One Hundred Years of the Flu

100 years ago one of the deadliest natural disasters hit humanity, killing approximately 4 percent of the earth's population. Even people in remote Pacific Islands and the Arctic met their demise due to this virus. This shocking number of deaths was caused by the flu, although these days most healthy people take the flu lightly. That particular strain, the H1N1 influenza virus, commonly known as the Spanish Flu, claimed many young as well as many previously healthy adults. Additionally, since it arrived on the heels of the Great War, many people were malnourished, living in overcrowded medical camps with little access to good hygiene. Royalty Free and Rights Managed Stock Images of the Flu Government censorship may have played a role in the pandemic. To appear strong, many governments didn't reveal how devastating the flu was, giving no warning to the public to protect themselves. In Spain this information was not censored, giving the world the false impression that the Spani…

The Quirky Beginning of Biomedical Research, with Royalty Free Images

Few of us give a second thought to popping an aspirin or any other over-the-counter painkiller for a minor ache or pain. Yet, this simple act wouldn’t be possible without the field of biomedical research. Every parent can breathe easier knowing that there are vaccines against measles, whooping cough, polio, chickenpox, mumps, tetanus, and many other childhood diseases. Our modern world also affords us medication to help control diabetes, high blood pressure, high cholesterol, and other life-threatening conditions.Royalty Free Images of Biomedical Research Part of any thorough research method is the clinical trial or the testing of a medication, vaccine or health recommendation. Clinical trials have a quirky history. The first recorded instance of a clinical trial took place in 562 BC. King Nebuchadnezzar, who was not a scientist, wanted his people in top physical condition. He ordered them to consume only meat and wine, believing these to be the most nutritious foods. Several vegeta…

3D Molecular Models

Dive into chemistry with 3d molecular models! See how the basic building blocks of matter form to create everything in the known universe. Need a refresher on chemistry? An element is a single atom characterized by the number of protons in its nucleus. Atoms bind together to form molecules, which can either be a series of the same element or different elements, making it a compound. A molecule can be a simple pairing of one element, such as the oxygen in the air (O2) or a complex chemical compound, such as ethanol (CH5OH) or baking soda (NaHCO3), containing many different elements.Stock Image Gallery of Molecular Models and Video 3d illustrators represent molecules in a variety of ways. There’s the classic ball and stick model, ribbon models, and the intricate hydrophobicity surface model.
CPK coloring is the most common color system for models (white for hydrogen, black for carbon, red for oxygen, etc.), but artists use a variety of different color pallets to bring uniqueness to th…

Acute Flaccid Myelitis, a Growing Concern for Parents

Flu season is here, but parents have a new condition to be worried about for their kids: Acute Flaccid Myelitis, or AFM. It has been making headlines as alarming numbers of children are being paralyzed in a pattern that resembles polio scares in the past.AFM has been in existence for a long time, but the recent rise in cases is what’s signaling danger. Polio was eradicated in the United States in 1979, however, at this point in time, there is no such future hope for AFM. This dreaded condition has several possible causes including viruses, environmental toxins, and genetic disorders. Symptoms often follow an infection and high fever. The suspected viruses that may cause AFM include poliovirus or non-polio enteroviruses, West Nile Virus and adenoviruses. RF Images & RM Images of Acute Flaccid Myelitis Although adults may contract this condition, most cases are in those under 18 years old. Symptoms parents should look out for include the sudden onset of drooping eyelids, difficulty mo…

The Beautiful Creepy Crawly World of Francesco Tomasinelli

Biologist and photographer Francesco Tomasinelli is willing to go where few others are: damp caves where the floors, walls and ceilings are crawling with living creatures. Once there, he pauses to take beautiful and unusual photographs. He has captured giant cockroaches eating a dead bat, a snail slowly attacking a moth, and walls blanketed with crawling insects. Needless to say, the subjects of his images include endless numbers of spiders, scorpions, centipedes, and all manner of creatures that are the stuff of nightmares. View Stock Images of Tomasinelli’s Nature Photography Tomasinelli says, “We are not used to considering small insects and specialized spiders that live in caves as noteworthy animals. But in recent years it has been discovered that these organisms can give us valuable indications to better understand the effects of climate change on ecosystems.” He was involved in a project called CAVELAB and has photographed in caves in Italy and Borneo.

Explore the Human Microbiome

The idea of bacteria creeping through your body might be less than appetizing. We often associate the presence of bacteria in our bodies (especially in our digestive system) with infections, viruses, and food poisonings. However, scientific findings have uncovered the fact that there are also many types of good bacteria that are essential to our health. This collection of good and bad bacteria within our bodies have also been discovered to be strikingly diverse from person to person. The definition of the human microbiome is still somewhat ambiguous and disputed but is commonly known to be the vast ecosystem of microscopic organisms (microbes) living within us. According to the National Center for Biotechnology Information (NCBI), we consist of 10-100 trillion microbiota, also known as microbial cells. These cells hold genes that determine cell behavior.Stock Images and Stock Video of Microbes
Scientists have become specifically interested in the gut (our stomach and intestines) as a…

The Natural History Collection

Science Source is pleased to announce it is now offering the Natural History Museum of London’s Collection online!

They'll Hijack Your Body to Replicate Themselves

Zombies? Science Fiction? Fantasy? No, it’s the very real flu virus, cold virus, rabies, HIV, ebola or any other viruses. Viruses are microscopic nonliving organisms that can only reproduce by hijacking the production mechanism inside a living host’s cells. The virus replicates itself until the cell bursts, spreading the virus further. This usually means death to each cell that becomes infected. If the host’s immune system cannot destroy the virus, ultimately it can mean a very bad outcome for the host as well. They differ from bacteria in that bacteria are alive, reproduce through fission (splitting apart) and carry on metabolic functions such as digestion.Stock Images of Bacteria and Viruses Viruses cannot reproduce on their own. They need to attach themselves to a host’s cells and inject it with their DNA/RNA, taking over the cell’s “machinery” to manufacture and reproduce. This continues until the cell literally bursts. The new viruses go on the hunt for more cells to continue th…

The Aliens are Here: Invasive Species

Exotic beauty hides a deadly beast.  The lionfish is but one of over 4,000 invasive species found in the United States doing damage to wildlife, plants, our economy, and our health. An invasive species, also called alien species, is a non-native plant or animal that may have no natural enemies and possibly possess other advantages that allow it to propagate to such a degree that it causes damage.  This may include the killing of already endangered plants, habitat loss, damaging crops, clogging pipes in power plants or otherwise wreaking havoc.  Their success makes them impossible to eradicate and very difficult to control. One example, the lionfish, is of great concern in the Southern United States, killing off 65% of the local fish population within two years. Some of these prey fish are critical for cleaning the coral, so the coral reefs are also dying off.Stock Images of Invasive Animals & Plants It's believed this invasion was caused by a few pet lionfish owners releasing…

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 …
