NIH researchers develop MRI with lower magnetic field for cardiac and lung imaging condition

Researchers at NIH and Siemens developed a low-magnetic-field MRI system that improves image quality of lungs and other internal structures, making medical imaging more affordable and accessible. The new system also reduces the risk of heating and allows for safer procedures for patients with pacemakers or defibrillators.

Stem cell treatments for shoulder and elbow injuries flourish, but so far there's little evidence they work

Researchers warn that stem cell therapies for shoulder and elbow injuries have far outpaced supporting scientific data, with many treatments still unproven. The clinical data for these treatments are currently limited, and a greater understanding of optimal formulations and dosing schedules is needed to determine their effectiveness.

2,000 atoms in two places at once

Researchers at the University of Vienna and University of Basel successfully create a quantum superposition in hot, complex molecules composed of nearly 2,000 atoms. The experiment sets new constraints on alternative theories to quantum mechanics, demonstrating the robustness of quantum mechanics on a macroscopic scale.

Handling traumatic grief reactions in children and adolescents post-9/11

A new study found that traumatic grief reactions in youth post-9/11 warrant separate clinical attention. The study, published in the Journal of the American Academy of Child and Adolescent Psychiatry, identified a distinct bereavement-related disorder that captures maladaptive reactions after 9/11.
