Softbank-backed delivery startup Rappi is testing out robots for contactless delivery — take a look

  • Colombian delivery app Rappi is testing pilot robot deliveries in Colombia.
  • Rappi operates in several Latin American countries, and last year SoftBank invested one billion dollars into the startup.
  • Deliveries are made using Kiwibot, a delivery robot from a Colombian owned company in California.
  • Visit Business Insider's homepage for more stories.

Colombian delivery app Rappi is yet another company turning to robots to reduce reliance on human workers during the coronavirus pandemic. 

In addition to Colombia, Rappi operates in Mexico, Peru, Chile, Uruguay, Argentina, and Brazil. Last spring, SoftBank invested $1 billion — one-fifth of its Innovation Fund for Latin America — in the startup. It was founded in 2015, and other investors include Sequoia Capital, Andreesen Horowitz, and Y Combinator.

Colombia is currently under a lockdown set to end in May, though it may be extended again. Earlier this month, Bloomberg reported on the lack of coronavirus testing throughout Latin America, making it difficult to assess how widespread the virus is in the region.

Like in other countries, the Colombian delivery app is using robots to complete orders at a time when people are at risk of catching the virus from interacting with others. So far, the robots are part of a pilot in Medellin, with potential to expand.

Here's what it looks like.

Rappi is using robots for deliveries in Medellin, the capital of Colombia.



Typically, Rappi works similarly to GrubHub or DoorDash, with delivery drivers picking up orders and bringing them to customers' doors.



As the coronavirus spread between people, options for contactless delivery became more popular.



Deliveries in the pilot program use Kiwibot robots, from a California company with a Medellin office.



The four-wheeled delivery robots have orange flags to call attention from walkers, drivers, and bikers.



Customers stuck at home because of the coronavirus can order and pay for meals digitally, and then last mile delivery is completed by the robots.



Robots can carry deliveries up to five square inches in size, and are disinfected between orders.

Kiwibots have a stereo camera system to sense its surroundings as it moves.



The sensor system allows it to react to lights and obstacles.



Kiwibots are equipped with corner recognition, which allows them to create safe paths on sidewalks.



Kiwibot emphasized its robots ability to "seamlessly mesh into the fabric of urban landscapes," with technology like street crossing mode.

Source: Kiwibot



Rappi says it completes about 120 deliveries each day with the 15 robots in the pilot area.

It plans to run the program until July, and then potentially expand to other cities.



Kiwibots have previously been used for deliveries at colleges including UC Berkeley, and Kiwibot says it has made more than 30,000 deliveries since it started in 2017.

Global health system needs reform to help deliver SDGs, says new report

24 September 2015

20150922RethinkingGlobalHealthArchitecture.jpg

The global health system has contributed significantly to improved health and life expectancy in recent decades. However, the existing architecture needs to be reformed in order to address future challenges and meet the health targets in the Sustainable Development Goals. Rethinking the Global Health System, a new Chatham House report, analyses how fit for purpose the current system is and identifies priority areas for reform. 

The Ebola crisis has shown that weak systems make individual countries more vulnerable and that strong, resilient and equitable systems at country level are needed to protect global health security. There is a pressing need for enhanced global disease surveillance and detection capacity, as well as improved international coordination in responding to emerging health threats.

In addition, addressing determinants of health outside the health sector requires cross-sectoral collaboration and linkages to other policy domains. Historically, the focus has rested on directly reducing illness and death, but the need to address other influences on health outcomes – safe drinking water, proper sewage treatment, good education – is now well recognized.

The report says that stronger leadership in global health is therefore required and the report lends support to calls for the creation of a new organization that would bring together United Nations agencies with health-related mandates – UN-HEALTH. Just as UNAIDS created a more coherent response for HIV, a UN-HEALTH organization could achieve a similar but more wide-reaching effect by bringing together and streamlining all UN agencies working on global health issues.

Professor David Harper, who led the Chatham House project that resulted in the report, said: 

'This report is intended to make a substantial contribution to the international debate on what the world will require of the health architecture of the future. It offers some options for political leaders to consider, but it is just a starting point. More work is urgently needed to develop the ideas introduced in this project and to help generate the high-level political traction that is so vital in any change process.'

