The Biology Project What If All 7.1 Billion People Moved To Tunisia? I’ve always been interested in the distribution of the human population across the globe. It’s far from an even spread—this map shows where people are most squished in (dark colors) and where they’re spread out (light colors): And the East Asian countries in particular are so jam-packed with people that there’s this insane fact: (Parts of Malaysia and Indonesia have been intentionally left out—without them, the red regions still contain more than 50.2% of the world’s population.) To gain perspective on just how differently people are living on this planet, I looked up the average population density of a particular city, state, or country, and imagined all humans living at that density. (While we’re here—if all the habitable land on Earth were as dense as Manhattan, you could fit 1.73 trillion people on the planet.
Anatomy of the Vertebral Column The vertebral column (also known as the backbone or the spine), is a column of approximately 33 small bones, called vertebrae. The column runs from the cranium to the apex of the coccyx, on the posterior aspect of the body. It contains and protects the spinal cord This this article, we shall look at the functions of the vertebral column as a whole, the general anatomical structure of a vertebrae, and look at some of the clinical syndromes that can occur. Fig 1.0 – The vertebral column viewed from the side. The most important functions of the vertebral column are as follows: Protection: it encloses the spinal cord, shielding it from damageSupport: it carries the weight of the body above the pelvis (below the pelvis, the lower limbs take over)Axis: the vertebral column forms the central axis of the body.Movement: it has roles in both posture and movement The vertebral column can be separated into five different regions. Vertebral Body This is the anterior part of the vertebrae. Vertebral Arch

Towards the end of October we start seeing lots of recipes for pumpkin this and pumpkin that. This one is different. We're going to extract the DNA from a pumpkin. What you need: A pumpkin. What we do with all that stuff Cut the pumpkin into small chunks that fit in the blender. Add about a half cup of water to the pumpkin chunks, and a tablespoon of salt. Now we add a whole bunch of dishwashing detergent. Next we filter the puree using the coffee filter and funnel. Now it is time to get the liquor out of the freezer. For this part, a shot-glass would be appropriate. Pour some of the filtered pumpkin juice into the container. Now, tilt the container and very gently pour some of the alcohol slowly so that it forms a layer on top of the juice, and does not mix. After a few seconds, you will see a ghostly layer of DNA form between the juice and the alcohol. Pumpkin is made of water, cellulose, sugars, proteins, salts, and DNA.
15 TED Talks That Will Change Your Life How does caffeine affect the body? Biologist Neal J. Smatresk--Dean of the College of Science at the University of Texas at Arlington--offers this explanation: Caffeine--the drug that gives coffee and cola its kick--has a number of physiological effects. Historically, cAMP was the first second messenger ever described. Thus, when caffeine stops the breakdown of cAMP, its effects are prolonged, and the response throughout the body is effectively amplified. Caffeine would be expected to have this effect on any animals that used these neurotransmitters to regulate their heartbeat.
Terrifying images from the microscope (16 pictures These spectacular images were captured using a variety of traditional micrioscoape. The world they show is terrifying! When viewed up close beneath the unblinking eye of the microscope, the tiniest mites and most harmless of insects become terrifying beasts that haunt your dreams.

How do you cite website material that has no author, no year, and no page numbers? Because the material does not include page numbers, you can include any of the following in the text to cite the quotation (from pp. 170–171 of the Publication Manual): A paragraph number, if provided; alternatively, you could count paragraphs down from the beginning of the document. An overarching heading plus a paragraph number within that section. A short title in quotation marks, in cases in which the heading is too unwieldy to cite in full. Because there is no date and no author, your text citation would include the title (or short title) "n.d." for no date, and paragraph number (e.g., "Heuristic," n.d., para. 1). The entry in the reference list might look something like this: Heuristic. (adapted from the sixth edition of the APA Publication Manual, © 2010) Because the material does not include page numbers, you can include any of the following in the text to cite the quotation (from pp. 170–171 of the Publication Manual): Heuristic. Heuristic.
100 Weird Facts About the Human Body 100 Weird Facts About the Human Body Friday, April 2, 2010 at 5:23pm by Site Administrator The human body is an incredibly complex and intricate system, one that still baffles doctors and researchers on a regular basis despite thousands of years of medical knowledge. As a result, it shouldn’t be any surprise that even body parts and functions we deal with every day have bizarre or unexpected facts and explanations behind them. From sneezes to fingernail growth, here are 100 weird, wacky, and interesting facts about the human body. The Brain The human brain is the most complex and least understood part of the human anatomy. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Hair and Nails While they’re not a living part of your body, most people spend a good amount of time caring for their hair and nails. Facial hair grows faster than any other hair on the body. Internal Organs The largest internal organ is the small intestine. Bodily Functions Sex and Reproduction
Writing in Psychology: Experimental Report Writing Summary: Written for undergraduate students and new graduate students in psychology (experimental), this handout provides information on writing in psychology and on experimental report and experimental article writing. Contributors:Dana Lynn Driscoll, Aleksandra KasztalskaLast Edited: 2013-03-11 09:54:55 Experimental reports (also known as "lab reports") are reports of empirical research conducted by their authors. You should think of an experimental report as a "story" of your research in which you lead your readers through your experiment. As you are telling this story, you are crafting an argument about both the validity and reliability of your research, what your results mean, and how they fit into other previous work. These next two sections provide an overview of the experimental report in APA format. General-specific-general format Experimental reports follow a general to specific to general pattern. Title page Experimental reports in APA format have a title page. Crafting your story
The 2013 Microscope Images of the Year The yawning trap of a carnivorous plant has taken First Prize in the 2013 Olympus BioScapes Digital Imaging Competition. Igor Siwanowicz, a researcher from the Howard Hughes Medical Institute captured the fascinating photo. The confocal image was selected from more than 2100 entries. In addition to the Top 10 award-winning recipients, 69 Honorable Mentions received recognition this year, including 55 still images and 14 movies.
