Blood Groups, Blood Typing and Blood Transfusions
The discovery of blood groups
Experiments with blood transfusions, the transfer of blood or blood components into a person’s blood stream, have been carried out for hundreds of years. Many patients have died and it was not until 1901, when the Austrian Karl Landsteiner discovered human blood groups, that blood transfusions became safer.Mixing blood from two individuals can lead to blood clumping or agglutination. The clumped red cells can crack and cause toxic reactions. This can have fatal consequences. Karl Landsteiner discovered that blood clumping was an immunological reaction which occurs when the receiver of a blood transfusion has antibodies against the donor blood cells.
Karl Landsteiner’s work made it possible to determine blood groups and thus paved the way for blood transfusions to be carried out safely. For this discovery he was awarded the Nobel Prize in Physiology or Medicine in 1930.
What is blood made up of?
An adult human has about 4–6 liters of blood circulating in the body. Among other things, blood transports oxygen to various parts of the body.Blood consists of several types of cells floating around in a fluid called plasma.
The red blood cells contain hemoglobin, a protein that binds oxygen. Red blood cells transport oxygen to, and remove carbon dioxide from, the body tissues.
The white blood cells fight infection.The platelets help the blood to clot, if you get a wound for example.
The plasma contains salts and various kinds of proteins.
What are the different blood groups?
The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.There are more than 20 genetically determined blood group systems known today, but the AB0 and Rh systems are the most important ones used for blood transfusions. Not all blood groups are compatible with each other. Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals.
Nobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 and Rh blood groups.
AB0 blood grouping system
According to the AB0 blood group system there are four different kinds of blood groups: A, B, AB or 0 (null). |
Blood group A If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. |
 |
Blood group B If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. |
 |
Blood group AB If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. |
 |
Blood group 0 If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma. |
Rh factor blood grouping system
Blood group notation
According to above blood grouping systems, you can belong to either of following 8 blood groups:| A Rh+ | B Rh+ | AB Rh+ | 0 Rh+ |
| A Rh- | B Rh- | AB Rh- | 0 Rh- |

Genetically Modified Foods or GM Foods
Genetically modified (GM) foods are foods derived from genetically modified organisms. Genetically modified organisms have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change. Other techniques by which humans modify food organisms include selective breeding (plant breeding and animal breeding), and somaclonal variation.
GM foods were first put on the market in the early 1990s. Typically, genetically modified foods are transgenic plant products: soybean, corn, canola, and cotton seed oil. Animal products have also been developed, although as of July 2010 none are currently on the market. In 2006 a pig was controversially engineered to produce omega-3 fatty acids through the expression of a roundworm gene.Researchers have also developed a genetically-modified breed of pigs that are able to absorb plant phosphorus more efficiently, and as a consequence the phosphorus content of their manure is reduced by as much as 60%.
Critics have objected to GM foods on several grounds, including possible safety issues,ecological concerns, and economic concerns raised by the fact that these organisms are subject to intellectual property law.

What is Phycology
Phycology (or algology), a part of botany, is the study of algae. Algae are important as plants in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms that live in a wet environment. They are different from the higher plants by a lack of “normal” roots, stems or leaves. Many types have one cell and are very small or microscopic (including plankton and other algae); many others are have many cells, some of these being very big, like seaweeds such as kelp and Sargassum.
Phycology is also the study of prokaryotic forms known as blue-green algae or cyanobacteria. Some microscopic algae are also in Lichens.
A phycologist is a person who studies phycology.
What is Malacology?
On July - 21 - 2010
Scientists study mollusks to learn how many kinds there are, where they are found, how they came to be as they are, and what their lives are like, as well as many other things about them. These scientists are called malacologists.
