Science Fact of the Month – October 2010

Sunday, October 31, 2010 @ 09:10 PM
Abbas Karimjee[ Administrator/ Owner]

This month, we will examine  the issue of pathogens.

 Pathogens: A pathogen is an infectious agent which can cause  illness  through genetic altercation.

Reference:http://dictionary.reference.com/browse/pathogen

Various examples of pathogens include viruses such as the Spanish inflienza in 1918, where the victims were healthy young adults.The illness lasted for over two years and  was responsible for over 50 million lives.

 Another example of a pathogen, is the  Sars Virus. Take look at  a photo of the process in which this virus  used to spread, directly below.

What other examples of pathogens do you know ? Share them in the comments section with us!

Science Fact of the Month-July 2010

  In follow up of  last month’s fact which covered The Theory  of Natural Selection, we will now look at the Theory of Social Darwinism [ Survival of  the Fittest], which misused the theory of Charles Darwin’s, Natural Selection by applying it to  the social and political world.

 The  Theory of Survival of the Fittest was first coined by  English philosopher, Herbert Spencer.  The theory involved  various  nationalities and  races believing that they were superior in strength and intelligence  and  thus  possessed the right and   obligation to dominate over  the  other “inferior” races, who were believed to lack these qualities. They believed that these “inferior” races would ultimately be conquered  or replaced because of their “natural disadvantage.”.  Those who  accepted this are known as Social  Darwinists.

Although this theory is no   longer accepted by reputable Anthropologists today, there are many  unjust  examples from the past which demonstrate this behaviour. One such example is the cruel treatment of Aboriginal people in North America during the time period.

 Do you have any other examples  to share? Share  them in the comments  section.

Science Fact of the Month – June 2010

Did you know about the Theory  of Natural Selection? This month ,  in our  one – hundreth post, we cover the premise of this   scientific theory.

 The theory of  natural selection which was formed by Charles Darwin is that  no two  members of  the same species are exactly identical. This is due  to differences such as biological inheritance and   the  ability to partake in environmental adaptation. Over time some members  of a species will  develop  physical features which enable  it  to survive while others will not and thus die. Those who survive  will procreate  ,  ultimately creating a new  species.

 Proof to support this theory is how  recent genetic studies link all of us back to a common African origin. This shows that we have evolved, thus  explaining why we   have a variety  of  different   physical  features/ looks  and cognitive abilities.

   What are your thoughts  on the  theory?Do you have any  additional proof  to support it?Do you have reason to disagree with it? Sound off in the comments section below!

Science Fact of the Month- May 2010

With LOST just having ended   last week,it  seems appropriate to have  this month’s  Science Fact of the Month tie into the series. We will therefore be covering electromagnetism

The basic premise of  electrical magnetism  is that  electricity  is  being transported through  a wire . By being transported through  a wire, a magnetic shield is created in the surrounding area.

Some examples of objects created by  electromagnetism include  tape drives, speakers, motors, e.tc.

It should be noted  that virtually all movement/ actions are  due to electromagnetic forces which  react on charged protons and electrons.Remember,  that this also includes the pushing and pulling effects  when an object is being moved.

As LOST viewers are aware, the original  Oceanic flight 815 crashed due to a spike of electromagnetism  which was not contained as the hatch responsible for doing so was not  being monitored by its  keeper, Desmond Humes.Take a look at the scene of the crash directly below.

Enviornmental Tips – Preventing Water Pollution

Monday, May 10, 2010 @ 06:05 PM

Here are 5  measures which  can be  easily undertaken  to help prevent water pollution

 1.  Help conserve water by  shutting the tap when you  do not require  it to remain  operational. For example,  if have wet your brush then you should  keep the tap off while you are brushing instead of letting it run the entire time. This will help prevent  water from being wasted and  reduce your monthly hydro bill.

 

2.Do  not   dispose of items such as     paint or oils down the  drain or toilet.Appropriately place  such items in the garbage or recycling cans.

