Hello team!

I turned 45! It happens every year (not the same age, but the same feeling, of time marching forward, with me along with it) so no big surprise. This weekend was the Great Race, also every year, but I unsubscribed from their e-mail list at some point months ago because they seem to operate this list under the misconception that subscribers want to think about Great Race 24/7 all year round. I thought: It should be easy to just remember when the Great Race is, as it always falls on the weekend near my birthday, and I do not need a list constantly mailing me reminders. Easy. But then I forgot about the Great Race, so I didn't run it.

I did take the day off for my birthday despite this being the busy time of year at work, which was worth it: I made some good progress on some projects that had been backed up in my anxiety-brain for some time. Of course they are confidential, but here is a graphic of some significant progress:

I forgot to mention this one when I did it, but did you know that you can "buy" a Unicode codepoint, by making a donation to the Unicode consortium? So of course I bought ASCII 0x37, which is the digit 7.

True story: I did a lot of film photography when I was younger, and although I do miss film, I'll admit that the saddest thing I feel about its obsolescence is actually that those little black plastic film canisters are no longer all over the place to be repurposed to hold little objects. I found them very satisfying and useful! Fortunately now that I'm old I found another similar ubiquitous shape, which is these orange prescription medicine bottles. I've been using those for a while to "organize" small parts like screws (e.g. when I take something apart that I might want to put back together, I put the screws in the medicine bottle and label it) but then they just roll around in the drawer of crap. So this:


RxBox, Unpopulated
RxBox, Populated

A very simple part, of course, but what could be more satisfying than 3d printing your own holder for canisters for fasteners that goes in a drawer in a cabinet?

And speaking of satisfying, I finally finished Chippy (regular difficulty) which was really quite hard. Several of the last bosses I had to practice over several evenings before I beat them! It was a good and creative game, though. I'm mid-way through Solar Ash, which is good (but it's no Hyper Light Drifter IMO!) and just started playing Satisfactory, since they finally put out a 1.0 version of that. It's quite well done, but I'm not sure if I actually like it (seems a bit heavy on the cookie crafting; in fact I'm letting it craft in the background as I write this). I am getting a kick out of allowing thinking about my messy design as the "saddest factory," a joke which I'm sure occurs to everyone, but that's Game Design!

The Democratic Republic of the Congo’s foreign policy priorities 29 October 2024 — 1:00PM TO 2:00PM Anonymous (not verified) 18 October 2024 Chatham House and Online

The DRC’s Minister of Foreign Affairs discusses the country’s approach to regional stability and the role of international partnerships in securing economic prosperity.

At this event, HE Thérèse Kayikwamba Wagner, Minister of Foreign Affairs of the DRC, will discuss DRC’s regional diplomatic priorities and international agency, including its ambitions around global critical mineral supply chains.

The Democratic Republic of the Congo (DRC) faces foreign policy tests as it manages a complex security crisis and regional tensions, alongside global economic and trade partnerships.

Entrenched conflict in eastern DRC continues to have wider regional implications. Troops from the Southern African Development Community (SADC) deployment are tackling a growing mandate as the UN’s peacekeeping mission prepares to withdraw. Tensions with Rwanda also remain high despite mediation efforts under the Luanda process.

As a major producer of critical minerals for the global energy transition, the DRC seeks to benefit from growing international demand without sacrificing value addition. New and existing frameworks with international partners will remain key to this vision, including for the development of regional infrastructure networks such as the Lobito Corridor.

At this event, HE Thérèse Kayikwamba Wagner, Minister of Foreign Affairs of the DRC, will discuss the DRC’s regional diplomacy and international agency, including the country’s positioning in global critical mineral supply chains.

Please note that in-person attendance for this event will be balloted. Guests looking to join in-person must register interest in joining. Full confirmations to successful applicants will be sent on Friday 25 October.

The 2020 Inner Mongolia Language Protests: Wider Meanings for China and the Region 24 November 2020 — 3:00PM TO 4:00PM Anonymous (not verified) 12 November 2020 Online

Speakers discuss the historical roots of the language issue, as well as the wider significance of the protests in China.

Please note this is an online event. Please register on Zoom using the link below to secure your registration.

