A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn ...

The essential amino acid leucine can boost cellular energy production by protecting key proteins on mitochondria from being destroyed. The discovery reveals a new connection between nutrition and metabolism that could eventually lead to new ...

Mysterious 97-million-year-old magnetic fossils may be the oldest evidence of an animal using Earth's magnetic field like a built-in GPS. Their sophisticated magnetic structure could have helped an unknown ocean creature navigate thousands of ...

Researchers say stress on Southern California's San Andreas and San Jacinto faults has reached some of the highest levels seen in a 1,000-year simulation. Because both faults are highly stressed at the same time, the Cajon Pass junction may be ...

Scientists may have found a clue to one of the biggest mysteries surrounding the origin of life: how fragile RNA molecules could gather and survive before cells existed. New research shows that RNA is unusually good at assembling into tiny liquid ...

Scientists have identified two new species of large Australian stick insects, including one that lays extraordinary "lidded" eggs never before recorded in the group. The discovery also revealed that a familiar stick insect had been misidentified for ...

A new protective fabric boosted strawberry yields by as much as 3.56 times while blocking insects and still allowing sunlight, rain, and airflow to reach the plants. Originally inspired by research on military clothing, Plant Armor could also help .. ...

Marine heatwaves may be only the most intense part of much longer warming events, with elevated temperatures sometimes lingering for months. Researchers found that conventional measurements underestimate total heat exposure by more than 150% on ...

Mulberry compounds may reshape the gut microbiome in ways that support intestinal health and metabolism, with some combinations showing especially strong effects in animal studies. However, the results vary depending on the plant part and processing ...

Mount Vesuvius' famous 79 CE eruption has given scientists a remarkably precise benchmark for dating events deep in Earth's past. The improved technique could sharpen the timelines of volcanic eruptions, asteroid impacts, extinctions, and other major ...
