Quantum vacuum: Less than zero energy

A research team investigated the possibility of negative energy in quantum physics, finding that while energy can be less than zero under certain conditions, it must be paid back. The study placed tight bounds on negative energy and connected it to quintessential properties of quantum mechanics.

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.
