Three dimensional structure of the Ebola virus
The causative agent of viral hemorrhagic fever in humans and a potential biological weapon, Ebola virus is presented here in beautiful, three dimensional form.
The Ebola-encoded structures are shown in maroon, while human cells are shown in grey. This model was based on 20 years of virology data, X-ray analysis, and computation biology techniques.

Inside the human heart
National Geographic have an impressive gallery showcasing one of the most beautiful, complex and important organs of the human anatomy: the heart.
From NG:
Tissue-paper thin but tough, the valves of the human heart open and close to pump 6 quarts (0.9 liters) of blood a day through 60,000 miles (97,000 kilometers) of vessels. That’s equivalent to 20 treks across the United States from coast to coast. The heart is a magnificent machine when it’s in good working order. But coronary heart disease is the number one killer of American men as well as women, resulting in 500,000 deaths in the United States and killing 7.2 million people worldwide each year.

Jupiter: Moons
The planet Jupiter’s four largest moons are called the Galilean satellites, after Italian astronomer Galileo Galilei, who observed them in 1610. The German astronomer Simon Marius claimed to have seen the moons around the same time, but he did not publish his observations and so Galileo is given the credit for their discovery. These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds.

The Art in Biomedical Research
1. Muscle Stem Cell Factories

This micrograph shows cells called myoblasts attached to spherical microcarriers, which allow the growth of adult stem cells that have been isolated from skeletal muscle. The stem cells are shown in green. By combining these cells in a bioreactor, the muscle stem cells can be greatly increased in number and then separated from the myoblast “feeder” cells. The image was produced in the course of studies aimed at creating artificial “stem cell factories” and was supported by NIH funding from the National Heart, Lung and Blood Institute.
2. Scaffold for Cartilage Regeneration

Due to a lack of blood vessels and other characteristics, cartilage heals very slowly. One way to accelerate natural cartilage repair and growth is to use tissue engineering, or the artificially-stimulated production of functional replacement tissue. The image shows a three-dimensionally woven biomaterial scaffold. The scaffold consists of multiple layers of resorbable fiber bundles that have been woven into a porous structure. The scaffold is then seeded with cells that grow to become new tissue as the fibers are resorbed. The fibers provide stiffness and strength in a manner that mimics native collagenous tissues such as cartilage. This work to use tissue engineering to generate replacement cartilage is supported by NIH funding from the National Institutes of Arthritis and Musculoskeletal and Skin Diseases.
3. Production of New Neurons

New neurons are produced from neural stem cells in several areas of the adult brain. One such area is in the hippocampus, a brain structure crucial for cognitive function. The number of neural stem cells in the hippocampus decreases over time, possibly contributing to the cognitive impairment associated with aging. When activated by extrinsic stimuli, stem cells divide and generate progenitor cells, which eventually mature into neurons and migrate into the layers above, whereas stem cells themselves undergo additional rounds of rapid divisions and convert into astrocytes, thus leaving the stem cell pool. The image depicts stem cells (green) and neuronal nuclei (red). This research to understand how the brain produces new neurons is supported by NIH through the National Institute of Mental Health and the National Institute of Aging.
4. Brain, Heart, and Lung Communication

Both glutamate and nitric oxide play an important role in transmitting cardiovascular and respiratory signals between the brain, heart, and lung. This butterfly shaped figure is an image of a rat spinal cord showing the distribution of three types of glutamate and nitric oxide synthesizing enzymes. Understanding the action and interaction of glutamate and nitric oxide in the nervous system could lead to better treatments for cardiovascular diseases such as hypertension and heart failure. This work is supported by NIH funding from the National Heart, Lung and Blood Institute.
