		<description><![CDATA[The creepiest our world has to offer...]]></description>
			<content:encoded><![CDATA[<p>&nbsp;&nbsp;&nbsp;&nbsp; I hate bugs.&nbsp; Very little in life scares me, but I am a complete wuss when it comes to them.&nbsp; Or even things that <i>look</i> like them.&nbsp; I took my kids to a large museum awhile back, where they had a live insects exhibit.&nbsp; 23 inch centipedes.&nbsp; 6 inch long roaches.&nbsp; There were plenty of other nasty things to look at, but I couldn&#8217;t list a one, because I was long gone at that point.</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp; We left the devilish exhibit, and the next stop was the mundane butterfly room.&nbsp; Or at least it was mundane, until one landed on the back of my neck.&nbsp; Now, I knew it was a room full of only butterflies, but I also knew with equal certainty that the foot long centipede had followed me and was now in the process of eating me.&nbsp; I made a rather hasty (and apparently, humorous) exit.</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp; So that is what bugs and things that look like them do to me.&nbsp; Allow me to share a bit of the heebie jeebies with you.</p>
<p><strong>House Centipede</strong></p>
<p>
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/BMwHqNWFOZk"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/BMwHqNWFOZk" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
</p>
<p>We&#8217;ll start with this creepy little bastard, because you might very well see this one in your home.&nbsp; The first time I saw one, it was about two inches long and I thought the gates of hell had opened up.</p>
<p><strong>Giant Centipede</strong></p>
<p>
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/Qf8pAwGsuF4"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/Qf8pAwGsuF4" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
</p>
<p>While we&#8217;re on the subject, how would you like to wake up with one of these guys on ya?</p>
<p><strong>Gaint African Millipede</strong></p>
<p>
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/N0GkGXKZSm0"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/N0GkGXKZSm0" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
</p>
<p>And then there is the millipede.&nbsp; As a pet?&nbsp; Never in life.</p>
<p><strong>The Roach</strong></p>
<p>
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/Bbzc1seUt-Q"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/Bbzc1seUt-Q" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
</p>
<p>Normal roaches are nasty enough, but imagine a herd of these.&nbsp; Whenever I see stuff like this, I flinch for hours at the slightest tickle&#8230;</p>
<p><strong>Rhinocerous Beetle</strong></p>
<p>
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/8_V5U94wFi0"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/8_V5U94wFi0" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>
</p>
<p>I can comfortably say that if I saw one of these, I would get my gun and shoot it.&nbsp; Repeatedly.</p>
<p><strong>Cthulthu Larva (Abyssmal Sea Slug)</strong></p>
<p><img src="http://s3.amazonaws.com/readers/2009/11/18/cthulhu-larva-aka-abyssal-sea-cucumber_1.jpg" alt="" /></p>
<p>Animals like this make me glad I&#8217;m neatly tucked away in Wisconsin; no where near the damn ocean.&nbsp; Doesn&#8217;t look <i>harmful</i>, exactly, but on the creepy scale it&#8217;s a 10.</p>
<p><strong>Coffin Fish</strong></p>
<p><img src="http://s3.amazonaws.com/readers/2009/11/18/coffinfish_1.jpg" alt="" /></p>
<p>Tell me this doesn&#8217;t remind you of the little ones in <i>Aliens</i>.</p>
<p><strong>Giant Isopod</strong></p>
<p><img src="http://s3.amazonaws.com/readers/2009/11/18/giant-isopod_1.jpg" alt="" /></p>
<p>Yeah, they&#8217;re like 2 feet long.&nbsp; The Flea from hell.</p>

