‘One of the main questions I get asked is "Is it real?"’ says Ole Bielfeldt, 20, from Cologne, Germany.
Like many people, he turned to video app TikTok to keep himself entertained during the pandemic. With no expectations, he posted a video and woke up to 7 million views 1/6
As @macrofying, Bielfeldt's photography videos zoom into ordinary, inanimate objects, revealing what we can’t see through the naked eye 2/6
‘I started the TikTok channel about a year ago, so it’s not that old. I’ve always been interested in photography and especially the different perspectives you could create.’ He decided to post one of his videos on the app - and reached 400,000 views in just a couple of hours 3/6
Bielfeldt, who now has 5.6 million followers on TikTok, thinks people's fascination with his videos are fueled by their desire to know more about how things work. He chooses everyday objects: ‘People want to understand what a T-shirt or a coffee is made out of’ 4/6
Young users on the video-sharing app tune in by the millions to watch Bielfeldt’s camera zooming into a human hand or a ponytail. He captures these unique images by attaching his camera to a microscope 5/6
He hopes his @macrofying videos make people more aware of the little things and introduce them to a totally new perspective. ‘You can go into this macro world of things that you don’t see every day’ 6/6

The COVID-19 vaccine from Pfizer and BioNTech was able to neutralize a new variant of the coronavirus spreading rapidly in Brazil, according to a laboratory study published in the New England Journal of Medicine reut.rs/3brKMjl
Blood taken from people who had been given the vaccine neutralized an engineered version of the virus that contained the same mutations carried on the spike portion of the highly contagious P.1 variant first identified in Brazil, the study found
The scientists said the neutralizing ability was roughly equivalent the vaccine’s effect on a previous less contagious version of the virus from last year.
The spike, used by the virus to enter human cells, is the primary target of many COVID-19 vaccines
