			<content:encoded><![CDATA[<p>No início do primeiro mandato de George W. Bush, foi promovida uma medida que pretendeu satisfazer as hostes mais conservadoras da base de apoio do GOP.  Contrariando as políticas anteriores de Clinton, a administração Bush passou a apoiar financeiramente campanhas de promoção da abstinência sexual de adolescentes e a deixar de financiar aquelas que apelavam à prevenção da gravidez através da contracepção.  Na altura, Britney Spears foi a figura escolhida para transmitir a ideia que as adolescentes norte-americanas deveriam esperar pelo casamento para ter sexo. Cinco anos depois, e pela primeira vez desde 1990, a taxa de crianças nascidas de mães adolescentes subiu.  O ano passado, voltou a subir novamente. Barack Obama pode afirmar &#8212; com a razão toda &#8212; que a gravidez da filha <em>teenager</em> de Sarah Palin é um assunto do foro da família da candidata a vice de McCain, mas é impossível mantermo-nos indiferentes à ironia.</p>

<p>por <a href="https://www.msu.edu/~mcalpin9/lhc_rap/largehadron.html" target="_blank">Kate McAlpine</a>, Michigan State University</p>
<p><em>Twenty-seven  kilometers of tunnel under ground<br />
Designed with mind to send protons around<br />
A  circle that crosses through Switzerland and France<br />
Sixty  nations contribute to  scientific advance<br />
Two  beams of protons swing round, through the ring they ride<br />
‘Til in the hearts  of the detectors, they’re made to collide<br />
And all that  energy packed in such a tiny bit of room<br />
Becomes mass,  particles created from the vacuum<br />
And then…</em></p>
<p><em>LHCb  sees where the antimatter’s gone<br />
ALICE looks at collisions of lead ions<br />
CMS  and ATLAS are two of a kind<br />
They’re looking for whatever new particles they can find.<br />
The  LHC accelerates the protons and the lead<br />
And  the things that it discovers will rock you in the head.</em></p>
<p><em>We  see asteroids and planets, stars galore<br />
We know a black hole resides at each galaxy’s core<br />
But even all that matter cannot explain<br />
What holds all these stars together – something else remains<br />
This dark matter interacts only through gravity<br />
And how do you catch a particle there’s no way to see<br />
Take  it back to the conservation of energy<br />
And the particles appear, clear as can be</em></p>
<p><em>You see particles flying, in jets they spray<br />
But you notice there ain’t nothin’, goin’ the other way<br />
You say, “My law has just been violated – it don’t make  sense!<br />
There’s gotta be another particle to make this balance.”<br />
And it might be dark matter, and for first<br />
Time we catch a glimpse of what must fill most of the known  ‘Verse.<br />
Because…</em></p>
<p><em>LHCb sees where the antimatter’s gone<br />
ALICE  looks at collisions of lead ions<br />
CMS and ATLAS are two of a kind<br />
They’re looking for whatever new particles they can find.</em></p>
<p><em>Antimatter is sort of like matter’s evil twin<br />
Because except for charge and handedness of spin<br />
They’re the same for a particle and its anti-self<br />
But you can’t store an antiparticle on any shelf<br />
Cuz when it meets its normal twin, they both annihilate<br />
Matter turns to energy and then it dissipates</em></p>
<p><em>When matter is created from energy<br />
Which is exactly what they’ll do in the LHC<br />
You get matter and antimatter in equal parts<br />
And they try to take that back to when the universe starts<br />
The Big Bang – back when the matter all exploded<br />
But the amount of antimatter was somehow eroded<br />
Because when we look around we see that matter abounds<br />
But antimatter’s nowhere to be found.<br />
That’s why…</em></p>
<p><em>LHCb sees where the antimatter’s gone<br />
ALICE  looks at collisions of lead ions<br />
CMS and ATLAS are two of a kind<br />
They’re looking for whatever new particles they can find.<br />
The LHC accelerates the protons and the lead<br />
And the things that it discovers will rock you in the head.</em></p>
<p><em>The Higgs Boson – that’s the one that everybody talks about.<br />
And it’s the one sure thing that this machine will sort out<br />
If the Higgs exists, they ought to see it right away<br />
And if it doesn’t, then the scientists will finally say<br />
“There is no Higgs!   We need new physics to account for why<br />
Things have mass.   Something in our Standard Model went awry.”</em></p>
<p><em>But the Higgs – I still haven’t said just what it does<br />
They suppose that particles have mass because<br />
There is this Higgs field that extends through all space<br />
And some particles slow down while other particles race<br />
Straight through like the photon – it has no mass<br />
But something heavy like the top quark, it’s draggin’ its  ***<br />
And the Higgs is a boson that carries a force<br />
And makes particles take orders from the field that is its  source.<br />
They’ll detect it….</em></p>
<p><em>LHCb sees where the antimatter’s gone<br />
ALICE  looks at collisions of lead ions<br />
CMS and ATLAS are two of a kind<br />
They’re looking for whatever new particles they can find.</em></p>
<p><em>Now some of you may think that gravity is strong<br />
Cuz when you fall off your bicycle it don’t take long<br />
Until you hit the earth, and you say, “Dang, that hurt!”<br />
But if you think that </em><em>force is powerful, you’re wrong.<br />
You see, gravity – it’s weaker than Weak<br />
And the reason why is something many scientists seek<br />
They think about dimensions – we just live in three<br />
But maybe there are some others that are too small to see<br />
It’s into these dimensions that gravity extends<br />
Which makes it seem weaker, here on our end.<br />
And these dimensions are “rolled up” – curled so tight<br />
That they don’t affect you in your day to day life<br />
But if you were as tiny as a graviton<br />
You could enter these dimensions and go wandering on<br />
And they&#8217;d find you&#8230;</em></p>
<p><em>When LHCb sees where the antimatter’s gone<br />
ALICE  looks at collisions of lead ions<br />
CMS and ATLAS are two of a kind<br />
They’re looking for whatever new particles they can find.<br />
The LHC accelerates the protons and the lead<br />
And the things that it discovers will rock you in the head.</em></p>

			<content:encoded><![CDATA[<p>Os Republicanos insistem em afirmar que esta campanha é sobre <em>issues</em>, embora continuem sem apresentar uma única ideia sobre o que quer que seja. O meu desejo é que John Edwards e Hillary Clinton ainda venham a desempenhar um papel de destaque na próxima administração Democrata, num dos departamentos importantes para a política interna: justiça, trabalho, saúde e interior. Afinal, uma das assinaturas das primárias Democratas do primeiro semestre de 2008 foi precisamente o debate de ideias sobre assuntos de política interna.  Muito devido a Edwards, primeiro, e a Clinton, depois.</p>

			<content:encoded><![CDATA[<p>Dos quatro debates presidenciais até Novembro, três serão entre Obama e McCain e o outro entre Joe Biden e o candidato a vice Republicano (a anunciar para a semana). Um dos debates entre os candidatos a presidente (acho que o último), será sobre política internacional.  McCain não é propriamente o mais esclarecido e informado candidato sobre o tema, mas não deixará, certamente, de chamar a atenção para o facto de o <em>especialista</em> Democrata em relações internacionais não estar sentado à sua frente.</p>
