Jerusalem, Aug 25: Wastewater containing coronaviruses, such as the one behind the Covid-19 pandemic, may be a potential threat, according to a new review of studies that calls for additional filtration steps in sewage treatment plants to successfully remove viruses.

The research, published in the journal Nature Sustainability, by an international collaboration of 35 researchers, assessed recent studies on coronaviruses in wastewater.

According to the review research, conventional wastewater treatment provides only partial removal of coronaviruses, with safe disposal or reuse depending on the effectiveness of final disinfection.

"There is ample reason to be concerned about how long coronaviruses survive in wastewater and how it impacts natural water sources," said study lead author Edo Bar-Zeev from the Ben-Gurion University of the Negev (BGU) in Israel.

"Can wastewater contain enough coronaviruses to infect people? The simple truth is that we do not know enough and that needs to be rectified as soon as possible," Bar-Zeev said.

According to the scientists, sewage leaking into natural watercourses might lead to infection with the novel coronavirus SARS-CoV-2 via airborne spray.

They said treated wastewater used to fill recreational water facilities, like lakes and rivers, could also become sources of contagion, adding that fruits and vegetables irrigated with this water may also be an indirect infection route.

The scientists recommended immediate, new research to determine the level of potential infection, if any, and how long coronaviruses last in various bodies of water and spray.

"Wastewater treatment plants need to upgrade their treatment protocols and in the near future also advance toward tertiary treatment through micro- and ultra-filtration membranes, which successfully remove viruses," the scientists noted.

They added that wastewater can also be used to monitor or track Covid-19 outbreaks.

Using a new methodology, the researchers recently detected and traced the presence of the novel coronavirus, and calculated its concentration to pinpoint emerging Covid-19 hotspots.

Mangaluru: A seemingly harmless YouTube advertisement has cost a Mangaluru man his life savings, after he fell victim to an elaborate investment scam and lost a staggering ₹55 lakh.

According to the police complaint, the victim was lured in by a man named Shardul Jani, who claimed that a trading app called Abans Pro would deliver high returns. On February 11, the man made an initial investment of ₹15,000. A trading account was created for him, which soon began displaying encouraging profits.

Buoyed by these promising numbers and under constant persuasion from the accused, the man was convinced to invest more. Reassured that the money could be withdrawn at any time, he not only continued investing himself but also involved his relatives, who collectively transferred ₹39 lakh into his account for further investments.

Between February 11 and March 27, the victim transferred a total of ₹55 lakh to multiple bank accounts provided by the accused. But when he finally attempted to withdraw the funds, nothing came back. The profits were a mirage—his money had vanished.

Realising he had been conned, the man approached the Bajpe police, who have registered a case and begun an investigation into the fraudulent scheme.

Bengaluru, Apr 11: In a significant development, the Karnataka Cabinet on Friday formally accepted the controversial Socio-Economic and Educational Survey, popularly known as the caste census, nearly a decade after it was conducted. The report will be taken up for detailed discussion in a special Cabinet meeting on April 17.

The survey was originally carried out in 2015 by the Karnataka State Commission for Backward Classes under the chairmanship of H. Kantharaj, and finalised in February 2024 by his successor, K. Jayaprakash Hegde. The long-awaited report—comprising 50 volumes of detailed caste- and community-related data—was placed before the Cabinet in a sealed cover, which was opened during Friday’s meeting.

Backward Classes Welfare Minister Shivaraj Tangadagi, while briefing the media, said the report would now be distributed to all Cabinet ministers so they could examine its findings ahead of the April 17 meeting. Though the government did not disclose the contents of the report, it sought to validate the survey’s legitimacy by presenting statistical data.

“As per the 2011 Census, Karnataka’s population was 6.11 crore. By 2015, when the survey was conducted, it had grown to an estimated 6.35 crore. The survey covered 5.98 crore people—a coverage of 94.17 percent,” Tangadagi said.
He added that only 37 lakh people, or 5.83 percent, were left out of the enumeration process.

