The benefits of daily puzzles

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.

Radiation protection

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.
