ESO instrument finds closest black hole to Earth

(ESO) Astronomers have discovered a black hole lying just 1,000 light-years from Earth. The black hole is closer to our solar system than any other found to date and forms part of a triple system that can be seen with the naked eye. The astronomers found evidence for the invisible object by tracking its two companion stars using the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile. They say this system could just be the tip of the iceberg.

Trump’s Threat to Target Iran’s Cultural Heritage Is Illegal and Wrong

7 January 2020

Targeting cultural property is rightly prohibited under the 1954 Hague Convention.

As tensions escalate in the Middle East, US President Donald Trump has threatened to strike targets in Iran should they seek to retaliate over the killing of Qassem Soleimani. According to the president’s tweet, these sites includes those that are ‘important to Iran and Iranian culture’.

Defense Secretary Mark Esper was quick on Monday to rule out any such action and acknowledged that the US would ‘follow the laws of armed conflict’. But Trump has not since commented further on the matter.

Any move to target Iranian cultural heritage could constitute a breach of the international laws protecting cultural property. Attacks on cultural sites are deemed unlawful under two United Nations conventions; the 1954 Hague Convention for the Protection of Cultural Property during Armed Conflict, and the 1972 UNESCO World Heritage Convention for the Protection of the World Cultural and Natural Heritage.

These have established deliberate attacks on cultural heritage (when not militarily necessary) as a war crime under the Rome Statute of the International Criminal Court in recognition of the irreparable damage that the loss of cultural heritage can have locally, regionally and globally.

These conventions were established in the aftermath of the Second World War, in reaction to the legacy of the massive destruction of cultural property that took place, including the intense bombing of cities, and systematic plunder of artworks across Europe. The conventions recognize that damage to the cultural property of any people means ‘damage to the cultural heritage of all mankind’. The intention of these is to establish a new norm whereby protecting culture and history – that includes cultural and historical property – is as important as safeguarding people.

Such historical sites are important not simply as a matter of buildings and statues, but rather for their symbolic significance in a people’s history and identity. Destroying cultural artefacts is a direct attack on the identity of the population that values them, erasing their memories and historical legacy. Following the heavy bombing of Dresden during the Second World War, one resident summed up the psychological impact of such destruction in observing that ‘you expect people to die, but you don’t expect the buildings to die’.

Targeting sites of cultural significance isn’t just an act of intimidation during conflict. It can also have a lasting effect far beyond the cessation of violence, hampering post-conflict reconciliation and reconstruction, where ruins or the absence of previously significant cultural monuments act as a lasting physical reminder of hostilities.

For example, during the Bosnian War in the 1990s, the Old Bridge in Mostar represented a symbol of centuries of shared cultural heritage and peaceful co-existence between the Serbian and Croat communities. The bridge’s destruction in 1993 at the height of the civil war and the temporary cable bridge which took its place acted as a lasting reminder of the bitter hostilities, prompting its reconstruction a decade later as a mark of the reunification of the ethnically divided town.

More recently, the destruction of cultural property has been a feature of terrorist organizations, such as the Taliban’s demolition of the 1,700-year-old Buddhas of Bamiyan in 2001, eliciting international condemnation. Similarly, in Iraq in 2014 following ISIS’s seizure of the city of Mosul, the terrorist group set about systematically destroying a number of cultural sites, including the Great Mosque of al-Nuri with its leaning minaret, which had stood since 1172. And in Syria, the ancient city of Palmyra was destroyed by ISIS in 2015, who attacked its archaeological sites with bulldozers and explosives.

Such violations go beyond destruction: they include the looting of archaeological sites and trafficking of cultural objects, which are used to finance terrorist activities, which are also prohibited under the 1954 Hague Convention.

As a war crime, the destruction of cultural property has been successfully prosecuted in the International Criminal Court, which sentenced Ahmad Al-Faqi Al-Mahdi to nine years in jail in 2016 for his part in the destruction of the Timbuktu mausoleums in Mali. Mahdi led members of Al-Qaeda in the Islamic Maghreb to destroy mausoleums and monuments of cultural and religious importance in Timbuktu, irreversibly erasing what the chief prosecutor described as ‘the embodiment of Malian history captured in tangible form from an era long gone’.

Targeting cultural property is prohibited under customary international humanitarian law, not only by the Hague Convention. But the Convention sets out detailed regulations for protection of such property, and it has taken some states a lot of time to provide for these.