		<description><![CDATA[While I'm looking through the daily papers I often come across odd pictures and very short stories and, having gathered a few together over the past couple of weeks I thought you might enjoy my top four contenders for the Wildlife's Got Talent contest!!]]></description>
			<content:encoded><![CDATA[<p><img src="http://s3.amazonaws.com/readers/2009/11/18/smiler1515410i_1.jpg" alt="A diver has captured a photograph of a great white shark approaching his camera with a toothy grin like that of Bruce, the terror of the 2003 film Finding Nemo" width="620" height="400" border="0" /></p>
<p>Say cheese!&nbsp; In fourth place I&#8217;d&nbsp;put this Bruce the Shark (Finding Nemo) impersonator.&nbsp;</p>
<p>The&nbsp;14 ft long white shark was snapped in the waters off the coastal Mexican resort of Guadalupe.&nbsp; The fearless photographer maintains that he wasn&#8217;t in any danger &#8211; he apparently had a &#8220;100% safety record&#8221; and&nbsp;went on to say that great whites aren&#8217;t as ferocious as they&#8217;re made out in the Jaws movies.&nbsp; I&#8217;ll take his word for that but don&#8217;t think I&#8217;ll take up shark photography myself!</p>
<p><img src="http://s3.amazonaws.com/readers/2009/11/18/bear1521490c_1.jpg" alt="Polar bear photographed blowing bubble" width="460" height="288" /></p>
<p>In third place is this polar bear giving his rendition of I&#8217;m Forever Blowing Bubbles.</p>
<p>Polar bears&nbsp;are&nbsp;found mainly in&nbsp;the Arctic circle and&nbsp;are the world&#8217;s largest carnivore species found on land.&nbsp;They&#8217;re also the largest of the bear species.&nbsp;&nbsp;Unfortunately&nbsp;these beautiful creatures&nbsp;are classified as a vulnerable species, according to the International Union for Conservation of Nature, with 5 of the 19 sub populations in decline due to hunting and climate change.</p>
<p><img src="http://s3.amazonaws.com/readers/2009/11/18/lionopenarticle1523888c_1.jpg" alt="Lion opens family's car door with his teeth" width="460" height="288" /></p>
<p>In&nbsp;second place is this&nbsp;talented lion.&nbsp;</p>
<p>The picture was taken by a tourist who was travelling in the car behind.&nbsp; The victims were&nbsp;enjoying the view&nbsp;when the 300lb lion walked calmly across, firmly took the rear door handle with his teeth and pulled it open in one deft movement.</p>
<p>Apparently it took several seconds for&nbsp;the dire situation&nbsp;to sink into the car&#8217;s occupants but eventually they hit the accelerator and ran for the hills!&nbsp; The lion followed on until the enclosure gates were reached where a warden hurled stones to&nbsp;encourage it to go back.&nbsp;&nbsp;A spokesman from&nbsp;the Safari Park in Johannesburg said that even if the lion had got into the car, it was unlikely to attack the occupants as all the animals are well fed.&nbsp; All very well for you to say mate, but think of the muddy paws and the amount of fur a thing that size would leave in your vehicle!!!&nbsp; It&#8217;s bad enough with a dog; but a lion??</p>
<p><img src="http://s3.amazonaws.com/readers/2009/11/18/penguin1521677c_1.jpg" alt="Emperor penguin 'prepares to take photo'" width="460" height="288" /></p>
<p>Now this has to be my winner.&nbsp;</p>
<p>David Schultz, the photographer, had been taking regular visits from a helicopter base camp to the main emperor penguin rookery in Antarctica over some time to film them and had obviously piqued their curiosity.&nbsp;&nbsp;Eventually it all became too much for them so they ventured towards David to have a closer look.&nbsp; David backed away from his camera to see what they did and, to his amazement one of the three looked through the view finder while the other two posed!&nbsp; Fortunately David had another camera so he was able to&nbsp;take this&nbsp;remarkable picture.</p>

		<description><![CDATA[If you have ever watched Star Trek, you will know that they used many futuristic devices. Here we will take a look at some of those devices that are actually in existence in real life.]]></description>
			<content:encoded><![CDATA[<p><a href="http://en.wikipedia.org/wiki/Image:StarTrek_Logo_2007.JPG" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/18/startreklogo2007_1.jpg" alt="" width="220" height="275" border="0" /></a></p>

