Mosquitoes seem to prefer some flavors over others. Knowing what they like — and hate — could lead to better ways to prevent bites.
Neurons in the brain forge new connections and sometimes trim back old ones. This capacity for change allows us to learn new skills and recover from injury.
Treating weakened fruit flies with an herb-drug combo was more effective than the usual drug-only treatment.
The current way to produce antivenoms is outdated. In lab tests, AI-designed proteins could save mice from a lethal dose of snake toxin.
The outbreak shows that a near absence of once-common childhood diseases — like measles — is not evidence that vaccines are unnecessary.
Our autonomic nervous system balances two natural responses. If stressed or overwhelmed, simple techniques can help to restore that balance.
A lot of their old-fashioned dioramas — a type of exhibit — are biased, boring or even unscientific. Here’s what modern museums are doing to fix that.
Tissue from the memory centers of people’s brains reveal relatively few links among nerve cells in the hippocampus. But they carried strong, reliable signals.
Someday, technology might be able to help people better hold onto memories or forget bad ones.
