Thinking Clearly

A new study published by researchers at North Carolina State University shows a correlation between high blood pressure and decreased cognitive abilities in seniors. This could indicate that stressful situations may make it more difficult for seniors to think clearly. In the study, the researchers looked at persons with a systolic blood pressure of >130 mmHg. When their blood pressure spiked, it was accompanied by a decrease in cognitive function. The study was published in the Journal of Gerontology: Psychological Sciences.

Teddies In Space

It sounds like a bad sci-fi movie from the 80s, but it is actually a really, really cool science project. Students at the University of Cambrige recently managed to put four teddy bears in space by using a weather balloon. The maximum altitude reached was about 30km, and to prevent the bears from freezing solid the students designed and built space suits for them to wear. This was really the main part of the project, and was an excellent way of teaching the students the principles of insulation, convection, conduction, radiation, pressure and loads of other exciting physics. Oh, and the students in question were actually aged about 11-12, and I think this is a wonderful way of getting young kids excited about science. I really hope other schools follow Cambridge’s example on this one. 

I mean, how cool is that!