<h3>Cloaking Device</h3>
<p>The ability to truly cloak something in warfare would greatly improve the chances of victory. The British Army have already managed to successfully do it. They managed to &#8216;hide&#8217; a 60 tonne tank just by projecting images from behind the tank to the front, giving the impression that there was nothing there.</p>
<h3>Communicator</h3>
<p>Sitting proudly on the uniform, all Captain Kirk had to do was hit the button and he could talk to anyone else. The crazy thing is, it actually exists. Vocera Communications has made the device like-for-like, using hands-free voice activated devices (carried around the neck) they can talk to all their fellow workers.</p>
<h3>Holodeck</h3>
<p>Virtual reality made good. In the series, all a crew member had to do was step on to the holodeck and they would be whisked away into whatever place they wanted to be. Similar technology is being worked on in the real world. MotionWare headsets already exist that trick your brain into thinking you are somewhere you are not.</p>
<h3>Hypospray</h3>
<p>In the original Star Trek, Dr Leonard McCoy used a hypospray to administer medicine without the use of needles. Back in the real world, a Massachusetts Institute of Technology chemical engineer has designed a device that parts the skin temporarily, thus allowing any medicine to pass through freely.</p>
<p><a href="http://en.wikipedia.org/wiki/Image:LeonardMcCoy.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/18/leonardmccoy_1.jpg" alt="" width="346" height="259" border="0" /></a></p>
<p>Image via <a href="http://en.wikipedia.org/wiki/Image:LeonardMcCoy.jpg" target="_blank">Wikipedia</a></p>
<h3>Phaser Gun</h3>
<p>Set phasers to stun &#8211; sounds good doesn&#8217;t it? It is not far from becoming reality. The US defence firm Ionatron is in the process of developing laser guided, directed energy weapons that can annihilate or stun. The company are also currently developing weapons for the US military.</p>
<h3>Super Glass</h3>
<p>If you are going to be flying through space and have no idea what you may encounter, it would be ideal to have some kind of super glass protecting the windows of your craft. The US Air Force has developed a type of super glass that can withstand bomb blasts and armour-piercing bullets.</p>
<h3>Tractor Beam</h3>
<p>It would be a amazing if you had a spaceship that had a tractor beam, hauling in nearby spaceships at any time you wanted. A version currently exists. Scientists at St Andrews University created a tractor beam of sorts, they successfully used it to move glass beads with a beam of light under a microscope.</p>
<h3>Tricorder</h3>
<p>In Star Trek, they used a tricorder to detect any illnesses in the body, merely by moving the device over it. There is a version in existence just now but it is limited to detecting pneumonia by sampling the air the patient breathes.</p>
<h3>Universal Translator</h3>
<p>Wouldn&#8217;t it be good if there was a gizmo that allowed you to translate any type of alien speak into English so you could understand it? Well it already exists &#8211; sort of. A device currently exists that translates most Earth languages and speaks them back to the recipient.</p>
<h3>Warp Speed</h3>
<p>In Star Trek, the Enterprise could travel faster than the speed of light. NASA haven&#8217;t yet managed to reach such speeds. They have managed to reach speeds of 17,000mph but a new engine they have been working on will have a top speed of 34,000mph and scientists believe that it could make interplanetary space travel a reality.</p>

			<content:encoded><![CDATA[<p><a href="http://commons.wikipedia.org/wiki/Image:Verbena_bonariensis1.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/17/verbenabonariensis1_1.jpg" alt="" width="540" height="405" border="0" /></a></p>

<p>It&rsquo;s unbelievable how this Vampire phenomenon has hit our culture! On TV, in movies, in books &ndash; we just can&rsquo;t seem to escape these blood sucking bachelors. And just as many vampire stories there are out there, there are even more vampire legends. What harms a vampire- Garlic? A wooden stake in the heart? How about a little flower.</p>
<p><a href="http://www.flickr.com/photos/28821738@N05/3750776739" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/17/375077673958625db15f_1.jpg" alt="" width="500" height="375" border="0" /></a></p>
<p>Image by <a href="http://www.flickr.com/photos/28821738@N05/3750776739" target="_blank">watchwithkristin</a> via Flickr</p>
<p>In the CW hit show &ldquo;Vampire Diaries&rdquo; we&rsquo;re seen people use something called Vervain to combat a threatening vampire. It doesn&rsquo;t kill the vampire. It just sort of evens the playing field, weakening a vampire enough to get a stake through the heart or lock him away in a casket.</p>
<p>If you think this Vervain is something totally made up by the people at the CW, well then you&rsquo;re dead wrong. Vervain, also called Verbena, is a type of flower. It&#8217;s been in use since at least the middle ages where it was often used as a type of herb.</p>
<p>But Vervain is no simple flower or herb. Even before people have been writing about vampires falling in love with high school girls, the flower has been associated with divine and supernatural forces. There&rsquo;s a popular story about how Vervain was used to try to stop Jesus&#8217; wounds from bleeding after he was taken down from the cross. Other ancient legends claim this flower can protect you from vampires.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Verbena_rigida0.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/17/verbenarigida0_1.jpg" alt="" width="540" height="405" border="0" /></a></p>
<p>Image via <a href="http://commons.wikipedia.org/wiki/Image:Verbena_rigida0.jpg" target="_blank">Wikipedia</a></p>
<p>It&rsquo;s good to remember that while vampires may be the current hot thing in our culture, it&rsquo;s definitely not new or original. So it&rsquo;s great to see one of these vampire stories looking back into real culture and legends for elements to add to the tale.</p>
<p>So, here&rsquo;s what you need to know to stay safe from vampires: Mix Vervain in a tea, wear it in your hair, put the oils in a bath. However you use it, just keep this stuff around and supposedly you and your neck will remain puncture-free. Unless, of course, you&rsquo;ve become smitten with the likes of Edward, Damon and Stefan&#8230; then I guess Vervain is just not for you.</p>