In September thousands of people protested in Inner Mongolia in opposition to a government move to replace Mongolian language with Standard Mandarin in three school subjects – history, politics and Chinese language.

Announced less than a week before the start of the new school year, the policy also requires schools to use new national textbooks in Chinese, instead of regional textbooks. The mass protests and classroom walk-outs reflect ethnic Mongolian’s anxiety that their native language may be eliminated. What has the government’s response to the protests been?

Sphingolipids have emerged as bioactive lipids involved in the regulation of many physiological and pathological processes. In the retina, they have been established to participate in numerous processes, such as neuronal survival and death, proliferation and migration of neuronal and vascular cells, inflammation, and neovascularization. Dysregulation of sphingolipids is, therefore, crucial in the onset and progression of retinal diseases. This review examines the involvement of sphingolipids in retinal physiology and diseases. Ceramide (Cer) emerges as a common mediator of inflammation and death of neuronal and retinal pigment epithelium cells in animal models of retinopathies such as glaucoma, age-related macular degeneration (AMD), and retinitis pigmentosa. Sphingosine-1-phosphate (S1P) has opposite roles, preventing photoreceptor and ganglion cell degeneration but also promoting inflammation, fibrosis, and neovascularization in AMD, glaucoma, and pro-fibrotic disorders. Alterations in Cer, S1P, and ceramide-1-phosphate may also contribute to uveitis. Notably, use of inhibitors that either prevent Cer increase or modulate S1P signaling, such as Myriocin, desipramine, and Fingolimod (FTY720), preserves neuronal viability and retinal function. These findings underscore the relevance of alterations in the sphingolipid metabolic network in the etiology of multiple retinopathies and highlight the potential of modulating their metabolism for the design of novel therapeutic approaches.

The backbone of all sphingolipids (SLs) is a sphingoid long-chain base (LCB) to which a fatty acid is N-acylated. Considerable variability exists in the chain length and degree of saturation of both of these hydrophobic chains, and recent work has implicated ceramides with different LCBs and N-acyl chains in distinct biological processes; moreover, they may play different roles in disease states and possibly even act as prognostic markers. We now demonstrate that the half-life, or turnover rate, of ceramides containing diverse N-acyl chains is different. By means of a pulse-labeling protocol using stable-isotope, deuterated free fatty acids, and following their incorporation into ceramide and downstream SLs, we show that very-long-chain (VLC) ceramides containing C24:0 or C24:1 fatty acids turn over much more rapidly than long-chain (LC) ceramides containing C16:0 or C18:0 fatty acids due to the more rapid metabolism of the former into VLC sphingomyelin and VLC hexosylceramide. In contrast, d16:1 and d18:1 ceramides show similar rates of turnover, indicating that the length of the sphingoid LCB does not influence the flux of ceramides through the biosynthetic pathway. Together, these data demonstrate that the N-acyl chain length of SLs may not only affect membrane biophysical properties but also influence the rate of metabolism of SLs so as to regulate their levels and perhaps their biological functions.

Sphingolipids have become established participants in the pathogenesis of obesity and its associated maladies. Sphingosine kinase 1 (SPHK1), which generates S1P, has been shown to increase in liver and adipose of obese humans and mice and to regulate inflammation in hepatocytes and adipose tissue, insulin resistance, and systemic inflammation in mouse models of obesity. Previous studies by us and others have demonstrated that global sphingosine kinase 1 KO mice are protected from diet-induced obesity, insulin resistance, systemic inflammation, and NAFLD, suggesting that SPHK1 may mediate pathological outcomes of obesity. As adipose tissue dysfunction has gained recognition as a central instigator of obesity-induced metabolic disease, we hypothesized that SPHK1 intrinsic to adipocytes may contribute to HFD-induced metabolic pathology. To test this, we depleted Sphk1 from adipocytes in mice (SK1^fatKO) and placed them on a HFD. In contrast to our initial hypothesis, SK1^fatKO mice displayed greater weight gain on HFD and exacerbated impairment in glucose clearance. Pro-inflammatory cytokines and neutrophil content of adipose tissue were similar, as were levels of circulating leptin and adiponectin. However, SPHK1-null adipocytes were hypertrophied and had lower basal lipolytic activity. Interestingly, hepatocyte triacylglycerol accumulation and expression of pro-inflammatory cytokines and collagen 1a1 were exacerbated in SK1^fatKO mice on a HFD, implicating a specific role for adipocyte SPHK1 in adipocyte function and inter-organ cross-talk that maintains overall metabolic homeostasis in obesity. Thus, SPHK1 serves a previously unidentified essential homeostatic role in adipocytes that protects from obesity-associated pathology. These findings may have implications for pharmacological targeting of the SPHK1/S1P signaling axis.

