You’re beautiful (James Blunt)
My life is brilliant
My love is pure
I saw an angel
Of that I'm sure
She smiled at me on the subway
She was with another man
But I won't lose no sleep on that
'Cause I've got a plan
You're beautiful
You're beautiful
You're beautiful, it's true
I saw your face in a crowded place
And I don't know what to do
'Cause I'll never be with you
Yes, she caught my eye
As we walked on by
She could see from my face that I was
Flying high
And I don't think that I'll see her again
But we shared a moment that will last 'til the end

From duplicate dogs to modern mammoths, cloning has come a long way since Dolly the sheep took her first tentative steps.
By David Cox22nd March 2022
On 5 July 1996, a sheep was born who would go on to inspire entire industries, provide scientists with a new way of helping endangered species, and change medical science in ways that were barely conceivable at the time.
But this was no ordinary sheep. Her very entry to the world was groundbreaking – she was cloned using cells taken from another sheep's mammary gland as part of an experiment conducted by the Roslin Institute in Midlothian, Scotland. They named her Dolly after the singer Dolly Parton.
At that point, scientists had been dabbling with cloning – the process of creating a genetically identical copy of another living being – since the 1950s, when British biologist John Gurdon found a way to clone African clawed frogs. Despite many attempts, repeating the feat in larger mammals had proven an elusive and near-impossible task.
"The cloning of Dolly the sheep showed the world that it was possible to essentially reprogramme all the DNA in the nucleus of an adult cell, so it started behaving like an embryonic cell again, giving rise to a new animal," says Robin Lovell-Badge, who heads the Stem Cell Biology and Developmental Genetics Laboratory at the Francis Crick Institute in London.

While some knowledge of morphology is required in order to divide syllables in English, no one needs to have it for this purpose, since syllable division is not common in English. Not even word processors are programmed to do that! The important thing is to know how many syllables a word has, and where the stress falls. And that is a much easier task to accomplish.
In Portuguese, the number of syllables a word has usually equals the number of vowels letters; that is, we practically pronounce all the letters we write. In English, the number of syllables equals the number of vowels sounds, because we don’t pronounce all letters we write.
