There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science story that fell through the cracks in 2020, each day from December 25 through January 5. Today: the structure of folklore can help explain how unrelated facts and false information connect into a compelling narrative framework that can then go viral as a conspiracy theory.

Younger generations are blamed for the pandemic's spread, but also face the brunt of the transmission risk that comes with keeping the economy going. 6 MINUTE READ BY REBECCA RENNER PUBLISHED SEPTEMBER 17, 2020 WHEN PARAMEDICS RUSHED the pregnant Honduran woman into the emergency room, 28-year-old Chuan-Jay Jeffrey Chen stood ready to receive her. It was April, and the pandemic had already taken over his final year as an emergency medicine resident. Of all the coronavirus patients surging into Massachusetts General Hospital in Boston, this 32-year-old patient remains Chen's most memorable. The woman was so short of breath she could barely speak, so Chen would need to intubate her-a tricky procedure that requires precision as well as speed. Every moment without oxygen causes a patient's chances of survival to decline; pregnancy further complicates the scenario by making airways swollen, causing blood pressure to drop more quickly. As Chen set to work and talked her through the steps in Spanish, he also tried to calm his own nerves. "I knew I had very little margin for error," says Chen. The woman's husband had been barred from entering the building because of coronavirus restrictionsgen-z

This virus wasn't something we knew nothing about. There was so much we knew, from day one, including because of SARS, the previous almost-pandemic that was also a similar coronavirus. We could have used that vital pre-information better if we had matched the requisite epistemic humility that a pandemic requires-an acknowledgement that we aren't certain of anything-with an insistence that this situation wasn't a blank slate. We could have utilized our prior knowledge to plan ahead, while not letting go of the uncertainty-taking thoughtful steps but without overstating our confidence.

Normally, causal influence is assumed to go only one way-from cause to effect-and never back from the effect to the cause-the ringing of a bell does not cause the pressing of the button that triggered it. Now, researchers from the University of Oxford and the Université libre de Bruxelles have developed a theory of causality in quantum theory, according to which cause-effect relations can sometimes form cycles. This theory offers a novel understanding of exotic processes in which events do not have a definite causal order. The study has been published in Nature Communications.

The massive blast of Siberia-like cold that is wreaking havoc across North America is proving that if we humans want to keep surviving frigid winters, we are going to have to keep burning natural gas - and lots of it - for decades to come.

Today's pandemic offers the sector an opportunity to break that trajectory. "Crises are moments of change," Alice Obrecht, the head of policy for ALNAP, says. "They make it impossible to act in the way you were acting before." To understand where we might go from here, a look back at how the aid sector has changed - grown up, really - over the past 25 years is helpful: from the Rwanda genocide in 1994 to the 2004 Indian Ocean tsunami; from September 11th 2001 to 2013's Typhoon Haiyan in the Philippines, and then the 2015 surge of refugees across the Mediterranean, humanitarianism has helped pick up the pieces and allowed people to restart their lives.

As social distancing became norm and law in the early days of the Covid-19 pandemic, people turned to video teleconferencing to meet with friends and family, attend religious services, and go on dates. Zoom work accounts became a conduit for maintaining nonwork social ties, and as people came to depend on this enterprise tool, Zoom's stock valuation soared.1 The pandemic has widened the sphere of life dependent on such market technologies, heightening existing questions around the political, legal, and economic governance of these companies. How should the fabric of social life, especially as it is rewoven by the pandemic, relate to the private ownership of telecommunications?

Aside from filtering, warming, and humidifying the air you breathe, the nose is your first line of defense against allergens and pathogens. The mucus and cilia inside are designed to block these outside invaders from going farther down the respiratory tract and making you sick. And NO, which is what the sinuses release when you breathe through your nose, is a vasodilator, meaning it relaxes the blood vessels and lowers blood pressure.

GPT-3, a new text-generating program from OpenAI, shows how far the field has come-and how far it has to go.

Most recent macro trends - cloud compute, social, mobile, crypto, AI - that have reshaped the technology landscape are rooted in new technical capabilities or pushing the frontier of product form factors. Another shock to the system is emerging today, driven not by the underlying technology, but by an evolution in customer buying behavior. For shorthand, we think of this trend as "growth+sales": the bottom-up growth motion eventually layered with top-down sales.

Research from the University of Notre Dame estimates that more than 100,000 people were already infected with COVID-19 by early March-when only 1,514 cases and 39 deaths had been officially reported and before a national emergency was declared. The study provides insight into how limited testing and gaps in surveillance during the initial phase of the epidemic resulted in so many cases going undetected. The study was published in the Proceedings of the National Academy of Sciences.

This week, Cruise, the autonomous driving startup acquired by General Motors, announced its Origin, a self-driving vehicle that purports to be what comes next after the car. The Origin looks a bit like a large metal box on wheels. It lacks pedals, a steering wheel, a trunk, or even an engine, and has doors that slide open to reveal an interior with two facing bench seats. It is intended to act as a shuttle service that drives itself. Call the Origin with an app, get to where you're going, and never own a car again. That's the idea, anyway.

Silicon is the second-most abundant element in Earth's crust and it plays a vital role in plant life, both on land and in the sea. Silicon is used by plants in tissue building, which helps to ward off herbivorous animals. In the ocean, phytoplankton consume enormous amounts of silicon; they get a constant supply courtesy of rivers and streams. And silicon winds up in rivers and streams due to erosion of silicon-containing rocks. Land plants also use silicon. They get it from the soil. In this new effort, the researchers began by noting that the terrestrial biogeochemical cycling of silicon (how it moves from plants back to the soil and then into plants again) is poorly understood. To gain a better understanding of how it works, they ventured to a part of Western Australia that, unlike other parts of the world, has not been impacted by Pleistocene glaciations. The soil there gave the researchers a look at the silicon cycle going back 2 million years.

ot long ago, Joe Davis, the "artist-scientist" in George Church's genetics lab at Harvard Medical School, was in Brittany, France. The region is known for thousand-year-old salterns that produce fleur de sel, or flower of salt-salt that forms as seawater evaporates. Davis was there sampling these brightly colored ponds with a microscope, and found in the shallow waters an abundance of diverse halophiles, organisms that can grow in and tolerate saline conditions. "I wondered what happens to these organisms," he said. "The salt is evaporating, the water's gone. The organisms aren't just going to disappear. Where are they?"
