Why do cells divide? Are mitosis and cell cycle the same thing? What are the stages of the cell cycle? What are the stages of mitosis? This article answers all these questions.
Antibiotic resistance in bacteria that cause disease is a serious problem. Soil contains many bacteria, some of which may help us by making new antibiotics.
Want to learn about microbes? Fun and safe experiment for growing fungi and bacteria using home made potato sucrose gel (recipe included).
Whether you enjoy hosting fun parties or want a creative way to make your science presentation come to life, here are easy instructions to bake a scrumptious, scientifically-accurate animal cell cake.
Planarians are interesting flatworms with an amazing ability to regenerate. Scientists are investigating the capabilities of the animals in the hope of applying their discoveries to human biology.
Take a closer look at microscopy! Learn the differences between an electron and light microscope, know your resolution from your magnificaiton and learn how to correctly use a microscope.
People worry that deadly viruses like Ebola could turn into airborne forms that could cause a worldwide epidemic. But there are reasons to think it is unlikely.
Bacteria in the genus Yersinia have major effects on our lives. One species causes bubonic, septicemic, and pneumonic plague. Others cause foodborne illness. One may eventually help to treat cancer.
Prions are misfolded proteins that form inside the body or enter the body from the outside. They alter other proteins and cause serious diseases, including CJD.
Bacteria naturally develop resistance to antibiotics, and the unnecessary use of antibiotics in meat production and the treatment of human disease is accelerating this process.
This article is an in-depth review of cells. Meant to help high school and college students gain a better understanding of this chapter of biology.
This article offers an introduction to various members of the kingdom Protista. Colorful photos and videos are included. Designed for students or anyone wanting to learn more.
True plants are currently seen as non-animal organisms that make up the kingdom Plantae. However, there are organisms—like cyanobacteria—that belong to other kingdoms but have plant-like characteristics.
Chemosynthetic bacteria are organisms whose primary source of energy comes from the chemical reactions of inorganic molecules.
Plasmodium vivax is sometimes considered to be a less serious cause of malaria than Plasmodium falciparum. P. vivax can be deadly, however. It becomes dormant in the liver and later becomes active again. The reactivation may cause a relapse, or the return of symptoms.
The world's ecosystems are underpinned by a complex community of single-celled organisms. fundamental to the healthy functioning of both aquatic and terrestrial food webs.
Investigative skills play an important part in learning practical biology. Experiments are important in the scientific method. This article teaches good experimental design for young biologists.
Cancer is an emotive word, but what is it? What causes a normal, somatic cell to turn cancerous? What are our defences against this foe, and are they all useless? Find answers to these questions and some excellent sources to start your own research.
Bacteria have some amazing abilities. They can live in extreme habitats, produce light, communicate with each other, and act as predators and magnets.
Saprolegnia and Phytophthora are important examples of oomycetes or water molds. Some species of Saprolegnia can infect and kill fish. One species of Phytophthora causes late blight in potatoes. This disease was responsible for the devastating nineteenth-century potato famine in Ireland.
This article explains with clear text, illustrations and videos all about diffusion, osmosis, active transport, surface to volume ratio and the temperature and concentration gradients in cell biology.
