Explanations of the cytoskeleton of living cells
By: Tami Port MS
The cytoskeleton is a network of protein fibers that acts as a kind of scaffolding, giving shape and protection to both prokaryotic and eukaryotic biological cells. However this minute network does much more than keep the cell in its proper shape. * Cytoskeleton in Motion...
Book reviews: Dogs: Their Fossil Relatives and Evolutionary History, by Xiaoming Wang and Richard Tedford
By: Tami Port MS
Paleontologists Xiaoming Wang and Richard Tedford wrote the book (literally and figuratively) on the evolution of the taxonomic family Canidae; an evolutionary history that spans 40 million years. The taxon is comprised of dog-like creatures that range from the extinct, ancient Hesperocyons to today's more...

By: Kate Johns
Fish swim in schools because they were told to do so by their mothers for their own safety. It's very similar to human teenagers walking in an amusement park together, when a Mother says, "Stay with the group when you go to the amusement park...
Advantages and disadvantages of genetic engineering
By: Izra Jute

Deoxyribonucleic acid, otherwise known as DNA, is responsible for the genetic characteristics for every living organism. It can influence the individual's physical appearance, actions...
Do you think genetic altering is right or wrong?

Gene Deep Beauty:Breast augmentation, liposuction, face-lifts and nose jobs have become so commonplace that the procedures have long ceased to create any questions or controversy. The old familiar adage claims, "Beauty is in the eye of the beholder," yet the perception of beauty is...
Do you think genetic altering is right or wrong?
By: Steven Cuthill
Cloning of embryos brought us Dolly the Sheep and other animals including cows, pigs and cats have been cloned. That is one side of the story in the development of scientific techniques to advance understanding in embryos and cloning. Legislation in the UK has changed...
What you should know about edible microbes
By: Jennifer Allsbrook
