38 átomos de antimatéria

No CERN de Genebra foram criados os primeiros átomos de antimatéria realizados em laboratório.
Foram 38 átomos de anti-hidrogênio, dentro de uma cápsula, quase "imobilizados", mantidos em baixíssima temperatura em uma espécie de "armadilha magnética" por quase 2 décimos de segundo no vácuo.
O experimento internacional denominado Alpha, foi publicado na Nature ontem.
Ele é fundamental para o entendimento da ruptura da simetria do Universo, de como em um estado primordial de perfeito equilíbrio entre matéria e antimatéria, a primeira prevaleceu no Big Bang.

Real beauty tips

The following was written by the late educator-humorist Sam Levinson for his grandchild and read by Audrey Hepburn on Christmas Eve, 1992. It was also used by Ms. Hepburn on occasion when she was asked for beauty tips. [From Audrey Hepburn by Barry Paris, 1996, Putnam]

For attractive lips, speak words of kindness.
For lovely eyes, seek out the good in people.
For a slim figure, share your food with the hungry.
For beautiful hair, let a child run his or her fingers through it once a day
For poise, walk with the knowledge that you never walk alone.
People, even more than things, have to be restored, renewed, revived, reclaimed and redeemed; never throw out anyone.
Remember, if you ever need a helping hand, you'll find one at the end of each of your arms.
As you grow older, you will discover that you have two hands, one for helping yourself, the other for helping others.
The beauty of a woman is not in the clothes she wears, the figure that she carries or the way she combs her hair.
The beauty of a woman must be seen from in her eyes, because that is the doorway to her heart, the place where love resides.
The beauty of a woman is not in a facial mode but the true beauty in a woman is reflected in her soul. It is the caring that she lovingly gives the passion that she shows. The beauty of a woman grows with the passing years.
