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.

Nipah virus outbreak in India has triggered screenings across Asian airports. However, the health authorities of the Kolkata hospital where two nurses were admitted confirmed that one of the two nurses has been discharged from hospital. While this may be a good sign, there is still need to be cautious of the virus.

Nipah Virus Outbreak In India: How Does It Work?

Experts and doctors are still telling people to be cautious of what they eat, as the fatality rates are from 40 per cent to as high as 75 per cent. It is a zoonotic infections that infects vital organs like brain and lungs. However, the virus is also able to manipulate body's immune system.

Nipah Virus In India: How Does It Affect Immune System?

Nipah virus is lethal because it can outpace, suppress and misdirect immune responses. Speaking to NDTV, Dr Dip Narayan Mukherjee, Consultant, Microbiology and Infectious Diseases at CK Birla Hospitals said, Nipah virus leaves the body unable to clear the infection in time. "Understanding this immune disruption is critical to explaining why Nipah causes severe encephalitis, multi-organ failure and high mortality, and why early detection and containment remain the most effective tools against it."

This immune disruption begins early in the infection. The body’s first line of defense against viruses is the innate immune system, which relies heavily on interferons. These signalling proteins alert neighboring cells to the threat and trigger antiviral mechanisms that slow viral replication.

“One of the earliest ways Nipah evades immunity is by interfering with the innate immune response,” Dr Mukherjee says. “The virus suppresses interferon activity, allowing it to multiply rapidly before the immune system can respond adequately.”

Research published by the World Health Organization and other virology institutes shows that specific Nipah virus proteins block interferon signalling pathways. This gives the virus a crucial head start, enabling widespread infection before the immune system is fully activated.

Nipah Virus Outbreak In India: Inflammation And Low Immunity

As the infection progresses, Nipah targets the cells lining blood vessels, a feature that sets it apart from many other respiratory viruses. Damage to these vessels allows the virus to spread to multiple organs, including the brain, while also triggering widespread inflammation.

Instead of a controlled antiviral response, the body releases large amounts of inflammatory molecules. This excessive inflammation leads to tissue injury, swelling and organ dysfunction, contributing to respiratory failure, neurological symptoms and circulatory collapse in severe cases.

Another hallmark of Nipah infection is immune exhaustion. Although the virus does not directly infect most immune cells, the intense inflammatory environment causes them to become overactivated and eventually dysfunctional. Once these defense cells lose their ability to control viral replication, the infection accelerates, and supportive care becomes less effective in later stages.

When Nipah crosses into the brain, immune control becomes even more limited. The brain’s immune responses are naturally restrained to prevent damage, allowing the virus to persist. At the same time, inflammation causes swelling, seizures and encephalitis. Neurological complications remain the leading cause of death in Nipah outbreaks.

Nipah Virus Outbreak In India: Why Antibodies Against The Infection Arrive Late

The adaptive immune response, which includes antibody production and virus-specific T-cells, also struggles to keep pace with the rapid spread of Nipah. By the time neutralizing antibodies are produced, significant organ damage may have already occurred, particularly in the brain. This delayed response explains why severe encephalitis is common even in people without underlying health conditions.

Using artificial intelligence (AI) in breast cancer screening can reduce the number of cancers diagnosed in late stages by 12 percent, according to a major new study from Sweden.

The study found that fewer women in the AI group were diagnosed with breast cancer in the years after screening. There were 1.55 cancers per 1,000 women in the AI-supported group, compared with 1.76 per 1,000 in the standard screening group.

According to lead author Dr Kristina Lang of Lund University in Sweden, this indicates better early identification of clinically relevant cancers. She said of the results: “Our findings show that AI-supported screening improves the early detection of breast cancers that are more likely to become aggressive or advanced.

“This results in fewer serious cancers being diagnosed in the interval between screenings.”

She added that wider adoption of AI-supported mammography could ease workforce pressures on radiologists while improving early detection, including of aggressive cancer subtypes.

What Did The Study Find?

The study, published in The Lancet, involved around 100,000 women who took part in routine mammography screening between April 2021 and December 2022, making it the first large randomised trial to assess how AI performs in real-world breast cancer screening.

Women were randomly divided into two groups. One group received standard screening, where mammograms were read by two radiologists and the other group had AI-supported screening, where an AI system assessed the scans first.

Low-risk cases were read by one radiologist, while higher-risk cases were checked by two, with the AI also flagging suspicious areas.

The results showed that 81 percent of cancers in the AI-supported group were detected during screening, compared with 74 percent in the standard screening group—a nine percent increase. Importantly, false-positive rates remained similar, at 1.5 percent in the AI group and 1.4 percent in the control group.

Despite positive results, Dr Lang cautioned that introducing AI into healthcare must be done carefully, using validated tools and continuous monitoring to understand how performance may vary across regions and over time.

Breast Cancer: A Rising Crisis

About 1.9 lakh Indian women are diagnosed with breast cancer annually, meaning that a new case is diagnosed every four minutes. On average, a woman in India dies of breast cancer every eight minutes, highlighting how urgently the country needs stronger awareness, early diagnosis and sustained care.

One factor that sets India apart is the age at which women are affected. Almost half of all breast cancer patients in the country are younger than 45. This is a much higher proportion than seen in many Western nations, where the disease is usually detected later in life.

