Nutrient Deprivation Induces Embryonic Diapause in Hungry Mouse Mums

It's challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That's why many mammalian embryos can postpone their growth to get through periods of environmental stress and then re-enter development when conditions improve.

Embryonic Cells Pressed into Organizers: Mechanism Unveiled

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children's in Los Angeles has identified a mechanism by which embryonic cells organize themselves to send signals to surrounding cells, telling them where to go and what to do.

Groundbreaking Physics Study Offers Insights Into Self-Organization of Biological Particles

Erin McCarthy '23, physics summa cum laude, is a rarity among young scientists. As an undergraduate researcher in Syracuse University's College of Arts & Sciences' Department of Physics, she guided a study that appeared in March 2024 in Physical Review Letters. It is the most-cited physics letters journal and the eighth-most cited journal in science overall.
