Researchers race against extinction to uncover tree’s cancer-fighting properties

Three Chinese fir trees on a nature reserve in southeastern China are the last of their kind. As their existence is threatened by human disturbance and climate change, researchers are hurrying to learn everything they can about the tree – which might inspire new and more effective ways to treat various cancers.

Earth has a few natural carbon sinks. Some of them are starting to fail.

Until humans can find a way to geoengineer ourselves out of the climate disaster we’ve created, we must rely on natural carbon sinks, such as oceans and forests, to suck carbon dioxide out of the atmosphere. These ecosystems are deteriorating at the hand of climate change, and once destroyed they may not only stop absorbing […]

Early humans likely took the coastal route to North America

When and how the first humans reached North America is a complicated puzzle. Scientists believe these people arrived in Alaska after crossing the Bering Strait, only to be stopped by the enormous Laurentide and Cordilleran ice sheets. The migrants would eventually make their way down to the Americas via one of two paths: the western […]

Study finds strong link between depression and opioid overdoses

The link between mental health disorders and substance abuse is well-documented. Nearly one in 12 adults in the U.S is depressed, and opioid-related deaths are skyrocketing. As these numbers continue to climb, some mental health professionals have started to wonder if there’s a link between the two. According to a new study published in Social […]

Millions of birds die in collisions each year, but these lights could change that

Millions of birds die each year in collisions with planes, and airports have used everything from fireworks to herding dogs to scare them away. Some methods have been relatively successful, but they’re useless after the plane takes off. Researchers at Purdue University may have just found a solution.

Meet the Purdue researcher exploring the Red Planet

One hundred forty million miles from Earth, cold winds whip dust harshly across the planet’s rocky surface. Clouds float through the thin atmosphere, and at night, two tiny moons shine in the sky. Though Mars looks like a desert now, many scientists believe water once flowed freely there, potentially fostering the development of microbial life.
