require more efficient sources of power. At the forefront of research for these power sources are hydrogen fuel cells. This power source takes in the most abundant element in the universe‚ Hydrogen‚ and yields immense power without combustion or pollution. The three aspects of this scientific breakthrough are the fuel cells‚ hydrogen production‚ and hydrogen storage. Fuel cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something

Points‚ and Plan “Should regulations regarding the use of cell phones while driving be standardized?” On December 13th 2011‚ the National Transit Safety Board called for a complete ban on cell phone use while driving‚ arguing that even hands-free phone use was distracting and dangerous. However‚ two weeks later‚ U.S. Secretary of Transportation‚ Ray LaHood‚ said he would not endorse a ban. His justification was simply that hands free cell phone use was “not the big problem in America”‚ which in my

to a phone that could be taken virtually anywhere. He called it the cell phone. The cell phone today doesn’t share anything more than its name with the original Cooper model from 1983. However‚ the cell phone remains just as much of a groundbreaking device that divides people in very powerful ways. There are some who strongly back the product and those who stand strongly against it with very valid reasons. At times‚ the cell phone serves as a powerful communication device for humans and as a

TREATMENT OPTIONS There is NO cure for sickle cell disease‚ although new stem cell research is promising. Bone marrow transplant is a potential cure‚ however finding a matched sibling donor is difficult. Therefore treatment is primarily focused on management of symptoms and prevention of pain episodes. Hydroxyurea (a chemotherapeutic medication) is the only recognized treatment option for the prevention of vaso-occlusive crisis in SCD. It is a prescribed drug for adult patients

Diffusion in Cells Isabel Zak Question: How does the size of a cell affect the distribution of chemicals throughout the cell? Hypothesis: The larger the cell is‚ the more difficult it will be for the chemicals to reach the centre of the cell‚ and diffuse throughout it. This is because there will be a higher surface-area to volume ratio in the larger cells‚ making the centre of the cells further away from the surface. Therefore‚ when dipped in sodium hydroxide‚ the larger cells will not be

CELL PHONE CLONING Abstract You might have read news of the cloning of sheep or cattle with amused interest. But how would you feel if somebody `cloned’ your mobile phone? Technology is finally rearing up its dark side. Along with the proliferation of technological innovations‚ this era also marks the birth of the new-age IT criminals in a big way‚ with the latest technology fraud being cell phone cloning. Cell phone cloning is a technique wherein security data from one cell phone

Sickle Cell Anemia Sickle cell anemia is an inherited blood disease. The word anemia is defined as meaning that the blood does not have the required number of red blood cells. These cells take on a crescent shape‚ which is where the disease takes its name from the abnormal sickle shapes of the cells. It is commonly found in people from Africa‚ the Mediterranean region‚ southern India and the Middle East. “This disease of the blood was first discovered in 1910 in a black college student from the

Basal Cell Carcinoma Danielle Robbins Abstract This paper briefly describes basal cell carcinoma. Several scientific studies and articles are referenced to further present the causes‚ symptoms‚ tests‚ treatments‚ and prognosis of basal cell carcinoma. Also included in this paper are the different types of basal cell carcinoma and the populations that are affected. Basal cell carcinoma (BCC) is a skin cancer that starts in the epidermis (Medline Plus‚ 2012). The Skin Cancer Foundation defines

Cell Phone Technology The cell phone technology that is ever changing by the day was scientifically invented and born back in the early 1980’s. Science was the main key to the birth of the cell phone which was put together by the Motorola Company who today is still making cell phones. Before the cell phone came out the car phone was the first mobile phone which were very large and had to be hooked up to a briefcase which supplied the power for the mobile phone. Science was the utilized to create

bacteria we all have in our mouths and on our bodies. Life is indeed a gift. Every life that comes into this world is made up of cells‚ life of humans‚ plants‚ and animals. I know that to understand the nature of life we must first comprehend the cell‚ its parts‚ and organelles. There are two different types of cells‚ including prokaryotic and eukaryotic. Living bacteria is an example of something that contains prokaryotic cells. Eukaryotic cells are in just about everything‚ all humans and all animals
