I think that this was a great article because of all the interesting things they talked about. I thought it was interesting that there are even bacteria that can grow in space! I is also amazing that they are shaped as column-and-canopy. When Collins says the quote, "The unique appearance and structure of the P. aeruginosa biofilms formed in microgravity suggests that nature is capable of adapting to nonterrestrial environments in ways that deserve further studies, including studies exploring long-term growth and adaptation to a low-gravity environment", I agree with Collins. Nature can make anything, from creature living without oxegen to creature living with oxegen. If we figure out how this works, then this can help us with how diease is spreading in hospitals. This would be a great discovery because we could save many lives. I would rate this article an 8 of 10 because they could have explained more about the shapes of the bacteria and what the bacteria did.
One of the first organisms on earth was bacteria, so if bacteria thrives in space and certain bacteria produces oxygen than planets without an atmosphere like mars could develop very small atmospheres. Anaerobic and facultative anaerobic could survive on Mars, so it is possible that there could be life on mars eventually. If certain bacteria thrives in weightlessness, astronauts can get very sick in space. That may be a problem as bacteria develops resistance to antibiotics.
This was a great article. I think that it is quite interesting that bacteria grow in strange ways in space this could be the next antibiotic way of doing things. If you could genetically modify the space bacteria it might be able to cure other diseases that can not be cured with antibiotics on earth.
I think this is pretty interesting. I never knew that bacteria could grow out in space! The role they play in gravity and development clearly remains unknown, but it is definite to be found out. I guess just like bacteria here, most are helpful, but some cause atrocious diseases. I find it a teeny bit strange though how they are cultured in artificial urine. I wonder though if these bacteria perhaps come in a whole new shape, or can cause a deadly illness that perhaps we have not experienced. Personally I think that they must be different in one way or another. I rate this article an 8 out of 10, it was interesting but not very informative.
I think this article was very eye-opening. If bacteria grows better in space, it could be a health hazard to anyone in it, but it could also be a beneficial to us here on earth to study more objects in space. I think that there are still tons of stuff we need to discover and look at to find out different things. With private companies now controlling all the different shuttles that go up into space, another study would have to be a more private study if they would like to conduct a similar one in the future. I think that this article should get a 5/10, because the content was interesting, but the article was long and somewhat confusing.
I loved the possibilities that this bacteria growth could have on medical researches. If this bacteria can be used in medicines, or trips into space it would prove to be very beneficial for our community. Once I read the article an idea popped into my mind, that maybe this bacteria could play a major role in our studies of the article published last week about spouts of water on Europa. If this bacteria is having reaction different from on Earth in space, than I believe that it could be very possible that trying to find out how the bacteria reacts in the underwater sea of Europa could lead to new discoveries for the two scientific findings.
If bacteria could grow in space, that means that there might be alien life out there. However if astronouts were to go into space and got sick with all this antibiotic-risistance going on that would be a big big problem. It is also really cool how they have a new shape.
I think this was a great article. However, I don't think this is a big suprise to discover that bacteria grow differently in space. After all, humans do too. On the other hand, bacteria can survive much more extreme temperatures than we can, so it is still a remarkable discovery. I have a few questions, though. Is it possible that such change could only be for that specific type of bacteria? Are the scientists doing more to prove their theory? I think that it is cool to discover that bacteria adapt to their surroundings, just like we do. I was also a little confused when they said a column and canopy structure, but when I researched, I found that there are mushroom shaped, flat, and column and canopy biofilms. I think that this is something definitely worth investigating because it could be possibly dangerous to humans in space. In this situation, I would send vials of different types of bacteria to test them all, especially the most common types. I think that scientists should delve deeper into this study, and hopefully we will determine whether biofilms are safe in space or not.
It is a strange discovery that bacteria grows differently in space, but it may not really be a surprise. What would be great, though, is if we could genetically modify them to become antibiotics. Also, this study proves their may be alien life out on other planets. If so, the astronauts may get badly sick in space. I found it interesting however that the bacteria grew in a different form. I don't understand why the bacteria was cultured in fake urine, however. Is it because they cannot survive outside of the urine? The scientists should look into the study more to find out if there are any antibiotics or deadly diseases that this new form of bacteria may generate. Also, perhaps, if they were only using a specific type of bacteria some other types of bacteria may not be affected in space.
If bacteria change in space, they might genetically mutate over time. This could create a new bacteria species that might be able to only survive in space. I wonder if they might do experiments to see if bacteria evolve differently in space as well. Other species of bacteria might grow in space differently than other bacteria grow in space. Viruses might also grow strangely in space. This could lead them to try the same experiment with invertebrates, and ultimately vertebrates.
I really enjoyed this article. I think that it is cool that bacteria grow differently in space then on Earth. I wonder if bacteria grow differently on different planets. I definitely would like to learn more about the growing of bacteria. I was also wondering if there was a reason that they chose Atlantis to grow the bacteria. I would give this article a 9.
I found this article interesting. Bacteria are not archea, but still, they can survive much more extreme environments than us, even some can survive without oxygen (and prefer that). Pseudomonas aeruginosa is a facultative anaerobic type of bacteria, which means that it doesn't need oxygen to survive, but prefers it. I think that is part of the reason why this bacteria doesn't need oxygen to survive. I would like this article to explain more exactly what the column and canopy structure is besides the picture, I don't really understand what it is. I'm guessing it is a sort of cocci shape, though a little different. Lastly, I was wondering, why shouldn't most anaerobic bacteria be able to grow in space since they don't need oxygen?
It's unsurprising that bacteria, too, does and can produce in space. Not to offend any individual, but I don't see the reason of astonishment. Anyways, Collins does focus on how the prospering bacteria in space can bring positive change into even our local communities. Although (and even making this remark, I doubt it), I believe there is a chance that we can definitely transport disease and virus-ridden bacteria into astronautical environments, so if we want to continue doing such in space, we must proceed with caution.
I have not even thought of bacteria in space! I already knew that bacteria could live in extreme conditions but it is even more surprising that they can live in SUCH extreme conditions. I agree with Erica when she said nature can make anything from creatures living without oxygen to creatures living with oxygen.
