6th text commentary. Google makes it again!!!

Google sells security sistem devices without mentioning the incorporation of microphones on it's products.

Summary: We have confirmed the autenticity of the famous sentence"google hears more that he should do" with the discover of microphones on Nest Secure, a product that acts as a security sistem. 

Although some people think that the microphones may be there to hear sounds so he can know when is people in or out, the majority of the people think that is there to spy the customers, and it doesn't seem that much strange coming from google. There has been more tries from google of trying to sneek into people's houses. Google has said that the microphone is there for a future coming google assistant, but that doesn't make any sense being a security sistem. It would be like asking for the weather to your bacuum.

One thing is certain and is that there's something strange happening with google because of his desperate tries of spying. But we can be completely sure about that, not yet.

6th TEXT COMMENTARY: Oldest rock from Earth... In the Moon?! - Esther Salvador

HEADER 
Oldest Rock From Earth Found On The Moon

SUMMARY
A lunar sample collected by the Apollo 14 astronauts almost 50 years ago has more terrestrial than lunar characteristics. The reason for it is that some billion years ago a large impact dislodged it from Earth and went to the Moon. Four billion years later we find this rock formed by quartz, zircon and feldspar, regular materials on Earth, in the Moon, crystallized in an Earth-like oxidized environment and at terrestrial temperatures.
Then, they also discovered the rock crystallized 20 kilometers beneath the Earth's surface, which implied a different distance between Earth and the Moon. They were more than a half the distance closer than they are nowadays.
The international team of scientist belive this kind of show us the period of intense bombardment in our Solar System’s history.
For this sample to be in the Moon's surface for us to collect it, it is thought that about 26 million years ago an asteroid hit the Moon, forming a big crater which we can still see, bringing this rock to the surface.

TEXT COMMENTARY

This text show us our capacity of learning from the discovery of some rock sample and take conclusions from its conditions. Thanks to a 2 gram rock, we can know and confirm what happened 4 billion years ago, or at least have an idea of it. This makes you think how eventhough we haven't lived long in this universe, we can still learn from it and know what happened if we have samples. This conclusion lead us to another conclusion, which is: the Univers is simple to observe. It may not be really accurated, but the fact that the universe is made by materials well known on Earth, makes you think we can really learn more about this mysterious universe we live in.
A rock doesn't tell you much about anything. But it's compostition does, its condition does, also the size, trajectory... They are all variables we can study.
It is true we are very small in the universe, and the human being has been around for a really short amount of time, but if we can tell what happened 4 year billion years ago and visualize it by examining a 2 gram rock, I think we can learn a lot of things from the Universe if we can observe it and take samples.
It's a shame we need oxygen to live. If we didn't, we could go much farther and discover so much more. If we didn't destroy everything we touch, that would be, for sure, a great thing.

Notícia 06: Una nova una espècie de vespa converteix aranyes en els seus esclaus zombis - Victor Garcia

- Heading:

This creepy new wasp species turns social spiders into zombie slaves

- Summary:

  In the rainforest of Ecuador, some kind of zombie apocalypse is taking place. Spiders of the same specie (Anelosimus eximius), are behaving in an unusual way. Although these spiders don’t leave their colony as they live in groups, they are leaving them on their own and isolating themselves in a silk cocoon.

   These quirky behavior is because a new type of parasitoid wasps (belonging to the Zatypota genus). These wasps need to parasite another being in order to complete their life cycle.  The parasite process begins with the adult wasps laying an egg in the spider’s abdomen. Then, it hatches, and starts to feed on the spider’s blood to fatten itself and eventually it takes over the spider’s body. Before the spider dies, it isolates itself in a silk cocoon.

   After 11 days isolated in the cocoon, a fully formed wasp emerges from it, ready to restart its life-cycle.

- Text commentary:

   I chose to comment this new because it makes me feel interested and intrigued about how unknown remains the wild life to us. The abilities of the animals we don’t even know they have are fascinating, just as fascinating as how the parasite being function. As they need another being as they actually cannot live by themselves, not until the fully develop their bodies.

   In my opinion, as there are a lot more parasite type of beings, the study focused on this specie of wasps because they do really control its host body. They control its physical and mental being as they are able to confront the host’s will.

6th text commentary: CONSUMING A LITTLE MARIJUANA ALREADY MODIFIES THE BRAIN OF A TEENAGER

Header

Consuming a little marijuana already modifies the brain of a teenager

Summary

The news exposes how the consumption of 1 or 2 marijuana cigarettes can affect the brain of an adolescent even if he never smokes again. This conclusion is contained in a study conducted by Hugh Garavan at the University of Vermont, in which he compared the brains of several 14-year-old boys who admitted to using cannabis. In addition, additional factors related to their physical characteristics and others such as sex or if they also consumed alcohol, tobacco or other substances were taken into account.

The subject of this news did not contain a very specific vocabulary that I did not understand.

Text commentary 

I have chosen this news because the use of marijuana in adolescents is very common nowadays. It is an activity that almost nobody is fully aware of the risk of consuming, even if it is a single marijuana cigarette in life. Indeed, as the news says, the brain is affected with the consumption of only 1 or 2 marijuana cigars. With this dose the effect on the brain is immediate and is reflected in the surface of gray color that increases rapidly affecting its development and can trigger future diseases as serious as schizophrenia.

The study was conducted in Ireland, but of course the results can be extended to the entire juvenile population of the world where marijuana use is unfortunately common. The problem consists in the erroneous perception that it is a substance that has no harmful effects. The study has shown, however, that this is not the case.

The solution to the problem of marijuana use is complex because young people do not know its harmful effects. That is why it is essential to act in two ways. First, informing young people and the general population of this kind of studies that report the danger of this substance. Second, it is necessary that the police act with more rigor against the consumption of marijuana, strictly sanctioning their consumption. In addition, it is important that the police act to prevent plantings and drug trafficking from other countries.
