Nanoparticle systems crucial for new high-speed devices demonstrated — ScienceDaily

For the first time researchers have demonstrated a new way to perform functions essential to future computation three orders of magnitude faster than current commercial devices. The team lead by Associate Professor Shinobu Ohya, created a nanoscale spintronic semiconductor device that can partially switch between specific magnetic states trillions of times a second (terahertz —…

Self-sterilizing microneedles revolutionizing vaccination and drug delivery — ScienceDaily

Vaccinations are the world’s frontline defence against infectious diseases yet despite decades of interventions, unsafe injection practices continue to expose billions of people to serious infection and disease. Now, new technology from the University of South Australia is revolutionising safe vaccination practices through antibacterial, silver-loaded dissolvable microneedle patches, which not only sterilise the injection site…

Overcoming cardiovascular disease with a magnetically-steerable guidewire microrobot — ScienceDaily

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…

‘Test and Treat’ reduces new HIV infections by a third in southern Africa communities — ScienceDaily

New HIV infections in southern Africa could be reduced substantially by offering entire communities voluntary HIV testing, and immediately referring those who test positive for HIV treatment in line with local guidelines, according to new research presented at the Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle, USA today. The HPTN071 (PopART) trial found…
