Unequal taxation helped fuel the French Revolution, say economists‎

Deep inequalities in taxation played a key role in fueling the French Revolution, according to a new study published by the ROCKWOOL Foundation Berlin (RFBerlin). For the first time, economists have substantiated this with figures. In areas where salt taxes and internal customs duties were particularly high, there were twice as many revolts as in low-tax districts between 1750 and 1789.

Supportive supervisors lift performance for employees with disabilities, study finds‎

Supportive supervisors can improve the performance of employees with disabilities, according to research in the International Journal of Business Innovation and Research. However, the broader workplace environment determines how much that support translates into results.

Most of the moon's water likely remains chemically bound in its deep interior‎

After decades of analyzing reams of lunar rocks back here on Earth, the canonical view of the moon was that it was anhydrous; that it had extraordinarily little water. That all began to change in 2009 with new data from NASA's Lunar Crater Observation and Sensing Satellite (LCROSS) and the much-ballyhooed evidence of water ice in the moon's permanently shaded polar regions (PSRs).

How redefining one word strips the Endangered Species Act's ability to protect vital habitat‎

It wouldn't make much sense to prohibit people from shooting a threatened woodpecker while allowing its forest to be cut down, or to bar killing endangered salmon while allowing a dam to dry out their habitat.

Dead stars in our cosmic backyard: Astronomers spot four white dwarfs hiding under our noses‎

Researchers at the University of Warwick and the University of Colorado Boulder have directly observed, for the first time, four white dwarfs in binary star systems in our nearby region of space. These stellar binaries are all within 65 light-years of Earth, and one contains the ninth-closest white dwarf to the sun.

Hidden in Maya wall writings: A named astronomer emerges from 1,200-year-old calculations‎

Researchers have reconstructed and transcribed a mathematical formula from the site of Xultun, Guatemala, revealing the name of a Maya astronomer for the first time. During the Classic period (250–900 CE), mathematics and astronomy were a key part of Maya society, with complex calculations based on calendar dates and astronomical observations influencing everything from the erection of monuments to the inauguration of kings and queens.

Climate disclosure gives Canadian companies an edge with European investors, new research shows‎

Canadian companies that disclose their climate-related risks and impacts have a considerable advantage over those that don't when it comes to attracting financing from European institutional investors, according to our recent report for the Institute for Sustainable Finance at Queen's University.

Floating-electron catalyst withstands week in air while making ammonia under milder conditions‎

A surface electrene, BaSiN2:O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the long-standing air instability of electrene materials. Synthesized by doping barium silicon nitride with oxygen, the material forms a stable layer of freely floating electrons on its surface.
