Amid the ancient pomp and ceremony of the Vatican, former Cardinal Robert Prevost has emerged onto the balcony of St Peter’s Basilica as the first U.S.-born pope in history. He has taken the papal name of Leo XIV—a name that the vast crowd in St. Peter’s Square took up with a spontaneous chant of “Le-on-e," the Italian version of the Latin Leo. After a relatively short conclave, Pope Leo XIV appeared overwhelmed with emotion as the crowd in St. Peter's Square rapturously welcomed him. Now, Vatican insiders are guessing among themselves how much change to expect. Prevost, 69, hails from Chicago, Illinois, and has spent much of his career in South America. He is only the third pope in history to be an Augustinian friar, one of the followers of the rule of the fifth-century St. Augustine of Hippo who are known for pastoral care, education, and missionary work.

Mental health hacks are everywhere these days, but which ones are backed by science? Some are tried-and-true: exercise regularly and get plenty of sleep. Other approaches are not yet well understood, like taking magnesium supplements or plunging your body into frigid water. And then there are the methods that aren’t entirely legal (for now) like microdosing psychedelics. 😳 In a world where there’s not much you can control, find science-based tips you can put into practice immediately at the link in bio. #MentalHealthAwarenessMonth Photo by bryanschutmaat

Photo by joelsartore | Found throughout sub-Saharan Africa, the African hawk eagle plays an important role in the environment as a top predator and an umbrella species. To put it simply, when the African hawk eagle is protected, other species are as well. This means protecting the trees they need for nesting, the animals they need for food, and the plants and animals their prey need for sustenance. When the ecosystem is in balance, all species have the opportunity to thrive. Photo taken at Zoopark Zajezd in Czechia (the Czech Republic).

We're not sure what happened yesterday—we think a penguin stole our phone! Speaking of which, did you know that emperor penguins have adapted to live in one of the harshest environments on Earth? From diving off extraordinarily high cliffs to diving down to depths of over 1,600 feet (488 meters) in the ocean, these birds are capable of incredible feats of survival. Their hardiness is especially notable during nesting season, when females lay eggs in temperatures as low as minus 50 degrees Fahrenheit, and males can go nearly four months without food while incubating the eggs.
