LEEUWENHOEK
39-a-antony-van-leeuwenhoek-1632-1723.jpg


-Should Leeuwenhoek be credited with being the "inventor of the first microscope"? Why/Why not?-How else has he contributed to the field of science?
Personally I do not think that Leeuwenhoek should be credited with the FIRST microscope because that was Robert Hooke. But I do believe he should have credit for inventing one of the best first microscopes. Leeuwenhoek's microscope was much better than that of Hooke's because his could see up to 100x bigger than that of Hooke's. Although the compound microscope invented before him was much simpler, I think it was important for Leeuwenhoek to make a more complex one so that being able to see the specimen even closer was an option. Because there was only a small amount of time between the two inventions I believe they should share the credit on inventing the microscopes because anything scientifically discovered back in that time was a large honor and helped in knowing what we know today. Leeuwenhoek made over 500 microscopes and that is very impressive, but what he also did was help find and discover many microscopic animals. He as well discovered bacteria, free-living and parasitic microscopic protists, sperm cells and blood cells. Leewenhoek also always kept track of all of his observations which is a very important key part in being a great scientist.

What is apoptosis?


In a nutshell, apoptosis is cell death, or some may refer to it as cell suicide. This process may occur when the body recognizes a virus. Signals are then sent to destroy the bad cell. Apoptosis only takes place in multicellular organisms.

Hopefully this miniature diagram can help!

Shubunkins

What is a Shubunkins?: The Shubunkins is a species of goldfish that is believed to be first bread in Japan. Shubunkins come in two different types, there is the Bristol Shubunkins and the London Shubunkins. These fish are best knows for their deep blue, violet, white and orange colours that make them different from other fish, such as the regular goldfish. To find a Shubunkins with a mostly blue colour is considered very rare and special to find.
Environment: They say the a pond is the best place to have a Shubunkins, they can adapt easily to change of weather during the seasons and the large space gives them plenty of room to grow. Having this species of fish in a take is not wrong though, you just need to keep in mind that you have them in the appropriate environment with plenty of room to swim and grow. Putting another fish in the Shubunkins is a good idea, you just have to make sure it is not a slow moving fish. This is because Shubunkins are very fast moving and when food arrives they will get to it very quickly therefore a slow moving fish would starve to death.
Life Span: The Shubunkins can surprising live quite long if the proper care is being done. A Shubunkins can live to somewhere near 15 year! Once this fish has reached 3 years old they are considered an adult fish.
Other: Reach a length of 9-16 inches Single tailed Will eat any type of fish food that is vegetable based

Below is a picture of me and my Shubunkins, his name is Toby. Toby was purchased on September 23, 2007 (at wal-mart of all places!!)

Appendicitis
appendiix.jpgappendicitis.jpg


What is Appendicitis? -
To know what appendicitis is you should first know what the appendix is. The appendix is a 3-4 inch long worm shaped appendage that sticks out from the large intestine and serves no purpose. Scientists can not determine what system the appendix belongs to because they are unaware of it's purpose. Some believe that the appendix was used by early man to digest leaves and rough bark.
So why such a big deal? -
Appendicitis is the inflammation and swelling of the appendix.
So when the appendix swells it gets to a point where it may rupture. If the appendix ruptures then bacteria and inflammatory fluids will spill into the abdominal cavity.These fluids can be very harmful and you would need immediate emergency response if your appendix bursts.


Symptoms/What to do?-
Most people get their appendix removed before the rupture because the symptoms occur earlier, when the appendix is swelling. The Symptoms are


-First, pain near your belly button,
-Then the pain will usually move down to the lower right
-Vomiting

-Constipation -Loss of appetite -Abdominal pain when you move
If you feel have these symptoms you must go to the hospital. The doctors need time to first diagnose you with appendicitis then go into surgery. Getting your appendix removed is called an appendectomy.

