FRASCATI, Italy — Observing Earth from space provides a much-needed insight into the evolution of our planet's health. This is particularly important in the face of climate change , as environmental degradation, food insecurity and extreme weather events can all reveal themselves in stark images taken from high above our planet's surface. Simonetta Cheli is the director of Earth observation progr

Archaeologists have unearthed an 11th-century wooden kitchen gadget with an ancient board game carved into the back. Medieval bakers may have used the wooden paddle not just to transfer bread into an oven but also to pass the time while they waited for the food to cook, the researchers said. "We discovered a fragment of a fairly large shovel," Sergey Toropov , director of Novgorod State Universit
A gene variant called APOE4 dramatically increases the risk of late-onset Alzheimer's disease, the most common form of dementia. Now, emerging research is revealing APOE4's true role in the condition, and a new study pinpoints a possible way to treat it. Historically, scientists studying Alzheimer's disease have focused on two proteins that accumulate in patients' brains: amyloid-beta and tau. Ho
A drone powered by artificial intelligence (AI) has completed a championship race course faster than some of the world's best human drone pilots. In a study published Oct. 14 in the journal Science Robotics , scientists created an AI system capable of pushing a quadcopter through a demanding course at over 60 mph (100 km/h), using little more than a single forward-facing camera, an inertial measu
Tesla has unveiled a new "flying" version of its Roadster electric vehicle (EV) that uses SpaceX tech to pull off seemingly impressive airborne acrobatics. During a filmed demonstration at the SpaceX rocket testing facility in Texas Thursday (Oct. 15), the second-generation Tesla Roadster was shown accelerating up a curved ramp before launching itself into the air, performing a 180-degree barrel
Archaeologists have unearthed a Roman military camp in Spain, where they found fragments of weapons and metal tacks from soldiers' shoes. The camp was used during the Cantabrian Wars fought by Emperor Augustus as he expanded the Roman Empire in the first century B.C. The fortified military camp is made up of an earthen platform roughly 39 feet (12 meters) wide, which is surrounded by a stone peri

Rising temperatures around the globe are contributing to a range of health risks, from infectious disease to food insecurity and wildfire smoke . Extreme heat is another major public health concern, as climate change drives up both average temperatures and the frequency of extremely hot days. This August was the world's hottest on record , and it drove upticks in heat-related emergency visits and

Aging is one of the biggest risk factors for developing glaucoma or cataracts — but as scientists look more closely at what happens to the eyes over a lifetime, they are finding that people's exposure to air pollution also plays a role in whether they develop these eye conditions. Glaucoma, which affects about 80 million people worldwide , is a group of diseases that damage the optic nerve, which

When millions of people died in Europe during the Black Death, biodiversity suffered too, new research suggests. The findings suggest that human activities once promoted biodiversity in the landscape — and experts say we could use these findings to boost biodiversity in our modern agricultural landscapes. The 14th century was a tumultuous time for the people of Europe. Persistent cold, wet weathe

Like their cephalopod cousins the octopuses , cuttlefish are masters of disguise. As they hunt, these marine predators send waves of color across their skin. The rainbow display stops prey in their tracks, granting the cuttlefish just enough time to shoot out two specialized hunting tentacles at lightning speed and snatch them into range of their deadly beaks. But can cuttlefish actually mesmeriz
When temperatures spike, California redwoods slow down photosynthesis, new research has found. This finding has serious implications for the long-term survival of the iconic trees in a warming world, and their role in storing carbon from the atmosphere. California redwood ( Sequoia sempervirens ) forests are among the largest aboveground carbon stores on the planet. These towering trees are nativ
