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.

A tiny infection under a newborn’s fingernail turned out to be an important clue that led doctors to an unexpected and life-threatening diagnosis of an aggressive brain tumour.
Joey Sharp, from Penicuik in Midlothian, Scotland, was just 11 days old when his parents took him back to hospital after he began struggling to feed, losing weight and developing persistent jaundice. He was also showing signs of twitching intermittently.
While examining the newborn, doctors noticed what appeared to be a very small infection in one of his fingernails. According to Joey’s mother, Sam Sharp, the abnormality was so tiny that it looked almost like a grain of sand beneath the nail.
But while doctors were investigating the problem, an ultrasound revealed a tumour in Joey’s brain.
The discovery came as Joey’s other symptoms were becoming increasingly concerning. What initially looked like a minor problem with his finger became part of a much larger medical investigation.
Joey was subsequently diagnosed with glioblastoma, an aggressive form of brain cancer.

The nail infection itself was not reported as the cause of the brain tumour. Rather, investigating the unusual finding was part of the baby's broader medical assessment after he returned to hospital with several unexplained symptoms.
In newborns, symptoms can sometimes be difficult to interpret because babies cannot describe what they are experiencing. Problems such as poor feeding, weight loss, jaundice, and abnormal movements can have many possible causes.
In Joey's case, doctors' investigations ultimately led them to perform imaging that uncovered the brain tumour.
The story is therefore less about a nail infection “causing” a brain tumour and more about how an apparently minor physical finding helped doctors continue investigating a very sick newborn until they found the underlying problem.

For Joey, treatment was intensive. He underwent three brain surgeries and nine rounds of chemotherapy. Two operations were performed to remove the tumour, while a third was needed to deal with scar tissue that was preventing medication from controlling his seizures.
At one point, Joey was experiencing more than 30 epileptic seizures a day and required feeding tubes.
In babies, brain tumours may announce themselves through changes in head growth, feeding, alertness, vomiting or development rather than the classic headaches adults experience. According to reports on congenital glioblastoma, possible signs include:
Despite the severity of his illness and the treatment he required as a baby, Joey survived. He also participated in clinical trials designed to help researchers better understand how chemotherapy can be used to treat babies with brain tumours. He is now reported to be cancer-free.

In a world first, an experimental treatment has been administered to a 26-year-old woman, the daughter of American hedge fund manager Bill Ackman, in which mitochondria from her leg were injected into her eyes.
While the treatment did not restore vision, it produced a temporary return of the pupils’ response to light, offering a potentially important finding, according to scientists from the Icahn School of Medicine at Mount Sinai in a paper published as a preprint on Research Square.
The eye study, posted as a preprint on August 10, has not yet undergone peer review. The treatment remains highly experimental and involved only one patient.
“It was my daughter. Mitochondria has amazing potential,” Ackman said in a post on X, adding that the family had seen a sustained benefit from the initial injection, although it was weaker than the immediate response.
In February this year, Ackman’s daughter Lucy collapsed in her Brooklyn apartment after suffering a brain hemorrhage, leaving her unable to move, speak or see, the billionaire said in a post on X.
While doctors performed emergency surgery, the injury damaged her optic nerve and left her unable to see. Her pupils also stopped responding to light.
Despite the progress in other areas, Lucy’s vision has remained severely affected.
After receiving emergency approval from the US Food and Drug Administration, doctors at Mount Sinai extracted mitochondria — the energy-producing structures inside cells — from Lucy’s leg muscle and injected them into the fluid of both eyes, according to Nature.
“Over the last six months, she has recovered her cognition – she understands everything including her circumstance – is able to walk a hundred or more steps at a time with assistance, is making progress with sounds, vowels and consonants and the beginnings of speech, but she remains unable to see,” Ackman said.
The researchers reported that Lucy, who had optic nerve damage in both eyes for three months, received one mitochondrial injection in each eye, 24 hours apart.
Importantly, neither eye developed inflammation. Within days of the injections, her pupils began responding to light again — something that had not happened in 45 tests over the previous 71 days.
She also reported seeing shapes and shadows through her left eye.
However, the response faded after about four weeks, and the treatment did not restore normal vision.
“We are working on a method to inject her eyes with more frequency,” Ackman wrote on X.
According to the researchers, mitochondrial transplantation involves delivering healthy, functioning mitochondria into tissue where the mitochondria have been damaged.
The approach has been studied in the human heart and brain, but had not previously been used in the eye.
"To our knowledge, this is the first administration of isolated mitochondria to the human eye. The procedure was performed to the filed specification in both eyes," the researchers said in the paper.
Retinal ganglion cells, which are involved in transmitting visual information from the eye to the brain, depend heavily on mitochondria to produce energy. In studies involving rodents, mitochondria injected into the vitreous — the gel-like substance inside the eye — have been taken up by these cells and improved their survival after optic nerve injury.
In Lucy’s case, the injection of her own mitochondria into the eyes was reported to be safe and was associated with the temporary return of pupillary responses to light. However, it did not restore normal vision, and the visual response faded after about four weeks.
Because the report involves only one patient and has not yet undergone peer review, much more research is needed to determine whether mitochondrial transplantation could eventually become a treatment for optic nerve damage or other forms of vision loss.

