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.

Colleen Hoover, the best-selling author of 'Regretting You' and 'Verity', has revealed that she has undergone treatment for cancer.

On January 12, Hoover announced via her Instagram Stories that she has one more day of radiation left at Texas Oncology.

"Second to last day of radiation," she captioned the post on her Instagram Stories. "I wish I could blame my hair and facial expressions on @Texas.Oncology, but they've been great. Hope you never need them, but highly recommend them."

In December 2025, the 46-year-old writer wrote on her Facebook page that she had been diagnosed with cancer and had undergone surgery. The film producer also noted that she would only need radiation, but not chemotherapy as a treatment plan.

Hoover said she had been in Canada filming Reminds of Him when she noticed she “had recurring health issues that I continued to put off until the movie was finished" and a check-up revealed that she had developed cancer.

What Kind Of Cancer Does She Have?

While she is yet to reveal which kind of cancer she is receiving treatment for, Hoover has confirmed it was not caused by family genes, HPV or excessive hormones.

In a Facebook post from January 9, she noted that the reason for her illness is 'more than likely' to be environmental/lifestyle, which can be credited to a lack of exercise, poor diet and stress.

"I’m happy and grateful to be alive but I hate vegetables. I hate when I have to get off the couch. I hate sweating. I hate when science is right. If you see me at the gym, don’t even tell me good job. If you see me at a restaurant eating grilled chicken and drinking water, I’m probably real mad about it," she wrote in a heartfelt moment.

Why Has Hoover Been Missing From Public Eye?

Hoover's health updates and cancer treatment come amid a series of cancelled public events. In October 2025, she announced she would not attend the premiere of Regretting You, her latest movie adaptation.

In a sentimental Instagram post, she told her fans: "I’m super bummed, but am having an unavoidable surgery and can’t travel for a while,” Hoover wrote in her Instagram post at the time. I’ll live vicariously through you guys. So sad to miss this movie release and premiere, but so grateful to all the actors and the team who put this together.”

Woman Down is Hoover’s next book release set for January 13. However, the author has had to tell fans that a book-signing tour has not been set up yet and she will not be meeting with the public for now.

“I wanted to make this post and be transparent about why that is. I’m not saying I won’t be up to doing at least one signing, but I just won’t know until I know," she said.

Meanwhile, throughout 2025, production on her hit novel, Verity, has begun in 2025, with Anne Hathaway and Josh Hartnett, being photographed during scenes last February. Additionally, her third movie adaptation, Reminders of Him, is also set to hit theaters on March 13, 2026.

It remains unknown if she will be attending the premiere for Reminders of Him.

Barbie. A name too familiar for everyone growing up, now Mattel Studio has launched its first autistic Barbie. This is after Greta Gerwig's 2023 blockbuster movie that introduced the concept of diverse characters of Barbie, that Mattel launched its first Barbie with type 1 diabetes. The studio is definite about creating a diverse range of Barbie character, as an animated Barbie film too is in the development.

Why Is The Launch Of Autistic Barbie Important?

Autistic Barbie is the latest addition to Barbie's Fashionistas range, which is designed so more children can "see themselves in Barbie". The Barbie is created in collaboration with the US charity the Autistic Self Advocacy Network. The Barbie is designed to represent the ways autistic children may have experienced, including the way they communicate.

Barbie With Autism: What Are Her Features?

The Barbie's eyes gaze slightly to one side, which could represent how some autistic people avoid direct eye contact. The Barbie also comes with completely bendable elbows and wrists, which enables her repetitive physical movements such as stimming and hand-flapping that help people with autism to process sensory information, or even express excitement.

She also holds a pink fidget spinner on her finger, which helps her reduce her stress, wears noise-cancelling headphones, also in pink, to reduce sensory overload, and carries a pink tablet with symbol-based augmentative and alternative communication buttons on its screen that helps with her everyday communication.

Barbies earlier came in one-size-fit-all, often lacking the diversity and representation, this Barbie, however, wears a loose-fitting purple pinstripe A-line dress. This has minimized fabric to skin contact, and her shoes have flat soles that promotes stability and ease of movements.

Barbie's Representation Matters

The first Barbie came in 1959, and until 2019, there were no dolls with disabilities. Now, there are Barbies with diabetes, blind dolls, and Barbies with wheelchairs, Down syndrome, prosthetic limb, vitiligo, and hearing aids. There is also a Ken doll with a prosthetic leg, and another one who uses a wheelchair with a ramp, and one with hearing aids.

