ari Congress To Hold Another UFO/UAP Hearing By entertainment.slashdot.org Published On :: 2024-11-13T07:00:00+00:00 Longtime Slashdot reader thephydes writes: The hearing will go ahead on November 13 at 11:30 ET (16:30 GMT). Apparently, it will "further pull back the curtain on secret UAP research programs conducted by the U.S. government, and undisclosed findings they have yielded," according to a House statement. It's driven by two republicans, Nancy Mace (R-S.C.) and Glenn Grothman (R-Wis.), who say: "Americans deserve to understand what the government has learned about UAP sightings, and the nature of any potential threats these phenomena pose. We can only ensure that understanding by providing consistent, systemic transparency. We look forward to hearing from expert witnesses on ways to shed more light and bring greater accountability to this issue." "Expert witnesses in the hearing will include Luis Elizondo, a decorated former counterintelligence officer who has claimed for years that the U.S. government is hiding knowledge of UAP, including materials recovered from crashed flying saucers," reports Space.com. "The House hearing will also include Tim Gallaudet, a retired U.S. Navy Rear Admiral who unidentified submersible objects, arguing that 'these underwater anomalies jeopardize US maritime security.'" "Other speakers at the hearing include journalist Michael Shellenberger, who has also claimed the U.S. government is hiding UFO crash retrieval programs, and former NASA Associate Administrator of Space Policy and Partnerships Michael Gold, who is a member of NASA's independent UAP study team."

ari China is attempting a precarious balancing act By www.chathamhouse.org Published On :: Thu, 09 Mar 2023 15:43:31 +0000 China is attempting a precarious balancing act Expert comment NCapeling 9 March 2023 In its efforts to maintain ties with both Russia and Europe, China is having to wade through conflicting interests and rapidly changing sentiments. Precisely how far China will go in supporting Russia has been one of the most important questions of the war in Ukraine. On 20 February, US secretary of state Antony Blinken warned China may soon provide arms (‘lethal support’) to Moscow. But then, on 24 February – the anniversary of Russia’s invasion – China released a position paper calling for a political settlement to end the conflict, tellingly omitting any mention of its ‘no-limits partnership’ with Russia. China’s goal was to present itself as a neutral mediator. In fact, Beijing’s ties with Russia remain unchanged, even if this relationship has grown more exasperating for Chinese diplomats over the past year. Their job is to continue striking a delicate balance, a task that is becoming increasingly difficult as Russian president Vladimir Putin doubles down on nuclear brinkmanship and reckless rhetoric. Staying out of the Ukraine war With Putin extolling the law of the jungle in its most brutal form, China must be careful not to involve itself too much in the conflict. After all, Russia is clearly losing, and China has high hopes of repairing ties with major European economies. With China focused on moves by the US and its allies in East Asia and the Indo-Pacific, it simply cannot afford sabre-rattling or unrest on its other borders But Putin is of course keen to signal that China has his back. That is why he recently rolled out the red carpet for China’s top diplomat Wang Yi and then alluded to an (unconfirmed) upcoming visit by Chinese president Xi Jinping. Such diplomatic developments allow him to present China’s ambivalent position as, in fact, an endorsement of the invasion. While the costs of aligning with Russia could easily outweigh the benefits for China, one must remember that China’s reasons for maintaining good relations with the Kremlin go beyond the war in Ukraine. For starters, the two countries share a 2,672-mile (4,300-kilometer) border – roughly equivalent to the width of Europe – and the frontier’s exact location was not even finally settled until the beginning of this century, after generations of negotiations that included some 2,000 meetings. Yet to this day, the spectre of the Sino-Soviet split in the 1950s and 1960s looms large on both sides and it is not likely to be exorcised anytime soon. With China focused on moves by the US and its allies in East Asia and the Indo-Pacific, it simply cannot afford sabre-rattling or unrest on its other borders. Moreover, unlike the collective West, China’s foreign policy has always been shaped by interests rather than by values. Even with respect to Russia, the two countries’ bond is based mainly on shared resentment of US hegemony. By deepening their bilateral cooperation in recent years, they have been able to achieve a level of great-power status with which to counterbalance America. Being isolated from the ‘collective West’ is not an attractive option for China, given its hopes of achieving a robust economic rebound after years of the zero-COVID policy But Putin’s misadventure in Ukraine has forced Xi and China’s newly minted Politburo to manage a new set of economic, financial, and political risks. Russia’s war has left the West more firmly united than it has been in years. As China’s relations with the US have reached new lows, Chinese leaders want to avoid also alienating the European Union (EU), which is one of the country’s biggest trading partners. This is why Xi and Chinese diplomats have been so careful not to accept the Kremlin’s talking points in full. Being isolated from the ‘collective West’ is not an attractive option for China, given its hopes of achieving a robust economic rebound after years of the zero-COVID policy. Balancing Europe with the Global South In seeking to keep diplomatic and trade channels open, China’s main tactic has been to reassure European countries that it will use its own ties with Russia to restrain Putin from deploying nuclear weapons. At the same time, China is making a renewed push to strengthen its ties with the Global South where many countries do not see the war in Ukraine in the same stark moral terms as the West does. The emphasis on energy and food security in China’s recent position paper may have struck a chord with developing countries that have been reeling from the war’s negative knock-on effects on their economies.

