Haiyang Wang, Lana Shabala, Meixue Zhou, Sergey Shabala
Background: More than 20% of the world's agricultural land is affected by salinity, resulting in multibillion-dollar penalties and jeopardising food security. While the recent progress in molecular technologies has significantly advanced plant breeding for salinity stress tolerance, accurate plant phenotyping remains a bottleneck of many breeding programs. We have recently shown the existence of a strong causal link between salinity and oxidative stress tolerance in cereals (wheat and barley)...

Monitoring crop and rangeland conditions is highly relevant for early warning and response planning in food insecure areas of the world. Satellite remote sensing can obtain relevant and timely information in such areas where ground data are scattered, non-homogenous, or frequently unavailable. Rainfall estimates provide an outlook of the drivers of vegetation growth, whereas time series of satellite-based biophysical indicators at high temporal resolution provide key information about vegetation status in near real-time and over large areas...

A water resource modeling process is demonstrated to support multistakeholder negotiations over transboundary management of the Nile River. This process addresses the challenge of identifying management options of new hydraulic infrastructure that potentially affects downstream coriparian nations and how the management of existing infrastructure can be adapted. The method includes an exploration of potential management decisions using a multiobjective evolutionary algorithm, intertwined with an iterative process of formulating cooperative strategies to overcome technical and political barriers faced in a transboundary negotiation...

Food security has become a global policy concern due to its important role in sustaining development and human well-being. Using spatial autocorrelation analysis of statistical data at the county-level, this study quantifies the change in spatial and temporal patterns of crop production in the Yangtze River Basin of China since 1990 and draws out policy implications for food security in the country. Four panel models were constructed to examine in what ways and to what extent four major factors (climate variation, sown area, fertilizer use intensity, and population size) influence the capacity for crop production...

Low salinity treatment is proven to be the practical polyploidy inducing method for shellfish with advantages of lower cost, higher operability and reliable food security. However, little is known about the possible molecular mechanism of hypotonic induction. In this study, isobaric tags for relative and absolute quantitation (iTRAQ) based proteomic profiling was pursued to investigate the responses of zygotes of the Pacific oyster Crassostrea gigas to low salinity. A total of 2235 proteins were identified and 87 proteins were considered differentially expressed, of which 14 were up-regulated and 69 were down-regulated...

Drawing on examples from Australia and the United States, we outline the benefits of sharing expertise to identify new approaches to food and nutrition security. While there are many challenges to sharing expertise such as discrimination, academic expectations, siloed thinking, and cultural differences, we identify principles and values that can help food insecurity researchers to improve solutions. These principles are critical consciousness, undoing white privilege, adopting a rights framework, and engaging in co-creation processes...

Based on the Richards-Wolf vectorial diffraction theory and inverse Faraday effect, we first propose a scheme to generate three-dimensional magnetization needle (MN) arrays with arbitrary orientation for each individual needle and controllable spatial position and number by reversing the electric dipole array radiation. To achieve this, each unit of the electric dipole array has two electric dipoles with orthogonal oscillation directions and quadrature phase and is located mirror-symmetric with respect to the focal plane of the high numerical aperture lens...

Car-T Cells are autologous or allogeneic lymphocytes cells, genetically engineered to express a transmembrane receptor called ?chimeric? because it consists of the assembly of different parts of molecules. These new techniques using biotechnologies (cellular engineering and genetic modifications) are developing in a complex legal context integrating the rules of the European Union (EU) and national rules, aiming to guarantee a high level of security for products and techniques but also for patients. This framework can be either considered as a guaranty for the use of new molecules in a highly secure environment or as an impediment, on the one hand regarding those who want to develop them because of a great complexity in identifying the adequate procedures and regarding the scientific prerequisites expected by the control agencies, and on the other hand by patients who have to wait many years for these innovations to be made available...

Compact, bright neutron sources are opening up several emerging applications including detection of nuclear materials for national security applications. At Los Alamos National Laboratory, we have used a short-pulse laser to accelerate deuterons in the relativistic transparency regime. These deuterons impinge on a beryllium converter to generate neutrons. During the initial experiments where these neutrons were used for active interrogation of uranium and plutonium, we observed β-delayed neutron production from decay of 9 Li, formed by the high-energy deuteron bombardment of the beryllium converter...
