Preclinical study links human gene variant to THC reward in adolescent females

A common variation in a human gene that affects the brain's reward processing circuit increases vulnerability to the rewarding effects of the main psychoactive ingredient of cannabis in adolescent females, but not males, according to preclinical research by Weill Cornell Medicine investigators. As adolescence represents a highly sensitive period of brain development with the highest risk for initiating cannabis use, these findings in mice have important implications for understanding the influence of genetics on cannabis dependence in humans.

Researchers develop 'multitasking' AI tool to extract cancer data in record time

As the second-leading cause of death in the United States, cancer is a public health crisis that afflicts nearly one in two people during their lifetime. Cancer is also an oppressively complex disease. Hundreds of cancer types affecting more than 70 organs have been recorded in the nation's cancer registries—databases of information about individual cancer cases that provide vital statistics to doctors, researchers, and policymakers.

Researchers link quartz microbalance measurements to international measurement system

Researchers at the National Institute of Standards and Technology (NIST) have found a way to link measurements made by a device integral to microchip fabrication and other industries directly to the recently redefined International System of Units (SI, the modern metric system). That traceability can greatly increase users' confidence in their measurements because the SI is now based entirely on fundamental constants of nature.

How bird flocks with multiple species behave like K-pop groups

Birds of a feather don't always flock together: Peer into a forest canopy, and you will likely spot multiple bird species flying and feeding together, a phenomenon most spectacular in the Amazon where 50 species may travel as a unit. But are birds in these mixed flocks cooperating with one another or competing?

MAiD is not driven by socioeconomic vulnerability or poor access to palliative care

A new study of people who received medical assistance in dying (MAiD) in Ontario found that about three-quarters were cared for by palliative care practitioners at the time of their request for MAiD, and MAiD recipients were younger, wealthier and more likely to be married than the general population at time of death. These findings dispel concerns that MAiD requests are driven by lack of access to palliative care services or by socioeconomic vulnerabilities.The article is published in CMAJ (Canadian Medical Association Journal) along with a related editorial.
