Glossary:

 "It could be a previous life test, but it could also belong to a meteorite or other sources," said Paul Mahaffy, director of NASA's Solar System Exploration division. 

  Summary:

 NASA has announced that its Curiosity explorer robot, a mission from Mars made in 2012, found organic molecules in rocks of the red planet formed 3 billion years ago, which could indicate that there was life there.  The origin of these molecules can not yet be confirmed. It could be a previous life test, but it could also belong to a meteorite or other sources. Although the reason for the creation of these molecules is still unclear, NASA has pointed out that this type of particle could have been the source of food for a hypothetical microbial life on Mars. In this way, the data collected by Curiosity reveal that billions of years ago, a lake of water within the Gale crater contained all the necessary ingredients for life. 

 Personal opinion: 

 In my opinion this information is very interesting and very visual since it could solve doubts created from our beginning, which is knowing if we are really alone in this world or not in a completely certain way.

What contaminates producing food and 'Let mathematics be with you'

11/06/2018

Glossary:

The impact of food production on the environment is reflected in its carbon footprint. Clara Grima presents a book about mathematics present in everyday activities.

Summary: 

A research carried out by the University of Navarra shows that following a Mediterranean diet is very good for our health, and also for the environment. Consuming Mediterranean foods produces fewer problematic emissions for the ozone layer. The way in which food is produced, processed, distributed and consumed has consequences for ecosystems. Recently the University of Oxford and the Swiss Institute of Agricultural Research have conducted the most comprehensive study to date on the environmental impact of food production. where it shows how apparently identical products, located in the same supermarket location, actually have very different environmental impacts. 

Personal opinion: 

In my opinion it is completely true that the consumption of Mediterranean foods is positive for our health and for the environment, and I think it is a very good thing since I am a person who consumes many foods of the Mediterranean diet.

A 100-meter asteroid will fly over the Earth this Tuesday after eight years disappeared

→ Date: 14 MAY. 2018

→ Scientific field: Astronomy

→ Information source: http://www.elmundo.es/ciencia-y-salud/ciencia/2018/05/14/5af98017e5fdea11148b45c5.html

→ Glossary:

-Asteroid: An asteroid is a rocky, carbonaceous or metallic body smaller than a planet and larger than a meteoroid.

→ Summary: The asteroid '2010 WC9', discovered in 2010 but from which the track was lost until last May 8, will approach the Earth until half the distance from the Moon on Tuesday 15th.

Estimates of its size range between 60 and 130 meters, making the May 15 pass one of the closest ever observed of an asteroid of this size, according to Earth Sky reports.

During the return of 2018, the closest approach to the asteroid '2010 WC9' will occur on May 15 at 22.05 UTC. At that time, the asteroid will be 203,453 kilometers from Earth. According to the calculations of the orbit made by the Jet Propulsion Laboratory of NASA, the approach of May 15 is the closest for this particular asteroid in almost 300 years.

'2010 WC9' is an Apollo-type space rock. At no time will it be visible to the naked eye, since it sweeps the Earth. It could be as bright as a +11 magnitude, which would make it bright enough to be seen in amateur telescopes pointing to the right location and time. Travel through space at a speed of 46,116 kilometers per hour.

Brussels proposes to prohibit the sale of cutlery, plates and plastic straws

Brussels proposes to prohibit the sale of cutlery, plates and plastic straws

→ Date: 29 MAY. 2018

→ Scientific field: Environment

→ Information source: http://www.elmundo.es/ciencia-y-salud/ciencia/2018/05/29/5b0d0f92e5fdea94538b4596.html

→ Glossary:

-Contamination: Pollution is the introduction of substances or other physical elements in a medium that cause it to be unsafe or not suitable for use. The medium can be an ecosystem, a physical medium or a living being. The pollutant can be a chemical, energy.

It is always a negative alteration of the natural state of the environment, and generally, it is generated as a consequence of human activity, considering it a form of environmental impact.

→ Summary: The European Commission has presented a proposal for a directive to reduce the 10 single-use plastic products that are most frequently found on the beaches and seas of Europe. These 10 products represent 70% of all marine waste and the European Commission intends to apply different measures to different articles, so it wants to prohibit the commercialization of single-use plastic products for which there are affordable alternatives, such as sticks of cotton and cutlery, plates, straws, drink shakers and plastic balloon sticks, which must be manufactured with more sustainable materials.

→ Personal opinion: In my opinion this should have been done a long time ago, because there is a lot of plastic pollution in the seas and oceans.

Researches discover how bats carry viruses without getting sick

It is known that bats harbor pathogens such as, the recently very well known in Spain, Ebola and even then they do not show at first glance that they suffer from it.

This is due, according to a recent study, to antiviral pathway called antiviral STING-interferon tat allows them to maintain sufficient defense against the disease without triggering an intensified inmune reaction.

Scientific field: Biology

Glossary:

-Pathogen: that causes or produces disease.

-Via: conduit of the human or animal body through which certain fluids pass.

Test comment:

The system of bats is very interesting because it could be a key to solve many contagious lethal diseases, which would be very favorable.

Discover the farthest oxygenn signal in the universe

A group of researches found a very weak glow of light, thanks to the ALMA telescope, emitted by ionized oxygen.
This oxygen was 10 times farther thanit originated and by calculations it was dicovered that it travelled 13,280 millions light years.
In addition, it was also found with a weaker signal, but as same distance, neutral hydrogen.

Scientific field: Astronomy

Glossary:

-Fusion: Reaction that occurs when two dense cores subjected to high temperatures merge and             form a heavier core; this reactions releases large amount of nuclear energy.

-Wavelenght: Distance between two points corresponding to the same phase in two consecutives waves.

Text comment:

Thanks to this we can know more accurately when was created the first oxygen or at least the one that we believe earlier.

Besides taht if hydrogen has also been found, H2O can be formed and that would behave that can have perfectly life in other distants planets.
