Microplastics Detected in Human Placenta Samples

A flurry of recent studies has found that microplastics are present in virtually everything we consume, from bottled water to meat and plant-based food. Now, University of New Mexico Health Sciences researchers have used a new analytical tool to measure the microplastics present in human placentas.

In a study published February 17 in the journal Toxicological Sciences, a team led by Matthew Campen, PhD, Regents' Professor in the UNM Department of Pharmaceutical Sciences, reported finding microplastics in all 62 of the placenta samples tested, with concentrations ranging from 6.5 to 790 micrograms per gram of tissue.  READ MORE...

Oxytocin Influences Animal Behavior

Oxytocin (OXT) is a hormone that is known for its effects on psychological well-being and emotional bonding in animals. Interestingly, research has shown that this natural chemical in the brain plays a crucial role in other cognitive processes as well, including learning and memory. 

Now, scientists may have discovered exactly how OXT influences memory in animals by studying "OXT neurons" that contain OXT receptors and function differently based on the availability of the chemical in the brain.  READ MORE...
