We have noticed that orbital space settlements are a rather unfamiliar concept for many people. In particular people find it hard to understand the meaning of land withing the context of a free space habitat. In this piece we will try to explain some of the essentials of orbital space settlements. Continue reading Space habitats and land
We have earlier discussed the negative effects of environmental lead exposure on pre- and post-natal neural development. A new study from Canada, reported by Interesting Engineering, suggests that also fluoride might have a negative effect on one’s IQ. And this is a serious issue. Continue reading Fluoride and IQ
Today it has been 28 years ago that Linus Torvalds published the first version of the Linux kernel. This was the beginning of a IT revolution and is a milestone in the development of free and open source software. So we wish everyone a happy Linux day!
We are, to put it mildly, no fans of the colonization of Mars and instead we favor orbital space settlements. In the video below Simon Whistler of the TopTenz YouTube channel gives a nice summary of the challenges people will face on Mars.
It is not to say that orbital space habitats will be easy to build but given the particular difficulties Martian settlers will face, it will be the better alternative.
Of related interest: Interesting Engineering has an in depth article on the challenges of building human settlements on Mars.
Dementia is obviously bad for those who suffer from this condition, but it also puts a strain on society. First of all, it removes potentially active people from society and secondly other people have to take care of dementia patients. Continue reading Fending off dementia
Last week Japan announced it would allow experiments to grow human organs in animals. These experiments are controversial, not in the least place because of animal welfare concerns and the possibility of cross-species diseases. However, xenotransplantation is not the only line of research pursued to solve the shortage of donor organs. Continue reading Organ cultivation
Once again we list some interesting science news items, we believe are relevant for future orbital space settlements. Continue reading Science round up 3
All school teachers have to deal with unruly students from time to time. It is generally accepted that unwanted behavior should incur some kind of sanctions but opinions differ on what type of punishment is really effective. Earlier we proposed that schools should reward good behaviour. Continue reading School discipline
ScienceDaily reports an interesting study: Preschool teachers ask children too many simple questions. The bottom line is that most questions teachers at kindergarten ask to their pupils are way too simple (i.e. eighty-five percent of the children were able to answer them).
