UNIVERSITY OF BIRMINGHAM Scientists at the University of Birmingham have developed a new sensor to measure weak magnetic signals in the brain, which has the potential to increase understanding of connectivity in the brain, and detect signs of traumatic brain injury, dementia and schizophrenia. Magnetic signals in the brain are measured by magnetoencephalography (MEG). They...

Folding of SARS-CoV2 genome reveals drug targets — and preparation for ‘SARS-CoV3’
GOETHE UNIVERSITY FRANKFURT The genetic code of the SARS-CoV2 virus is exactly 29,902 characters long, strung through a long RNA molecule. It contains the information for the production of 27 proteins. This is not much compared to the possible 40,000 kinds of protein that a human cell can produce. Viruses, however, use the metabolic processes...

Super-porous material transports cancer-killing CRISPR inside cells
By Michael Irving; November 22, 2020 A new study has shown how metal organic frameworks (MOFs) can be used to carry the CRISPR gene-editing tool into cancer cells The CRISPR/Cas9 gene-editing tool has shown promise in treating a wide range of diseases, but getting it into cells in the first place can be challenging. Now, researchers in...
