As millions of us embark on New Year pledges to eat better, exercise more and learn something new, research published today suggests hobbies could do more than improve your personal life, they could make you better at work. 

 

The study by researchers from the University of East Anglia (UEA) and Erasmus University Rotterdam explored how ‘leisure crafting’ - intentionally shaping your free time through goal setting, learning and connection - does not just boost well-being outside the office but can spill over into creativity, engagement, and meaning at work, especially for older employees. 

After rising for decades in the United States, opioid overdose deaths have been declining dramatically since 2023, with the annual rate of fentanyl overdose deaths dropping by more than a third by the end of 2024. What’s behind this sudden decline? In this Policy Forum, Kasey Vangelov and colleagues evaluate the evidence for an international supply shock in fentanyl in 2023 and conclude that it could be responsible for the steep decline in overdose deaths. Studying the ups and downs of an illegal drug economy is difficult, but the researchers use data from several sources, including a spike in U.S.-based Reddit users’ reports of a fentanyl drought in mid-to-late 2023. Fentanyl seized during this period shows a concurrent decline in purity and seizures themselves fell during the period, despite being an intense focus of law enforcement. In Canada, supply indicators of fentanyl precursors from China declined at the same time. Together, this evidence indicates that supply disruption may be behind the drop off in fentanyl deaths. “The incentive to restore the illicit fentanyl trade will persist as long as there is demand for the drug …” Vangelov et al. write, adding that “…it may be wise to use the current drought as an opportunity to ramp up the prevention and treatment programs that have evidence of decreasing demand.”

Every time we smile, grimace, or flash a quick look of surprise, it feels effortless, but the brain is quietly coordinating an intricate performance. This study shows that facial gestures aren’t controlled by two separate “systems” (one for deliberate expressions and one for emotional ones), as scientists long assumed. Instead, multiple face-control regions in the brain work together, using different kinds of signals: some are fast and shifting, like real-time choreography, while others are steadier, like a held intention. Remarkably, these brain patterns appear before the face even moves, meaning the brain starts preparing a gesture in advance, shaping it not just as a movement, but as a socially meaningful message. That matters because facial expressions are one of our most powerful tools for communication and understanding how the brain builds them helps explain what can go wrong after brain injury or in conditions that affect social signaling, This may eventually guide new ways to restore or interpret facial communication when it’s lost.

A large-scale register-based study conducted at the University of Oulu, Finland, shows that the propensity of top corporate executives to engage in financial misconduct is strongly associated with the financial crime history of their parents, spouses, and their childhood living environment.
