A comprehensive genetic resource of rat-infecting malaria parasites has been published, providing insights into the evolution, virulence, and transmissibility of the disease. The study reveals diverse genetic and phenotypic variations between subspecies, which may aid in understanding malaria parasite gene functions.
Researchers at the Weizmann Institute of Science used fruit bats to study navigation in an experimental setup that emulates their natural environment. They found that a single neuron can represent multiple place fields and that the size of each field changes according to location, resolving the discrepancy between traditional models.
An Indigenous Māori framework offers a new perspective on managing and conserving Antarctica, focusing on responsibilities rather than rights. This approach acknowledges the intrinsic link between human well-being and the environment, promoting reciprocal and sustainable relationships with the continent.
Researchers have discovered significant smoke aerosols in pre-industrial Southern Hemisphere ice core samples, revealing a much fierier past than previously thought. This finding helps to refine climate predictions by accounting for the cooling effect of smoke particles, which may have been underestimated in current models.
