The Ways Science Helped To Bring A Positive Change In World Even After Many Ups & Downs In This Year.
In year 2015 world saw many ups and downs from furious natural disasters to terrorism from a step to end global warming to free internet initiative.Whole world witnessed many good things as well as bad things and majority of those good things were because of innovations in field of science.The key player in those positive developments was science.Here I will mention those scientific researches and innovations which helped to cool down little bit the blazing fire of negativity across the globe.
1."SWITCHING OFF" CANCER CELLS GROWTH USING PLEKHA 7 PROTEIN.
Scientists in mayo clinic Florida did incredible job when they programmed cancer cells back to normal cells.It was like a new hope for current cancer patients and for generations to come.It was first time when aggressive cancer cells in breast,lungs and bladder were moved backed to normal condition.Scientists believe this technique can be used in future to treat tumors which can save patients from expensive and painful chemotherapy.Scientists discovered that they can switch on cancer by removing microRNAs and stopping them from producing protein pelkha7.They figure out this process can be reversed to stop cancer cells from producing by injecting pelkha 7 and microRNAs,It is till not that enough to fight cancer but still it solve a lengthy biological puzzle and would play a major role in other researches related to cancer.It is simply another big step towards solving cancer mystery.
2.GREEN TEA A GUARD AGAINST ORAL CANCER
In January of 2015 a research was published by Pennsylvania state university food department.According to researchers compound epigallocatechin-3-gallate-EGCG found in green tea can kill oral cancer cells without causing any damage to normal/healthy cells.Joshua lambart associate professor of food science revealed that this compound triggers a cycle in mitochondria which kills cancer cells.He said "EGCG is doing something to damage the mitochondria and that mitochondrial damage sets up a cycle causing more damage and it spirals out, until the cell undergoes programmed cell death." he further said "It looks like EGCG causes the formation of reactive oxygen species in cancer cells, which damages the mitochondria, and the mitochondria responds by making more reactive oxygen species .The researchers said EGCG did not cause any damage to normal cells infact it increased their protective capabilities.The next step would be to conduct this study on animals if it will be a success then this process could be used in future to treat cancer.
3. EBOLA VACCINATION
Ebola a virus or disease which can be life threatening created a huge buzz in start of 2015. In July Canadian scientists at national microbiology laboratory in Winnipeg discovered world's first effective Ebola vaccination.This vaccine is named VSV-ZEBOV .It is being made by pharma giant Merck.WHO representative dr.marie paul kiney said"it suggests it works,it works pretty quickly and it works well."Further interim analysis was conducted by monitoring board which concluded the result that vaccine was working.It is also commercially being made by New link Genetics. It was the major scientific breakthrough which bought hope and new energy in people regarding Ebola.All the hardwork of scientific institutions worked.
4. MAN WITH PARALYZED LEGS WALKS AGAIN
Man in USA,California started walking again.Man in center of the picture suffered a accident and in result of that his lower body was completely paralyzed because of injury to spinal cord.As reported he walked a distance of 3.5 meter after being fitted with an electrode cap which picks signal from brain and send it wirelessly to computer which decides according to the wave produce that whether he wants to stay still or walk and then sends a signal to belt which triggers muscle movement .It is a difficult process because you have to learn to how to generate those signals in your brain and you should have tone muscles to move your legs and learning the process of moving your leg one after another.Still its a small light of hope in darkness and this method can be used in future to ease lives of people with lower body paralyzed.
5. "IMAGINARY MEAL" PILL
Scientist dr. Ronald Evans developed a imaginary pill which tricks our body that we have eaten lot of food and now its time for clean up.It is possible by drug fexaramine which releases protein farensoid x receptor which plays role in releasing of bile acid from liver and digesting food.Scientist said this drug doesn't dissolve in blood like other fat loss products which are based on caffeine and other appetite suppressants which results in crashes.That's why this drug would not give crashes.This experiment was conducted on fat mice on period of five weeks.In those weeks mice stopped gaining wait and cholesterol and blood sugar level remained low and temperature was up which means her metabolism was firing up.Clinical trials are likely to be conducted on humans if trials would be a success then it could play a major role in fighting obesity.
6. WATER FOUND ON MARS
In last few months of 2015 NASA confirmed that water flows on today's Mars.Back ago it was thought Mars was once a planet with water but later it was frozen. Using imaging spectrometer on MRO researchers found evidence of water they said darkish streaks appear to ebb and flow over time.They darken and appear to flow down steep slopes during warm seasons and fade away in cooler seasons.These streaks appear when temperature is greater than -10 degrees fahrenheit. Lead scientist for NASA's mars exploration program said
These were those researches or developments in field of science which kept the hope for better life alive.When whole world was listening bad news from natural disasters to terrorism to economical crisis.Credit goes to all those scientists who participated or conducted these researches in order to improve human life.

Lead scientist for NASA's mars exploration program said
It took multiple spacecraft over several years to solve this mystery, and now we know there is liquid water on the surface of this cold, desert planet.It seems that the more we study Mars, the more we learn how life could be supported and where there are resources to support life in the future.”While another evidences which NASA found on Red planet was the hydrated salts which lower the freezing point in liquid brine.Just like it is found on roads in earth causes snow and ice to melt quickly.The search for life on Red planet continues with possibilities there will be life after few years on Mars but still all these researches are in its initial stages and it's not possible to draw conclusion.
These were those researches or developments in field of science which kept the hope for better life alive.When whole world was listening bad news from natural disasters to terrorism to economical crisis.Credit goes to all those scientists who participated or conducted these researches in order to improve human life.
