Nuclear proliferation in a fragmenting world 13 September 2022 — 1:00PM TO 2:00PM Anonymous (not verified) 5 September 2022 Online

Where does the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) stand in 2022?

With the war in Ukraine and China–US tensions rising, the threat of a nuclear arms race has never been as high since the Cold War.

Global efforts to control the appropriation and use of nuclear weapons are strained with the war in Ukraine, US–Russia and US–China tension, Iran on the nuclear threshold, instability in Pakistan and the ongoing threat from North Korea.

The Review Conference of the NPT that took place in New York this August sought to deal with the multiple nuclear threats, but new missile technology such as hypersonic glide vehicles and torpedoes are not covered by a treaty.

Russia and the US are in a development phase for a host of new technologies and delivery systems, especially after both withdrew from various arms-control treaties in the 2000s and 2010s. Now the nuclear stockpile is growing again and major superpowers are adopting confrontational geostrategic positions.

As the world’s established orders and system fragment, there is a possibility the nine countries with confirmed nuclear weapons could grow. Events in Ukraine highlight the need for a new, modern agreement on nuclear weapons control, needed today more than ever.

The panel of experts discuss key questions including:

• What did ‘RevCon’ in New York tell us about the adoption or update to the NPT?

• Will the war in Ukraine deter or prevent any agreement between nations or does nuclear weapons control represent an area of potential multilateral harmony?

• Are we likely to see a new arms race akin to the Cold War? Where does China fit into this race?

• How has technology changed the arms control landscape?

 As with all Chatham House member events, questions from members drive the conversation.

World in brief: Ukraine and nuclear proliferation to dominate G7 The World Today mhiggins.drupal 28 March 2023

Following Russia’s ongoing intimidation, Japan will use its presidency of the G7 – and its history – to prioritize the dangers of nuclear threats, writes James Orr.

Two issues are expected to dominate the agenda as Japan hosts the G7 summit in Hiroshima from May 19-21. Central to talks will be the conflict in Ukraine, with member states eager to highlight a message of unity and resolve in the face of Russia’s continuing aggression.

Fumio Kishida, Japan’s prime minister, made an unannounced visit to Kyiv on March 21, meeting the Ukrainian president Volodymyr Zelenskyy.  This coincided with a visit to Moscow by China’s leader Xi Jinping, who described Russian president Vladimir Putin as a friend and partner.

‘Absolutely unacceptable’

Hosting the G7 summit in Hiroshima is significant, too, with Kishida expected to emphasize the ‘absolutely unacceptable’ threat of nuclear proliferation. Ongoing tensions between China and Taiwan, together with recent North Korean ballistic missile tests, have heightened fears of a breakdown in security in the region.

Meanwhile, President Vladimir Putin’s menacing references to the use of nuclear weapons in Ukraine has raised the prospect of a potentially devastating conflict with NATO. ‘Kishida’s principal goal for the presidency of the G7 is to try to draw the world away from the path of destruction that is another nuclear conflict,’ said Duncan Bartlett, a research associate at SOAS, the School of Oriental and African Studies, in London.

‘Early last year, Putin warned of terrible consequences if NATO and the West interfered in the Ukraine conflict, and that was widely seen as being a nuclear threat. North Korea is also pursuing its nuclear weapons programme, and in February an intercontinental ballistic missile went into the sea just near the northern Japanese island of Hokkaido,’ said Bartlett.

After Russia invaded Ukraine in February 2022, Kishida has taken a firm position on Putin, in line with his G7 peers. President Zelenskyy has addressed the Japanese parliament via video link and Dmytro Kuleba, Ukraine’s minister of foreign affairs, was invited by his Japanese counterpart to a G7 meeting held during the Munich Security Conference earlier this year.

Kishida committed $600 million in financial support to Ukraine and his government may well announce the provision of further non-lethal assistance to Zelenskyy at the summit. The country’s constitution effectively outlaws the export of deadly weapons to foreign forces. On his visit to Kyiv, Kishida promised a further $30 million to Ukraine.

‘Kishida has revised key defence documents and is pursuing a radical and controversial expansion of Japan’s defence budget and capabilities,’ said Hugo Dobson, Professor of Japan’s International Relations at the University of Sheffield.

