Prevention: Coffee Lowers Risk of Prostate Cancer, Harvard Study Says

A new result has shown that if people drink coffee they're less likely to have prostate cancer.  Harvard students did research on how much people drink coffee.  They found out that people who drink 6 or more cups of coffee have a 20% less chance of having prostate cancer.  Heavy coffee drinkers were 60% less likely to get lethal form of the disease than the non-coffee drinkers.  This study did not measure how much caffeine is put in the coffee or whether it is not caffeinated, rather the cups drank.  By drinking coffee you also have a lower risk of getting Type 2 Diabetes.  This study isn’t telling people to go crazy with drinking coffee, rather just drink it 3 to 4 time a day, or more just not crazy like 30 cups.

Why Do I Get Acne!!!!

I have acne and I try every possible way to get rid of them.  I never really understood why teenagers got pimples, but by reading this article I’ve finally cracked the code.  Anyway, I learned a few tips to keep my skin healthy, and to have fewer pimples.  For example, I learned to watch my face often, not just twice a day.  My cousin told me to wash my face with cold water, but according to this article I should wash my face with warm water.  I also learned a few more terms from this article like, sebum, which is oil that lubricates your hair and skin.  Another term I learned is sebaceous glands which are also called oil glands.

Rocket Lab

My partner, Palavi and I conducted an experiment in the rocket lab.  We learned a lot about gravitational potential energy and elastic potential energy.  Gravitational potential energy is the energy stored in an object as the result of its straight up position or height. The energy is stored as the outcome of the gravitational pull of the Earth for the object.  Elastic potential energy is the energy stored in the rubber band as the result of its stretching.  For example, when we stretched the rubber band two centimeters, (elastic potential energy), the height that the straw shot in the air was fourteen meters.  So to find the gravitational potential energy we used the formula mass x Gravitational acceleration x height.  We plugged in the numbers for the formula 2 kilo grams; being the weight of the straw, 9.81; the gravitational acceleration and 14 meters; being the height.  Al together the G.P.E was 28 millijoules.  The more elastic potential energy you have, the more gravitational potential energy you’ll have.  For example, when Palavi and I stretched the rubber band to 3 centimeter, the height was 32.3 meters high and the gravitational potential energy was 64.6 millijoules.    

                Palavi and I probably measured the height of our rocket wrong.  Because, when we stretched the rubber band back to 2 centimeters we got a height of 14 inches.  But when we stretched the rubber band back to 3 centimeters we got a height of 32.3 millijoules.  Palavi and I most likely measured the height of the rocket wrong.  To fix this problem we could start this lab over and accurately measure the height of the rocket once more.  Making sure our data is as authentic and realistic as possible.

Case Study 3 Trisomy 13

Dear Mr. and Mrs. Close,

Dr. D and I have examined your child’s karyotype very closely.   Karyotype is a test we use to check your child’s abnormalities.  To do this test we line the baby’s chromosome and examine the chromosomes.  We check for diseases, and by doing this test we are able to determine the sex of the baby.  In this case Mr. and Mrs. Close I’m pleased to announce that Mrs. Close will be delivering a girl.  While we were determining the karyotype we found that your daughter has an extra copy 13 chromosome.

Having an extra copy of chromosome 13 is a rare disease called Trisomy 13 or Patau Syndrome.  Trisomy 13 is usually due to an egg cell, or, rarely a sperm cell which is formed containing one copy of each chromosome but an extra copy of chromosome 13.  Now rather the baby having 23 pairs of chromosome she has 24 pairs.  Once that egg is combined with the sperm which contains 23 chromosomes, the baby gets 47 chromosomes in the cell of their body rather than the usual 46.  Patau Sndrome also is more common is women who are pregnant at an age over 35.  Trisomy 13 can also occur if you have a family history of Patau Syndrome.  There are many physical defects because of Patau Syndrome.  A few of these defects are; Holoprosencephaly, polydactyly, flexion of the fingers, rocker-bottom feet, facial clefting, neutral tube defects, and heart defects.  These disorders are naturally long term affects.

