action “Distraction,” Simplicity, and Running Toward Shitstorms By www.43folders.com Published On :: Tue, 05 Oct 2010 23:49:56 +0000 It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience. —Albert Einstein, “On the Method of Theoretical Physics” (1934) Context: Last week, I pinched off one of my typically woolly emails in response to an acquaintance whom I admire. He’s a swell guy who makes things I love, and he'd written, in part, to express concern that my recent Swift impersonation had been directed explicitly at something he'd made. Which, of course, it hadn’t—but which, as I'll try to discuss here, strikes me as irrelevant. To paraphrase Bogie, I played it for him, so now I suppose I might as well play it for you. (n.b.: Excerpted, redacted, munged, and heavily expanded from my original email) There are at least a couple things that mean a lot to me that I'm still just not very good at. Make nuanced points in whatever way they need to be made; even if that ends up seeming “un-nuanced” Never explain yourself. I want to break both these self-imposed rules privately with you here. [Editor’s Note: Um.] Because, I hope to nuance the shit out of some fairly un-nuanced points. And, to do that, I'll also (reluctantly) need to explain myself. But, here goes. First [regarding my goofing on “distraction-free writing environments”] I think there are some GIANT distinctions at play here that a lot of folks may not find nearly as obvious as I do: Tool Mastery vs. Productivity Pr0n – Finding and learning the right tools for your work vs solely dicking around with the options for those tools is just so important, but also so different. And, admittedly, it’s almost impossible to contrast those differences in terms of hard & fast rules that could be true for all people in all situations. But, that doesn’t make the difference any less qualitatively special or real. Similarly… Self-Help Vs. “Self”–“Help” – Solving the problem that caused the problem that caused the problem that caused the symptom we eventually noticed. Huge. Arguably, peerless. Viz.: How many of us ignore the actual cause of our problem in favor of just reading dozens of blog posts about how to “turbocharge” its most superficial symptoms? Sick. Focus & Play – Yes, focusing on important work is, as Ford used to say, Job 1. But, that focus benefits when we maintain the durable and unapologetic sense of play that affords true creativity and fosters an emergence of context and connection that’s usually killed by stress. BUT. Again, what conceivable “rule” could ever serve to immutably declare that “THIS goofing-off is critical for hippocampal plasticity” vs. “THAT goofing-off is just dumb, distracting bullshit?” Impossible. Because drawing those kinds of distinctions is one of our most important day-to-day responsibilities. Decisions are hard, and there’s no app or alarm gadget that can change that. Although, they certainly can help mask the depth of the underlying problem that made them seem so—what’s the parlance?—“indispensable”. Think: Elmo Band-Aids for that unsightly pancreatic tumor. Reducing Distraction through Care (Rather than braces, armatures, and puppet strings). Removing interruptions and external distractions that harm your work or life? Great. Counting on your distraction-removal tool to supplement your non-existent motivation to do work that will never get done anyway? Pathetic. Frankly, this is a big reason I'm so galled when anyone touts their tool/product/service as being the poor, misunderstood artist’s new miracle medicine—rather than just admitting they've made a slightly different spoon. Because, let’s be honest: although most of us have plenty of perfectly serviceable spoons, everybody knows collecting cutlery is way more fun than using it to swallow yucky medicine. Using a System Vs. Becoming a System. Having a system or process for getting work done vs. making the iteration of that system or process a replacement for the work. This is just…wow…big. But, maybe most importantly to me… Embracing the Impossibles. Getting past these or any other intellectual koans by simply accepting life’s innumerable and unresolvable paradoxes, hypocrisies, and impossibilities as God-given gifts of creative constraint. Rather than, say, a mimeographed page of long division problems that must be solved for a whole number, n. I just can’t ever get away from this one. For me, it’s what everything inevitably comes back to. The very definition of our jobs is to solve the right problem at the right level for the right reason—based on a combination of the best info we have for now and a clear-eyed dedication to never pushing an unnecessary rock up an avoidable hill. YET, we keep force-feeding the monster that tells us to fiddle and fart and blame the Big Cruel World whenever we face work that might threaten our fragile personal mythology. “Sigh. I wish I could finally start writing My Novel….Ooooooh, if only I had a slightly nicer pen…and Zeus loved me more….” All that stuff? That there’s a complex set of ideas to talk about for many complex reasons—not least of which being how many people either despise or (try to) deny the unavoidable impact of ol' number six. But, here’s the thing: as much as saying so pisses anybody off, I think the topics we're NOT talking about whenever we disappear into Talmudic scholarship about “full-screen mode” or “minimalist desks” or whatever constitutes a “zen habit”—those shunned topics are precisely the things that I believe are most mind-blowingly critical to our real-world happiness as humans. In fact, I believe that to such a degree that helping provide a voice for those unpopular topics that can be heard over the din is now (what passes for) my career. I really believe these deeper ideas are worth socializing on any number of levels and in many media. Even when it’s inconvenient and slightly disrespectful of someone’s business model. So, that’s what I try to do. I talk about these things. Seldom by careful design. Often poorly. But, always because they each mean an awful lot to me. […] But, no matter how I end up saying whatever the hell I say, I believe in saying it not simply to be liked or followed or revered as a “nice guy” who pushes out shit-tons of whatever to “help people.” Because, believe me, friend, a great many of those apparently “nice guys” swarming around the web “helping people” these days are ass-fucking their audience for nickels and calling it a complimentary colonoscopy. And, while I absolutely think that in itself is empirically wrong, I also think it’s just as important to say that it’s wrong. Sometimes, True Things need to be said. Which in this instance amounts to saying, a) selling people a prettier way to kinda almost but not really write is not, in the canonical sense, “nice”—but, far worse, b) leaving your starry-eyed customers with the nauseatingly misguided impression that their “distraction” originates from anyplace but their own busted-ass brain is really not “helping.” Not on any level. It is, literally, harmful. “Helping” a junkie become more efficient at keeping his syringe loaded is hardly “nice.” It’s the opposite of nice. And, it’s the opposite of helpful. These are my True Things. And, to me, saying your True Things also means not watering down the message you care about in order to render it incapable of even conceivably hurting someone’s feelings—or of even conceivably losing you even one teeny-tiny slice of