Graphene transistor, SEM - Stock Image SN8923
Graphene transistor. Colored scanning electron micrograph (SEM) of a transistor composed of a graphene wire (center), gold electrodes (dark yellow) and silicon (blue). The graphene wire is 200 nanometers (billionths of a meter) wide. Graphene is composed of a single layer of carbon atoms arranged in a honeycomb crystal lattice. It is both flexible and very strong. It conducts electrons faster than silicon and could one day replace silicon in applications such as nanometer (billionths of a meter) sized electronics, inexpensive and efficient solar panels, transparent window coatings and miniature sensing technologies. Graphene was discovered by Andre Geim in 2004.

Kepler Mission's exoplanets, artwork. NASA's Kepler Mission (not shown) is a space telescope designed to discover Earth-like planets orbiting other stars. Examples of such planets are shown here, including Earth-like planets, Martian planets, Venusian planets, Jovian planets and Saturnian planets. Kepler's 0.95-meter diameter photometer will scan 100,000 stars in the Milky Way for evidence of Earth-sized terrestrial planets that transit the star's path. The mission was launched on March 7th, 2009, and is named in honor of German astronomer Johannes Kepler. As of February 2011, over 1000 candidate planets have been discovered.

Repeated Concussions Caused by Repeated Attempts to Injure Head (playing Football)

A 3D illustration of whiplash, an injury caused by the sudden acceleration and deceleration of the head and neck. This type of injury is most commonly seen in rear-end motor vehicle collisions, resulting in hyperextension of the muscles and ligaments of the neck. There can also be damage to the cerebrum similar to a concussion as the head snaps back and forth, causing the brain to shift inside the skull.

Henrietta Lacks (1920-1951), was an African-American cancer victim and the unwitting donor of cells from her cancerous tumor, which were cultured by George Otto Gey to form a cell line for medical research. This is known as the HeLa cell line. HeLa cells are the first human cell line. They were obtained in 1951 from Lacks' cervix. She died of cervical cancer eight months later, and the cells are named for her. Her cancer was an epidermoid carcinoma. HeLa cells thrive in laboratory conditions and are now used in cancer research worldwide.

Messier 42, M42, NGC 1976, Orion Nebula, Trapezium - BV1289

STOCK IMAGE NUMBER: BV1289

NASA's Spitzer and Hubble Space Telescopes have teamed up to expose the chaos that baby stars are creating 1,500 light-years away in a cosmic cloud called the Orion nebula. This striking infrared and visible-light composite indicates that four monstrously massive stars at the center of the cloud may be the main culprits in the familiar Orion constellation. The stars are collectively called the "Trapezium." Their community can be identified as the yellow smudge near the center of the image. Swirls of green in Hubble's ultraviolet and visible-light view reveal hydrogen and sulfur gas that have been heated and ionized by intense ultraviolet radiation from the Trapezium's stars. Meanwhile, Spitzer's infrared view exposes carbon-rich molecules called polycyclic aromatic hydrocarbons in the cloud. These organic molecules have been illuminated by the Trapezium's stars, and are shown in the composite as wisps of red and orange. On Earth, polycyclic aromatic hydrocarbons are found on burnt toast and in automobile exhaust. Together, the telescopes expose the stars in Orion as a rainbow of dots sprinkled throughout the image. Orange-yellow dots revealed by Spitzer are actually infant stars deeply embedded in a cocoon of dust and gas. Hubble showed less embedded stars as specks of green, and foreground stars as blue spots. Stellar winds from clusters of newborn stars scattered throughout the cloud etched all of the well-defined ridges and cavities in Orion. The large cavity near the right of the image was most likely carved by winds from the Trapezium's stars. Located 1,500 light-years away from Earth, the Orion nebula is the brightest spot in the sword of the Orion, or the "Hunter" constellation. The cosmic cloud is also our closest massive star-formation factory, and astronomers believe it contains more than 1,000 young stars. The Orion constellation is a familiar sight in the fall and winter night sky in the northern hemisphere. The nebula is invisible to the unaided eye, but can be resolved with binoculars or small telescopes. This image is a false-color composite where light detected at wavelengths of 0.43, 0.50, and 0.53 microns is blue. Light at wavelengths of 0.6, 0.65, and 0.91 microns is green. Light at 3.6 microns is orange, and 8.0 microns is red.

Streptomyces Colony
Streptomyces Colony - BD3603
Colony of the soil bacterium Streptomyces lividans. Streptomyces species are natural producers of a number of antibiotics including streptomycin. Members of the Actinomycetes group, they share many characteristics with the fungi. The bacteria grow in the soil as a branching network of filaments known as a mycelium. They also produce aerial mycelium on the tips of which develop chains of spores. When the spores are mature, they rupture and are dispersed into the air.
