Corporate scandals have been on the rise for the past decade. In 2019, Strategy& (the strategy consulting business unit of PricewaterhouseCoopers) found that for the first time in the history of its annual survey, more CEOs were dismissed for ethical concerns than for poor firm performance or internal board struggles. There has been no shortage of highly publicized scandals, including the BP oil spill in 2010, the Target data breach in 2013 and abuses of financial incentives at Wells Fargo in 2016. A number of CEOs have resigned following alleged inappropriate relations, including Brian Krzanich at Intel, Leslie Moonves at CBS, ...

University of Houston atmospheric science researchers have found that while local emissions play a role in the rise of ozone levels in Houston, most of the pollutants can be carried in from other regions across the country, leading to excess ozone pollution. Their findings offer insights into strategies to mitigate future ozone pollution for the region. The research team focused on two ozone episodes in September 2021 (Sept. 6 – 11 and Sept. 23 – 26). The month of September is the typical annual ozone peak due to high temperatures, lack of rain and air circulation patterns that transport polluted air from the north. Their analysis revealed that roughly 63% of the excess ...

CHAMPAIGN, Ill. — Air pollution poses well-established risks to physical health, but an emerging body of research says that it may also have adverse effects on mental health. New research co-written by a University of Illinois Urbana-Champaign economist examining the relationship between air pollution via drifting wildfire smoke exposure and suicide risk found large-scale evidence that air pollution disproportionately elevates the risk of suicide among rural populations in the U.S. Each 10% increase in airborne particulate matter in rural counties causes monthly suicide rates ...

Many of today’s artificial intelligence systems loosely mimic the human brain. In a new paper, researchers suggest that another branch of biology — ecology — could inspire a whole new generation of AI to be more powerful, resilient, and socially responsible.  Published September 11 in Proceedings of the National Academy of Sciences, the paper argues for a synergy between AI and ecology that could both strengthen AI and help to solve complex global challenges, such as disease outbreaks, loss of biodiversity, and climate change ...

ARLINGTON HEIGHTS, Ill. (September 11, 2023) –  As an increasing number of improved asthma treatments are developed, a greater number of people with asthma are finding their symptoms under control. Their improved status raises an important question for healthcare providers (HCPs) who treat this condition: “What qualifies as clinical remission in the treatment of asthma?” A panel of 11 experts in asthma care came together to review available literature to create a working definition. The panel included six allergists, three pulmonologists and two pediatricians. The paper outlining their recommendations is published in Annals of Allergy, Asthma and Immunology, ...
