kanzure"I am not altogether certain that ET would want to launch a fire and forget probe to virally copy himself across the cosmos. That would make ET an r-strategist and that doesn't fit the profile of intelligent organisms which are usually K-strategists. After all, if there is any chance that you might outlive your host star, why would you spawn potential competitors all over your galactic neighborhood that would make it difficult to ...05:47

kanzure"ET may or may not want to make copies of himself but we were talking about thermodynamic efficiency and the cost of building a Von Neumann probe would be trivial for an advanced civilization. It would be like one of us purchasing a candy bar. The cost of launching such a probe to the nearest star at 25,000 miles an hour, something we can do today, would cost even less. If somebody did that just once then in just 50 million years, a tiny ...08:43
kanzure... fraction of the life of the universe, the Galaxy would look vastly different from what it looks like today  and ET could harvest astronomical (and I mean that word literally) amounts of energy. Your explanation of why we don't see that engineered Galaxy is that out of the billions of individuals in millions of civilizations no one, absolutely no one, bothered to buy that candy bar."08:43
kanzure"Be honest now, does this excuse put forward to explain away the lack of large scale engineering really strike you as credible? If you knew for a fact that ET existed but had never seen the night sky is this really what you would predict the sky would look like?  I don't see an elephant in my living room so I can reasonably conclude there is not an elephant in my living room. Sometimes a absence of evidence is evidence of absence. "08:43

nmz787_i1me too11:56
nmz787_i1I've been interested in it for a decade at least11:56
genehackergive me a design problem11:56
nmz787_i1I was looking into yeast to setup a serotoning receptor reporter system11:56
nmz787_i1serotonin11:56
nmz787_i1so you could throw molecules at it and learn if they had any effect11:57
kanzuregenehacker: mimic or bind ot some of these proteins http://diyhpl.us/wiki/genetic-modifications/11:57
nmz787_i1(serotonergic effect)11:57

kanzureenzymatic conversion between blood types http://2014.igem.org/Team:Tuebingen11:58

genehackerhey I'm not trying to make those sorts of 'drugs'12:14
kanzureperhaps not, but it's a good toy problem12:15
Douhetgenehacker, can you make a drug that makes a tree grow faster?12:16

genehackerand by sure I mean maybe12:16
kanzurehow about an antimicrobial12:17
kanzurelike some of these http://en.wikipedia.org/wiki/Antibiotics#Status_of_new_antibiotics_development12:17
Douhethmmm12:21
Douhetgenehacker, exactly what information/detail is in said pharmocophore12:21
Douhetelevated cytokinin levels would increase three growth but pharmocophore would describe... either molecules that sense cytokinin levels or produce them?12:24

kanzure.wik pharmacophore12:25
yoleaux"A pharmacophore is an abstract description of molecular features which are necessary for molecular recognition of a ligand by a biological macromolecule. The IUPAC defines a pharmacophore to be "an ensemble of steric and electronic features that is necessary to ensure the optimal supramolecular interactions with a specific biological  …" — http://en.wikipedia.org/wiki/Pharmacophore12:25
genehackerdrug design is like making a key, you are trying to find a molecule that fits into another molecule12:25
genehackera pharmocophore is like a description of what shape the key should be12:26
kanzureantimicrobials seems like a good option then12:26
kanzurereceptors tell you the shape (roughly)12:26
tastybudsOr a microbe booster12:26
tastybudsHi12:27
genehackerroughly is typically not enough from what I here12:27
kanzuregenehacker: what's the best result that is similar to what you want, that people previously figured out12:29
genehackerI think I'll do some HIV receptor or something12:29
ryankarasonquantifying the relationships between fungi and plants might be a good start for "make[ing] a drug that makes a tree grow faster"12:31
ryankarasonanyone here done any work on making "myco-composites" ?12:32
nmz787_i1i've read up on them12:33
nmz787_i1there were some guys from RPI doing than when I started at RIT12:34
ryankarasoni find it /really/ hard to find papers on them. so i plan to start doing expirements myself and start documenting.12:36
nmz787_i1there's also the book 'mycelium running' which is probably the closest thing to a bible on neat myco stuff12:37
Douhethm, so to answer genehacker's requirement I need to find descriptions of histidine kinases CRE1/AHK4, AHK2, and AHK3. Out of my league12:40

kanzure"But instead of spawning killer ants or a 50-foot giantess, the researchers have found a controlled way to cause a tissue sample swell to roughly four and a half times its size -- enough to make features of brain cells or cancer cells discernible under conventional microscopes."18:13
kanzure"“One of our lab’s strategies is to do the opposite of what everyone else seems to be doing,” said MIT neuroscientist Edward Boyden. “One of the ideas we were kicking around was if you make a sample big enough, could you take a picture of viruses or something else really small with your cell phone? We’re nowhere near that, but it’s the kind of thinking we’re exploring now.”"18:14

yoleauxExpansion microscopy18:14
kanzure"The new technique, called “expansion microscopy” can’t yet reach the level of fine-scale resolution of electron microscopes or the super-resolution microscopes that won the Nobel last year. But it may offer an inexpensive way for people to examine fine cellular structures at a detailed level using off-the-shelf ingredients.18:14
kanzure"Researchers first attach glowing tags to the particular molecules they are interested in seeing -- for example, they might choose receptors found on the surface of a particular kind of cell. Next, they add the building blocks of a polymer that is more commonly found in baby diapers, used to absorb moisture. A substance that Boyden compares to meat tenderizer is used to strip away molecules that could constrain the tissue from expanding. ...18:15
kanzure... Last, they add water, which is absorbed by the polymer and swells up. The swollen tissues can then be examined under microscopes commonly found in research facilities. In the paper, the researchers meticulously checked to make sure that the expansion occurred evenly in each direction and found that it did -- within 1 percent to 4 percent."18:15
kanzure"His team will publish a website explaining exactly how to perform the technique, in the hope that it will be widely adopted by scientists. The team is also applying for a patent on the technology, in case it can be further developed for medical applications."18:15
kanzure"Two years ago Karl Deisseroth, a neuroscientist at Stanford University who was Boyden’s postdoctoral adviser, developed a powerful technique called CLARITY that turns brains transparent using a similar process. Deisseroth said in an e-mail that the researchers had noted then that the process enlarged the brain tissue moderately, which was a problem they needed to correct. They added an additional step to shrink it back to normal size."18:15

kanzure"I think the main point of conflict over the debate in this thread arises from people considering two different phenomenon. John Clark is making the important point that the giant lack of obvious large-scale engineering is STRONG EVIDENCE in favor of there being no civilizations in our galaxy that have the capacity for large-scale engineering. In the last few emails I have counted >10 nice, creative alternative hypotheses for why we ...18:44
kanzure... don't see some specific type of this evidence, and these are very helpful to clarify where the null hypothesis might be wrong. However, it's important to make this distinction, that where our priors strongly suggest that large-scale engineering would be visible as large-scale engineering, alternative hypotheses need to be extraordinarily powerful and explanatory to beat out the null hypothesis. I am glad we are generating all these ...18:44
kanzure... other thoughts, but it should be noted that the obvious leader is that there exist no such civilizations. It may help our cumulative understanding to keep this in mind, consider all the evidence that there is no such civilization, and if someone has a hypothesis that they think is strong enough to be in the top 2 or 3 (of course others are helpful to mention to, but with the caveat that they're improbable), they note the predictive ...18:44

We obtained surface temperatures of approximately −50C with a simple cooling technique: discharging inverted cans of “canned air” duster spray directly onto the chips. At these temperatures, we typically found that fewer than 1% of bits decayed even after 10 minutes without power.
