The study included completion of an online survey by 27 physicians, who reported working in 15 of 26 provincial correctional facilities for adults in Ontario. This included 10 of the 13 facilities with a population of more than 200. The study identified that about half of the physicians prescribed methadone and half prescribed buprenorphine/naloxone to treat opioid dependence.
Three billion miles away on the farthest known major planet in our solar system, an ominous, dark storm is shrinking out of existence as seen in pictures of Neptune taken by the Hubble Space Telescope. Immense dark storms on Neptune were first discovered in the late 1980s by the Voyager 2 spacecraft. Since then, only Hubble has tracked these elusive features that play a game of peek-a-boo over the years.

With this year’s severe flu season, one statistic is especially chilling. Each year, around 50 percent of all children under 5 years old who die from the flu were previously healthy, according to the Centers for Disease Control and Prevention (CDC). Adults who die from the flu, on the other hand, typically had a medical condition that increased their risk of mortality. A new study published in the Journal of Immunology offers new insights as to why healthy children are much more vulnerable. It also opens new opportunities for treatment.

The added weight, electricity demand and aerodynamic drag of the sensors and computers used in autonomous vehicles are significant contributors to their lifetime energy use and greenhouse gas emissions, according to a new study.
Caring for patients with physical disabilities, particularly spinal cord injury (SCI), is not routinely part of the medical school curriculum. However, 17 percent of Americans are physically disabled, and there are nearly 17,000 new cases of SCI in America each year. Many patients report needing to educate their providers on the basic details of their disabilities. Furthermore, medical students and residents report discomfort caring for patients with disabilities. Researchers developed a curriculum for medical students to address this gap.
In the setting of acute traumatic spinal cord injury (SCI), opioid administration is standard care for pain management. However, animal models of SCI have shown that opioid use in the early phase of SCI is deleterious to future quality of life (QOL), notably pain and motor function (Woller et al.). This study focuses on opioid use in the first few days to weeks following human SCI as it relates to QOL outcomes 1-year post-treatment.
This study aims to develop a mechanical horseback riding simulator for the rehabilitation of children with neurological and musculoskeletal disabilities, focused on improving trunk control in this population.

This study aims to demonstrate a wearable functional electrical stimulation (FES) orthotic provided manual dexterity for object manipulation through a thought-controlled brain-computer interface (BCI).
Individuals with disabilities face barriers to physical activity, recreation, and sport. The goal of this study was to determine whether the perception of these barriers differs among those with and without a disability. Second, it aims to determine if these perceptions change following a community-wide recreational festival (RF) targeting to increase adaptive physical activity, recreation, and sport.
Quantum entanglement is a key feature of a quantum computer. Yet, how can we verify that a quantum computer indeed incorporates a large-scale entanglement? Using conventional methods is hard since they require a large number of repeated measurements. Aleksandra Dimić from the University of Belgrade and Borivoje Dakić from the Austrian Academy of Sciences and the University of Vienna have developed a novel method where in many cases even a single experimental run suffices to prove the presence of entanglement. Their surprising results will be published in the online open access journal npj Quantum Information of the Nature Publishing group.
Hurricanes spawn most of the largest storm surges in the northeastern U.S., right? Wrong, according to a study by Rutgers University–New Brunswick scientists. Extratropical cyclones , including nor’easters and other non-tropical storms, generate most of the large storm surges in the Northeast, according to the study in the Journal of Applied Meteorology and Climatology. They include a freak November 1950 storm and devastating nor’easters in March 1962 and December 1992.
