In March 2017, the Cardiovascular Surgery Group at Osaka University successfully implanted a left ventricular assist device with an internal power cable tunneled through the neck to the head in a patient who was ineligible for a cardiac transplantation, destination therapy (DT) trial, a Japan first. The patient was recently discharged.

Researchers at Osaka University develop a high-speed serial-sectioning imaging system that captures high-resolution images of a whole mouse brain and furthers our understanding of brain diseases in rodents and primates. To fully understand brain function and dysfunction, it is important to be able to visualise changes in anatomy and activity in the whole brain.

A group of researchers led by Osaka University developed an early detection method for cow lameness (hoof disease), a major disease of dairy cattle, from images of cow gait with an accuracy of 99% or higher by applying human gait analysis. This technique allows early detection of lameness from cow gait, which was previously difficult. It is hoped that a revolution in dairy farming can be achieved through detailed observation by AI-powered image a...

An international research team led by Osaka University together with Tokyo Metropolitan University, imec in Belgium and Crimson Technology has released a machine-learning device that detects the emotional state of its listeners to produce new songs that elicit new feelings. "Most machine songs depend on an automatic composition system," says Masayuki Numao, professor at Osaka University. "They are preprogrammed with songs but can only make s...

  A group of Japanese researchers developed a prototype construction robot for disaster relief situations. This prototype has drastically improved operability and mobility compared to conventional construction machines.

Researchers at Osaka University developed a technology to control the light wavefront reflected from a cholesteric liquid crystal - a liquid crystal phase with a helical structure. Although known for their ability to Bragg-reflect light, cholesteric liquid crystals could only be used as flat mirrors, reflecting light at the same angle as the incident angle. The new technology enables planar optical components to be made with functionality by desi...

An international research group observed a state in copper oxides in which orbital degrees of freedom did not freeze at low temperatures and electrons fluctuated due to quantum fluctuations. The group also clarified the time scale of these quantum fluctuations in multifrequency electron spin resonance (ESR) experiments in a strong magnetic field for the first time. Electrons have three degrees of freedom: spin, orbital, and electric charge.
