In a breakthrough that is sure to thrill optical ailment sufferers and stoners everywhere, a team of Auburn University researchers has invented a new kind of drug-delivering contact lens that could make the medicinal eye drop a thing of the past. Their lenses are the first to deliver drug doses evenly for as long as the lens is worn, a method that is roughly 100 times more effective than putting sporadic eye drops in the eye.
This summer's crippling famine in Somalia, which has killed tens of thousands of people and led half a million more to seek refuge in Kenya, is notable for many reasons — but the theft and sale of life-saving aid is arguably one of the worst. A new project could be one way to prevent such atrocity in the future: Use drones to drop food and drugs right where they're needed, no human intervention required. Enter the Matternet.
A pair of magnetic liquid drops oscillating in opposite directions can function as a liquid piston, and could one day be used to deliver drugs, power mobile phone cameras or even serve as implantable eye lenses, according to a new study.

For patients with conditions like cancer, diabetes and chronic pain, taking drugs orally is often insufficient; a more precise and flexible on/off dosing schedule controlled by an implanted device can provide better treatment based on day-to-day--or minute-by-minute--conditions.
While various methods for regulating drug-dispensing implants exist (including implanted heat sources and electronic chips), a new device with a membrane of magnetic nanoparticles can be controlled simply by applying a magnetic field.
Scientists say ultrasmall man-made particles are toxic to animals. What about us?

In 1941, researchers at Johns Hopkins Hospital made an unsettling discovery: Inhaled nanoscopic particles could travel into the brain. When chimps and rhesus monkeys breathed air laden with poliovirus cells, some of the particles followed the path normally reserved for smell signals, thwarting the protective blood-brain barrier.
