New research is highly relevant to how antibodies are made in response to infections, vaccines and in autoimmunity due to the its analysis of a signal that is associated with hyper IgM syndrome, a genetic deficiency of CD40 ligand (CD40L) that results in profound immunodeficiency.
Read moreNew research reveals how nitrogen-fixing bacteria sense iron – an essential but deadly micronutrient. The findings are an important piece in the puzzle of how life deals with iron, a nutrient it cannot do without but one it must also avoid having in excess.

Read moreIn lemur society, it's not males but the females who are in charge. A new study of the role of hormones in aggression in lemurs from before birth to adulthood suggests female domination gets wired early, while lemurs are still in the womb.
Read moreCell biologists say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells.
Read moreStudies have shown that peanut oral immunotherapy (OIT) — ingesting small, controlled amounts of peanut protein — can desensitize adults and children and prevent allergic reactions, but the optimal duration and dose is unknown. In a study that followed participants after successful OIT, discontinuing OIT or continuing OIT at a reduced dose led to a decline in its protective effects. The study also found that blood tests administered before OIT could predict the success of therapy.
