In what is claimed as the first co-authored research between regulatory scientists at the U.S. FDA and a commercial manufacturer of organ-on-a-chip devices, CN Bio's Physiomimix system is shown to perform better than the current standard in vitro liver toxicity tests. In addition to maintaining its function for longer than 2D hepatocyte cultures or 3D spheroids, Physiomimix was found to reproducibly assess toxicity, metabolism and intracellular accumulation of drugs.
LONDON – A new national consortium of virologists has been set up to systematically assess how mutations in SARS-CoV-2 affect key outcomes such as effectiveness of vaccines and therapies, transmissibility of the virus and the severity of COVID-19 infections.

Transient gene editing of the herpes simplex virus type 1 using mRNA-based CRISPR was shown for the first time to be effective against herpetic stromal keratitis in mice and blocked HSV-1 replication in human corneas, Chinese researchers reported in the January 11, 2021, online edition of NatureBiotechnology.
Alzheimer’s disease can be divided into multiple subtypes based on gene expression patterns, investigators at the Mount Sinai School of Medicine reported in the Jan. 6, 2021, issue of Science Advances. The work, corresponding author Bin Zhang told BioWorld, is “the first major finding of subtypes in Alzheimer’s disease.”

LONDON – A new national consortium of virologists has been set up to systematically assess how mutations in SARS-CoV-2 affect key outcomes such as effectiveness of vaccines and therapies, transmissibility of the virus and the severity of COVID-19 infections. Now is the critical time to do this, as the level of both natural and vaccine-conferred immunity that might drive natural selection is increasing, said Wendy Barclay, head of the department of infectious disease at Imperial College London, who is leading the G2P-UK (Genotype to Phenotype-UK) project.
Aging, which is associated with various pathologies such atherosclerosis and cancer, is characterized by an accumulation of senescent cells. Cellular senescence blocks cell proliferation, but it decreases the health of the old by littering tissues with dysfunctional senescent cells.
