Trees’ apparently significant contribution to radon ion concentrations in the atmosphere 0

From research in Australia From the abstract: Using our measurements and the published literature, we present evidence to show that cluster ion concentrations in forest areas are consistently higher than outside. Owing to the low range of alpha particles, radon present deep in the ground cannot directly contribute to the measured cluster ion concentrations. We [...]

Using a firearm allegedly does not keep one safer from brown bear attacks — but the study’s press-released conclusion appears not to have been properly broken down into its evidentiary components 0

Distorting science in the name of public policy? It seems that whenever and wherever guns are involved someone on either side of the “to tote, or not to tote” issue has to take his or her point beyond its evidence-based merit. Here is another such instance. It is based on a study of 269 instances [...]

Research in rats indicates that traumatic brain injury appears to predispose the brain to heightened fear responses, under conditions of subsequently applied emotional stress — In other words, it may be that the pool of potential PTSD (post-traumatic stress disorder) patients is significantly wider and deeper than we had thought 0

Causative pathway demonstrated in rats From UCLA’s press release: UCLA life scientists and their colleagues have provided the first evidence of a causal link between traumatic brain injury and an increased susceptibility to post-traumatic stress disorder. Their new study . . . also suggests that people who suffer even a mild traumatic brain injury are [...]

We apparently get “dumber” with age, starting at middle age — not a new thought, but depressing nonetheless 0

From a reasonably large British study The British Medical Journal reported that: Longitudinal modelling of cognitive decline using three measures over 10 years provides robust evidence of cognitive decline at all ages between 45 and 70, even among those aged 45-49 at baseline The 10 year decline in reasoning was −3.5% in men aged 45-49 [...]
