Before the ubiquity of computers and high-speed internet and when the other options were snail mail or a courier, a fax could relatively quickly transmit medical records […]

Researchers engineer tiny machines that deliver medicine efficiently

“Theragrippers” are inspired by a parasitic worm that clamps onto its host’s intestines. When an open theragripper is exposed to internal body temperatures, it closes on the intestinal wall.

Researchers engineer tiny machines that deliver medicine efficiently — ScienceDaily

Inspired by a parasitic worm that digs its sharp teeth into its host’s intestines, Johns Hopkins researchers have designed tiny, star-shaped microdevices that can latch onto intestinal mucosa and release drugs into the body. David Gracias, Ph.D., a professor in the Johns Hopkins University Whiting School of Engineering, and Johns Hopkins gastroenterologist Florin M. Selaru, […]

Deep sea coral time machines reveal ancient CO2 burps — ScienceDaily

The fossilised remains of ancient deep-sea corals may act as time machines providing new insights into the effect the ocean has on rising CO2 levels, according to new research carried out by the Universities of Bristol, St Andrews and Nanjing and published today [16 October] in Science Advances. Rising CO2 levels helped end the last […]
