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.
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.
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.
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.
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.
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.
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.
Want to learn about microbes? Fun and safe experiment for growing fungi and bacteria using home made potato sucrose gel (recipe included).
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.
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.
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.
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.
This article looks at the basic similarities and differences between animal and plant cells, and the functions of different organelles, and how cells are adapted to perform certain functions.
Chemosynthetic bacteria are organisms whose primary source of energy comes from the chemical reactions of inorganic molecules.
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.
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.
