The UK's new Online Safety Bill 10 February 2021 — 3:00PM TO 3:45PM Anonymous (not verified) 26 January 2021 Online

Discussing the new proposals which include the establishment of a new ‘duty of care’ on companies to ensure they have robust systems in place to keep their users safe.

Governments, regulators and tech companies are currently grappling with the challenge of how to promote an open and vibrant internet at the same time as tackling harmful activity online, including the spread of hateful content, terrorist propaganda, and the conduct of cyberbullying, child sexual exploitation and abuse.

The UK government’s Online Harms proposals include the establishment of a new ‘duty of care’ on companies to ensure they have robust systems in place to keep their users safe. Compliance with this new duty will be overseen by an independent regulator.

On 15 December 2020, DCMS and the Home Office published the full UK government response, setting out the intended policy positions for the regulatory framework, and confirming Ofcom as the regulator.

With the legislation likely to be introduced early this year, the panel will discuss questions including:

• How to strike the balance between freedom of expression and protecting adults from harmful material?

• How to ensure the legislation’s approach to harm is sufficiently future-proofed so new trends and harms are covered as they emerge?

• What additional responsibilities will tech companies have under the new regulation?

• Will the regulator have sufficient powers to tackle the wide range of harms in question?

This event is invite-only for participants, but you can watch the livestream of the discussion on this page at 15.00 GMT on Wednesday 10 February.

Facebook's power under scrutiny as Trump ban upheld Expert comment NCapeling 6 May 2021

Keeping Donald Trump’s Facebook ban in place shows the vast power social media platforms hold, raising questions of whether that power is appropriately used.

Kate Jones

From a human rights perspective, the Oversight Board’s decision is a strong one, and not at all surprising. The board decided Facebook was right to suspend the former president’s access to post content on Facebook and Instagram, but not indefinitely.

It found Donald Trump’s posts violated Facebook’s community standards because they amounted to praise or support of people engaged in violence and that, applying a human rights assessment, Facebook’s suspension of Trump was a necessary and proportionate restriction of his right to freedom of expression.

However the board also found Trump’s indefinite suspension was neither in conformity with a clear Facebook procedure nor consistent with its commitment to respect human rights. Its decision requires Facebook to make a new decision on the future of Donald Trump’s account, grounded in its rules.

While opinions on this result will differ, the increased call for clear and accessible rules and respect for human rights in their implementation that the Oversight Board brings to Facebook’s operations is welcome.

But the Oversight Board’s powers are limited to content moderation – Facebook declined to answer the board’s questions about amplification of Trump’s posts through the platform’s design decisions and algorithms. This limitation on the board’s role should be lifted. It is in content amplification, not just content moderation, that Facebook should face scrutiny and accountability for the sake of the human rights of its users.

Fundamentally, human rights is not a veneer which can mask or legitimize underlying power dynamics or public policy – those still fall to be assessed for themselves.

The Trump/Facebook saga does highlight the vast power Facebook and other major social media platforms have over political discussion and persuasion. Through granting or denying, or through amplifying or quietening the voices of political figures, Facebook has the power to shape politics, electorates, and democratic processes. Improving content moderation through the Oversight Board, although important, does little to constrain that power.

Facebook itself, unlike a government, has no accountability to the general public, and the Oversight Board must not distract us from the need for a full conversation about the extent to which Facebook’s power is appropriately held and properly wielded.

Emily Taylor

This decision marks a coming of age for Facebook’s content moderation process. For years, decisions to take down content or ban users have been opaque, conducted by a human workforce that Facebook and other platforms have been hesitant to acknowledge. The platforms have also been worried that being seen to exercise an editorial function might put at risk the legal protections which prevent the platforms being held responsible for user-generated content.

When the Oversight Board was first posited, observers questioned whether a body funded by Facebook could properly exercise a legitimate appeals function. Now there is a reasoned decision which partly supports the decision to de-platform a serving president, but also takes issue with the indefinite nature of the ban.

Facebook specifically asked the Oversight Board to consider specific challenges involved when the person involved is a political leader. The board concluded that Trump’s ‘status as head of state with a high position of trust not only imbued his words with greater force and credibility but also created risks that his followers would understand they could act with impunity’. The storming of the US Capitol and role President Trump played in stirring up the violence underlined that political leaders’ words can motivate others to take harmful actions.

Just as the events of January 6 remain shocking, it remains shocking that private platforms have exercised the power to curb the speech of a US president. It also remains shocking that the platforms sat back and took no action over the previous four years, but waited until the final days of the transition.

The board’s decision is an evolution in private-sector content moderation, with a diverse board giving a reasoned opinion on a Facebook decision. But to fully comply with the principles of open justice, board decisions should include more detail on the individuals who have made the decision – at present, it appears all members of the board review the decision but it is not clear which individuals were involved in its drafting, or that they were clear from conflicts. If the process is to gain respect as a truly independent oversight on the platform’s decisions, greater transparency over the identity of decision-makers will be needed.

Mark Zuckerberg expressed concern about Facebook becoming an arbiter of truth or free speech and, overall, the difficulty of having private companies managing the application of fundamental rights on their platforms has not been solved. Just because companies have the financial resources to do it, does not mean they necessarily should.

Yet no other international governance or arbitration system has emerged to handle the complexities of platform power over speech. In the context of that vacuum, the Oversight Board’s decision is a welcome step.

Undercurrents: The Oversight Board's Trump decision, and Merkel's legacy Audio bhorton.drupal 25 June 2021

Was Facebook right to suspend Trump? And how will Merkel be remembered?

