Google Doodle honors Har Govind Khorana – biochemist who deciphered DNA

In 1968, Khorana was awarded the Nobel Prize in Physiology or Medicine along with fellow scientists Robert W Holley and Marshall W Nirenberg.

Google on Tuesday honored Indian-American scientist Har Gobind Khorana with an illustration on google doodle on the 96th birth anniversary of the noble laureate well known for his work on DNA and the construction of the first synthetic gene.

Born in a village in Raipur of British India in 1922, Khorana was the youngest of five children of a village clerk. He went to the United Kingdom to pursue PhD after the completion of his bachelors and masters degree from Lahore. During his tenure, working under Professor Vladimir Prelog in Zurich for one year, Khorana became an expert on chemical synthesis of nucleic acids and proteins.

Having graduated from the University of Punjab in India in 1945, Khorana later undertook courses at the University of Liverpool and University of Cambridge. The Indo-American scientist began work on his Nobel winning contribution to the field of medicine after he moved to Canada in 1952 and started working at the University of Columbia. Later the Nobel laureate moved to United States and continued his research work at the University of Wisconsin.

At the University of Wisconsin, Khorana worked on his research work with fellow scientists Marshall W Nirenberg and Robert W Holley from 1952 to 1960 was granted American citizenship in 1966. Khorana made his second scientific breakthrough with the construction of the first synthetic gene in 1972 – soon after his fellow scientist Nirenberg discovered the first phase of the genetic code.

In 1968, Khorana was awarded the Nobel Prize in Physiology or Medicine along with Robert W Holley and Marshall W Nirenberg for “their interpretation of the genetic code and its function in protein synthesis”. He was also awarded the National Medal of Science for his iconic work in the field of genetics.

According to the biography of Khorana, he was married to Swiss national Esther Elizabeth Sibler – on whom the biography showered praises for bringing a “consistent sense of purpose … at a time when he felt out of place everywhere and at home nowhere”.

The legendary biochemist passed away on November 9, 2011.

He said metro services were operational across just 245 km in five cities when Prime Minister Narendra Modi assumed office in 2014. The network has since expanded to 1,170 km across 26 cities.

The minister said India could overtake the US in terms of metro rail network length in the next two years and become the world’s second-largest country in this segment after China.

China currently has around 8,000 km of metro rail lines, according to the figures cited by the minister.

Indore metro extension inaugurated

The minister made the remarks after inaugurating an extended section of the Indore metro. The project was built at a cost of around Rs 2,850 crore.

The Indore metro was earlier operating commercially on a six-km stretch between Gandhi Nagar and Super Corridor-3 stations. Following the extension, the service will operate on a 17-km route between Gandhi Nagar and Malviya Nagar Chauraha.

Madhya Pradesh Chief Minister Mohan Yadav said the metro service would mark a new phase in Indore’s development. He also said the network would eventually be extended to Ujjain and other nearby areas.

PM Modi returns to SRCC after 13 years, revisits 2013 glass full speech

PM Narendra Modi returned to SRCC after 13 years for its centenary celebrations, revisiting themes from his landmark 2013 address.

PM Narendra Modi

Prime Minister Narendra Modi returned to Delhi University’s Shri Ram College of Commerce (SRCC) on Saturday, 13 years after his previous visit to the institution as Gujarat chief minister. 

His latest visit came as SRCC marked its centenary celebrations. Modi’s 2013 address at the college had attracted significant attention as he spoke about India’s youth, governance and the country’s demographic potential.

In 2013, Modi was Gujarat chief minister and had not yet been named the BJP’s prime ministerial candidate. He returned to the same campus this year as Prime Minister, having completed 12 years as Prime Minister and serving his third consecutive term. 

What PM Modi said at SRCC in 2013

The 2013 lecture was titled Emerging Business Models in the Global Scenario. The address also covered governance and India’s young population.

