The MAJIS instrument aboard the European Space Agency’s JUICE spacecraft performed well during its August 2024 Earth-Moon gravitational assist. Tests supported its updated wavelength calibration and showed that its brightness measurements were close to expected values, strengthening confidence in future observations around Jupiter.
Two studies of active gamers suggest that returning smoothly from gameplay to daily life is linked to better mood, vitality and life satisfaction, and to fewer symptoms of gaming disorder. The findings point to a way of studying escapism that looks beyond why people play to what happens when they stop.
This review examined national hepatitis B and C testing and treatment policies in eight high-burden countries in the WHO European Region. It found that guidelines and decentralized services were common, but access to testing, affordable medicines and treatment in harm-reduction settings remained uneven. The survey describes health-system practices; it did not measure treatment outcomes in individual patients.
Lepcha farmers in Sikkim use flowering plants, bird behaviour, insect activity, frog calls, fish movements and other ecological signs to track seasonal changes. A study documents a 12-month traditional calendar linked to sowing, harvesting, gathering and other livelihood activities.
An exploratory survey of 63 people in the United States identified six kinds of challenges reported by people in polyamorous relationships. They included familiar relationship struggles, difficulties linked to having multiple partners, and pressure from stigma and expectations that relationships should be monogamous.
This human-health review examined cardiovascular and autonomic outcomes in children after SARS-CoV-2 infection or multisystem inflammatory syndrome in children (MIS-C). It reports that obvious heart dysfunction usually improved, while some studies found persistent changes on more sensitive tests and symptoms linked with autonomic dysfunction. The importance of these findings for children’s long-term health remains uncertain.
The dry-season shrub Wigandia urens can produce seeds through autonomous self-pollination when pollinators are less active. Researchers found that animal pollinators still contributed substantially to seed production, giving the plant both reproductive backup and opportunities for cross-pollination.
In a national US study, adolescents and young adults exposed to a suicide attempt within their social networks had higher odds of a later suicide attempt and higher depressive symptoms over time. The exposure was not linked to the onset of suicidal thoughts.
Researchers developed an attack that generates backdoor triggers tailored to a shared AI model in federated learning. In experiments across multiple datasets, it improved the attack success rate by 60.95–80.19% over average baseline performance without increasing the malicious updates sent to the system.
A study of 984 U.S. adults found that fears about economic insecurity and technology were each associated with greater support for political violence. The link with economic fears appeared among people with low and middle socioeconomic status, while technology-related fears were linked to support among people with low and high socioeconomic status.
Researchers have described a new freshwater amoeba species from Budamu Stream near Cape Coast, Ghana. Their analysis also identified an additional lineage and up to seven possible Mayorella groups, many made up of unnamed or environmental sequences.
Researchers reviewed 16 randomized trials involving 5,668 people with vascular dementia. Galantamine and memantine were linked with small changes on some cognitive test scores over the short term, but consistent benefits for daily functioning, overall condition, or behavior were not established.
A systematic review of 18 quantitative studies found that responsiveness was the governance practice most consistently associated with public trust in local governments. Transparency and formal accountability had more conditional relationships, with service delivery, perceived performance and effectiveness helping shape how people judged local authorities.
Researchers combined results from seven randomized trials involving 1,334 people with previously untreated peripheral T-cell lymphoma, a rare blood cancer. The analysis found that some regimens produced higher response or disease-control rates than CHOP, but it found no significant differences in overall survival or progression-free survival. Risks of particular blood-related side effects varied among regimens.
A systematic review and meta-analysis examined changes in eye-pressure readings and corneal measurements after small-incision lenticule extraction, or SMILE, a procedure used for nearsightedness and some astigmatism. Across 17 observational studies involving 1,177 eyes, pressure readings were lower after surgery with several measurement devices, but the review cannot establish how much of this reflected a change in true eye pressure rather than measurement effects.
