How intelligent is artificial intelligence?

AI systems often employ 'Clever Hans' strategies that are not meaningful from a human perspective, but still achieve success. Researchers have developed explainable AI technology to identify these flawed strategies and identify more intelligent problem-solving approaches.

Parkinson's treatment delivers a power-up to brain cell 'batteries'

A new study suggests that deep brain stimulation boosts the number and strength of mitochondria in brain cells, which may help reduce Parkinson's symptoms. The treatment, used for late-stage Parkinson's disease, involves surgically implanting thin wires into the brain to deliver small electric pulses.

Discovery upturns understanding of how some viruses multiply

Researchers have found that different segments of a virus genome can exist in distinct cells but still cause an infection, contradicting a long-held model. The study, published in eLife, used fluorescent probes to detect viral segments in individual cells and found that distinct segments are often found in different cells.

Breath of fresh air in vasculitis research

Researchers have identified an association between a MUC5B gene variant and systemic vasculitis, a lung disease prevalent in the Japanese population. The study found that patients with antineutrophil cytoplasmic antibody-associated vasculitis are more likely to have ILD if they carry this specific genetic variation.
