Bacteria have some amazing abilities. They can live in extreme habitats, produce light, communicate with each other, and act as predators and magnets.
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.
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.
While both cause infection and disease, viruses and bacteria are entirely different! Read all about them and more here.
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.
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.
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.
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.
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.
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.
Want to learn about microbes? Fun and safe experiment for growing fungi and bacteria using home made potato sucrose gel (recipe included).
Chemosynthetic bacteria are organisms whose primary source of energy comes from the chemical reactions of inorganic molecules.
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.
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.