There is no treatment for Trisomy 13 except for polydactyly, which is cured by surgery.  Sadly, if a child has Patau Syndrome she’ll pass away in fewer than three days.  The only thing you can offer your child is comfort and stay with her as long as you can.

As I said before if you have a history of Trisomy 13 you’ll have a higher risk of producing a Patau Syndrome.  Also if you’re over 35 years old and have a child you also have a higher risk of delivering a child with Trisomy 13.  Trisomy 13 is a very rare disease.  It occurs in about 1 in 5,000 to 1 in 12,000 in babies and usually common in baby girls.  I’m sorry to say if you were to have another child it’s a 50, 50 chance that the next child would be diseases with Patau Syndrome.

I’m sure you’ll spend time with your new daughter for as long as you can.  And I’m a 100% sure that your daughter will bring happiness and joy to your life as long as she’s alive.  Mr. and Mrs. Close I’m sure and positive you and your daughter will be a great family for as long as she survives.

Sincerly yours,

Doctor Irfan

Tooth Pick Fish

Examining alleles of fishes can be very important when they are able to adapt to their surroundings by camouflage.  To begin off the first generation in the gene pool contained of two heterozygous pairs of green and red fish, two homozygous pairs of yellow fish, one homozygous red, four orange, and three homozygous green fish.  When all these fish mated they produced offspring equaling to 58.3% green, 16.6% red, 16.6% yellow, and 8.3% orange.  Since the yellow fish could not adapt to the gene pool, they died going in the morgue, which decreased the population by 16.6%.  During the second generation of offspring there were 50% green, 20% red, 0% yellow, and 30% orange.  Then during the third generation the total color of offspring was 60% green, 20% red, 10% yellow, and 10% orange.  And lastly, the fourth generation contained of 55.5% green fish, 33.3% red fish, 0 yellow fish and lastly 11.1% orange fish.  As you can see all the colored fishes have decreased except for the green fish.  This happened because the green fish was dominant making its population increase.

During the fourth generation a huge disaster occurred.  Humans started littering the gene pool, causing the seaweed and algae to turn different colors.  Now that the seaweed and algae have changed colors the green fish are easily able to be seen and eaten by their predators, while on the other hand the red, yellow, and orange fish are able to camouflage by sand and rocks.  Now the only survivors are red fish and yellow fish.  There are 11.1% orange fish and 33.3% red fish remaining.  This disaster shows that by humans polluting the earth they can cause the dead of many organisms.  If the environment changed in any way, it could change the way fish live, by the fish adapting to the environment.  For example, if the littering human did to the gene pool destroyed seaweed and killed algae many fish could die including the green fish.  As you can see many fish adapt and survive by camouflaging while others easily spotted by their predators.   

The Heart!!! 1/30/11

1/30/11

The heart is a very important organ in your body.  Though I didn’t read an article I still learned various facts.  For instance, people who study the heart are called Cardiologists.  Did you know that that the heart is made up of four chambers; the left atrium, right atrium, left ventricle and right ventricle?  After reading this article of the heart, I finally learned more about this unique organ, I revealed the mysteries and secrets of THE HEART!  Heart attacks can cause scar tissue to form amongst normal heart tissue; this then can lead to further heart problems or even heart failure (cited in the interesting facts linked).  Ever wondered why you have veins, well you’ve got veins because the veins carry blood to your hearts.  There are different veins that go through different passageways.  I believe the previous article I read though was more interesting than the heart.  I believe the eyes have more mysteries than the heart, which makes the eyes more interesting.  There are also 4 valves in the human heart this is so that the blood goes only 1 way either in or out.  Did you also know that an electrocardiogram (ECG) is a machine that checks the electricity going through the patient’s heart?  If the machines lines are flat that means the person is dead and if it spikes up and down the person’s alive.