that precious “market share.” Well, that’s the price, and I'm fine paying it—best money I've ever spent. But, it also means trusting your audience by letting each of them decide to add water only as they choose to—by never corrupting the actual concentrate in a way that might make it less useful to the smartest or most eager 5% of people who'd like to try using it undiluted. Because, at that point, you're not only abandoning the coolest people you have the honor of serving—you risk becoming a charlatan. And, that’s precisely what you become when you start to iteratively inbreed the kind of fucktard audience for whom daily buffets of weak swill and beige assurance are life’s most gratifying reward. Sure. Those poor bastards may never end up using any of that watery information to do anything more ambitious than turbocharging their most regrettable symptoms. But, who’s the last person in the universe who’s going to grab them by the ears and tell them to get back to work? Exactly—that same “nice guy” whose livelihood now depends on keeping infantalized strangers addicted to his “help.” Holy shit—no way could I ever live with that. It’s so wrong, it’s not even right. ESC, ESC, ESC! […] Okay. So anyhow, there’s a really long-winded, overly generous, and extremely pompous way of trying to say I don’t know how to do what I do except how I do it. But, I do genuinely feel awful when innocent people feel they have been publicly humiliated or berated simply because I'm some dick who hates people. Which has to be my favorite irony of all. When I was a kid, I thought my Mom was “mean” not to let me play in traffic on busy Galbraith Road. Today, I'm not simply grateful that she had the strength and resolve to be so “mean”—I actually can’t imagine how sad it would be to not have people in your life who care enough about your long-term welfare to tell you to stop fucking around in traffic. To where you eventually might start even seeking 12x-daily safety hacks from some of the very same drivers whose recklessness may eventually kill you. Wow. […] Admitting when life is complicated or things aren’t shiny and happy all the time strikes me as a wonderfully sane and adult way to conduct one’s life. That there are so many folks offended by even the existence of this anarchic idea is not a problem I can solve. No more than I can wish useless email away or pray hard enough that it never rains on anyone’s leaky roof. All out of scope. And, then, I jizzed on at length about how much I admire the recipient’s work. Which I do. Good work doesn’t need a cookie I may admire your work, too. Especially if you care a lot about that work and don’t overly sweat peoples' opinions of it. Most definitely including my own. For these purposes, it doesn’t really matter whether we're friends and, honestly, it doesn’t even matter whether I love, use, or agree with everything you do, say, or make in a given day. It doesn’t matter because good work doesn’t need me to love it. Like tornadoes and cold sores, good work happens with total disregard to whether I'm “into it.” But, conversely, let’s stipulate that the points-of-view undergirding our opinions—again, including mine—will and should survive either agreement or lack of agreement with equivalently effortless ease. Because, like really good work, a really good point-of-view doesn’t require another person’s benediction. Guess we'll have to disagree to agree Now, to be only vaguely clearer here, I'm not posting this circuitous ego dump in the service of altering your opinion of either me, my friend, his work, or practically anything else for that matter. But, I would love it if we could all be more okay with the fact that real life means that we do each have a different, sometimes incongruous, and often totally incompatible point-of-view. Yes. Even you have a point-of-view that someone despises. Ready to change it now? Jesus, I sure hope not. Then, to be only slightly more clear, I'm also not advocating for that fakey brand of web-based kum ba ya that gets trotted out alternately as “tolerance” or “inclusion” or some styrofoam miniature of “civility.” I'm absolutely not against all of those things when authentically practiced, but I'm also really skeptical of the well-branded peacemakers who are forever appointing themselves the Internet’s “Now-Now-Let’s-All-Pretend-We're-Just-Saying-the-Same-Useless-Thing-Here” den mothers. Because we're not all saying the same things. Not at all. And, it infantalizes some important conversations when we tacitly demand that any instance of honest disagreement be immediately horseshat into a photo opp where some thought leader gets to hoist everyone’s hands in the air like he’s fucking Jimmy Carter. Nope. Not saying that. Who will you really rely on? What I AM saying is that alllllll this seemingly unrelated stuff is absolutely related—that the pattern of not relying on other people for anything you really care about is arguably the great-grandaddy of every useful productivity, creativity, or self-help pattern. Where’s this matter? Pretty much everywhere you have any sort of stake: Don’t rely on other people to remove your totally fake “distractions.” Don’t rely on other people to pat your beret, re-tie your cravat, and make you a nice cocoa whenever that mean man on the internet points out that your “distractions” are totally fake. (Which they are) Don’t rely on other people to tell you when or whether you have enough information. Don’t rely on other people to define your job. Don’t rely on other people to “design your lifestyle.” Don’t rely on other people to decide when your opinions are acceptable. Don’t rely on other people to tell you when you're allowed to be awesome. Don’t rely on other people to make you care. Don’t even rely on other people to tell you what you should or shouldn’t rely on. Yes. I went there. Because that’s the point. These hypocrisies, paradoxes, and ambiguities that people get so wound up about—that many of us are constantly (impotently) trying to resolve—cannot be resolved. Because, yeah: all of these harrowingly unsolvable problems are immune to new notebooks and less-distracting applications and shinier systems and “nicer” self-“help” and pretty much anything else that is not, specifically, you walking straight into the angriest and least convenient shitstorm you can find and getting your ass kicked until the storm gets bored with kicking it. Then, you find an even angrier storm. Then, another. And, so on. “Get the fuck off of my obstacle, Private Pyle!” Doing that annoying hard stuff is how you grow, get better, and learn what real help looks like. Even if that’s not the answer you wanted to hear. You get better by getting your ass out of your RSS reader and fucking making things until they suck less. Not by buying apps. You don’t whine about distractions, or derail yourself over needing a nicer pencil sharpener, or aggravate your chronic creative diabetes by starting another desperate waddle to the self-help buffet. No. You work. And, for what it’s worth, just like you can’t get to the moon by eating cheese, you'll also never leave boot camp with your original scrote intact by telling your drill sergeant to try using more honey than vinegar. No. That sergeant’s job is to make you miserable. It’s his job to break down your callow conceits about what’s supposed to be easy and fair. It’s his job to emotionally pummel you into giving up and becoming a Marine. You? You're