Most jobs require teamwork. Are some people good team players? In this paper we design and test a new method for identifying individual contributions to group performance. We randomly assign people to multiple teams and predict team performance based on previously assessed individual skills. Some people consistently cause their group to exceed its predicted performance. We call these individuals “team players”. Team players score significantly higher on a well-established measure of social intelligence, but do not differ across a variety of other dimensions, including IQ, personality, education and gender. Social skills – defined as a single latent factor that combines social intelligence scores with the team player effect – improve group performance about as much as IQ. We find suggestive evidence that team players increase effort among teammates.

A recent IAEA report on Iran’s nuclear program was portrayed by most Western mainstream media and politicians as new proof Iran is close to building nuclear weapons. The US Senate passed sanctions on Iran targeting its central bank in response.

However, the report does not say what the mainstream media and politicians claim. It has been much more guarded and much of it is about the state of Iran’s program up to 2003. After that period, the report is much more uncertain. Furthermore, many experts contend that the speculations (not definitive proof) that are in the report are misguided, too, leaning on unreliable sources, for example.

This update to the page on Iran has more information about this. Although the page is long, look for the new section about half way down under the heading of Regurgitating old stories as new information to justify sanctions?

• Facebook is taking a harder line on misinformation related to coronavirus than it has on other health topics in the past.
• This decision may increase the pressure on the company to act more decisively against other forms of harmful falsehoods that spread on its social networks.
• Facebook is banning events that promote flouting lockdown protests, and is removing the conspiracy theory video "Plandemic."
• But false claims that vaccines are dangerous still proliferate on Facebook — even though they contribute to the deaths of children.

Amid the pandemic, Facebook is taking a harder line on misinformation than it has in the past. That decision may come back to haunt it.

As coronavirus has wreaked havoc across the globe, forcing lockdowns and disrupting economies, false information and hoaxes have spread like wildfire on social media. Miracle cures, intentional disinformation about government policies, and wild claims that Bill Gates orchestrated the entire health crisis abound.

In the past, Facebook has been heavily criticised for failing to take action to stop its platform being used to facilitate the spread of misinformation. To be sure, coronavirus falsehoods are still easily found on Facebook — but the company has taken more decisive action than in previous years:

• For starters, Facebook is now displaying warning messages to people who have shared false information about COVID-19. They're imperfect — Stat reported that they may be too vague in their wording to have a major impact — but it's a step further than Facebook has taken on misinformation in the past.
• The company is also taking down event pages for events that reject mainstream science on coronavirus by calling on people to flout lockdown rules.
• And it is banning "Plandemic," a conspiratorial video about coronavirus that has been going viral on social media and contains numerous falsehoods.

But Facebook's actions to combat COVID-19 misinformation may backfire — in the sense that it has the potential to dramatically increase pressure on the company to take stronger action against other forms of misinformation.

The company has long struggled with how to handle fake news and hoaxes; historically, its approach is not to delete them, but to try to artificially stifle their reach via algorithmic tweaks. Despite this, pseudoscience, anti-government conspiracy theories, and other falsehoods still abound on the social network.

Facebook has now demonstrated that it is willing to take more decisive action on misinformation, when the stakes are high enough. Its critics may subsequently ask why it is so reticent to combat the issue when it causes harm in other areas — particularly around other medical misinformation.

One expected defence for Facebook? That it is focused on taking down content that causes "imminent harm," and while COVID-19 misinformation falls into that category, lots of other sorts of falsehoods don't.

However, using "imminence" as the barometer of acceptability is dubious: Vaccine denialism directly results in the deaths of babies and children. That this harm isn't "imminent" doesn't make it any less dangerous — but, for now, such material is freely posted on Facebook.

Far-right conspiracy theories like Pizzagate, and more recent, Qanon, have also spread on Facebook — stoking baseless fears of shadowy cabals secretly controlling the government. These theories don't intrinsically incite harm, but have been linked to multiple acts of violence, from a Pizzagate believer firing his weapon in a pizza parlour to the Qanon-linked killing of a Gambino crime boss. (Earlier this week, Facebook did take down some popular QAnon pages — but for breaking its rules on fake profiles, rather than disinformation.)

