What are aquaporins and how do they work?
By: Melody Clearwater
Water is the most essential molecule of life. Because of water’s physical properties, living organisms depend on it to survive. Water’s neutral pH and polarity make it a universal solvent for many of the solutes that life depends on, such as essential ions...
Wet mount microscope slide preparation of eukaryotic cells
By: Tami Port MS
In order to view small objects with a compound microscope, the object, or specimen to be viewed must be properly prepared, mounted on a slide, and sometimes stained to increase the contrast between the object and background. This technique is used for preparing eukaryotic cells...

Central Nervous System, neurons and nerve impulses; all are familiar yet almost mystical words because many of us understand so little about this fundamental process producing human awareness. Human awareness occurs in incremental stages starting with the peripheral nervous system’s sensory input, delivered via...
World first: How scientists have created artificial life
By: Lane Weinberg
I had read an article about this subject some time agoand was highly impressed with the researchers behind this ‘discovery’, particularly lead biologist J. Craig Venter. He is the president of you guessed it, The Venter Institute, which has four branches: The Center for...

Cells are the basic structures of all true life forms. If it is alive, it has cells. The first life forms were single cells. They evolved billions of years ago and existed for billions of years before multicellular life evolved. All multicellular life forms have...
Understanding cell division

A Reduction Division How does an organism with diploid body cells produce haploid gametes? MEIOSIS: A process of cellular division in which the number of chromosomes is reduced by half is responsible for these. This change occurs through a process called meiosis, the type of...

In order to identify the types and causes of inclusion bodies in human cells, it's first important to know what an inclusion body is. In simple terms, for these formations are anything but simple, inclusion bodies are abnormal structures that appear in cells. They're typically...
Types of pigment granules that accumulate in the cytoplasm of human cells
By: Alicia M Prater PhD
Pigment granules accumulate in human cells for various reasons. The granules may be stored in the organelles that produce and/or transport them, or they may be cytoplasmic inclusion bodies that result from aging or disease. Organelles are found in the cytoplasm of the cell, as...

Euglenas are single celled microorganisms that exist in the class of flagellates that are commonly found in fresh water. As of today there are over 1,000 different species of euglena and many more are waiting to be discovered and named. Several of the species...

Researchers at the Howard Hughes Medical Institute have pioneered an imaging technique which renders living cells in 3D via a system of 'light sheets' according to reports in Nature Methods. The light sheets consist of a technique called plane illumination, in which light is shone...