Although the UK was an original signatory to the 1954 Hague Convention, it did not ratify it until 2017, introducing into law the Cultural Property (Armed Conflicts) Act 2017, and setting up the Cultural Protection Fund to safeguard heritage of international importance threatened by conflict in countries across the Middle East and North Africa.

Ostensibly, the UK’s delay in ratifying the convention lay in concerns over the definition of key terms and adequate criminal sanctions, which were addressed in the Second Protocol in 1999. However, changing social attitudes towards the plunder of antiquities, and an alarming increase in the use of cultural destruction as a weapon of war by extremist groups to eliminate cultures that do not align with their own ideology, eventually compelled the UK to act.

In the US, it is notoriously difficult to get the necessary majority for the approval of any treaty in the Senate; for the Hague Convention, approval was achieved in 2008, following which the US ratified the Convention in 2009.

Destroying the buildings and monuments which form the common heritage of humanity is to wipe out the physical record of who we are. People are people within a place, and they draw meaning about who they are from their surroundings. Religious buildings, historical sites, works of art, monuments and historic artefacts all tell the story of who we are and how we got here. We have a responsibility to protect them.

Multi-omic Characterization of the Mode of Action of a Potent New Antimalarial Compound, JPC-3210, Against Plasmodium falciparum [Research]

The increasing incidence of antimalarial drug resistance to the first-line artemisinin combination therapies underpins an urgent need for new antimalarial drugs, ideally with a novel mode of action. The recently developed 2-aminomethylphenol, JPC-3210, (MMV 892646) is an erythrocytic schizonticide with potent in vitro antimalarial activity against multidrug-resistant Plasmodium falciparum lines, low cytotoxicity, potent in vivo efficacy against murine malaria, and favorable preclinical pharmacokinetics including a lengthy plasma elimination half-life. To investigate the impact of JPC-3210 on biochemical pathways within P. falciparum-infected red blood cells, we have applied a "multi-omics" workflow based on high resolution orbitrap mass spectrometry combined with biochemical approaches. Metabolomics, peptidomics and hemoglobin fractionation analyses revealed a perturbation in hemoglobin metabolism following JPC-3210 exposure. The metabolomics data demonstrated a specific depletion of short hemoglobin-derived peptides, peptidomics analysis revealed a depletion of longer hemoglobin-derived peptides, and the hemoglobin fractionation assay demonstrated decreases in hemoglobin, heme and hemozoin levels. To further elucidate the mechanism responsible for inhibition of hemoglobin metabolism, we used in vitro β-hematin polymerization assays and showed JPC-3210 to be an intermediate inhibitor of β-hematin polymerization, about 10-fold less potent then the quinoline antimalarials, such as chloroquine and mefloquine. Further, quantitative proteomics analysis showed that JPC-3210 treatment results in a distinct proteomic signature compared with other known antimalarials. While JPC-3210 clustered closely with mefloquine in the metabolomics and proteomics analyses, a key differentiating signature for JPC-3210 was the significant enrichment of parasite proteins involved in regulation of translation. These studies revealed that the mode of action for JPC-3210 involves inhibition of the hemoglobin digestion pathway and elevation of regulators of protein translation. Importantly, JPC-3210 demonstrated rapid parasite killing kinetics compared with other quinolones, suggesting that JPC-3210 warrants further investigation as a potentially long acting partner drug for malaria treatment.

Large-scale Identification of N-linked Intact Glycopeptides in Human Serum using HILIC Enrichment and Spectral Library Search [Research]

Large-scale identification of N-linked intact glycopeptides by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) in human serum is challenging because of the wide dynamic range of serum protein abundances, the lack of a complete serum N-glycan database and the existence of proteoforms. In this regard, a spectral library search method was presented for the identification of N-linked intact glycopeptides from N-linked glycoproteins in human serum with target-decoy and motif-specific false discovery rate (FDR) control. Serum proteins were firstly separated into low-abundance and high-abundance proteins by acetonitrile (ACN) precipitation. After digestion, the N-linked intact glycopeptides were enriched by hydrophilic interaction liquid chromatography (HILIC) and a portion of the enriched N-linked intact glycopeptides were processed by Peptide-N-Glycosidase F (PNGase F) to generate N-linked deglycopeptides. Both N-linked intact glycopeptides and deglycopeptides were analyzed by LC-MS/MS. From N-linked deglycopeptides data sets, 764 N-linked glycoproteins, 1699 N-linked glycosites and 3328 unique N-linked deglycopeptides were identified. Four types of N-linked glycosylation motifs (NXS/T/C/V, X=P) were used to recognize the N-linked deglycopeptides. The spectra of these N-linked deglycopeptides were utilized for N-linked deglycopeptides library construction and identification of N-linked intact glycopeptides. A database containing 739 N-glycan masses was constructed and utilized during spectral library search for the identification of N-linked intact glycopeptides. In total, 526 N-linked glycoproteins, 1036 N-linked glycosites, 22,677 N-linked intact glycopeptides and 738 N-glycan masses were identified under 1% FDR, representing the most in-depth serum N-glycoproteome identified by LC-MS/MS at N-linked intact glycopeptide level.

