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.

RBI cuts repo rate to 5.25%, paving the way for cheaper loans

The RBI has cut the repo rate to 5.25%, aiming to support growth as inflation softens. The central bank also raised GDP projections and announced liquidity-boosting measures.

Reserve Bank of India

The Reserve Bank of India (RBI) reduced the key repo rate by 25 basis points to 5.25% on Thursday, signalling relief for borrowers as banks are expected to offer lower EMIs on home and vehicle loans. Governor Sanjay Malhotra announced the move after the conclusion of the three-day Monetary Policy Committee (MPC) meeting.

RBI prioritises growth as inflation eases

Malhotra said the decision was unanimous, with the central bank choosing to focus on supporting economic momentum despite concerns over a weak rupee. The repo rate was earlier cut in June from 6% to 5.5% amid easing inflation trends.

The RBI now projects Consumer Price Index (CPI) inflation at 2% for FY2025-26, significantly softer than earlier estimates. For the first quarter of FY2026-27, inflation is expected at 3.9%, lower than the previous projection. The governor noted that rising precious metal prices may contribute to the headline CPI, but overall risks to inflation remain balanced.

GDP outlook strengthened

In a strong upward revision, the central bank increased the GDP forecast for the current financial year to 7.3%, previously estimated at 6.8%. Growth for the October–December quarter has also been revised to 6.7%.

The last quarter registered a six-quarter high expansion of 8.2%, reflecting resilient demand and steady credit flow.

“The growth-inflation balance continues to offer policy space,” Malhotra said, reiterating that the RBI’s stance remains neutral.

Other key decisions

Alongside the repo rate cut, the RBI announced adjustments to key policy corridors:

  • Standing Deposit Facility (SDF): 5%
  • Marginal Standing Facility (MSF): 5.5%

To improve liquidity and strengthen monetary transmission, the RBI will conduct forex swaps and purchase ₹1 lakh crore worth of government bonds through Open Market Operations (OMO).

RBI reviews a challenging year

Reflecting on 2025, Malhotra said the year delivered strong growth and moderate inflation even as global trade and geopolitical uncertainties persisted. He added that bank credit and retail lending remained healthy, providing support to the economy.

IndiGo flight chaos deepens as over 500 services cancelled, passengers stranded for hours

Over 500 IndiGo flights were cancelled nationwide, leaving passengers stranded without food, clarity or their luggage as airports struggled to manage the disruption.

IndiGo flight

India’s largest airline continued to face massive operational breakdowns, triggering frustration among travellers at major airports across the country. From piles of unattended suitcases to passengers waiting over 12 hours without food or clarity, the disruption stretched into its fourth consecutive day.

Long delays, no communication leave passengers anguished

Several travellers at Delhi airport described the situation as “mental torture”, as thousands of unclaimed suitcases lay scattered across the terminal. Many slept on the floor, while others expressed anger over the lack of communication from airline staff.

One flier said he had been waiting for over 12 hours without any explanation: “Every time they say one-hour or two-hour delays. We were going to a wedding but don’t even have our luggage.”

A passenger in Hyderabad recounted a similar ordeal, saying the flight was delayed indefinitely with no food, water, or updates from the airline. At the airport, some travellers blocked an Air India flight in protest over the lack of arrangements.

Goa and Chennai airports also witnessed tense moments. Videos from Goa showed fliers shouting at IndiGo staff as police attempted to calm the situation. At Chennai, CISF denied entry to IndiGo passengers due to heavy congestion.

Major metro airports impacted; cascading cancellations nationwide

Flight cancellations and delays were reported across multiple airports:

  • Over 200 flights were cancelled in Delhi
  • More than 100 each in Mumbai and Bengaluru
  • Around 90 in Hyderabad
  • Dozens more in Pune, Vishakhapatnam, Chennai and Bhopal

Pune airport stated that parking bay congestion worsened the situation, as several IndiGo aircraft remained grounded due to lack of crew. Other airlines continued operations without disruption.

Airport authorities said they had mobilised additional manpower for crowd control and passenger support.

IndiGo admits planning lapses, says more cancellations expected

The airline acknowledged a “misjudgment” in assessing crew requirements under revised night-duty norms, which it said created planning gaps. Winter weather and airport congestion further aggravated the crisis.

IndiGo informed the aviation ministry and DGCA that some regulatory changes—such as the shift in night-duty timings and a cap on night landings—have been rolled back temporarily to stabilise operations.

The airline warned that cancellations may continue for another two to three days, and from December 8, schedules will be trimmed to prevent further disruption.

In a message to employees, CEO Pieter Elbers said restoring punctuality would not be an “easy target”.

Airline issues apology amid nationwide frustration

In a late-night statement, IndiGo apologised to customers and industry partners, acknowledging the widespread inconvenience caused by the disruptions. The airline said all teams were working with authorities to bring operations back to normal.

Delhi-NCR air quality

The Delhi government has announced a large-scale deployment of mist sprayer technology to tackle rising air pollution, with Chief Minister Rekha Gupta confirming that 305 mist sprayers will be installed across nine pollution hotspots in the capital.

Mist sprayers to curb dust at critical locations

During an inspection at ITO, Gupta said the mist sprayers already operational at the site are performing effectively. She noted that 35 poles at ITO have been fitted with these machines, which are helping suppress dust—a major contributor to air pollution in Delhi.

According to the Chief Minister, trials conducted in certain NDMC areas have shown promising results, reinforcing confidence in the technology.

High-level committee to guide pollution-control measures

Gupta announced the formation of a high-level expert committee that will advise the government on effective measures to reduce pollution. The panel will include senior officials from various departments as well as environmental specialists, including experts from IITs. Officials stated that the committee will receive special powers to implement pollution-mitigation strategies.

Departments directed to repair roads, add greenery

The Chief Minister said departments including PWD, DSIIDC and DDA have been instructed to fix potholes, repair and carpet roads, plant foliage along dividers and islands, and take other measures to reduce pollution sources.

She urged residents to report potholes on the government portal for quicker action.

Appeal to RWAs to prevent biomass burning

To curb winter pollution, Gupta advised Resident Welfare Associations (RWAs) to distribute electric heaters to security guards to discourage biomass burning, which significantly contributes to seasonal pollution spikes.
