The document summarizes 20 science images selected as the science photos of the year 2015 by the Wellcome Image Awards. The images cover a broad range of scientific topics and imaging techniques, including 3D printed lungs, the nervous system of a fruit fly, the internal structures of goat and horse stomachs and uterus, a microscopy image of a natural killer immune cell, illustrations of plant pollen and a boll weevil, a cross section of a cat's tongue, a reconstruction of a rare New Zealand reptile, color-coded images of a mouse brain and dendritic trees in a rat brain, metabolites in a mouse kidney, a brain cell taking up a carbon nanotube, a parasitic wasp, a greenfly eye

1. Science Photos Of The Year 2015
Science has a way of surprising even the most jaded observer, and that's certainly the case
with the images selected for the Wellcome Image Awards 2015. The science images of the
year feature cutting-edge technology and the hard work of researchers and their
institutions. A panel of judges selected 20 images from the many acquired by the
Wellcome Images library over the past year; the 20 will be honored at a March 18
ceremony, where an overall winner will be announced.
The 20 images cover a broad range of scientific topics, imaging techniques and materials.
One photo from Dave Farnham depicts 3D-printed human lungs inside the rib cage of a
woman with Hodgkin's lymphoma. The 3D rendering was created using data from her
CT scans.
This is not abstract art, but a re-creation of the nervous system in a fruit fly larva. Albert
Cardona, HHMI Janelia Research Campus, Wellcome Images.

2. The reticulum, or stomach chamber of a goat. The opening in the center leads to another
stomach chamber, the omasum. Goats have four stomach chambers -- the rumen, the
reticulum, the omasum and the abomasum. Courtesy of Wellcome Images.

3. A 3D structured illumination micrograph -- photo taken through a microscope -- of a
natural killer cell that's part of our innate immune system. "NK cells produce toxic
substances (cytotoxic) which when delivered to a susceptible target cell causes it to
self-destruct (apoptosis or programmed cell death)." Courtesy of Wellcome Images.

cancer. Courtesy of Wellcome Images.

Image of a boll weevil's head. These pests feed and lay eggs in cotton plants. Courtesy of
Wellcome Images.

5. Cross section of a cat's tongue. Courtesy of Wellcome Images.

Wellcome Images.

6. Coronal -- or frontal view -- of a mouse brain. Neurones -- or nerve cells -- are color
coded based on depth. At the top is red followed by orange, yellow, purple, blue and
green. Courtesy of Wellcome Images.
Dendritic tree -- branched projections of neurons -- in the cerebellar cortex of a rat brain.
"The cerebellar cortex forms part of the cerebellum, the region of the brain which plays a
role in controlling accuracy and coordination of movement." Courtesy of Wellcome
Images.

7. Metabolites inside a mouse kidney. Amino acids aspartate and glutamine are red and blue
while the antioxidant glutathione is seen as green in this image. The "resulting image
shows how metabolism varies between cells in a single organ. The higher the
concentration of the molecule within the cell, the brighter that colour appears." Courtesy
of Wellcome Images.
An astrocyte cell -- a gilal, or non-neuronal cell -- in the brain taking up a carbon
nanotube, which could be used asa drug delivery system. The cell is green while the
nanotube is brown in this image. Courtesy of Wellcome Images.

8. A paraitoid wasp, Wallaceaphytis kikiae, which helps out farmers around the world. "Its
close relatives in the genus Aphytis successfully control populations of scale insects
(sap-sucking agricultural pests), which attack oranges and other citrus fruits around the
world. The female wasps lay their eggs in the scale insects which are then killed by the
wasp larvae." Courtesy of Wellcome Images.

9. View of a healthy adult, living human brain. The front of head is toward the left of the
image and a MRI was used to collect information on the "pathways of white matter in the
brain." Courtesy of Wellcome Images..

11. Mouse lungs filled with microparticles carrying drugs (the red/pink spots). ". Current
anti-cancer therapies have many toxic side effects so research into other ways of
delivering drugs to specific areas of the body are being investigated in order to decrease
these unwanted side effects. Here, microparticles were delivered to the lungs using a
route similar to drugs administered by an inhaler." Courtesy of Wellcome Images.
