Machine Learning Detects Hidden Self-Harm History in Veterans' Records
University of North Carolina (UNM) researchers have utilized machine learning to detect instances of self-harm history that were not captured in standard medical records. A study of over 1.3 million patients revealed that diagnosis codes only captured approximately one-fourth of clinically documented self-harm history.
Political Anger and Support for Violence
Political anger can fuel support for violence, particularly when voters feel ignored by the political system. Conversely, when people perceive the government as responsive to their concerns, this can act as a buffer against endorsing political violence. This phenomenon was observed among both Democrats and Republicans during the 2024 US presidential election.
Growing Liquid Fuel from Sunlight Using Engineered Leaves
A research team led by Yale chemists has achieved a significant advancement in artificial photosynthesis by creating a device that produces methanol, a liquid fuel, using sunlight, water, and carbon dioxide. This mimics the natural process of photosynthesis in plants.
Christian Beliefs and Reproductive Rights/Population Growth
Strong adherence to Christian beliefs regarding divinely ordained roles for men and women is strongly linked to support for national population growth and restrictions on reproductive rights. These religious views significantly shape family dynamics and preferences for government policies.

These masking behaviors can include pretending to pay attention, suppressing fidgeting, rehearsing conversations, and over-preparing for meetings.
Fear and Social Pressure Driving Gun Ownership
The increasing prevalence of gun ownership in the US is partly driven by fear and social pressure, with individuals feeling compelled to arm themselves due to concerns about being the only unarmed person in a potential confrontation.
