  1. Satoshi Kanazawa... Not only is he the author of this PsychologyToday article, he is also on the editorial board for the journal that published this "research". The guys is a complete hack. I don't know how he has career or why evolutionary psychology is even a field....
  2. There are issues with your source. The man in the video is a geologist, he can't speak with any level of expertise on the matter of climate. Secondly, he is on the board of several resource extraction companies, including oil and gas companies1. These companies have the most to lose if policies for climate change were implemented. It is fair to say he has a conflict of interest. 1. http://www.bloomberg.com/research/stocks/people/person.asp?personId=6226016&privcapId=30719904
  3. I think the older mac computers were worth the extra cost. You got a great OS, nice hardware, and great design. The older models you can upgrade and repair yourself. The new models are getting more and more restrictive. This makes them consumer products. For example, the new mac mini has its ram soldered to the motherboard. The macbook air has an integrated battery, which is hard to replace. They are making increasing difficult for the end users to fix the failure of component or the upgrade their computer. This means that the products are being designed to be replaced with newer models in a sorter cycle. I don't plan on replacing my macbook pro anytime soon; I can still repair an upgrade several of the components in it. However, if it died, I would not replace it with another apple computer.
  4. There isn't a universally accepted definition. Some definitions work better for some organisms than others. However, a species is ultimately a taxonomic rank, and thus species are very nominal. They allow us to make sense of the world, but we can't make a universal definition that works both for bacteria, pineapple, and turtles. This doesn't undermine evolutionary theory. Evolutionary theory is about how populations become different from one another, this can be observed regardless of our arbitrary categorizations. What is difficult is when to decide when two populations are two species. For example a Chihuahua is only a subspecies of wolves (Canis lupus), not a new species merely due to how these things are defined. However no one disputes their shared ancestry.
  5. You can have double stranded RNA, and four stranded DNA (see the image below) DNA is less reactive than RNA due to it having less alcohol groups (-OH) on the sugar. The backbone of the polymer is less likely to be broken a part due to chemicals in the environment so it is a better at long term information storage. It has to do with shared biochemistry and genetic information. A carrot, bacteria, and hippopotamus have similar enzymes, chemical pathways, genetic information etc.
  6. Plus, MO theory is supported by experimental evidence. It correctly predicts that O2 is magnetic
  7. I think it probably depends on what Asian country. For example the Philippines is culturally more western than China. There are also many culturally western, ethnic Asians, living in the US and the common wealth. Treating Asian women as one homogenized group to make generalities about is fairly unproductive imo....
  8. There are people working on that... Some of the programs they use for the neuron simulations are free and you can mess around with them.
  9. It was a necropost, this goes against rule number four.

  10. A post of mine was deleted. I would like to know why: is there foul language, offensive, inaccurate information, just something you did not like?

  11. damn thats crazy!

  12. The first paper using a small, USB powered, DNA sequencer was published yesterday. Here is the technique they used: http://vimeo.com/77246565 http://arstechnica.com/science/2014/12/usb-sized-dna-sequencer-is-error-prone-but-still-useful/ http://www.nature.com/nbt/journal/vaop/ncurrent/full/nbt.3103.html This is very exciting. Technologies like this will be very useful for many fields of study, from molecular ecology to epidemiology.
  13. Body cameras are just another sign of America's need to fix institutional problems with technology. For example, 9/11 could have been stopped using intelligence from the NSA, FBI, etc. However, in the pre-9/11 era these agencies didn't communicate effectively with one another. They tried to fix the problem with technology (mass surveillance), and still missed terrorists (ie Boston Bomber, who the Russians warned the US about). Airport security is another such issue. Instead of trying to reorganize, they use technology and poorly trained individuals to do security (TSA). This is not effective. Old ladies can out smart the TSA. Body cameras are the same. The police departments need to change. They don't need cameras or military gear. They need to be trained to be better. There should be higher standards for hiring and training police. Putting cameras on police will just mean that the cameras will "break during a violent struggle" etc., when the video could be used against a police person. You can't fix rape culture, police departments, or terrorism with technology. Institutional and cultural changes have to be made.
