A cool new scale...

Posted by Frenya Wed, 14 Nov 2007 15:52:00 GMT

I listened yesterday night to some podcasts from the “Naked Scientist” - probably my favorite science podcast - and heard a really cool news. Researchers from MIT created the smallest scale able to measure the weight of a bacterium. According to what Pr Scott Manalis said, they are able to segregate bacteria in a small U tube allowing to have only one at the time. He gave the example of E.coli that weighs about 100 fg (femtograms) or 1e-13 grams. One of their goal is eventually to be able to distinguish cells like cancer cells from regular, happy cells - of course using other methods in addition to the scale-. Even if this project does not go where the researchers want it to go, I think it is still a pretty cool idea and piece of technology that they were able to develop.

J’ai écouté quelques podcasts du Scientifique Nu (“Naked Scientist”) hier soir - ce podcast est probablement mon favori pour avoir des nouvelles scientifiques- et ils ont présenté une nouvelle technologie. Des chercheurs du MIT on créé la plus petite balance capable de peser une bactérie. D’après ce que Pr Scott Manalis a dit, ils sont capables de ségréger des bactéries dans un petit tube en U qui permet de n’avoir qu’une bactérie à la fois. Il a donné l’exemple de la bactérie E.coli qui pèse apparemment 100 fg (femtograms) ou 1e-13 grams. Une de leur buts est d’éventuellement être capable de distinguer les cellules cancéreuses des cellules saines - bien sûr en utilisant d’autres méthodes en complément de la balance -. Même si ce projet n’aboutit pas là où les chercheurs veulent, je pense que c’est quand même une bonne idée et une technologie des plus intéressantes.

    That could be acceptable to remain suspect of any over-all sector caused by a small amount of harmful apples? You can get at a minimum a few very important variation, seems for me. To start with, not everybody queries which will discipline really works, any incorrect and even less-than-honest allege can once in a while end up marketed. Though regardless if you can get any specific “miraculous” alternatives as a result of faith-healing, outside your body’s possess ability to overcome once more, is amazingly a good deal within situation. The second thing, that expose’ in theft and even oversight on discipline is produced very nearly especially as a result of discipline. Nevertheless visibility in theft and even oversight on faith-healing is virtually hardly ever achieved as a result of several other faith-healers.
