This research reveals how Streptococcus evades immune attack by shedding its hair-like surface proteins, distracting immune cells while provoking excessive immune activation. The findings provide a new explanation for how recurrent strep infections can trigger autoimmune diseases and suggest treatments should target both the bacteria and the immune response.

This research studies a bacterial enzyme called Huc that can generate electricity from trace amounts of hydrogen in the air. By revealing how this nickel-and-iron enzyme captures and converts hydrogen efficiently, the work could inspire low-cost clean energy technologies that reduce reliance on fossil fuels and support a more sustainable future.
