We have three types of cells in the blood, red, white, and platelets. Red blood cells transport oxygen throughout the body while white blood cells help protect us against infection. Platelets are involved in clotting. When you get a cut your vessels send out signals calling for for platelets and proteins to help in clotting. In addition, white blood cells also come to the rescue. A blood clot is a group of chemicals and cells that work together to stop the flow of blood in a small area.

Although the thought has always intrigued me, it never really occurred to me what a feat hibernation actually is. It turns out that all of the bears, squirrels, rabbits etc…. that I thought were just sleeping, are breaking biological laws!! If I was to stay dormant for 5 months, without food or drink and little to no movement in freezing temperatures I would die, so no hibernating <a class="more-link" href="http://blogs.dnalc.org/2012/02/16/hibernation-why-not-me/">More ></a></p> </div> <div class="post-tags"> <a href="http://blogs.dnalc.org/tag/dna/" rel="tag" title="dna (36 topics)">dna</a>, <a href="http://blogs.dnalc.org/tag/evolution/" rel="tag" title="Evolution (9 topics)">Evolution</a>, <a href="http://blogs.dnalc.org/tag/genes/" rel="tag" title="genes (11 topics)">genes</a>, <a href="http://blogs.dnalc.org/tag/hibernation/" rel="tag" title="hibernation (1 topics)">hibernation</a>, <a href="http://blogs.dnalc.org/tag/natural-selection/" rel="tag" title="natural selection (3 topics)">natural selection</a>, <a href="http://blogs.dnalc.org/tag/sleep/" rel="tag" title="sleep (4 topics)">sleep</a> </div> </div>   <div id="post-4387" class="hentry post post-3 odd author-mcbrien category-dnafromthebeginning clear-block"> <a class="post-thumb size-post-thumbnail alignleft" href="http://blogs.dnalc.org/2011/12/20/aging-eggs/"><img width="100" height="100" src="http://blogs.dnalc.org/wp-content/uploads/2011/12/200px-CelegansGoldsteinLabUNC-100x100.jpg" class="attachment-post-thumbnail" alt="C. elegans roundworm" /></a> <h2 class="title"><a href="http://blogs.dnalc.org/2011/12/20/aging-eggs/" rel="bookmark" title="Permanent Link: Aging Eggs">Aging Eggs</a></h2> <div class="post-date"> <p class="day">Dec 20th</p> </div> <div class="post-info clear-block with-thumbs"> <p class="author alignleft">Posted by <a href="http://blogs.dnalc.org/author/mcbrien/" title="Posts by Amanda McBrien ">Amanda McBrien</a> in <a href="http://blogs.dnalc.org/category/sitetopics/dnafromthebeginning/">DNA From The Beginning</a> </p> <p class="comments alignright"><a href="http://blogs.dnalc.org/2011/12/20/aging-eggs/#comments" class="no comments">No comments</a></p> </div> <div class="post-content clear-block"> <a href="http://blogs.dnalc.org/wp-content/uploads/2011/12/200px-CelegansGoldsteinLabUNC1.jpg"></a><p class="wp-caption-text">C. elegans Roundworm</p> <p>The aging process is, and always will be fascinating to us.

For the first nine of these days, hundreds of eggs are fertilized producing an abundance of offspring! After day nine, the many remaining eggs won’t be used, as their quality is poor and they cannot produce viable embryos. A process similar to this takes place in humans.

Most people would say infection, getting sick, germs, and other negative associations. Not only are viruses a valuable tool in research, they offer a look into history and also our own bodies. I’ve recently become a bit obsessed with learning more about them. Part of it is that I thought I knew more than I did. There is a huge amout of information just waiting to be uncovered.

For example, bitter tasting toxins can be detected in foods, and thereby avoided or at least regulated; meaning you won’t eat too much of something that tastes really bad!</p> <p>Interestingly enough, inhalable toxins can be detected in airways, just like they would be on the tongue.

Harmful bacteria, viruses, and fungi can enter your system and cause diseases. In addition to relying on your immune system, it is helpful to avoid contact with germs by thoroughly washing your hands and keeping your environment clean.</p> <p>How is it possible that some organisms have the ability to survive in some of the dirtiest places on earth? What survival mechanisms do they have that differ from ours?</p> <p>Scientists ground up the brains and other nerve tissues from two species of insects, the American cockroach and the desert locust.

Sometimes referred to as “junk” DNA, these regions make up about 98.5 % of our genome. Is this DNA really junk?</p> <p>Scientists have recently identified a section of “junk” DNA that can regain function and cause disease. The section of DNA is made of repeat regions of the same sequence. They found that individuals who have 1-10 repeats on the end of chromosome 4 can develop one of the most common forms of muscular dystrophy, FSHD.
