Britain has become the first country to license a fully tested covid-19 vaccine. The Economist’s health policy editor explains why this a historic milestone. Read more at Economist..

A new tool sponsored by the NIH may be helpful in keeping holiday gatherings -- or any other meeting -- as safe and as coronavirus-free as possible. Watch at CNN.

A team of engineers has demonstrated how a new algorithm they developed was able to successfully predict whether or not a COVID-19 patient would need ICU intervention. This artificial intelligence-based approach could be a valuable tool in determining a proper course of treatment for individual patients.

New research finds vibrations of the protein spikes on coronaviruses, including SARS-CoV-2, play a crucial part in allowing the virus to penetrate human cells. The findings could help determine how dangerous different strains or mutations of coronaviruses may be, and might point to a new approach to developing treatments.

3D bioprinted algae can be harnessed as a sustainable source of oxygen for human cells in engineered vascularized tissues, researchers report. They embedded the bioprinted photosynthetic algae, along with human liver-derived cells, in a 3D hydrogel matrix to create honeycomb-shaped tissues with lobules, similar to the human liver.

As news emerged this week that an experimental vaccine against covid-19 has proved effective in late-stage clinical trials, hopes that the pandemic’s days may be numbered are running high. Read more at Economist.

While immunotherapies work well for some cancers, others are immune-resistant and condemn patients to the severe side effects of long-term chemo treatment. A new cancer vaccine successfully treated immune-resistant breast cancer in mice, 100% of which survived a second injection of cancer cells, indicating long-term immunity with no side effects.

A new study lays out a large medical analytics framework that can be used in neuroscience and neurology to study brain connectivity in living organisms.

Scientists have developed a method to bioprint a type of cartilage that could someday help restore knee function damaged by arthritis or injury.
