Plastic bags can be turned into sensors for safe drinking water

Researchers in Indonesia have developed an innovative method to transform plastic waste into glowing nanomaterials capable of sensing harmful substances in water. At the core of this breakthrough are carbon quantum dots (CQDs), nanoparticles that emit light when exposed to ultraviolet light.

CQDs have the unique ability to act as sensors, detecting pollutants at the molecular level. Traditionally, producing CQDs has required expensive or toxic raw materials. However, the Indonesian research team used waste plastic bags as their starting material, offering a more sustainable and cost-effective approach.

The process involved combining modified pyrolysis with hydrothermal treatment. Using less than 7 percent hydrogen peroxide, they successfully transformed polyethylene from plastic bags into functional CQDs in just 10 hours.

One of the most remarkable features of these plastic-derived CQDs is their ability to detect metal ions, particularly iron ions, in water. This capability presents promising applications for monitoring water quality and detecting harmful contaminants.

EAM S Jaishankar Slams Double Standards At UNGA, Calls For Stronger Global Cooperation Amid Trump’s Russian Oil Threat – VIDEO

United Nations: External Affairs Minister S Jaishankar on Thursday said that terrorism remains a “persistent threat” to development and stressed that the world must show neither tolerance nor accommodation to terrorist activities. Addressing the G20 Foreign Ministers’ meeting here, Jaishankar said those who act against terrorists on any front render a “larger service to the international community as a whole”. Speaking on the correlation between international peace and global development, he said that in recent times, both deteriorated in parallel. “A persistent threat to development is that perennial disruptor of peace – terrorism,” he said, adding, “It is imperative that the world display neither tolerance nor accommodation to terrorist activities.” As the world confronts conflict, economic pressures and terrorism, the limitations of multilateralism and the United Nations are visible, Jaishankar said. “The need for reforming multilateralism has never been greater,” he said, adding that today, the international situation is both politically and economically volatile. “We as members of G20 have a particular responsibility to strengthen its stability and give it a more positive direction that is best done by undertaking dialogue and diplomacy, by firmly combating terrorism, and by appreciating the need for stronger energy and economic security.” Speaking on peace and global development, he said ongoing conflicts, particularly in Ukraine and Gaza, have starkly demonstrated the costs, especially to the Global South, in terms of energy, food and fertiliser security. “Apart from jeopardising supplies and logistics, access and cost themselves became pressure points on nations. Double standards are clearly in evidence,” he said. Jaishankar stressed that while peace enables development, threatening development cannot facilitate peace. He said that making energy and other essentials more uncertain in an economically fragile situation helps no one, and called for moving the needle towards dialogue and diplomacy, “not in the opposite direction towards further complications”. In any conflict situation, there will be a few who have the ability to engage both sides and such countries can be utilised by the international community, both to achieve peace and to maintain it thereafter, he said. “So even as we attempt to address complex threats to peace, the value of encouraging a buy-in from those supportive of such goals should be appreciated,” he said.

City of Fremantle falls aggressively behind on canopy cover target, set for boost in tree planting to keep up

The City of Fremantle has fallen significantly behind its targets to boost canopy cover, and it will now need to plant trees for an additional four years just to meet 80 per cent of its original goal. However, Mayor Hannah Fitzhardinge emphasized that several mitigating factors contributed to the shortfall, including reduced budgets during the COVID years, and stressed that the issue has not been ignored.

Fremantle councillors adopted the Urban Forest Plan in 2017, which outlined the number of trees the council needed to plant over the following decade to achieve its ambitious goal: increasing canopy cover from 13 per cent to 20 per cent. Despite a 2021 decision to revise targets downward by 20 per cent, tree plantings have continued to lag further behind.

In 2023, the council resolved to plant just 600 trees annually in 2024 and 2025 as part of a budget-constrained reset. The city successfully planted 600 trees this year, but this was 838 fewer than the revised target of 1,438, and a substantial 1,198 short of the initial goal of 1,798. The previous year’s planting numbers were also below target, with 533 trees planted—687 fewer than the revised target of 1,220 and 992 fewer than the initial goal of 1,525.

Over the eight years since the program began, the city has planted 5,519 trees. This represents a 33 per cent shortfall compared to its revised target of 8,264 and nearly 50 per cent less than the original goal of 10,330 trees.

Earlier this year, the council requested the chief executive to present a revised target, data on the cumulative shortfall, and a timeline for delivery. All figures are to be published on the city’s website and updated annually. To support this initiative, a budget of almost $700,000 and a full-time staff member have been allocated for 2025-26 to help manage the project.

Last week, the council voted to aim for planting 900 trees annually over the next six years. This plan is set to surpass the revised target of 10,804 trees by 2031, although this will be four years later than initially scheduled.

At the meeting, Councillor Adin Lang acknowledged criticisms from residents and the Fremantle Environmental Network regarding missed targets but described the initial goal as very ambitious.

