Link Making weedy rice more competitive could exacerbate the problems it causes for farmers around the world whose plots are invaded by the pest, Lu says. Certainly, no environmental groups were warning against just such an occurrence. Asshats.

I get all subconscious that they can hear what i'm saying and fnord12 shushes me when we have the windows open and argh. Research in Auckland, New Zealand - the largest urban area in the country and a city built for the age of the motor car - shows that solar panels fitted to the average suburban home can produce enough power for that household, extra to charge an electric vehicle, and still generate enough watts to export a surplus to the grid. I hate being shushed. *pout* By min | August 13, 2013, 11:26 AM | Science | Link The obesity epidemic is reaching animals, too. Cats and dogs. Sewer rats. And even control mice used in experiments. As the study says (click through the link above for the PDF): The paper goes on: Increased body weights among laboratory animals have implications for the outcomes and design of the experiments that use these animals. Among several laboratory animals, it is known that calorically restricted individuals live longer and obese animals have shorter lifespans. This has had implications for toxicology studies in which some researchers have shifted to controlling for reduced lifespan and increased body weight. As the post i linked to says, caveats apply, but it's certainly interesting and maybe a little scary. By fnord12 | August 9, 2013, 6:38 PM | Science | Link Kevin Drum says, "it's August, and every blogger in the country is having a hard time finding anything to write about. So the Pew survey is getting lots of attention." But this survey is about extending life extension, and living forever is a life goal of mine, so this is more than just summer filler for me (if i have nothing to blog about i should be writing Team America reviews). Drum observes that the majority of correspondents say that the ideal life span is the current standard lifespan, and he doesn't believe them. Now, on the one hand, i don't want to scare scientists into thinking "Hey, we're working on this immortality stuff and the people don't even want it!". But on the other hand, every time the subject of life extension comes up, people start worrying about overpopulation. So if most people want to decline the life extension technology, that's fine with me. By fnord12 | August 7, 2013, 4:31 PM | Science | Link So i guess this is becoming more and more of a reality. They're doing it for all the same reasons i'm vegan; as the article says, "Breeding animals destined for the dinner table takes up about 70 percent of all agricultural land", and with that comes additional use of oil and water, major pollution (animal waste and fertilizer), etc.. Finding other sources of protein is a great way to reduce all that resource use. I'm curious if this would be accepted any more than, say, soy burgers are, though. Anyone who's been vegan for the past 15 years or so (all six of us) knows that vegan burgers have come a long way. From burgers that tasted like dry newspapers to burgers that tasted like mushy newspapers to Boca patties and now Gardein, which as far as i'm concerned is amazing. So my first reaction to someone devoting all this R&D to growing burgers in a lab is "Why bother?". But i can also admit that being away from real meat for 15 years has moved the goal posts for me and someone going directly from real meat to Gardein is not likely to be as impressed. One advantage these guys have is they recognize that you have to have some fat in the product. "Taste is the least (important) problem since this could be controlled by letting some of the stem cells develop into fat cells". One big problem with a lot of vegan products (not Gardein so much) is that they're also serving people who think that all fat is bad, and they're also afraid of salt, so you get these dry tasteless products. Again, it's gotten a lot better. But since hippies won't be the primary target market, the lab meat people can skip all of that. But the question remains: will people eat this? I'm fairly certain i wouldn't, despite it really addressing all the problems i have with eating meat. The gross-out factor seems too high to me, but again, with 15 years away from meat there's an additional gross-out factor for me than there would be for a current meat eater. I did think this was a hilarious juxtaposition, though: The other possibility is that when this starts becoming mass produce-able (they're still a ways away from that) it could just start showing up in stores without any indication that it's different from other meat. That's already true of genetically modified vegetables so i don't think it's unlikely that the same might become true of lab produced meat. By fnord12 | August 5, 2013, 9:06 AM | Science | Link Are you familiar with the prisoner dilemma scenario? You and another person are "suspects" who are separated and each must choose to either inform on the other suspect or keep your mouth shut. The consequences of your decision are as follows: You have no way of knowing what the other guy's going to do. What do you decide? From watching episodes of Law & Order, i know that the best thing for all parties is to keep your damn pie hole shut, despite the seemingly good return on being the first to spill the beans. And it seems like our genes feel the same way. Evolution does not favour selfish people, according to new research. Now, here's where the possible programming to make us more likely to cooperate comes in. [R]esearchers, who looked at a large sample of people over a month-long period, found that happiness is associated with selfish "taking" behavior and that having a sense of meaning in life is associated with selfless "giving" behavior. According to the first article, cooperating ensured our genes surviving. Did our genes basically make it more likely that we'd choose to cooperate and help others by making us feel physically better if we did? And poorly if we chose to be selfish, triggering a response in our bodies as if we were "enduring chronic adversity", as noted in the second article? Looking at our modern society, i believe the threat of heart disease, cancer, and depression is no longer an effective deterrent to being selfish, not in the face of immediate, euphoric gratification. When I look up, I see people cashing in. I don't see heaven or saints or angels. I see people cashing in on every decent impulse and every human tragedy...They think that they're smart, and that the rest of us are dumb.

Link Ofc, further down the article, the conclusions made by this study are contradicted. But still, you should watch out for trails of glitter mysteriously leading to your closet. Might be aliens.
