People with self-reported poorer mental health also report worse quality of care and lower confidence in healthcare systems, according to a study published May 5^th in the open-access journal PLOS Medicine by Margaret E. Kruk from Washington University in St. Louis, U.S., and colleagues.

The H5N1 strain of highly pathogenic avian influenza H5N1 has been detected in over 700 herds of dairy cows in California, the largest dairy-producing state in the U.S. A study published May 5^th in the open-access journal PLOS Biology led by Seema S. Lakdawala at Emory University School of Medicine, U.S. and Jason Lombard at Colorado State University, U.S. suggests that avian influenza (H5N1) is transmitted through multiple, previously unknown sources and that some H5N1 positive cows do not show clinical signs of infection.

Only 43% of menu items at the UK’s highest-grossing restaurant chains met all their voluntary targets for sugar, salt, and calorie reduction, as set by the UK Government. These findings are published on May 5^th in a study in the open-access journal PLOS Medicine by Alice O’Hagan of the University of Oxford, UK, and colleagues.

Researchers have developed methods using induced pluripotent stem cells and CRISPR gene editing to evaluate how genetic variants elsewhere in an individual's genome — their genetic background — work with a deletion on chromosome 16 that is associated with various neurodevelopmental outcomes to help determine the features that the individual will develop.

A total of 221 schools across early childhood, elementary, middle and high school levels have earned Colorado Asthma-Friendly School recognition. This new recognition underscores each school’s commitment to comprehensive asthma management and student health throughout the 2025-2026 school year and connects them to a growing local network through the Colorado Comprehensive School-Centered Asthma Program (AsthmaCOMP), supported by Children’s Hospital Colorado (Children’s Colorado).

Concordia researchers developed a high-fidelity CPR simulator that replicates blood flow in reduced gravity, using a mannequin with a 3D-printed cardiovascular system. Tests in parabolic flights showed it reproduces realistic pressure patterns while revealing key differences in blood flow under hypogravity, helping improve CPR techniques for future space missions.
