Mathematicians have uncovered what they argue is a fundamental flaw in the standard model of the universe, potentially challenging the need for dark energy. Their calculations suggest that the mathematical framework used to describe cosmic expansion ...

Getting more daylight could be linked to a surprisingly powerful benefit for brain health. In a study of more than 87,000 adults, researchers found that higher daytime light exposure was associated with a 16% lower risk of dementia, with longer ...

Ancient ice discovered high in Tibet may be more than 128,000 years old, preserving an extraordinary record of Earth's climate that scientists previously thought had been lost. The discovery reveals a rare glimpse into the last ice age and could ...

Researchers have discovered a small group of brain cells that prevents dangerous blood pressure swings, even when average readings appear normal. The finding reveals a hidden source of cardiovascular risk and could open the door to new treatments ...

Scientists have defied a long-standing rule of laser physics by generating X-rays with much higher energies than conventional theory predicts. The surprising discovery reveals how two electrons working together can overcome a previously accepted ...

Scientists have uncovered seven surprising stages that space rocks go through as they hurtle toward Earth, revealing that melting and violent fragmentation, rather than simple evaporation, determine their fate. The discovery could help explain why .. ...

Scientists have discovered that magma deep inside Earth can store surprising amounts of extra oxygen, potentially revealing a hidden contributor to our planet's oxygen-rich atmosphere. The findings suggest that ancient volcanic eruptions may have ...

Researchers have discovered a surprising hidden ability in Europe's familiar black-and-yellow fire salamanders: they glow green and cyan under ultraviolet light. The mysterious fluorescence comes mainly from glands in their skin and their toxic ...

Scientists have uncovered a long-lost volcanic system in Iran that dates back roughly 100 million years, revealing a hidden chapter in Earth's tectonic history. The discovery sheds new light on the disappearance of an ancient ocean and the powerful . ...

Scientists have uncovered a surprising connection between Earth's opposite poles that may help explain how the planet plunged into past ice ages. New research suggests that as massive ice sheets expanded across the Northern Hemisphere, they cooled .. ...
