However, the low quality of evidence makes it unclear whether there is a causal relationship between cannabis and subsequent opioid use.
Researchers found that larger male mosquitofish are preferred by females and produce more sperm. They also excel at driving off rivals and using forced mating strategies due to their small size and agility. The study analyzed 36 studies and provided new insights into the relationship between body size and reproductive success in fish.

A systematic review and meta-analysis found that the FDA approved drugs and devices based on nonrandomized clinical trials (10%), with estimated treatment effects higher for these approvals. The study's findings suggest that no clear threshold of treatment effect exists, which may lead to more frequent RCTs in the future.
A study published in JAMA Psychiatry found that differences between people with autism and the general population are shrinking over time. The researchers believe that changes in diagnostic criteria, such as a shift from lack of interest in others to simply having fewer friends, are contributing to the apparent increase in prevalence
