Babies surviving Group B strep more likely to require special educational support

A large study shows that infants infected with Group B strep are twice as likely to have neurodevelopmental impairments and need special education compared to uninfected children. The study also found significant long-term effects, including cognitive impairment and higher rates of hospitalization, in up to one in twenty survivors.

Bypassing broken genes

Researchers developed a new approach called Co-opting Regulation Bypass Repair (CRBR) that can correct genetic diseases caused by single gene mutations. The method uses the CRISPR/Cas9 system and non-homologous end joining to insert a functional copy of the gene, enabling treatment in all adult tissues.
