Cellular Communications
When we talk about ‘cellular communcations’, we are not referring to use of a cell phone, because before mobiles or cell phones there was a time when this only meant cell to cell interaction within an organ or tissue. This important cellular behaviour drives diverse functions from contracting cells in your heart muscle to the cells in your nerves.
Lightning Never Strikes Twice
Continuing our Fact or Fable series, today we take a look at the saying ‘Lightning never strikes twice’, with our Science Editor Samantha Gouldson investigating.
Lightning forms when excess amounts of positive and negative electric charge build up in storm clouds. This causes sparks, kind of like static electricity. Sometimes the sparks jump between the clouds but often they jump between the clouds and the ground.
It’s not just thunderstorms that have lightning either; snow storms, sand storms and even the clouds produced by erupting volcanoes can all cause lightning.
The idea that lightning doesn’t strike twice is a popular saying but one that it’s easy to disprove.
A Poem – Sadness is a Storm
This poem was sent to us by one of our talented young readers, 14 year old Rebekah.
Sadness is a storm.
A clap of thunder,
As you howl and wail,
Yet through it all,
You still prevail.
Nothing withstands
The heart of the tempest.
Ominous clouds loom,
Lightning flashes.
Light still gets through.
It gives you a glimpse,
Of hope pure and true
All’s well once more,
With the subsiding of the storm.
