Exercising at least three times a week for six months reduced stress in a group of family caregivers and even appeared to lengthen a small section of their chromosomes that is believed to slow cellular aging, new UBC research has found.

CHICAGO --- "Cigarette" might appear in the term "e-cigarette" but that is as far as their similarities extend, reports a new Northwestern Medicine report published Friday, Sept. 28, in the journal Nicotine & Tobacco Research. Assuming e-cigarettes are equal to cigarettes could lead to misguided research and policy initiatives, the paper says.

NEW YORK, NY--October 1, 2018--FAIR Health has released an online interactive heat map at fairhealth.org/states-by-the-numbers/map showing new findings on opioid abuse and dependence diagnoses and procedures for each of the 50 states and the District of Columbia.

A large study conducted over 42 years in Shanghai -- China's largest city -- indicates that socioeconomic development most likely contributed to lower death rates for most diseases (except for cancer and diabetes, for which death rates increased), likely because of lifestyle factors. The study is published in CMAJ (Canadian Medical Association Journal).

The University of Central Florida is selling Martian dirt, $20 a kilogram plus shipping.

This is not fake news. A team of UCF astrophysicists has developed a scientifically based, standardized method for creating Martian and asteroid soil known as simulants.

Birth order may play a significant role in how children learn about sex, especially for boys, according to a new study published in the journal Sex Education.

Researchers found that first-born children were more likely to report parental involvement in sex education than later-born children, a pattern which was especially pronounced in men.

AMHERST, Mass. - One of the outstanding questions in neurodevelopment research has been identifying how connections in the brain change to improve neural function during childhood and adolescence. Now, results from a study in rats just reported by neuroscientists Heather Richardson, Geng-Lin Li and colleagues at the University of Massachusetts Amherst suggest that as animals transition into adolescence, specific physical changes to axons speed up neural transmission, which may lead to higher cognitive abilities.

UNIVERSITY PARK, Pa. -- Persistent lung inflammation may be one possible explanation for why having asthma during childhood increases your risk for developing anxiety later in life, according to Penn State researchers.

In a study with mice, researchers found that childhood exposure to allergens was linked with persistent lung inflammation. It was also connected to changes in gene expression related to stress and serotonin function.

DETROIT - A research team led by Arun Iyer, Ph.D., assistant professor of pharmaceutical sciences in the Eugene Applebaum College of Pharmacy and Health Sciences at Wayne State University, has developed a nanoplatform technology that works in combination with existing chemotherapeutic drugs that may reverse drug-resistance in renal cell carcinoma.

RIVERSIDE, Calif. - The borderlands between the United States and Mexico are home to numerous Mexican and Central American rural communities, with many members living in poverty and frustrated by limited access to basic resources.
