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.

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.

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.

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.

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.

Guide to the different tests you can perform on unknown bacteria to identify it. These methods are really important in many fields when you are faced with an unknown sickness or contamination.

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.

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.

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.

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.

Bacteria have some amazing abilities. They can live in extreme habitats, produce light, communicate with each other, and act as predators and magnets.

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.

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.

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.

An amoeba is a one-celled creature with interesting features. Amoeboid organisms live in the environment and in our body. Some are harmless, but others cause disease.

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.
