“Pregnancy Interrupted: The Science and Stories of How Pregnancies Really End,” describes the intricate, trial-and-error process of egg production, fertilization, implantation and growth as a series of precisely timed structural and hormonal events that allow a placenta to form and nurture a growing embryo. While this progression is never perfect, the pregnant body and the embryo or fetus must pass certain developmental milestones before they can progress to the next stage.

A new study reveals that oncogenic signaling can reshape cancer cells not only by changing gene activity, but also by changing how cellular machinery reads the genetic code.

Traditional field research combined with new technology has revealed a secret to the survival of juvenile salmon as they form in their eggs, especially in low-water years when many do not survive, new research from NOAA Fisheries and the University of California, Davis shows.

This study, published in Eye & ENT Research, compared LASIK surgery and contact lenses for myopia correction through a systematic review and meta-analysis of four studies with 2,141 participants. The key findings show that LASIK users report much higher satisfaction (88% vs. 54%) and have fewer complications (6.7%–9.5% vs. 19.9%) than contact lens wearers. However, LASIK causes more acute dry eye after surgery, while contact lenses lead to more chronic dry eye over time. Quality of life results were unclear due to differences in how studies measured it.
