Can AI fix the peer review bottleneck? Top journals weigh in

Study examines AI's role in peer review among top 100 medical journals, revealing that while most journals provide AI guidelines, a majority prohibit its use due to confidentiality and ethical concerns. The findings highlight varied policies and emphasize the need for clear, unified guidance for AI integration in peer review.

Study identifies key immune cells that could protect the brain after cardiac arrest

Despite improvements in CPR and rates of getting patients to the hospital, only about 10 percent of people ultimately survive after out-of-hospital cardiac arrest (OHCA), translating to about 300,000 deaths per year in the United States.