3.Only operate the dishwasher when it is full or you are sure  that  no further dishes will need to be loaded  later on. This way  you can  do fewer washes which will  not only conserve  water  but also  reduce your hydro bill and save  time. Also, if you are washing  your dishes, ensure that  you are not using any soaps which contain the contaminating  phosphates.

 4. Avoid littering  bodies  of water such as  ponds , lakes,  or oceans. Instead  you should   dispose of  uneeded items  in  the garbage  cans or recyclying  boxes.

5.Avoid using an  excess of fertilizers and pesticides as such    substances can contaminate water in the environment as they  can easily enter local runoffs during rainfalls.

Did you know that there are over  4000 ingredients in a cigarrette besides tobacco?Many of these are poisons, intoxicants and other dangerous subratances whih can severely damage  one’s body. Take a look at some of these directly below!

Ammonia  A household cleaner

Butane – gas  , used in lighter fluid, affects nervous system

Cadmanium –  used in batteries, damages kidneys and lier

Cyanide – deadly poison

DDT- A banned nesticide known to cause  exremele damage to the digestive system of those in higher tropic levels [  humans are esppecially at risk since we are  apart of the highest tropic level!]

Science Fact of the Month – March 2010

Did you  know that nitrites  in drinking water can permenantly damage or even kill infants? Read  our full overview further below.

High levels of nitrates in drinking water pose  a threat especially for young human infants  because humans and other animals usually have a  bacteria that converts nitrates into nitrites  within the large intestines.While adults are protected from  the harmful effects of these bacteria[since the  digestive system of human adults is highly acidic], the stomach of an infant being  very low in acidity , lets the bacteria move up in the stomach where nitrates are subsequently converted into nitrites.This is a serious issue as nitrites pose a serious threats to  creatures which contain hemogobin[ such as humans] in their blood as nitrites can  attach themselves to the  hemogobin  in  the blood of infants .As a result of this attachment, the infant’s body is unable to receive a proper  supply of oxygen to its  tissues.Significant permenant damage can result.

   Remember, that we welcome your Science Fact of the Month. Feel free to send it to us   at blogmanagement@ymail.com All submissions should include a fact with atleast a couple of sentences which provide supporting   details on the fact. Including a reference is  encouraged.

Science Fact of the Month – February 2010

Here are 2 disadvantages  with respects to  applying pesticide on crops.

-Thepesticide kills by  operating as nerve gases,acting by preventing  electrical messages to the  from travelling  from the brain to muscles that  control the breathing or limbs.This not only  kills the pest, but also  other larger   animals[birds, reptiles, birdsm amphobians and fish] who have a  similar nerve actions.

-Breaks down quickly in the  soil, so  the pesticide  must be applied to  crops more often.This means that a great deal of money will have to be spent on the pesticide as an abundant supply will needed.Also, appplying the pesticide on a more regular basisrequires a lot of time.

Do you know of any other disadavntages?Share them in the comments segment further below!

 See you next month!

Science Fact of the Month November 2009

Did you know that the addition of nutrients to an ecosystem can be   quite deadly?

An excess of  nutrients  in fertlizer rerun off from farms can cause  a  signifcant growth of algae  causing an algal bloom.Eventually these algae will die and decomposing bacteria, will, in turn   break down the algae .Unfortunately,  the decomposing bacteria requires  a lot of oxygen to do this.Since they are depleting the levels of oxygen , fish  and other aquatic `creatures  begin to die .Not only can severe ecological damage occur, but also   the decline in fisheries can cause   a negative effect on the economy.

See you next month for more Science.

Science Fact of the Month-June 2009

Tuesday, June 30, 2009 @ 11:06 PM

Global  warming is the increase of the average temperature of the earth’s atmosphere.This increase results in drastic negative climate changes.Such changes are  usually initiated as a result of  the greenhouse effect.

The greenhouse effect is  when the earth’s atmosphere  traps radiation from the sun due to  the presence of various gases such as Carbon dioxide, methane and water vapour whichallows the atmosphere to absorb   heat radiated from the surface.

Be sure to take a look at  our Enviornmental Tips post in theJuly 2009  icon on the sidebar to find out  various initiatives which can easily be  launched to prevent global warming.
