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.

Fog that Feeds Fear

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.

Scientific Explanation of the Dense Mysterious Fog

1. What is Fog?

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.

2. Why the Chemical Smell?

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.

3. What are the Health Concerns?

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.

Psychological Effects of Mass Panic Caused by Social Media

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.

Environmental and public health scientists have begun warning against the dangers of having free living amoeba in water systems that are capable of triggering severe diseases in humans.

In a recent perspective article published in Biocontaminant, the researchers noted that climate change, deteriorating water infrastructure and limited systems for monitoring and detection are the key factors that have allowed these pathogens to spread and persist.

Corresponding author Longfei Shu of Sun Yat sen University explained: "What makes these organisms particularly dangerous is their ability to survive conditions that kill many other microbes.

"They can tolerate high temperatures, strong disinfectants like chlorine and even live inside water distribution systems that people assume are safe."

The scientists also emphasized that not only can amoebae spread illnesses on its own, it can also act as hidden carriers for other harmful microbes.

By sheltering bacteria and viruses inside their cells, amoeba these unicelled organisms protect these pathogens from disinfection and help them persist and spread in drinking water systems. This so-called Trojan horse effect may also contribute to the spread of antibiotic resistance among humans.

How Dangerous Is Amoeba?

Amoeba are single-celled organisms that naturally live in soil and water. Most species do not cause harm yet some can prove to be fatal.

Some of the diseases caused by this kind of bacteria include Amebiasis (Amoebic Dysentery), an intestinal infection by Entamoeba histolytica, causing diarrhea, cramps and potential liver abscesses as well as Primary Amoebic Meningoencephalitis (PAM) from Naegleria fowleri, a rare but nearly always fatal brain infection from contaminated water entering the nose.

Effects of amoeba-caused infections range from intestinal issues (liver abscesses, anemia, peritonitis) to severe neurological damage (coma, seizures, death) from brain-eating types, with Acanthamoeba causing eye infections (keratitis).

Experts recommend thoroughly washing your hands after toilet use and before handling food, drinking clean water especially in unsanitary conditions and avoiding getting water up your nose in warm freshwater to prevent such infections.

The Indore Crisis

This comes days after the recent Indore sewage water controversy which has claimed the lives 10 people and left over 1,400 people hospitalized, according to Indore Mayor Pushyamitra Bhargava.

However, locals claim that the outbreak has instead caused the death of 17 residents, including a six-month-child. The situation has also left Parvati Bai, 67, with kidney failure, a brain stroke and symptoms of Guillain-Barré Syndrome, or GBS.

GBS is a rare condition where your immune system attacks the nervous system and can cause paralysis as well as death, in certain cases.

The outbreak occurred due to lapses in civic infrastructure. Investigation revealed that a toilet constructed directly above a main drinking pipeline near a police outpost, without a mandatory safety tank resulted in the sewage mixing with drinking water.

The US Food and Drug Administration has approved the use of a blood test which can help diagnose Alzheimer’s disease in adults aged 55 and above.

The blood test, known as Lumipulse, can detect amyloid plaques associated with Alzheimer’s disease and has proven to be a “less invasive option” that “reduces reliance on PET scans and increases diagnosis accessibility.”

FDA Commissioner Martin A. Makary said of the landmark decision, "Alzheimer’s disease impacts too many people, more than breast cancer and prostate cancer combined.

"Knowing that 10% of people aged 65 and older have Alzheimer's, and that by 2050 that number is expected to double, I am hopeful that new medical products such as this one will help patients."

It remains unclear when this test will be available for commercial use across the world.

What Is Alzheimer’s Disease?

About 8.8 million Indians aged 60 and above are estimated to being living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.

Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure to this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.

How Does The Test Work?

As explained by Dr Abhay Moghekar, an associate professor of neurology at Johns Hopkins University School of Medicine, who helped study and evaluate the test for FDA approval, "If this test is positive, there’s a greater than 90% chance that you have amyloid plaque in your brain.

"Getting a blood test is gonna be far easier, quicker and cheaper,” he said. “It’s going to allow early access to therapy, so it is going to revolutionize care of patients with dementia."

However, the federal agency also noted certain limitations associated with the test such as it can only be used for patients 55 and older who are already experiencing memory problems.

The FDA also cautions that the test is not intended as a standalone diagnostic tool for Alzheimer’s and results should be interpreted based on the patient’s medical history and other assessments, such as cognitive testing.

People who stop using weight-loss medications can regain weight and return their original size within two years, a new BMJ study says.

Researchers have found that those who lose weight using blockbuster GLP-1 drugs such as Ozempic could regain about 0.4kg every month after quitting these treatments. In contrast, those who lost weight through exercise, diet and other factors only gained 0.1kg.

Investigator Dr Susan Jebb, from Oxford University told the BBC, "People buying these need to be aware of the risk of fast weight regain when the treatment ends."

Ozempic (semaglutide) is a prescription injectable GLP-1 medication primarily approved for adults with Type 2 diabetes to manage blood sugar levels. However, the drug has gained immense popularity among those trying to lose weight as it can reduce hunger and help people feel full for longer, which forces the body to burn fat deposits to stay functional.

In clinical trials, people with obesity using semaglutide have shown to lose an average of about 15% of their body weight over 68 weeks. Most people begin to see noticeable results within 8 to 12 weeks of taking the drug.

The official price in India for a once-weekly Ozempic injection pen ranges from approximately ₹8,800 for the 0.25 mg dose to around ₹11,175 for the 1 mg dose per month. Insurance coverage is generally inconsistent for weight loss indications.

What Did The Study Find?

The researchers analyzed 37 studies that included 9,341 participants out of which nearly half had taken had taken GLP-1 medications. This included 1,776 people who received the newer, more effective drugs semaglutide, sold as Ozempic and ‌Wegovy by Novo Nordisk , and tirzepatide, sold ‌as Mounjaro and Zepbound by Eli Lilly.

Apart from discovering that patients could regain all their weight in 1.7 years, the scientists also found that those who lost weight using semaglutide ‍and tirzepatide, cwould gain 0.8 kg per month.

Dimitrios Koutoukidis, Oxford University researcher and senior study author, “But because people on semaglutide or tirzepatide lose more weight ‍in the first place, they all end up returning to baseline at approximately the same time".

Heart health risk factors, such as blood pressure and cholesterol levels, that benefited ⁠from the drugs were projected to return to pre-treatment levels within 1.4 years after stopping the medications.

Why Does The Weight Come Back?

Dr Adam Collins, an expert in nutrition at the University of Surrey, told the BBC that when the body stops receiving a regular dose of appetite suppressants such as GLP-1 drugs, hunger returns and can lead to overeating.

He told the publication, "Artificially providing GLP-1 levels several times higher than normal over a long period may cause you to produce less of your own natural GLP-1, and may also make you less sensitive to its effects.

"That's not a problem when taking the drugs, but as soon as you withdraw this GLP-1 'fix', appetite is no longer kept in check and overeating is far more likely.

"This is further exacerbated if the individual in question has relied solely on GLP-1 to do the heavy lifting... artificially suppressing their appetite without them establishing any dietary or behavioural changes that would help them in the long run."