not there to give the sergeant notes; you're there to sleep two hours a night, then not mind getting beaten for 20 hours until a decent Marine starts to fall out. Who knows? He may even surprise you by introducing a surprisingly effective “distraction-free learning environment.” “Tee ell dee ahr, Professor Brainiac.” Like most humans, I like things I can understand. Like most readers, I love specificity. Like most thinkers, I love clarity. Like most students, I love relevance and practicality. And, like most busy people, believe it or not, I actually do really like it when someone gets straight to the point. But, here’s the problem. If my 2-year-old daughter asks me about time travel, and I blithely announce, “E=mc2”, I will have said something that is entirely specific, clear, relevant, practical, and/or straight-to-the-point. For somebody. But, not so much for my daughter. And, to be honest, not even to any useful degree for me. She'd probably either laugh derisively at me (which she’s great at), or she'd pause and ask, “Whuh dat?” (which she’s even better at). Thing is, her understanding that jumble of characters less than me—and my understanding it WAY less than Professor Al—has zero impact on the profundity, truth, beauty, or impact of the man’s theory. Sure. You could quite accurately fault me for being a smartass and a poseur, and you could even berate my toddler for her unaccountably shallow understanding of Modern Physics. But, in any case, you can’t really blame either Albert or his theory. You're turbocharging nothing Specifically, Albert can’t begin to tell us what he really knows if we don’t understand math. So, let’s say this theory you've been hearing about really interests you. And, let’s also pretend, just for the sake of the analogy, that you haven’t completed Calculus III (212) or Quantum Mechanics (403) or even something as elementary as, say, Advanced Astrophysics II (537). I know you have. Obviously. But, let’s pretend. Where do you start? Well, you could read some tips about learning math. You could find a list of 500 indispensable resources for indispensable math resources. You could buy a new “distraction-free math environment.” Heck, there’s actually nothing to stop you from just declaring yourself a “math expert.” Congratulations, Professor. Thing is: you still don’t know math. Which means you still can’t really understand the theory—no more than a pathetic Liberal Arts refugee like me or a dullard Physics ignoramus like my kid can really grok relativity. Difference is, you will have blown a lot of time hoping that actual expertise follows non-existent effort—while my daughter and I get to remain total novices without charge. Only, we don’t get all mad at the theory as a result; a staggering number of fake math experts do. I mean, be honest—after all that recreational non-work and make-believe dedication almost trying to kinda learn math sorta—you might actually get frustrated at how brazenly Al defies your fondness for shortcuts by continuing to rely on so many terms and proofs and blah-blah-blah that you still just don’t understand. So annoying. You may simply decide that Albert Einstein’s a huge dick for never saying things that can be completely understood solely by scanning a headline. EPIC EINSTEIN FAIL, amirite? You never really know what you didn’t know until you know it But, Al just told the truth. Problem is, Al’s truth not only requires fancy things in order to be truly understood—the more of those fancy things you take away from his truth, the less true it gets. And, by the time it’s been diluted to the point where you're comfortable that you understand it? You'd be understanding the wrong thing. Even I can understand that. But, not one bit of any of this is Al’s fault. Al doesn’t get to control who uses, abuses, gets, or doesn’t get what he said or why it matters. Especially since he’s been dead for over fifty years. All I know is, regardless of who has ears to hear it on a given day, it would be to Al’s credit never to mangle something important in order to get it into terms everybody’s ready to handle without actually trying. And God bless him for never agreeing that your “distractions” to learning math are his problem. So, yeah, if you only need to hand in a crappy 5-page paper, you could certainly Cliff’s Notes your way through Borges, Eliot, or Joyce in an afternoon, and feel like you haven’t missed a thing. Trouble is, if you did care even a little, it’s impossible to even say how much you're missing since you can’t be bothered to soldier through the source text. The text itself is the entire point. Even the wonderfully cogent and readable layman’s explanations Einstein himself provided don’t really get to the nut, the application, and the implications of his real theory. That all takes real math. That “single datum of experience” matters Sometimes, complex or difficult things stop being true when you try to make them too simple. Sometimes, you have to actually get laid to understand why people think sex is such a thing. Sometimes, you need to learn some Greek if you really want to understand The Gospel of John. And, yeah, sometimes, you're going to have to just work unbelievably hard at whatever you claim to care about before anyone can begin to help you get any better—or less “distracted”—at it. The part I really know is what doesn’t work. Reading Penthouse Forum won’t help you CLEP out of Vaginal Intercourse 101. Watching a Rankin-Bass cartoon about the Easter Bunny will teach you very little about the intricacies of transubstantiation. And, if you can’t be troubled to care so much about your work that you reflexively force distractions away, dicking around with yet another writing application will merely aggravate the problem. Ironic, huh? These quantum mechanics of personal productivity are rife with such frustrating “paradoxes.” These are True Things. Achieving expertise and doing creative work is all horribly complicated and difficult and paradoxical and frustrating and recursive and James Joyce-y—and any guide, blog, binary, guru, or “nice guy” that tries to suggest otherwise is probably giving you a complimentary colonoscopy. Do the math. Want a new syllabus? Sure: Run straight into your shitstorm, my friends. Reject the impulse to think about work, rather than finishing it. And, open your heart to the remote possibility that any mythology of personal failure that involves messiahs periodically arriving to make everything “easy” for you might not really be helping your work or your mental health or your long-standing addiction to using tools solely to ship new excuses. Learn your real math, and any slide rule will suffice. Try, make, and do until you quit noticing the tools, and if you still think you need new tools, go try, make, and do more. If you can pull off this deceptively simple and millennia-old pattern, you'll eventually find that—god by dying god—any partial truth that’s supported your treasured excuses for not working will be replaced by a no-faith-required knowledge that you're really, actually, finally getting better at something you care about. Which is just sublimely un-distracting. Dedication This article is dedicated to my friend, Greg Knauss. No, he’s not the app guy–he’s just a good man who does good work, who accidentally/unintentionally helped me write this rant. He also happens to be a fella who could teach anyone a thing or two about writing with distractions.