Radical new business model for pharmaceutical industry needed to avert antibiotic resistance crisis

7 October 2015

20151009Antibiotics.jpg

Revenues for pharmaceutical companies need to be 'delinked' from sales of antibiotics to avoid their over-use and avert a public health crisis, says a new report from the think-tank Chatham House.

Over-use of antibiotics is contributing to the growing resistance of potentially deadly bacteria to existing drugs, threatening a public health crisis in the near future. The report notes that, by 2050, failing to tackle antibiotic resistance could result in 10 million premature deaths per year.                                       

Novel antibiotics to combat resistant pathogens are thus desperately needed, but market incentives are exacerbating the problem. Towards a New Global Business Model for Antibiotics: Delinking Revenues from Sales states that,                                       


'The current business model requires high levels of antibiotic use in order to recover the costs of R&D. But mitigating the spread of resistance demands just the opposite: restrictions on the use of antibiotics.'

                                       

To tackle this catch-22 problem, the Centre on Global Health Security at Chatham House recommends the establishment of a global body to implement a radical new business model for the industry, which would encourage investment and promote global access to - and conservation of - antibiotics.      

The current business model has several perverse effects. As R&D is an inherently risky and costly endeavour, the industry is chronically under-investing in new treatments. Today, few large pharmaceutical companies retain active antibacterial drug discovery programmes. Re-stoking the industry's interest in antibiotics would be one of the primary roles of the new body.   

Secondly, the need to recover sunk cost under the current business model encourages both high prices and over-marketing of successful drugs, making potentially life-saving treatments unaffordable to many in developing countries, while simultaneously encouraging over-use in developed markets and increasing resistance.   

The new global body would address these challenges by ‘delinking’ pharmaceutical revenues from sales of antibiotics. It would do this by directly financing the research and development of new drugs, which it would then acquire at a price based on production costs rather than the recovery of R&D expenses. Acquisition could take the form of procurement contracts with companies, the purchase of full IP rights or other licensing mechanisms.                                       

This would enable it to promote global access to antibiotics while simultaneously restricting over-use. Conservation would be promoted through education, regulation and good clinical practice, with the report recommending that 'proven conservation methods such as antibiotic stewardship programmes… be incentivized and implemented immediately.'

Priorities for R&D financing would be based on a comprehensive assessment of  threats arising from resistance. Antibiotics would qualify for the highest level of financial incentives if they combat resistant pathogens posing a serious threat to human health.                                       

Finance for the new body would come from individual nation states, with the report noting that this could 'begin with a core group of countries with significant research activity and large antibiotic markets, (though) it is envisaged that all high income countries should make an appropriate financial contribution.'                                 

It is not yet clear exactly how much funding would be necessary to combat resistance, but with inaction expected to cost $100 trillion in cumulative economic damage, the report argues that 'an additional global investment of up to $3.5 billion a year (about 10 per cent of the current value of global sales of antibiotics) would be a bargain.'

Reduction of protein phosphatase 2A (PP2A) complexity reveals cellular functions and dephosphorylation motifs of the PP2A/B'{delta} holoenzyme [Enzymology]

Protein phosphatase 2A (PP2A) is a large enzyme family responsible for most cellular Ser/Thr dephosphorylation events. PP2A substrate specificity, localization, and regulation by second messengers rely on more than a dozen regulatory subunits (including B/R2, B'/R5, and B″/R3), which form the PP2A heterotrimeric holoenzyme by associating with a dimer comprising scaffolding (A) and catalytic (C) subunits. Because of partial redundancy and high endogenous expression of PP2A holoenzymes, traditional approaches of overexpressing, knocking down, or knocking out PP2A regulatory subunits have yielded only limited insights into their biological roles and substrates. To this end, here we sought to reduce the complexity of cellular PP2A holoenzymes. We used tetracycline-inducible expression of pairs of scaffolding and regulatory subunits with complementary charge-reversal substitutions in their interaction interfaces. For each of the three regulatory subunit families, we engineered A/B charge–swap variants that could bind to one another, but not to endogenous A and B subunits. Because endogenous Aα was targeted by a co-induced shRNA, endogenous B subunits were rapidly degraded, resulting in expression of predominantly a single PP2A heterotrimer composed of the A/B charge–swap pair and the endogenous catalytic subunit. Using B'δ/PPP2R5D, we show that PP2A complexity reduction, but not PP2A overexpression, reveals a role of this holoenzyme in suppression of extracellular signal–regulated kinase signaling and protein kinase A substrate dephosphorylation. When combined with global phosphoproteomics, the PP2A/B'δ reduction approach identified consensus dephosphorylation motifs in its substrates and suggested that residues surrounding the phosphorylation site play roles in PP2A substrate specificity.