In the wake of the storming of Capitol Hill on 6 January 2021, social media platforms took steps to remove former President Donald Trump from their websites for infringing community standards. This step was welcomed by many, but also raised serious questions about the power of social media companies to limit free speech and censor elected officials. The suspension of President Trump from Facebook was referred to the Oversight Board, an independent body of experts set up to scrutinise the platform’s content moderation decisions.  

In this episode, Ben speaks to Thomas Hughes and Kate Jones about the outcome of the Oversight Board’s inquiry into the Trump suspension, and the wider implications for content moderation on social media.  

Then Lara is joined by Hans Kundnani to assess the political outlook in Germany and reflect on the legacy of outgoing Chancellor Angela Merkel.  

The molecular mechanisms of reduced frataxin (FXN) expression in Friedreich's ataxia (FRDA) are linked to epigenetic modification of the FXN locus caused by the disease-associated GAA expansion. Here, we identify that SUV4-20 histone methyltransferases, specifically SUV4-20 H1, play an important role in the regulation of FXN expression and represent a novel therapeutic target. Using a human FXN–GAA–Luciferase repeat expansion genomic DNA reporter model of FRDA, we screened the Structural Genomics Consortium epigenetic probe collection. We found that pharmacological inhibition of the SUV4-20 methyltransferases by the tool compound A-196 increased the expression of FXN by ∼1.5-fold in the reporter cell line. In several FRDA cell lines and patient-derived primary peripheral blood mononuclear cells, A-196 increased FXN expression by up to 2-fold, an effect not seen in WT cells. SUV4-20 inhibition was accompanied by a reduction in H4K20me2 and H4K20me3 and an increase in H4K20me1, but only modest (1.4–7.8%) perturbation in genome-wide expression was observed. Finally, based on the structural activity relationship and crystal structure of A-196, novel small molecule A-196 analogs were synthesized and shown to give a 20-fold increase in potency for increasing FXN expression. Overall, our results suggest that histone methylation is important in the regulation of FXN expression and highlight SUV4-20 H1 as a potential novel therapeutic target for FRDA.

Histone recognition by “reader” modules serves as a fundamental mechanism in epigenetic regulation. Previous studies have shown that Spindlin1 is a reader of histone H3K4me3 as well as “K4me3-R8me2a” and promotes transcription of rDNA or Wnt/TCF4 target genes. Here we show that Spindlin1 also acts as a potent reader of histone H3 “K4me3-K9me3/2” bivalent methylation pattern. Calorimetric titration revealed a binding affinity of 16 nm between Spindlin1 and H3 “K4me3-K9me3” peptide, which is one to three orders of magnitude stronger than most other histone readout events at peptide level. Structural studies revealed concurrent recognition of H3K4me3 and H3K9me3/2 by aromatic pockets 2 and 1 of Spindlin1, respectively. Epigenomic profiling studies showed that Spindlin1 colocalizes with both H3K4me3 and H3K9me3 peaks in a subset of genes enriched in biological processes of transcription and its regulation. Moreover, the distribution of Spindlin1 peaks is primarily associated with H3K4me3 but not H3K9me3, which suggests that Spindlin1 is a downstream effector of H3K4me3 generated in heterochromatic regions. Collectively, our work calls attention to an intriguing function of Spindlin1 as a potent H3 “K4me3-K9me3/2” bivalent mark reader, thereby balancing gene expression and silencing in H3K9me3/2-enriched regions.

Phospholipase Cε (PLCε) is activated downstream of G protein–coupled receptors and receptor tyrosine kinases through direct interactions with small GTPases, including Rap1A and Ras. Although Ras has been reported to allosterically activate the lipase, it is not known whether Rap1A has the same ability or what its molecular mechanism might be. Rap1A activates PLCε in response to the stimulation of β-adrenergic receptors, translocating the complex to the perinuclear membrane. Because the C-terminal Ras association (RA2) domain of PLCε was proposed to the primary binding site for Rap1A, we first confirmed using purified proteins that the RA2 domain is indeed essential for activation by Rap1A. However, we also showed that the PLCε pleckstrin homology (PH) domain and first two EF hands (EF1/2) are required for Rap1A activation and identified hydrophobic residues on the surface of the RA2 domain that are also necessary. Small-angle X-ray scattering showed that Rap1A binding induces and stabilizes discrete conformational states in PLCε variants that can be activated by the GTPase. These data, together with the recent structure of a catalytically active fragment of PLCε, provide the first evidence that Rap1A, and by extension Ras, allosterically activate the lipase by promoting and stabilizing interactions between the RA2 domain and the PLCε core.

Korea's New Energy Policy and Implications for LNG Imports 3 October 2018 — 9:00AM TO 10:30AM Anonymous (not verified) 17 September 2018 Chatham House | 10 St James's Square | London | SW1Y 4LE

The new energy policy of Moon Jae-In’s administration aims to swing radically from coal and nuclear towards renewables and LNG for power generation. During the last 12 months the priority given to the expansion of renewable energy has been overwhelming and the support for the expansion of gas not as strong as many observers had expected. The 13th gas supply and demand plan announced in Spring 2018 confirmed the trend. Based on this projection, Professor K. Paik will discuss how this new energy policy will affect Korea’s LNG imports strategy and what are the implications of Korea’s northern policy towards this LNG supply strategy and pipeline gas imports to the Korean Peninsula.
