Among young adults who frequently use cannabis, drinking alcohol is linked to intensified cannabis cravings in men and reduced cannabis cravings in women, a novel study suggests. The findings potentially illuminate mechanisms driving the combined use of the two substances and could inform sex-specific approaches to preventing or addressing the resulting harms. Young adults commonly use alcohol and cannabis together (i.e., co-use), and people who use both substances experience more negative consequences—including worse outcomes for alcohol use disorder treatment—than those who use one or the other. Co-use may be partially driven “cross-substance-induced” craving, in which the repeated co-use of two substances prompts one to become a trigger for the other. Research on this effect involving alcohol and cannabis—previously limited to laboratory testing and remote monitoring—has hinted at sex differences in these effects. For the study in Alcohol: Clinical Experimental Research, investigato

Yes, men run faster than women, but over shorter distances — not by much
Conventional wisdom holds that men run 10-12 percent faster than women regardless of the distance raced. But new research suggests that the between-sex performance gap is much narrower at shorter sprint distances.
Rare Human Gene Variant in ADHD, Autism Exposes Fundamental Sex Differences
Key differences in male and female mice brains provide new insights into how sex determines the mechanisms by which distinct synapses monitor and regulate dopamine signaling. The impact of sex differences is particularly pronounced when the mice express a human genetic variant found in boys with either ADHD or autism. Behavioral generalizations across the sexes may limit diagnosis of mental illness, especially if one sex translates alterations into outward signs such as hyperactivity and aggression vs. more internal manifestations such as learning, memory and mood, even when the same molecular pathology is at work.
Drugs Effects of Ketamine in Mice can Depend on the Sex of the Human Experimenter

When it Comes to Preventing Alzheimer’s, Women and Men are Not Created Equal
A study is the first to examine if sex significantly affects cognitive outcomes in people who follow individually-tailored, multi-domain clinical interventions. The study also determined whether change in risk of developing cardiovascular disease (CVD) and Alzheimer’s disease (AD), along with blood markers of AD risk, also were affected by sex. Results showed that while care in an Alzheimer’s Prevention Clinic setting is equally effective at improving cognitive function in both women and men, the personally-tailored interventions used by the researchers led to greater improvements in women compared to men across AD and CVD disease risk scales, as well blood biomarkers of risk such as blood sugar, LDL cholesterol, and the diabetes test HbA1C. Findings are important because women are disproportionately affected by AD and population-attributable risk models suggest that managing risk factors can prevent up to one-third of dementia cases.

Women: Lower-fat Diet Key to Liver Health Following Weight-loss Surgery

When seeing is believing
Being able to vividly imagine graduating college predicts grade point average and whether a student continues in a STEM or business degree program, according to a longitudinal study from Arizona State University. The study also found sex differences between how men and women visualized their post-graduation goals: Men increased the level of detail, but women remained stagnant. These findings could have implications for why women are underrepresented in STEM and business careers.