In November this year, all eyes will be on Azerbaijan as Baku hosts the 29th UN Climate Conference (COP). Hosting COP offers an opportunity to push for climate action that reflects the host country’s unique circumstances, as well as regional interests. COP28 in the United Arab Emirates and COP27 in Egypt highlighted the climate priorities for the Middle East and North Africa (MENA), one of the world’s most vulnerable regions to the impacts of climate change.From rising temperatures and deadly heatwaves, to extreme weather events such as heavy rainstorms, sandstorms, and cyclones, climate change exacerbates existing vulnerabilities. These vulnerabilities include water scarcity, food security, and the preservation of livelihoods increasingly threatening the region’s social and economic stability.While there has been some progress in advancing formal negotiations on key issues, the gap between COP agreements and tangible actions to address the increasingly severe effects of climate change in the MENA region remains vast. This webinar aims to assess:What are the key tangible impacts of COP27 and COP28 in Egypt and the UAE respectively on driving climate action in the region?How do MENA countries balance COP28’s landmark agreement to transition away from fossil fuels with their unique national circumstances?How will the region benefit from COP28 breakthrough in integrating the issues of climate, peace and security in climate action through the ‘Declaration of Climate, Relief, Recovery and Peace’?What are the priorities for COP29 and how do they align with the climate agenda in the MENA region?

Counter-terrorism measures address broad forms of support to terrorist acts. Their expansion, internationally and domestically, has given rise to new points of friction with international humanitarian law. Unless the measures include adequate safeguards, they can impede humanitarian action. Country-specific sanctions imposed for other objectives, such as ending conflicts or protecting civilians, raise similar challenges for humanitarian action. These problems are not new, but solutions at international and national level remain elusive. At this panel event, which marks the launch of a new Chatham House research paper, panellists explore current endeavours to address the tensions between counter-terrorism measures, sanctions and humanitarian action.

When bound with cement, it becomes concrete; when mixed with bitumen, it becomes asphalt; and when heated, it becomes glass. According to a recent UN Environment Programme report, the world extracts over 40 billion tonnes of sand and aggregates every year. This is the equivalent of 18 kilograms per day per person – or enough to build a wall of sand 27 metres wide and 27 metres high around the entire globe each year. Sand extraction on this scale, particularly when taken from riverine or coastal locations, can have serious environmental impacts on ecosystems, biodiversity and erosion. Control of sand resources has also proved a source of tension between countries and violence within them. With demand for sand set to increase dramatically in line with population growth and urbanization, and with growing policy attention on the decarbonization of cement and other industrial inputs, better understanding of these impacts is needed. Yet with limited data on sand extraction, trade and consumption, and little in the way of governance frameworks, developing policies and practices that help ensure sustainable sand supply chains is challenging. This roundtable will examine the environmental, economic and political implications of sand supply chains and discuss opportunities to help integrate sustainable policy and practice. Full Article

action From local to global: A roadmap for US climate action By www.chathamhouse.org Published On :: Sun, 28 Mar 2021 15:50:49 +0000 From local to global: A roadmap for US climate action 14 April 2021 — 6:30PM TO 8:00PM Anonymous (not verified) 28 March 2021 Online Ahead of Biden’s Earth Day Summit, panellists discuss a range of climate issues, from city-level climate management to the international security implications of climate deals. On their first day in office, the Biden-Harris administration sent a strong message to Americans and allies by rejoining the Paris Agreement. Experienced climate and environmental leaders were appointed to senior leadership roles as part of a ‘whole of government approach’ to climate action. Although decisive action is welcomed by many Americans and international partners, the divided domestic perspectives on climate and a changed international landscape pose significant challenges. Ahead of the Earth Day Summit on April 22, an event hosted by Joe Biden to mark America’s formal return to global climate talks, panellists discuss a range of climate issues, from city-level climate management to the international security implications of climate deals. How will post-COVID domestic priorities and policy influence the international approach of the US to climate action? How will US policy, both foreign and domestic, need to respond to the security and geopolitical elements posed by climate change? What actions are needed during the upcoming Earth Day Summit for the US to establish credibility as a climate leader? What shape are key debates taking on US-China climate relations ahead of COP 26, and how might climate issues be approached in relation to wider geopolitical tensions? Full Article
action Prioritizing equity and justice in climate action By www.chathamhouse.org Published On :: Thu, 10 Jun 2021 13:45:31 +0000 Prioritizing equity and justice in climate action 30 June 2021 — 11:00AM TO 12:00PM Anonymous (not verified) 10 June 2021 Online London Climate Action Week event: Why understanding equity and justice is essential to the ability to meaningfully inform climate politics. Citizen-led climate activism is demonstrating the need to think about climate change ‘not just as a problem for science to solve’ but also as a problem of equity, human rights and justice. The disproportionate impacts of climate change on the poor and the marginalized across the world means that understanding equity and justice is essential for the ability to meaningfully inform climate politics. Excluding these issues risks ignoring, or intentionally omitting, the consequences of policies, tools and frameworks on those who are most likely to face the severe costs of any climate action or inaction. In a pivotal year for climate decision-making, this event explores the necessity of equity and justice in climate action and how the world can move the political conversation to one that is more inclusive. The speakers explore how communities themselves articulate the justice dimensions of climate change and how fairness can create a greener future for current and future generations. This event is being hosted as a part of Strengthening Climate Diplomacy, a series of events from Chatham House during London Climate Action Week 2021. Full Article
