The article I had the pleasure of reading indicates a growing problem caused by our current surroundings and the human race’s evolution. In fact, our ancestors spent most of their time in the outdoors and with the large presence of fresh air and natural lighting, their senses developed in a healthy way. Today, because of technology, time spent indoors by humans is significantly more than what it used to be, causing modifications to our vision.

In summary, the text says that there are a lot of benefits that exercise has on our brain. With many researches, they found that exercises have an impact on the memory, the cardiovascular fitness, and on the cognition (ability of acquiring knowledge). It also says that sports with teams were more popular; people choose team sports instead of free gym membership and home-based programs. The text explains that there is still a lot to find about the connection between the exercise and the brain.

Briefly, human cancer is traditionally known to occur from heredity or environmental sources, but researchers found errors in the DNA replication of many healthy cells that has an effect on cancer and they called that factor ‘’R’’ or random mutations.

Did you know that climate change does not only affect icebergs in Antarctic but also river in Europe? The article "Climate Change Is Altering Flood Timing in Europe" written by Michelle Hampson is just about that. A lot of long term studies have been done since 1960 to compare and understand flood timing. Earlier flooding has been proved by analysing all data collected from different hydrometric stations in Europe.

Lately, I’ve read a news about gravitational waves. Last August, two neutron stars entered in collision which created a huge explosion that resulted in many gravitational waves and radioactive material.  The first waves ever detected were in 2015, but with the last events, scientists have been able to detect for the first time light from a gravitational wave source.  They also could observe the effects of that encounter between two neutron packed stars. At the moment it was detected, astronomers from all around the world focused their equipment on this extraordinary phenomenon.

This week, I saw a very interesting article about the DNA replications causing cancer on this website: https://www.aaas.org/news/random-errors-dna-replication-play-major-role-cancer. It contains a lot of information linking random mutations in the dividing of cells, named R mutations, with different types of cancer. This article explains clearly how R mutations are made and how we can prevent them.

A few days ago, I read an article on the website of the American association for the advancement of science. It was talking about changes in the Arctic Ocean. Since 2002, a team of scientists from the University of Alaska Fairbanks, led by Igor V. Polyakov, is making observations in this part of the Earth. The researchers set buoys to collect data during the different seasons and they compared them with those they take with satellites. They notice that the Arctic Ocean starts to have more common features with the Atlantic Ocean.

As the article says, bats are known for their way to fly in the dark. They have the abilities to avoid obstacles while navigating even if they can't see where they are going. The bats send high frequency sounds which helps them to evaluate the obstacles. One day, Stefan Greif was studying the way bats use to go from place to another. He realized that bats had tendancy to collid with vertical surfaces. He decided to go further and do an experience. The results confirmed that bats have difficulty to recognize vertical surfaces.

Our senses are undeniably of the utmost importance in our lives, since they allow us to connect not only with our environment, but also with each other. It is well-known that over centuries, human’s sight has evolved as we started living in a less primitive state. In fact, according to researchers of the 2017 AAAS Annual Meeting in Boston, all three of our sight, smell and taste change depending on the environment we’re in. It was said that although sight problems are genetic, things like artificial lights and “near-work task” affect noticeably our visual acuity.

The article Science Makes Its Voice In Washington and Beyond written by Anne Q. Hoy is about the March for Science that took place on April 22nd 2017 in the streets of Washington DC. It wasn’t the only March for Science that happened on that date; actually, similar marches happened all over the globe, but, for this article, the author focused only on the Washington’s one. In the column, Hoy mentions that more than 50 speakers all linked nearby or far from science stood up and spoke about the importance of science in our society in front of a large auditory of science lovers.

The main result of this article is that “nearly two-thirds of mutations in human cancers are attributable to random errors that occur naturally in healthy, dividing cells during DNA replication.”  Before this result, the scientific community believed a much bigger part of the DNA mutations were cause heredity or environmental source. According to one of the researcher, the implication of the R (random) mutation was underestimated he believes that their result will increase the attention given to it.

