On ScienceDaily we found an interesting study:
All plastic waste could become new, high-quality plastic through advanced steam cracking Continue reading Plastic recylcing

Artificial wombs progress
The Guardian reports that Dutch researchers have been awarded a €2.9 million grant to develop a prototype artificial uterus. Though artificial uteri have several benefits, they also raise a multitude of ethical questions.
Organ cultivation
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
Future Fuel
Not directly related to space settlement, but still interesting to think about.
The age of (cheap) oil is doomed in the long run, even if we do not care about climate change, as petroleum is a finite resource which would eventually be depleted. However, our modern industrialized society requires a lot of energy and without it our planet cannot sustain a ten billion population.

Electric vehicles and public health
Our regular reader will know that we are quite hawkish when it comes to air quality and public health. One of the measure we have proposed is for space habitats to ban the use of internal combustion engines. A study by researchers from Cornell University provides a solid scientific base for a complete ban on internal combustion engines. Continue reading Electric vehicles and public health
Polymer waste and recycling
Plastic waste is a major environmental and social problem. The fact that plastics or polymers hardly decompose naturally is one of the contributing factors to the issue of this type of waste. Though polymers could be recycled only a tiny portion of separately collected plastic waste is actually recycled. Continue reading Polymer waste and recycling
Energy storage
When it comes to the world’s future energy supply both fusion power and renewable energy are experiencing a steady pace of progress. However, regardless of the particular choice of technology, there is an ever increasing need for a reliable method of storing energy. Continue reading Energy storage
Organs on demand
Researchers at Tel Aviv university have managed to print a fully functional human heart. Though currently the size of a rabbit’s heart, 3D printing of (human) organs seems to be feasible in the near future. Continue reading Organs on demand
Artificial wombs progress
Science Daily reports yet another breakthrough in the development of artificial wombs. Researchers are now able to keep extremely premature lamb fetuses alive in an artificial uterus. If this development continues, it will be possible in the foreseeable future that the entire gestation could happen outside the body. Continue reading Artificial wombs progress
3D printing en masse
On ZDNET an interesting article about Markforged – a company that is working on a mass production 3D printer. As we have previously pointed out on this site, 3D printing is along side with in situ resource utilization one of the key technologies that will be of critical importance of making space settlements independent from terrestrial imports.