Jamie Cygielman, the global head of dolls at Mattel while announcing the autistic Barbie said, "Barbie has always strived to reflect the world kids see and the possibilities they imagine, and we’re proud to introduce our first autistic Barbie as part of that ongoing work. The doll helps to expand what inclusion looks like in the toy aisle and beyond because every child deserves to see themselves in Barbie."

She also added: “We engaged with the autistic community throughout the design process, always mindful that autism is experienced differently by every individual and is not always visible. The elements of this doll reflect how some people on the spectrum may experience and express the world, and we hope that by partnering with influential voices within the community, Barbie can continue to showcase a broader range of authentic experiences.”

What Is Autism?

As per the American Psychiatric Association, ASD is a complex developmental condition involving persistent challenges with social communication, restricted interests and repetitive behavior. While autism is considered a lifelong condition, the need for services and supports because of these challenges varies among individuals with autism.

As per the Centers for Disease Control and Prevention, an estimated one in 36 children have been identified with ASD.

The Department of Health (DOH) reported 411 measles infections in Philippines' Northern Mindanao in 2025, which was a 11% increase from 371 cases in 2024. Health officials are now warning people that the situation may get worse in 2026, as rate of unvaccinated children in the region also rise.

In 2025, 75% of the patients were unvaccinated.

In order to prevent outbreaks, DOH-Northern Mindanao and local health offices said that they will be deploying teams to administer Measles-Rubella (MR) vaccines to children and people aged six to 59.

“There are (measles) outbreaks in various parts of the country because of low (immunization) coverage and that includes our region,” said Germaine Labadan, head of the DOH-X Family Health Cluster.

In 2025, only 56.7% of Northern Mindanao's eligible population received MR shots, which led to a herd immunity well below the target of 95%.

Cagayan de Oro, a highly urbanized city, recorded the region’s highest measles-rubella (MR) coverage at 87.21%, while Bukidnon lagged at 49.71%. Coverage in other areas remained low, with Misamis Oriental at 51.87%, Misamis Occidental at 52.05%, Iligan at 52.55%, and Camiguin at 53.73%.

As part of this year’s Measles-Rubella Supplemental Immunization Activity (MR-SIA), children will be given booster MR vaccines along with Vitamin A supplements. The 21-day campaign will run from January 19 to February 13.

“This is open to all eligible, regardless of the immunization status of the child because the vaccine serves as a booster,” Labadan said. This also includes children who completed the first and second doses. “Parents may present the immunization booklet, but it is not necessary because all will be given a new one,” she said.

What Is Measles?

Measles, also known as rubeola, is a highly contagious viral illness that typically causes fever, cough, a runny nose, red and watery eyes, and a distinctive red, blotchy rash that usually begins on the face and spreads downward. The virus spreads through the air when an infected person coughs or sneezes and can lead to serious complications such as pneumonia or brain inflammation. Despite its severity, measles is preventable through a safe and effective vaccine, as per the Mayo Clinic.

How Contagious Is Measles?

Measles is among the most contagious diseases in the world. The virus spreads through airborne droplets that can linger in the air or on surfaces for hours. Up to 90% of unvaccinated people who are exposed to measles will become infected. A single infected person can pass the virus to an estimated 12 to 18 others through close contact or shared spaces. People can transmit the virus days before symptoms become obvious and continue spreading it after the rash appears, according to the World Health Organization.

How Long Is Someone Contagious With Measles?

Someone infected with measles can spread the virus from four days before the rash develops to four days after it appears. The virus spreads so efficiently that about 90% of people who are unvaccinated or have never had measles will become infected after being exposed.

In November, Canada lost its measles elimination status following a significant outbreak, according to the Pan American Health Organization, which works closely with the World Health Organization.

“It’s important to say that all the other 34 countries in the region, they keep their certification as measles-free,” said PAHO/WHO Director Dr. Jarbas Barbosa at the time, as per NPR News.

U.S. health officials have also warned that genetic links between outbreaks in different states suggest continued spread.

“The trajectory that we’re looking at now is that we do anticipate more cases well into January,” Bell said. “What that means for us nationally in terms of how they are defining our designation in this country as having eliminated measles is unclear.”
