America’s first President, General George Washington, remarked that all men must “Labor to keep alive in our breast that little spark of celestial fire we call Conscience.”
But there are other celestial fires that spark and burn deep in our souls.
The late funnyman who, as we found out, was near enough a manic-depressive, Robin Williams, remarked that “we’re only given that little spark of madness, and that we mustn’t lose it”.
I’ve always preferred to believe in the adage I’d heard since childhood that a ‘spark of kindness can start a fire of love’.
‘Fires of love’: What an apt description for the burning desire that a man finds overtaking all his senses when, finally, he meets The One, the most wonderful woman on the planet, and he will give his all to woo and win her.
Who knew that passions really do ‘spark’, and at a level which is, after all, truly what the most-lasting love is all about?
Bright Flash of Light Marks Incredible Moment Life Begins When Sperm Meets Egg
Human life begins in bright flash of light as a sperm meets an egg, scientists have shown for the first time, after capturing the astonishing ‘fireworks’ on film.
An explosion of tiny sparks erupts from the egg at the exact moment of conception.
Scientists had seen the phenomenon occur in other animals but it is the first time is has been also shown to happen in humans.
“To see the zinc radiate out in a burst from each human egg was breathtaking.”, said Professor Teresa Woodruff, Northwestern University
Not only is it an incredible spectacle, highlighting the very moment that a new life begins, the size of the flash can be used to determine the quality of the fertilised egg.

The discovery could help fertility doctors pick the best fertilised eggs to transfer during in vitro fertilisation (IVF).
“It was remarkable,” said Professor Teresa Woodruff, one of the study’s two senior authors and an expert in ovarian biology at Northwestern.
“We discovered the zinc spark just five years ago in the mouse, and to see the zinc radiate out in a burst from each human egg was breathtaking.
“This means if you can look at the zinc spark at the time of fertilization, you will know immediately which eggs are the good ones to transfer in in vitro fertilization.
“It’s a way of sorting egg quality in a way we’ve never been able to assess before. “All of biology starts at the time of fertilization, yet we know next to nothing about the events that occur in the human.”
Currently around 50 per cent of fertilised eggs do not develop properly and experts believe that faulty genetic code could be responsible.
Some clinics take videos of the egg developing to try pick up problems early, while others check for genetic mutations, but that is an invasive procedure which can damage the tiny egg. Often it is just down to a clinician decided which eggs look the healthiest.
But the new findings could give and extra indication that an egg is flourishing. A video of nine human eggs coming into contact with sperm enzyme showed two flashed much brighter than the rest.
“This is an important discovery because it may give us a non-invasive and easily visible way to assess the health of an egg and eventually an embryo before implantation,” said co-author Dr Eve Feinberg, who took care of the patients who provided eggs for the basic science study and collaborated with the research team.
“There are no tools currently available that tell us if it’s a good quality egg. Often we don’t know whether the egg or embryo is truly viable until we see if a pregnancy ensues.
“That’s the reason this is so transformative. If we have the ability up front to see what is a good egg and what’s not, it will help us know which embryo to transfer, avoid a lot of heartache and achieve pregnancy much more quickly.”

The bright flash occurs because when sperm enters and egg it triggers calcium to increase which releases zinc from the egg. As the zinc shoots out, it binds to small molecules which emit a fluorescence which can be picked up my camera microscopes.
Over the last six years this team has shown that zinc controls the decision to grow and change into a completely new genetic organism.
In the experiment, scientists use sperm enzyme rather than actual sperm to show what happens at the moment of conception.
“These fluorescence microscopy studies establish that the zinc spark occurs in human egg biology, and that can be observed outside of the cell,” said Professor Tom O’Halloran, a co-senior author.

In a companion paper published in Scientific Reports on March 18, a zinc spark is shown at the precise time a sperm enters a mouse egg.
This discovery was made by Zhang, a postdoctoral fellow at Northwestern. Little is known about the events that occur at the time of fertilization, because it is difficult to capture the precise time of sperm entry.
The study will be published April 26 in “Scientific Reports.” [End Quote]
As at least some of you regular readers know, my life runs on soundtracks which seem to be produced from somewhere deep in my soul and which ‘sync’ with what’s going on around me.
Reading this ‘sparked’ thoughts about the majesty of Life, the crescendo of a loving relationship between a husband and wife which creates their flesh realized as the gift of a child.
Amongst music’s best of the steadily, passionately building crescendo which takes Life to another level of glorious explosion is the late French composer Camille Saint-Saens’ Symphony Number 3.
Commonly known as the ‘Organ Symphony‘, SaintSaens himself admitted that the Symphony No. 3 was his greatest work. It was his last attempt at the symphonic form, and the composer claimed that he gave he gave everything he was able to give to this masterful piece.
Even that ‘fits’, so to speak, with the anatomical discussion above.
Here’s to Love!
Here’s to Life!
Here’s to New Life and Lives to come!
This column is dedicated to one very special couple and to all parents-to-be & grandparents-to-be everywhere!
