Big and bold wasp queens may create more successful colonies
A paper wasp queen’s personality and body size could help predict whether the nest she has founded will thrive.
- Neuroscience
Imaging scans show where symbols turn to letters in the brain
Scientists watched brain activity in a region where reading takes root, and saw a hierarchy of areas that give symbols both sound and meaning.

Electrodes show a glimpse of memories emerging in a brain
Nerve cells in an important memory center in the brain sync their firing and create fast ripples of activity seconds before a recollection resurfaces.

Alzheimer’s targets brain cells that help people stay awake
Nerve cells in the brain that are tied to wakefulness are destroyed in people with Alzheimer’s, a finding that may refocus dementia research.
- Life
CRISPR enters its first human clinical trials
The gene editor will be used in lab dishes in cancer and blood disorder trials, and to directly edit a gene in human eyes in a blindness therapy test.
- Life
A mussel poop diet could fuel invasive carp’s spread across Lake Michigan
Asian carp, just a human-made waterway away from reaching Lake Michigan, could live in much more of the lake than previously thought.
- Humans
Even without concussions, just one football season may damage players’ brains
A group of college football players underwent brain scans after a season of play. The results suggest the sport could impact neural signaling.
- Neuroscience
Plants don’t have feelings and aren’t conscious, a biologist argues
The rise of the field of “plant neurobiology” has this scientist and his colleagues pushing back.

How these tiny insect larvae leap without legs
High-speed filming reveals how a blob of an insect can leap more efficiently than it crawls.

Why people with celiac disease suffer so soon after eating gluten
In people with celiac disease, some T cells release immune chemicals within hours of encountering gluten, triggering the fast onset of symptoms.
- Chemistry
A fungus makes a chemical that neutralizes the stench of skunk spray
A compound produced by fungi reacts with skunk spray to form residues that aren’t offensive to the nose and can be more easily washed away.