“I guess you can have a crazy, ambitious goal, but not all of them may be achievable,” he said. “Acknowledging that and extending it by a few years is pretty sensible.”

Mayor Fitzhardinge also highlighted other contributing factors to the shortfall, introducing an amendment noting that it was caused by a lack of initial resourcing, reduced budgets during COVID-affected years, and the unavailability of high-quality planting stock.

“I wanted to just make it clear that we didn’t sort of have an ‘oops’ moment that we had a shortfall of trees,” she said. “There were fairly considered and extensive discussions of trees at every budget that we’ve considered together. It seems a bit rough to read back and just say we had a target and we missed it; there were some factors that contributed to that—it wasn’t just a blind error.”

Councillor Ben Lawver welcomed the renewed investment in tree planting, emphasizing that it forms part of a broader push to increase canopy cover.

“We also have a policy that will be coming back to a future council and other items that could potentially help us grow our urban canopy,” he said. “While it is very important that we plant street trees, and plant trees in our parks and reserves, it is the loss of trees on private property that is really dragging our canopy coverage down.”

Last year, the council found itself at the center of a saga over the protection of a century-old Moreton Bay fig tree on private land. Landowners requested the council to remove the fig from the significant tree list. Protection was stripped from the tree, then reinstated after public backlash, before being removed again.

Councillor Lang concluded by saying it was critical to deliver on targets, allocate budgets, and get trees in the ground. However, the next step would involve refining the work based on the data collected and published.

“We’re using the data and we’re going to get better,” he said. “Hopefully, we can hone in on locations we need to work on and maximize the value of what we’re planting.”

Active Volcano In Andaman & Nicobar Islands Erupts Twice In Eight Days: Why It Matters?

Barren Island Volcano Experiences Two Minor Eruptions Within Eight Days

The Barren Island volcano, located in the Andaman and Nicobar Islands, has witnessed two minor eruptions within just eight days, according to officials cited by news agency PTI. The latest eruption occurred merely two days after a 4.2-magnitude earthquake shook the Andaman Sea on September 18.

Location and Geological Significance

Situated around 140 kilometers northeast of Port Blair, Barren Island is the only active volcano in India as well as in the entire South Asian region. The island sits at the boundary of the Indian and Burmese tectonic plates, making it a highly significant site for geologists studying seismic and volcanic activity.

Recent Eruption Caught on Camera

A dramatic video of one of the recent volcanic eruptions was shared on social media platform X (formerly Twitter) by Sansad TV. Captured by an Indian Navy warship, the clip shows fiery lava gushing out of the crater accompanied by thick clouds of smoke billowing into the sky.

Historical Eruptions of Barren Island

Records suggest that Barren Island’s first eruption dates back to 1787. Since then, the volcano has displayed intermittent activity with notable eruptions in 1991, 2005, 2017, and 2022 before the latest series of minor explosions in September 2025.

A Unique Island With No Inhabitants

Despite being uninhabited, Barren Island draws global curiosity because it is the only active volcanic island in South Asia. The landscape is starkly different from the rest of the Andaman Islands. While most beaches in the region boast white sands, Barren Island’s shores are blanketed in volcanic ash.

The island does not support human settlement, and entry onto it is strictly prohibited due to safety concerns. However, tourists can explore its surroundings via boat or ship excursions. The nearby waters are crystal clear and teeming with rich marine life, making it a popular spot for scuba diving and snorkeling enthusiasts.

Although inhospitable for humans, the island does support some forms of wildlife. According to the Andaman Islands’ official tourism website, species such as feral goats, bats, rodents, and a few varieties of birds have adapted to the harsh volcanic environment.

Why Barren Island Matters

Barren Island is not only a natural wonder but also a crucial geological landmark. Its eruptions provide insights into the dynamic tectonic processes of the Indian Ocean region. Scientists frequently monitor the island to better understand volcanic patterns, seismic activity, and potential risks to nearby regions.

Why takeoffs at airports are about to become noisier

**Why Takeoffs at Airports Are About to Become Noisier**
*By Dwaipayan Roy | Sep 24, 2025 | 8:00 PM*

A recent study from the University of Reading has revealed that climate change could lead to increased noise pollution from departing airplanes around European airports. The research focuses on how rising air temperatures affect aircraft take-off patterns, finding that on average, departing aircraft climb angles will decrease by 1-3%, with some particularly hot days potentially reducing these angles by as much as 7.5%.

**Potential Impact on Noise Levels**

The study examined noise levels at 30 European airports, with a special focus on Airbus A320 aircraft—commonly used for short European flights—and how changes in climb angles affect noise pollution as the climate changes. Dr. Jonny Williams, lead author of the study, warned that climate change could expose thousands more people in London to noise pollution from departing aircraft over the next three decades.

Currently, approximately 60,000 people live within the 50dB noise footprint of a typical A320 aircraft in central London. However, due to climate change and increasing population density, an additional 2,500 people could be brought within this noise boundary in the near future.

