Scientists discover new bases of DNA

For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis of the growing knowledge regarding how genes code for life.

Unanticipated structure at chromosome ends could be key ingredient in biological 'elixir of life'

In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists at the Salk Institute for Biological Studies have uncovered an important clue to one of the mechanisms underlying cancer cell immortality.

New research: Rhodopsin pigment in Drosophila may detect temperature

New research from Mount Sinai School of Medicine has discovered that rhodopsin, a pigment of the retina that is responsible for the first events in the perception of light, may also be involved in temperature sensation. This detection had not been revealed in previous studies.

Researchers unveil mechanism of candida infections

More than half of all people are hosts to Candida albicans in their bodies. This species might be located on their skin or mucous membranes or in the intestines frequently without causing any symptoms. However, it can be dangerous to patients whose immunological system has been weakened such as after organ transplants or chemotherapy with cancer. Then, this fungus penetrates into deeper layers of tissue and uses the blood system to spread throughout the body. In Germany alone, several thousand people die from systemic candida infections every year.

New DNA sequencing method can lead to effective individualized medicine

In experiments with potentially broad health care implications, a research team led by a University of Washington physicist has devised a method that works at a very small scale to sequence DNA quickly and relatively inexpensively.That could open the door for more effective individualized medicine, for example providing blueprints of genetic predispositions for specific conditions and diseases such as cancer, diabetes or addiction.
