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

The Natural History Collection

Science Source is pleased to announce it is now offering the Natural History Museum of London’s Collection online! Completed in 1881, the Museum of Natural History in London, was one of the first museums designed for the public. Unlike its predecessors, it no longer required an application for entry and offered labels on everything on display.The Natural History Stock Image Gallery Today the Museum remains a center for culture and education in London. Its permanent collection contains some 80 million objects, including fossils, rocks, minerals, insects and taxidermy animals. With multiple education programs, such as the famous “How Science Works” program, which offers hands-on workshops with microfossils, the museum is an ideal location for science enthusiasts of all ages and abilities. Fossil note books, mugs, and more! Explore the collection’s many photographs of skeletons, bird eggs, and fossils, illustrations of prehistoric creatures and much more!
