Atoms and molecules are the building blocks of chemistry and are important to our understanding of the world. By cooling atoms and molecules to ultracold temperatures it opens up a new understanding of quantum chemistry. Working with nanokelvin temperatures, one billion times colder than Antarctica during winter, researchers can observe and control particles in ways not possible at room temperature. When really cold, particles behave in strange and exciting ways. Researchers are discovering unexpected results by looking at particles from a quantum perspective.
A study of more than 2,000 streams around North America found that those altered by human activity are at greater risk of flooding.
The study from the University of Waterloo analyzed the seasonal flow patterns of 2,272 streams in Canada and the U.S. and found that human-managed streams – those impacted by developments like dams, canals, or heavy urbanization – had significantly different flow patterns compared to streams in natural watersheds.
International Women’s Day is a time for celebrating the social, cultural and economic inroads women have made towards gender equality. This year’s theme, Break the Bias, has resonated with many women who have navigated long-standing barriers, glass ceilings and oppressive stigmas that continue to exist both at the workplace and in the greater community.