action Food system transformation: A blind spot for climate and biodiversity action? By www.chathamhouse.org Published On :: Wed, 05 Oct 2022 10:57:14 +0000 Food system transformation: A blind spot for climate and biodiversity action? 20 October 2022 — 12:00PM TO 1:00PM Anonymous (not verified) 5 October 2022 Chatham House and Online How can COP27 and COP15 accelerate the agenda for sustainable food systems and land use? Tackling the dual crises of climate change and biodiversity loss requires extraordinary levels of action at an unprecedented speed. Agriculture is the biggest user of land, the biggest source of methane emissions, a major contributor to total greenhouse gas emissions and the leading driver of biodiversity loss. Anything short of a food system transformation puts climate and biodiversity objectives in peril. However, governments have not yet produced credible pathways and strong policies for tackling our growing ‘foodprint’ – the negative impacts of what we grow and eat. In advance of COP27 in Sharm El-Sheikh for climate and COP15 in Montreal for biodiversity, Chatham House has published a new briefing paper which examines aligning food systems with climate and biodiversity targets. The paper reviews the climate and biodiversity policy landscape to 2030, with a focus on land-based aspects and the inclusion of food and agriculture. The paper highlights serious conflicts between the impacts of the food system and goals to protect and restore biodiversity and mitigate climate change. In light of this, opportunities for joined-up action on food, climate and biodiversity are identified, including three key steps for countries to take this decade to produce suitably ambitious and effective policies across the climate–biodiversity–food nexus. This event brings together leading voices from the international policy arenas for climate and biodiversity to react to the briefing paper and discuss how COP27 and COP15 can accelerate the agenda for sustainable food systems and land use.

action Representative cancer-associated U2AF2 mutations alter RNA interactions and splicing [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 High-throughput sequencing of hematologic malignancies and other cancers has revealed recurrent mis-sense mutations of genes encoding pre-mRNA splicing factors. The essential splicing factor U2AF2 recognizes a polypyrimidine-tract splice-site signal and initiates spliceosome assembly. Here, we investigate representative, acquired U2AF2 mutations, namely N196K or G301D amino acid substitutions associated with leukemia or solid tumors, respectively. We determined crystal structures of the wild-type (WT) compared with N196K- or G301D-substituted U2AF2 proteins, each bound to a prototypical AdML polypyrimidine tract, at 1.5, 1.4, or 1.7 Å resolutions. The N196K residue appears to stabilize the open conformation of U2AF2 with an inter-RNA recognition motif hydrogen bond, in agreement with an increased apparent RNA-binding affinity of the N196K-substituted protein. The G301D residue remains in a similar position as the WT residue, where unfavorable proximity to the RNA phosphodiester could explain the decreased RNA-binding affinity of the G301D-substituted protein. We found that expression of the G301D-substituted U2AF2 protein reduces splicing of a minigene transcript carrying prototypical splice sites. We further show that expression of either N196K- or G301D-substituted U2AF2 can subtly alter splicing of representative endogenous transcripts, despite the presence of endogenous, WT U2AF2 such as would be present in cancer cells. Altogether, our results demonstrate that acquired U2AF2 mutations such as N196K and G301D are capable of dysregulating gene expression for neoplastic transformation. Full Article
action Mapping the transition state for a binding reaction between ancient intrinsically disordered proteins [Molecular Biophysics] By www.jbc.org Published On :: 2020-12-18T00:06:18-08:00 Intrinsically disordered protein domains often have multiple binding partners. It is plausible that the strength of pairing with specific partners evolves from an initial low affinity to a higher affinity. However, little is known about the molecular changes in the binding mechanism that would facilitate such a transition. We previously showed that the interaction between two intrinsically disordered domains, NCBD and CID, likely emerged in an ancestral deuterostome organism as a low-affinity interaction that subsequently evolved into a higher-affinity interaction before the radiation of modern vertebrate groups. Here we map native contacts in the transition states of the low-affinity ancestral and high-affinity human NCBD/CID interactions. We show that the coupled binding and folding mechanism is overall similar but with a higher degree of native hydrophobic contact formation in the transition state of the ancestral complex and more heterogeneous transient interactions, including electrostatic pairings, and an increased disorder for the human complex. Adaptation to new binding partners may be facilitated by this ability to exploit multiple alternative transient interactions while retaining the overall binding and folding pathway. Full Article
action Determinants of replication protein A subunit interactions revealed using a phosphomimetic peptide [Molecular Biophysics] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Replication protein A (RPA) is a eukaryotic ssDNA-binding protein and contains three subunits: RPA70, RPA32, and RPA14. Phosphorylation of the N-terminal region of the RPA32 subunit plays an essential role in DNA metabolism in processes such as replication and damage response. Phosphorylated RPA32 (pRPA32) binds to RPA70 and possibly regulates the transient RPA70-Bloom syndrome helicase (BLM) interaction to inhibit DNA resection. However, the structural details and determinants of the phosphorylated RPA32–RPA70 interaction are still unknown. In this study, we provide molecular details of the interaction between RPA70 and a mimic of phosphorylated RPA32 (pmRPA32) using fluorescence polarization and NMR analysis. We show that the N-terminal domain of RPA70 (RPA70N) specifically participates in pmRPA32 binding, whereas the unphosphorylated RPA32 does not bind to RPA70N. Our NMR data revealed that RPA70N binds pmRPA32 using a basic cleft region. We also show that at least 6 negatively charged residues of pmRPA32 are required for RPA70N binding. By introducing alanine mutations into hydrophobic positions of pmRPA32, we found potential points of contact between RPA70N and the N-terminal half of pmRPA32. We used this information to guide docking simulations that suggest the orientation of pmRPA32 in complex with RPA70N. Our study demonstrates detailed features of the domain-domain interaction between RPA70 and RPA32 upon phosphorylation. This result provides insight into how phosphorylation tunes transient bindings between RPA and its partners in DNA resection. Full Article