And Facebook is still full of groups rallying against 5G technology, making evidence-free claims about its health effects (and now, sometimes linking it to coronavirus in a messy web). These posts exist on a continuum, with believers at the extreme end attempting to burn down radio towers and assault technicians; Facebook does take down such incitements to violence, but the more general fearmongering that can act as a gateway to more extreme action remains.

This week, Facebook announced the first 20 members of its Oversight Board — a "Supreme Court"-style entity that will review reports from users make rulings as to what objectionable content is and isn't allowed on Facebook and Instagram, with — in theory — the power to overrule the company. It remains to be seen whether its decisions may affect the company's approach for misinformation, and it still needs to appoint the rest of its members and get up and running.

For now, limits remain in place as to what Facebook will countenance in its fight against coronavirus-specific misinformation.

CEO Mark Zuckerberg said the company would immediately take down posts advertising dangerous false cures to COVID-19, like drinking bleach. It is "obviously going to create imminent harm," he said in March. "That is just in a completely different class of content than the back-and-forth accusations a candidate might make in an election."

But in April, President Donald Trump suggested that people might try injecting a "disinfectant" as a cure, which both has the potential to be extremely harmful, and will not cure coronavirus.

Facebook is not taking down video of his comments.

Telomeres are specific nucleoprotein structures that are located at the ends of linear eukaryotic chromosomes and play crucial roles in genomic stability. Telomere DNA consists of simple repeats of a short G-rich sequence: TTAGGG in mammals and TTTAGGG in most plants. In recent years, the mammalian telomeric G-rich repeats have been shown to form G-quadruplex (G4) structures, which are crucial for modulating telomere functions. Surprisingly, even though plant telomeres are essential for plant growth, development, and environmental adaptions, only few reports exist on plant telomeric G4 DNA (pTG4). Here, using bulk and single-molecule assays, including CD spectroscopy, and single-molecule FRET approaches, we comprehensively characterized the structure and dynamics of a typical plant telomeric sequence, d[GGG(TTTAGGG)3]. We found that this sequence can fold into mixed G4s in potassium, including parallel and antiparallel structures. We also directly detected intermediate dynamic transitions, including G-hairpin, parallel G-triplex, and antiparallel G-triplex structures. Moreover, we observed that pTG4 is unfolded by the AtRecQ2 helicase but not by AtRecQ3. The results of our work shed light on our understanding about the existence, topological structures, stability, intermediates, unwinding, and functions of pTG4.

Formate oxidation to carbon dioxide is a key reaction in one-carbon compound metabolism, and its reverse reaction represents the first step in carbon assimilation in the acetogenic and methanogenic branches of many anaerobic organisms. The molybdenum-containing dehydrogenase FdsABG is a soluble NAD+-dependent formate dehydrogenase and a member of the NADH dehydrogenase superfamily. Here, we present the first structure of the FdsBG subcomplex of the cytosolic FdsABG formate dehydrogenase from the hydrogen-oxidizing bacterium Cupriavidus necator H16 both with and without bound NADH. The structures revealed that the two iron-sulfur clusters, Fe4S4 in FdsB and Fe2S2 in FdsG, are closer to the FMN than they are in other NADH dehydrogenases. Rapid kinetic studies and EPR measurements of rapid freeze-quenched samples of the NADH reduction of FdsBG identified a neutral flavin semiquinone, FMNH•, not previously observed to participate in NADH-mediated reduction of the FdsABG holoenzyme. We found that this semiquinone forms through the transfer of one electron from the fully reduced FMNH−, initially formed via NADH-mediated reduction, to the Fe2S2 cluster. This Fe2S2 cluster is not part of the on-path chain of iron-sulfur clusters connecting the FMN of FdsB with the active-site molybdenum center of FdsA. According to the NADH-bound structure, the nicotinamide ring stacks onto the re-face of the FMN. However, NADH binding significantly reduced the electron density for the isoalloxazine ring of FMN and induced a conformational change in residues of the FMN-binding pocket that display peptide-bond flipping upon NAD+ binding in proper NADH dehydrogenases.
