#PELÉ & JATENE (link para mais) Em memória de nosso Rei, rescém falecido...

Publicado: Zero Hora 17 de janeiro de 1995 (3a. feira)

Aloyzio Achutti,  médico e professor universitário

            Há dois anos (1993) quando chegávamos, eu e dra.Valderês, a um hotel numa cidadezinha perto do círculo polar ártico, ao nos identificarmos como brasileiros, o porteiro exclamou "You are from the country of the king!" (vocês são da terra do rei). Eu só o entendí quando ele foi mais explícito: "the king Pelé!"

            Vinhamos da 3a. Conferência Mundial sobre Cardiologia Preventiva em Oslo, onde fora figura de destaque uma campeã mundial da Noruega. Por tê-la acompanhado em "jogging" matinal, até ganhamos camisetas com sua assinatura, dizendo "eu corro com Gute Waitz".
            Voltando, propuzemos convidar Pelé para compor nosso Comité de Prevenção, sugerindo também um rei ao presidente da Sociedade Brasileira de Cardiologia. Vejo agora que perdemos a oportunidade de ter dois trunfos no Ministério... (Foi em Trondheim, mais no link do título)

P.S. The legacy of J. Robert Oppenheimer glows a bit more brightly now that the U.S. government nullified a 1954 decision, at the height of the McCarthy era, to revoke his security clearance. (The mastermind behind the atomic bomb was suspected of being a Soviet spy.) One of Oppenheimer’s other misfortunes was getting no recognition for discovering the idea of a black hole because his paper was published on the day Hitler invaded Poland. Watch the trailer for Oppenheimer, Christopher Nolan’s upcoming film on the physicist, here.

Cancer vaccines are showing promise. Here’s how they work.

A colored scanning electron micrograph of two T lymphocyte cells (yellow) attached to a cancer cell (green). T lymphocytes are a type of white blood cell and a component of the body's immune system. They recognize a specific target—an antigen—on the surface of the cancer cell and bind to it. Once a T-cell has bound to the cancer cell it can signal for other immune cells to destroy it.

The immediate goal is to create vaccines that destroy cancer cells—but some scientists are also testing vaccines that might prevent someone from developing cancer.

HDR continues to spark debate on human development in uncertain times

Since its global launch on September 8, the 2021/22 Human Development report,  “Uncertain Times, Unsettled Lives: Shaping our Future in a Transforming World” has generated a global conversation on new uncertainties gripping our society in an unprecedented way and the ways in which we could still reimagine our futures towards hope. https://vimeo.com/777167985?embedded=true&source=video_title&owner=173253422

No dia 28 p.p. tive a grata satisfação de reencontrar o eminente colega que esteve conosco e junto com Eduardo Costa na investigação epidemiológica de 1978, que teve como objeto a população adulta de nosso Estado. Veio com sua filha Cecília. Mora em Genebra, onde trabalhou até se aposentar na OMS. Há décadas  não nos encontrávamos. Atualmente é co-Diretor da International Society of Urban Health.

10 incredible James Webb Space Telescope images reveal the wonders of the universe It is no exaggeration to say the James Webb Space Telescope (JWST) represents a new era for modern astronomy.  Launched on December 25 last year and fully operational since July, the telescope offers glimpses of the universe that were inaccessible to us before. Like the Hubble Space Telescope, the JWST is in space, so it can take pictures with stunning detail free from the distortions of Earth’s atmosphere.   Continued here
