Our human body is very complex, and every organ or body part has its own importance that's usually noticed when we have a problem with tha specific part. In the following infographic we learn more about the foot, it's common problems and how to avoid them. For example, having a good hygiene and walking regularly will keep your feet in good shape and ready to carry you around for many years. Also, at the bottom of the infographic you will learn which exercises to follow in order to have healthy feet. Via: MiToe

Folks who consume baked or baked fish every week could be ameliorating their brain wellness and cutting down their risk of getting mild cognitive impairment (MCI) and Alzheimer's disease. The study establishes a direct connection between fish eating habbits, brain structure and Alzheimer's risk. "The results showed that people who consumed baked or broiled fish at least one time per week had better preservation of gray matter volume on MRI in brain areas at risk for Alzheimer's disease." Alzheimer's disease is an incurable, graduated brain disorder that slowly ruins memory and cognitive skills. National Institute on Aging reports that 5.1 million US citizens may have Alzheimer's disease. In MCI, blackout is present but it's not that aggressive. Folks with MCI usually go on to germinate Alzheimer's disease. "Consuming baked or broiled fish promotes stronger neurons in the brain's gray matter by making them larger and healthier,...

Researchers at the University of Edinburgh, Scotland are workin on a type of artificial blood that will be ready for human tests in two or three years. The artificial blood is created from divisible stem cells harvested from adult bone marrow. The fresh created blood will be O Negative and could be used for 98% of patients. Basically, blood is a liquid material that carries oxygen and other nutrients through the veins and arteries. Every day people are injured or develop problems that requires surgery. This means blood loss requires transfusion of fresh blood from various donors. In some cases this could be a problem because the blood type could be hard to find, especially in underdeveloped countries. In addition, there are external risks of blood infections such as HIV, hepatitis, etc. The team from Edinburgh, led by Professor Marc Turner, is cultivating stem cells from bone marrow in a material very similar to red blood cells. They believe that the mechanism is refined and will...

I'm sure everyone heard about foods that are not good for your health: pork, fats, junk food, etc. But what should we eat and how should we treat our body in order to live longer? If you want to have a healthier and longer life then you should eat natural food. Stop buying from your local drugstore pills stuffed with  large complex of vitamins. Nutritionists advise you to try a cheaper and safer option. Why pay for pills when you can pay for the real deal? "We know that fruit and vegetable diet is healthy, that prevents many diseases and reduces costs for maintaining health. Unfortunately, nobody knows exactly how each component of this regime affects the longevity of life" said Dr. Hubert Warner, who runs an aging program research. This does not mean it won't affect it. Almost every study available shows that fruit and vegetable is the simplest way to keep your body in shape. Another study shows that chocolate and wine are the secret of a long healthy life....

Artificial blood vessels created in the laboratory with a 3D printer  could be used in organ transplantation soon . The major obstacle encountered so far in creating artificial tissues was supplying them with nutrients, which is done naturally through capillaries. A team of researchers from the Fraunhofer Institute in Germany has solved this problem by using a 3D printer and a technique called two-photon polymerisation. There are thousands of patients who desperately needed a transplant and some fail to obtain it in time. Over 11,000 people were put on the waiting list for organ transplantation in Germany only in 2011. To save as many lives as they can, researchers around the world working in the field of tissue engineering have attempted to create in the laboratory artificial tissues and even whole organs. "The individual techniques are already functioning and they are presently working in the test phase; the prototype for the combined system is being built," ...

Superstring theory is an effort to find an answer for all of the atoms and cardinal forces of nature in one hypothesis by molding them as oscillations of tiny supersymmetric strings. Superstring theory is a stenography for supersymmetric string theory because contrary to bosonic string theory, it's the adaptation of string theory that contains fermions and supersymmetry. Physicist Brian Greene gives a short explanation of superstring theory, a concept that minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.
