The brain and its ever-evolving truths Dr. James Zull‚ professor of biology and biochemistry‚ at Case Western University states‚ "Learning is physical. Learning means the modification‚ growth‚ and pruning of our neurons‚ connections-called synapses‚ and neuronal networks; through experience...we are cultivating our own neuronal

strong back - roughly four times stronger than a human’s when adjusted for size. It is less than 1-foot (0.30 m) long and weighs just 1.7 ounces (48 g). Hero shrews are less flexible than most mammals. Thor’s hero shrew was first described in Biology Letters by a team headed by vertebrate biologist William T. Stanley in July 2013. It was discovered when Stanley dissected a specimen of hero shrew collected in the village of Baleko and found that its spine was different from those of known specimens

topic. Scientists remain divided in their opinions. Some have warned against the hazards of genetic engineering‚ while others have dismissed these perils as inconsequential. Two opposing viewpoints‚ which is right? Lewis Wolpert‚ professor of biology as applied to medicine at University College London‚ says that‚ "There are no ethical issues because you are not doing any harm to anyone." And indeed‚ the gist of his statement is staunchly supported by James Watson‚ a Nobel Prize winner and president

Evolution is a cornerstone of modern biology. It unites all the fields of biology under one theoretical umbrella. Evolution satisfies majority of the

The Importance of Camouflage By Biology 101 May‚ 29 2013 Introduction In life‚ we have heard the phrase “only the strongest will survive”‚ and undoubtedly‚ think of the strength of a lion or the ferociousness of a bear‚ but this is not always the case to being a dominant species in a community. In this lab‚ we will explore the theory of natural selection‚ or as Charles Darwin put it‚ “Survival of the fittest” (King et al‚ 1-14). Through this concept‚ we will come to the understanding

The following elaborates on my motivations for seeking a PhD in the biomedical sciences. If you take a look at the palm of your hand‚ you will notice the striations and ridges‚ formed from epithelial tissues composed of thousands of cells. Our bodies contain trillions of cells‚ each with their own functions. When at equilibrium‚ they collaborate in harmony. It is a beautiful symphony of regulation‚ proliferation‚ and complex communicat‚ion. Each and every one of us is a universe of microcosms. Cellular
