How can we bring down the costs of large space telescopes? New research says they could be radically cheaper if their mission goals could be reconfigured to use off-the-shelf components.
  • I don't know how much of a factor the cost of the components themselves were in the ballooning costs of the JWST, but if COTS could represent a major savings in cost without compromising the performance of the spacecraft and risking catastrophic equipment failure in the harsh environment of deep space, I'm all for it.

  • North Korea celebrated its founding with a military parade featuring dump trucks modified to work as rocket launchers
  • Probably wouldnt be too hard, with North Korea being as poor and hard hit with sanctions as it is, there are few motor vehicles in the country, and in a war time scenario they would likely be using almost every single one (except for the personal vehicles owned by party elites) in a military capacity.

  • Some GameBoy Advance Fun
  • You know now that I think about it, I wonder how many M-rated games were released on the Game Boy/DS systems. I know some of the obvious ones would be id Software ports (like the Wolfenstein 3D seen in the picture) and the GTA games (both the GBA one from the mid 00s and Chinatown Wars from later), but other than those I can't imagine the list is a very large one, especially considering most of the people who would have been playing on those systems at the time would have been kids and teens.

    Edit: after a quick google search, it looks like there were a grand total of 9 M-rated GBA games released, most of them being not very good ports of more popular console/PC games (though an exception apparetly goes to Max Payne, which managed to successfully convert the original third person shooter into an isometric game). Similarly, only 11 M-rated games were released on the DS, the best and most well known of them being Chinatown Wars.

  • Vision 2030 is Saudi Arabia's grand plan to future-proof its oil-based economy. Experts say it's a huge risk.
  • I'm not confident that huge flashy megaprojects and big foreign investments are really doing much to prepare Saudi Arabia for a post-oil future. But at least Saudi Arabia hasn't alienated itself from its most crucial customers and engaging in a real-time act of self-destruction.

  • NASA exploring potential for supersonic passenger jet which could fly from London to New York in 90 minutes
  • If sonic booms could be reduced to a quieter level, I wonder how it would affect the design and operation of future military aircraft, whether they would feel like they were more free to fly at supersonic speeds over populated areas and whether they would fly supersonic more frequently (this could be doubtful because it would use up more fuel and create more wear on aircraft components, driving up fuel and maintenance costs).

  • OP ED: China’s Fast and Cheap Nuclear Gives Its Climate Ambitions a Boost
  • I'll preface this by saying I don't really know anything about the Chinese Nuclear Energy Industry so I can't really give an informed opinion on the matter, but if I had to guess what makes Chinese nuclear reactors cheaper and faster to build, my guess would be that Chinese Government regulations surrounding nuclear reactor construction are looser than those in the West (and it makes sense on some level, China is a fast-growing nation and Party officials are probably more concerned about getting power plants built to meet rising demand than they are about potential disasters that may result), meaning that Nuclear Reactor designs in China can be simpler, lacking many of the same safety devices and controls that are mandated on Western nuclear reactors, and as a result are cheaper and faster to build, just like how Soviet nuclear reactors were cheaper and simpler than their Western counterparts as a result of lacking many of the features designed to make reactor operation safer and reduce the risk of a catastrophic failure.

    The problem is it only takes one Chernobyl-scale catastrophe (and sometimes not even that) to bring the entire industry to a screeching halt and permanently damage the public's trust in the industry and confidence that it is indeed a safe source of energy to be pursued further.

  • So this is Star Trek, huh?
  • I mean this is pretty true of any Star Trek series. DS9 from the 90s probably has the widest gulf between grim and goofy episodes; in one episode there's a war criminal who gloats about committing genocide and getting away with it, and another episode from the same season has the cast playing hopscotch.

  • Declining cost of renewables and climate change curb the need for African hydropower expansion
  • One of the most encouraging stories of the last 15 years has been the dramatic fall in cost of renewable energy and its emergence as a real competitor to existing non-renewable energy sources.

    Wind and Solar power are obviously not without their own problems, the largest is that they are intermittent power sources and there is a need to store the energy for days which are cloudy or windless; there is ongoing research in improving battery storage technology for grid-level use and creating carbon-neutral fuels that can be made using renewable energy to meet this need.

    But the fact that solar and wind power are so cheap and easily scalable, especially compared to other methods of generating power, is a positive development in the ongoing effort to de-carbonize the energy sector worldwide, although there is still a long way to go before we as a species are truly finished with our dependency on non-renewable energy.

  • We are so far away from everything
  • I kind of wish there was more emphasis on making the best out of what is currently possible instead of waiting around for scientific and technological breakthroughs that will take an indeterminably long period to come to fruition, if they do at all.

    I guess I'm so used to hearing about distant solutions to present-day problems and I never hear much about how these problems could be addressed today (although in some cases, like with climate change, this inevitably involves things like lifestyle changes and societal restructuring, which themselves can seem equally like hopium).
