Melbourne, Oct 12: The virus that causes Covid-19 can survive on banknotes, glass and stainless steel for up to 28 days, much longer than the flu virus, Australian researchers said on Monday, highlighting the need for cleaning and handwashing to combat the virus.

Researchers at Australia's national science agency, CSIRO, found that at 20 degrees Celsius (68 degrees Fahrenheit) the SARS-COV-2 virus remained infectious for 28 days on smooth surfaces such as plastic banknotes and glass found on mobile phone screens. The study was published in Virology Journal.

By comparison, Influenza A virus has been found to survive on surfaces for 17 days.

CSIRO's research involved drying virus in an artificial mucus on a range of surfaces at concentrations similar to samples from Covid-19 patients and then extracting the virus after a month.

Experiments done in controlled laboratory environments at 20, 30 and 40 degrees C showed that the survival time declined as the temperature increased.

"Establishing how long the virus really remains viable on surfaces enables us to more accurately predict and mitigate its spread and do a better job of protecting our people," CSIRO Chief Executive Larry Marshall said in a statement.

Proteins and fats in body fluids can also sharply increase virus survival times.

"The research may also help to explain the apparent persistence and spread of SARS-CoV-2 in cool environments with high lipid or protein contamination, such as meat processing facilities, and how we might better address that risk," said Trevor Drew, director of the CSIRO’s Australian Centre for Disease Preparedness.

Australia has fared much better than most other rich nations in combating Covid-19, with a total of about 27,000 infections and 898 deaths in a population of 25 million.

The epicentre of the country's second wave of infection, Victoria state, reported 15 new cases on Monday, well shy of a target of less than five which the government has set for the easing of a hard lockdown in the state capital Melbourne.

New South Wales, the most populous state, reported six new cases on Monday, five of whom were returned travelers in quarantine.

An Indian Air Force (IAF) Tejas fighter jet crashed on Friday, November 21, afternoon during its aerial demonstration at the Dubai Air Show, plunging to the ground at around 2:10 pm local time while performing a manoeuvre before thousands of spectators.

The IAF confirmed the incident, stating that a Tejas aircraft participating in the show had crashed and that further details were being gathered. An Air Force spokesperson said more information would be shared after initial assessments.

The crash sent thick black smoke billowing into the sky near the airport, causing panic among visitors, including families and children who had gathered to watch the display. Authorities have not yet confirmed whether the pilot managed to eject before the aircraft went down. Emergency response teams rushed to the scene, and officials have not released information on casualties or damage so far.

The Tejas is a 4.5-generation, multi-role fighter aircraft developed indigenously by Hindustan Aeronautics Limited (HAL). Designed for versatility, it is capable of offensive air support, close combat, ground attack missions and maritime operations. The aircraft family includes single-seat fighters and twin-seat trainers for both the Air Force and Navy.

HAL describes the latest version, the LCA Mk1A, as the most advanced in the series, featuring an AESA radar, an upgraded electronic warfare suite with radar-warning and self-protection jamming, smart multifunction displays, a digital map generator, a combined interrogator–transponder system and a modern radio altimeter. These enhancements significantly improve the aircraft’s combat capability and survivability.

Further updates from IAF and UAE authorities are awaited.

Mangaluru, Dec 2: Mangaluru International Airport responded to a medical emergency late on Monday night. Air India Express flight IX 522, travelling from Riyadh to Thiruvananthapuram, was diverted to Mangaluru Airport after a passenger in his late 30s experienced a medical emergency on board.

The Airport’s Operations Control Centre received an alert regarding the passenger’s health condition. The airport activated its emergency response protocol, mobilising the airport medical team and coordinating with stakeholders including CISF, immigration, and customs. 

Upon landing, airport medical personnel attended to the passenger, assessed his condition, and arranged to shift him to a local tertiary-care hospital for further treatment. The passenger’s relatives accompanied the passenger, who incidentally received necessary medical care on board, which helped stabilise the situation.

Following the handling of the emergency, the flight departed for Thiruvananthapuram at 2:05 am on Tuesday.

"We appreciate the cooperation of all parties involved, and this incident reaffirms our ongoing commitment to prioritising passenger safety and readiness to respond to unforeseen emergencies with professionalism and care," the Airport spokesperson said.

Bengaluru, Nov 26: Karnataka is taking its first concrete steps towards lifting a three-decade-old ban on student elections in colleges and universities. Deputy Chief Minister D.K. Shivakumar announced Wednesday that the state government will form a small committee to study the reintroduction of campus polls, a practice halted in 1989 following incidents of violence.

Speaking at a 'Constitution Day' event organised by the Karnataka Congress, Mr. Shivakumar underscored the move's aim: nurturing new political leadership from the grassroots.

"Recently, (Leader of the Opposition in Lok Sabha) Rahul Gandhi wrote a letter to me and Chief Minister (Siddaramaiah) asking us to think about restarting student elections," Shivakumar stated. "I'm announcing today that we'll form a small committee and seek a report on this."

Student elections were banned in Karnataka in 1989, largely due to concerns over violence and the infiltration of political party affiliates into campus life. The ban effectively extinguished vibrant student bodies and the pipeline of young leaders they often produced.

Mr. Shivakumar, who also serves as the Karnataka Congress president, said that former student leaders will be consulted to "study the pros and cons" of the re-introduction.

Acknowledging the history of the ban, he added, "There were many criminal activities taking place back then. We’ll see how we can conduct (student) elections by regulating such criminal activities."

The Deputy CM reminisced about his own journey, which began on campus. He recalled his political activism at Sri Jagadguru Renukacharya College leading to his first Assembly ticket in 1985 at the age of 23. "That's how student leadership was at the time. Such leadership has gone today. College elections have stopped," he lamented, adding that for many, college elections were "like a big movement" where leaders were forged.

The move, driven by the Congress high command's push to cultivate young talent, will face scrutiny from academics and university authorities who have, in the past, expressed concern that the return of polls could disrupt the peaceful academic environment and turn campuses into political battlegrounds.
