THE MATERNAL LOVE

Summary:

Bringing a child into the world is considered one of the most beautiful things there, especially for the mother what has raised the fetus and has been it for nine months in her tummy, creating an incredible link between them. Recent studies have shown that maternal love changes the brain. Behind that love scientists believe that there are a hormone called occitocina. At first this hormone had got the charge of the regulation of salt and water and over time has come to function as a neurotransmissor and as a hormone together. It is produced in the hypothalamus and is responsible for maintaining close relationships with our offsprings. One of the strongest relationships that exist for a longtime is the one between a mother and his child bond. After all, is more important the interaction with the baby  , although it is true, a caress or a simple contact with the mother make occitocina release and, therefore, continues to create that bond between making stronger.

Crittical appraissal:

It's hard to believe that a simple hormone is able of regulating or feeding a feeling, which is something abstract. However, it makes sense to be a hormone made in the brain and interacts both during pregnancy . Clearly, the fact of having a life for nine months inside you creates links between both of them who will be almost impossible to break but what really amazes is the cause. Therefore, we can conclude that as the baby receives more love he will have more cognitive abilities. But an example that not all feelings will issue related to this hormone or made ​​to share the same genes are cases of adoption . Mother and son create strong bonds regardless of genes.

Glossary:

Oxytocin: is a mammalian neurohypophysial hormone.

Gene: A gene is the molecular unit of heredity of a living organism.

Offspring: children or young of a particular parent or progenitor.

News' title: Ditching farm pollution – literally

Reducing fertilizer runoff benefits both farmers and the environment

 

Date of publication: April 17, 2015

 

Source of information: Science news for students:

https://student.societyforscience.org/article/ditching-farm-pollution-%E2%80%94-literally

 

Scientific field: Environmental biology

 

Extract:

Fertilizers and pesticides from farms become pollutants once they leave the farm. These chemicals are carried away by ditches, and most of them end up in lakes or rivers.

 

This causes some negative effects. This runoff can poison animals in rivers where ditches empty and it can harm the environment. Besides, washed away fertilizer helps algae and bacteria grow faster.

A demonstration project, Shatto Ditch Project, is trying to improve the situation by giving other alternatives to runoff ditches. Farmers consider that they have decreased their costs in ditch maintenance and fertilizers.

 

Critical appraisal: Dear environment:

Sometimes we do not think about the consequences of what we do. We simply carry on doing the same actions as if it was a routine, like that's what we are supposed to do. I've chosen this article because it's a clear example that we can change things and make our world a little better.

 

 

By reading this article, I have realised that little ideas can end up being great changes if we do dare to try. Shatto Ditch Project, created by Jennifer Tank, has demonstrated that there are always other alternatives if we firmly look for them. Tank, seeing the problematic caused by the runoff of ditches, devised a two tier ditch for funneling water near farms. This new method entailed lots of advantages: there were less costs for farmers to assume, and it was environmentally friendly. Besides, the soil had more nutrients as they were retained in the soil.

In conclusion, I believe that this society should have more consciousness and more committed to our world. If we had real concern, we'd be always thinking about what's the best and most ecological way of doing things, and this planet of ours may be better.

Glossary:

algae Single-celled organisms. As aquatic organisms, they grow in water. Like green plants, they depend on sunlight to make their food.

bloom (in microbiology) The rapid and largely uncontrolled growth of a species.

floodplain The nearly flat land that runs along the side of a river, for some distance out from the water. When the river floods, it spills over into this plain, which is built up, over time, with the silt left as the waters recede.

limnology A branch of ecology that studies inland waters, including lakes, streams and groundwater.

microcystins A class of toxins produced by some freshwater algae that are also known as cyanobacteria. Most of these toxins work by poisoning the liver.

no till The somewhat recent practice by some farmers to leave crop residues (stalks, leaves and roots) in place over the winter, instead of turning over the dirt and burying these materials as soil nutrients.

peer review (in science) A process in which scientists in a field carefully read and critique the work of their peers before it is published in a scientific journal.

phosphorus A highly reactive, nonmetallic element occurring naturally in phosphates. Its scientific symbol is P.

runoff The water that runs off of land into rivers, lakes and the seas. As that water travels over land, it picks up bits of soil and chemicals that it will later deposit as pollutants in the water.

Silt Very fine mineral particles or grains present in soil. They can be made of sand or other materials.

tillage (v. to till) A common practice by farmers of turning over soil on croplands to remove weeds and/or cultivate the land.

toxin A poison produced by living organisms, such as germs, bees, spiders, poison ivy and snakes.
