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.

New Delhi: IndiGo, India’s largest airline, faced major operational turbulence this week after failing to prepare for new pilot-fatigue regulations issued by the Directorate General of Civil Aviation (DGCA). The stricter rules—designed to improve flight safety—took effect in phases through 2024, with the latest implementation on November 1. IndiGo has acknowledged that inadequate roster planning led to widespread cancellations and delays.

Below are the key DGCA rules that affected IndiGo’s operations:

1. Longer Mandatory Weekly Rest

Weekly rest for pilots has been increased from 36 hours to 48 hours.

The government says the extended break is essential to curb cumulative fatigue. This rule remains in force despite the current crisis.

2. Cap on Night Landings

Pilots can now perform only two night landings per week—a steep reduction from the earlier limit of six.

Night hours, defined as midnight to early morning, are considered the least alert period for pilots.

Given the disruptions, this rule has been temporarily relaxed for IndiGo until February 10.

3. Reduced Maximum Night Flight Duty

Flight duty that stretches into the night is now capped at 10 hours.

This measure has also been kept on hold for IndiGo until February 10 to stabilize operations.

4. Weekly Rest Cannot Be Replaced With Personal Leave

Airlines can no longer count a pilot’s personal leave as part of the mandatory 48-hour rest.

Pilots say this closes a loophole that previously reduced actual rest time.

Currently, all airlines are exempt from this rule to normalise travel.

5. Mandatory Fatigue Monitoring

Airlines must submit quarterly fatigue reports along with corrective actions to DGCA.

This system aims to create a transparent fatigue-tracking framework across the industry.

The DGCA has stressed that these rules were crafted to strengthen flight safety and align India with global fatigue-management standards. The temporary relaxations are expected to remain until February 2025, giving IndiGo time to stabilise its schedules and restore normal air travel.

Mangaluru, Dec 15: Educational institutions in Mangaluru that rely on the popular Mangala Stadium for their annual sports events are bracing for an inconvenience as the city's key sporting venue is set to close its gates for a significant upgrade. The stadium is expected to be unavailable for approximately two months starting from January 15, 2026.

The closure is necessitated by a proposed overhaul of the stadium's facilities, with a special focus on upgrading the synthetic track. Pradeep Dsouza, Assistant Director of the District of Youth Empowerment and Sports (DYES), Dakshina Kannada, confirmed the development.

"Experts have visited the stadium, conducted a thorough inspection, and have given the go-ahead for a complete makeover," Dsouza stated. "Funds have been allocated for the project, and we are currently awaiting the final green signal from state officials to commence the work. We anticipate that the work will likely begin in the second week of January. Consequently, we have stopped renting out the stadium to colleges and other organizations in preparation for the upgrade."

The timing presents a logistical challenge for colleges, as many schools have already concluded their sports meets.

"Colleges will now be organizing their events and will need to find alternative locations to host their sports meets," Dsouza added. He suggested a few potential venues, including the Dakshina Kannada police ground, University College grounds, Panambur grounds, Swaraj Maidan in Moodbidri, and the Mangalore University sports grounds in Konaje.

However, many institutions note that finding a comparable venue will be difficult. While the DK police ground and University College grounds are closer to the city center, they do not possess the extensive facilities and infrastructure offered by Mangala Stadium.

Dr. P Dayananda Pai - P Satisha Govt First Grade College, Carstreet, is one such institution dependent on the stadium. Principal Jayakar Bhandary expressed hope for a swift completion of the work. "We expect the work to be completed at the earliest. If not, we will be forced to look for other venues to host the sports day for our students," Bhandary said, highlighting the pressing need for the city's main sporting facility.