Recently, I read an article about the increase of the death rate caused by opioids in the United States. Experts consider this phenomenon as a crisis that is mostly due to the use of heroin and fentanyl. Fentanyl is a synthetic drug mostly made in China that is 30 to 40 times more powerful than heroin. This drug is not meant for human consumption but for pain reliever on big animals and this is why it causes so many death.

An earthquake is considered as a violent and sudden shaking of the ground. It destroys everything in the area and greatly damages the infrastructure of buildings. For the most part, thousands of lives are in danger during and after its activity. Scientists created an earthquake forecasting model to reduce the damage input of this disaster. They made a research about 40 different earthquakes from all around the world and tried to construct a model from their observations.

I read an article called Neuroscience maps new ways to treat human fear and anxiety written by Anne Q. Hoy on October 24th 2016. This article was about the paper published in September by Joseph LeDoux, professor of science and director of two institutes at New York University, and Dr. Daniel Pine, chief of the National Institute of Mental Health Intramural Research Program. In short, they say that fear and anxiety occur in two different sets of neutral circuits that react differently to threats instead of occurring in a single “fear center”.

As the article say,  the shifting time of flood is an important consequence about the climate changes in Europe. Worldwide it is one of the natural hazard that affect people the most. About $104 billions is lost globaly.  It says that the climate change affect different regions by many ways depending on their position on the map. The North-Eastern Europe is affected earlier by the spring snowmelt. The north sea region have their winter storm later in the season, the mediterranean cost is affect the same way and the west of the Europe have the moisturizing of their soils earlier.

Nowadays, it is well known that the level of pollution is rising everywhere around the world; water pollution in peculiar. This important resource can also be contaminated by many types of bacteria. However, there is a solution to this problem which is presented in the article entitled « Seagrass Reduces Marine Pollution and Disease ». According to a recent study ran in Indonesia, ocean seagrass meadows, which are made of flowering plants growing in saline environments, have the capacity to reduce bacteria unhealthful to humans and marine organisms by up to 50 %, naturally.

I recently read an article of the American Association for the Advancement of Science (AAAS) about an advancement in biottchnology, named: New Artificial Chromosomes Set Stage for First Complex Synthetic Genome, written by Meagan Phelan, on  March 9 2017. To summarize, it informs us that scientists of the Synthetic Yeast Genome Project (Sc2.0) are near to their goal to create a full synthetic yeast genome. In fact, they had already constructed six synthetics yeast chromosomes that represent more than one-third of yeast's entire genome.

Thank you for your feedback!

Hi! Your text is really impressive. You have a current subject, so it's more easy to understand the text. What I liked about your text is that you made a fair portrait of the ALENA and the situation of our country about this subject. Also, your text is really catchy and I learned alot about this subject after my reading.
What I liked about your text is that you use simple words to explain the situation and this made it easy to understand it. But, you should be more attentive to your sentence structure, for example in your text you said that Trump accused Mexico to send rapist and robber, but you didn't supported and prove this fact.

I really liked your text, your french is really good, also the text structure is really good. You started with a catchy introduction. Also, before reading your text I didn't know alot about protectionism, but after my reading I know the positive and the negative effect of this doctrine.
Your french is really good, the sentence structure are awesome and the text is really interesting, but sometimes you repeated the information, for example in the second paragraph you said that protectionism was a good way to stimulate the economy for a short period of time and you repeated it two sentences further.

I like to see your opinion after reading my text. I did not talk about the benefits that exercises have on the kids' brain and I am really glad that you brought this idea. I think it would be nice to study this case and see if it exercise has a bigger influence on the kids. Thank you for reading my text and for making a comment! (Anne-Julie P)

Thanks for the advice! In fact, I watch television in english a lot but I should definitely read more to improve my structure! You're french is good because like you told me but for my english, I can understand what you want to say easily.

Thank you for your comment, I really appreciate it. I agree with you that I need to use more simple terms, but, for my defense, we have a biology class so terms like "eukaryotic" are already in our vocabulary. :-) ( It actually means with a "true" nucleus ) I also agree with the fact that I made a few mistakes, it is my biggest difficulty in the learning of English and I want to become better in the future.
