Legionella pneumophila (TEM)

Legionella pneumophila, the causative agent of legionnaires' disease. Legionella pneumophila was first identified as an agent of disease after after a mysterious outbreak of pneumonia caused 29 deaths at an American Legion convention in 1976. The bacteria was found living in watertanks, showerheads and air-conditioning systems. The disease, also called legionellosis, often causes fatal pneumonic lung damage in the elderly and weak.

Narrowed Artery (atheroma)

Light micrograph illustrates a transverse section of an artery exhibiting partial obstruction due to the presence of an atheroma (depicted in light pink at the bottom). Atheroma refers to the accumulation of lipid-rich materials within the arterial wall, which can significantly diminish the lumen's diameter (the inner space shown in white). This narrowing impedes adequate blood flow, resulting in ischemia to the tissues that depend on that arterial supply. In cases where the arteries supplying the heart become completely occluded, this condition may lead to a myocardial infarction, commonly known as a heart attack.

Fruit Fly Mutant

Scanning electron micrograph of an "ectopic eye" mutant of Drosophila melanogaster, also known as the vinegar fly or fruit fly. In this mutant, the eyes grow on different parts of the body (in this image on the antennae). A "switch for the eye" was built into the animal at various chromosome regions by gene manipulation.

Description: Poison Ocellate Octopus on blue fabric, TK3 dive site, Lembeh Straits, Sulawesi, Indonesia

The Poison Ocellate Octopus, also known as the Blue-Ringed Octopus, is a small but fascinating creature found in the waters of the Pacific and Indian Oceans. What makes it truly remarkable is its striking, bright blue rings, which serve as a warning sign to potential predators. These rings are a visual cue to stay away, as this octopus carries a potent neurotoxin that can be lethal to humans and other animals

Plant Root with an Ectomycorrhiza Layer

Scanning electron micrograph of a plant root with an ectomycorrhiza layer (white). By freeze-fracture preparation, cells (brown) and fungal hyphae (white) are clearly distinguishable. Phenol droplets can be seen in the plant cells. Mycorrhiza is the symbiotic association of a root with fungi. The mycorrhizal fungi provide nutrients and water to the plant and in turn receive some of the assimilates produced by the photosynthesis of the (green) plants. The mycorrhizal fungi have a much greater ability to obtain minerals and water from the soil than plants. Often the water, nitrogen and phosphate supply of the plants is improved. Furthermore, mycorrhization offers some protection against root pathogens and above-ground pests, such as aphids or harmful fungal infections. In addition, it also increases the dry resistance of plants, which can be particularly beneficial in extreme locations.

Cell Division / Mitosis⁠

Fluorescence light micrograph of human cells showing the stages of cell division starting with interphase (at top). Progressing downwards, the stages shown are: prophase; metaphase, with chromosomes all attached and aligned; anaphase, with chromosome separation; and telophase, with the formation of midbody and cells beginning to flatten.⁠

National Ignition Facility Achieves Fusion Ignition

Computer artwork showing the target (sphere, center) inside the target chamber of the National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory, California, USA. This site has achieved ignition of a fusion reaction which is one of major hurdles to creating a sustainable fusion energy source.

On Dec. 5, 2022 a team at the Lawrence Livermore National Laboratory's "National Ignition Facility" (NIF) conducted the first controlled fusion experiment in history to reach this milestone, also known as scientific energy breakeven, meaning it produced more energy from fusion than the laser energy used to drive it.

Scanning electron microscope image of cells from a sickle cell anaemia (SCA) patient. This inherited condition results in an abnormality in the oxygen-carrying protein hemoglobin found in red blood cells. The difference in the protein leads to a rigid, sickle-like shape of the red blood cells under certain circumstances and the deformed cells may block capillaries. An attack can be set off by temperature changes, stress, dehydration, and high altitude. A person with a single abnormal chromosome copy for SCA does not usually have symptoms and is said to have sickle cell trait. Sickle cell anemia is particularly common in areas with malaria, since those affected are protected from the severe course of malaria disease.

Inadequate hand washing.

Woman's hands holding a child's hands photographed in UV light after application of a special revealing fluid and subsequent hand washing. The fluid fluoresces under the UV light to reveal the areas that have not been washed effectively (light areas). This illustrates the importance of thorough hand washing to remove bacteria and prevent the harmful effects of cross-contamination.

Chlamydia Bacteria in a Cell

Transmission electron micrograph (TEM) of Chlamydia pneumoniae bacteria inside a lung cell. The white area at center is an inclusion body containing bacteria (yellow/brown) at different stages in their life cycle. Chlamydia species bacteria are unusual in that they are obligate intracellular parasites, living and reproducing only inside cells. Human infection with C. pneumoniae is common and most often asymptomatic. However, it can cause community-acquired pneumonia and laryngitis. Infection with C. pneumoniae has been shown to be a risk factor for developing atherosclerosis (fatty plaques) in blood vessels.
