NASA has discovered a new life form that can grow by substituting arsenic for phosphorus. This microbe, called GFAJ-1, was found on the bottom of Mono Lake in California. Why is phosphorous an important component of all living organisms?

What do you think about this exciting discovery?
This seems very interesting!

It reminds me of the ET movie... Really creepy...

I didn't quite understand this whole new discovery thing. How can arsenic help make cells and life thrive when its poisonous???

I thought it was really interesting that there is an organism that doesn't need phosphorous to live. I wonder if we will find other organisms like this?
ReplyDeleteis this our next unit? if so im excited!

Wow... That's so cool! That really changes the way we think about life. It' really weird that some bacteria can live off of arsenic instead of phosphorous. That must mean that we were wrong when we thought that phosphorous was necessary for all living organisms.

wow! that's really cool! how did they find it?

Phosphorus is very important because its part of dna rna and atp Dusty R. 7A
ReplyDeletealso phosphorus is part of phospholipids which make up all cell membranes

This is super important because most of the time arsenic disrupts plants and the only thing plants do with arsenic is breath it but this time the pants are making cell parts out of it and this is a amazing discovery Dusty R. 7A

When are the study notes going on eboard

How did they find that? Thats so cool!

This was really interesting. Everything we need to survive, like ATP has phosphorous and these bacteria use a poisonous chemical instead. Thats really cool. The video was helpful but the first half of it was spent on the title screen.

The article was really cool. i also looked at the bottom (just out of curiousity) and found a viedo (it was not related) but it showed lots of specimens up close, it had no sound but it was fun to look at.
ReplyDeleteThis is so cool! I always knew there was something out there....

HAPPY HOLIDAYS!! For the labeling on the energy transport chart, what should we label?

Thats so cool. It really makes you think.

I've heard of this, and my brother was talking about some reason why it didn't make sense... I forget exactly...
