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.

Campuses of several US Universities have been witnessing massive protests with the students seeking a ceasefire in Israel's war with Hamas. Police have arrested over 550 protesters and some universities are witnessing violent crackdown of protests by the ruthless cops. 

Law enforcement officials at the behest of college administrators have deployed tasers and tear gas against students protesters at Atlanta's Emory University, even though the protests have been largely peaceful, say activists and media personnel present at the spot.

Emil' Keme, professor of English and Indigenous studies, at the University said that the scene reminded him of the civil war in Guatemala as a teenager.

"Police immediately began to force people to move. I felt like I was in a war zone, with all the police and their weapons, the rubber bullets. We were pushed away," Mr Keme told the Guardian describing what happened as soon as cops entered the Emory campus.

“Police took the student next to me, pushed an older lady nearby and then pushed me.”

Student protesters say they are expressing solidarity with Palestinians in Gaza, where the confirmed death toll has topped 34,305, according to the Hamas-run territory's health ministry. They want universities to cut their investments in everything tied to Israel and weapons that fuel the war in Gaza. That means funds run by BlackRock, Google as well as Amazon's cloud service, Lockheed Martin and even Airbnb.

Video circulated widely on social media shows two women who identified themselves as professors being detained, with one of them slammed to the ground by one officer as a second officer then pushes her chest and face onto a concrete sidewalk.

Atlanta police and Georgia troopers are leading a joint operation within the campus to dismantle the tents and camps the activists have set up at the school's quadrangle. Within minutes of the authorities entering the campus, 28 people, 20 of whom were "Emory community members", had been arrested, the institute said in a statement.

The school president said that the videos of police clashing with the students "are shocking" and that he is "horrified horrified that members of our community had to experience and witness such interactions."

The university's response was likely the quickest show of police force in response to a divestment protest among the dozens nationwide that have occurred in recent weeks. It was also probably the only one where pepper balls, stun guns and rubber bullets were used.

Students in Paris blocked access to a campus building at a French university on Friday, as pro-Palestine demonstrations reach Europe.

The students occupied the central campus building of the Paris Institute of Political Studies, known as Sciences Po, and dozens of others blocked its entrance, echoing protest action at American universities.

Students inspired by Gaza solidarity encampments at campuses in the United States blocked access to a campus building at the prestigious French university on Friday.

They blocked the entrance with trash cans, wooden platforms and other items.

The occupation of the Paris university campus came after police broke up a separate protest at the university’s amphitheater outside one of its Paris campuses.

Scores of student protesters gathered at the building’s windows, chanting slogans and holding placards reading “We are all Palestinians,” in defiance of administrators who students say called the police on their peers two days earlier.

Pro-Palestinian student protesters had occupied the amphitheater outside one of the university’s Paris campuses on Wednesday evening.

The US-style student protests, which began over the months-long Israeli regime’s genocidal war against Palestinians in the besieged Gaza Strip, kicked off in the United States and have now spread to European capitals as well as Australia.

In the German capital Berlin, several people were arrested as police violently cleared a camp of Gaza war protesters at the German parliament.

Pro-Palestinian activists are demanding a permanent ceasefire, an end to the Israeli atrocities, and an arms embargo of the Tel Aviv regime.

The Israeli regime launched the war on Gaza on October 7 last year. The genocidal war has killed more than 34,356 Palestinians, most of them women and children.

London: London's Labour mayor Sadiq Khan on Saturday secured a record third term, as the party swept a host of mayoral races and local elections to trounce the ruling Conservatives just months before an expected general election.

Khan, 53, beat Tory challenger Susan Hall by 11 points to scupper largely forlorn Tory hopes that they could prise the UK capital away from Labour for the first time since 2016.

The first Muslim mayor of a Western capital when initially elected then, he had been widely expected to win as the opposition party surges nationally and the Tories struggle to revive their fortunes.

Hours later in the West Midlands, Conservative mayor Andy Street -- bidding for his own third term -- unexpectedly lost to Labour's Richard Parker, dealing a hammer blow to Prime Minister Rishi Sunak.

That narrow loss left the beleaguered leader with only one notable success in Thursday's votes across England, after Tory mayor Ben Houchen won in Tees Valley, northeast England -- albeit with a vastly reduced majority.

In a dismal set of results, Sunak's party finished a humiliating third in local council tallies after losing nearly 500 seats.

"People across the country have had enough of Conservative chaos and decline and voted for change with Labour," its leader Keir Starmer said shortly after confirmation of Parker's victory.

He called the result "phenomenal" and "beyond our expectations".

Writing earlier in Saturday's Daily Telegraph, Sunak had conceded "voters are frustrated" but tried to argue Labour was "not winning in places they admit they need for a majority".

"We Conservatives have everything to fight for," Sunak insisted.

'Spirit and values'

Labour, out of power since 2010 and trounced by Boris Johnson's Conservatives at the last general election in 2019, also emphatically snatched a parliamentary seat from the Tories.

Starmer has seized on winning the Blackpool South constituency and other successes to demand a general election.

Sunak must order a national vote be held by January 28 next year at the latest, and has said he is planning on a poll in the second half of 2024.

Labour has enjoyed double-digit poll leads for all of his 18 months in charge, as previous Tory scandals, a cost-of-living crisis and various other issues dent his party's standing.
On Thursday, it was defending nearly 1,000 council seats, many secured in 2021 when it led nationwide polls before the implosion of Johnson's premiership and his successor Liz Truss's disastrous 49-day tenure.

In the end, they lost close to half and finished third behind the smaller centrist opposition Liberal Democrats.

Meanwhile Labour swept crunch mayoral races across England, from Yorkshire, Manchester and Liverpool in the north to contests across the Midlands.

In London, Khan netted 44 percent of the vote and saw his margin of victory increase compared to the last contest in 2021.

"It's truly an honour to be re-elected for a third term," he told supporters, accusing his Tory opponent of "fearmongering".

"We ran a campaign that was in keeping with the spirit and values of this great city, a city that regards our diversity not as a weakness, but as an almighty strength -- and one that rejects right hard-wing populism," he added.

'Change course'

If replicated in a nationwide contest, the council tallies suggested Labour would win 34 percent of the vote, with the Tories trailing by nine points, according to the BBC.

Sky News' projection for a general election using the results predicted Labour will be the largest party but short of an overall majority.

Speculation has been rife in Westminster that restive Tory lawmakers could use dire local election results to try to replace Sunak.

Despite the returns being at the worst end of estimates, that prospect has not so far materialised.

Ex-interior minister and Sunak critic Suella Braverman warned in the Sunday Telegraph that Sunak's plan "is not working and he needs to change course", urging a more muscular conservatism.

But she cautioned against trying to replace him, warning "changing leader now won't work: the time to do so came and went".

Meanwhile, polling expert John Curtice assessed there were some concerning signs for Labour, which lost control of one local authority and some councillors elsewhere reportedly over its stance on the Israel-Hamas war.

"These were more elections in which the impetus to defeat the Conservatives was greater than the level of enthusiasm for Labour," Curtice noted in the i newspaper.

"Electorally, it is still far from clear that Sir Keir Starmer is the heir to (Tony) Blair."