			<content:encoded><![CDATA[<p>Everyone has at one time or anotherAlvin and the Chipmunks&nbsp;seen the little brown, black and white striped, bushy tailed relative of the mouse, the chipmunk. Whether in our backyards or as the cartoon versions, Chip and Dale or Alvin and the Chipmunks, most people think of them as cute. So if they are so cute, then why haven&#8217;t they, like their mice and rat cousins, been domesticated? The answer to that question may have to do with the fact that they are ubiquitous in the wild in the United States and Asia. As common as squirrels, a close relative in the animal kingdom. Though mice and rats are also very common, they hide most of the time and are not seen in their natural habitat as frequently as squirrels and chipmunks, making them just slightly more exotic. (Unless we are talking about city rats, which are fearless and seem capable of overthrowing the human race in terms of who is on top of the food chain!)</p>
<p>Like squirrels, chipmunks are frequently considered pests. Like all rodents they carry disease and in fact may be more common carriers of rabies than dogs, cats, or squirrels. If they somehow get into your home from the wild they can do a great deal of damage.&nbsp;</p>
<p>Most of us think of chipmunks as mostly seed and grain eaters, but they are omnivorous and in addition to seed and grain will eat bird&#8217;s eggs, fungi, small frogs, worms and insects. But they are hoard&nbsp;animals as well, stashing grain and seed over winter months. They live in burrows that can be up to 3.5 meters in length, usually with several &#8220;secret&#8221; or hidden entrances. Interesting to note is that chipmunks also have different rooms in their burrows which have different functions. For example, their sleeping area is separate from their pantry, and their bathroom is separate from both of those. It makes one wonder if this arrangement was part of the inspiration for the cartoon chipmunks, Chip and Dale.</p>

		<description><![CDATA[The preservation of the whale and its environment has far reaching repercussions for humans.]]></description>
			<content:encoded><![CDATA[<p>Many species of whale are under threat of extinction but the changes needed to ensure their survival are the same as the ones needed to ensure the continued survival of the planet as a whole.</p>
<p>All mammals breathe air into their lungs and whales are no exception. These aquatic mammals are descendants of mammals that have gone back to the sea and those huge creatures were of the order artiodacyla and they had many similarities to the modern day hippopotamus.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Bowheads42.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/14/bowheads42_1.jpg" alt="" width="540" height="353" border="0" /></a></p>

<p>Molecular biology and DNA testing gives convincing evidence for this connection and verifies that whales entered the water approximately 50 million years ago. Whales are divided into two broad groups called baleen and toothed whales. There was a third group but this is now totally extinct.</p>
<p>The first group of whales has a sieve like mesh at the back of the mouth which strains plankton and microscopic creatures from the water. This group contains the largest species of whales which seems strange because, logically, it would be expected that the larger species would feed of the larger, more substantial food source.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Humpback_stellwagen_edit.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/14/humpbackstellwagenedit_1.jpg" alt="" width="540" height="306" border="0" /></a></p>
<p>Image via <a href="http://commons.wikipedia.org/wiki/Image:Humpback_stellwagen_edit.jpg" target="_blank">Wikipedia</a></p>
<p>The second group is the toothed whale that preys on squid, fish or both. This is the group that has such a sensitive and accurate echo location system. This system is also known as biosonar and is also found in other mammals including dolphins, shrews and bats. Echo locating animals project sound and listen for the echo that comes back and this helps them to navigate, or hunt.</p>
<p><a href="http://www.flickr.com/photos/36121888@N08/3623934742" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/14/3623934742b674785c0e_1.jpg" alt="" width="500" height="333" border="0" /></a></p>