Polarization of protease-activated receptor 2 (PAR-2) signaling is altered during airway epithelial remodeling and deciliation [Immunology]

Protease-activated receptor 2 (PAR-2) is activated by secreted proteases from immune cells or fungi. PAR-2 is normally expressed basolaterally in differentiated nasal ciliated cells. We hypothesized that epithelial remodeling during diseases characterized by cilial loss and squamous metaplasia may alter PAR-2 polarization. Here, using a fluorescent arrestin assay, we confirmed that the common fungal airway pathogen Aspergillus fumigatus activates heterologously-expressed PAR-2. Endogenous PAR-2 activation in submerged airway RPMI 2650 or NCI–H520 squamous cells increased intracellular calcium levels and granulocyte macrophage–colony-stimulating factor, tumor necrosis factor α, and interleukin (IL)-6 secretion. RPMI 2650 cells cultured at an air–liquid interface (ALI) responded to apically or basolaterally applied PAR-2 agonists. However, well-differentiated primary nasal epithelial ALIs responded only to basolateral PAR-2 stimulation, indicated by calcium elevation, increased cilia beat frequency, and increased fluid and cytokine secretion. We exposed primary cells to disease-related modifiers that alter epithelial morphology, including IL-13, cigarette smoke condensate, and retinoic acid deficiency, at concentrations and times that altered epithelial morphology without causing breakdown of the epithelial barrier to model early disease states. These altered primary cultures responded to both apical and basolateral PAR-2 stimulation. Imaging nasal polyps and control middle turbinate explants, we found that nasal polyps, but not turbinates, exhibit apical calcium responses to PAR-2 stimulation. However, isolated ciliated cells from both polyps and turbinates maintained basolateral PAR-2 polarization, suggesting that the calcium responses originated from nonciliated cells. Altered PAR-2 polarization in disease-remodeled epithelia may enhance apical responses and increase sensitivity to inhaled proteases.

Virtual Breakfast: Is a Brexit Delay Possible?

Research Event

7 April 2020 - 8:30am to 9:30am

Event participants

Gavin Barwell, Downing Street Chief of Staff to Prime Minister Theresa May (2017-19)
Chair: Thomas Raines, Director, Europe Programme, Chatham House

Please note this an online-only event.

According to a previously agreed timetable for phase two of Brexit talks, negotiations on the future EU-UK trade relations were scheduled to begin in March. Then a global pandemic hit. Despite the ongoing COVID-19 outbreak, the UK government insists that the Brexit negotiations are on track and there are currently no plans to extend the transition period beyond 2020.

However, the original timetable for trade talks was already widely seen as extremely constrained. Can negotiations still be done in time? With the decision on any possible extension to be made by July at the latest, can the two sides make sufficient progress by that point? Or would the ongoing public health crisis make requesting an extension to the transition period more politically viable for the UK government? Finally, if there is no extension, could Britain still leave the EU with no deal?

In this webinar, the speaker will discuss how the need to manage other challenges, such as the current COVID-19 outbreak, might affect the government’s approach to the negotiations with the EU. He will also share his insights on what to expect from the second phase of negotiations and on the most important lessons from phase one.

Predictions and Policymaking: Complex Modelling Beyond COVID-19

The COVID-19 pandemic has highlighted the potential of complex systems modelling for policymaking but it is crucial to also understand its limitations.

Complex systems models have played a significant role in informing and shaping the public health measures adopted by governments in the context of the COVID-19 pandemic. For instance, modelling carried out by a team at Imperial College London is widely reported to have driven the approach in the UK from a strategy of mitigation to one of suppression.

