Overcoming cardiovascular disease with a magnetically-steerable guidewire microrobot

Scientists have developed an attachable guidewire that can move and steer towards a desired direction inside complicated blood vessels. It is expected to contribute to increasing the success rate of heart disease treatment with a shorter cardiovascular disease surgery time and higher accuracy. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/03/190305100657.htm

Creating more potent cancer therapy using 'theranostics'

Scientists have developed a user-friendly approach to creating 'theranostics' -- therapy combined with diagnostics -- that target specific tumors and diseases. They have developed a novel method to prepare cell-penetrating nanoparticles called 'metallocorrole/protein nanoparticles.' The theranostics could both survive longer in the body and better snipe disease targets. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/03/190305100643.htm

Self-sterilizing microneedles revolutionizing vaccination and drug delivery

New technology is revolutionizing safe vaccination practices through antibacterial, silver-loaded dissolvable microneedle patches, which not only sterilize the injection site to inhibit the growth of bacteria, but also physically dissolve after administration. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/03/190305100640.htm

Physicists analyze rotational dynamics of galaxies and influence of the photon mass

The rotation of stars in galaxies such as our Milky Way is puzzling. The orbital speeds of stars should decrease with their distance from the center of the galaxy, but in fact they all have the same rotational speed. The physicists have hypothesized that the rotational dynamics of galaxies might be explained by the mass of photons, which are particles of light. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/03/190305100637.htm
