DGIST research team succeeded in developing a microrobot that can reach the accurate location of cardiovascular disease such as the Chronic Total Occlusion by moving and steering the microrobot towards a desired direction inside complicated blood vessels. This research is expected to increase the success rate of treatment and shorten the time of cardiovascular disease surgery.

DGIST announced on February 27 that Professor Hongsoo Choi’s team in the Robotics Engineering Department developed the ‘Magnetically Controlled Microrobot’ that can enhance the success rate of CTO treatment among myocardial infarctions through a...

New material could mean fewer trips to the dentist’s office, scientists report. A compound used to make car bumpers strong and protect wood decks could prevent return visits to the dentist’s office. A team of researchers with the OHSU School of Dentistry in Portland, Oregon, have created a filling material that’s two times more resistant to breakage than standard fillings, according to a study published by the journal Scientific Reports. The new filling uses the additive thiourethane, which is also in protective coatings for cars and decks.

The team also has developed an adhesi...

Scientists have been able to rejuvenate stem cells in the brain of aging mice. The revitalised stem cells improve the regeneration of injured or diseased areas in the brain of old mice...

Unusual property of the ultrastrong material could be harnessed for twisting or pulling motions. Researchers have found that spider silk produces a strong twisting motion when exposed to humidity, and may be usable for future artificial muscles or actuators. Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.

The resilient fibers, the team discovered, respond very strongly to ...
