Global warming

               Hello my name is Sidney Gomez, and I am making this article, because I want to know more about the global warming. Now with the clases that I am having with Mr. Wilkinson about the different cycles that affect the abiotic, and biotic factors, and life I am getting  more interested in the global warming issue.
              Global warming is one of the problems that seem more difficult to solve. Our leaders are making some solutions for this problem, BUT  those solutions are not helping too much. Conferences are being made, so presidents can get a solution, but that ideal soulution is far away to be discovered.
               But if YOU don´t do anything, huge ice capes are going to melt. This means that the biggest porcentage of drinking water will mix with the 97% of salt water that we can´t use in many things.
Think about the animals that die of deshidratation, the plants that help us get food and get oxygen, think about the next generations that will come after you.
               I invite everyone that reads this to go to this link, so you can see how the north pole ice cape is dissapearing. this link http://topics.nytimes.com/top/news/science/topics/globalwarming/index.html#
               I used this link( the same as the one as the one asthe one over this  one) http://topics.nytimes.com/top/news/science/topics/globalwarming/index.html#
                  These links were used to inspire me.
      
               

tips for surviving radiation emergencies

Nuclear or radiation emergencies occur when nuclear material or radiation is released or exploded during an accident or attack. An explosion can cause blinding light, heat, fires and dangerous radiation. Now I am going to tell some tips, so you don't die because radioactive material 

- First try to go to the opossite place that the wind is blowing, if possible drive with closed windows

- Find shelter, if below the ground better, but anything that can be used as a shield can help you from being radiated.

-When you arrive to your shelter :Turn off all furnaces, air conditioners and fans.Close vents. Close and lock all doors and windows.Take off your clothes and put them in a plastic bag. Seal the bag tightly.Take a shower or wash your skin and hair well with soap and water.Put on clean clothes.

-watch television for new updates, and if you are hurt call for a doctor.

- If you are far away from the place were the radioactive material is getting out, look for updates and call officials or authorities, so they can tell you were to go.

knowledge of cancer

Whales are bigger than us, that means that they have many more cells, which can mutate harmful or helpful, so they have more possibilities to get cancer and tumors by mutating.

Whales can have cancer, but the probabilities are not so big like in humans, because they have a high level of materials and chemicals that help them to retract it, so after some big calculations, scientists know that 100 out of 5000 whales can develop cancer. Now scientists are looking for those chemicals and it's functions, so they could use them in humans

Summary: Many whales could die from cancer like humans, but most of them don't die, because they have some chemicals that save them. Now scientists are looking for those chemicals, to try to use them in humans.

I liked this article, because it's good that most of the whales don't die because of the cancer

Looking for a better cure.

Tuberculosis , is more prevalent in the world today than at any other time in human history. Mycobacterium tuberculosis, the pathogen responsible for TB, uses diverse strategies to survive in a variety of host lesions and to evade immune surveillance. A key question is how robust are our approaches to discovering new TB drugs, and what measures could be taken to reduce the long and protracted clinical development of new drugs. The emergence of multi-drug-resistant strains of M. tuberculosis makes the discovery of new molecular scaffolds a priority, and the current situation even necessitates the re-engineering and repositioning of some old drug families to achieve effective control. Whatever the strategy used, success will depend largely on our proper understanding of the complex interactions between the pathogen and its human host. In this review, we discuss innovations in TB drug discovery and evolving strategies to bring newer agents more quickly to patients.So we are looking for a cheap and successful medicine that cures tuberculosis easily.
