The study, "Risks to Unique Dialects of Birdsong: The Case of Chaffinch (Fringilla coelebs) Song Dialects in Southern and Eastern Ukraine During the Russia–Ukraine War," was carried out by Eugenia Yablonovska-Grishchenko and Vitaly Grishchenko in Biosphere: A Scientific Journal.

A new study from Ukraine has used satellite imagery to assess the wartime destruction of forests that host distinct regional song dialects of the Common Chaffinch, finding that while most study sites remain intact, nearly a third have been damaged or destroyed by combat, and that the type of forest determines how much is lost when the fighting reaches it.

Black people in Canada have an increased risk of severe maternal morbidity (SMM) — serious complications that can occur during pregnancy, labour or delivery, and postpartum — compared with White people, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.252020.

Several Canadian jurisdictions are moving toward ending the twice-yearly clock change, but a new analysis published in CMAJ (Canadian Medical Association Journal)  https://www.cmaj.ca/lookup/doi/10.1503/cmaj.261089 argues that eliminating the clock change is only half the decision: governments must also decide whether to adopt permanent standard time or permanent daylight saving time. Both choices have trade-offs. Permanent daylight saving time keeps evenings lighter, which may support recreation, social activity, commuting, and some economic activity.

Three years after October 7, the 2026 Hebrew University-European Forum Barometer reveals a significant shift in how Israelis view themselves, their security, and their relationship with Europe. Jewish Israelis report a strengthened sense of Israeli identity, while many Israelis increasingly see the country as more Middle Eastern than European. The survey also finds that Israelis overwhelmingly view Israel as safer for Jews than Europe, even as European respondents are far more divided. At the same time, Israelis express growing skepticism toward the European Union, continue to see Germany and Hungary as among Israel’s closest friends in Europe, and identify France and Spain as the countries they perceive as most antisemitic.

The way digital technologies are currently built and governed creates real risks to health worldwide, alongside genuine benefits, according to a new three paper Series authored by 13 global experts, published in The Lancet. The authors call for coordinated governance of digital systems, with the health and online safety of children and young people made an immediate global policy priority.

Artificial Intelligence (AI) can predict judicial decisions, but can it explain how they are legally jusitified, and can judges trust it? A Perspective in National Science Review argues that legal computing requires higher interpretability and reliability, and judicial values should be embedded into model and algorithm design. It outlines a value-guided framework within a “society–law–ethics–algorithms–data” system and identifies three scenario-specific applications: legislation, feedback-validated enforcement and trustworthy, human-centered adjudication. The Perspective further suggests that combining empirical learning with formal reasoning may offer a particularly promising path forward.