‘He and his G7 partners have signed historic defence agreements, pledged to strengthen ties or declared the inseparability of their security in light of actual conflict in Ukraine and potential conflict in East Asia. Kishida has linked the two by emphasizing that Ukraine today may be East Asia tomorrow,’ said Dobson.

Aside from security matters, Kishida will at the summit address issues on clean energy, climate change, global health and boosting multilateral cooperation to drive post-pandemic economic recovery.

Invitation to Nagasaki

He is understood to have invited President Joe Biden to visit Nagasaki, where the second of America’s two atomic bombs is estimated to have killed 60,000 people in August 1945. No sitting US president has ever visited the city, and Kishida, who grew up in Hiroshima, may see the visit as an opportunity to boost his flagging domestic approval ratings. It may also serve as a timely reminder to Russia and others that the G7 opposes any future nuclear weapon use.

Dr. Rekha Thomas from the University of Washington discusses three-dimensional image reconstructions from two-dimensional photos. The mathematics of image reconstruction is both simpler and more abstract than it seems. To reconstruct a 3D model based on photographic data, researchers and algorithms must solve a set of polynomial equations. Some solutions to these equations work mathematically, but correspond to an unrealistic scenario — for instance, a camera that took a photo backwards. Additional constraints help ensure this doesn't happen. Researchers are now investigating the mathematical structures underlying image reconstruction, and stumbling over unexpected links with geometry and algebra.

Dr. Outi Tervo of Greenland Institute for Natural Resources, shares how mathematics helps recommend speed limits for marine vessels, which benefits narwhals and Inuit culture. Narwhals "can only be found in the Arctic," said Outi Tervo, a senior scientist at GINR. "These species are going to be threatened by climate change more than other species that can live in a bigger geographical area." The collaboration has already lobbied on behalf of the narwhals to reduce the level of sea traffic in their habitat, after using mathematical analysis to identify how noise from passing boats changes the narwhals' foraging behavior.

RAS genes are the most commonly mutated in human cancers and play critical roles in tumor initiation, progression, and drug resistance. Identification of targets that block RAS signaling is pivotal to develop therapies for RAS-related cancer. As RAS translocation to the plasma membrane (PM) is essential for its effective signal transduction, we devised a high-content screening assay to search for genes regulating KRAS membrane association. We found that the tyrosine phosphatase PTPN2 regulates the plasma membrane localization of KRAS. Knockdown of PTPN2 reduced the proliferation and promoted apoptosis in KRAS-dependent cancer cells, but not in KRAS-independent cells. Mechanistically, PTPN2 negatively regulates tyrosine phosphorylation of KRAS, which, in turn, affects the activation KRAS and its downstream signaling. Consistently, analysis of the TCGA database demonstrates that high expression of PTPN2 is significantly associated with poor prognosis of patients with KRAS-mutant pancreatic adenocarcinoma. These results indicate that PTPN2 is a key regulator of KRAS and may serve as a new target for therapy of KRAS-driven cancer.

Since the publication of the Age-Related Eye Disease Study (AREDS2) in 2013, the macular pigment carotenoids lutein and zeaxanthin have become well known to both the eye care community and the public. It is a fascinating aspect of evolution that primates have repurposed photoprotective pigments and binding proteins from plants and insects to protect and enhance visual acuity. Moreover, utilization of these plant-derived nutrients has been widely embraced for preventing vision loss from age-related macular degeneration (AMD). More recently, there has been growing awareness that these nutrients can also play a role in improving visual performance in adults. On the other hand, the potential benefits of lutein and zeaxanthin supplementation at very young ages have been underappreciated. In this review, we examine the biochemical mechanisms and supportive data for lutein and zeaxanthin supplementation throughout the lifespan, with particular emphasis on prenatal supplementation. We propose that prenatal nutritional recommendations may aim at improving maternal and infant carotenoid status. Prenatal supplementation with lutein and zeaxanthin might enhance infant visual development and performance and may even prevent retinopathy of prematurity, possibilities that should be examined in future clinical studies.