Complex systems modelling will increasingly feed into policymaking by predicting a range of potential correlations, results and outcomes based on a set of parameters, assumptions, data and pre-defined interactions. It is already instrumental in developing risk mitigation and resilience measures to address and prepare for existential crises such as pandemics, prospects of a nuclear war, as well as climate change.

The human factor

In the end, model-driven approaches must stand up to the test of real-life data. Modelling for policymaking must take into account a number of caveats and limitations. Models are developed to help answer specific questions, and their predictions will depend on the hypotheses and definitions set by the modellers, which are subject to their individual and collective biases and assumptions. For instance, the models developed by Imperial College came with the caveated assumption that a policy of social distancing for people over 70 will have a 75 per cent compliance rate. This assumption is based on the modellers’ own perceptions of demographics and society, and may not reflect all societal factors that could impact this compliance rate in real life, such as gender, age, ethnicity, genetic diversity, economic stability, as well as access to food, supplies and healthcare. This is why modelling benefits from a cognitively diverse team who bring a wide range of knowledge and understanding to the early creation of a model.

The potential of artificial intelligence

Machine learning, or artificial intelligence (AI), has the potential to advance the capacity and accuracy of modelling techniques by identifying new patterns and interactions, and overcoming some of the limitations resulting from human assumptions and bias. Yet, increasing reliance on these techniques raises the issue of explainability. Policymakers need to be fully aware and understand the model, assumptions and input data behind any predictions and must be able to communicate this aspect of modelling in order to uphold democratic accountability and transparency in public decision-making.

In addition, models using machine learning techniques require extensive amounts of data, which must also be of high quality and as free from bias as possible to ensure accuracy and address the issues at stake. Although technology may be used in the process (i.e. automated extraction and processing of information with big data), data is ultimately created, collected, aggregated and analysed by and for human users. Datasets will reflect the individual and collective biases and assumptions of those creating, collecting, processing and analysing this data. Algorithmic bias is inevitable, and it is essential that policy- and decision-makers are fully aware of how reliable the systems are, as well as their potential social implications.

The age of distrust

Increasing use of emerging technologies for data- and evidence-based policymaking is taking place, paradoxically, in an era of growing mistrust towards expertise and experts, as infamously surmised by Michael Gove. Policymakers and subject-matter experts have faced increased public scrutiny of their findings and the resultant policies that they have been used to justify.

This distrust and scepticism within public discourse has only been fuelled by an ever-increasing availability of diffuse sources of information, not all of which are verifiable and robust. This has caused tension between experts, policymakers and public, which has led to conflicts and uncertainty over what data and predictions can be trusted, and to what degree. This dynamic is exacerbated when considering that certain individuals may purposefully misappropriate, or simply misinterpret, data to support their argument or policies. Politicians are presently considered the least trusted professionals by the UK public, highlighting the importance of better and more effective communication between the scientific community, policymakers and the populations affected by policy decisions.

Acknowledging limitations

While measures can and should be built in to improve the transparency and robustness of scientific models in order to counteract these common criticisms, it is important to acknowledge that there are limitations to the steps that can be taken. This is particularly the case when dealing with predictions of future events, which inherently involve degrees of uncertainty that cannot be fully accounted for by human or machine. As a result, if not carefully considered and communicated, the increased use of complex modelling in policymaking holds the potential to undermine and obfuscate the policymaking process, which may contribute towards significant mistakes being made, increased uncertainty, lack of trust in the models and in the political process and further disaffection of citizens.

The potential contribution of complexity modelling to the work of policymakers is undeniable. However, it is imperative to appreciate the inner workings and limitations of these models, such as the biases that underpin their functioning and the uncertainties that they will not be fully capable of accounting for, in spite of their immense power. They must be tested against the data, again and again, as new information becomes available or there is a risk of scientific models becoming embroiled in partisan politicization and potentially weaponized for political purposes. It is therefore important not to consider these models as oracles, but instead as one of many contributions to the process of policymaking.

Nuclear Tensions Must Not Be Sidelined During Coronavirus

1 May 2020

Research Assistant, International Security Programme
Although the pandemic means the Nuclear Non-Proliferation Treaty (NPT) Review Conference (RevCon) is postponed, the delay could be an opportunity to better the health of the NPT regime.

Despite face-to-face diplomatic meetings being increasingly rare during the current disruption, COVID-19 will ultimately force a redefinition of national security and defence spending priorities, and this could provide the possibility of an improved political climate at RevCon when it happens in 2021.

