The coronavirus’s shape has an impact on how it spreads

Since the start of the COVID-19 epidemic, images of the coronavirus SARS-CoV-2 have been permanently implanted in our minds. However, the virus is not exactly shaped like a sphere with spikes as we typically imagine it. Images taken under a microscope of infected tissues reveal coronavirus particles to be ellipsoidal in shape and to have a variety of compressed and elongated morphologies.

Researchers from Queen’s University in Canada and the Okinawa Institute of Science and Technology (OIST) in Japan are leading a global study team that has examined how different elliptical shapes affect how viral particles rotate within fluids, affecting how easy the virus can spread. Recent publication of the study in the journal Physics of Fluids.

According to Professor Eliot Fried, head of OIST’s Mechanics and Materials Unit, when coronavirus particles are breathed in, they move around inside the nose and lungs. “We want to know how mobile they are in these surroundings,” the researcher said.

The speed at which particles rotate as they move through the fluid is controlled by rotational diffusivity, a particular type of movement that the scientists modelled (in the case of the coronavirus, droplets of saliva). Fluid drag is reduced and rotation speed is increased in smoother, more hydrodynamic particles. The ability of coronavirus particles to bind to and infect cells is influenced by their rotating speed.

In their research, the scientists modelled both prolate and oblate ellipsoids of revolution. Prolate shapes have one longer axis and oblate shapes have one shorter axis, which sets them apart from spheres (which have three axes of equal length). Prolate shapes grow into rod-like shapes when followed to their logical conclusion, whilst oblate shapes contract into coin-like shapes. On the other hand, coronavirus particles differ in a more subtle way.

The scientists improved the ellipsoids’ surface by coating them with spike proteins to create the most accurate model yet. The inclusion of triangular-shaped spike proteins slows the rotation of coronavirus particles, potentially increasing the virus’ ability to infect cells, according to earlier research from Queen’s University and OIST.

Each spike protein was represented by a single sphere on the surface of the ellipsoids in the scientists’ simplified model of the spike proteins.

At order to determine the arrangement of the spikes on the surface of each ellipsoidal shape, Dr. Vikash Chaurasia, a postdoctoral researcher in the OIST Mechanics and Materials Unit, explained, “We then assumed that they all have the same charge. Similar charge spikes reject one another and seek out as much space as possible. They consequently surround the particle evenly, minimising its repulsion.

The researchers’ model revealed that a particle rotates more slowly the further it deviates from a spherical shape. This would suggest that the particles have improved alignment and cell-attachment abilities.

The model is still crude, the researchers acknowledge, but it advances our knowledge of the coronavirus’s transport characteristics and may help identify a factor that is crucial to the success of its infective process.

Amitabh Bachchan: Shocking Fan Incident Outside Jalsa

Amitabh Bachchan Fan Faints After Hours of Torturous Waiting

The weekly Sunday rite outside the renowned gates of Jalsa is nothing short of profoundly holy. For decades, thousands of deeply moved admirers have gathered like clockwork, hoping for a single glimpse of the iconic megastar.

Yesterday evening, that fierce commitment took a scary and sad turn. A middle-aged guy, who had been standing patiently in the scorching midday sun for more than four hours, collapsed unexpectedly.

He collapsed totally into profound sleep, landing directly on the harsh, unforgiving asphalt road. The happy, chanting crowd fell silent in an instant as reality hit in.

A Heartbreaking Moment of Desperation

According to eyewitnesses, this enthusiast travelled across various states for a two-minute glimpse of his idol. His quivering hands clutched a framed vintage photograph of the superstar.

As the searing midday heat reached its zenith, acute dehydration and utter physical fatigue overtook his body. His feeble knees bowed under the crushing weight of his never-ending, frantic wait.

He fell face first to the ground before anyone could react or grab him. The enormous crowd’s collective, frightened gasp boomed over Juhu’s normally peaceful suburban streets.


Sudden Chaos Outside Jalsa’s Gates

Within seconds, total fear spread among the observers. Fellow supporters quickly dropped their homemade banners and posters, coming to the fallen man’s rescue. Someone desperately sprayed cold water upon his pale, sweating face.

The large security crew stationed outside Amitabh Bachchan’s home acted quickly. They were able to remove the rising, panicked crowd, allowing the choking sufferer to breathe easier.

An emergency ambulance was dispatched immediately, while local volunteers attempted to revive him. In a few startling moments, the atmosphere went from exhilarating exhilaration to total horror.


The Relentless Sunday Evening Madness

Every Sunday evening, the veteran actor gracefully goes onto a high podium at his grand gates. It is a renowned custom that has completely defined Bollywood fan culture over generations.

Passionate admirers will miss meals, risk heavy monsoons, and suffer harsh summer heat waves only to see him wave. It is a profound, emotional bond that defies all reasonable logic.

For this heartbreakingly loyal admirer, the powerful emotional rush combined with severe physical tiredness proved to be a highly perilous, almost lethal combination on the boiling, sweltering concrete.

Security Personnel Scramble to Prevent Tragedy

Local police officers responded promptly to the chaotic scene, attempting to manage the emotionally charged throng. Medical staff administered quick, vital first aid on the scene, examining his critically weak and decreasing pulse.

The comatose man was gingerly put onto a canvas stretcher, still clutching his prized, sweat-soaked image of the actor. He was sent to a local hospital for emergency treatment.

On-duty medics eventually confirmed that he had severe heatstroke and acute, life-threatening dehydration. Fortunately, his medical condition improved after he received repeated IV infusions and intensive, appropriate care.


A Stark Warning for Star-Worshippers

This terrible, tragic episode has generated a heated, much-needed debate about the extreme limits of celebrity worship in India. Blind passion should never result in the death of an innocent person.

Jalsa is an undisputed historical monument to love, but yesterday it served as a grim, sobering lesson. Extreme physical endurance for a brief moment can easily result in a catastrophic medical tragedy.

As thousands of passionate individuals continue to flow to Mumbai every day, the fine line between beautiful appreciation and life-threatening devotion becomes increasingly, dangerously blurred for these fragile worshippers.


Terrifying Boundaries of Human Obsession

The burning passion that motivates these ordinary folks to risk their own health is both wonderful and scary. It emphasises the megastar’s immense, godlike influence over millions of hearts.

While the legendary actor continues to express love to his devoted fans, this dangerous occurrence demonstrates that safety should always come first. No fan should have to bleed or faint on the street in order to catch a passing shadow.