Serum non-esterified fatty acids have utility as dietary biomarkers of fat intake from fish, fish oil and dairy in women [Methods]

Nutritional studies rely on various biological specimens for fatty acid (FA) determination, yet it is unclear how levels of serum non-esterified FA (NEFAs) correlate with other circulating lipid pools. Here, we used a high throughput method (< 4 min/sample) based on multisegment injection-non-aqueous-capillary electrophoresis–mass spectrometry (MSI-NACE-MS) to investigate whether specific serum NEFAs have utility as biomarkers of dietary fat intake in women. We first  identified circulating NEFAs correlated with long-term/habitual food intake among pregnant women with contrasting dietary patterns (n=50). Acute changes in serum NEFA trajectories were also studied in non-pregnant women (n=18) following high-dose (5 g/day) fish oil (FO) supplementation or isoenergetic sunflower oil placebo over 56 days. In the cross-sectional study, serum omega-3 (-3) FA correlated with self-reported total -3 daily intake, notably eicosapentaenoic acid (EPA) as its NEFA (r=0.46; p=0.001), whereas pentadecanoic acid was associated with full-fat dairy intake (r=0.43; p=0.002), outcomes consistent with results from  total FA serum hydrolysates. In the intervention cohort, serum -3 NEFAs increased 2.5-fold from baseline within 28 days following FO supplementation, and this increase was most pronounced for EPA (p=0.0004). Unlike for docosahexaenoic acid, circulating EPA as its NEFA also strongly correlated to EPA concentrations measured from erythrocyte phospholipid hydrolysates (r=0.66; p=4.6 x 10-10), and was better suited to detect dietary non-adherence. We conclude that MSI-NACE-MS offers a rapid method to quantify serum NEFAs and objectively monitor dietary fat intake in women that is complementary to diet records or food frequency questionnaires.

Acquiring and Analyzing Data Independent Acquisition Proteomics Experiments without Spectrum Libraries [Perspective]

Data independent acquisition (DIA) is an attractive alternative to standard shotgun proteomics methods for quantitative experiments. However, most DIA methods require collecting exhaustive, sample-specific spectrum libraries with data dependent acquisition (DDA) to detect and quantify peptides. In addition to working with non-human samples, studies of splice junctions, sequence variants, or simply working with small sample yields can make developing DDA-based spectrum libraries impractical. Here we illustrate how to acquire, queue, and validate DIA data without spectrum libraries, and provide a workflow to efficiently generate DIA-only chromatogram libraries using gas-phase fractionation (GPF). We present best-practice methods for collecting DIA data using Orbitrap-based instruments, and develop an understanding for why DIA using an Orbitrap mass spectrometer should be approached differently than when using time-of-flight instruments. Finally, we discuss several methods for analyzing DIA data without libraries.

Russian Policy on Iran: Trump and Trap

1 February 2007 , Number 1

Russia is playing a risky game in Iran, continuing to build a nuclear power plant while supporting United Nations sanctions on Tehran for its nuclear policy. Moscow may be hoping for a deal with the west, but if restraint fails and Iran goes nuclear, the missiles would be too close for comfort. Equally a pre-emptive American or Israeli strike on Iranian nuclear sites might unleash serious consequences for Russia too.

