Understanding inheritance patterns in Genetics Although many things about heredity and genetics have been known since prehistoric times, it wasn't until Gregor Mendel began his genetics experiments in the mid 19th century that modern genetics came to be.Through his studies, Mendel was able to...
Virology: What is antigenic shift?
By: Joshua Horn - 257112
The influenza virus is well-known for its fast mutation rates, which frustrate scientists who develop vaccines and treatments. While these viruses have fast mutation rates, one of the most rapid and dangerous transformations happen in the form of something called antigenic shift. Antigenic shift occurs...
The benefits of embryonic stem cell research
By: Elaine Sihera
Stem cells are very useful for two main reasons: they easily replicate themselves and they can grow into any kind of body cells required, whether for organs, muscles or bones, etc. Embryonic stem cells are extracted from unformed embryos (blastocysts) either already in the womb...
Understanding inheritance patterns in genetics
By: Jennifer Allsbrook
Variation, genetic differences essential to the survival of a species, are passed on from parent to offspring, generation to generation. Genetics, the study of this inheritance, is an expanding and ever-changing branch of science. New discoveries are being made daily as our knowledge and understanding...
Should Smokers and the Obese be Denied Coronary Artery Bypass Surgery
By: Georgia Stewart
If smokers and the obese are denied coronary artery bypass or other medical procedures where will this type of discriminatory screening end? Smoking and overeating are not the only life-style habits that people adopt that are potentially dangerous. There are those who participate in...

Genetics most definitely appears to determine human intelligence, along with your environment and your generalized health. Recently, scientists have discovered that intelligence is strongly related to the brain's axons. These axons are part of the wiring of the brain which sends signals throughout the...
Pros and cons of Lap-band surgery
By: Vea Terrie
Since the first laparoscopic adjustable bands for weight loss were used on patients in Europe and Australia in 1993, lap-band surgery has grown in scope and popularity. Lap-band surgery was initially used only to treat morbidly obese patients, however, it is currently made available to...

There is no question that embryonic stem cell research is one of the most controversial issues of our time, because it deals with the fundamental precepts of life itself. Is a human embryo a life, a human being, or the incipient form of a life...
Understanding inheritance patterns in genetics
By: Amanda Mittra
"A chip of the old block", and "Like father, like son" are some of the age old adages that reflect man's understanding of resemblances in families, especially between parents and children. There has always been a general acceptance that "like begets like". Interestingly much...
