Because they can divide to become almost every other kind of body cell, human embryonic stem cells may hold the key to seemingly miraculous cures. They may be able to create new, healthy pancreatic islets which can once again produce natural insulin for diabetics. They...
An overview on behavioral genetics
By: Wendy R.
Trying to define behavioral genetics can be difficult. In simple terms, it is the study of genetics in relation to the outward behavior of an organism that is seen. So in other words, it is the study of the hereditary factors of behavior. Included...

The promise of embryonic stem cells in curing diseases is their ability to differentiate into almost every other kind of body cell. The medical hope is that human embryonic stem cells can do the same in adult human beings, and thereby create healthy cells to...

Although it has long been known that genetic errors such as Down's syndrome and phenylketonuria often impact negatively on intelligence as well, the extent to which normal genes play a role in determining human intelligence is much less clear. To determine what, if any, role...
A look at how scientists can use embryonic stem cells to cure diseases
By: Elaine Sihera
In November 2008, history was made in Spain when scientists announced the "world's first tissue-engineered whole organ transplant using a windpipe made with the patient's own stem cells". Since then scientists all over the world have been quietly trying to emulate that achievement. Right now...

Sperm and egg unite; it is the symbiosis of a new life, the beginning of a new being. Paternal and maternal progenitor beings have each contributed a blueprint containing one half of their own genetic recipe. In the case of humans, 23 chromosomes each will...

In every workplace, a set of standard safety issues exists and a set of specialized safety issues exists. In a Fuels operation, the standard industrial safety issues apply, and the specialized issues of transfer, storage, testing, and movement around highly volatile fuel and it's more...
A look at how scientists can use embryonic stem cells to cure diseases
By: S. Shelton
Embryonic stem cells have amazing qualities. Created only days after an egg and sperm have come together, these few cells become the many that form the human body. Two unique characteristics (their capacity to continuously grow and divide, and their ability to become any cell...
How does bacteria become resistant to antibiotics?
By: Nadine Riggs
Bacteria and How They Become Resistant to Antibiotics Bacteria are small one celled organisms that live naturally in soil, water, plants, and animals. Most bacteria are harmless as they are naturally occurring on the human body. Our skin is covered with a normal level of...
Bone grafts explained
By: Paul Simms
A bone graft is the insertion of a material at the site of bone loss in order to stimulate bone growth. In most situations, the material that is inserted in the site is bone tissue, and usually it comes from another area on the patient's...