He described India’s youth as a source of national strength rather than simply a group of new-age voters. He also highlighted India’s demographic advantage and argued that the country needed to make better use of its young population.

One of the notable moments from the speech involved a glass of water.  Modi contrasted the conventional descriptions of a glass as half full or half empty and said he viewed it as full, with half containing water and the other half air.

The speech also included his remarks on technology and young Indians. Referring to an anecdote from a visit to Taiwan, Modi used the phrase “mouse-charmers” to describe Indians using computers and suggested that young Indians had the ability to influence the world through technology.

‘Minimum government, maximum governance’

Modi’s 2013 address also touched on governance. He spoke about the role of government and the need for better governance.

He also spoke about India’s potential in the 21st century. 

Modi returns as PM for SRCC centenary

The September 5 visit coincided with Teachers’ Day and SRCC’s 100th anniversary. The Prime Minister’s Office had announced that Modi would participate in the college’s centenary celebrations and address the gathering. SRCC was established in 1926 by industrialist and philanthropist Sir Shri Ram.

Earlier this year, Modi also met the SRCC governing body at his residence in April in connection with the college’s centenary celebrations and released a commemorative postage stamp marking the occasion. 

The return to SRCC came 13 years after his 2013 appearance at the college, when he addressed students as Gujarat chief minister.

Supreme Court judge calls police assault on CJP protesters very distressing

Supreme Court judge Justice Ujjal Bhuyan criticised alleged police assaults on CJP protesters and raised concerns over excessive force.

Supreme Court

Supreme Court judge Justice Ujjal Bhuyan has criticised the assault of protesters by police personnel during the recent CJP demonstrations in Delhi, describing the conduct as “very, very distressing” and a matter of serious concern.

Speaking at the launch of retired IPS officer Yashovardhan Azad’s book Policing the Republic, Justice Bhuyan said the detachment expected from police officers appeared to be diminishing.

He expressed concern over young Indian Police Service officers personally participating in the assault of protesters and demonstrators.

Justice Bhuyan stresses need for responsible policing

Justice Bhuyan said effective policing does not require excessive use of force or infringement of human rights. He emphasised that the police play an important role in maintaining public confidence because citizens generally approach the police when they feel they have been wronged.

He said maintaining the credibility of the police force was therefore of “utmost importance”.

The judge’s remarks come amid continuing scrutiny of the police and paramilitary response to the CJP protests in Delhi.

Supreme Court panel to examine police action

The Supreme Court has constituted a high-level panel to investigate allegations concerning the use of force by Delhi Police during the July 20 student protests at Jantar Mantar and the subsequent Parliament march.

The panel, headed by former Supreme Court judge Justice R Subhash Reddy, will examine complaints relating to lathi charges, tear gas, pellet guns and electronic batons. It will also look into allegations of targeted harassment or molestation of female protesters and review available CCTV and video footage.

The police response during the protests has faced criticism, while Delhi Police has maintained that its personnel were also attacked during the clashes.

Judge raises concern over custodial deaths and torture

Justice Bhuyan also spoke about custodial torture and deaths, describing custodial death as one of the gravest crimes in a society governed by the rule of law.

He stressed that torture and cruel, inhuman or degrading treatment cannot be accepted, regardless of whether such conduct takes place during investigation, interrogation or other circumstances.

The judge further warned that when government functionaries themselves become lawbreakers, it can undermine respect for the law and encourage lawlessness.

He questioned whether citizens lose their fundamental rights simply because they have been arrested by police.

‘Fake encounters’ cannot be part of policing

Justice Bhuyan also addressed allegations of extra-judicial killings, commonly referred to as “fake encounters”. Referring to a 2011 Supreme Court judgment, he said such encounters undermine the rule of law.

He stressed that an “encounter philosophy” cannot become part of legitimate policing and said proven fake encounters involving serving police officers must be treated with the utmost seriousness.

The Supreme Court’s panel will now examine the allegations surrounding the police action during the July 20 protests as scrutiny of the events continues.
