Maintaining an open airway is a critical priority in emergency medicine. Without the flow of oxygen, other emergency interventions can become ineffective at saving the patient’s life. However, creating this airway through endotracheal intubation is a difficult task for highly trained individuals and under the best of circumstances.

In a three‐year study involving more than 5,000 residents of Israel before and after the mass traumatic events of October 7, 2023, those who watched extensive media coverage of the attacks were found to be more likely to develop post‐traumatic stress disorder (PTSD).

A new method to keep human lymph node tissue alive and functioning outside the body for several days could give researchers a much clearer view of how our immune system responds to infections, vaccines and cancer, without the need for preclinical modeling or over-simplified laboratory models.

A team of researchers from Johns Hopkins University, Boston University, and collaborators has now demonstrated a new type of fundus camera that removes one of the main challenges: focusing. Instead of relying on mechanical adjustments of a lens, the system uses a special diffuser that captures 3D light information during imaging. With this data, a computer can reconstruct and refocus images after they are taken.
