Contrary to some claims, people in the U.S may not be substituting cannabis for opioids, according to new research at Columbia University Mailman School of Public Health. The study examined the direction and strength of association between cannabis and opioid use over 90 consecutive days among adults who used non-medical opioids. The findings showed that opioid use was at least as prevalent on days when cannabis was used as on days when it was not, and that this was irrespective whether participants were experiencing pain or not. The study, published in the scientific journal Addiction, is among the first to test opioid substitution directly.
The study, which compared the probability of non-medical opioid use on days when cannabis was used with days when cannabis was not used, included 13,271 days of observation among 211 participants from the greater New York area. The participants were predominantly male, urban, unemployed, unmarried,

Servi will act as a waiter, with the ability to carry food and drinks from the kitchen to tables. It will use 3D cameras and LIDAR technology to navigate around tables and customers, the same technology used by autonomous vehicles. It officially launches in Japan in January but has already been tested by some restaurants

New dedicated hubs for Deaf children are needed around the country to provide new social spaces, education and support, an expert has said.
Special schools for Deaf children have had an important role in the Deaf community, acting as places people can meet and learn BSL together. But the move to inclusive education and new technology such as cochlear implants means most children with hearing loss are now educated in mainstream schools.
Deaf education should be remodelled to replace the role previously provided by specialist schools which have closed, Dr Hannah Anglin-Jaffe argues in a study in the British Education Research Journal.
Dr Anglin-Jaffe proposes Deaf education and support could be run in the same way as existing community provision in schools and other social spaces such as libraries or community centres. These hubs could act as a new iteration of the special school for the Deaf and host
Starting next month, all new source code repositories created on GitHub will be named “main” instead of “master” as part of the company’s effort to remove unnecessary references to slavery and replace them with more inclusive terms.
GitHub repositories are where users and companies store and synchronize their source code projects.
By default, GitHub uses the term “master” for the primary version of a source code repository. Developers make copies of the “master” on their computers into which they add their own code, and then merge the changes back into the “master” repo.
“On October 1, 2020, any new repositories you create will use main as the default branch, instead of master,” the company said.
Existing repositories that have “master” set as the default branch will be left as is.
“For existing repositories, renaming the default branch today causes a
