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.

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.

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.

When telling a story, common but invisible words-a, the, it-are used in certain ways and at certain moments. In a study published in Science Advances, researchers from The University of Texas at Austin and Lancaster University in Lancaster, United Kingdom, recorded the use of such words across thousands of fictional and nonfictional stories, mapping a universal blueprint for storytelling.

this is how living in the COVID era can feel. We know that an unprecedented economic cataclysm has rippled across the globe. But the precise consequences of this catastrophe - for the global economy, geopolitics, climate change, and our own little lives - remain opaque.

group of researchers from three Japanese universities has discovered why the western subarctic Pacific Ocean, which accounts for only 6 percent of the world's oceans, produces an estimated 26 percent of the world's marine resources.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection platforms currently report qualitative results. However, technology based on RT-PCR allows for calculation of viral load, which is associated with transmission risk and disease severity in other viral illnesses.1 Viral load in COVID-19 might correlate with infectivity, disease phenotype, morbidity, and mortality. To date, no studies have assessed the association between viral load and mortality in a large patient cohort.2, 3, 4 To our knowledge, we are the first to report on SARS-CoV-2 viral load at diagnosis as an independent predictor of mortality in a large hospitalised cohort (n=1145).

BY NOW THERE'S little doubt about hydroxychloroquine: It doesn't work for treating Covid-19. But there's a bigger, more important lesson hidden in the story of its failure-a rarely-mentioned, but altogether crucial, error baked into the early research. The scientists who ran the first, promising laboratory experiments on the drug had used the wrong kind of cells: Instead of testing its effects on human lung cells, they relied on a supply of mass-produced, standardized cells made from a monkey's kidney. In the end, that poor decision made their findings more or less irrelevant to human health. Worse, it's possible that further research into novel Covid-19 cures will end up being compromised by the same mistake.

People the world over have acquired a passing familiarity with epidemic models, critical threshold values for transmission (R0), comorbidities, and exponential growth. But these insights into the pandemic are like Harrison's H1-3; they focus on a few elements of the problem. The pandemic is every bit as much a problem of the non-linear dynamics of markets, the cognitive biases of decision-makers, the collective dynamics of groups, and the coevolution of biological species - humans, mammalian food sources, and viral agents.
