AI Article Synopsis
- * A study of Egyptian fruit bats revealed that their home range decreased during spring when food was scarce, leading to changes in their social space-sharing networks.
- * When food was abundant, bats formed less-connected networks and more closely related individuals shared foraging sites, indicating strong communal knowledge of food distribution patterns.
Article Abstract
Animals are faced with a range of ecological constraints that shape their behavioural decisions. Habitat features that affect resource abundance will also have an impact, especially as regards spatial distribution, which will in turn affect associations between the animals. Here we utilised a network approach, using spatial and genetic data, to describe patterns in use of space (foraging sites) by free-ranging Egyptian fruit bats (Rousettus aegyptiacus) at the Dakhla Oasis in Egypt. We observed a decrease in home range size during spring, when food availability was lowest, which was reflected by differences in space sharing networks. Our data showed that when food was abundant, space sharing networks were less connected and more related individuals shared more foraging sites. In comparison, when food was scarce the bats had few possibilities to decide where and with whom to forage. Overall, both networks had high mean degree, suggesting communal knowledge of predictable food distribution.

Article Synopsis
- Bats are considered the primary hosts for many coronaviruses, particularly Betacoronaviruses, which can cause severe respiratory diseases in humans.
- Research showed that Egyptian fruit bats were more susceptible to respiratory infections (like SARS-CoV-2) compared to oral infections, with significant differences in virus shedding and immune response.
- The study suggests that SARS-CoV-2 is likely inactivated in the bats' stomachs, making oral infections less effective, highlighting the unique pathology of coronavirus infections in bats.

Background: N6-methyladenosine (m6A) is an abundant RNA epitranscriptomic modification in eukaryotes. The m6A machinery includes cellular writer, eraser and reader proteins that regulate m6A. () (the Australian black flying fox) and () (the Egyptian fruit bat) are bats associated with several viral zoonoses yet neglected in the field of m6A epigenetics studies.

Culex pipiens mosquitoes are the primary vector of the West Nile virus worldwide and have a wide distribution. To avoid the development of resistance in insect pests to conventional synthetic pesticides, there have been many attempts to study botanical pesticides. The increasing resistance of insect pests to synthetic pesticides is a threat to the diversity of ecosystems, which makes the study of botanical pesticides all the more important.

Cancer progression is primarily driven by the uncontrolled activation of cellular signaling pathways, with the PI3K/Akt/mTOR (PAMT) pathway playing a central role. This pathway significantly contributes to the proliferation and survival of cancer cells, and its hyperactivity is a major challenge in managing several types of malignancies. This article delves into the promising potential of carotenoids, natural pigments found in abundance in fruits and vegetables, as a novel therapeutic strategy for cancer treatment.