action West Bank Annexation: International Rhetoric vs. Action By www.chathamhouse.org Published On :: Mon, 13 Jul 2020 16:30:48 +0000 14 July 2020 Reni Zhelyazkova Programme Coordinator, Middle East and North Africa Programme @renizhelyazkova Professor Yossi Mekelberg Senior Consulting Research Fellow, Middle East and North Africa Programme @YMekelberg Israel may have delayed announcing its plans to annex West Bank lands but the international community now needs to transform its rhetoric into action if there is to be a lasting solution to the Israel-Palestine conflict, argue Reni Zhelyazkova and Yossi Mekelberg. GettyImages-1223719050.jpg Houses are pictured in the Maale Adumim settlement in the West Bank east of Jerusalem. The Israeli government has delayed plans to annex Jewish settlements in the West Bank and in the Jordan Valley. Photo: Getty Images Observers of the Israel-Palestine conflict have been anticipating Israeli Prime Minister, Benjamin Netanyahu’s, announcement to annex parts of the West Bank. It has been a tumultuous year for Israeli politics which has seen three inconclusive elections and resulted in a sharing of power between Netanyahu and Benny Gantz of the Blue and White party. However, since the coalition government was sworn in, Netanyahu has appeared to not lose any time in moving forward with his plans.Annexation has long been Netanyahu’s political aspiration and was part of his recent re-election platform but the anticipated announcement from the Israeli government didn’t come straight away. The determining factor in the delay was the inability to reach an agreement with Washington about the scope of the annexation while divisions within the Israeli government itself, in addition to international condemnation from the region and beyond, has also played a part.Discussions around annexation have so far yielded one major outcome: it has introduced a different rhetoric by the Trump-Netanyahu axis even though things on the ground don’t necessarily follow. Ever since President Donald Trump took office in 2016, there has been a marked change in Washington’s language around the Israel-Palestine conflict. It has shifted towards legitimizing Israel’s expansionist ambitions in the West Bank while marginalizing, and considerably weakening, the Palestinian Authority (PA) through a series of punitive measures.This has further damaged relations between Israel and Palestine and has resulted in a fundamental change in the public discourse around the conflict, from emphasizing a just solution based on self-determination for both sides, to focusing on a de-facto one-state solution.But how has the discourse shifted so dramatically in less than four years? First came the announcement of the US embassy move to Jerusalem, and with it, recognition of the city as Israel’s capital. In his statement, President Trump avoided recognizing Palestinian claims over Jerusalem and did not acknowledge their historical connection with the city. When the PA rejected the move, the US administration then retaliated by cutting aid and development funding and closing the PLO mission in Washington stating: ‘We have permitted the PLO office to conduct operations that support the objective of achieving a lasting...peace between Israelis and the Palestinians … However, the PLO has not taken steps to advance the start of...meaningful negotiations with Israel.’ On the question of Israel’s settlements in the West Bank, the current US administration has shied away from calling them ‘illegal’ despite being deemed illegitimate under international law and condemned on numerous occasions by the UN Security Council, the UN General Assembly, the EU, the Arab League and the Palestinians themselves. US Secretary of State, Mike Pompeo, has even gone as far as saying that the establishment of Israeli settlements in the West Bank is not inconsistent with international law.The culmination of US discourse in recent months has been the unveiling of the ‘Peace to Prosperity’ plan. The language of the proposal, once again, has shown partiality towards Israel by not mentioning the illegality of Israel’s occupation of the West Bank, or that of settlements, and entirely ignoring previous Palestinian positions or acknowledging their sensitivities. There is little doubt that the current US administration understands the power of rhetoric and has been using it to change the trajectory of discussions away from a two-state solution towards an outcome that would only serve Israeli interests.Indeed, US rhetoric has empowered Netanyahu immensely too, ushering in a new reality that has rendered a Palestinian state nothing more than a hypothetical option. The language, combined with a multitude of unilateral actions, is helping to dismantle any efforts towards a two-state solution and the upholding of previous international agreements.Many European and regional governments have condemned any move towards annexation. Indeed, 1,000 European parliamentarians from across political lines have urged Israel to abandon its plans. This has notably included, German Foreign Minister, Heiko Mass, whose first overseas visit during the coronavirus crisis was to Israel to reinforce Germany’s position against unilateral action.But actions speak louder than words, and in the case of the US, its rhetoric has been matched by action unlike its EU counterparts whose statements of condemnation have rarely been followed by concrete action. For instance, the EU ratified a landmark aviation agreement with Israel just days before 1 July and economic, technological and scientific cooperation between Israel and Europe has never been stronger casting doubt on the strength of political will among EU countries to take action against Israel.In the Middle East, the United Arab Emirates has been the most vociferous in disapproving Israel’s annexation plans. However, again, it is important to look beyond the rhetoric. Cooperation between the UAE and Israel has in fact increased in recent years mainly due to common opposition to Iran’s regional influence but also due to shared interests. In May, for instance, the first publicly acknowledged commercial flight between the UAE and Israel landed at Ben Gurion airport carrying aid aimed at mitigating the effects of COVID-19 in the Palestinian territories. But, to many, it looked like a stepping-stone towards a normalization of relations between Abu Dhabi and Jerusalem.Similarly, Jordan and Egypt have also expressed their concern but it is difficult to imagine a scenario where either country would go as far as abrogating peace agreements that they currently have in place with Israel.In spite of this, the global response has overwhelmingly been critical of Israel’s plans to annex parts of the West Bank. This has demonstrated some level of unity among world leaders which has not been seen for some time and may have played a significant role in delaying the Israeli government’s plans. In parallel, united international condemnation has also prevented the US from dominating the Israeli-Palestinian conflict entirely.While the US approach has played a key role in the Israel-Palestine conflict so far, it remains to be seen how the international community will translate its voice into action to prevent the annexation of occupied Palestinian land.

