CT scans of the world's rarest dodo skulls suggest the extinct bird may have had a stronger sense of smell, a highly sensitive beak, and a lifestyle that extended into dawn and dusk. The discoveries are helping overturn centuries-old myths and reveal ...

A rare meteorite that crashed through a New Jersey roof contains evidence of ancient salty fluids, organic compounds, and amino acids from a primitive asteroid. Its pristine chemistry could offer new clues about how space rocks helped supply early .. ...

A new nanostructured carbon design lets fuel-cell catalysts use tiny amounts of platinum while remaining remarkably stable and efficient. The breakthrough could help hydrogen fuel cells become a more practical way to power data centers, vehicles, and ...

Getting the recommended 150 minutes of moderate-to-vigorous exercise each week may offer only modest protection against heart attacks and strokes. A large study suggests that substantially greater benefits may require roughly 560 to 610 minutes a ...

A protein that evolved long before the human circulatory system may help unlock stronger cancer treatments. When C3 is produced inside tumors, it blocks immune-suppressing cells and gives immunotherapy a better chance to work. Researchers were even . ...

Scientists have created the first quantum material that can sort and transport different quantum states of light at room temperature, potentially removing the need for bulky, ultra-cold refrigeration systems. Built from a gold film carved with ...

Scientists have discovered incredibly tiny plasma whirlpools swirling across the Sun's surface, some just 20 kilometers wide. These previously invisible vortices may twist magnetic fields and help build up the energy released in small solar eruptions ...

Changing how much sweet-tasting food people eat may not change how much they crave or enjoy sweetness after all. In a six-month trial, researchers found that people assigned to high-, low-, or average-sweetness diets showed no meaningful differences ...

Scientists have generated quantum entanglement directly from sunlight, potentially offering a lower-energy alternative to the lasers normally used in quantum technology. Their outdoor experiment produced entangled photons with about 94% similarity to ...

Teens who start using cannabis may experience slower growth in memory, attention, language, and processing speed. Their abilities often developed normally at first, then began leveling off while nonusers continued improving. THC appeared to be the .. ...