Highlighting the scale of the operation, the minister said 1.6 lakh government officials participated in the survey. An expert committee was constituted, which developed 54 criteria to guide the data collection. The state government also engaged Bharat Electronics Limited (BEL) to manage the survey data under a ₹43 crore agreement, with the total expenditure reaching ₹165 crore.

Law and Parliamentary Affairs Minister H. K. Patil announced that a special Cabinet session will be held on April 17 to deliberate on the report's contents. When asked about concerns over the completeness of the data, Patil responded, “Even in the national Census, some people are left out. A 94 percent coverage is a very significant achievement.”

The caste census remains a politically sensitive issue in Karnataka. Dominant communities such as the Lingayats and Vokkaligas have questioned the methodology of the 2015 survey, alleging undercounting. In contrast, Other Backward Classes (OBCs) and SC/ST groups have welcomed the report, arguing that it sheds light on social realities long ignored.

The Congress party had pledged to act on the caste census in its manifestos for the 2023 Karnataka Assembly elections and the 2024 Lok Sabha polls. National party leader Rahul Gandhi has also been advocating for a nationwide caste census.

The Cabinet’s acceptance of the report comes just days after Chief Minister Siddaramaiah’s meeting with Rahul Gandhi in New Delhi, and the Congress Working Committee’s session in Ahmedabad.

Six Ministers Skip Cabinet Meeting

At least six ministers were notably absent from Friday’s Cabinet meeting. These included:

    S. S. Mallikarjun and Laxmi Hebbalkar (both Lingayats)

    M. C. Sudhakar and K. Venkatesh (both Vokkaligas)

    R. B. Timmapur (SC)

    Madhu Bangarappa (Idiga community)

However, Minister Patil clarified that despite their absence, all ministers have endorsed the Cabinet’s collective decision, regardless of caste or community affiliations.

Washington: In a move that stunned markets and political observers alike, US President Donald Trump on Wednesday announced a 90-day pause on his sweeping tariff regime—granting relief to all countries except China. Just a day earlier, such a reversal had seemed unimaginable.

Trump said the pause was prompted by the cooperative stance of over 75 nations, which had refrained from retaliating against his earlier tariffs. These countries, he claimed, chose negotiation over confrontation. During the pause, a reduced reciprocal tariff of 10% will be in place.

However, Trump made it clear that China would face no such leniency. Citing Beijing's alleged trade abuses and “lack of respect” for global markets, he announced an immediate hike in tariffs on Chinese imports to 125%, up from the earlier 104%.

“At some point, hopefully in the near future, China will realize that the days of ripping off the US and other countries is no longer sustainable or acceptable,” Trump wrote on Truth Social.

Despite repeatedly resisting pressure from within his own party and business circles to halt the tariff spree, Trump’s sudden pivot was reportedly triggered by alarm bells inside the US Treasury Department. According to CNN, Treasury Secretary Scott Bessent raised red flags about a dramatic selloff in the bond market, which, if left unchecked, could spiral into a financial crisis.

Speaking to the media after the announcement, Trump seemed to suggest that the decision came from instinct rather than strategy.

“We didn’t have access to lawyers… We wrote it up from our hearts. You have to be flexible,” he said.

The markets responded instantly. The Dow Jones Industrial Average surged over 2,500 points, while the Nasdaq jumped 12.2%, its best day in 24 years. The S&P 500 rose 6%, oil prices climbed more than 4%, and the dollar strengthened.

Impact on India

India, which had been hit with a 26% customized reciprocal tariff, saw its markets rattled in recent weeks. The pause offers a much-needed breather, as New Delhi works to finalize a multi-sectoral trade deal with Washington.

Ministry of External Affairs Spokesperson Randhir Jaiswal confirmed that talks are underway. “We hope to address these issues and conclude this agreement expeditiously,” he said, underlining the strong economic ties between the two nations.
