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.

An update

Since Donald Trump entered the White House for the second time, the U.S. import taxes faced by Morph, which supplies Walmart and Target, have lurched wildly—from zero tariffs to 20% tariffs to 50% tariffs, before briefly flirting with 145% tariffs. The figure fell back to 20%, before the Supreme Court intervention last week ruled the tariffs illegal, which brought them back down to zero. The president then announced a new 10% tariff, although there is some confusion about whether he actually means 15%.
