A new longitudinal study examined whether the Ferguson Effect was real. The study, of law enforcement officers before and after Ferguson, found little support for the concept, though it did identify a reduction in officers' job satisfaction and an increase in their cynicism.
Those who consume alcohol and drive are often subjected to roadside stops, breathalyzer tests and stiff penalties if their blood alcohol content exceeds certain limits. Currently, no such test exists for cannabis intoxication, although the substance can impair driving. Now, scientists report a convenient saliva test for cannabis levels that might someday be used at roadside stops. The researchers will present their results today at the American Chemical Society Spring 2020 National Meeting & Exposition.
Spilled coffee forms a ring as the liquid evaporates, depositing solids along the edge of the puddle. This 'coffee ring effect' has fascinated scientists for decades, but now a team says they have uncovered the mechanism behind an even more striking, web-like pattern that forms when drops of American whiskey dry up. The results, reported in ACS Nano, suggest that these distinctive 'whiskey webs' could someday be used to identify counterfeit spirits.
Maggots on a dead body or wound can help pinpoint when a person or animal died, or when maltreatment began in elder, child care or animal neglect cases. However, the current process for making this determination is time consuming and resource intensive. It also relies on species assessment by trained entomologists. Now, researchers report in ACS' Analytical Chemistry the development of a molecular maggot analysis method that's quick, easy and less subjective.
Tanker traffic through the Strait of Hormuz declines for up to two years after a piracy attack, a new Duke University study finds, but the adverse effects of the slowdown affects some Persian Gulf countries more than others. Large exporters of crude oil, like Saudi Arabia, see little long-term impact, while smaller exporters, like Bahrain and Kuwait, can suffer disproportionate losses.
Nearly 94% of defendants in Cuyahoga County drug court have been exposed to trauma and many suffer from symptoms of post-traumatic stress disorder (PTSD), according to a new Case Western Reserve University study.
Indigenous historian and York University professor Jesse Thistle and Dr. Janet Smylie, a Métis family physician and research chair at Unity Health Toronto and the University of Toronto, who are leading the development of a separate guideline specifically to address Indigenous homelessness, co-authored a related commentary in CMAJ.
Imagine purchasing products from your local grocer, only to find out that those products are comprised of critically endangered species! That's what a team from the University of Hong Kong, Division of Ecology and Biodiversity has recently discovered on Hong Kong supermarket shelves. A team led by Dr David Baker from the University's Conservation Forensics laboratory, has recently published the results from an investigation into European eel products on sale in Hong Kong supermarkets.
Researchers developed a new method of analyzing travel survey data to show that the rates of households in the Kumamoto, Japan metropolitan area with everyone out-of-home has increased from 41.3% in 1984 to 51.5% in 2012. This increase partly explains the recent rise in failed parcel redeliveries. The researchers believe their work can be used to reduce redeliveries, develop efficient at-home interview survey methods, and for crime prevention such as burglary countermeasures.
Some states have enacted laws restricting opioid prescribing for the treatment of acute pain and this research letter assess the outcomes associated with Florida's restriction law.