Serum amyloid A is not incorporated into HDL during HDL biogenesis [Research Articles]

Liver-derived serum amyloid A (SAA) is present in plasma where it is mainly associated with HDL and from which it is cleared more rapidly than are the other major HDL-associated apolipoproteins. Although evidence suggests that lipid-free and HDL-associated forms of SAA have different activities, the pathways by which SAA associates and disassociates with HDL are poorly understood. In this study, we investigated SAA lipidation by hepatocytes and how this lipidation relates to the formation of nascent HDL particles. We also examined hepatocyte-mediated clearance of lipid-free and HDL-associated SAA. We prepared hepatocytes from mice injected with lipopolysaccharide or an SAA-expressing adenoviral vector. Alternatively, we incubated primary hepatocytes from SAA-deficient mice with purified SAA. We analyzed conditioned media to determine the lipidation status of endogenously produced and exogenously added SAA. Examining the migration of lipidated species, we found that SAA is lipidated and forms nascent particles that are distinct from apoA-I-containing particles and that apoA-I lipidation is unaltered when SAA is overexpressed or added to the cells, indicating that SAA is not incorporated into apoA-I-containing HDL during HDL biogenesis. Like apoA-I formation, generation of SAA-containing particles was dependent on ABCA1, but not on scavenger receptor class B type I. Hepatocytes degraded significantly more SAA than apoA-I. Taken together, our results indicate that SAA’s lipidation and metabolism by the liver is independent of apoA-I and that SAA is not incorporated into HDL during HDL biogenesis.

An LC/MS/MS method for analyzing the steroid metabolome with high accuracy and from small serum samples [Methods]

Analyzing global steroid metabolism in humans can shed light on the etiologies of steroid-related diseases. However, existing methods require large amounts of serum and lack the evaluation of accuracy. Here, we developed an LC/MS/MS method for the simultaneous quantification of 12 steroid hormones: testosterone, pregnenolone, progesterone, androstenedione, corticosterone, 11-deoxycortisol, cortisol, 17-hydroxypregnenolone, 17-hydroxyprogesterone, dehydroepiandrosterone, estriol, and estradiol. Steroids and spiked internal standards in 100 μl serum were extracted by protein precipitation and liquid-liquid extraction. The organic phase was dried by evaporation, and isonicotinoyl chloride was added for steroid derivatization, followed by evaporation under nitrogen and redissolution in 50% methanol. Chromatographic separation was performed on a reverse-phase PFP column, and analytes were detected on a triple quadrupole mass spectrometer with ESI. The lower limits of quantification ranged from 0.005 ng/ml for estradiol to 1 ng/ml for cortisol. Apparent recoveries of steroids at high, medium, and low concentrations in quality control samples were between 86.4% and 115.0%. There were limited biases (–10.7% to 10.5%) between the measured values and the authentic values, indicating that the method has excellent reliability. An analysis of the steroid metabolome in pregnant women highlighted the applicability of the method in clinical serum samples. We conclude that the LC/MS/MS method reported here enables steroid metabolome analysis with high accuracy and reduced serum consumption, indicating that it may be a useful tool in both clinical and scientific laboratory research.

Longitudinal Analysis of Serum Cytokine Levels and Gut Microbial Abundance Links IL-17/IL-22 with Clostridia and Insulin Sensitivity in Humans

Recent studies using mouse models suggest that interaction between the gut microbiome and IL-17/IL-22 producing cells plays a role in the development of metabolic diseases. We investigated this relationship in humans using data from the prediabetes study of the Integrated Human Microbiome Project (iHMP). Specifically, we addressed the hypothesis that early in the onset of metabolic diseases there is a decline in serum levels of IL-17/IL-22, with concomitant changes in the gut microbiome. Clustering iHMP study participants on the basis of longitudinal IL-17/IL-22 profiles identified discrete groups. Individuals distinguished by low levels of IL-17/IL-22 were linked to established markers of metabolic disease, including insulin sensitivity. These individuals also displayed gut microbiome dysbiosis, characterized by decreased diversity, and IL-17/IL-22-related declines in the phylum Firmicutes, class Clostridia, and order Clostridiales. This ancillary analysis of the iHMP data therefore supports a link between the gut microbiome, IL-17/IL-22 and the onset of metabolic diseases. This raises the possibility for novel, microbiome-related therapeutic targets that may effectively alleviate metabolic diseases in humans as they do in animal models.

Plaintiff in Chief: President Trump and the American Legal System

James D Zirin, Host, Conversations with Jim Zirin; Author, Plaintiff in Chief: A Portrait of Donald Trump in 3500 Lawsuits

Chair: Chanu Peiris, Programme Manager, International Law Programme, Chatham House

Since assuming office, President Donald Trump’s many encounters with litigation have exposed significant irregularities of the American legal system as it applies to the president.