**The Role of Sound Frequencies**

Dr. Williams explained that the problem is intensified by different types of sound frequencies. Low-frequency noise, which travels further distances, is expected to increase the most. These deeper sounds are particularly concerning as they can contribute to stress and disrupt sleep, raising public health concerns.

**Looking Ahead: Challenges Beyond Technology**

Despite advancements in engine technology aimed at reducing noise, Dr. Williams cautioned that rising temperatures caused by unchecked greenhouse gas emissions will make managing airport noise more difficult. Without decisive action on climate change, these environmental factors could outweigh technological improvements, exacerbating noise pollution issues around airports.

This study highlights the complex challenges climate change poses not only to the environment but also to urban living conditions, emphasizing the need for integrated approaches to mitigate its diverse impacts on society.

Ben Affleck and Jennifer Garner’s daughter Violet powerfully advocates for mask mandates and children with long COVID at United Nations event

Violet Affleck, the daughter of Hollywood A-listers Jennifer Garner and Ben Affleck, appeared before the United Nations in New York City on Tuesday. The 19-year-old activist spoke about the importance of masks and other preventative measures more than five years after the COVID-19 pandemic changed life across the globe.

Violet participated in an event titled **Healthy Indoor Air: A Global Call to Action**. As a first-year student at Yale’s Davenport College, she emphasized the ongoing need to wear masks to curb the spread of COVID-19.

“It is neglect of the highest order to look children in the eyes and say, ‘We knew how to protect you, and we didn’t do it,'” the Ivy League student said during her speech.

She highlighted an alarming lack of responsibility in the current generation, noting how adults are eager to return to business as usual despite the ongoing risks. “For adults, the relentless beat of ‘back to normal,’ ignoring, downplaying, and concealing both the prevalence of airborne transmission and the threat of Long COVID manifested in a series of choices,” Violet explained.

“Our present is being stolen right in front of our eyes,” Violet added, stressing that young people have “lacked both real choice in the matter and information about what was being chosen for us.”

In closing, she called on the audience to recognize clean, filtered air as a fundamental human right, comparable to filtered water. “We can create clean air infrastructure that is so ubiquitous and so obviously necessary, tomorrow’s children don’t even know why we need it,” she said.

Earlier this May, Violet authored an article published in the *Yale Global Health Review* focused on Los Angeles’s organized response to COVID-19. In the article, she stressed that fully eliminating the virus involves not only wearing masks but also employers providing paid sick leave and universal healthcare. Additionally, she advocated for environmental measures aimed at keeping the air clean.

Violet also urged communities to stay organized and ensure that masks are distributed free of charge to those in need, reinforcing the importance of collective action in ongoing pandemic response efforts.

Air pollution linked to dementia, Alzheimer’s disease progression: Study

**Air Pollution Linked to Dementia and Alzheimer’s Disease Progression: Study**

*By Snehil Singh | Sep 23, 2025, 06:21 PM*

A recent study conducted by the University of Pennsylvania has uncovered a significant link between long-term exposure to fine particulate matter (PM2.5) and the progression of dementia and Alzheimer’s disease. Published in *JAMA Neurology*, the research analyzed over 600 brain autopsy cases spanning from 1999 to 2022. The findings revealed that individuals exposed to higher levels of PM2.5 exhibited more advanced Alzheimer-related neuropathological changes (ADNC).

### Key Research Findings

The study highlighted that air pollution may be more harmful to brain health than tobacco. It showed that nearly two-thirds of the connection between pollution and dementia is attributable to Alzheimer’s-related brain changes. Moreover, participants with recorded clinical dementia experienced more severe cognitive and functional decline when exposed to prolonged air pollution.

### Expert Insights from India

Medical professionals in India are witnessing firsthand the devastating effects of air pollution on brain health. Dr. Manjari Tripathi from AIIMS emphasized that air pollution might pose a greater risk to neurological health than tobacco, linking it to disorders such as stroke and dementia.

Dr. Daljit Singh, vice-chairman and head of neurosurgery at Max Smart Super Speciality Hospital, described dementia as an emerging public health challenge in India. While the exact causes of Alzheimer’s remain under study, he noted that pollution is increasingly recognized as a high-risk factor.

### Health Recommendations

To mitigate the risk of developing dementia and Alzheimer’s disease related to air pollution, experts recommend practical measures such as:

– Wearing N95-grade masks when outdoors
– Using air purifiers indoors
– Reducing exposure to dusty and polluted environments

### The Bigger Picture: Air Pollution and Public Health

Air pollution, particularly fine particulate matter like PM2.5, represents a major global health hazard. It contributes not only to cardiovascular and respiratory conditions but also to neurological diseases. Delhi, in particular, faces alarming air quality issues during winter months, frequently experiencing “poor” to “severe” pollution levels.

This hazardous air environment poses a significant threat not only to respiratory health but also to brain health, especially among older adults.

Protecting yourself from air pollution is becoming increasingly important, as emerging research continues to reveal its profound impact on cognitive health and the progression of neurodegenerative diseases.
