One-pot method for recombinant geranylgeranylated protein production

Patent published on the 2026-06-11 in WO under Ref WO2026122736 by MOZHDEHI DAVOUD [US] (Alam Md Mahbubul [us], Mozhdehi Davoud [us])

Abstract: A method for the one-pot production of geranylgeranylated proteins in Escherichia coli. E. coli is engineered to express geranylgeranyl pyrophosphate synthase, an enzyme that catalyzes production of geranylgeranyl pyrophosphate, and a target protein. By co-expressing GGS with a geranylgeranyltransferase, efficient geranylgeranylation of model protein substrates was achieved, including intrinsically disordered elastin-like polypeptides (ELPs) and the globular protein mCherry. This modification af[...]


Our summary: A one-pot method for producing geranylgeranylated proteins in E. coli was developed. The method involves co-expressing geranylgeranyl pyrophosphate synthase and geranylgeranyltransferase for efficient modification of target proteins. This approach is scalable and cost-effective, enhancing studies on lipid-modified proteins for drug delivery and tissue engineering.

Implant for competing blood vessel to promote fistula maturation and method thereof

Patent published on the 2026-06-11 in WO under Ref WO2026120542 by COVIDIEN LP [US] (Mcconnell Kevin [us], Bayon Yves [us])

Abstract: An implant is used in a competing vein of a primary vein of an arteriovenous (AV) fistula to promote maturation of the AV fistula. The implant includes a blood flow restrictor configured to be delivered to a selected location in the competing vein and engage a wall of the competing vein at the selected location. The blood flow restrictor enables blood in the competing vein to flow therethrough, while reducing a volumetric blood flow rate as the blood flows therethrough. The blood flow restrictor[...]


Our summary: An implant is used in a competing vein of an AV fistula to enhance maturation. It includes a blood flow restrictor that reduces blood flow while allowing passage. The restrictor biodegrades over time, increasing blood flow as it degrades.

Kovacs-like memory effect in strain stiffening collagen networks

Published on 2026-06-10 by Abhishek Ghadai, Maitri Mandal and Sayantan Majumdar @IOP SCIENCE

Abstract: Materials driven far from equilibrium can encode memories of past deformations through long-lived structural reorganizations. Such memory effects-reflecting parameters such as deformation direction, magnitude, and duration have been widely explored in soft amorphous solids. Here, we report a Kovacs-like memory effect manifested as a non-monotonic stress relaxation in vitro biopolymer networks formed by type-I collagen, an essential component of the mammalian extracellular matrix. Using shear rhe[...]


Our summary: The study identifies a Kovacs-like memory effect in type-I collagen networks. This effect is linked to non-monotonic stress relaxation during nonlinear strain-stiffening. The findings reveal a correlation between memory response and negative normal stresses in biopolymer networks.

an aerial view of greening Svalbard

Published on 2026-05-21 by Alice Drinkwater @NATURE

Abstract: Communications Earth & Environment, Published online: 21 May 2026; doi:10.1038/s43247-026-03543-7The twentieth century saw a rapid expansion in Arctic tundra vegetation. Dr Ingrosso and colleagues examined these changes over time by using plant-derived biomarkers (biopolymers from plant leaves and cell walls) from a sediment core in Svalbard. They found that Svalbard’s greening was driven by a decline of summer sea ice and glacier retreat, and that the expansion was associated with vascula[...]


Our summary: Researchers studied sediment core biomarkers to assess greening in Svalbard. The findings link vegetation expansion to reduced summer sea ice and glacier retreat. This greening trend indicates potential future shifts in the Arctic environment due to climate change.