With US presidential elections due in November and a gradual engagement growing between the EU and Iran, there could be a new context for more cooperation between states by 2021. Two key areas of focus over the coming months will be the arms control talks between the United States and Russia, and Iran’s compliance with the 2015 Joint Comprehensive Plan of Action (JCPOA), also known as the Iran Nuclear Deal.

It is too early to discern the medium- and longer-term consequences of COVID-19 for defence ministries, but a greater focus on societal resilience and reinvigorating economic productivity will likely undercut the rationale for expensive nuclear modernization.

Therefore, extending the current New START (Strategic Arms Reduction Treaty) would be the best, most practical option to give both Russia and the United States time to explore more ambitious multilateral arms control measures, while allowing their current focus to remain on the pandemic and economic relief.

Continuing distrust

But with the current treaty — which limits nuclear warheads, missiles, bombers, and launchers — due to expire in February 2021, the continuing distrust between the United States and Russia makes this extension hard to achieve, and a follow-on treaty even less likely.

Prospects for future bilateral negotiations are hindered by President Donald Trump’s vision for a trilateral arms control initiative involving both China and Russia. But China opposes this on the grounds that its nuclear arsenal is far smaller than that of the two others.

While there appears to be agreement that the nuclear arsenals of China, France, and the UK (the NPT nuclear-weapons states) and those of the states outside the treaty (India, Pakistan, North Korea, and Israel) will all have to be taken into account going forward, a practical mechanism for doing so proves elusive.

If Joe Biden wins the US presidency he seems likely to pursue an extension of the New START treaty and could also prevent a withdrawal from the Open Skies treaty, the latest arms control agreement targeted by the Trump administration.

Under a Biden administration, the United States would also probably re-join the JCPOA, provided Tehran returned to strict compliance with the deal. Biden could even use the team that negotiated the Iran deal to advance the goal of denuclearization of the Korean peninsula.

For an NPT regime already confronted by a series of longstanding divergences, it is essential that Iran remains a signatory especially as tensions between Iran and the United States have escalated recently — due to the Qassim Suleimani assassination and the recent claim by Iran’s Revolutionary Guard Corps to have successfully placed the country’s first military satellite into orbit.

This announcement raised red flags among experts about whether Iran is developing intercontinental ballistic missiles due to the dual-use nature of space technology. The satellite launch — deeply troubling for Iran’s neighbours and the EU countries — may strengthen the US argument that it is a cover for the development of ballistic missiles capable of delivering nuclear weapons.

However, as with many other countries, Iran is struggling with a severe coronavirus crisis and will be pouring its scientific expertise and funds into that rather than other efforts — including the nuclear programme.

Those European countries supporting the trading mechanism INSTEX (Instrument in Support of Trade Exchanges) for sending humanitarian goods into Iran could use this crisis to encourage Iran to remain in compliance with the JCPOA and its NPT obligations.

France, Germany and the UK (the E3) have already successfully concluded the first transaction, which was to facilitate the export of medical goods from Europe to Iran. But the recent Iranian escalatory steps will most certainly place a strain on the preservation of this arrangement.

COVID-19 might have delayed Iran’s next breach of the 2015 nuclear agreement but Tehran will inevitably seek to strengthen its hand before any potential negotiations with the United States after the presidential elections.

As frosty US-Iranian relations — exacerbated by the coronavirus pandemic — prevent diplomatic negotiations, this constructive engagement between the E3 and Iran might prove instrumental in reviving the JCPOA and ensuring Iran stays committed to both nuclear non-proliferation and disarmament.

While countries focus their efforts on tackling the coronavirus pandemic, it is understandable resources may be limited for other global challenges, such as the increasing risk of nuclear weapons use across several regions.

But the potential ramifications of the COVID-19 crisis for the NPT regime are profound. Ongoing tensions between the nuclear-armed states must not be ignored while the world’s focus is elsewhere, and the nuclear community should continue to work together to progress nuclear non-proliferation and disarmament, building bridges of cooperation and trust that can long outlast the pandemic.

