Prepared Core Technologies, often considered a hallmark of the Middle Paleolithic Mousterian, have recently been observed, to some extent, in many late Lower Paleolithic Acheulian sites. This may indicate a Lower Paleolithic origin of the Levallois method, although the circumstances leading to its emergence, spread and assimilation are still debated. We aim at contributing towards this intriguing issue by studying patterns of flint procurement and exploitation at Late Acheulian Jaljulia (Israel; ∼500–300 kya). We classified artifacts into flint types, using four samples: a general sample, bifaces, “regular” cores with one/two striking platforms, and prepared cores, divided into proto-Levallois, prepared (general) and discoid cores. A geologic survey located potential flint sources, and a petrographic analysis was used to assign flint types to sources. Our results show that while local Turonian flint of the Bi’na Formation dominates the general sample, selectivity in using specific flint types was observed, including among local materials. While brecciated flint types are especially common among handaxes and discoid cores, among proto-Levallois and prepared cores (general), fine-textured homogenous flint types are more common, suggesting that such flint types are better-suited when improved control over the end-product was desired. Based on our results, and following previous suggestions, we support the hypothesis that prepared core technologies in the Levant did not originate from one single technological trajectory. We support the idea that the production of predetermined blanks was based on knowledge gathered from several technological trajectories, including mainly biface shaping and the production of flakes from regular cores. This novel method was most likely transmitted time and again between individuals, gradually adjusting it to produce improved end-products. We see these conclusions as additional support for the view of prepared core technologies at the Late Acheulian as a demonstration of cumulative culture, and the existence of high-fidelity social learning mechanisms in practice already during the late Lower Paleolithic of the Levant.

Background: Armed conflicts are likely to have implications for the welfare and safety of children, potentially leading to increased rates of unintentional childhood injuries. Methods: We examine data from Israel concerning the relationship between emergencies and childhood mortality due to unintentional injuries using the media-based database of Beterem Safe Kids Israel to analyse seven events: 2008 Gaza War, 2014 Gaza War, first COVID-19 Lockdown, second COVID-19 Lockdown (September 2020), third COVID-19 Lockdown (December 2020), 2021 Israel–Palestine crisis and 2023 Israel–Gaza War. These events are categorised into Emergency Periods (EPs) and Emergency Routine Periods (periods during which an emergency extends and normalises into a stable routine; ERPs). For each EP we selected a comparable Routine Period (RP). Results: Unintentional childhood mortality rates are lower during EPs, compared with RPs. Conversely, there is an increase in unintentional mortality rates during ERPs. EPs and ERPs occurring during armed conflicts exhibit higher unintentional mortality rates compared with health-related EPs and ERPs. Furthermore, military-related ERPs show higher unintentional mortality rates compared with the corresponding RPs. Unintentional mortality rates are notably higher among Arab children compared with Jewish children, particularly during ERPs. Unintentional childhood mortality also differs as a function of socioeconomic ranking, with widening gaps between municipalities of low socioeconomic ranking and municipalities of medium to high socioeconomic ranking, during EPs and ERPs. Conclusions: We hypothesise that parents’ emotional availability declines during EPs and ERPs associated with military conflicts, coinciding with socioeconomic aspects, impacting families’ well-being and children’s safety.

Background: The increasing use of motorised wheeled vehicles has reshaped urban mobility for children and adolescents, but also poses significant safety risks. This study examines child fatalities from crashes involving motorised two-wheeled vehicles (e-bikes and e-scooters) in Israel, comparing them to non-motorised bicycle and scooter fatalities. We analysed behavioural and demographic risk factors and provided evidence-based policy recommendations. Methods: We analysed fatal childhood incidents (ages 0–17) recorded in Beterem Safe Kids Israel’s media-based database from 2008 and 2024. Mortality rates per 100 000 were calculated, and statistical analyses, including χ ² tests, assessed differences across socioeconomic and age groups. Results: 78 child fatalities were documented; 94.9% were boys, with an average age of 11.5 years. Mortality rates rose by 60.5% after motorised vehicles were introduced in 2016. Arab children were disproportionately affected (χ ² =13.46; p<0.05), particularly in non-motorised vehicle crashes. Lower-income groups had higher fatality rates, while motorised vehicle fatalities were more common in mid-to-high socioeconomic clusters. Conclusions: Despite legislation, gaps in enforcement and public awareness persist. Strengthening helmet laws, enforcing speed limits and promoting safety education are crucial. Culturally and socioeconomically tailored interventions, needs-based budgeting and subsidies for protective gear can further enhance child safety.

We examined lithic artifacts from the late Neanderthal site Sesselfelsgrotte (Bavaria, Germany) in order to evaluate the possibility of fire use and intentional flint heat treatment performed by late Neanderthals. We analyzed 1113 flint pieces from the G-layer complex (~60 to 45 kya; Micoquian) and 946 from the lower-layer complex (~115 to 70 kya; Mousterian). Based on macroscopic traits associated with the exposure of flint to heat and fire, we assigned artifacts to one of three groups: burnt, unburnt, and possibly intentionally heated. Our results show that while both complexes demonstrate the clear presence of fire, fire is more common in the younger G-layer complex. Moreover, possibly intentionally heated pieces are significantly more frequent in the G-layer complex, especially among the tools and specifically among side scrapers, suggesting a link between heat treatment and the production of these tools, most probably due to their functional and cultural significance. We therefore suggest that the flint in the G-layer complex of Sesselfelsgrotte underwent intentional heat treatment. The proportions of burnt flint artifacts in both complexes suggest an intensification in fire use at the site over time, while the appearance of possibly intentionally heated artifacts in the G-layer complex suggests the development of this advanced pyrotechnology by Neanderthals sometime between these two timeframes. Our results are supported by sedimentological and faunal data. We view these results as further indication of the advanced cognitive and technological capabilities of Neanderthals, which did not fall short of those of early modern humans.