Moreover, sedentary habits, excessive consumption of processed foods as well as alcohol and smoking promotes obesity and hormonal changes which pave the way for breast cancer development.

During today's Union Budget, Finance Minister Nirmala Sitharaman announced multiple initiatives and a staggering ₹1,62,671 crore to increase agricultural production in the country

Sitharaman, who was presenting her ninth consecutive budget, said the government will support the growth of high-value crops such as coconut, sandalwood, cocoa and cashew in coastal regions, agarwood in the North East and nuts,s including walnuts, almonds and pine nuts.

Dedicated programmes will focus on rejuvenating old orchards, expanding high-density cultivation and promoting value addition by engaging rural youth, while new coconut promotion schemes aimed at boosting productivity will be launched.

She noted: "India is the world’s largest producer of coconuts. About 30 million people, including nearly 10 million farmers, depend on coconuts for their livelihood. To further enhance competitiveness in coconut production, I propose a Coconut Promotion Scheme to increase production and enhance productivity through various interventions 16 including replacing old and non-productive trees with new saplings/plants/varieties in major coconut growing states.”

And health experts across the country say that an increase in consumption of these food items can significantly help improve your health.

Dr Sunil Kutty, Director and Consultant Brain and Spine Surgeon, NewEra Hospitals, Navi Mumbai, exclusively told Healthandme: "The Union Budget emphasises improving national nutrition and food security, recognising that better diets are foundational to health and well‑being.

"By strengthening food systems, supporting high‑value crops and enhancing access to nutrient‑rich foods, the government aims to reduce malnutrition, micronutrient deficiencies and diet‑linked diseases like Type-2 diabetes, obesity, and cardiovascular diseases. Integrating nutrition‑focused initiatives with healthcare can lower the overall burden of non‑communicable conditions and improve immunity, especially among children, women and vulnerable groups.

"These measures also support rural livelihoods, increasing access to affordable, healthy food across socio‑economic groups, contributing to long‑term health outcomes and reduced healthcare costs."

Coconut: Prevents Cell Damage And Packed With Essential Minerals

When eaten in moderation, coconuts offer healthy fats (MCTs), fibre, manganese, copper, iron, potassium as well as ample of antioxidants. Potassium helps balance sodium levels in the body and potentially lowers blood pressure, while the fruit's high fibre content supports bowel health and prevents constipation.

Coconuts are also especially high in manganese, which is essential for bone health and the metabolism of carbohydrates, proteins, and cholesterol. Along with this, they’re also rich in copper and iron, which help form red blood cells, as well as selenium, an important antioxidant that protects your cells and reduces cell damage which can prevent future cancer development.

A 2020 case study found that supplementing with coconut oil helped lower blood sugar levels in a person with diabetes, a condition characterized by unstable blood sugar levels. The researchers suggest that these effects may be due to the coconut’s anti-inflammatory properties and antioxidant content.

A 2024 animal study also found that consuming coconut water after eating could help manage blood sugar levels. This could be due to bioactive compounds like ellagic acid, butin, and quercetin, among others.

Sandalwood: Skin Benefits and Anxiety Reduction

Sandalwood offers benefits for skin health (acne, ageing, brightening), mental well-being, aid sleep, and possesses anti-inflammatory, antiseptic as well as antibacterial properties, making it useful for skin irritations, respiratory issues, and even potentially lowering blood pressure.

A 2017 Sigma study suggests that lavender, sandalwood, and orange-peppermint aromatherapy helped reduce self-reported feelings in anxiety of 87 women undergoing a breast biopsy.

In a 2016 pilot study published in NPC of 32 people in Vienna, Austria, participants inhaled lavender and sandalwood oil. The study found that the participants’ blood pressure levels were lower and that the cortisol levels in their saliva were lower after the aromatherapy.

Cocoa: Boosts Heart Health

While cocoa is most famous for its role in chocolate production, it is also packed with polyphenols and reduces high blood pressure by improving nitric oxide levels.

Researchers have previously linked polyphenols to numerous health benefits, including reduced inflammation, lower blood pressure and better heart health. It also contains flavanols, which have potent antioxidant and anti-inflammatory effects.

The flavanols in cocoa also improve nitric oxide levels in the blood, which can enhance the function of the blood vessels and reduce blood pressure.

Nuts: Improve Overall Health

Over time, this can improve artery health, lower bad LDL cholesterol, and reduced risk of blood clots, with varieties like almonds, walnuts, and pistachios providing unique nutrients like omega-3s, antioxidants and selenium.

Lastly, Pattabhi Rama Rao, Managing Director, Gourmet Popcornica also noted to Healthandme: "These measures, combined with stronger market linkages and local enterprise development, can make wholesome foods more affordable and accessible, directly supporting better nutrition and overall public health outcomes across the country. Not just this, farmers being able to access equitable income will enable them to access high-quality, nutritious food.

"By prioritising high-value and nutritious crops like coconut, cashew, cocoa, and walnuts, the government is not just enhancing farmers’ incomes but also ensuring that healthier, nutrient-rich foods are more widely available to the public.

"Diversifying production through fisheries, livestock, and region-specific crops, like maize in Andhra Pradesh and Chhattisgarh, will improve access to proteins, healthy fats, and essential micronutrients, which are vital for balanced diets.
