Earlier we proposed that solving puzzles should be a school subject. A study by researchers at the University of Exeter shows that solving puzzles like crosswords on a daily base, strongly improves one’s cognitive abilities at old age. More precise: regular puzzle solving is linked to better memory and thinking skills.
This study supports our proposed policy of including puzzle solving in the curriculum of schools, as it suggests that this will improve overall intellectual skills and hence will likely have a positive effect on academic performances.

Doctor Aimee van Wynsberghe points out that sex robots both offers possibilities and risks: on one hand this emerging technology could help certain people (elderly or disabled people) to get sexual satisfaction, but on the other hand there is the risk of increased objectification of women.

Cosmic radiation is one of the most serious dangers to human spaceflight and hence a serious issue for space colonization. Consequently radiation protection is no luxury for space settlers and without this space colonization is unlikely to succeed.
Researchers at the Australian National University have developed a new nano material that could reflect cosmic radiation. A thin film of the material could provide radiation protection of astronauts and space settlers. Compared to other shielding techniques this material appears to offer a light-weight protection.

An opt-out system means that every person is automatically an organ donor unless he/she or his/her next of kin objects. Continue reading Organ donation
