Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality
Advanced Materials, EarlyView.Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

A Systematic Approach to Analyze T Cell Migration: Application to Mouse Melanoma Tumors
Advanced Therapeutics, EarlyView.The results show that a minimum of two migration speeds can be rigorously identified from the data with cells switching between a fast, persistent migratory state, and a slow, random migration state. These results will help in identifying genetic factors that influence rapid migration, among other applications, such as quality control for CAR‐T cell ...

Connecting innovation and policy to reduce to carbon emissions from manufacturing [PDF]
E3S Web of ConferencesDrawing on qualitative case study data from Scottish distilleries and from UK cement production, this paper explores firmand sector-level responses to the net zero carbon emissions challenge, demonstrating the difference between two pathways: (1 ...

Frontiers in Plant Science, 2022 Geitonogamy is inevitable in hermaphrodite and monecious. Even for self-incompatible species, the negative effects of self-pollen are unavoidable when geitonogamous or self-mating occurs.

Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth [PDF]
, 2005 Background: Callose (β-1,3 glucan) separates developing pollen grains, preventing their underlying walls (exine) from fusing. The pollen tubes that transport sperm to female gametes also contain callose, both in their walls as well as in the plugs that ...

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]
, 2016 PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

Advanced Science, EarlyView.This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.
