AstraZeneca’s COVID-19 vaccine

 U.K. regulator granted emergency use authorisation of AstraZenca's Vaccine on 30.12.20 

It is based on weakened Adenovirus, i.e. a common cold flu virus  which contains genetic material of spike protein.

Can be stored and transported at 2°- 8°.

less costly then mRNA Vaccines like that of Pfizer and Moderna.

Showed 62% efficacy when 2 full strength dose administered 4 weeks apart, as per published report.

Earth's rotational speed

  “Basically a nything that moves mass towards the center of the Earth will speed up the planet’s rotation, much as a spinning ice skater speeds up when they pull in their arms”, explained Ian Sample, science editor of The Guardian.  Tidal friction slows the speed. The moon is mostly to blame for the effect: the gravitational tug slightly distorts the planet, producing tidal friction that steadily slows the Earth’s rotation. To keep clocks in line with the planet’s spin, the International Telecommunication Union, a United Nations body, has taken to adding occasional leap seconds in June or December , most recently in 2016. However, even without adding leap seconds, if Earth spins faster, it could result in GPS satellites becoming useless, as  a half-a-millisecond equates to 10-inches or 26 cm at the equator there are also potentially confusing consequences for smartphones, computers, and communications systems, which synchronize with  Network Time Protocol (NTP)...

The “Chandler Wobble”

 a lso known as the Chandler variation of latitude, the “Chandler Wobble” is a natural shifting of the Earth’s axis due to the planet not being perfectly spherical, and could be linked to the spinning speeds, three scientists wrote in The Conversation.
