More screen time during infancy and around the start of school was linked to poorer academic performance and weaker working memory years later. The findings suggest that early childhood may contain particularly sensitive windows when screen habits .. ...

Researchers have found a way to create a complete 3D image of a molecule's wavefunction, one of quantum mechanics' most fundamental yet elusive features. By combining advanced photoelectron measurements with newly designed algorithms, the University ...

NASA's Roman Space Telescope has been cleared for final launch preparations ahead of a targeted August 30 liftoff aboard SpaceX's Falcon Heavy. The powerful new observatory will probe cosmic expansion, the history of the universe, and distant ...

The Artemis II crew will receive the Congressional Space Medal of Honor after becoming the first humans in more than 50 years to travel beyond the Moon. Their 10-day Orion mission also carried them farther into space than anyone in history.

Scientists discovered a small, yellowish mountain horned dragon in Thailand and named it Acanthosaura syrax after a dragon from House of the Dragon. Found only in a narrow band of high-elevation forest, the distinctive new species could become a ...

Gut bacteria can transform nitrate and plant-based iron from vegetables and other foods into protective molecules that may benefit the heart and metabolism. In experimental models, higher levels of these compounds were linked to lower blood pressure, ...

Researchers have uncovered a possible reason why the Alzheimer's risk gene APOE4 can disrupt the brain long before memory problems begin. In mice, APOE4 increased a protein called Nell2, shrinking neurons and making memory circuits unusually active. ...

An abandoned farm field became a flourishing wildflower meadow within little more than a decade, with plant diversity doubling and thousands of orchids appearing naturally. The discovery suggests that simply giving nature time to recover could be a . ...

Researchers have found a way to slash the processing time for 3D-printed zirconia crowns from as much as 100 hours to under 30 minutes. The advance could eventually let dentists print strong, customized permanent crowns for patients within a single . ...

Researchers at CERN have created microscopic versions of the early Universe by colliding surprisingly small atomic nuclei at nearly the speed of light. The collisions produced quark-gluon plasma, the ultra-hot matter believed to have filled the ...
