A ball and stick model of Human Insulin. Isolated on black.

Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).

Science background with molecule or atom

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Backgrounds of Bacteria and Mold under the microscope in Lab.

Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.

Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway. Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.

PETase is a bacterial enzyme that breaks down PET-plastic to monomeric molecules. The whole bacterial degradation process yields terephtalic acid and ethylene glycol, which are environmentally harmless.

Close-up shot of a petri dish for checking an antibiotic in the laboratory.

The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor has a strong effect on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

A molecular model of Bisphenol A or BPA. It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses. Isolated on white.

Microscopic photo of a thin section of calcareous tufa of Holocene age.

Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
