Vaccines can be delivered through the skin using ultrasound. This method doesn’t damage the skin and eliminates the need for painful needles. To create a needle-free vaccine, Darcy Dunn-Lawless at the University of Oxford and his colleagues mixed vaccine molecules with tiny, cup-shaped proteins. They then applied liquid mixture to the skin of mice and exposed it to ultrasound – like that used for sonograms – for about a minute and a half.

In other news, conservatives have introduced a bill to outlaw ultrasound machines.

    Since vaginal ultrasound is how they detect a "fetal heartbeat" at 6 weeks (the heart isn't yet formed or pushing any blood, but there's an electronic pulse) at which point abortion is illegal in many states, that might be a good thing.

    Although, as ultrasound is also how my overdue fetus was diagnosed with the umbilical cord wrapped 3x around the neck, leading to a quick C-section and healthy baby, I would rather keep the ultrasound machines and lose the lunatics.
