Retrotransposon Expression Is Upregulated in Adulthood and Suppressed during Regeneration of the Limb in the Axolotl (Ambystoma mexicanum)

open access: yesAdvanced Biology, EarlyView.
The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...

Using a Supramolecular Approach to Engineer Modular Hydrogel Platforms for Culturing Protoplasts – from General Tissue Engineering to Cellular Agriculture

open access: yesAdvanced Biology, EarlyView.
Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular

Haeckel's hierarchies [PDF]

open access: yesNature, 1998
The now-familiar concept of drawing lines of descent as trees seems harmless enough. But it led Ernst Haeckel (who bent the evidence to prove his Darwinian theories) into believing in the evolution of a Germanic super-race.

Bridging Nature and Technology: A Perspective on Role of Machine Learning in Bioinspired Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Machine learning (ML) is revolutionizing the development of bioinspired ceramics. This article investigates how ML can be used to design new ceramic materials with exceptional performance, inspired by the structures found in nature. The research highlights how ML can predict material properties, optimize designs, and create advanced models to unlock a ...

Quantification of Basin-Floor Fan Pinchouts: Examples From the Karoo Basin, South Africa

open access: yesFrontiers in Earth Science, 2019
The topography of the seabed (orientation and gradient) and rheology of the flows greatly influences the character of basin-floor turbidity current deposits.

Incentive Hierarchies [PDF]

open access: yesAnnals of Economics and Statistics, 2000
Because much of work incentives are provided through promotions, their effectiveness depends to a large extent on the structure of the organization's hierarchy. Here, we investigate the impact of the incentive motive on the optimal hierarchy using the Auriol-Renault [2000] framework which highlights the role of recognition in the work place.