Despite face-to-face diplomatic meetings being increasingly rare during the current disruption, COVID-19 will ultimately force a redefinition of national security and defence spending priorities, and this could provide the possibility of an improved political climate at RevCon when it happens in 2021.

With US presidential elections due in November and a gradual engagement growing between the EU and Iran, there could be a new context for more cooperation between states by 2021. Two key areas of focus over the coming months will be the arms control talks between the United States and Russia, and Iran’s compliance with the 2015 Joint Comprehensive Plan of Action (JCPOA), also known as the Iran Nuclear Deal.

It is too early to discern the medium- and longer-term consequences of COVID-19 for defence ministries, but a greater focus on societal resilience and reinvigorating economic productivity will likely undercut the rationale for expensive nuclear modernization.

Therefore, extending the current New START (Strategic Arms Reduction Treaty) would be the best, most practical option to give both Russia and the United States time to explore more ambitious multilateral arms control measures, while allowing their current focus to remain on the pandemic and economic relief.

Continuing distrust

But with the current treaty — which limits nuclear warheads, missiles, bombers, and launchers — due to expire in February 2021, the continuing distrust between the United States and Russia makes this extension hard to achieve, and a follow-on treaty even less likely.

Prospects for future bilateral negotiations are hindered by President Donald Trump’s vision for a trilateral arms control initiative involving both China and Russia. But China opposes this on the grounds that its nuclear arsenal is far smaller than that of the two others.

While there appears to be agreement that the nuclear arsenals of China, France, and the UK (the NPT nuclear-weapons states) and those of the states outside the treaty (India, Pakistan, North Korea, and Israel) will all have to be taken into account going forward, a practical mechanism for doing so proves elusive.

If Joe Biden wins the US presidency he seems likely to pursue an extension of the New START treaty and could also prevent a withdrawal from the Open Skies treaty, the latest arms control agreement targeted by the Trump administration.

Under a Biden administration, the United States would also probably re-join the JCPOA, provided Tehran returned to strict compliance with the deal. Biden could even use the team that negotiated the Iran deal to advance the goal of denuclearization of the Korean peninsula.

For an NPT regime already confronted by a series of longstanding divergences, it is essential that Iran remains a signatory especially as tensions between Iran and the United States have escalated recently — due to the Qassim Suleimani assassination and the recent claim by Iran’s Revolutionary Guard Corps to have successfully placed the country’s first military satellite into orbit.

This announcement raised red flags among experts about whether Iran is developing intercontinental ballistic missiles due to the dual-use nature of space technology. The satellite launch — deeply troubling for Iran’s neighbours and the EU countries — may strengthen the US argument that it is a cover for the development of ballistic missiles capable of delivering nuclear weapons.

However, as with many other countries, Iran is struggling with a severe coronavirus crisis and will be pouring its scientific expertise and funds into that rather than other efforts — including the nuclear programme.

Those European countries supporting the trading mechanism INSTEX (Instrument in Support of Trade Exchanges) for sending humanitarian goods into Iran could use this crisis to encourage Iran to remain in compliance with the JCPOA and its NPT obligations.

France, Germany and the UK (the E3) have already successfully concluded the first transaction, which was to facilitate the export of medical goods from Europe to Iran. But the recent Iranian escalatory steps will most certainly place a strain on the preservation of this arrangement.

COVID-19 might have delayed Iran’s next breach of the 2015 nuclear agreement but Tehran will inevitably seek to strengthen its hand before any potential negotiations with the United States after the presidential elections.

As frosty US-Iranian relations — exacerbated by the coronavirus pandemic — prevent diplomatic negotiations, this constructive engagement between the E3 and Iran might prove instrumental in reviving the JCPOA and ensuring Iran stays committed to both nuclear non-proliferation and disarmament.

While countries focus their efforts on tackling the coronavirus pandemic, it is understandable resources may be limited for other global challenges, such as the increasing risk of nuclear weapons use across several regions.

But the potential ramifications of the COVID-19 crisis for the NPT regime are profound. Ongoing tensions between the nuclear-armed states must not be ignored while the world’s focus is elsewhere, and the nuclear community should continue to work together to progress nuclear non-proliferation and disarmament, building bridges of cooperation and trust that can long outlast the pandemic.