The outcome of the US presidential election will have significant, intersecting implications for global as well as American business. At stake will be the degree of continuity and stability on both the domestic and international fronts, with a Harris presidency pursuing policies building broadly on the Biden Administration and a second Trump Administration departing sharply from them—with both shaped and limited by control of Congress.An already volatile geopolitical environment and global economy may become even more unpredictable in the face of potential American political instability and uncertain leadership in the international community.Please join us for this critical session to discuss:How might trade policy differ between a Harris and Trump presidency? Will national security pressures, especially over China, lead to greater policy commonalities than expected?What might differing approaches to decarbonization and the energy transition mean for the future of policy toward EVs, critical mineral supply chains, and ‘green’ industrial subsidy?How might each Administration approach fiscal policy? Will either push for a tightening to the current loose policy—and what may be implications for US debt and the dollar?What economic effects can we expect in the case of a disputed election result or non-peaceful transfer of power—and will Corporate America be compelled to make public statements?

ari Shaping modern Britain: the role of African and Caribbean communities By www.chathamhouse.org Published On :: Thu, 03 Oct 2024 07:27:13 +0000 Shaping modern Britain: the role of African and Caribbean communities 24 October 2024 — 5:00PM TO 6:00PM Anonymous (not verified) 3 October 2024 Chatham House and Online As part of Black History Month, this event celebrates the enduring contributions of African and Caribbean communities to the UK. When British colonial rule ended, newly independent countries in Africa and the Caribbean retained influences such as the English language and governance systems modelled on that of the UK. Initially, these post-independence relations were largely marked by the UK’s soft power, shaping the nation-building processes in these regions.Over time, however, this influence has become a two-way exchange. African and Caribbean cultures have profoundly shaped modern Britain – from music and food to sports, arts, literature and beyond. These evolving dynamics have not only enriched the UK’s cultural landscape but also provided significant benefits for diaspora communities, fostering a sense of belonging and promoting cultural exchange. Diaspora groups and civil society organizations have adeptly utilised these connections to advocate for their communities and advance their interests.At this event, speakers will explore how African and Caribbean influences rose to prominence in the UK and how this cultural momentum can be harnessed to build stronger, forward-looking partnerships. By highlighting the shared histories and more vibrant present-day exchanges, this event will explore how these ties can be used to break down stereotypes, promote social cohesion, and contribute to a more inclusive future.This event forms part of our series of events celebrating Black History Month, including a photo exhibition and drinks reception.