The US Food and Drug Administration has approved a new breast cancer treatment that aims to act on signs of treatment resistance before the cancer starts progressing.
The US FDA has granted accelerated approval to Etcamah (camizestrant), in combination with a CDK4/6 inhibitor, for adults with hormone receptor-positive, HER2-negative locally advanced or metastatic breast cancer whose tumours develop an ESR1 mutation while being treated with an aromatase inhibitor and a CDK4/6 inhibitor.
The new approach uses a blood test to detect circulating tumour DNA (ctDNA) carrying an ESR1 mutation. If the mutation is detected, doctors can switch treatment to camizestrant rather than waiting for visible disease progression on scans.
The FDA described this as its first cancer therapy approval guided by detection of a resistance mutation in circulating tumour DNA before imaging shows progression of the disease.

The approval was based on results from the Phase III SERENA-6 trial, which included 315 patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer.
All participants were receiving an aromatase inhibitor plus a CDK4/6 inhibitor as their initial endocrine based treatment and had no evidence of disease progression when an ESR1 mutation was detected through blood testing.
Patients were randomly assigned to either switch to camizestrant while continuing their CDK4/6 inhibitor or continue their existing aromatase inhibitor with the CDK4/6 inhibitor.
Survival period without progression was 16 months with camizestrant compared with 9.2 months with standard treatment. The risk of disease progression or death was reduced by 56% with the camizestrant combination.

ESR1 mutations are one way hormone receptor-positive breast cancers can adapt to treatment. According to the FDA, fewer than 5% of patients have an ESR1 mutation when HR-positive metastatic breast cancer is first diagnosed. After disease progression on an aromatase inhibitor, however, the mutation is found in nearly 40% of patients.
This means that detecting the mutation earlier could potentially give doctors a chance to change treatment while the cancer is still controlled.
Dr Kevin Kalinsky, an investigator on SERENA-6, said, "The approach allows doctors to change treatment at an earlier opportunity ahead of disease progression rather than waiting until the cancer becomes harder to treat."
The FDA approval is accelerated, meaning continued approval may depend on confirmatory studies that will verify clinical benefit.
The regulator specifically noted that it has not yet been established whether intervening when an ESR1 mutation is detected, before radiographic progression, ultimately translates into a meaningful overall survival benefit.
The FDA has simultaneously approved the Guardant360 CDx blood test as a companion diagnostic to identify patients whose tumours carry the relevant ESR1 mutations.
The significance of the approval therefore goes beyond a new drug. It represents a shift toward using molecular clues in the bloodstream to detect treatment resistance and change therapy before cancer progression becomes visible on a scan.
