There are special diseases that are so old that it is known that even Egyptian mummies and tsars’ families were suffering from them. No medications have been yet created to cure them, and no doctor can help get rid of such diseases. Doctors say that such diseases that are called hereditary diseases emerge as a result of natural selection. These diseases are programmed to progress only.

It has been estimated that ten percent of people worldwide suffer from Restless Leg Syndrome. RLS is a neurological disorder that makes it difficult to sit or lie still for long periods of time. The disorder often occurs in the evening and at night, so falling sleep or staying asleep is especially difficult for those who have it.

Scientists have found clusters of new gene variants that raise the risk of Type 2 diabetes - and how the researchers did it is as important as what they found. In one of the largest studies yet of human genetic variability, the scientists tested the DNA of more than 32,000 people in five countries to pin down spots that harbor genetic risk factors for this complicated killer.

Diabetes and high blood pressure, two conditions rooted in genetics and environmental surroundings, play a much greater role than race alone in determining who is mostly likely to develop heart failure, according to the latest study from cardiologists at Johns Hopkins. Each year, nearly 300,000 Americans die from heart failure.

A long-term research project at the University of Missouri-Columbia is producing valuable information about alcoholism and individuals who are affected by a family history of the disease. MU psychology researchers, now several years into a multi-year study, have discovered that individuals from alcoholic homes maintain personality traits that could eventually lead to alcohol dependency.

In families with a high incidence of Li-Fraumeni syndrome, the ends of individuals' chromosomes act somewhat like a lit fuse, according to researchers at The Hospital for Sick Children in Toronto. Their findings detail how telomeres, the ends of the chromosomes, shorten with every successive generation, leading to more severe cancers at an earlier age.

While previous biomedical research studies have found that genetics and race increase risk for some diseases, a new look into how researchers study genetic triggers of type 2 diabetes suggests that defining race remains an inexact science, with social and historic facts mixing with biology throughout the research process.

Sifting through the pages of newspapers, most people reading stories about autism would think scientists are primarily grappling with understanding how environmental factors, such as childhood vaccines, might contribute to the condition. But the truth is quite different. The efforts of the scientific community to explore autism lie predominantly in brain and behavior research.
