In surprising twist, some Alzheimer’s plaques may be protective, not destructive
April 15, 2021
One of the characteristic hallmarks of Alzheimer's disease (AD) is the buildup of amyloid-beta plaques in the brain. Most therapies designed to treat AD target these plaques, but they've largely failed in clinical trials. New research upends conventional views of the origin of one prevalent type of ...

Study strengthens links between red meat and heart disease
April 15, 2021
An observational study in nearly 20,000 individuals has found that greater intake of red and processed meat is associated with worse heart function.
Housing experience affects adult neurogenesis in turtles (<em>Chrysemys picta</em>).
April 15, 2021
Adult neurogenesis increases in mammals when they are exposed to an enriched environment or given the opportunity to exercise. In this experiment, we investigated whether turtles would show differences in the number of new neurons in the telencephalon when they were exposed to deep water, conspecifi...

Hippocampal volume varies with acute posttraumatic stress symptoms following medical trauma.
April 15, 2021
The hippocampus and amygdala play an important role in the pathophysiology of posttraumatic stress disorder (PTSD). In fact, chronic PTSD has been consistently linked to reductions in hippocampal and amygdala volume. However, the acute impact posttraumatic stress has on the volume of these brain reg...

Time or place? Dissociation between object-in-place and relative recency in young APPswe/PS1dE9 mice.
April 15, 2021
This study tests the predictions of a novel analysis of recognition memory based on a theory of associative learning, according to which recognition comprises two independent underlying processes, one relying on the to-be-recognized item having been experienced recently (self-generated priming), and...

Spatial learning in male and female Long-Evans rats.
April 15, 2021
Male and female Long-Evans rats were tested in the Morris water maze at 6 months of age. A place training procedure, in which rats learned the position of a camouflaged platform, was followed by cue training, in which rats escaped to a visible platform. No sex difference was found in place learning ...

Power of light and oxygen clears Alzheimer’s disease protein in live mice
April 13, 2021
A small, light-activated molecule recently tested in mice represents a new approach to eliminating clumps of amyloid protein found in the brains of Alzheimer's disease patients. If perfected in humans, the technique could be used as an alternative approach to immunotherapy and used to treat other di...