The neuronal basis of complex social behavior is still poorly understood. In honeybees, reproductive investment decisions are made at the colony-level. Queens develop from female-destined larvae that receive alloparental care from nurse bees in the form of ad-libitum royal jelly (RJ) secretions. Typically, the number of raised new queens is limited but genetic breeding of "royal jelly bees" (RJBs) for enhanced RJ production over decades has led to a dramatic increase of reproductive investment in queens. Here, we compare RJBs to unselected Italian bees (ITBs) to investigate how their cognitive processing of larval signals in the mushroom bodies (MBs) and antennal lobes (ALs) may contribute to their behavioral differences. A cross-fostering experiment confirms that the RJB syndrome is mainly due to a shift in nurse bee alloparental care behavior. Using olfactory conditioning of the proboscis extension reflex, we show that the RJB nurses spontaneously respond more often to larval odors compared with ITB nurses but their subsequent learning occurs at similar rates. These phenotypic findings are corroborated by our demonstration that the proteome of the brain, particularly of the ALs differs between RJBs and ITBs. Notably, in the ALs of RJB newly emerged bees and nurses compared with ITBs, processes of energy and nutrient metabolism, signal transduction are up-regulated, priming the ALs for receiving and processing the brood signals from the antennae. Moreover, highly abundant major royal jelly proteins and hexamerins in RJBs compared with ITBs during early life when the nervous system still develops suggest crucial new neurobiological roles for these well-characterized proteins. Altogether, our findings reveal that RJBs have evolved a strong olfactory response to larvae, enabled by numerous neurophysiological adaptations that increase the nurse bees' alloparental care behavior.

Glutathionylation is an important posttranslational modification that protects proteins from further oxidative damage as well as influencing protein structure and activity. In the present study, we demonstrate that the cysteine-42 residue in protein arginine N-methyltransferase 5 (PRMT5) is glutathionylated in aged mice or in cells that have been exposed to oxidative stress. Deglutathionylation of this protein is catalyzed by glutaredoxin-1 (Grx1). Using mutagenesis and subsequent biochemical analyses, we show that glutathionylation decreased the binding affinity of PRMT5 with methylosome protein-50 (MEP50) and reduced the methyltransferase activity of PRMT5. Furthermore, overexpression of PRMT5-C42A mutant caused a significant increase in histone methylation in HEK293T and A549 cells and promoted cell growth, whereas overexpression of the PRMT5-C42D mutant, a mimic of glutathionylated PRMT5, inhibited cell proliferation. Taken together, our results demonstrate a new mechanism of regulation of PRMT5 methyltransferases activity and suggest that PRMT5 glutathionylation is partly responsible for reactive oxygen species-mediated cell growth inhibition.

Paramphistomosis, caused by the rumen fluke, Calicophoron daubneyi, is a parasitic infection of ruminant livestock which has seen a rapid rise in prevalence throughout Western Europe in recent years. Following ingestion of metacercariae (parasite cysts) by the mammalian host, newly-excysted juveniles (NEJs) emerge and invade the duodenal submucosa which causes significant pathology in heavy infections. The immature larvae then migrate upwards, along the gastrointestinal tract, and enter the rumen where they mature and begin to produce eggs. Despite their emergence, and sporadic outbreaks of acute disease, we know little about the molecular mechanisms used by C. daubneyi to establish infection, acquire nutrients and to avoid the host immune response. Here, transcriptome analysis of four intra-mammalian life-cycle stages, integrated with secretome analysis of the NEJ and adult parasites (responsible for acute and chronic disease respectively), revealed how the expression and secretion of selected families of virulence factors and immunomodulators are regulated in accordance with fluke development and migration. Our data show that whilst a family of cathepsins B with varying S2 sub-site residues (indicating distinct substrate specificities) are differentially secreted by NEJs and adult flukes, cathepsins L and F are secreted in low abundance by NEJs only. We found that C. daubneyi has an expanded family of aspartic peptidases, which is up-regulated in adult worms, although they are underrepresented in the secretome. The most abundant proteins in adult fluke secretions were helminth defence molecules (HDMs) that likely establish an immune environment permissive to fluke survival and/or neutralise pathogen-associated molecular patterns (PAMPs) such as bacterial lipopolysaccharide in the microbiome-rich rumen. The distinct collection of molecules secreted by C. daubneyi allowed the development of the first coproantigen-based ELISA for paramphistomosis which, importantly, did not recognise antigens from other helminths commonly found as co-infections with rumen fluke.

