The use of stone tools by macaques in Thailand has reduced the size and population density of coastal shellfish; previously it was thought that tool-assisted overharvesting effects resulted uniquely from human activity.
This comprehensive transcriptomic resource of dormant and replicating malaria liver parasites highlights the dearth of pathways that operate in the hypnozoites and the need to investigate druggability (i.e. selectivity and safety) of core pathways in malaria parasites.
IL-1β release from macrophages might be responsible for the unexplained cone segment loss in retinal degenerative diseases that are associated with subretinal inflammation, such as retinitis pigmentosa or geographic atrophy.
Biochemical and genetic tests have revealed that a liver protein called NTCP is a functional receptor for hepatitis B and D viruses, which should lead to an improved understanding of the infections caused by these viruses and assist the development of new intervention strategies.
A rigorous and transparent evaluation of mesenchymal stem cell therapy for sepsis suggests it may be efficacious, although the strength of these findings is tempered by threats to validity in the studies that were included.
A combination of physiological and perceptual experiments show that the responses of rod photoreceptors inhibit those of cones more than vice versa, and reveal both the site of the retinal interaction and the underlying mechanism.