These encounters – including but not limited to accusations of defamation, obstruction, perjury and non-disclosure agreements – have shown President Trump to hold a particular interpretation of how the rule of law should apply to someone holding the highest elected office in the United States of America.

However, an analysis of Trump’s legal history prior to his assumption of office reveals a tried and tested method of using litigation – or the threat of it – to quieten criticism and opponents. As Trump faces possible impeachment in the House of Representatives, what – if any – influence might his combative approach towards legal battles have on the political proceedings?

Drawing on New York attorney James Zirin’s new book, Plaintiff in Chief, this event examines the relationship between President Trump’s litigation history and his approach to the presidency.

How has the American legal system facilitated Trump’s attitude towards litigation? How can his litigation toolkit be countered?

And what impact has the president’s approach to litigation had on the domestic and global reputation of the American legal system and the office of the president as accountable and credible institutions?

Partisanship Meets Trump’s Impeachment

19 December 2019

Dr Lindsay Newman

Senior Research Fellow, US and the Americas Programme
History shows that if those pushing for impeachment and removal want to succeed, they need to drive up popular support for a senate conviction.

The vote to impeach Donald Trump holds almost no surprises - on both the abuse of power and obstruction of congress articles, the votes were split entirely on party lines with nearly all the majority-led House Democrats but not a single Republican voting to impeach Trump.

However, this ‘pre-ordained’ outcome of the House impeachment inquiry does serve to highlight that the US is in the midst of a hyper-partisan political moment. Policy gridlock has led to two government shutdowns during Donald Trump’s presidency, with one further budgetary fight narrowly avoided.

With a few notable exceptions (such as USMCA), policy areas that lend themselves to bipartisanship - including infrastructure and drug pricing - have seen very little progress under divided congressional chambers. Party identification can now be overlaid with the cable news channel one watches or the newspaper one reads.

Impeachment now moves to the Senate for a trial, requiring a two-thirds majority of the Republican-led senate (or 67 senators) for a conviction. Given the congressional partisanship we are seeing, the baseline scenario continues to be that the senate will not vote to convict Trump and remove him from office - despite much being made of how many senators are likely to vote for a Senate conviction.

Why public opinion could be crucial

There is another story to keep a close eye on. The number to track is 47.2 – the current polling average of public support for Trump’s impeachment. Polling averages from the end of September 2019 (before the hearings began, but after House Speaker Nancy Pelosi announced a formal inquiry) had 49.4% supporting impeachment versus 47.2% this week.

Here’s why this number matters. If those pushing for impeachment and removal are unable to drive popular support across a critical threshold level, then those against impeachment and removal are not going to abandon the president and vote for a senate conviction. With Trump consistently polling in the low 40s on job approval, but in the high 80s/low 90s within the Republican party, this means Republican congress members concerned about re-election are extremely hesitant to distance themselves from him without a clear mandate from the domestic public. 

A tale of the two most recent presidents to face impeachment underscores this point. Gallup polling claimed 58% of adults supported impeaching and removing President Richard Nixon from office in August 1974, whereas only 35% of the public supported impeaching President Bill Clinton in December 1998, the month he was impeached.

Given the respective outcomes of those two impeachments, it suggests public support for impeachment and removal needs to increase well beyond the current 47.2%, to avoid the foregone conclusion of acquittal in the Senate (even if there are signs of the tide moving in the opposite direction with those against impeachment overtaking support for the first time in December).   

What does this mean for Democrats?

In the short term, if the Democrats want to make inroads into the hearts and minds of those across the partisan gulf, it will be critical to secure senate testimony from those in Trump’s inner circle at the time of the Ukrainian affair.

After Trump ordered individuals with first-hand knowledge of the administration’s efforts vis-à-vis Ukraine not to testify, House investigators were unable to call many witnesses with direct evidence (which in fact left the House testimony exposed to Republican claims of hearsay). With Trump impeached, more of the public is likely to tune in to the senate proceedings, and direct evidence by inner circle administration officials required to testify presents an opportunity to move public opinion.

House speaker Nancy Pelosi recognizes how crucial the procedures and participants for the senate trial will be, and has said she could delay sending the articles of impeachment to the senate as leverage for a 'fair trial'.

Democrats also have to consider how an impeachment inquiry that - at least from this vantage point - does not end in a conviction of the president plays out for the 2020 election campaign, especially if this also likely means that public opinion - and certainly Republican-party views - of Trump have not shifted.