Conjoined Twins

Conjoiiin_Twins.jpeg




What is a conjoined twin? A conjoined twin is a very unique kind of identical twin that is physically attached at birth.
Why are they conjoined? Scientists believe that the twins are conjoined because of a delay in the fertilized egg's division. In regular identical twins the fertilized egg is separated within four to eight days however in the case of the conjoined twins they believe the division does not occur until day 13. So instead of two separate embryos, the twins remain partially attached.
Are there different kinds? Yes! Of course there are different kinds of conjoined twins. When classifying conjoined twins is all depends on where the twins are conjoined then they are given different names . Twins conjoined in the upper body can be Cephalopagus, Craniopagus or Thoracopagus. And twins conjoined in the lower body are Ischopagus, Omphalopagus, Parapagus or Pygopagus. You may notice that there are at the end of all the terms the word 'Pagus' is there. That is because in Greek 'Pagus' means 'fastened'. Other -Conjoined twins are born as often as once in every 40000 births however only once in every 200000 live births-Most conjoined twins only live a couple of hours-Survival rate is between 5 and 25 percent-Conjoined twins can be separated depending on where they are attached -Separation has become much easier and safer over the years and it is now much more successful, at least one twin survives the separation 75% of the time
I was first interested in conjoined twins when I saw a documentary one TLC. These twins were girls that were one body two heads. The documentary was about their 16th birthday and how there were able to get their driver's license!! This is the link for them if you are interested ( just a brief 5 minute summary about them ) .... http://www.youtube.com/watch?v=BkKWApOAG2g
But while I was researching I came across something I think is SO MUCH more interesting and SO cool! This case is on two little girls from British Columbia who are conjoined at the head! It is so amazing! Right now they are still quite young and their mom believes that since they share a brain one can they can see what the other sees, so I am really curious for when they are older and capable to answer these questions for us. conjoined_twins.jpegThis is a link to a 2 minute CTV news report on them - http://www.ctv.ca/CTVNews/TopStories/20101024/hogan-conjoined-twins-birthday-101024/

Achondroplasia (a form of dwarfism) Dwarfism.jpeglittle_people.jpeg
 What is Achondroplasia? Is a disorder of bone growth and is the most common types of dwarfism. Achondroplasia comes from Greek and means "Without Cartilage Formation". Individuals with Achondroplasia still have cartilage however during the fetal development something goes wrong in the process when the cartilage is suppose go in the legs and arms.
How would one come about getting this? There are more ways than one. If the child inherits the defective gene from the parent they will have Achondroplasia. If one of the parents has the dwarfism then the child has a 50% chance of receiving the disorder. And if both parents have it then the chances of the child inheriting Achondroplasia are 75%. Yet most cases of this specific form a dwarfism occurs spontaneously when neither parents have it.
Symptoms? I wouldn't exactly say that there are symptoms for dwarfism considering it is noticeable at birth and doctors will usually be able to tell. You would be able to tell from the following. -Larger head than body -Shortened arms and legs -Prominent forehead -Spinal StenosisIt can also be determined that a child may have this form of dwarfism prior to birth when still in the womb with the help of an ultra-sound.
Other: One with Achondroplasia will reach an average height of 4 feet. The term 'Dwarf' can be offensive. They like to be call 'Little people'

Spiders and Their Webs

sPider_web2.jpg

Why do spiders spin webs? Spiders eat only living things. They spin webs and wait for insects to get caught in them. The web acts as a trap for insects to get caught and also serves the purpose of a home for the spider. When an insect gets caught in the web, the spider will quickly rush to it. Before the insect can even think to get away, the spider rolls it up in sticky threads. The spider then kills the insect with poison to EAT IT!
Why don't spiders get caught in their own web? A spider's web has two kinds of threads in it. The ones that make a spiral or circle pattern are sticky. The other threads are not. The threads that are not sticky are the ones that the spider walks on. It is a truly fascinating phenomenon.
Some Spiders don't spin webs
Flower Spider- Hides near flowers and jumps out to catch flying insects. Wolf Spider- Walks around on the ground and catches insects, as well will get insects that fall into waterJumping Spider- Finds insects by walking around in grass and treesTrap Door Spider- Makes a nest under the ground, then jumps out and catches insects.

Fireflies
firefly.jpeg

What is a firefly? There are about 2000 species of fireflies. Most people are unaware that fireflies come from the beetle family. Most fireflies are winged and are know as glowworms. Where do they live? Fireflies live in a variety of warm environments. They enjoy damp and humid areas. Why do they glow? Fireflies have light organs underneath their abdomen. The firefly takes in oxygen and in special cells it combined with a substance called luciferin to produce heat with nearly no heat. When a female flashes light the male answers by flashing his. It's as though they're calling to each other. This is how fireflies find mates. It is not only the adult fireflies that glow, so do the young ones, and the firefly eggs light up at night too!Other The fireflies light also serves as a defense mechanism that flashes as a clear warning of the insect's unappetizing taste.

