Stem Cells

SK7017 - Stem cells, colored scanning electron micrograph (SEM). Stem cells can differentiate into any other cell type. There are three main types of mammalian stem cell: embryonic stem cells, derived from blastocysts; adult stem cells, which are found in some adult tissues; and cord blood stem cells, which are found in the umbilical cord. The cells seen here are destined to become blood cells. During blood cell development in adults, stem cells develop through a process known as hemopoiesis. Blood cells have short lifespans and are therefore constantly produced by the bone marrow. © Science Source - science photos

Solar Cell

GA4403 - Light micrograph (LM) of silicon solar cell. Close-up of the surface of solar (photovoltaic) cells, which convert light into electrical energy. Cells are made from a semi-conductor such as silicon (as here). When light hits it it releases electrons, which are converted into an electrical current. A grid of thin wires collects the electrons. These are polycrystalline (amorphous) cells, made from numerous small silicon crystals. This type of cell is less efficient than a single-crystal cell, but is far cheaper to manufacture. Solar power is an environmentally-friendly energy source. It does not use up limited resources and does not release toxic waste products.
