The similar to 790 ka Australasian (micro)tektite strewn field is one of the most recent and best-known examples of impact ejecta emplacement as the result of a large-scale cratering event across a considerable part of Earth's surface (>10% in area). The Australasian strewn field is characterized by a tri-lobe pattern consisting of a large central distribution lobe, and two smaller side lobes extending to the west and east. Here, we report on ...

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘high risk plants, plant products and other objects’. Taking into account the available scientific information, including the technical information provided by the applicant country, this Scientific Opinion covers the plant health risks posed by the following ...

Forest insects are emerging in large extension in response to ongoing climatic changes, penetrating geographic barriers, utilizing novel hosts, and influencing many hectares of conifer forests worldwide. Current management strategies have been unable to keep pace with forest insect population outbreaks, and therefore novel and aggressive management strategies are urgently required to manage forest insects. RNA interference (RNAi), a Noble ...

In the Arusha volcanic region in northern Tanzania, within the eastern branch of the East African Rift System, water shortage is common and much of the surface water and groundwater contain fluoride (F⁻) concentration above the WHO limit (1.5 mg/L) recommended for drinking water. The groundwater is the main source of drinking water in the area. Prolonged intake of this high F⁻ water has caused dental and skeletal fluorosis among the local ...

Recent genome analysis of Erwinia amylovora, the causal agent of fire blight disease on Rosaceae, has shown that the chromosome is highly conserved among strains and that plasmids are the principal source of genomic diversity. A new circular plasmid, pEA68, was found in E. amylovora strain 692 (LMG 28361), isolated in Poland from Sorbus (mountain ash) with fire blight symptoms. Annotation of the 68,763-bp IncFIIa-type plasmid revealed that it ...

Soils along a toposequence (1500-2260 m) on the southern slope of the volcanic Bambouto Mountains in western Cameroon were investigated to elucidate the occurrence and development of andic properties at high altitude ( > 1800 m) in the study area. The surface layer that has these properties has in the past been interpreted as a weathered volcanic ash layer, overlying ferrallitic soils that developed from lava flow deposits and derived ...

The jujube honey from the Moroccan Middle Atlas area is thoroughly described in this study, which takes into account melissopalynological, physicochemical, antioxidant, mineral, and phytochemical characteristics. Twelve samples of jujube honey underwent in-depth analyses between 2019 and 2021. The honey's unifloral origin was confirmed by pollen analysis, which revealed that Ziziphus lotus pollen predominated along with pollen from 21 other ...

Dryopteris filix-mas (hereafter D. filix-mas), a wild leafy vegetable, has gained popularity among high mountain residents in the Hindukush-Himalaya region due to its exceptional nutritional profile, and their commercial cultivation also offers viable income alternatives. Nevertheless, besides phytochemicals with medicinal applications, ecological factors strongly affect their mineral contents and nutritional composition. Despite this, little ...

In this article I explore how local tropes of hole and suture tell us something about the changes that have taken place in how urbanity is imagined and lived in the Democratic Republic of Congo today. More than ever, there is the need to be attentive to new concepts that arise from the ground up to open up or rescale our thinking about a city such as Kinshasa in order to decenter and reframe urban theory more generally. The hole (and its ...
