Boolean Logic‐Based Control Over Recombinant Protein Biomaterial Degradability and Therapeutic Delivery

open access: yesAdvanced Materials, EarlyView.
Fully recombinant protein‐based biomaterials execute complex Boolean logic for user‐programmable material degradation and concomitant therapeutic cargo release. Biologics, such as growth factors, can be incorporated within the crosslinkers as “drugamers”, while encapsulated cells can be released according to nested YES/OR/AND‐type logical operations ...

“Upside down” – a strange way of wearing pendants

open access: yesActa Academiae Artium Vilnensis
This paper examines the phenomenon of “inverted” pendants found in archaeological sites in the Baltic region, particularly from the Stone Age. These anthropomorphic and zoomorphic pendants – depicting human heads, birds, snakes, and elks – were often