<p>Changes in the environment and the increasing use of sonar equipment on board ships has affected the toothed whales very badly. It disrupts their sonar so that hunting is not as effective and it misdirects their navigational abilities. This could be a major contribution to the disturbing incidences of whales beaching themselves, or getting stuck upstream in rivers.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Sperm_Whale_about_to_Dive.jpeg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/14/spermwhaleabouttodive_1.jpeg" alt="" width="540" height="406" border="0" /></a></p>
<p>Image via <a href="http://commons.wikipedia.org/wiki/Image:Sperm_Whale_about_to_Dive.jpeg" target="_blank">Wikipedia</a></p>
<p>Whales are warm blooded creatures and they give birth to live young, just like other mammals do.</p>
<p>They feed their young milk from mammary glands and even have hair on their bodies. All these things are proof of the link with land mammals.</p>
<p>The body of the whale is like that of a fish but remnants of forelimbs can be seen in the creature&#8217;s front flippers. The tail holds the fluke which enables propulsion. Most whales do not have hind limbs but there are a couple of exceptions to this rule. Sperm whales and baleen whales sometimes have very simple back limbs. Most whales also have a dorsal or back fin.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Fin_Whale_feeding.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/14/finwhalefeeding_1.jpg" alt="" width="500" height="333" border="0" /></a></p>
<p>Image via <a href="http://commons.wikipedia.org/wiki/Image:Fin_Whale_feeding.jpg" target="_blank">Wikipedia</a></p>
<p>Beneath the skin of the whale is a thick layer of blubber, or fat, which provides insulation and it is for this fatty layer that whales have been hunted almost to extinction in some cases.</p>
<p>Whales breathe through blow holes which are located at the top of their heads. This location enables the whale to breathe and still remain submerged. Baleen whales have two blow holes and baleens have one. After a dive whales blow out water spouts which vary in shape according to species. A sperm whale can stay underwater for up to two hours without having to surface for air.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Bluewhale877.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/14/bluewhale877_1.jpg" alt="" width="500" height="315" border="0" /></a></p>
<p>Image via <a href="http://commons.wikipedia.org/wiki/Image:Bluewhale877.jpg" target="_blank">Wikipedia</a></p>
<p>The lifespan of the whale is estimated to be somewhere between thirty and ninety years depending on their species. However evidence of whales reaching more than one hundred years of age has also been found. In one particular instance part of a lance used by whalers in the 1800&#8217;s was found embedded in a bowhead whale which was caught off the coast of Alaska.</p>
<p>Male whales are known as bulls, females are called cows and their offspring are called cows and they tend to live in groups. Communication between whales is based on a series of sounds called whale song. These sounds are very loud because these are such large creatures and sperm whales have also been heard emitting a series of clicks. This is how these amazing creatures operate their inbuilt sonar system. They have been known to emit 20,000 watts of sound at 163 decibels. That&#8217;s a lot of noise when you consider that a blast from a shotgun reaches 130 decibels and a rocket launch generates 180 decibels. That places whale song somewhere between these two in volume.</p>

<p><a href="http://en.wikipedia.org/wiki/Image:Humpback_Whales_in_antarctica.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/14/humpbackwhalesinantarctica_1.jpg" alt="" width="540" height="298" border="0" /></a></p>

<p>Whales do not usually form lasting bonds during the mating season and a cow may have several male partners during one season. Cows usually only give birth to one calf which is born tail first and suckles milk directly from its mother. Whale milk is a very thick, pasty substance and is actively squirted into the mouth of the suckling calf by the mother so that none of it gets lost in the water.</p>
<p>Sonar interference and whaling are endangering many whale species but these are not the only hazards they face. Seismic testing for oil and gas is thought to disrupt whale sonar and changes in the earth&#8217;s magnetic field may also be a factor in beaching. Fishing gear and collisions with ships frequently cause injury, or death and toxins known as persistent organic pollutants cause even more serious problems, These toxins can cause hearing loss in whales and so disrupt the fine tuning needed for their sonar operation.</p>
<p>Culturally whales have featured in stories and legends. For example in Pinocchio where the puppet and his father are swallowed by a whale and the tale of the great white whale, Moby Dick. The whale is mentioned in the Bible, &#8216;And God created great whales&#8217;, (Genesis 1:21) and in the Qur&#8217;an in the story of Jonah being swallowed by a great whale.</p>
<p>There are fourteen known species of baleen whales and of these the best known are Bowhead, Humpback Whale, Blue Whale and Grey Whale. The toothed whales number twenty six species including the Sperm Whale, Narwhal and Beluga.</p>
<p>A third group of whales is now thought to be extinct. The archaeoceti group were the forerunners to the modern whale. In 2004 fossils of an unknown extinct archeoceti were discovered and the species was named Harrison&#8217;s Whale after the discoverer. Sadly, not all extinct whales come from this group.</p>
<p>The Blue Whale is the world&#8217;s largest mammal and reaches up to thirty-three metres long with a weight of one hundred and ninety tonnes. It is thought to be the largest animal of any kind, ever to have lived on the earth. During the twentieth century, these creatures were hunted almost to distinction. In the middle of the 1960&#8217;s the blues were protected and this has helped their numbers to recover in the southern oceans. The last count was an estimated 2,300 and growth of about 7% per year has been seen since. (Figures courtesy of the BBC News Channel) and there is also evidence of an increase in numbers in the North Atlantic region.</p>
<p>The Bowhead Whale which is a particularly slow moving species has been protected since 1937. It grows up to 20 metres in length and inhabits the Arctic and Sub Arctic Seas. Although these whales are protected, native peoples are still permitted to hunt them for food. The Bowhead&#8217;s numbers are recovering in the Bering Sea, Chukchi and Beaufort Seas but the process is slower around Greenland and Baffin  Island. It is thought that there are just 8000 Bowhead Whales in existence at this time.</p>
<p>The Fin Whale grows to about eighteen metres long and is found in north and south hemispheres. These creatures swim in pods of seven or eight individuals and eat mostly krill and herring. They have been so over fished and seen as a threat to herring fisherman that their numbers are sharply declining.</p>
<p>These are not the only threatened whale species. There are many more including the grey whale, humpback whale, and the Sei Whale. As our seas become more polluted and climate change plays havoc with food supplies for these creatures and other marine life we are in serious danger of killing these wonderful creatures off completely.</p>
<p>Coral reefs, their enormous variety of marine life and the sensitive eco systems surrounding them are also subject to the same destructive elements. Small changes in these areas have huge knock on effects in all the oceans of the world. This, combined with current changes, wind direction changes above the water have a far reaching effect on climate, drought and flood and so threaten our entire existence. Saving the whales now will have real long term benefits for the human race as a species. What is good for them now will eventually be food for us too.</p>
<p>It would be a very sad thing indeed if generations to come never saw whales, seahorses, walruses, penguins and starfish except in picture books, because we failed to do enough to protect them and their environment.</p>
<p>There is more at stake than preserving marine life and protecting whales because they are part of the same finely balanced eco system in which we live. The steps we need to take to make changes for these creatures are the same steps that are needed to save the very earth we live on and secure our own future as a species.</p>

