Photosynthesis is the method of plants to gain energy transforming light into bonds of sugar. Sunlight's cardinal function is to affect every organism by providing sufficient amount of energy; every food and fossil fuel we consume is a product of photosynthesis, the process that transforms...

Bioengineering is defined as an interdisciplinary field that integrates engineering principles with physical sciences, chemical sciences, mathematical sciences, computational sciences and applies them to solve problems in biology, medicine, and health care.The mainstream bioengineering research areas are Biomaterials, Biomechanics, Bioimaging and Bioinstrumentation. New bioengineering...

Proteins are composed of amino acids (20 different types) joined by peptide bonds, forming polypeptide chains. Proteins are essential elements in the make up of cells, used as signals, for structure, as hormones, and enzymes are made up of proteins, which carry out metabolic pathways...

Stem cells are microscopic cellular bodies which have spurred a political and religious debate worldwide. There are few sides but many reasons for and against stem cell research. But in order to have a standpoint on stem cells, one must have a basic understanding of...

There's a place where past, present and future meet. "Where is it" ? Look for it in the inner space of the cell. There, at a stop along the way on the human life cycle, time and destiny are breached and turn back, as mature skin...
What is cloned beef?
By: Heather Youngs
This month (May 2008), the FDA approved the cloned beef for human consumption. The technology, developed by companies such as Viagen (Australia) and SEK genetics (USA) was developed in 2003 and has been used for breeding show animals. Although there was a voluntary moratorium on...

Cytoskeletal proteins make up the cytoskeleton of a cell, which is the basic structural framework providing the cell a shape and providing internal transport pathways, aiding in cell division, and performing functional tasks, such as motion. The cytoskeleton is traditionally thought to occur only in...
How photosynthesis works
By: Wilhelm Schnotz
Photosynthesis: A process essential for life on earthPhotosynthesis is the most essential biological process for human and animal life. It is the process by which carbon dioxide and water are converted by plants and sunlight into the oxygen we breathe and the organic molecules (like...
Functions of membrane proteins
By: Debbie Luyo
Biological membranes encircle eukaryotic cells and their components, or organelles. Membranes allow selective permeability to the cell or organelle, and prevent spontaneous diffusion of water and other molecules. Thanks to the surrounding membrane, idyllic conditions, such as pH and ionic strength, can be maintained within...
The development of the cell: Conditional specification and autonomous specification
By: Eric Yager
Stem cells have received a great deal of public attention over the past few years due both to their interesting biological characteristics and their therapeutic potential. What makes stem cells unique over other cells found in the human body is that they are capable of...