Iran Crisis: How Far Does Trump’s Authority Go?

The legal and political boundaries of presidential power are being redefined, but the president may still be attentive to some constraints.

2020-01-10-Trump.jpg

On Thursday, the US House of Representatives passed a resolution affirming its authority under the War Powers Resolution Act, and reminding the president, the American people and the world that when it comes to the use of military force, Congress must be taken into account. 

President Donald Trump replied by retweeting John Bolton, his former national security advisor, who tweeted that the War Powers Act was ‘unconstitutional’, effectively dismissing Congressional efforts to rein in the president.

This round of legal Twitter diplomacy came days after the president tweeted that ‘legal notice (to Congress) is not required, but it is given nevertheless’ and that ‘should Iran strike any US person or target, the United States will quickly and fully strike back, and perhaps in a disproportionate manner.’ 

President Trump’s overt attacks on Congressional authority and disregard for the law are not normal for a US president, but legal constraints over the president’s authority to use military force have been eroding for several years.

In 1973, Congress passed the War Powers Act, requiring the president to report to Congress and acquire Congressional approval for continued overseas troop deployments. But Congressional authority over the use of military force has continued to diminish, especially since the 9/11 attacks. 

Now, Congress is pushing back – a resolution similar to that passed by the House is likely to be voted on by the Senate soon. Given the intense frustration of some senators over the president’s handling of the current conflict, this resolution may pass, though the president is still likely to veto. 

The bigger problem, of which this is one part, is the expansion of executive authority, and it predates this presidency. Many argue that executive power is greatest on matters of foreign policy, and that in this domain the US president is unconstrained. As partisanship has increased and the demands on Congress have made it harder for its members to cultivate foreign policy expertise, the power of the president has grown.

So the fact that Congress is taking active steps to check the president’s power not only on the question of impeachment, but also on foreign policy, is significant, even if the law is not likely to restrain President Trump. But Congress is also playing a long game. And its growing determination to assert its authority matters not only for this presidency, but also for the future.

Political constraints

In the short term, other constraints matter more. Even if President Trump rejects legal restraints – and shuns diplomatic pressure that might have mattered to other presidents – he is not impervious to political restraint.

Already there are signs that Trump listens to his key Republican allies in Congress. When Senator Lindsay Graham pushed back against the president’s threat to attack cultural heritage sites in Iran, and the Pentagon failed to shore up the president’s threat, the president changed his position. The threats also provoked an overwhelming response in Europe, and across the Middle East, but the president has shown that he is willing to disregard international admonishment. Not so for domestic allies.

Nor is this the first time that Senator Graham’s views have mattered. When the president announced his decision to pull troops from northeast Syria, effectively abandoning the Kurds, a key partner to the US in its fight against ISIS, Senator Graham and Senator Mitch McConnell pushed back and it mattered. 

Public opinion also matters to the president, especially Republican public opinion, and this is likely to affect the president’s next steps. Recent polls suggest that Americans feel less safe as a result of the killing of General Qassem Soleimani by a considerable margin of 55% to 24%.

But the same survey also shows that a majority of Americans support the decision to kill Soleimani. Already Vice President Mike Pence has spoken at a rally in Ohio designed to bolster support for this Presidential action.  

So what might change public opinion and will this alter the president’s future steps?

Americans are very reluctant to support further deployments of troops overseas. President Trump knows this and he has consistently stated that he seeks to pull US troops out of the Middle East.

In fact, the opposite has happened. And once again, the decision to kill General Soleimani is pulling the US further into the Middle East and putting into stark light the inconsistency of Trump’s foreign policy ambitions. In recent days, the United States has committed to sending thousands of troops to the region.

Continued US troop deployments may not play well with Trump’s base, though they currently support his Iran policy. But absent an obvious justification, this could change, so it is not surprising that this has become a rallying point for Vice President Pence.

An even greater political risk, and one that will matter to the president, is the risk to US military personnel and civilians overseas. Public support for the killing of Soleimani and increased US presence in the region is bound to dissipate if Americans are killed.

But it isn’t clear how the president will respond, and already the death of one American in the militia attack on 27 December seems to have been a critical factor in Trump’s decision to authorize the assassination of General Soleimani.  

So far, Iran’s response appears to be calibrated to avoid this kind of public backlash, and keep the door open to some sort of managed resolution of the current crisis.

