cinder was completely bald.
During the first months of life Cinder was treated with all kind of medications, but in the end nothing helped. Cinder was diagnosed with alopecia areata,which is also a human disease.
Alopecia areata “is a highly unpredictable, autoimmune skin disease resulting in the loss of hair on the scalp and elsewhere on the body". This common but very challenging and capricious disease affects approximately 1.7 percent of the population overall, including more than 4.7 million people in the United States alone” according to the National Alopecia Areata Foundation. When there is a total loss of hair, as in the case of Cinder, the condition is referred to as alopecia universalis.
According to the zoo, Cinder is otherwise a normal, healthy chimpanzee and, unlike humans, is not faced with the psychological and social challenges the disease presents. Cinder has never been treated differently by her parents or foster siblings, as beauty is in the eyes of the beholder and hair is not essential quality in the eyes of chimpanzees.

In the last ten years, commercial airlines are flying north of the Arctic Circle in a growing number of new routes between North America and Asian cities. These new cross-polar routes provide an attractive shortcut to Asia, which saves some hundreds of millions on fuel and time. Since 1993, when Russia agreed to open its territory, flight times have been cut by more than four hours in some of these routes, but actually there are several important risks that every passenger should know.
Across the nigthFlying over the North Pole is still a kind of adventure. According to Leo Brooks, an international senior captain for Continental Airlines, airplanes travel at an altitude of 31,000 to 39,000 feet and they generally fly 100 miles to the left or right of the North Pole. Right over the Artic, there is no traditional air traffic control and no radar. Air traffic control uses traditional radio position reports, a relatively old fashioned method, to keep track of the aircraft. If the airplane crashed or had any problem at this moment, it would be too far away from any inhabited area.
Because of the extended flight duration and the prevalence of very cold air masses on the polar routes, the potential exists for fuel temperatures to approach the freezing point. However, current airplane systems and operating procedures provide confidence that fuel will continue to flow unobstructed to the engines. Computer alarms go off if the fuel starts solidifying and, in that case, the pilots fly to a warmer altitude and alter the route.
Currently, United Airlines, with 1500 flights a year, is the leader in transpolar flights between America and Asia. The next closest passenger airline in terms of polar flyovers is Continental Airlines (796), folllowed by Air Canada (515) and some Asian airlines as Air China or Singapore Airlines. Thanks to these new airways, transport officials estimate that New York to Honk Kong takes five hours less than conventional routes, and Toronto to Beijing provides a four hours saving.
Radiation riskOn the other hand, recent studies show that passengers and crew members flying on transpolar routes are exposed to unusually high levels of cosmic and solar radiation. According to Robert Barish, a New York health physicist who recently spoke to the International Herald Tribune, the dosage received during each flight along the transpolar route is equivalent to three chest X-rays and may be significantly increased by solar flare radiation.
Heavy doses of radiation can cause damage to a developing fetus, provoke cancer or produce genetic mutations in human egg and sperm cells. This higher exposure on polar flights is due to the magnetic attraction that the polar region exerts on charged radioactive particles from space. Besides, the fact that atmosphere is getting thinner at the polar regions doesn't make the problem better.Under normal conditions, any air travel involves greater exposure to cosmic and solar radiation than staying on the ground. The U.S. FAA recommends that airlines inform their flight crews of the risks. On declaration of pregnancy, a crew member must immediately switch to low-exposure flights, and some European airlines go further and ground expectant mothers until after maternity leave.
So far, the airlines flying the North Pole route say they do not inform passengers of the increased cosmic radiation risks. At the same time, scientists and airline employees unions, have expressed concern about this risks an think the airlines should inform pregnant passengers and frequent fliers about the high radiation associated with these routes.

The location is at the Eisbach, which translates to 'ice river', just inside the Englischer Garten in Munich. The standing wave can be surfed the whole year, but the water is always very cold.
Well known and internationally recognized surfers started their careers in Munich. Techniques and manovers were adapted from surfing in the sea and tricks like aerials, 360s and floaters are common on the riverwave.
Nowadays, surfing is a very popular sport in Munich and they celebrate an international festival, the Munich Surf Open, which takes place in the natural wave of the river "Floßlände". Famous names in riversurfing come for the festival every year. Talking again about the Eisbach spot, the river flows out of a tunnel under the city. And surfers must be careful, as the rock is only about 40cm below the surface.
Curiously, the surfing is not allowed at the Eisbach and the sign you can see in the picture reads: surfing and bathing is forbidden. But it seems quite difficult to forbid anything when people is having such a great time.

The military’s relationship with the chimps began in the 1950s, when the U.S. Air Force collected more than 100 chimpanzees from Africa. More than 65 of them were shipped to Holloman Air Force Base in New Mexico to undergo tests on the effects of space flight.
The chimps were exposed to adverse conditions in order to make space travel possible. The tests included spinning the chimps in a giant centrifuge, exposing them to powerful G-Forces, and measuring how long it took one of the animals to lose consciousness in a decompression chamber. Strapped into small capsules, they were spun, jettisoned, and catapulted on track courses. During those years some of the monkeys were literally used as crash test dummies. According to some sources, some of the capsules were designed to accelerate to speeds of 400 miles per hour before coming to an abrupt halt. A sudden stop at such high speeds caused the chimpanzee’s brain to literally smash against the skull, resulting in massive trauma and death.
In 1961, three months before Alan B. Shepard became the first U.S. astronaut to travel in space, an American chimpanzee named Ham rocketed beyond the earth’s atmosphere in a Mercury capsule. Ten months later, another chimp, named Enos, successfully orbited the earth. But once America made it to space, the chimps were no longer of any use, so the Air Force began leasing its chimp colony to medical laboratories. Since 1970, more than a hundred of the chimps were awarded to the Couston Foundation, a toxicology lab in New Mexico that used chimps in AIDS and hepatitis experiments. The chimps were poked, injected with diseases and operated. Many lived for several decades in small cages, and most of them became sick and depressed.
Fortunately, Dr. Carole Noon thought that the captive chimps deserve better and sued the Air Force for custody, with the help of some important primatologists. After a year-long court battle, Noon gained permanent custody of 21 chimps, survivors of the "chimpanaut" program, and founded “Save the Chimps”.
Since 1997, the vision of Save the Chimps was - and remains - to create a Sanctuary where rescued chimpanzees can live out their lives without the threat of ever returning to a laboratory. These chimpanzees, who once had the "right stuff" for the space program, are now free to live out their lives in a more natural, peaceful environment. However- and that's for sure - they will never be able to forget the nightmare of those Space years.