Gonadal soma-derived factor (gsdf) has been demonstrated to be essential for testicular differentiation in medaka (Oryzias latipes). To understand the protein dynamics of Gsdf in spermatogenesis regulation, we used a His-tag "pull-down" assay coupled with shotgun LC-MS/MS to identify a group of potential interacting partners for Gsdf, which included cytoplasmic dynein light chain 2, eukaryotic polypeptide elongation factor 1 alpha (eEF1α), and actin filaments in mature medaka testis. As for the interaction with TGFβ-dynein being critical for spermatogonial division in Drosophila melanogaster, the physical interactions of Gsdf-dynein and Gsdf-eEF1α were identified through a yeast 2-hybrid (Y2H) screening of an adult testis cDNA library using Gsdf as bait, which were verified by a paired Y2H assay. Co-immunoprecipitation of Gsdf and eEF1α was defined in adult testes as supporting the requirement of a Gsdf and eEF1α interaction in testis development. Proteomics analysis (data are available via ProteomeXchange with identifier PXD022153) and ultrastrutural observations showed that Gsdf deficiency activated eEF1α-mediated protein synthesis and ribosomal biogenesis, which in turn led to the differentiation of undifferentiated germ cells. Thus, our results provide a framework and new insight into the coordination of a Gsdf (TGFβ and eEF1α complex in the basic processes of germ cell proliferation, transcriptional and translational control of sexual RNA which may be fundamentally conserved across phyla during sexual differentiation.

Cells continually degrade and replace damaged proteins. However, the high energetic demand of protein turnover generates reactive oxygen species (ROS) that compromise the long-term health of the proteome. Thus, the relationship between aging, protein turnover and energetic demand remains unclear. Here, we used a proteomic approach to measure rates of protein turnover within primary fibroblasts isolated from a number of species with diverse lifespans including the longest-lived mammal, the bowhead whale. We show that organismal lifespan is negatively correlated with turnover rates of highly abundant proteins. In comparison to mice, cells from long-lived naked mole rats have slower rates of protein turnover, lower levels of ATP production and reduced ROS levels. Despite having slower rates of protein turnover, naked mole rat cells tolerate protein misfolding stress more effectively than mouse cells. We suggest that in lieu of rapid constitutive turnover, long-lived species may have evolved more energetically efficient mechanisms for selective detection and clearance of damaged proteins.

Tackling Illegal Wildlife Trade in Africa: Economic Incentives and Approaches Research paper sysadmin 5 October 2018

Combating illegal wildlife trade and further pursuing conservation-development models could help generate considerable economic benefits for African countries, while ensuring the long-term preservation of Africa’s wealth of natural capital.

Summary

• The illegal wildlife trade (IWT) significantly impacts African economies by destroying and corroding natural, human and social capital stocks. This hinders the achievement of the Sustainable Development Goals (SDGs) and has an impact on national budgets. Illicit financial flows from IWT deny revenue to governments where legal wildlife product trade exists and perpetuate cash externalization. IWT diverts national budgets away from social or development programmes, increases insecurity and threatens vulnerable populations.
• In expanding wildlife economies and pursuing conservation-driven development models, governments can protect their citizens, derive revenue from wildlife products, and establish world class tourism offerings. The illegal exploitation of wildlife is often due to a failure to enforce rights over those resources, where rights are unclearly defined or not fully exercised. Southern African countries have defined these rights in various ways, contributing to regional differences in conservation practices and the socio-economic benefits derived from wildlife resources. Combating IWT is an important step towards allowing legitimate business and communities to develop livelihoods that incentivize stewardship and connect people to conservation.
• The Southern African Development Community (SADC) has several framework policies for the establishment of transfrontier conservation areas (TFCAs). These promote local stewardship across multiple land-use areas to conserve biodiversity and increase the welfare and socioeconomic development of rural communities. Private-sector partnerships also increase skills transfer, improve access to investment finance, and expand economic opportunities, including through the promotion of local procurement. The economic benefits of TFCAs extend beyond tourism.
• The economic value of African ecosystems is often under-recognized because they remain unquantified, partly due to the lack of available data on the broader economic costs of IWT. Improved monitoring and evaluation with key performance indicators would help governments and citizens to appreciate the economic value of combating IWT.