But the considerable risk of miscalculation and mistakes has already been born out. A week after the killing of Soleimani, the world is tuning in to the tragic news that a civilian airliner departing Iran for Ukraine appears to have been accidentally shot down by an Iranian missile, resulting in the deaths of all 176 people on board, including 82 Iranians and 63 Canadians.

Whether the US president is constrained is a critical question for Americans, for US democracy and for the rest of the world. Trump is different, but he is not unconstrained. Steps taken by Congress along with diplomatic and political pressure mean he is still operating within boundaries. But it is clear that these boundaries are being redefined.

The Climate vs. Donald Trump

19 November 2016

Rob Bailey

Former Research Director, Energy, Environment and Resources
All countries stand to lose if the US backslides on climate change, most of all the US.

On 7 November, as governments reconvened in Marrakech for the first major round of climate talks since the momentous Paris summit, they had the wind in their sails. The sense of momentum that had built in the run-up to Paris had continued, with recent global deals to phase out HFCs (potent greenhouse gases used in refrigeration and air conditioning) and tackle emissions from aviation. However, by the morning of 9 November the mood changed to one of unease and trepidation, as news of Donald Trump’s US election victory sunk in. Only days after entering into force, the Paris Agreement was faced with the possibility of the world’s second largest emitter, and a key dealmaker and architect of the regime, withdrawing.

Although details of Trump’s positions on climate and energy policy are scarce, his statements on the campaign trail appear to signal a marked departure from the Obama administration’s approach. The president-elect has said he would ‘cancel’ the Paris Agreement and ‘rescind’ the Climate Action Plan which underpins US action to reduce emissions. On the basis of these statements, it is hard to view the election result as anything other than a major setback for the climate. The new international climate regime now faces a very early and very big test.

Paris’s first test

The response from governments has been swift. Statement after statement emphasized a clear and consistent message: countries remain committed to the Paris Agreement and to delivering their emissions reductions. While there is hope that the US will remain a part, the message was that the process will continue regardless. Importantly, there have as yet been no indications that recusant parties to the agreement might use a US withdrawal as cover to do the same.

This display of unity is arguably Marrakech’s defining success. Progress in talks to flesh out the so-called ‘rulebook’ for how the Paris Agreement will operate come 2020 was modest in some areas and disappointing in others; on finance, the perennial tensions between developed and developing countries were as clear as ever. But when the time came to uphold the nascent regime in the face of a threat, powerful international norms on climate action meant there were no divisions.

Two important questions

The prospect of US disengagement from the international regime, whether de jure or de facto, raises two important questions: one for the US and another for the rest of the world.

For the international community, the question is one of leadership. In the run-up to Paris, the US and China together set expectations for a global agreement, signalling their intent through a series of joint announcements that set the bar for ambition and carried other countries with them. Progressive countries hoped this partnership would re-emerge in 2018, when talks begin on closing the gap between national emission reduction plans and what is needed to achieve the Paris goal of containing warming ‘well below’ 2°C. A wholesale step change in ambition is required if the 2°C goal is to remain within reach, requiring intense climate diplomacy of the kind witnessed before Paris. Will China be prepared to unilaterally set the pace and raise ambition first? Will a new partner come forward, or new coalition emerge, to fill the vacuum left by the US and work alongside China to provide leadership?

The US faces a question of national interest. With the rest of the world apparently united on climate change, what costs might the US incur were it to withdraw from the global regime? To fly in the face of strong international norms on climate action would certainly erode American soft power and concede global status to China, which continues to signal its ambition to decarbonize. And with the US expected to take a more protectionist approach to trade, it is possible that other countries, frustrated at US free-riding on the emissions reductions of others, might impose tariffs on American imports to adjust for the lower emissions costs of US exporters. Nor will American prosperity be served by the US economy remaining shackled to fossil fuels while the rest of the world’s economy transitions away from them. All countries stand to lose if the US backslides on climate change, most of all the US.

