First-ever views of elusive Energy Explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving “magnetic reconnection” – the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion – in the Earth’s magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can have – sparking auroras and possibly wreaking havoc on power grids in the case of extremely large events – but they haven’t completely understood the details...

A new approach to Detecting Cancer earlier from Blood Tests

Cancer scientists led by principal investigator Dr. Daniel De Carvalho at Princess Margaret Cancer Centre have combined “liquid biopsy,” epigenetic alterations and machine learning to develop a blood test to detect and classify cancer at its earliest stages. The findings describe not only a way to detect cancer, but hold promise of being able to find it earlier when it is more easily treated and long before symptoms ever appear, says Dr. De Carvalho, Senior Scientist at the cancer centre, University Health Network.

“We are very excited at this stage,” says Dr. De Carvalho. “A major problem in cancer is how to detect it early...

Solar Panels for Yeast Cell Biofactories

The researcher's model of a yeast cell (magenta) with semiconductor nanoparticles (purple) attached to its surface (left) corresponds with their SEM analysis of the completed biohybrid system (right). The semiconductors capture electrons from light and hand them over to the cell where they drive the shikimic acid metabolic pathway. Credit: Wyss Institute at Harvard University

Moths and Magnets could Save Lives

Rice University bioengineers use a magnetic field to activate nanoparticle-attached baculoviruses in a tissue. The viruses, which normally infect alfalfa looper moths, are modified to deliver gene-editing DNA code only to cells that are targeted with magnetic field-induced local transduction.

Experimental therapy could repair mutations that cause genetic diseases. Bioengineers have combined a virus that infects moths with magnetic nanoparticles to create a potential new therapy for inherited genetic diseases like muscular dystrophy, sickle cell, cystic fibrosis, spinal muscular atrophy and some forms of cancer.

Rice University bioengineer Gang Bao has combined magnetic nanoparticles with a viral container drawn ...
