    Genomic study identifies human, animal hair in ‘man-eater’ lions’ teeth

    In 1898, two male lions terrorized an encampment of bridge builders on the Tsavo River in Kenya. The infamous Tsavo “man-eaters” killed at least 28 people in the camp before the civil engineer on the project shot them dead. The lions’ remains were sold to the Field Museum of Natural History in Chicago in 1925.

    In a new study, Field Museum researchers collaborated with scientists at the University of Illinois Urbana-Champaign on an in-depth analysis of hairs carefully extracted from the lions’ broken teeth. The study used microscopy and genomics to identify some of the species the lions consumed.

    Report: Conscientiousness, not willpower, is a reliable predictor of success

    According to two psychologists, the field of psychological science has a problem with the concept of self-control. It has named self-control both a “trait” — a key facet of personality involving attributes like conscientiousness, grit and the ability to tolerate delayed gratification — and a “state,” a fleeting condition that can best be described as willpower. These two concepts are at odds with one another and are often confused, the authors report.

    Study tracks decades of extreme heat, cold in Upper Midwest

    Researchers analyzed meteorological data from nine Upper Midwest states from 1979-2021, tracking trends in extreme heat and cold over every 4-kilometer square of that territory. They found striking regional differences in the extremes. Many parts of the Upper Midwest experienced significant upticks in the number of extreme heat days over the 40 years — an increasing trend — while others saw a rise in extreme cold events. Some communities experienced more of both extremes. Others appeared to be more resistant to changes in extreme heat or cold.