Multiple sclerosis (MS) is a CNS disease characterized by immune-mediated demyelination and progressive axonal loss. MS-related CNS damage and its clinical course have two main phases: active and inactive/progressive. Reliable biomarkers are being sought to allow identification of MS pathomechanisms and prediction of its course. The purpose of this study was to identify sphingolipid (SL) species as candidate biomarkers of inflammatory and neurodegenerative processes underlying MS pathology. We performed sphingolipidomic analysis by HPLC-tandem mass spectrometry to determine the lipid profiles in post mortem specimens from the normal-appearing white matter (NAWM) of the normal CNS (nCNS) from subjects with chronic MS (active and inactive lesions) as well as from patients with other neurological diseases. Distinctive SL modification patterns occurred in specimens from MS patients with chronic inactive plaques with respect to NAWM from the nCNS and active MS (Ac-MS) lesions. Chronic inactive MS (In-MS) lesions were characterized by decreased levels of dihydroceramide (dhCer), ceramide (Cer), and SM subspecies, whereas levels of hexosylceramide and Cer 1-phosphate (C1P) subspecies were significantly increased in comparison to NAWM of the nCNS as well as Ac-MS plaques. In contrast, Ac-MS lesions were characterized by a significant increase of major dhCer subspecies in comparison to NAWM of the nCNS. These results suggest the existence of different SL metabolic pathways in the active versus inactive phase within progressive stages of MS. Moreover, they suggest that C1P could be a new biomarker of the In-MS progressive phase, and its detection may help to develop future prognostic and therapeutic strategies for the disease.

Fabry disease is caused by deficient activity of α-galactosidase A, an enzyme that hydrolyzes the terminal α-galactosyl moieties from glycolipids and glycoproteins, and subsequent accumulation of glycosphingolipids, mainly globotriaosylceramide (Gb₃), globotriaosylsphingosine (lyso-Gb₃), and galabiosylceramide. However, there is no known link between these compounds and disease severity. In this study, we compared Gb₃ isoforms (various fatty acids) and lyso-Gb₃ analogs (various sphingosine modifications) in two strains of Fabry disease mouse models: a pure C57BL/6 (B6) background or a B6/129 mixed background, with the latter exhibiting more prominent cardiac and renal hypertrophy and thermosensation deficits. Total Gb₃ and lyso-Gb₃ levels in the heart, kidney, and dorsal root ganglion (DRG) were similar in the two strains. However, levels of the C20-fatty acid isoform of Gb₃ and particular lyso-Gb₃ analogs (+18, +34) were significantly higher in Fabry-B6/129 heart tissue when compared with Fabry-B6. By contrast, there was no difference in Gb₃ and lyso-Gb₃ isoforms/analogs in the kidneys and DRG between the two strains. Furthermore, using immunohistochemistry, we found that Gb₃ massively accumulated in DRG mechanoreceptors, a sensory neuron subpopulation with preserved function in Fabry disease. However, Gb₃ accumulation was not observed in nonpeptidergic nociceptors, the disease-relevant subpopulation that has remarkably increased isolectin-B4 (the marker of nonpeptidergic nociceptors) binding and enlarged cell size. These findings suggest that specific species of Gb₃ or lyso-Gb₃ may play major roles in the pathogenesis of Fabry disease, and that Gb₃ and lyso-Gb₃ are not responsible for the pathology in all tissues or cell types.

