Have you ever heard someone comparing MPGs or wishing for better “mileage?” Miles per gallon (MPG) is the distance a vehicle can travel on one gallon of gasoline. Gas gets many of us where we need to go, but fumes from this fossil fuel pollute the air. Humans have burned an unprecedented amount of gas since the car was mass-marketed in the early 1900s. Fossil fuel air pollution is one major reason for climate change.
How do we use less gas—while still getting to school, work, and everywhere else? Well, some say electric vehicles (EVs) are the future. Others believe hybrids are the way forward.
EVs v. Hybrids
EVs are cars or trucks that run only on electricity. They’re also known as plugins, as they plug into charging stations to power upon electricity. A powerful battery stores the energy. On average, an EV has a range of over 100 miles (161 km) before the battery needs to be recharged; this process could be as short as dinner at a restaurant or longer than a full night’s sleep. Unless you live within a half day's drive of the Grand Canyon, an EV can’t take you there on a single charge.
Right now, electric vehicles face two big challenges. They have limited range and cost a lot—more, on average, than a gas-powered luxury car. The Tesla Model 3 (a well-known electric sedan) has a range of over 300 miles (483 km) and costs more than $47,000. A number of other car makers have EV models too.

Who's Your Cousin?
The great apes are among the most popular animals in most zoos. Their actions, facial expressions, and family life remind us so much of ourselves. Have you ever wondered, though, how we might look to them?
Is it possible to die of boredom?
To figure out if we can die of boredom, we first have to understand what boredom is. For help, we called James Danckert, a psychologist who studies boredom at the University of Waterloo in Canada.
THE PROBLEM WITH PALM OIL
Palm oil is all around you. It’s in sugary snacks like cookies and candy bars. It’s in lipstick and shampoo and pet food.

HUMANS AREN’T THE ONLY PRIMATES THAT USE MEDICATION.
THE LEFT OVERS
A lot has happened for modern humans to get to this point. We lost most of our hair, learned how to make tools, established civilizations, sent a person to the Moon, and invented artificial intelligence. Whew! With all of these changes, our bodies have changed, too. It’s only taken us about six million years.
SO, WHAT IS A PRIMATE?
What do you have in common with the aye-aye, sifaka, siamang, and potto? If you said your collarbone, you re probably a primatologist—a person who studies primates. If you’re not, read on.
