Induced pluripotent stem cells (iPS cells) can be transformed into any cells in the body or maintain their original form. In a new study, researchers from research institutions such as the Helmholtz Center in Germany described how cells decide which of these two directions to choose. In their research, they identified a protein and a ribonucleic acid (RNA) that played a very important role in this process. Their findings also…

New Research Reveals How Light-sensitive Proteins Regulate Skin Tone
A team at Brown University found that Opsin3 is a protein closely related to rhodopsin, a protein that enables low-light vision. It regulates the amount of pigment produced in human skin, which is a determining factor in skin color. When humans spend their time in the sun without proper skin protection, the sun’s ultraviolet (UV) radiation sends a signal to the skin that produces more melanin – which prevents…
