The reproductive biologist uncovered hormones important for fertility cycles.

The effects occurred after rodents consumed the chemical in levels 10- or 20-fold below the recommended daily dose for humans.  

The pre-peer review assessment finds the compound has “minimal effects,” but endocrinologists and others say key data have yet to come out.

Decades of evidence point to the untoward health effects of endocrine disruptor exposures, yet little is being done to regulate the chemicals.

Lab studies suggest that plastic pollutants in the environment could have detrimental effects on animals’ physiology.

Melvin Grumbach, a clinician and researcher who described the hormonal dynamics of puberty and numerous endocrine disorders, has passed away at age 90.

Two studies add to the evidence that replacements for the plastic additive affect cells and animals in the same, untoward ways as bisphenol A.

Factors that likely contribute to obesity include disruptions to intercellular signaling, increased inflammation, and changes to the gut microbiome.
 

Leptin, the satiety hormone produced by fat, affects neuronal signaling in the mouse brain; interference with this pathway can influence the rewarding effects of running in the animals.