		<description><![CDATA[Things are beginning to look up for the creature on which Kenneth Grahame based his Ratty character in Wind in the Willows, but unfortunately Beatrix Potter's poor Mrs Tiggywinkle isn't faring quite so well!]]></description>
			<content:encoded><![CDATA[<p><img src="http://s3.amazonaws.com/readers/2009/11/11/watervole460x276_1.jpg" alt="" /></p>
<p>As most kids from 3 to 103 will know, Ratty was one of the prominent characters in Kenneth Grahame&#8217;s wonderful book &#8220;The Wind in the Willows&#8221;,&nbsp;but early illustrations show that Ratty wasn&#8217;t a rat in the true sense of the word but was more probably a water vole.&nbsp; These attractive little creatures, around 20 years ago, could be found in great abundance on almost all of Britain&#8217;s waterways but numbers have declined by 90% since the 1980s.&nbsp; But, just like Ratty, he&#8217;s putting up a damned good fight and water vole numbers are slowly on the increase.</p>
<p>However, Ratty&#8217;s decline wasn&#8217;t due to standing his ground against the evil weasels and stoats as in the story but due mainly to us humans who have been polluting the waterways and flinging pesticides hither and thither across the land.</p>
<p>In order to combat the decline of this cheeky little chappy recent legislation&nbsp;was put in place&nbsp;by way of a fine of &pound;5,000 to anyone who injured one or disturbed his habitat.&nbsp; Surprisingly, this legislation seems to have had some effect and this year&#8217;s British Waterways wildlife survey has revealed that, although these voles are still extremely rare, there were 89 sightings &#8211; twice as many as last year.&nbsp; Most of the sightings seem to have been along the banks of the Kennet and Avon canal in southern England.</p>
<p>The survey was conducted by members of the public who reported on the various creatures they saw along the 2,000 mile network of canals and waterways and not only did it reveal a considerable increase in the number of water voles but, among a total of 42,500 sightings of wildlife, 127&nbsp; birds and&nbsp;27 butterfly species&nbsp;were spotted and three times as many frogs were spotted this year compared&nbsp;to last.</p>
<p>The top three sightings will come as no surprise to UK residents &#8211; there were over 7,000 sightings of mallard ducks, around 2,500 sightings of Canada geese, and almost 2,500 sightings of swans.</p>
<p>Other top sightings were moorhens, starlings, bumblebees,&nbsp;rabbits, house sparrows, coots and sticklebacks.</p>
<p>It was also good to see kingfishers fairly high on the list, although unfortunately not in the Top 20.&nbsp;&nbsp;These fussy little birds like nice clean water &#8211; not your &#8220;bog standard&#8221; muck &#8211; so it bodes well for next year&#8217;s wildlife if the waters are contaminate free.</p>
<p>Two of the most bizarre beasties spotted were a porpoise in the River Ouse&nbsp;near Selby in North Yorkshire but being ever sceptical I do wonder whether this was spotted by a Theakston&#8217;s Old Peculier imbiber (a very well known English Ale to those of you not from the UK!) and, even more &#8220;Peculier&#8221; was the sighting of a large alligator snapping turtle (US native) which was found in the Earlswood Reservoir in Solihull&nbsp;&nbsp; Quite why he&#8217;d want to go to Solihull I have no idea, but it&#8217;s thought that he may have been a &#8220;family pet&#8221; but became a little too large to handle!!!</p>
<p><img src="http://s3.amazonaws.com/readers/2009/11/11/800pxerinaceuseuropaeus_1.jpg" alt="" /></p>
<p>And now on to Mrs Tiggywinkle.&nbsp; She&#8217;s been snuffling around our gardens for centuries helping us veggie growers to ward off the evil slugs and snails which creep around unseen and unheard&nbsp;in the twilight zone but, due to our modern gardening fads she&#8217;s finding it difficult to find her way!</p>
<p>Due to the latest&nbsp;British fad for&nbsp;decking, patios, secure fencing and Mediterranean style gardens with stone or slate surfaces,&nbsp;Mrs T and her family are&nbsp;unable to get into many of our gardens and, if they do manage it,&nbsp;they&nbsp;can&#8217;t find&nbsp;food.&nbsp; So, the next time you&#8217;re doing a garden make-over please consider the Tiggywinkle family!&nbsp; Thankfully my driveway isn&#8217;t gated, and access from the drive into the back garden isn&#8217;t either.&nbsp; I then have grass, and flower/vegetable&nbsp;beds so&nbsp;they can happily&nbsp;come in for a spot of slug and chips of an evening and&nbsp;they have&nbsp;no need to take the same route home &#8211; I&#8217;ve got a natural native British hedge at the bottom of the garden which was planted two or three years ago to replace a fence, and this leads into a meadow so my conscience is totally clear!&nbsp; The only drawback&nbsp;in having one of just a handful of gardens in the locality which is a hedgehog haven is that I do have to dodge the hedgehog poo when I walk down the garden, but it&#8217;s a small price to pay!</p>

