Katniss_EverdeenI regret to inform you
that this is bullshit.
Zimmermanturning light to matter,
MiomoRegarding the "artificial photosynthesis":
This is easily a bad thing more than good. If anything, it provides another argument for cutting down forest. If we can create artificial photosynthesis, then the only reason for keeping forests are to support the ecosystem, and those two points together aren't really keeping the forest from being destroyed.
Perhaps the only good thing is the ability to carry out other reactions. If we need a medicine made, throw it out in the sun and voila. It cuts out the need to transmit electricity for the purposes of molecular engineering. Also, if there's an artificial surface that really can't be made "green". A roof with moss or plants on it, photosynthesizing naturally would be much more ideal than a black one with artificial, possibly poisonous enzymes.
In the short term, for greenhouse-gas removal, it may be good, but in the long term, stabilization of the ecosystems would be much, much more beneficial.

butterslut.i don't regret to inform you that you're a dumbass
MilaKunisYou suck
.undetectedHopefully we discover a black hole that is bigger than OP's butthole. That would be nice.
las.
theBearJewThat suspended animation shit is nuts. Still don't really understand what they are doing..
Peter.the surgeons attempting to slow down the body one is sick. they are trialing it out at a hospital in pittsburgh on patients that are pretty much going to die because they dont have enough time to do the surgery. with this new method, they can slow down the body for like 2 hours, giving the surgeons time to save the patient. so sick
royalcanterlot.
Zimmermaniflscience is a cool site
LE.SkiingScientists Successfully Destroy Cancer With Nanobubbles

las.That is awesome, and very encouraging. Search and destroy, instead of poisoning the whole body. Seems like a proper step in the right direction, finally, which is quite resfreshing
VinnieFI don't know why but all these titles annoy me so much. No doubt cause they're all blown way out of proportion.
For example "scientists regrow adult tooth using lasers"
No, they did no such thing. They managed to cause stem cells in rats to form dentin using lasers. It's still a huge breakthrough, but is nowhere close to how laymen sensationalize it to be.

las.Here's the Harvard press release on it: http://wyss.harvard.edu/viewpressrelease/155/
This gives a very in-depth summary too: http://stm.sciencemag.org/content/6/238/238ra69
The headlines are sensational, like I've said, but you're sort of wrong. They've tested this on mammal and human cells, with remarkably promising results on both. Additionally, whilst this method won't and can't apply to the other essential components of the tooth (enamel, pulp, cementum etc.), dentin is the structural bulk of the tooth, and the ability to differentiate stemcells into dentin itself by stimulation is a huge step forward in tooth repair and maintenance.
Another important thing to consider that you're not acknowledging or understanding is how broad the possible implications of something like this could be, mainly in it's potential use on other forms of tissue, which is equally as exciting.
By the looks of it, too, human trials should be taking place within the next couple of years.
I can give you (from my understanding of it) a more comprehensive explanation of the process, if you'd like?
Obviously these headlines should be taken with a grain of salt, but don't prematurely accuse them of lacking substance if you don't have an actual understanding of what they're talking about.
VinnieFRight, they tested it with promising results. They haven't actually "regrown adult teeth from stem cells" as it says. Unless you think artificially growing muscle tissue, for example, is the same as regrowing a body.
But please, I don't understand what they're talking about so give me a more comprehensive explanation.
And I would argue that headline is factually incorrect. If someone managed to grow cellulose artificially (maybe they can), and the article title was "trees grown artificially in lab" then that would be factually incorrect. Just like saying you've grown teeth when really you've grown dentin is factually incorrect.
But still, it's cool stuff. They headlines do definitely blow it a bit out of proportion. I'm sure if I looked into the others this would be true for 1/2 of them at least.
las.Again, dentin is essentially the mass of the tooth, giving support and structure to the other major components. The same cannot be practically said for some microscopic sugar molecule in and with trees, or, I can imagine, anything else it is a part of.
