Children exposed to low to moderate levels of prenatal alcohol showed characteristic facial changes that persisted until age 6 or 8. No linear association between alcohol exposure and facial shape was found, suggesting other factors at play.
A new study published in JAMA found that pulmonary vein isolation combined with ethanol infusion of the vein of Marshall significantly improved freedom from atrial arrhythmias within 12 months. This approach outperformed traditional pulmonary vein isolation alone in reducing AF recurrence rates.
Researchers have developed a diffractive optical processor that can compute hundreds of transformations in parallel using wavelength multiplexing. The processor, which is powered by light instead of electricity, can execute multiple complex functions simultaneously at the speed of light.
