Don’t smite the biter that feeds you. Like all organisms on earth, mosquitoes have an important role for balance in many ecosystems. Although for humans they have proved the second most lethal creature on the planet for humankind, (the first of course being human...
World first: How scientists have created artificial life
By: Lane Weinberg
I had read an article about this subject some time agoand was highly impressed with the researchers behind this ‘discovery’, particularly lead biologist J. Craig Venter. He is the president of you guessed it, The Venter Institute, which has four branches: The Center for...

Most people think of ice and snow when they think of penguins, but most penguins do not live on the Antarctic continent and many seldom see either ice or snow. Their home is in the vast Southern Ocean, and they breed on the sub-Antarctic islands...

Bacterial artificial chromosome (BAC) is a major breakthrough in genomic studies as it facilitates genetic sequencing of larger genomes, such as the human genome, in comparatively less time at a much lesser cost. Mechanism of genetic cloning: Genetic sequencing is the process in which DNA...
