Is Chocolate Good For The Body?Researchers have shown that eating a small amount of dark chocolate each day can thin the blood and prevent it from clotting. Dark chocolate can be used as a substitute for aspirin. It also lowers blood pressure and has other effects on blood flow. A performed experiment showed that the blood of the participants who stayed away from chocolate clotted faster than those who ate the chocolate.
However, while eating chocolate may be desirable and beneficial, Vicky Evans, a cardiac nurse, suggests that there are better ways to take care of the heart. Adding a moderate amount of chocolate to a daily diet should be fine. Eating some dark chocolate can be good for the body, but too much chocolate increases the amount of sugar in the blood. Before running to the candy store, Vicky Evans suggests eating about five portions of fruits and vegetables a day.

Although the casualties have not been determined, the meteorological agency issued a tsunami warning in Japan. In response, thousands of Japanese residing along Japan 's Northern Pacific coast relocated to higher ground for safety. Hours after the earthquake, the same meteorological agency rescinded its warning.
Japanese residents are no strangers when it comes to such excitement. As one of the world's most earthquake-ravaged countries, Japan has instituted drills and government campaigns to inform citizens that tremors can potentially lead to tsunamis. Japan's Meteorological Agency is prepared to declare a tsunami warning even when the agency anticipates only minor waves. Furthermore, Japan’s most populated coastlines are wired with loudspeakers in the event of tsunami evacuations. Tsunami advisories for Russia, Alaska, the Philippine Islands, Taiwan, Indonesia and several Pacific islands were later withdrawn as well.

These dogs were treated with infusions of a certain type of stem cell called mesoangloblast. Muscular dystrophies are a common genetic disorder in which muscles gradually break down and which may lead to paralysis and death. The stem cells in the experiment were taken from the blood vessels of healthy dogs. In the sick dogs, the stem cells functioned by moving through the vasculature into the muscles, fusing with existing muscle cells, and producing the missing protein needed for normal function. These types of stem cells, identified by the team in humans, could now be studied in people with muscular dystrophy. Mesoanglobalsts hold the special advantage of being able to move through the bloodstream, so they could be simply injected into the blood.
While stem cells have the potential to regenerate many kinds of failing tissue, they have not yet advanced through clinical trials to actual treatments. This study, published online in the magazine Nature, raises further questions, such as whether this kind of therapy can work on the heart muscle and diaphragm, which are also affected in muscular dystrophy, and whether the injected stem cells might produce negative side effects in other parts of the body. Another complication the treatment might hold for humans is the reaction of the sick person’s body against the infused foreign cells: the patient would have to take lifelong immunosuppressant drugs to combat this effect. Current clinical trials are investigating other innovative therapies for muscular dystrophy, such as using viruses to deliver the missing gene to muscle cells.

The heart’s reparative cells resemble stem cells in their ability to transform into adult tissue, with a few advantages. According to the study’s lead researcher, Dr. Paul Riley, “this approach would bypass the risk of immune system rejection, a major problem with the use of stem cell transplants from another source.” Dr. Riley added that the research would have “the added benefit that the cells are already located in the right place—within the heart itself,” unlike stem cells, which come from the bone marrow.
The experiments with adult mice proved the cells’ potential to repair damaged blood vessels and the heart tissue itself. Researchers hope that this will open doors to a more effective way of preventing and treating heart disease—an illness that claims lives of more than 105,000 people in the UK, and over 700,000 in the US.

The project stems from the desire to remove barriers that supposedly infringe upon the freedom of people who are restricted by traffic signs that dictate what they should do on the road. Ideally, both pedestrians and drivers would communicate by way of gestures, eyes contacts, head nods, and verbal cues. Already implemented in a small Dutch province, proponents claim that the lack of traffic lines, parking meters and signs would increase social responsibility by making pedestrians and drivers aware of their actions towards others.
The presence of traffic laws has bred resentment within drivers who are forced to obey these rules. Manners disappear as people try to secure their advantage on the road. Envisionists foresee drivers and pedestrians “blending into a colorful and peaceful traffic stream.” And the best part, all asphalt will be removed and replaced with cobblestone paths. Save for the presence of a horse and buggy, it looks like modernity is a thing of the past.
