Llamas produce tiny versions of antibodies known as nanobodies. These might be helpful in dealing with the SARS-CoV-2 virus that causes the COVID-19 infection.
Organoids are small and simplified versions of organs that are made from stem cells. They may enable us to create new medical treatments and better understand how organs work.
Tardigrades are strange and very impressive animals that can survive extreme environmental conditions. Recent discoveries have revealed new abilities of the animals.
Autophagy is the removal of damaged or harmful cell components. Lysosomes are vital in this activity. Autophagy is usually helpful but is problematic in some situations.
Bacteria contain structures that perform specific jobs and resemble the organelles found in eukaryotic cells. The organisms are more complex than once realized.
Bacteriophages are viruses that infect bacteria. They don't infect our cells, but they're found in bacteria living in our gut. Here they may affect our lives.
Here is the detail of the experiment exploring the potential of banana peel for use in generating bioelectricity.
Throughout the world there exists numerous viruses and diseases capable of inflicting serious harm (or death) on the human population at large. This article explores the 10 deadliest and most dangerous viruses known to currently exist in the world.
Stentor is an interesting, single-celled predator. At least one species makes relatively complex decisions. Studying it may help scientists understand the behavior of our cells.
Klebsiella pneumoniae is a bacterium that can live in our body and is sometimes dangerous. It's usually harmless in the digestive tract, but this may not always be true.
What causes one person to have clear skin and another person to have severe, cystic acne? Discover the genetics behind the development of this skin condition, in addition to understanding how different treatment options work.
Antibiotics interfere with vital activities in bacteria by various methods. Unfortunately, microbes are becoming resistant to the drugs. Arylomycins may be helpful in this situation.
Immunology is the complex study of the immune system and its associated functions. Immunity is how the body attempts to prevent disease. This article will briefly discuss the types of immunity, vaccines, problems with the immune system, and more.
Staphylococcus epidermidis is a bacterium found on skin and mucous membranes. It's often harmless, but some strains are resistant to multiple antibiotics and may be dangerous.
Social amoebas are also known as cellular slime molds and dictyostelids. They start life as ameboid cells but join to form a multicellular grex or slug when food is scarce.
Planarians are flatworms with an amazing ability to regenerate. Scientists are investigating this ability and hope to apply their discoveries to human biology.
Plasmodium vivax is often said to be a less serious cause of malaria than P. falciparum, but it can be deadly. It may become dormant in the liver and later become active.
Saprolegnia and Phytophthora are water molds. Some species of Saprolegnia kill fish. One species of Phytophthora caused the nineteenth-century potato famine in Ireland.
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.
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.
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 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 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.
One species of bacteria in the genus Yersinia causes bubonic, septicemic, and pneumonic plague. Others cause foodborne illness. One species may eventually help to treat cancer.
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 can cause serious diseases, including CJD.
Bacteria have some amazing abilities. They can live in extreme habitats, produce light or electricity, communicate with each other, and act as predators and magnets.
An amoeba is an interesting one-celled creature. Amoeboid organisms live in the environment and in our body. Some species are harmless, but others cause disease.
A nematode called Onchocerca volvulis causes onchocerciasis (river blindness). Wolbachia may contribute to the disease. Severe itching, skin changes, and vision loss may occur.
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.
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.
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.
Our innate and our acquired immune system contain lymphocytes. The cells play a vital role in fighting infections. NK (natural killer), B, and T cells are lymphocytes.
