What does the data tell us about trends in workplace homicides?


In the 1990’s and early 2000’s, 65% of workplace homicides occurred during robberies. Now, new research published in Injury Epidemiology, finds that this figure has fallen to 46%, with 54% being attributable to non-robbery events, such as an interpersonal arguments or mass shootings. Mitchell Doucette, lead author of the study, speculates on the causes of this shift towards non-robbery related crimes and argues that prevention measures must also shift accordingly.


Can maternal exposure to carbon black nanoparticles affect male fertility?


Carbon black nanoparticles are manufactured for use in rubber products, as a color pigment in plastics, paint and ink and used to model exposure to air pollution particles. These particles have been shown to have toxic effects and previous mice studies have shown that maternal exposure can affect the sperm count in male offspring. In this Q&A, Dr Karin Sørig Hougaard and PhD student Astrid Skovmand discuss their recently published paper in Particle and Fibre Toxicology which shows that in contrast to previous studies, maternal exposure to carbon black nanoparticles does not affect future (fourth) generations of male mice sperm counts.
