The capitalist economic system has always had a big problem with politics in societies with universal suffrage. Anticipating that, most capitalists opposed and long resisted extending suffrage beyond the rich who possessed capital. Only mass pressures from below forced repeated extensions of voting rights until universal suffrage was achieved-at least legally. To this day, capitalists develop and apply all sorts of legal and illegal mechanisms to limit and constrain suffrage. Among those committed to conserving capitalism, fear of universal suffrage runs deep. Trump and his Republicans exemplify and act on that fear as the 2020 election looms.

Numerous different microorganisms play an important role in the health and fitness, including humans, through their interactions with their host organism. The ability to enter into functional communication with the host also characterizes the archaea. They are basically known for their many special properties. Representatives of this group of microorganisms can also exist as so-called extremophiles under extraordinary living conditions, such as very high temperatures, high salt concentrations or in acidic environments.

An international research team from Germany and France has created structures in which light fields interact with electrons so strongly that the quantum vacuum itself is significantly altered. Using extremely short bursts of light, they interrupted this coupling much faster than the timescale of a vacuum fluctuation and observed an intriguing ringing of the emitted electromagnetic field, indicating the collapse of the vacuum state. Their key achievement could improve our understanding of the nature of nothingness-the vacuum of space itself, paving a way toward photonics exploiting vacuum fluctuations. The results are published in the current issue of Nature Photonics.

This sort of late-breaking Democratic vote is the new, though still underappreciated, normal in national elections. Americans have become accustomed to knowing who won our elections promptly, but there are many legitimate votes that are not counted immediately every election year. For reasons that are not totally understood by election observers, these votes tend to be heavily Democratic, leading results to tilt toward Democrats as more of them are counted, in what has become known as the "blue shift." In most cases, the blue shift is relatively inconsequential, changing final vote counts but not results. But in others, as in 2018, it can materially change the outcome.

Case isolation and contact tracing can contribute to the control of COVID-19 outbreaks1,2. However, it remains unclear how real-world social networks could influence the effectiveness and efficiency of such approaches. To address this issue, we simulated control strategies for SARS-CoV-2 transmission in a real-world social network generated from high-resolution GPS data that were gathered in the course of a citizen-science experiment3,4. We found that tracing the contacts of contacts reduced the size of simulated outbreaks more than tracing of only contacts, but this strategy also resulted in almost half of the local population being quarantined at a single point in time. Testing and releasing non-infectious individuals from quarantine led to increases in outbreak size, suggesting that contact tracing and quarantine might be most effective as a 'local lockdown' strategy when contact rates are high. Finally, we estimated that combining physical distancing with contact tracing could enable epidemic control while reducing the number of quarantined individuals. Our findings suggest that targeted tracing and quarantine strategies would be most efficient when combined with other control measures such as physical distancing.

Some national chains, both retail and restaurants, are closing outlets in New York City, which are struggling more than their branches elsewhere.

Mandates for mask use in public during the recent COVID-19 pandemic, worsened by global shortage of commercial supplies, have led to widespread use of homemade masks and mask alternatives. It is assumed that wearing such masks reduces the likelihood for an infected person to spread the disease, but many of these mask designs have not been tested in practice. We have demonstrated a simple optical measurement method to evaluate the efficacy of masks to reduce the transmission of respiratory droplets during regular speech. In proof-of-principle studies, we compared a variety of commonly available mask types and observed that some mask types approach the performance of standard surgical masks, while some mask alternatives, such as neck fleece or bandanas, offer very little protection. Our measurement setup is inexpensive and can be built and operated by non-experts, allowing for rapid evaluation of mask performance during speech, sneezing, or coughing.

A pheromone molecule that makes crop-damaging locusts swarm has been identified. Could this pheromone, which is sensed by odorant receptors, be used to trap these insects and prevent the agricultural devastation that they cause?

Contrary to common beliefs on fiscal fundamentals, the current debt crisis in the global periphery demonstrates that the solvency of sovereign states is determined by their monetary power. Crucially, liquidity has a cyclical character in the periphery of global capitalism and a countercyclical character in the core.
