As temperatures rise, so do insects’ appetites for corn, rice and wheat
Hotter, hungrier pests likely to do 10 percent to 25 percent more damage to grains for each warmer degree.
- Neuroscience
Newfound skull tunnels may speed immune cells’ trek to brain injuries
Minuscule channels connect the skull to the brain’s outer membrane, studies in mice and people show.

Hormones in the naked mole-rat queen’s poop turn subordinate nest-mates into surrogate parents.
- Animals
There’s method in a firefly’s flashes
Fireflies use their flashing lights for mating and maybe even to ward away predators.

Birthrates and immunity rates predict the spread of viruses that cause hand, foot and mouth disease.
- Neuroscience
How antibodies attack the brain and muddle memory
Human antibodies that target key brain proteins cause memory trouble when delivered into mice’s brains.
