(CNN) — Exposure to a chemical commonly used to reduce bacterial contamination in cosmetics, toothpaste and products like toys and clothing may come with an unintended risk — osteoporosis. That’s according to a study in Tuesday’s Journal of Clinical Endocrinology & Metabolism.

The study looked at data from 1,848 women between 2005 and 2010 and found that women who had higher levels of triclosan in their urine were more likely to develop osteoporosis later on in life. Osteoporosis is a metabolic bone disease in which a person loses bone mineral density. With the bones weakened, it puts a person at an increased risk for fractures, back pain and loss of height.

This the first such study to find this connection, researchers said.

Proteins dating back more than one million years have been extracted from some fossils, and could help to answer some difficult questions about archaic humans.

Today, we want to highlight a new publication that looks at cytomegalovirus (CMV) and its potential role in the development of metabolic syndrome, the precursor to type 2 diabetes.

What is cytomegalovirus?

CMV is part of the β-subfamily of herpes viruses, a family of viruses that are believed to have been co-evolving with their hosts for around 180 million years [1]. CMV is spread primarily by exposure to infected secretions and subsequent mucosal contact, which then leads to the acute infection of various cell types. After this acute infection, in which the virus spreads, it enters a dormant state in the body.

Two recent studies highlight novel ways to combat pattern hair loss in men and women using small molecules such as JAK inhibitors that reawaken dormant hair follicles, as well as stem cell therapies aimed at growing new follicles.

In the first study, researchers led by Angela Christiano, Ph.D., the Richard & Mildred Rhodebeck Professor of Dermatology at Columbia University Vagelos College of Physicians and Surgeons, discovered previously unknown cells that keep mouse hair follicles in a resting state and show that inhibiting the activity of these cells can reawaken dormant follicles.

In a second study, Christiano’s team created a way to grow human hair in a dish, which could open up hair restoration surgery to more people, including women, and improve the way pharmaceutical companies search for new hair-growth drugs.