		<description><![CDATA[Some scientists will do anything for their love of science. Here we will take a look at some scientists who were either injured or died because of their work.]]></description>
			<content:encoded><![CDATA[<h3>Alexander Bogdanov</h3>
<p>In 1924, Bogdanov started experimenting on himself. The Russian physician would give himself blood transfusions and he claimed that it had stopped his baldness and improved his eyesight. Four years later, another transfusion of blood infected with tuberculosis and malaria caused his death.</p>
<h3>Carl Scheele</h3>
<p>Famed pharmaceutical chemist, Scheele discovered many different types of chemical elements. He also discovered a process that was very similar to pasteurisation. Unfortunately for Scheele, he had a bad habit of tasting everything he discovered. He died of symptoms very similar to mercury poisoning.</p>
<h3>Sir David Brewster</h3>
<p>Brewster was the Scottish inventor of the kaleidoscope. His main interests were, of course, optics and light polarisation. In 1831, a chemical experiment he was working on went terribly wrong and it almost blinded him. Brewster had eye difficulties for the rest of his life.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Dbrewster.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/13/dbrewster_1.jpg" alt="" border="0" /></a></p>
<p>Image via <a href="http://commons.wikipedia.org/wiki/Image:Dbrewster.jpg" target="_blank">Wikipedia</a></p>
<p>&nbsp;</p>
<h3>Elizabeth Ascheim</h3>
<p>Ascheim was the wife of Dr Woolf, they both had a major fascination with the x-ray machine (invented by Wilhelm Conrad Rontgen). The couple spent years experimenting with the machine which was attributed to the widespread and violent cancers they died from.</p>
<h3>Galileo Galilei</h3>
<p>Galileo is famed for his work on refinement of the telescope. He was overly fascinated with the sun and spent a lot of his time staring at it. Not surprisingly, this led to extreme damage to his retinas which left him blind for the last 4 years of his life.</p>
<h3>Sir Humphrey Davy</h3>
<p>On the bright-side (for the world at least) Davy&#8217;s work on various gases led to the discovery of the anaesthetic properties of nitrous oxide. Unfortunately for him personal, the inhaling of the gases he worked with led him to become an invalid for the last 20 years of his life.</p>
<h3>Jean-Francois de Rozier</h3>
<p>De Rozier was a famed physics and chemistry professor. He assisted in the first untethered balloon flight, which included a sheep, a chicken and a duck. He went on to attempt the first crossing of the English Channel by balloon. It was just an attempt because the balloon deflated and he fell to his death.</p>
<h3>Marie Curie</h3>
<p>It was in 1898 that Curie and her husband Pierre discovered radium and polonium. She was a double Nobel Prize winner for her work spent performing radiation research and studying radiation therapy. It caught up with her though as the constant exposure led to her contracting leukaemia.</p>
<p><a href="http://commons.wikipedia.org/wiki/Image:Mariecurie.jpg" target="_blank"><img src="http://s3.amazonaws.com/readers/2009/11/13/mariecurie_1.jpg" alt="" border="0" /></a></p>
<p>Image via <a href="http://commons.wikipedia.org/wiki/Image:Mariecurie.jpg" target="_blank">Wikipedia</a><br /><a href="http://commons.wikipedia.org/wiki/Image:AlfredNobel.jpg" target="_blank"></a></p>
<h3>
<p>Michael Faraday</p>
</h3>
<p>Two bits of bad luck for Faraday. It was bad enough for him that he suffered from the effects of chronic chemical poisoning, but he also suffered sever damage to his eyes after a nitrogen trichloride explosion. It didn&#8217;t dampen his spirits though.</p>
<h3>Robert Bunsen</h3>
<p>Bunsen will, of course, always be noted for lending his name to the Bunsen burner, the standard way to torch something in a classroom. Bunsen almost died twice of arsenic poisoning. After an explosion of cacodyl cyanide one day in his lab as he worked, he lost the sight in his right eye permanently.</p>

