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.
If you’ve been to your neighborhood farmers market or seen a small “local” section pop up in your grocery store, you may have noticed a trend: People want to know where their food is coming from, and the agricultural industry is responding.
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 […]
During the holiday season, it can be difficult for even the most determined of us to stick to a healthy diet. A piece of Halloween candy here, a pumpkin spice latte there, and suddenly we’re left feeling like we forgot what vegetables taste like.
Determining the structure of a virus is an important step in understanding and treating viral disease. For decades, structural biologists have been using cryo-electron microscopy to create increasingly accurate pictures of biomolecules, but one of the assumptions they’ve been relying on could be wrong.
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 […]
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 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.
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.
The explosions of stars, known as supernovae, can be so bright they outshine their host galaxies. They take months or years to fade away, and sometimes, the gaseous remains of the explosion slam into hydrogen-rich gas and temporarily get bright again – but could they remain luminous without any outside interference?
