"Chinese scientists estimated that Sars-CoV-2 had on its surface 26 spike proteins that could bind with a host cell. Researchers at Cambridge University in Britain gave a similar estimate of 24. A study by researchers in the Max Planck Institute in Germany came up with a count of 40. [Hungarian researchers] there were 61 spikes on their specimen. This suggested the variability of the viral structure could be greater than thought ...
They poked the spike proteins with the needle and found they were swinging rapidly at high frequency. The atomic camera could take more than 300 shots in a second but still only got a motion-blurred image of the spikes. Such high speed movements could help the virus more easily find and hook onto a host cell ...
A study by French scientists in April found that the virus could replicate in animal cells after being exposed to a temperature of 60 degrees Celsius for an hour. The massive outbreaks in some countries over the northern hemisphere summer also suggested that high temperature did not slow the spread of the pandemic as previously hoped. ... heated the viral particle to 90 degrees for 10 minutes and found that “remarkably, their global appearance was only slightly altered”"

This is probably one of the underlying research papers:
