Scientists are now combining living human neurons with silicon hardware to create programmable biological computers. The cells can receive information, adapt their activity and communicate back to software, raising both extraordinary computing possibilities and new ethical questions. The post A computer using living human neurons could point to a radically more efficient future for AI appeared first on Research Today.

Some people remained cognitively resilient despite carrying greater Alzheimer’s-related pathology. A 15-year study found that resilience predicted dementia risk almost as strongly as the disease markers themselves.

Researchers developed a lithium-metal battery exceeding 500 Wh/kg that survived fully charged nail penetration without catching fire. The technology also retained 80% capacity after 800 cycles, although significant work remains before commercial use. The post This battery could help solve the EV industry’s hardest trade-off: more range without more fire risk appeared first on Research Today.

Tariffs may be imposed at one country's border, but their effects can travel around the world. New research found that 92% of the 2025 US tariff increase reached import prices, while earlier US-China tariffs unexpectedly created jobs in countries such as Vietnam and Brazil.
