When good governments go bad

Researchers found that societies with good governance, characterized by equitable power and wealth distribution, tend to collapse more thoroughly than autocratic regimes. Leaders who abandon core principles and moral guidelines can destabilize their societies, leading to a loss of citizen confidence and fiscal health.

Study reveals kidney disease or injury is associated with much higher risk of mortality for COVID-19 patients in ICU

Researchers found that patients with chronic kidney disease (CKD) or acute kidney injury (AKI) due to COVID-19 had significantly higher mortality rates in intensive care, with mortality rates ranging from 21% for those without kidney injury to 86% for patients with kidney transplants. The study highlights the need for calibration of IC...

Are climate scientists being too cautious when linking extreme weather to climate change?

Researchers argue that current approaches to attributing extreme weather events to global warming focus too much on raising the threshold for false alarms, neglecting the importance of accurate warnings. By prioritizing probability of detection, climate scientists can strike a better balance between caution and timely warning.