In 2022, the Biden administration called upon the world’s democracies to unite against a rising tide of autocracy. Through its messaging, conferences, and op-eds, the US and its allies presented the public with a binary choice: democracy or autocracy. But in today’s world, and in the practice of international relations, the choice is rarely this simple. Joel Rosenthal, president of Carnegie Council, joins Chatham House to discuss how democracies and multilateral institutions can leverage ethics as a tool to assess concerns and trade-offs when engaging with illiberal actors. Can democracies afford to be adversarial with certain countries or overly selective in cooperation when facing global-scale challenges such as climate change and the emergence of AI? How can democracies simultaneously defend human rights and promote open societies while still engaging with leaders from non-democratic states as strategic allies? Full Article

ari Enhanced enzyme kinetics of reverse transcriptase variants cloned from animals infected with SIVmac239 lacking viral protein X [Microbiology] By www.jbc.org Published On :: 2020-12-11T00:06:20-08:00 HIV Type 1 (HIV-1) and simian immunodeficiency virus (SIV) display differential replication kinetics in macrophages. This is because high expression levels of the active host deoxynucleotide triphosphohydrolase sterile α motif domain and histidine-aspartate domain–containing protein 1 (SAMHD1) deplete intracellular dNTPs, which restrict HIV-1 reverse transcription, and result in a restrictive infection in this myeloid cell type. Some SIVs overcome SAMHD1 restriction using viral protein X (Vpx), a viral accessory protein that induces proteasomal degradation of SAMHD1, increasing cellular dNTP concentrations and enabling efficient proviral DNA synthesis. We previously reported that SAMHD1-noncounteracting lentiviruses may have evolved to harbor RT proteins that efficiently polymerize DNA, even at low dNTP concentrations, to circumvent SAMHD1 restriction. Here we investigated whether RTs from SIVmac239 virus lacking a Vpx protein evolve during in vivo infection to more efficiently synthesize DNA at the low dNTP concentrations found in macrophages. Sequence analysis of RTs cloned from Vpx (+) and Vpx (−) SIVmac239–infected animals revealed that Vpx (−) RTs contained more extensive mutations than Vpx (+) RTs. Although the amino acid substitutions were dispersed indiscriminately across the protein, steady-state and pre-steady-state analysis demonstrated that selected SIVmac239 Vpx (−) RTs are characterized by higher catalytic efficiency and incorporation efficiency values than RTs cloned from SIVmac239 Vpx (+) infections. Overall, this study supports the possibility that the loss of Vpx may generate in vivo SIVmac239 RT variants that can counteract the limited availability of dNTP substrate in macrophages.

ari A drug-resistant {beta}-lactamase variant changes the conformation of its active-site proton shuttle to alter substrate specificity and inhibitor potency [Microbiology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Lys234 is one of the residues present in class A β-lactamases that is under selective pressure due to antibiotic use. Located adjacent to proton shuttle residue Ser130, it is suggested to play a role in proton transfer during catalysis of the antibiotics. The mechanism underpinning how substitutions in this position modulate inhibitor efficiency and substrate specificity leading to drug resistance is unclear. The K234R substitution identified in several inhibitor-resistant β-lactamase variants is associated with decreased potency of the inhibitor clavulanic acid, which is used in combination with amoxicillin to overcome β-lactamase–mediated antibiotic resistance. Here we show that for CTX-M-14 β-lactamase, whereas Lys234 is required for hydrolysis of cephalosporins such as cefotaxime, either lysine or arginine is sufficient for hydrolysis of ampicillin. Further, by determining the acylation and deacylation rates for cefotaxime hydrolysis, we show that both rates are fast, and neither is rate-limiting. The K234R substitution causes a 1500-fold decrease in the cefotaxime acylation rate but a 5-fold increase in kcat for ampicillin, suggesting that the K234R enzyme is a good penicillinase but a poor cephalosporinase due to slow acylation. Structural results suggest that the slow acylation by the K234R enzyme is due to a conformational change in Ser130, and this change also leads to decreased inhibition potency of clavulanic acid. Because other inhibitor resistance mutations also act through changes at Ser130 and such changes drastically reduce cephalosporin but not penicillin hydrolysis, we suggest that clavulanic acid paired with an oxyimino-cephalosporin rather than penicillin would impede the evolution of resistance.
