A comprehensive map of how Alzheimer's affects the brain

Researchers analyzed postmortem brain samples from 24 people with Alzheimer's and 24 without the disease to identify cellular pathways affected by the disease. The study found that axon myelination is disrupted in patients, and gene expression patterns vary significantly between men and women, suggesting potential new drug targets.

Vaccination may help protect bats from deadly disease

A new study suggests that vaccination could reduce the impact of white-nose syndrome in bats by providing immunity against the fungus Pseudogymnoascus destructans. Bats immunized against Pd were less likely to develop WNS or die from the disease in two initial scientific trials.

Lure of the 'loot box' looks a lot like gambling

A new study by University of British Columbia researchers found a correlation between excessive engagement with loot boxes and measures of problem gambling, but not problem video gaming. Loot box use was associated with risky gambling behaviours, suggesting that the feature may be contributing to gambling-like problems in gamers.