Angola Forum 2018: 30th Anniversary of the Battle of Cuito Cuanavale 23 March 2018 — 10:00AM TO 2:30PM Anonymous (not verified) 8 March 2018 Chatham House, London

Reflections on Southern Africa’s Turning Point

23 March 2018 marks the 30th anniversary of the final assault of what became known as the Battle of Cuito Cuanavale.

The confrontation between the Angolan army, supported by Cuba and the Soviet Union, and the armed opposition UNITA, supported by the South African Defence Force, is the largest land battle to have taken place in Africa since World War Two.

The battle was a watershed in Angolan and southern African history, but its significance continues to be contested. Today, although the battlefield has a monument and museum, it remains one of the most landmine-contaminated parts of Angola and this hinders development plans for international tourism.

This event brings together veterans and experts to contribute towards developing a deeper understanding of the battle. Discussions will further focus on the significance of the wider events around the battle, its regional implications, as well as the legacy of the battlefield.

Political Reform in Angola: Challenges and Priorities for Elected Officials 31 October 2018 — 4:00PM TO 5:00PM Anonymous (not verified) 26 October 2018 Chatham House, London

Angola’s reformulated National Assembly has passed a series of legislative reforms since elections in August 2017, in which the ruling MPLA won a majority of 150 seats to the 51 held by the UNITA leading opposition party.

Many of the changes have targeted the revitalization of an underperforming economy and improved governance: in June 2018 parliament approved a new private investment law aimed at diversifying Angola’s fiscal base beyond oil revenues while new legislation in May mandated the return of illicitly exported capital of over $100,000.

As the appetite for measurable progress across all sectors of society remains high, and with newly constituted municipal elections scheduled for 2020, inclusive and accountable political debate will remain critical to Angola’s future.

At the event, a cross-party delegation discuss the role of the National Assembly in affecting political change and the importance of maintaining open dialogue among opposing voices to address the challenges facing Angola.

Mine Action in Angola: Clearing the Legacies of Conflict to Harness the Potential of Peace Other resource sysadmin 14 June 2019

This publication draws on and updates the briefing note published following a meeting of the All- Party Parliamentary Group (APPG) on Angola on 26 April 2017. It also incorporates insights from a Chatham House Africa Programme conference session on the legacies of the Angolan Civil War, held on 23 March 2018; and draws on the Africa Programme’s research into conservation-driven development models in Southern Africa.

Almost two decades after the end of its civil war, Angola remains one of the most heavily landmine-contaminated countries in the world. The Angolan government has committed to clearing its landmines by 2025, and there is constructive collaboration between the government and mine clearing agencies in this endeavour, but the target will be achievable only if a decline in funding from international donors is reversed. International funding for mine clearance in Angola fell by more than 80 per cent between 2005 and 2017, and this sharp drop in external support has compounded the impact on domestic funding for national clearance efforts as a result of the downturn in prices for Angola’s main export commodities.

The national mine action agency, the Comissão Nacional Intersectorial de Desminagem e Assistência Humanitária (CNIDAH), is supported by the Mines Advisory Group (MAG), Norwegian People’s Aid (NPA) and the HALO Trust. By 2017, 15 years after the end of the civil war, these organizations had collectively helped clear 56 per cent of known landmine-contaminated land. State-led demining has focused principally on clearing areas designated for infrastructure projects. Now, it is critical that humanitarian demining in largely agricultural and conservation areas is prioritized to bring to an end the daily threat to Angola’s rural poor – as well as to the country’s livestock and wildlife – of injury or death as a result of landmine accidents.

Angola has some of the world’s most important remaining wilderness, including the tributary system for the unique Okavango Delta, and the country has the potential to host one of the most diverse wildlife populations on the continent. However, the presence of landmines and other remnants of the civil war render large areas of the country unsafe both for wildlife and for the local people, whose ability to derive a sustainable livelihood from their natural environment is fundamental to its protection.

Wildlife and tourism provide important economic opportunities for diversification beyond an oil-dominated economy. Critically, Angola’s economic diversification and development objectives can only be achieved if the landmines that prohibit access to land for agriculture, mining, tourism and wildlife are cleared.

There are economic opportunities for released land in the most heavily mined provinces of Cuando Cubango and Moxico. Already, some new funding for mine action in Angola, if upscaled or matched by international donors, could be transformative for its people, and for the conservation of the region’s vital biodiversity.
