Skiftesspaning: peak oil, nanorobotar, DNA-testning och datorätande myror

Lite gott och blandat från nyhetsskörden.

Peak oil? Nja. Oljeproduktionen slår nya rekord:

World Oil production figures from the Energy Information Administration (EIA) International Petroleum monthly for February 2008 reached a new high of 85.921 million barrels of oil per day. 36.881 million barrels of oil per day from OPEC in February. 74.657 million barrels of oil per day world oil production including lease condensate which is up from 74.431 millions barrels of oil per day in January, 2008.

Kur mot cancer? Nanorobotar i blodet som likt målsökande missiler söker upp cancertumörer kanske kan bli räddningen mot den fruktade sjukdomen:

That could lead to very early detection before the cancer even begins to spread, and ultimately these tiny vehicles — 3 million times smaller than an earthworm — may be able to deliver a lethal blow to the tumor.

På tal om små varelser som käkar saker: i Houston har man stora problem med myror som tar livet av datorer och andra elektroniska apparater:

Supposedly, crazy raspberry ants are fond of electronics.

Du har väl provat den senaste hälsoflugan, DNA-testning? Ta reda på vilka sjukdomar du har särskilda anlag för. Värt pengarna? Tja, priset är sjunkande så det kan vara värt att vänta något år. Då kan dessutom dagens relativt omogna tjänster ha vuxit till personaliserad medicinering.

Har du tid över i helgen kanske du kan prova spelet Foldit. Det går ut på att vika proteiner och kan hjälpa forskningen bygga nya proteiner som inte återfinns i naturen:

The game, called Foldit, is part of Baker’s vision for the future of protein engineering. His algorithms are good at the nitty-gritty of generating completely novel protein sequences for a particular purpose. But humans, who are better at seeing the big picture than computers are, could improve computer-designed proteins by playing the game.

Trevlig proteinvikar-helg!
