Mysterious Fog in the US , Canada and UK: A dense, eerie fog with a "burning chemical-like smell" has spooked a good part of North America and parts of the United Kingdom and Canada. With social media amplifying all concerns, this phenomenon has sparked attention across all social media platforms. However, at the heart of this mysterious fog are a conjunction of natural events, social psychology, and environmental conditions that culminated in all the conspiracy theories and public health fears. Here's a closer look at the mysterious fog, its potential causes, and the societal response it has triggered.
The first reports of this "mysterious fog" came in from Florida where a resident said that they experienced respiratory symptoms, feverish warmth, and stomach cramps after contact with the fog. Similar stories started flooding social media, and within a day or two, a sinister force seemed to sweep across the United States, Canada, and parts of the UK. From Texas to Minnesota, people reported weird odors and health issues that they thought were linked to this bizarre atmospheric event.
Some witnesses were said to see "white particles" swirling through the air; theories ranged from a chemical attack or experimental weapon to drone-related chemical dispersals and references to historical military experiments, such as the infamous 1950s "Operation Sea-Spray."
Fuel to the fire were added when videos and posts, hundreds of thousands in number, began circulating on social media sites like TikTok and X (formerly Twitter) speculating on the origin of the fog. Hashtags like #ToxicFog went trending for days. Hysteria created a self-reinforcing loop in which every post spurred further scrutiny and fear.
Fog is essentially a low-lying cloud formed when the air temperature cools to its dew point, causing water vapor to condense into tiny droplets or ice crystals. Several types of fog—advection fog, radiation fog, and valley fog—can form depending on conditions such as warm, moist air moving over cooler land or when temperatures plummet rapidly under clear skies.
Such chemical-like smell as reported during the occurrence of fog events is sometimes attributed to air pollution. It acts like a sponge, where it absorbs these pollutants, which include sulfur dioxide and nitrogen oxides, among others, that emit from industries. This mixture, therefore, leads to a stench that could be mistaken as unnatural or even toxic.

High moisture levels from fog can significantly exacerbate symptoms related to respiration, but especially in already predisposed asthmatics and allergy patients. The connection of these symptoms with actual fever, stomach cramps, and puffy eyes is too remote. Experts assume that the irritating effects of entrapped pollutants trapped in fog tend to affect more the eyes and throat rather than the rest of the body affected by some report.
Social media amplified a natural weather event into a health epidemic. It made the personal experience of individuals become a cause for fear and speculation, a domino effect.
According to psychologists, this is a concept of selective perception, wherein once people's attention is drawn to environmental anomalies, they begin to notice them. This mirrors earlier panics, such as the Seattle windshield pitting panic of 1954. Then, atomic bomb testing caused fear in many and started to have people looking at their windshields for small marks that they had not seen before. Likewise, postings on the strangeness of the fog probably increased public awareness and suspicion, with people looking to attach unrelated symptoms to the phenomenon.
The fog hysteria shares a commonality with other instances of mass panic, such as the "drone sightings" of recent years or the Cold War-era fears of biological warfare.

These events underscore how fear can cloud judgment, especially when amplified by social media and sensationalist headlines. While historical cases, such as "Operation Sea-Spray," offer concrete evidence of the existence of unethical experiments, the jump from a natural weather condition to theories of chemical attacks exemplifies a more modern trend of connecting unrelated dots, all wonderfully seeded in distrust and anxiety.
Despite the swirling rumors, meteorologists and scientists are in agreement that the mysterious fog is not as alarming as it seems. It is well known that fog traps and amplifies pollutants, especially in urban and industrial regions. Moreover, winter months are the most conducive for fog formation, so its recent prevalence is unsurprising.
On the other hand, environmentalists advise that the fog should wake everyone up to increased levels of pollution. The reported odors and health irritations could be just symptoms of far deeper systemic issues like industrial emissions and lack of control over air quality.
The authorities must be transparent in their communication to combat misinformation and allay public fears. Governments and environmental agencies must provide timely updates on weather phenomena, air quality, and health risks. Initiatives like real-time pollutant tracking and public education campaigns can help demystify natural occurrences while addressing valid environmental concerns.
The mysterious Canada fog is a compelling case study in how environmental events intersect with psychology and societal dynamics. While rooted in natural phenomena, the fog became a vessel for collective fears, amplified by modern technology and historical anxieties.
In this information era where communication occurs at an almost lightning pace, the fog becomes a metaphor that reminds everyone about scientific literacy, environmental responsibility, and an effective balance when considering public concern. Whether perceived as a marvel of nature or as a tale that serves to teach, it left a very powerful mark in people's minds.

In yet another milestone in India’s digital healthcare, the government has launched the Swasth Bharat Portal, which aims to bring together the fragmented health systems in the country.
The portal, unveiled during the recent 10th National Summit on Innovation and Inclusivity by Union Minister for Health and Family Welfare JP Nadda, signifies a decisive shift towards a more integrated, efficient, and scalable digital public health architecture.
The portal aims to enable seamless integration with the Ayushman Bharat Digital Mission (ABDM) and support the exchange of patient records through the ABHA health account system.
The Swasth Bharat Portal has been conceptualized as an aggregator platform that integrates existing program systems through an API-based federated architecture.
It enables interoperability and convergence, creating a unified digital layer across programs.
It is a one-stop integrated platform that brings multiple national health programs onto a single interface.
It eliminates the need for multiple logins and repetitive data entry, and significantly reduces the administrative burden on healthcare providers while enhancing efficiency at all levels.
The portal also provides a single platform for easy access, along with data visualisation tools and the use of data at the local level for monitoring and evidence-based planning.
It is ABDM-compliant and supports integration with ABHA (Ayushman Bharat Health Account), enabling seamless and secure exchange of patient health records.
It is designed to evolve into a comprehensive and interoperable digital health ecosystem, further integrating with national registries such as the Healthcare Professionals Registry (HPR) and Health Facility Registry (HFR).
The new portal will help:

