SARS-CoV-2 Immunity Rapidly Declines Within Months of Infection
A recent preprint study indicates that there is a rapid decline in the levels of SARS-CoV-2 neutralizing antibodies during the weeks following initial infection. This raises questions over the potential for re-infection, the effectiveness that may be expected from vaccination and the viable window for antibody testing in disease surveillance.

Blood-based Biomarkers Can Help To Predict Recurrence of Triple Negative Breast Cancer
Indiana University School of Medicine researchers have discovered that the presence of circulating tumor DNA and circulating tumor cells in the plasma of women's blood who have undergone chemotherapy prior to surgery for the treatment of stage 1, 2 or 3 triple negative breast cancer are critical indicators for the prediction of disease recurrence and disease-free survival.

No NELL2, No Sperm Motility
Researchers have discovered a novel testicular luminal protein, NELL2, that triggers in the epididymis a chain of events that matures the sperm and enables each one to be motile in females.

Blood-based Biomarker Can Detect and Predict Severity of Traumatic Brain Injury
A study from the National Institutes of Health confirms that neurofilament light chain as a blood biomarker can detect brain injury and predict recovery in multiple groups, including professional hockey players with acute or chronic concussions and clinic-based patients with mild, moderate, or severe traumatic brain injury.

COVID-19 Could Outwit Science Unless Knowledge Stays Current
The virus that causes COVID-19 has many variants, and if scientists don’t stay on top of how it is changing in different parts of the world, testing for it may produce false negative results.
