Smith in "Toward Progressive Narratives of American Identity," published in Polity's May Symposium on the Challenges Facing Democrats.
According to recent Gallup polls, socialism is now more popular than capitalism among Democrats and young people, and support for "some form of socialism" among all Americans is at 43% (compared to 25% in 1942). Policies that went unmentioned or were declared out-of-bounds in elections four years ago—a federal jobs guarantee, single-payer health care, free college, massive tax hikes on the rich,...

Texas researchers from the University of Houston, Baylor University and Texas A&M University have discovered evidence for why the earth cooled dramatically 13,000 years ago, dropping temperatures by about 3 degrees Centigrade.
The fields of condensed matter physics and materials science are intimately linked because new physics is often discovered in materials with special arrangements of atoms. Crystals, which have repeating units of atoms in space, can have special patterns which result in exotic physical properties. Particularly exciting are materials which host multiple types of exotic properties because they give...
Scientists have developed a new model that successfully predicted seven of the Sun's biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.
When we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example. High-res imaging shows the cerebellum is 80% of the area of the cortex, indicating it has grown as human behavior and cognition evolved.

When NASA's Aqua satellite passed over the North Atlantic Ocean, it gathered water vapor data on Isaias, while NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image that showed a more organized tropical cyclone.
Jupiter, named for the king of the ancient Roman gods, commands its own mini-version of our solar system of circling satellites; their movements convinced Galileo Galilei that Earth is not the center of the universe in the early 17th century. More than 400 years later, astronomers will use NASA's James Webb Space Telescope to observe these famous subjects, pushing the observatory's instruments to...

Residents of Ontario can now download a new app that can tell them whether they have been around someone who has tested positive for COVID-19 over the previous two weeks. But while government officials say the goal is to make the contact notification app available across the country, they can't say yet when it will be available in other...

Scientists at Tokyo Institute of Technology explore a novel and simplistic method to synthesize manganese dioxide with a specific crystalline structure called β-MnO2. Their study sheds light on how different synthesis conditions can produce manganese dioxide with distinct porous structures, hinting at a strategy for the development of highly tuned MnO2 nanomaterials that could serve as catalysts...
Sea surface temperatures in the tropics have a major influence on the climate in the tropics and the adjacent continents. For example, they determine the position of the Intertropical Convergence Zone and the beginning and strength of the West African monsoon. Therefore, it is important to understand the variability of sea surface temperatures for climate predictions. Until now, the seasonal cycle...
Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties.
