A team of McGill University researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment.

These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult. The 3D-printed HoLDI-MS test platform overcomes the limitations of traditional mass spectrometry by enabling direct analysis of samples without requiring complex sample preparation. The researchers say it also will work for detection of waterborne plastic particles. HoLDI-MS stands for hollow-laser desorption/ionization mass spectrometry.

A new commentary published in Annals of Internal Medicine from Roy Gulick, MD, Chief, Division of Infectious Diseases and Professor of Medicine at Weill Cornell Medicine, highlights what’s new in the updated CDC HIV Non-Occupational Post Exposure Prophylaxis (nPEP) Guidelines.

A new Emory University study reports a substantial increase in the percentage of mental health and neurodevelopmental disorder diagnoses among publicly insured children in the United States.

In new research published in Nature, researchers from the University of Chicago show how mice fed a Western-style diet are not able to rebuild a “healthy,” diverse gut microbiome following antibiotic treatment. These mice were also more susceptible to infection by pathogens like Salmonella. However, mice given food loosely mimicking a Mediterranean diet—high in plant-based fiber from fruits, vegetables, and whole grains—were able to quickly restore a healthy and resilient gut microbiome after antibiotics.

Half of U.S. adults say they know eating a plant-based diet can improve their health and help prevent chronic diseases, according to a new Physicians Committee for Responsible Medicine/Morning Consult survey. However, the survey also showed that just 1 in 5 primary care practitioners discuss this lifesaving message with patients.
