In a surprising discovery, scientists found that certain diets associated with obesity can make cancer immunotherapy more effective in mice, challenging traditional assumptions about diet and cancer treatment. The findings suggest that the secret may lie in how food interacts with gut bacteria to strengthen the immune system's response to cancer.
Researchers have developed an artificial intelligence (AI) model to generate realistic panoramic images for virtual tourism. The work has potential applications in cultural heritage preservation and destination marketing, the team suggests. Details are reported in the International Journal of Information Quality.
Astronomers have determined that VVV CL001, a metal-poor globular cluster near the center of the Milky Way, is about 13.4 billion years old, making it one of the oldest known star clusters in our galaxy. The cluster lies behind thick clouds of interstellar dust, which made its distance and age difficult to establish. The paper, outlining the methodology for estimating its age and distance, was posted to the arXiv preprint server on Oct. 20. It has been accepted for publication by Astronomy & Astrophysics.
NASA’s Perseverance rover has set a historic record by traveling 28.10 miles across Mars, farther than any vehicle has ever driven on another world. Armed with groundbreaking autonomous navigation technology and increasingly advanced driving capabilities, the rover is pushing the boundaries of robotic exploration.
NASA satellites have captured an eerie, skull-shaped formation on a remote Antarctic island, but its haunting appearance conceals a troubling warning about melting glaciers. Unusually warm winter temperatures have exposed large areas of dark ice, potentially accelerating future melting and gradually transforming the skull's ghostly features.
Scientists have uncovered surprising DNA evidence that Europeans living more than 30,000 years ago were connected across vast distances, challenging the idea that ancient populations remained largely isolated. Genetic clues from human remains and cave sediments reveal prehistoric migration, long-lasting communities, and survival through the harshest conditions of the Ice Age.
A major new study challenges the idea that moderate drinking is safe, finding that even relatively small amounts of alcohol increase the risk of cancer, heart disease, and premature death. Researchers found no overall health benefits from drinking and warn that consuming more than one alcoholic beverage per day can significantly increase long-term health risks.
NASA’s Hubble and James Webb Space Telescopes have uncovered surprising clues about the solar system’s origins by studying 27 tiny, distant objects beyond Neptune. Scientists discovered that these ancient building blocks of planets have remained remarkably unchanged for billions of years, while their unexpected sizes and numbers challenge existing theories of planet formation.
A major new review challenges the growing enthusiasm for medical cannabis as an insomnia treatment, finding little reliable evidence that it improves sleep quality, sleep duration, or daytime functioning. Researchers caution that this doesn't mean cannabis is ineffective, only that existing studies are too weak to establish whether it works.
Tucked away among its sensors, cameras and navigation tools, NASA's Mars rover Perseverance is wearing small swatches of spacesuit material. A rover doesn't need a spacesuit, but the swatches—each less than a square inch (6.5 square centimeters) in size—serve an important purpose: They're helping scientists assess the potential damage caused by ubiquitous Martian dust.
