Over 19 years, geomagnetic fields changed slightly and so did loggerheads’ nesting sites.
- Neuroscience
Brain’s plumbing may knock out blood test for brain injury
The brain's waste-removal system may complicate scientists' attempts to create a blood test to diagnose traumatic brain injury.

Tricky pitcher plants lure ants into a false sense of security
Carnivorous pitcher plants exploit social lives of ants as scouts escape and inadvertently lead nest mates to death trap.
- Neuroscience
Protectors of our nervous system play a role in pain
PET and MRI brain scans show that the cells that protect our central nervous system also play a role in chronic pain.
