New CMOS Camera Will Record Your Thoughts At 1,000,000 FPS
Scientists of the Megaframe project in Europe have developed a CMOS sensor so small that it can actually go inside a neuron channel and look at the thought signals in real time. Not to mention the fact that it can do so in 1024pixels and at a photon resolution too. This means that it can actually capture snapshots of photons. While this is an achievement on its own, a huge one, the practical uses of this CMOS camera are far more exciting.

Winzige Atombatterien liefern hunderte Jahre Strom
Forscher der Universität Missouri haben eine winzige Radionuklidbatterie vorgestellt, die über Millionen mal mehr Leistungskraft verfügt als herkömmlichen Batterien. Die Atombatterie kann praktisch ewig verwendet werden, die etwa münzengroßen Energiespeicher weisen eine Laufzeit von bis zu mehreren hundert Jahren auf. Die Erfindung des Forscherteams um Jae Kwon soll vor allem in Mikrosystemen (MEMS) und noch kleineren nanoelektromechanischen Systemen (NEMS) zum Einsatz kommen.

Samenflüssigkeit soll Alterung bremsen
Eine Substanz aus dem Sperma kann angeblich das Altern von Zellen aufhalten. Euphorisch sprechen einige Forscher vom "heiligen Gral der Altersforschung" - auch wenn sie ihre Erfolge bisher nur bei Zellkulturen und Organismen wie Würmern und Mäusen erzielt haben.
Graz - Spermidin findet sich in unterschiedlichen Mengen in allen Körperzellen, vor allem aber - der Name legt es nahe - in männlicher Samenflüssigkeit. Wenn ein Organismus altert, nimmt die Konzentration der Substanz stetig ab. Das vermuten jedenfalls Forscher um Frank Madeo von der Universität Graz in Österreich. Sie glauben, dass die Verbindung außerdem dabei helfen könnte, geschädigte Zellen zu reparieren.

Alan Turing Gets an Apology From Prime Minister Brown
The British government has officially apologized for the treatment of Alan Turing in the post war era. An online petition got more than enough signatures to force an official statement and Prime Minister Gordon Brown has issued a lengthy apology. 'Thousands of people have come together to demand justice for Alan Turing and recognition of the appalling way he was treated. While Turing was dealt with under the law of the time and we can't put the clock back, his treatment was of course utterly unfair and I am pleased to have the chance to say how deeply sorry I and we all are for what happened to him. So on behalf of the British government, and all those who live freely thanks to Alan's work I am very proud to say: we're sorry, you deserved so much better.

First Images From Refreshed Hubble Telescope
As tweeted, NASA has released 10 new images, all from the new WFC3 instrument and others, including the Cosmic Origins Spectrograph. Images include NGC 6302, Carina Nebula, Stephan's Quintet, Markarian 817, Abell 370, and a few others. Great looking stuff, the WFC3 has twice the resolution of the WF/PC2, on the CCD at least, if memory serves correctly. Eta Carina is a fascinating object, and there are at least two releases in this 'Early Release Observations' set.

Campaign to win official apology for Alan Turing
A CAMPAIGN has been launched to win a posthumous apology for computer pioneer Alan Turing over his conviction for homosexuality.
The brilliant mathematician, who spent his key years at Manchester University, is hailed as one of the founders of modern computing.
But a conviction for homosexuality effectively ended his career. Troubled Turing went on to commit suicide in 1954, aged just 41.

Lightning detected on Mars
The first detection of lightning in a Martian dust storm has likely been made by a new detector on a radio telescope.
Scientists have long thought that as with dust devils and storms here on Earth, Martian dust storms should produce lightning. But direct evidence of electric discharges on the red planet was lacking.
