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鈥攊ncluding worse outcomes for alcohol use disorder treatment鈥攖han those who use one or the other.

Researchers at the Facility for Rare Isotope Beams made a high-precision mass measurement of aluminum-22, reaching the 鈥減roton dripline鈥� of the nuclear chart. The project found that aluminum-22 formed a proton halo, where the last proton added is only loosely bound to the nucleus. This measurement helps scientists determine how tightly bound the atomic nuclei are as they get closer to the dripline.