Sea Anemones
Anemone.jpg

What is a Sea Anemone? A sea Anemone is a invertebrate stinging polyp that spends most of it's time attached to rocks at the bottom of the sea, or on coral reefs.
What does a sea anemone eat? A sea anemone is a carnivore and eats other fish that pass by. A sea anemone wait for a fish to pass close enough by so it can trap it and take it into its venom filled tentacles!
Are there different kinds? Yes, there are 1000 + various different kinds of sea anemones found throughout all the oceans! They can vary from 0.5 inches to 6 feet!
Can a sea anemone move? Yes, some but not all sea anemones can move. ( like the video we saw in class ). Some will also attach on to something like a hermit crab and hitch a ride!
Other- *Sea anemones can open and close. the sea anemone has tentacles that look like flower petals. It uses the tentacles to catch food. The sea anemone pulls the food into its mouth with its tentacled and closes itself up. Then it opens again. The sea anemone also closes itself up when low tide leaves it out of the water or when an enemy attacks. *Some species of sea anemones can live 50 years or more!

Atlantic Puffins



PUFFIN.jpg

Considering I have some Newfoundland blood, I thought it would be interesting to do a post on one of my favourite birds! THE PUFFIN!
What is a puffin? The Atlantic Puffin is a bird that spends most of its life at sea.
What do Puffins eat? Puffins eat small fish, they eat small fish such as seal eels and hearing. How they eat is also quite interesting. Puffins go underwater to catch pray, puffins can stay underwater for up to a minute and can dive up to 200 feet under!!
Super Dooper awesome facts about PUFFINS!- Puffins (when flying) can flap their wings up to 400 times per minute- After the female lays an egg it takes about 42 days to hatch - After hatching it takes about 50 days for the baby Puffin to learn to fly and can live on their own- From April to August puffins join together in breeding colonies- The average puffin lives for about 20 years. The oldest recorded puffin was 29. - In the winter the beak on the puffin fades, as does the bright colour of their feet- The scientific name for Atlantic puffin is Fratercula arctica
- The Atlantic puffin is the only species of puffin in the Atlantic. In the Pacific there are 3 species

Why do our eyelashes fall out?
eyelash.jpeg

Just a few years ago, I always found myself with eyelashes on my paper at school, on my cheek, and the worst, in my eye! There was a point where it seemed like I had an eyelash in my eye at least 3 times a week! And they are not the easiest thing to get out. (I have become an expert at it though!)
So why do our eyelashes fall out? Well, after I started feeling like my eyelash lost had gotten... well out of control I asked my eye doctor, and he said that is was completly normal to loose eyelashes and new eyelashes are always growing and I had nothing to worry about in my case. Although, I did some research and there are aswell other reasons that one may find they loose more than necessary amounts of eyelashes. It is possible that there are medical reasons, or perhaps could be the mascara you are using. Other causes may include- Stress, an autoimmune disease that causes hair loss, allergies, constant eye rubbing or nutritional deficiencies. What you may want to take into account- Nutritional deficiencies can be easily helped by eating a more well-balanced meal. You can switch makeup products if it is due to the brand you are currently using. And if you think it is really bad, do not be shy to ask a doctor, or someone that may have the answer you are looking for. In my case a few years ago, it could have simply been because I was stressed.Some tips from me!- -Whenever there was a tricky eyelash I couldn't get out of my eye, I would fill up my CLEAN sink ( make sure it is clean) with water, dunk my head under and open my eyes! You usually only have to do this if the eyelash is seriously lodged somewhere.-Always, Always ALWAYS make a wish on your eyelash! (Please tell me you have heard of that? When you have an eyelash you blow it away and make a wish... I am not making this up)-Now, the next time you find an eyelash on your cheek please do not panic. Don't let this post scare you, or make you think you have some sort of eyelid cancer or disease. Like I said, loosing eyelashes is normal and is supposed to happen.

Chickenpox ChickenPOx_comic.jpg
If you have ever had the chickenpox, you can agree with me when I say they are not fun! Not fun at all!What are chickenpox?- Chickenpox is caused by a virus called varicella zoster. What happens if you get chickenpox?- Well, like you have most already probably heard, you get quite itchy. But at first, you may have cold-like symptoms. You could have a headache, runny nose, fever etc. Somewhere between one and 2 days after your cold symptoms, you will start getting the rash. The number of pox differs from person to person. How do Chickenpox spread? Chicken pox spread very easily, they can spread by direct contact from on to another, you can get them from touching a blister or the fluid inside the blister, the virus enters the body through the nose or the mouth, it can spread through the air. I remember when I got the chickenpox, my cousins that my sister and i spend the whole summer with at my cottage had them, and we thought that we were invincible and were not going to catch them even though our parents warned us we would! And sure enough all four of us cousins had them at the same time so it kind of worked out because then we could all hang out! But it was interesting after doing this research to see just how easily they can be spread! I read on one website it quoted " The only way to stop the spread of the virus from person to person is to stop the infected people from sharing the same room or house, which isn't practical."



Symptoms- Fever Within 1-2 days Starts with red spots and then turns into fluid-filed blisters Some have only a few blisters, some can have up to 500!!
