Smiling underwater: Exploring playful signals and rapid mimicry in bottlenose dolphins.

Play is a widespread behavior present in phylogenetically distant taxa that, in its social form, relies on complex communication. Playful communication has been largely neglected in marine mammals. We focus on playful visual communication in bottlenose dolphins.

Frictional Contact of Soft Polymeric Shells.

The classical Hertzian contact model establishes a monotonic correlation between contact force and area. Here, we showed that the interplay between local friction and structural instability can deliberately lead to unconventional contact behavior when a soft elastic shell comes into contact with a flat surface. The deviation from Hertzian solution first arises from bending within the contact area, followed by the second transition induced by buckling, resulting in a notable decrease in the contact area despite increased contact force.

Secukinumab and Dead Sea Climatotherapy Impact Resolved Psoriasis Skin Differently Potentially Affecting Disease Memory.

Secukinumab and Dead Sea treatment result in clear skin for many psoriasis patients, through distinct mechanisms. However, recurrence in the same areas after treatments suggests the existence of a molecular scar. We aimed to compare the molecular and genetic differences in psoriasis patients who achieved complete response from secukinumab and Dead Sea climatotherapy treatments.

Development and application of a whole genome amplicon sequencing method for infectious salmon anemia virus (ISAV).

Infectious salmon anemia (ISA) is an infectious disease primarily affecting farmed Atlantic salmon, , which is caused by the ISA virus (ISAV). ISAV belongs to the family. The disease is a serious condition resulting in reduced fish welfare and high mortality.
