Battery-Free Light-Powered Pacemaker Now a Reality
Researchers at the University of Arizona have developed a battery-free light-powered pacemaker that uses optogenetic stimulation of cardiomyocytes to achieve heart pacing. With conventional pacemakers, the leads of the device are anchored into...

mRNA Therapy Prevents COVID Virus Entering Cells
Scientists at Oregon State University have developed a new treatment for COVID-19. The technology is based on mRNA, which has also been put to good use in COVID-19 vaccines. However, in this instance, the delivered mRNA encodes for human...

Scientists Teach Neurons to Play Pong
Scientists at Cortical Labs in Melbourne, Australia, along with international collaborators, have developed “DishBrain”, which is essentially a collection of neurons in a dish that have demonstrated learning and, incredibly, can play the...

CRISPR-Cas13 System for Quick and Sensitive SARS-CoV-2 Detection
Scientists at Rice University created a rapid COVID-19 test that is based on the gene editing CRISPR-Cas system. The researchers modified the Cas-13 protein to increase its activity and to light up with fluorescence when it encounters RNA from...

DNA Nets Capture Sars-CoV-2 for Detection and Inhibition
A team at the University of Illinois at Urbana-Champaign has developed a DNA net system that can ensnare Sars-CoV-2 and bind to the notorious spike protein. The nets contain aptamers that bind the spike protein and emit an intense fluorescent...

Nanorattles for Rapid Detection of Multiple mRNA Cancer Biomarkers
Scientists at Duke University have developed a ‘nanorattle’ system that allows for the detection of mRNA biomarkers of cancer. The tiny structures consist of gold nanospheres with a surrounding silver nanocage, forming the so-called rattle....
Genetics
Microfluidic Device Mimics Embryonic Heartbeat to Stimulate Stem Cell Development
Scientists at the University of New South Wales in Australia have developed a method to produce human blood stem cell precursors from human pluripotent stem cells. The method may have use in treating cancer patients who require high doses of...

DNA-Based Nanorobot Interacts with Live Cells
Researchers at INSERM (Institut national de la santé et de la recherche médicale) in France, and collaborators, have developed a DNA-based nanorobot called the Nano-winch. The tiny creation is made using DNA molecules and a “DNA Origami”...