Comprehensive Glycomic Analysis Reveals That Human Serum Albumin Glycation Specifically Affects the Pharmacokinetics and Efficacy of Different Anticoagulant Drugs in Diabetes

Long-term hyperglycemia in patients with diabetes leads to human serum albumin (HSA) glycation, which may impair HSA function as a transport protein and affect the therapeutic efficacy of anticoagulants in patients with diabetes. In this study, a novel mass spectrometry approach was developed to reveal the differences in the profiles of HSA glycation sites between patients with diabetes and healthy subjects. K199 was the glycation site most significantly changed in patients with diabetes, contributing to different interactions of glycated HSA and normal HSA with two types of anticoagulant drugs, heparin and warfarin. An in vitro experiment showed that the binding affinity to warfarin became stronger when HSA was glycated, while HSA binding to heparin was not significantly influenced by glycation. A pharmacokinetic study showed a decreased level of free warfarin in the plasma of diabetic rats. A preliminary retrospective clinical study also revealed that there was a statistically significant difference in the anticoagulant efficacy between patients with diabetes and patients without diabetes who had been treated with warfarin. Our work suggests that larger studies are needed to provide additional specific guidance for patients with diabetes when they are administered anticoagulant drugs or drugs for treating other chronic diseases.

Professor Tim Benton, Research Director, Emerging Risks; Director, Energy, Environment and Resources Programme, Chatham House
Professor Paul Stevens, Distinguished Fellow, Energy, Environment and Resources Programme, Chatham House
Antony Froggatt, Senior Research Fellow, Energy, Environment and Resources Programme, Chatham House
Chair: Glada Lahn, Senior Research Fellow, Energy, Environment and Resources Programme

The Forecasting Forum 2020 will present the latest thinking from the Chatham House Energy, Environment and Resources Department's senior research team on the dynamics that will affect fossil fuel and energy investments and markets in the year ahead.

14:00 - 14:30 | Introduction and Climate Risks Outlook 

In the last decade, following the financial crisis, the literature on systemic risks has grown. Systemic risks occur when complex, non-linear, interconnected systems fail, often through relatively small perturbations, as their impacts cascade and amplify across the system. Within this context, climate change is a 'threat multiplier' with the risks increasing in scale, frequency and magnitude. Just as complex systems can pass thresholds and tip from a functional state to a non-functional state, so can societies and people’s attitudes. Together risk cascades or systemic risks and attitudinal tipping points have the potential to rapidly change the way the world works. 

Professor Tim Benton will open the Forecasting Forum 2020 with reflections on what this might mean for the pace and linearity of the fossil fuel transition.

14:30 - 15:30 | Session 1: An Outlook on Oil Prices in 2020

In this session, Professor Paul Stevens will argue that the recent events associated with the assassination of Iranian General Qasem Soleimani have exacerbated the sensitivity of oil markets to political events and brought 'geopolitics' back into global oil prices. Up to 2014, geopolitics played a key role in determining oil prices in the paper markets where perceptions and expectations ruled. By 2014, the world was so oversupplied with real oil barrels that the oil price collapsed and little attention was given to geopolitical events as geopolitics became marginalized in the determination of crude oil prices. However, recent events in the Middle East suggest that prices will become increasingly volatile but, at the same time, benefit from a rising geopolitical premium.

15:45 - 16:45 | Session 2: An Outlook for Energy in 2020

Recent years have brought significant disruption to the European power sector. Not only are many of Europe’s major utilities restructuring their businesses in light of decarbonization and technological developments but Brexit has distracted - and detracted from - efforts to create more systemic energy linkages between the UK and the rest of Europe. During his presentation, Antony Froggatt will draw on his ongoing research to outline what he believes are the prevailing challenges and opportunities for the European power sector over the coming year while highlighting some of the most significant global trends.

Please note, attendance at this event is by invitation only.

The Trump Immigration Plan: A Lopsided Proposal

The White House immigration plan offered as a solution to resolve the fate of DREAMers seeks legal immigration cuts unlike any seen since 1924. In addition to a decrease of up to 40 percent in family-sponsored immigration, the proposal demands vast increases in enforcement and a retrenchment in protections for those seeking humanitarian relief. In exchange, one-sixth of the unauthorized population could gain legal status.

Trump Administration Ratchets up Pressure on “Sanctuary” Jurisdictions

The Trump administration has been steadily building a case to penalize "sanctuary" cities—those jurisdictions that in some way limit their cooperation with federal immigration authorities—after threatening to cut federal funding.

Shaping a Narrative of &quot;Crisis&quot; at Border, Trump Administration Takes Muscular Action

The Trump administration took sweeping action in 2018 to slow legal immigration, make life harder for some immigrants already in the United States, rebuff would-be asylum seekers, and reduce refugee resettlement. Shaping a narrative of crisis at the border, the administration significantly changed the U.S. asylum system, deployed troops and tear gas, and separated families—yet Central American migrants continued to arrive.
