A Close-up of COVID-19 in Lung Cells
If you or a loved one have come down with SARS-CoV-2, the coronavirus responsible for COVID-19, you know it often takes hold in the respiratory system. This image offers a striking example of exactly what happens to cells in the human airway when this coronavirus infects them.
DOCLINE: Connecting Medical Libraries for 35 Years
Guest post by Lisa Theisen, Head of NLM’s Collection Access Section and Elisabeth (Lis) Unger, NLM DOCLINE Team Lead It’s been 35 years since NLM’s interlibrary loan (ILL) request routing system, DOCLINE®, was launched with a goal of enabling medical libraries to get biomedical literature into the hands of people who need it as efficiently and …
New Online Resource Shows How You Can Help to Fight COVID-19
There are lots of useful online resources for people to learn about COVID-19 and some of the clinical studies taking place across the country. What’s been missing is a one-stop online information portal that pulls together all the most-current information for people of all groups, races, ethnicities, and backgrounds who want to get involved in helping to combat the pandemic.
