Artificial intelligence in education world

11 Mar 16
A recent article on Forbes talks about how artificial intelligence (AI) can play a significant role in the education industry. The world, as is, today is running on AI! From social media sites suggesting friends to cameras with sensors clicking the perfect picture to Siri managing our calendar- AI has sneaked into our lives through various entries. So, what is AI? It can be defined as the theory and development of computer systems that are able to perform tasks which normally require human intelligence. Visual perception, speech recognition, decision-making, and translation between languages, are some of its features. However, one area where it is still prominently lagging behind is our education system. AI can help in evaluating the curricular materials and become a tool in adaptive learning. It can automate activities like grading in school. While AI may never be able to match human grading, it is getting quite close. Teachers, around the world, can now automate grading for various multiple-choice questions. How much is happening in India is yet to be recognised. Other benefit that can be drawn from it is through individualised learning with adaptive learning programmes, games and software. These systems can put more emphasis on topics where a child is facing problems in learning and can repeat things that students need to master. Thus helping each child to learn at his/her own pace! It can also help in improving the quality of education. For example, it can alert teachers about their lectures which are not being imbibed by the students or where they are confused. Coursera, a massive open online course provider, is using this by alerting a professor if a large number of students are giving wrong answers for an assignment. The teacher, can then, send customised messages to future students to avoid the same mistakes. While these are some of the ways AI has touched the education industry, there’s still a long way for it to become a universal language of education.

CANCER RISK FOR MARS ASTRONAUTS DOUBLES

26 Jun 17

Cosmic rays, like titanium and iron and atoms, because of their very high rates of ionization, devastate the nucleus and cause mutations in the cells they traverse, and thus cause cancer.

Earlier studies predicted that astronauts are at the risk of circulatory diseases central nervous system effects, cancer, cataracts, and acute radiation syndromes due to galactic cosmic rays exposure.

A new predictive model to access cancer risk for a human mission to Mars was carried out by the University of Nevada, Las Vegas. Its results published in Scientific Reports reveal that cosmic rays radiation spreads from the damaged cells to nearby healthy cells, which doubles cancer risk to the Mars astronauts. This is because they will be outside the magnetic field protection of the earth.

"Exploring Mars will require missions of 900 days or longer and includes more than one year in deep space where exposures to all energies of galactic cosmic ray heavy ions are unavoidable. Current levels of radiation shielding would, at best, modestly decrease the exposure risks" said Francis Cucinotta, the research lead.

More studies focusing on cosmic ray exposure induced cancer risks should therefore commence before long term space missions.

Raja Ram Mohan Roy: The Real Hero of 18th Century

25 Jun 17

The Pioneer of modern Indian Renaissance, Raja Ram Mohan Roy, is a real hero. Today, we know him for his great efforts for the society. He brought remarkable reforms in the 18th and 19th century India. The list of his efforts includes the abolition of Sati Pratha which was among one of the most inhuman and brutal acts.

Besides, his efforts were also instrumental in eradicating the purdah system and child marriage. In 1828, Ram Mohan Roy formed the Brahmo Samaj, uniting the Bhramos in Calcutta, a group of people, who had no faith in idol-worship and were against the caste restrictions.

Roy also got an opportunity to visit England as an ambassador of the Mughal King to ensure that Bentick's regulation banning the practice of Sati was not overturned. Moreover, Raja Ram Mohan Roy had a great contribution to create the freedom of speech in the country.

He was a staunch supporter of free speech and expression. He also fought for the rights of the vernacular press. He also brought out a newspaper in Persian called 'Miratul- Akhbar' (the Mirror of News) and a Bengali weekly called 'Sambad Kaumudi' (the Moon of Intelligence).

Stress Grants Lifelong Vulnerability, Said Scientists

23 Jun 17

According to a new study, early stress confers lifelong vulnerability causing alterations in a specific brain region. The study was conducted at the Icahn School of Medicine at Mount Sinai. The study shown early life stress increases lifelong susceptibility to stress through long-lasting transcriptional programming in the brain reward region implicated in mood and depression.

The study was focused on ‘epigenetics’- the study of changes in the action of genes cause which is different from the changes in DNA code that we inherit from our parents. The researchers also added that instead by molecules, ‘epigenetics’ also regulate when, where, and to what degree our genetic material is activated.

This kind of regulation-procured from the function of transcription factors-- specialized proteins that bind to specific DNA sequences in our genes. Additionally, such regulation drives either encourage or shut down the expression of a given gene, stated the researchers. The previous researches, conducted on humans and animals, have shown that early life stress increases the risk for depression and other psychiatric syndromes. However, the neurobiology linking the two has remained indefinable so far.

May 2017 Analyzed as Second Warmest May

22 Jun 17

In 137 years of modern record-keeping, May 2017 was found to be the second warmest May. The records were analyzed by scientists at NASA's Goddard Institute for Space Studies (GISS) in New York. The scientists found this by a monthly analysis of global temperatures at Institute.

The scientists found that the last month was 0.88 degrees Celsius warmer. It was warmer than the mean May temperature from 1951-1980. The top irregularities in temperatures of May have happened in the last two years only. 2016 was the hottest year on record. It was at 0.93 degrees Celsius warmer than the May mean temperature. The temperature of May 2017 was 0.05 degrees cooler than the temperature of May 2016.

The temperature of May 2017 was very closely warm to the third warmest May on records.  May 2017 was just 0.01 degrees Celsius warmer than the third warmest May that happened in the year 2014.
