Americans' reliance on facts to discuss public issues has declined significantly in the past two decades, leading to political paralysis and collapse of civil discourse, according to a RAND Corporation report.

This phenomenon, referred to as "Truth Decay," is defined by increasing disagreement about facts, a blurring between opinion and fact, an increase in the relative volume of opinion and personal experience over fact, and declining trust in formerly respected sources of factual information.

Applied mathematics can be a powerful tool in helping predict the genesis and evolution of different types of cancers, a study from the University of Waterloo has found.

The study used a form of mathematical analysis called evolutionary dynamics to look at how malignant mutations evolve in both stem and non-stem cells in colorectal and intestinal cancers.

Taking the Oath of Allegiance at a naturalization ceremony is an emotional moment for many immigrants, and for good reason: it is the culmination of an often arduous process and many years of striving. Citizenship also opens a new chapter marked by possibility, from better job prospects to full participation in civic life.

Researchers at Carnegie Mellon University have developed a new dynamic statistical model to visualize changing patterns in networks, including gene expression during developmental periods of the brain.

Over half of Canadian youth and young adults who have consumed energy drinks have experienced negative health effects as a result, according to a study from the University of Waterloo.

In a nationwide survey of Canadian youth, over half of those who had ever consumed an energy drink had reported experiencing an adverse health event, including rapid heartbeat, nausea, and in rare cases, seizures.

LOGAN, UTAH, USA - Methane is a potent greenhouse gas, trapping more solar radiation on Earth than carbon dioxide. It's also the primary component of natural gas, a critical fuel source for heating and other uses. For these reasons and more, scientists are keenly interested in how the gas is made.

PHILADELPHIA -- (Jan. 15, 2018) -- New research led by The Wistar Institute, in collaboration with Sun Yat-sen University in China, has characterized the transitory presence of myeloid-derived suppressor cells (MDSCs) in mouse and human newborns, revealing a critical role of these cells in regulation of inflammation in the early stages of life. This study was published online in Nature Medicine.

Feelings about the frequency of rape or other forms of sexual assault in a neighborhood are significantly tied to women's--but not men's--perceptions of its safety, according to new research.

However, both men and women report feeling less safe in their neighborhoods based on the presence of other violence, including weapon-based fights, robberies, muggings and gang fights.

Phytoplankton blooms are one of the most important factors contributing to the efficiency of the carbon pump in the North Atlantic Ocean. To better understand this phenomenon, the ERC remOcean[1] project, led by researchers at the Laboratoire d'Océanographie de Villefranche (CNRS/UPMC), has developed a new class of robots: biogeochemical profiling floats, the first robots able to collect data in the ocean throughout the year. Using these unparalleled data, the researchers have identified the starting point for the explosive spring phytoplankton bloom.

President Donald Trump signed Executive Order 13769 on Jan. 27, 2017, effectively barring individuals from seven predominately Muslim countries from entering the United States for 90 days.

Within a day of his decree, thousands of protesters flooded airports around the country in opposition to what was quickly deemed a "Muslim ban," and by March 6, the order had been formally revoked.
