Food is one of the most traded goods, and the conflict in Ukraine, one of the European breadbaskets, has triggered a significant additional disruption in the global food supply chains after the COVID-19 impact. The disruption to food output, supply chains, availability, and affordability could have a long-standing impact. As a result, the availability and supply of a wide range of food raw materia
During translation, mRNA molecules are incidentally damaged, leaving the ribosome unable to reach or recognize the stop codon and thus stalled with mRNA and a potentially harmful polypeptide product attached to tRNA in the ribosomal P-site. In bacteria, a process called trans-translation has evolved, where a protein-RNA complex (smpB-tmRNA) mimicks the role of aminoacyl charged tRNA in the ribosom
The assumption that voters systematically defend the welfare state is challenged by recent research showing that parties are on average not punished and sometimes even rewarded for welfare state retrenchment. We work to understand better the micro-foundations for this finding of non-punishment by exploring individuals’ preferences over social policy. In particular, we distinguish general support f
Background: The global community has committed to achieving universal access to sexual and reproductive health and rights (SRHR) services, but how to do it remains a challenge in many low-income countries. Capacity development is listed as a means of implementation for Agenda 2030. Although it has been a major element in international development cooperation, including SRHR, its effectiveness and
Building on the base of the existing telescopes of the Event Horizon Telescope (EHT) and ALMA, the next-generation EHT (ngEHT) aspires to deploy ∼10 more stations. The ngEHT targets an angular resolution of ∼15 microarcseconds. This resolution is achieved using Very Long Baseline Interferometry (VLBI) at the shortest radio wavelengths ∼1 mm. The Submillimeter Array (SMA) is both a standalone radio
Vertebrate photoreceptors have been studied for well over a century, but a fixed nomenclature for referring to orthologous cell types across diverse species has been lacking. Instead, photoreceptors have been variably—and often confusingly—named according to morphology, presence/absence of ‘rhodopsin’, spectral sensitivity, chromophore usage, and/or the gene family of the opsin(s) they express. He
This Regional Outlook focuses on the obstacles of delivering humanitarian aid to Gaza and the challenges of rebuilding and reconstructing the area after the war.
Vegetation growth may adapt to climate warming by adjusting the relationship between photosynthetic capacity and temperature. However, changes in the optimal temperature for ecosystem productivity during recent decades of warming remain uncertain. Here we provide empirical evidence that global optimal temperature increased at a rate of 0.017 ± 0.002 °C y−1 from 1982 to 2016, using multiple dataset
The emergence of pandemics like Covid-19 has raised important issues regarding the safe utilisation of spaces due to the potential for virus transmission in both enclosed and open built environments. This chapter explores the challenges posed by pandemics in terms of safe space utilisation, considering the potential virus transmission risks. It presents a risk analysis methodology that makes use o
Within a collaboration between MAX-lab and BESSY a one stage seeded HGHG-FEL has been set up at Maxlab. BESSY has built the undulator system consisting of a modulator, a radiator and an electromagnetic chicane. BESSY has also installed three types of diagnostic tools: optical fibres for a fast Cherenkov beam loss detection, optical fibres for absolute dose measurements via their radiation-induced
In this paper we study the propagation problem of a time harmonic electro- magnetic field inside a cavity filled with a generic bianisotropic medium. We define the concepts of eigenfrequencies and modes of the cavity and we prove their existence and countability. We extend, in this respect, the theory for the isotropic, homogeneous, lossless cavity.
The Ezrin/Radixin/Moesin (ERM) family of proteins act as cross-linkers between the plasma membrane and the actin cytoskeleton. This mechanism plays an essential role in processes related to membrane remodeling and organization, such as cell polarization, morphogenesis and adhesion, as well as in membrane protein trafficking and signaling pathways. For several human aquaporin (AQP) isoforms, an int