action Coronavirus infection and PARP expression dysregulate the NAD metabolome: An actionable component of innate immunity [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-25T00:06:30-08:00 Poly(ADP-ribose) polymerase (PARP) superfamily members covalently link either a single ADP-ribose (ADPR) or a chain of ADPR units to proteins using NAD as the source of ADPR. Although the well-known poly(ADP-ribosylating) (PARylating) PARPs primarily function in the DNA damage response, many noncanonical mono(ADP-ribosylating) (MARylating) PARPs are associated with cellular antiviral responses. We recently demonstrated robust up-regulation of several PARPs following infection with murine hepatitis virus (MHV), a model coronavirus. Here we show that SARS-CoV-2 infection strikingly up-regulates MARylating PARPs and induces the expression of genes encoding enzymes for salvage NAD synthesis from nicotinamide (NAM) and nicotinamide riboside (NR), while down-regulating other NAD biosynthetic pathways. We show that overexpression of PARP10 is sufficient to depress cellular NAD and that the activities of the transcriptionally induced enzymes PARP7, PARP10, PARP12 and PARP14 are limited by cellular NAD and can be enhanced by pharmacological activation of NAD synthesis. We further demonstrate that infection with MHV induces a severe attack on host cell NAD+ and NADP+. Finally, we show that NAMPT activation, NAM, and NR dramatically decrease the replication of an MHV that is sensitive to PARP activity. These data suggest that the antiviral activities of noncanonical PARP isozyme activities are limited by the availability of NAD and that nutritional and pharmacological interventions to enhance NAD levels may boost innate immunity to coronaviruses.

action A Gs-RhoGEF interaction: An old G protein finds a new job [Cell Biology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 The heterotrimeric G proteins are known to have a variety of downstream effectors, but Gs was long thought to be specifically coupled to adenylyl cyclases. A new study indicates that activated Gs can also directly interact with a guanine nucleotide exchange factor for Rho family small GTPases, PDZ-RhoGEF. This novel interaction mediates activation of the small G protein Cdc42 by Gs-coupled GPCRs, inducing cytoskeletal rearrangements and formation of filopodia-like structures. Furthermore, overexpression of a minimal PDZ-RhoGEF fragment can down-regulate cAMP signaling, suggesting that this effector competes with canonical signaling. This first demonstration that the Gαs subfamily regulates activity of Rho GTPases extends our understanding of Gαs activity and establishes RhoGEF coupling as a universal Gα function. Full Article
action Interrogation of kinase genetic interactions provides a global view of PAK1-mediated signal transduction pathways [Gene Regulation] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 Kinases are critical components of intracellular signaling pathways and have been extensively investigated with regard to their roles in cancer. p21-activated kinase-1 (PAK1) is a serine/threonine kinase that has been previously implicated in numerous biological processes, such as cell migration, cell cycle progression, cell motility, invasion, and angiogenesis, in glioma and other cancers. However, the signaling network linked to PAK1 is not fully defined. We previously reported a large-scale yeast genetic interaction screen using toxicity as a readout to identify candidate PAK1 genetic interactions. En masse transformation of the PAK1 gene into 4,653 homozygous diploid Saccharomyces cerevisiae yeast deletion mutants identified ∼400 candidates that suppressed yeast toxicity. Here we selected 19 candidate PAK1 genetic interactions that had human orthologs and were expressed in glioma for further examination in mammalian cells, brain slice cultures, and orthotopic glioma models. RNAi and pharmacological inhibition of potential PAK1 interactors confirmed that DPP4, KIF11, mTOR, PKM2, SGPP1, TTK, and YWHAE regulate PAK1-induced cell migration and revealed the importance of genes related to the mitotic spindle, proteolysis, autophagy, and metabolism in PAK1-mediated glioma cell migration, drug resistance, and proliferation. AKT1 was further identified as a downstream mediator of the PAK1-TTK genetic interaction. Taken together, these data provide a global view of PAK1-mediated signal transduction pathways and point to potential new drug targets for glioma therapy. Full Article
action HIV-1 Gag release from yeast reveals ESCRT interaction with the Gag N-terminal protein region [Molecular Bases of Disease] By www.jbc.org Published On :: 2020-12-25T00:06:30-08:00 The HIV-1 protein Gag assembles at the plasma membrane and drives virion budding, assisted by the cellular endosomal complex required for transport (ESCRT) proteins. Two ESCRT proteins, TSG101 and ALIX, bind to the Gag C-terminal p6 peptide. TSG101 binding is important for efficient HIV-1 release, but how ESCRTs contribute to the budding process and how their activity is coordinated with Gag assembly is poorly understood. Yeast, allowing genetic manipulation that is not easily available in human cells, has been used to characterize the cellular ESCRT function. Previous work reported Gag budding from yeast spheroplasts, but Gag release was ESCRT-independent. We developed a yeast model for ESCRT-dependent Gag release. We combined yeast genetics and Gag mutational analysis with Gag-ESCRT binding studies and the characterization of Gag-plasma membrane binding and Gag release. With our system, we