Roles of the DOCK-D family proteins in a mouse model of neuroinflammation [Neurobiology]

The DOCK-D (dedicator of cytokinesis D) family proteins are atypical guanine nucleotide exchange factors that regulate Rho GTPase activity. The family consists of Zizimin1 (DOCK9), Zizimin2 (DOCK11), and Zizimin3 (DOCK10). Functions of the DOCK-D family proteins are presently not well-explored, and the role of the DOCK-D family in neuroinflammation is unknown. In this study, we generated three mouse lines in which DOCK9 (DOCK9−/−), DOCK10 (DOCK10−/−), or DOCK11 (DOCK11−/−) had been deleted and examined the phenotypic effects of these gene deletions in MOG35–55 peptide-induced experimental autoimmune encephalomyelitis, an animal model of the neuroinflammatory disorder multiple sclerosis. We found that all the gene knockout lines were healthy and viable. The only phenotype observed under normal conditions was a slightly smaller proportion of B cells in splenocytes in DOCK10−/− mice than in the other mouse lines. We also found that the migration ability of macrophages is impaired in DOCK10−/− and DOCK11−/− mice and that the severity of experimental autoimmune encephalomyelitis was ameliorated only in DOCK10−/− mice. No apparent phenotype was observed for DOCK9−/− mice. Further investigations indicated that lipopolysaccharide stimulation up-regulates DOCK10 expression in microglia and that microglial migration is decreased in DOCK10−/− mice. Up-regulation of C–C motif chemokine ligand 2 (CCL2) expression induced by activation of Toll-like receptor 4 or 9 signaling was reduced in DOCK10−/− astrocytes compared with WT astrocytes. Taken together, our findings suggest that DOCK10 plays a role in innate immunity and neuroinflammation and might represent a potential therapeutic target for managing multiple sclerosis.

Although the pandemic means the Nuclear Non-Proliferation Treaty (NPT) Review Conference (RevCon) is postponed, the delay could be an opportunity to better the health of the NPT regime.

Delineating an extracellular redox-sensitive module in T-type Ca2+ channels [Membrane Biology]

T-type (Cav3) Ca2+ channels are important regulators of excitability and rhythmic activity of excitable cells. Among other voltage-gated Ca2+ channels, Cav3 channels are uniquely sensitive to oxidation and zinc. Using recombinant protein expression in HEK293 cells, patch clamp electrophysiology, site-directed mutagenesis, and homology modeling, we report here that modulation of Cav3.2 by redox agents and zinc is mediated by a unique extracellular module containing a high-affinity metal-binding site formed by the extracellular IS1–IS2 and IS3–IS4 loops of domain I and a cluster of extracellular cysteines in the IS1–IS2 loop. Patch clamp recording of recombinant Cav3.2 currents revealed that two cysteine-modifying agents, sodium (2-sulfonatoethyl) methanethiosulfonate (MTSES) and N-ethylmaleimide, as well as a reactive oxygen species–producing neuropeptide, substance P (SP), inhibit Cav3.2 current to similar degrees and that this inhibition is reversed by a reducing agent and a zinc chelator. Pre-application of MTSES prevented further SP-mediated current inhibition. Substitution of the zinc-binding residue His191 in Cav3.2 reduced the channel's sensitivity to MTSES, and introduction of the corresponding histidine into Cav3.1 sensitized it to MTSES. Removal of extracellular cysteines from the IS1–IS2 loop of Cav3.2 reduced its sensitivity to MTSES and SP. We hypothesize that oxidative modification of IS1–IS2 loop cysteines induces allosteric changes in the zinc-binding site of Cav3.2 so that it becomes sensitive to ambient zinc.

Some of the latest climate models provide unrealistically high projections of future warming

A new study from University of Michigan climate researchers concludes that some of the latest-generation climate models may be overly sensitive to carbon dioxide increases and therefore project future warming that is unrealistically high.

How modelling articulates the science of climate change

To imagine earth without greenhouse gases in its atmosphere is to turn the familiar blue marble into a barren lump of rock and ice on which the average surface temperature hovers around -18ºC. Such a planet would not receive less of the sunlight which is the ultimate source of all Earth's warmth. But when the energy it absorbed from the sunlight was re-emitted as infrared radiation, as the laws of physics require, it would head unimpeded back out into space.
