A Wizard of Oz Moment for Black and White Images

In a Wizard of Oz moment, artists are bringing full color to black and white images, while chronicling the past in a never before seen way.  Beyond their aesthetic appeal, colorized images play an important role in education.  The famous image of Pavlov with his dogs is recognizable to many but not everyone notices all the tools involved in his findings. Digital coloring highlights these areas, helping students understand how Pavlov made his important discoveries in psychology. In scientific images, digital color can locate everything from stars to microbes in the grayscale of SEMs and old photos, making them perfect for textbooks and other publications. Stock Gallery of Colorized Images Colorized images also have a historic significance. Black and white photographs may depict an event in the past but fail to capture the full appearance of an era. Historians have recently discovered that many sculptures from ancient Greece were painted. Now artists can reintroduce this color, revealin…

The Fascinating Journey of Blood Through Your Body

Did you know that your body houses millions of vessels that are circulating blood at this very moment? In fact, if all the blood vessels in the average adult were connected in one line from beginning to end, they would stretch 100,000 miles. The circulatory (or cardiovascular) system carries blood all throughout your body to transport nutrients, allow for essential body functions like breathing, and maintain an overall homeostasis. Arteries, veins, and capillaries are the three different types of blood vessels that make blood circulation possible. Veins transport deoxygenated or waste-rich blood that will eventually be filtered, and arteries carry the filtered, oxygenated blood. Capillaries are the middleman of blood circulation, as they enable the exchange of blood between arteries and veins. Stock Video of Blood Flow and Circulatory Anatomy
There are two types of blood circulation: pulmonary and systemic. Pulmonary circulation is the transportation of blood to the lungs so that the …

The Beauty of Illustration in an Age of Photography

You may associate nature and medical illustration with dusty old tomes, but it's more relevant and beautiful than ever. In a world that's getting more complicated and where technical knowledge can make or break careers, precise and informative illustration is more critical than ever.Stock Images of Nature & Medical Illustration Illustration can show the unseen and explain the unclear. Think about a photograph of internal human anatomy. Even if it is a high resolution, super sharp image, it may still be difficult to decipher. A science or medical illustration, on the other hand, can show each anatomical part in a different color, label it, and indicate its function. Unimportant details can be left out and critical information highlighted.
In many cases, a photograph can't display the same level of detail as a well-designed illustration. Volcanos are spectacular on the outside but their inner workings are hidden from view without a well-placed cross-section. Illustratio…

Wild Weather & Climate Change

As levels of CO2 in the atmosphere rise from man-made emissions, the likelihood of extreme weather is increasing. Over recent decades, scientists have seen a trend of increased storm activity along with higher temperatures.
Stock Images & Stock Video of Wild Weather
Drought, flooding, deadly hurricanes, and tornadoes are now more common around the world. Along with loss of life and property, animals are also struggling to survive.

Hurricanes, also called typhoons or cyclones, form near the equator, over warm ocean water. As the water evaporates, it creates clouds that rise, allowing cooler air to swirl in beneath them.   

As the ascending air cools, it descends, creating moving air masses.  The earth's rotation moves them, making the system spin faster.  Eventually, the air speeds up and an area of calm air forms in the center, called the eye of the hurricane.

The system continues to move over warm water, picking up more evaporated water and growing stronger.

Phytoplankton & CO2

One group of creatures produces 70% of the earth's oxygen and also consumes carbon dioxide at an amazing rate. They are phytoplankton, and most are tiny single-celled organisms. Phytoplankton come in many shapes and forms. The majority are single-celled plants, but some are bacteria and others are protists. Common types of phytoplankton are cyanobacteria, green algae, diatoms, dinoflagellates, and coccolithophores. Phytoplankton plays an important role in human life in that they produce 70% of the oxygen we breathe. A much greater amount than terrestrial plants. They are part of the carbon cycle, as they consume atmospheric carbon dioxide (CO2). CO2 resides naturally in the atmosphere, but human beings, mostly through the burning of fossil fuels, have released ever greater amounts into the atmosphere. Stock Images and Stock Video of Phytoplankton Along with CO2, phytoplankton need sunlight and other nutrients to survive. At certain times, phytoplankton grow at an explosive rate ov…

Fun With Chemistry

One of the more fun classes in high school was chemistry lab, especially on the days when you made things explode or catch fire...on purpose. Relive those good old days with our videos of exploding chemistry experiments.Stock Videos of Exploding Chemical Reactions The Barking Dog experiment and the Rainbow Clock were very popular. But it's hard to beat the surprisingly loud explosion of a nitrogen triiodide explosion when it's touched lightly by a feather.  And no one expects a tiny piece of metal dropped into water to steam, hiss, dance about and eventually explode, but lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and caesium (Cs) do exactly that.
Gifts for the Chemistry Geeks
Here's what happens in each reaction: Let's check what happens if we would drop a pea-size piece of metal in water.Lithium just sizzles on top of the water, but doesn't explode.Sodium floats on top of the water, then ignites with a yellow-orange flame and also doesn't explode…