The Swasth Bharat portal will also lead to substantial government savings both in terms of human resources, time, and IT infrastructure as compared to the current individual portals being managed by different program divisions, the Health Ministry said.
Further, the portal enables a shift towards an integrated, efficient, and scalable digital public infrastructure with significant efficiency gains.
The Swasth Bharat Portal thus represents a transformative step towards convergence, efficiency, and data-driven governance in India’s public health system.
Researchers have just found that eggs should be eaten every day for lowering Alzheimer's disease risk. (Photo credit: AI generated)
Eggs are literally one of the healthiest foods on the planet. They offer proteins, healthy fats, vitamin D, choline, and other essential vitamins and minerals. Therefore, it is a no-brainer that eating eggs is associated with several health benefits—from weight management to a healthier heart to even diabetes management. And now, according to researchers at the Loma Linda University School of Public Health, eating eggs is associated with a lower risk of Alzheimer's disease as well. Alzheimer's is often diagnosed in people aged 65 years and above. Researchers have found that eating one egg a day for at least five days can reduce Alzheimer's risk by 27 per cent.
Experts at the Loma Linda University School of Public Health found that, as compared to people who never eat eggs, eating at least five servings of the high-protein food option can significantly reduce Alzheimer's risk. Furthermore, the study also noted that less frequent consumption of eggs can work wonders in helping to dodge memory loss and other cognitive health-related symptoms. Researchers in the study found that eating eggs one to three times a month can reduce the risk by 17 per cent, and eating two to four times a week reduced the risk by 20 per cent. The study was published in the Journal of Nutrition.
Eggs are a whole food, and that is because of the nutrients they offer and their subsequent benefits for overall health. They are also sources of essential nutrients that improve brain health—they offer choline, phosphatidylcholine, and acetylcholine—all of which are critical for synaptic function and memory. They are also sources of zeaxanthin and lutein, carotenoids that accumulate in brain tissues and are linked to lower oxidative stress and better cognitive performance. Eggs are sources of omega-3 fatty acids and phospholipids that constitute 30 per cent of the total egg lipids essential for neurotransmitter receptor function.
Researchers in the study said that their aim was to understand the relationship between modifiable dietary factors linked to Alzheimer's disease risk. Experts stated that they studied egg consumption in visible ways, for instance, eating them fried, scrambled, or boiled, or in hidden ways such as packaged or baked goods. Scientists emphasised that moderate intake of eggs is an important part of a balanced diet. Whether for breakfast, as a post-workout meal, or simply as a snack satisfying cravings, this versatile food option must find its way into your diet. And after years of research and studies (with more to come), it can be said that eggs are key to a healthy life now and even years later.

Officials at the US Food and Drug Administration have blocked publication of several studies supporting the safety of widely used vaccines against COVID-19 and shingles in recent months, according to a spokesman for the Department of Health and Human Services (HHS).
While the studies found serious side effects to be very rare, the HHS said they were pulled over concerns about their conclusions. These withdrawals aim to limit access to vaccines, reflecting broader policy changes under US Health Secretary Robert F. Kennedy Jr., a staunch critic of vaccines.
"The studies were withdrawn because the authors drew broad conclusions that were not supported by the underlying data. The FDA acted to protect the integrity of its scientific process and ensure that any work associated with the agency meets its high standards," said Andrew Nixon, a spokesman for the HHS, which oversees the FDA, in an email to Reuters.
The last one year of Trump administration, along with Kennedy as the head of the HHS, saw significant cut in research funding for vaccine development. It also fueled doubt on vaccines, and blocked other information supporting their safety.
The list includes research on COVID vaccine effectiveness by scientists from the Centers for Disease Control and Prevention (CDC).
In October, the scientists were directed to withdraw two COVID vaccine studies that had been accepted for publication in medical journals. Further, in February, top FDA officials did not sign off on submitting abstracts about studies of Shingrix, a shingles vaccine, to a major drug safety conference.
“The design of that study fell outside the agency’s purview,” Nixon said on rejecting the shingles vaccine. He did not address a question about the Shingrix safety study, which found the vaccine to be safe.

In June 2025, his office asked CDC staff members to delete from the agency’s website a 17-page summary supporting the safety of thimerosal, an additive largely removed from vaccines 25 years ago.
Further, in August, Kennedy called the journal Annals of Internal Medicine to “immediately retract” a large Danish study concluding that the vaccine additive aluminum salts were safe. However, the study was not retracted.
Recently, Dr. Jay Bhattacharya, who was serving as interim leader of the CDC, canceled the publication of a report concluding that the Covid vaccine sharply cut the odds of hospitalizations and emergency room visits last winter, saying the study had limitations.
“At a moment when public trust in institutions like the CDC is fragile, we cannot afford to lower our standards,” Dr. Bhattacharya wrote in an editorial about news coverage of his decision.

Last June, a CDC panel backed by Kennedy voted to remove the mercury-based preservative thimerosal from flu shots, despite long-standing clinical evidence of its safety.
In August 2025, the HHS said it would wind down nearly $500 million in mRNA vaccine development, canceling 22 federal projects overseen by the Biomedical Advanced Research and Development Authority (BARDA), a government-backed funding body.
Other vaccines, including flu and hepatitis A, were also removed from routine recommendations. He also directed the CDC to stop recommending the vaccine for healthy pregnant women and children.
