Scientists at Stanford University (US) have developed a battery based on aluminum instead of lithium. According to the researchers their battery is fast-charging, long-lasting and inexpensive, which are desirable properties of a battery. Continue reading Developments in battery technology
One objection, from an animal welfare perspective, against in vitro meat, is the fact that current blood serum is used to feed tissue cultures. Blood serum is a popular growth medium, because it contains the substances needed to culture cells ex vivo. Continue reading Algae and in vitro meat
A fair number of experiments on animals is done for educational purposes. For instance aspirant-surgeons practice on animals before they are allowed, or animals are dissected just to teach students what an animal looks like from the inside. Continue reading PVC Rats
A flourishing space settlement needs a functional ecosystem. And almost by definition, that means an ecosystem that can maintain itself. However, setting up a functional ecosystem is not quite easy. Continue reading Designing ecosystems
Umbilical cord blood contains stem cell, which can be used for scientific research and medical treatments, including the treatment of leukemia. Since umbilical is a waste product without a real purpose, the use of umbilical cord stem cells is much less controversial than the use of embryonic stem cells.
Robin Baker describes in his book Sex in the Future, a new method of contraception. This system consists of three components: sterilization, storage of sperm and eggs, in vitro fertilization. According to Baker this system has the following benefits. First sterilization is quite effective in preventing unwanted pregnancies. But by storing human gametes outside the body and ivf, sterilized people can have children when they desire. Continue reading The prospect of artificial sperm and eggs
On Science Daily an article of Solar cells with an efficiency over 40 percent, i.e. more than 40 percent of the sunlight received is converted into electricity. This development is important, both for space settlements and terrestrial energy supply.
According to Polish scientists radiation in space is much less hostile than had been expected. This research of great importance for future space settlements, as cosmic radiation is a major hazard for space travelers.
However, we can make a small point of critique: the research was conducted at the ISS, which well inside the Earth’s magneto-sphere. Our magnetic field protect our planet against space radiation.
On Science Daily there is an interesting article on the structure of quantum dots. Better understanding of this structure would lead to more efficient solar cells, wich of great importance for space settlements.
It has been done: the first baby has been born after a womb transplant. Swedish doctors have transplanted a womb into a 36-year-old woman who subsequently got pregnant and give birth to a son. Though being born prematurely, he is healthy. You could read more in The Guardian.