			<content:encoded><![CDATA[<p><p>It is impossible to tell the different between male and female embryos until they are between eight and ten weeks old. There are no outwardly visible signs until after this time, so an ultra sound would not be able to tell.</p>
<p>What happens after twelve weeks will depend on the type of chromosomes which have been inherited from the parents of the embryo.&nbsp; A pattern of two X chromosomes, known as XX, means that the inherited chromosomes are female.&nbsp; If they are made up of one Y and one X chromosome, the scientific pattern is XY and the embryo will be male.</p>
<p>The embryo always inherits an X chromosome from the mother, but the father can pass on another X or a Y chromosome. So it is the father who determines the sex of the baby.&nbsp; This natural selection of chromosomes appears to be random but scientists are still examining the evidence to find out exactly what determines the type of chromosome that the father passes on.&nbsp; Families where there are all girls, or all boys, may eventually give the clue to how selection is made.</p>
<p>After twelve weeks, depending on the chromosome pattern, testes or ovaries are produced. If testes develop they make a chemical which stops the female reproductive organs from developing.&nbsp; Testosterone is also produced and this stimulates the growth of male reproductive organs.</p>
<p>Chromosomes do not simply determine the sex of a baby. They also determine physical strength and character and if the balance between the chromosomes is abnormal the baby develops mixed characteristics. For example, tests done on some female athletes in the past showed abnormal XXY chromosome patterns.&nbsp; This in effect means that they have a third male chromosome as well as their two female ones.&nbsp; &nbsp;This gives them extra strength and men with an extra Y chromosome giving them an XYY pattern are usually bigger and more aggressive than average. &nbsp;In fact there has been research in the US which suggests that men with this extra Y chromosome may be more likely to be involved in crime.</p>
<p>So, it seems that there may actually be four sexes instead of just the two we have been accustomed to collecting. There is XX, XY, but then there is XXY and XYY. This certainly gives a great deal of food for thought.</p></p>

		<description><![CDATA[Information about the commonly seen bird on the North American continent, the Blue Jay.]]></description>
			<content:encoded><![CDATA[<p>Blue Jays are particularly beautiful birds, known and named for their deep blue color and strong black and white striping on their wings. They are also known for being very loud and territorial, often chasing other types of birds away from feeders so that they can claim a feeder or particularly abundant food source as their own and have an easier time foraging. They are also rumored to be egg snatchers, stealing eggs from the nests of other birds to eat. While egg-snatching is much noted, it is not as widely spread behavior among jays as it was once thought to be.&nbsp;Like their cousins of the Corvidae family, crows and ravens, the Blue Jay is an omnivore.</p>
<p>One interesting fact about the blue color of the Blue Jay&#8217;s feather is that the brilliant hue does not come from pigmentation, but rather the structure of the feather itself. If you were to crush the feather, the blue would disappear. Something else a lot of folks don&#8217;t realize about the Blue Jay is that they also mimic sounds, from the barks and meows of cats and dogs, to the bird calls of other species, to human speech. One of the smartest birds, they have been observed to be capable of planning ahead, watching humans plant seeds, then waiting for the humans to leave, then swooping in to dig up the seeds.</p>
<p>The decorative crest on top of the Blue Jays head can be a barometer for their mood. If the crest is fully raised, the bird is feeling excited or agressive, it is usuallt flat against the head when the bird is in a comfortable state, such as when eating with its mate. Blue Jays, surprisingly, mate for life. Mating season for Jays last from mid march into July and it takes 17-21 days for a brood of eggs, generally 4-5 in number, to incubate. The baby Jays stay with Mom and Dad Jay until the end of fall, when the family disperses. This is done to avoid competition over sources of food.</p>
