Quote They estimate that the eruption delivered 146 teragrams of water to the stratosphere. One teragram is the equivalent of a trillion grams, and in this case, it was equal to 10% of the water already present in the stratosphere.

JoeSchmuckatelli Posted August 26, 2022 Author Share Posted August 26, 2022 (edited) Not sure if this is science - or just someone having fun with technology in the sciences... Basically, here are a bunch of photos of parts of our galaxy and other astronomical phenomena where the image is translated into music (well sound). Note: not set to music... The image data is converted to sound. ...except that they also try to make the images even more musical, which feels 'artistic'. I find all this both compelling... And a little odd...

JoeSchmuckatelli Posted August 26, 2022 Author Share Posted August 26, 2022 (edited) Not to be outdone: Doppelganger epigenetics explains differences in unrelated people who share genes. https://www.cnn.com/2022/08/25/health/doppelganger-dna-study-wellness/index.html These women are not related Neither are these men "... scientists think they can explain what it is that makes them look so similar -- and could explain why each of us may have doppelgänger. People who resemble each other, but are not directly related, still seem to have genetic similarities, according to a new study. Among those who had these genetic similarities, many also had similar weights, similar lifestyle factors, and similar behavioral traits like smoking and education levels. That could mean that genetic variation is related to physical appearance and also, potentially may influence some habits and behavior."

JoeSchmuckatelli Posted August 30, 2022 Author Share Posted August 30, 2022 In a boon to those of us who enjoy reading science articles: Quote critics of paywalls argue that they obstruct the free flow of information, have enabled price gouging by some publishers, and force U.S. taxpayers to “pay twice”—once to fund the research and again to see the results. Since the late 1990s, the critics have lobbied Congress and the White House to require free and immediate “open access” to government-funded research. ... The new policy reflects the profound changes that have rocked academic publishing since the U.S. public access debate began in earnest more than 25 years ago. Then, subscription-based print journals were the primary means of disseminating research results, and publishers fiercely resisted any policy change that threatened an often highly profitable business model. But pressure from university libraries tired of paying rising subscription fees, and patient groups angry about having to pay to read taxpayer-funded biomedical studies, helped catalyze serious discussion of policy change. At the same time, the rise of the internet fueled publishing experiments, such as open-access journals and the posting of freely accessible “preprints” that have not been peer reviewed.

Life in cold and dark climates seems to cause lifeforms to produce significant quantities of ethanol in general. There's a joke out in the countryside here that if you want to buy moonshine, look for the house of the local priest. That'd be the only place you wouldn't be able to buy moonshine.

Man yeast convert sugar into ethanol and get energy from it, its best done without or at least limited access to air because then the more efficient bacteria who simply convert sugar and oxygen into co2 takes over. Stone age biotech. However using ethanol as an antifreeze in an animal. You get an animal who is dead drunk all the time, dead as in enough alcohol in the blood to prevent freezing just an degree will kill you. Still ethanol has an low toxicity because you can drink it so its probably easy to evolve to have lots of it. Quote Link to comment Share on other sites More sharing options...

I remember reading about anthropological evidence that Neanderthals had been laid in the backs of caves under deep beds of collected wildflowers. Whether this constitutes “deliberate burial” in the field I couldn’t say.