identified a previously unknown interaction between ESCRT proteins and the Gag N-terminal protein region. Mutations in the Gag-plasma membrane–binding matrix domain that reduced Gag-ESCRT binding increased Gag-plasma membrane binding and Gag release. ESCRT knockout mutants showed that the release enhancement was an ESCRT-dependent effect. Similarly, matrix mutation enhanced Gag release from human HEK293 cells. Release enhancement partly depended on ALIX binding to p6, although binding site mutation did not impair WT Gag release. Accordingly, the relative affinity for matrix compared with p6 in GST-pulldown experiments was higher for ALIX than for TSG101. We suggest that a transient matrix-ESCRT interaction is replaced when Gag binds to the plasma membrane. This step may activate ESCRT proteins and thereby coordinate ESCRT function with virion assembly. Full Article

action Human glucocerebrosidase mediates formation of xylosyl-cholesterol by {beta}-xylosidase and transxylosidase reactions. [Research Articles] By www.jlr.org Published On :: 2020-12-23T13:30:20-08:00 Deficiency of glucocerebrosidase (GBA), a lysosomal β-glucosidase, causes Gaucher disease. The enzyme hydrolyzes β-glucosidic substrates and transglucosylates cholesterol to cholesterol-β-glucoside. Here we show that recombinant human GBA also cleaves β-xylosides and transxylosylates cholesterol. The xylosyl-cholesterol formed acts as acceptor for subsequent formation of di-xylosyl-cholesterol. Common mutant forms of GBA from patients with Gaucher disease with reduced β-glucosidase activity were similarly impaired in β-xylosidase, transglucosidase and transxylosidase activities, except for a slightly reduced xylosidase/glucosidase activity ratio of N370S GBA and a slightly reduced transglucosylation/glucosidase activity ratio of D409H GBA. XylChol was found to be reduced in spleen from Gaucher disease patients. The origin of newly identified XylChol in mouse and human tissues was investigated. Cultured human cells exposed to exogenous β-xylosides generated XylChol in a manner dependent on active lysosomal GBA but not the cytosol-facing β-glucosidase GBA2. We later sought an endogenous β-xyloside acting as donor in transxylosylation reactions, identifying xylosylated ceramide (XylCer) in cells and tissues that serve as donor in the formation of XylChol. UDP-glucosylceramide synthase (GCS) was unable to synthesize XylChol but could catalyse formation of XylCer. Thus, food-derived β-D-xyloside and XylCer are potential donors for the GBA-mediated formation of XylChol in cells. The enzyme GCS produces XylCer at a low rate. Our findings point to further catalytic versatility of GBA and prompt a systematic exploration of the distribution and role of xylosylated lipids. Full Article
action An Interaction Network of RNA-Binding Proteins Involved in Drosophila Oogenesis [Research] By www.mcponline.org Published On :: 2020-09-01T00:05:24-07:00 During Drosophila oogenesis, the localization and translational regulation of maternal transcripts relies on RNA-binding proteins (RBPs). Many of these RBPs localize several mRNAs and may have additional direct interaction partners to regulate their functions. Using immunoprecipitation from whole Drosophila ovaries coupled to mass spectrometry, we examined protein-protein associations of 6 GFP-tagged RBPs expressed at physiological levels. Analysis of the interaction network and further validation in human cells allowed us to identify 26 previously unknown associations, besides recovering several well characterized interactions. We identified interactions between RBPs and several splicing factors, providing links between nuclear and cytoplasmic events of mRNA regulation. Additionally, components of the translational and RNA decay machineries were selectively co-purified with some baits, suggesting a mechanism for how RBPs may regulate maternal transcripts. Given the evolutionary conservation of the studied RBPs, the interaction network presented here provides the foundation for future functional and structural studies of mRNA localization across metazoans.

action Differential Complex Formation via Paralogs in the Human Sin3 Protein Interaction Network [Research] By www.mcponline.org Published On :: 2020-09-01T00:05:24-07:00 Despite the continued analysis of HDAC inhibitors in clinical trials, the heterogeneous nature of the protein complexes they target limits our understanding of the beneficial and off-target effects associated with their application. Among the many HDAC protein complexes found within the cell, Sin3 complexes are conserved from yeast to humans and likely play important roles as regulators of transcriptional activity. The presence of two Sin3 paralogs in humans, SIN3A and SIN3B, may result in a heterogeneous population of Sin3 complexes and contributes to our poor understanding of the functional attributes of these complexes. Here, we profile the interaction networks of SIN3A and SIN3B to gain insight into complex composition and organization. In accordance with existing data, we show that Sin3 paralog identity influences complex composition. Additionally, chemical cross-linking MS identifies domains that mediate interactions between Sin3 proteins and binding partners. The characterization of rare SIN3B proteoforms provides additional evidence for the existence of conserved and divergent elements within human Sin3 proteins. Together, these findings shed light on both the shared and divergent properties of human Sin3 proteins and highlight the heterogeneous nature of the complexes they organize. Full Article
