About the Author

Kirstin Hendrickson, Ph.D., is a science journalist and faculty in the Department of Chemistry and Biochemistry at Arizona State University. She has a PhD in Chemistry, and studied mechanisms of damage to DNA during her graduate career. Kirstin also holds degrees in Zoology and Psychology. Currently, both in her teaching and in her writing, she’s interested in methods of communicating about science, and in the reciprocal relationship between science and society. She has written a textbook called Chemistry In The World, which focuses on the ways in which chemistry affects everyday life, and the ways in which humans affect each other and the environment through chemistry.

Good Bacteria Associated with Acne-free Skin

Researchers from the University of California, Los Angeles (UCLA), Washington University in St. Louis and the Los Angeles Biomedical Research Institute have discovered that acne bacteria, which thrive in the oily pores of skin, consist of “bad” strains associated with pimples and “good” strains that may protect the skin and keep it healthy. The finding may help dermatologists develop new, strain-specific treatments for acne. The research is published in the Journal of Investigative Dermatology.

New Medical Specialty Proposed for Combined Depression and Heart Disease

New research suggests that there is a strong link between depression and heart disease. Angelos Halaris, M.D., Ph.D., a psychiatrist at the Loyola University Medical Center, is so impressed by the strength of the correlation that he proposes a new medical subspecialty specifically to study and treat combined depression/heart disease patients. The new subspecialty, “Psychocardiology,” would be for the purpose of increasing physician and patient awareness of the strong link between the two disease processes, and would also increase the likelihood that patients with one of the two diseases — who would therefore be at risk of developing the other — would receive appropriate monitoring.

Study Suggests Light-to-Moderate Drinking During Pregnancy Is Ok

A series of research articles in the British Journal of Obstetrics and Gynecology suggest that light-to-moderate drinking during pregnancy (up to 8 drinks per week) does not affect IQ [1], intelligence, attention, and executive function [2], selective and sustained attention [3], or general intelligence [4] in 5-year-old children.

Coffee May Mitigate Risk Of Heart Failure

Good news for those who love their daily coffee (or two); a new meta-analysis (study of studies) published in the journal Circulation: Heart Failure suggests that moderate coffee consumption reduces the risk of heart failure [1].

New Study Suggests Low-fat Diets Aren’t Effective

With Americans becoming increasingly overweight each year, weight loss is big business. This paves the way for any number of diet books and fads. Some of these are based upon sound scientific principles, while others may not work at all, or may result in a modest weight loss followed by rebound weight gain.

A preliminary scientific study — one neither large enough nor strong enough to be considered conclusive at this point — suggests that low-fat diets may be less effective than other weight-loss strategies from a metabolic perspective [1].
