Loneliness in people over 50 years old seems to be linked to as much as a 30 mmHg increase in systolic blood pressure
, pushing many over the 150 mmHg mark that defines hypertension. How this happens is unclear, but figuring it out could lead to major improvements in our understanding of social/psychological effects on the body. Without even knowing how it works, knowing that
it happens is a great place to start some public health interventions: get seniors out of the house, into social situations. (great idea, but doing it will be a challenge)
Researchers have successfully powered a helicopter jet engine with a largely coal-based fuel
. While this in and of itself is cool, the claim is that this will help us be independent of foreign oil is preposterous. Coal is at least as limited a resource as oil, and the US certainly has no monopoly on its production. Still, an interesting concept.
