A new simulation by Finnish researchers showing how far viruses spread when a single person coughs is a startling reminder as to why we should do our best to stay home.
The 3D model was published on Thursday, April 9, on Finland’s Aalto University YouTube channel and has already been viewed more than 750,000 times. In the minute-long video, a person coughs out aerosol particles in a corridor bounded by shelves, much like at a normal grocery or supermarket.
Within two minutes, the air-borne particles spread over to the adjacent corridor. The simulation takes into account normal indoor ventilation air conditions, and also show how high particles travel with a colour-coded representation.
Aerosol particles from a dry cough, which is a symptom of Covid-19, are less than 15 micrometers, so small that they drift through the air rather than sink to the floor.
“Someone infected by the coronavirus, can cough and walk away, but then leave behind extremely small aerosol particles carrying the coronavirus,” Ville Vuorinen, assistant professor at Aalto University, said in a statement. “These particles could then end up in the respiratory tract of others in the vicinity.”
The study, conducted by researchers from a number of Finnish universities, aims to find out how the coronavirus spreads through the air. “Preliminary results indicate that aerosol particles carrying the virus can remain in the air longer than was originally thought,” the statement by Aalto University reads. “So it is important to avoid busy public indoor spaces.”

Who was Alfred Nobel?
The Nobel Prize was created by wealthy Swedish chemist and entrepreneur Alfred Nobel.
- In his will he dictated that the bulk of his estate should be used to fund "prizes to those who, during the preceding year, have conferred the greatest benefit to humankind".
- Nobel is best known as the inventor of dynamite, but also wrote poetry and drama and could speak Russian, French, English and German by the age of 17. The five original prize categories reflect the interests closest to his heart.
- Nobel died in 1896 but it took until 1901, following a legal battle over his will, before the first prizes were awarded.

Explainer: Tanween Design Programme
Non-profit arts studio Tashkeel launched this annual initiative with the intention of supporting budding designers in the UAE. This year, three talents were chosen from hundreds of applicants to be a part of the sixth creative development programme. These are architect Abdulla Al Mulla, interior designer Lana El Samman and graphic designer Yara Habib.
The trio have been guided by experts from the industry over the course of nine months, as they developed their own products that merge their unique styles with traditional elements of Emirati design. This includes laboratory sessions, experimental and collaborative practice, investigation of new business models and evaluation.
It is led by British contemporary design project specialist Helen Voce and mentor Kevin Badni, and offers participants access to experts from across the world, including the likes of UK designer Gareth Neal and multidisciplinary designer and entrepreneur, Sheikh Salem Al Qassimi.
The final pieces are being revealed in a worldwide limited-edition release on the first day of Downtown Designs at Dubai Design Week 2019. Tashkeel will be at stand E31 at the exhibition.
Lisa Ball-Lechgar, deputy director of Tashkeel, said: “The diversity and calibre of the applicants this year … is reflective of the dynamic change that the UAE art and design industry is witnessing, with young creators resolute in making their bold design ideas a reality.”

How to wear a kandura
Dos
- Wear the right fabric for the right season and occasion
- Always ask for the dress code if you don’t know
- Wear a white kandura, white ghutra / shemagh (headwear) and black shoes for work
- Wear 100 per cent cotton under the kandura as most fabrics are polyester
Don’ts
- Wear hamdania for work, always wear a ghutra and agal
- Buy a kandura only based on how it feels; ask questions about the fabric and understand what you are buying
'Worse than a prison sentence'
Marie Byrne, a counsellor who volunteers at the UAE government's mental health crisis helpline, said the ordeal the crew had been through would take time to overcome.
“It was worse than a prison sentence, where at least someone can deal with a set amount of time incarcerated," she said.
“They were living in perpetual mystery as to how their futures would pan out, and what that would be.
“Because of coronavirus, the world is very different now to the one they left, that will also have an impact.
“It will not fully register until they are on dry land. Some have not seen their young children grow up while others will have to rebuild relationships.
“It will be a challenge mentally, and to find other work to support their families as they have been out of circulation for so long. Hopefully they will get the care they need when they get home.”
