The Hidden Language of Forest Elephants

Forest elephants are far chattier than they let on. Instead of the loud trumpeting we usually picture, they spend most of their time making deep, low-frequency rumbles that fall below what our ears can pick up. Stand close by, and you might feel a faint vibration in the air, but hear nothing at all.

In the rainforests of the Central African Republic, researchers with Cornell’s Elephant Listening Project have spent years recording this hidden world. Their microphones now hold close to one million hours of sound, gathered across about 460 square miles of dense forest. Bit by bit, scientists are building a kind of dictionary, matching specific calls to what the elephants are doing and who they are with.

The recordings do more than satisfy our curiosity. Because the same dense forest that hides elephants also hides poachers, the microphones pick up telling sounds:

• Rumbles that reveal where herds are gathering

• Gunshots that flag likely poaching

• Patterns that help rangers plan their patrols

If you want to listen in, the project shares its recordings and research online. It turns out that paying close attention, even to sounds we cannot hear, is one quiet way to help keep these elephants safe.

What Nobody Tells You About the Air in Your Home

You probably think of air pollution as something that happens outside, on busy highways or near factories. But the air inside your home can actually be more polluted than the air on the street, and most of us have no idea.

The culprits are surprisingly ordinary. Cooking on a gas stove, spraying a cleaning product, bringing home a new piece of furniture, even burning a candle, all of these can quietly add to what you're breathing every day. And because modern homes are so well-sealed and energy efficient, those particles don't have anywhere to go.

Your bedroom might be the sneakiest offender. If you regularly wake up with a stuffy nose, a dry throat, or that groggy feeling even after a full night of sleep, your bedroom air could be part of the reason. We spend about a third of our lives asleep in rooms with the windows closed, and dust, allergens, and chemical particles can build up overnight without you realizing it.

The fix doesn't have to be complicated. Running the fan when you cook, swapping harsh cleaners for gentler options, and keeping up with your air filters are all easy places to start. A diffuser with clean, natural scents can also help you create a fresher-feeling atmosphere without adding synthetic chemicals to your air. It's one of those quiet upgrades that makes everyday life feel a little bit better.

How to Host the Perfect Pizza Party

If you want a low-stress way to gather friends this summer, it’s hard to beat a pizza party. Everyone loves it, it’s endlessly customizable, and most of the real work happens before anyone shows up.

The trick is to set up a build-your-own pizza bar and let guests handle the fun part. You make the dough and sauce, then lay out bowls of toppings so everyone can design their own. A few crowd-pleasers to set out:

• Classics like pepperoni, mushrooms, and fresh basil

• Something unexpected, like figs, hot honey, or arugula

• A good melting cheese and a sauce or two

Store-bought dough is completely fair game and saves you the most stress. If you have a grill or a pizza stone, get it good and hot so the crusts cook fast and crisp. Set everything out before guests arrive so you aren’t stuck in the kitchen while the party happens without you.

Add a simple green salad and something cold to drink, and you’re set. For a full game plan, check out more hosting tips worth borrowing.
