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.

Holi 2024: Inside, professional advice on overcoming a Bhang hangover
Holi 2024: We are eagerly awaiting the arrival of this festival of colors, which is quickly approaching. Every year, the nation celebrates Holi with great fanfare and extravagance. Holi commemorates the eternal love and marriage of Goddess Radha and Lord Krishna. In addition, Holi commemorates Lord Vishnu’s victory over Hiranyakashipu, highlighting the idea that good always triumphs over evil. Holi will be celebrated on March 25 this year. Holika Dahan, also known as Chhoti Holi, is observed the day before Holi. On the day of Holi, many customs and rites are observed throughout India. The cities of Barnsana and Nandgaon celebrate Lathmar Holi, whereas Vrindavan celebrates Phoolwali Holi.
Holi 2024: Here are some professional suggestions to avoid Bhang hangover, ranging from eating a balanced diet to sipping herbal tea.
During Holi, a variety of snacks and beverages are made to be enjoyed with loved ones. The colorful, crispy, and delectable Holi snacks range from gujia to rasmalai to namakpare. Thandai, a delightful concoction of milk, spices, and sweets, is the queen of the drink table. Bhang is among the primary draws of Holi. For its euphoric impact, thandai is sometimes blended with powdered paste made from the female cannabis plant’s leaves and flowers. But after the first euphoria wears off, there’s also the inevitable hangover the following morning.
Methods for overcoming a hangover
Hydrate the body: Hydration is crucial for managing a hangover caused by Bhang during Holi. Sip on lots of water to flush out toxins and replenish your body’s moisture.
Consume coconut water: Coconut water and other electrolyte-rich beverages can help replenish lost nutrients.
A balanced diet: blood sugar regulation and nausea reduction can be achieved by eating a well-balanced meal high in carbohydrates, proteins, and healthy fats.
Herbal teas and rest: Herbal teas with relaxing properties, such as peppermint or ginger, can ease stomach discomfort. Your body can mend itself by resting in a quiet, dark environment.
Limit alcohol intake: Limit your alcohol and cannabis intake to prevent symptoms from getting worse. As soon as symptoms develop or continue, get medical help.
