Dogs act like toddlers when you need help - but cats just watch. Scientists compared 3 groups: pet dogs, cats, and human toddlers in an experiment where a human parent hides and pretends to look for an object. 75% of dogs and children helped. Cats only helped if it was in their personal interest.

Carbon dioxide overload, detected in human blood, suggests a potentially toxic atmosphere within 50 years. After this time, elevated atmospheric carbon dioxide, leading to CO2 accumulation in the body, has the potential to cause a range of adverse health effects.

Women report being slightly more sexually satisfied than men, revealing a surprising gender trend. Relationship satisfaction doesn't fully explain why women are more sexually satisfied than men. Women's tendency to report higher satisfaction might be influenced by socialization and disclosure norms.

The Biden administration enacted over $198 billion in clean energy projects, the largest investment of its kind. People who lived close to the renewable energy and green manufacturing facilities noticed the investments, but were more likely to credit governors for it than the Biden administration.

Young people see fewer win-win situations than older people. Zero-sum beliefs assume that if one person succeeds, others must fail. On average, older adults are also more financially secure than younger ones, which can contribute to this age-related difference.

Left-handers are more competitive than right-handers. Most people are right-handed, but 10.6% are left-handed. Left-handers are rarer than right-handers, making their attacks in a combat situation more surprising than those of right-handers. This may help explain the evolution of left-handedness.
