The hatching mechanism of 130-million-year-old insects: an association of neonates, egg shells and egg bursters in Lebanese amber [PDF]

open access: yes, 2018
Hatching is a pivotal moment in the life of most animals. Diverse chemical, behavioural and mechanical methods have evolved in metazoans to break the egg membranes.

Ageing as “early‐life inertia”: Disentangling life‐history trade‐offs along a lifetime of an individual [PDF]

open access: yes, 2021
The theory that ageing evolves because of competitive resource allocation between the soma and the germline has been challenged by studies showing that somatic maintenance can be improved without impairing reproduction.

The kSORT assay to detect renal transplant patients at high risk for acute rejection: results of the multicenter AART study [PDF]

open access: yes, 2018
Background: Development of noninvasive molecular assays to improve disease diagnosis and patient monitoring is a critical need. In renal transplantation, acute rejection (AR) increases the risk for chronic graft injury and failure. Noninvasive diagnostic
