Triplet Threat from the Sun

JCP-Rizzo-photodamage.jpg

The most obvious effects of too much sun exposure are cosmetic, like wrinkled and rough skin. Some damage, however, goes deeper—ultraviolet light can damage DNA and cause proteins in the body to break down into smaller, sometimes harmful pieces that may also damage DNA, increasing the risk of skin cancer and cataracts. Understanding the specific pathways by which this degradation occurs is an important step in developing protective mechanisms against it.

Endocrine-Disrupting Chemicals Alter Thyroid Hormone Activity During Pregnancy

A new study in human placenta provides the strongest evidence to date that Endocrine Disrupting Chemicals (EDCs) can interfere with thyroid hormone action in pregnant women. The implication is that flame retardant chemicals called polychlorinated biphenyls (PCBs) can infiltrate the placenta during pregnancy and affect thyroid hormone activity at the cellular level, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).

Dog Waste Contaminates Our Waterways

ACS10-1-2014IMAGE3.png

Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria — including antibiotic-resistant strains — that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern, according to a report in the ACS journal Environmental Science & Technology.
