Why 'Christian nationalists' are less likely to wear masks and social distance
A new study used survey data to examine the interplay between Christian nationalism and incautious behaviors during the COVID-19 pandemic. The researchers defined Christian nationalism as "an ideology that idealizes and advocates a fusion of American civic life with a particular type of Christian identity and culture." The results showed that Christian nationalism was the leading predictor that A

They also discovered that higher levels of liver enzymes — proteins released when the liver is damaged — were associated with poorer outcomes for these patients, including ICU admission, mechanical ventilation, and

Integration of gene regulatory networks in understanding animal behavior
For years, scientists have attributed animal behavior to the coordinated activities of neuronal cells and its circuits of neurons, known as the neuronal network (NN). However, researchers are pushing the boundaries in understanding animal behavior through the integration of gene regulation.

Unfiltered lessons of a female entrepreneur
Women today are founding more businesses than ever. In 2018, they made up 40% of new entrepreneurs, yet in that same year, they received just 2.2% of all venture capital investment. The playing field is off-balance. So what can women do? They can get candid with each other. In this Big Think Live session, Victoria Montgomery Brown , co-founder and CEO of Big Think, and Charles Duhigg, Pulitzer Pr

NASA Says It Will Stop Using Racist Names for Space Objects
Taking Stock NASA has an unfortunate history of granting insensitive and bigoted nicknames to stars, galaxies, and other stuff in space. Because of that, the space agency announced on Wednesday that it's taking stock of all the various nicknames it's assigned and eliminating any that don't pass muster. In those instances, NASA says that going forward it will only use the official, acronym- and nu

NASA sounding rocket finds helium structures in sun's atmosphere
Helium is the second most abundant element in the universe after hydrogen. But scientists aren't sure just how much there actually is in the Sun's atmosphere, where it is hard to measure. Knowing the amount of helium in the solar atmosphere is important to understanding the origin and acceleration of the solar wind—the constant stream of charged particles from the Sun.
