Study shows why it is tough to learn new language for some

New Delhi: A study done at the McGill University in Canada revealed why it is easy for some people to learn a foreign language but not for others. The study suggested that some people’s brains are not able to retain the linguistic skills like others and it happens if there is a lack of communication between the left anterior operculum and the left superior temporal gyrus.

Scientists said that with the study of the difference, it can be predicted who will learn a language quicker and who will not.

A lot of it depends on how much communication happens between the language centers of the brain while a human is resting. This is why the amount of proper sleep is very important.

However, the researchers also said that it is not the only thing that impacts the learning skills of a person. The brain can be manipulated and shaped with the learning and experiences a person has in his life over a time period.

This study proves a socio-political thing that why the native or the local language is so important for a human. Because everyone learns their local language from the time they are in the womb of their mother. It is the first language they learn because it is what they listen first.

Now with cultural impearilism in a country like India, English replaced the mother language and that impacted the life of a common Indian. Not only it was tough to learn English but it brought a feeling of inferiorirty complex into the minds of people which unfortunately still exist.

The worst impacted are the middle-class people of the country. These people have the desire to achieve a higher social status and somehow they think that learning English can be helpful in this bid. Even if they are not comfortable with English, they would not use their mother tongue for example in an MNC restauarant or store.

The importance of local language in the development of a perosn’s life is extremely huge and it cannot be undermined to appease the imperial interests.

Researchers Have Successfully Created Artificial Placenta

Initial tests have already shown that the artificial placenta on the chip does in fact behave in a similar way to a natural placenta: small molecules are allowed to pass through, while large ones are held back, the researchers noted.

Using a high-resolution 3D printing process, Austrian researchers have succeeded in creating an artificial placenta barrier on a chip, a development that can be used to investigate important aspects of nutrient transport from the mother to the foetus.

The placenta ensures the exchange of important substances between the mother and her unborn child, whilst simultaneously blocking other substances from passing through.

“The transport of substances through biological membranes plays an important role in various areas of medicine,” said Aleksandr Ovsianikov, professor at the TU Wien university in Vienna.

“These include the blood-brain barrier, ingestion of food in the stomach and intestine, and also the placenta.”

Studies have shown that diseases such as diabetes and high blood pressure in the mother can affect the transport of substances to the foetus. Until now however, it has been almost impossible to investigate the way in which the many parameters involved interact in such cases.

Using the 3D printing made it possible to produce customised hydrogel membranes directly within microfluidic chips, which are then populated with placenta cells.

This can help provide clarity on how the exchange of glucose between mother and child takes place, the researchers said.

The novel chip consists of two areas — one represents the foetus, the other the mother. Using a specially developed femtosecond laser-based 3D printing process helped produce a partition between them — the artificial placenta membrane.

The high-resolution 3D printing involved a hydrogel with good biocompatibility.

“Based on the model of the natural placenta, we produce a surface with small, curved villi. The placenta cells can then colonise it, creating a barrier very similar to the natural placenta,” Ovsianikov explained.
