Despite abundant evidence supporting their ability to help prevent and treat cardiovascular disease, the therapeutic effectiveness of fish oil–derived fatty acids remains controversial.

Aberrant immune activation, the main cause of prematurity and stillbirths, could be preventable through interventions such as maternal vaccination. 

Science gets personal as researchers—professional and amateur—plumb the depths of their own molecular biology.

From a rapid molecular test for COVID-19 to tools that can characterize the antibodies produced in the plasma of patients recovering from the disease, this year’s winners reflect the research community’s shared focus in a challenging year.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.

How the Lysophospholipid Got its Receptor The discovery of a new family of lipid receptors provides potential targets for diseases such as multiple sclerosis and autoimmunity. By Jerold Chun Related Articles 1 By the late 1960s, researchers had become aware that this somewhat obscure class of lipids had the remarkable ability to act like an extracellular signaling molecule.2 Two prominent forms typify but do not limit lysophospholipids: lysophosphatidic acid

Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.

By Judy Lieberman Master of the Cell RNA interference, with its powerful promise of therapy for many diseases, may also act as a master regulator of most—if not all—cellular processes. RNA silencing.

Aminoacyl-tRNA synthetases, which help translate the genetic code into protein, also function in angiogenesis, fat metabolism, and more.
