Why are some rocks on the moon highly magnetic?

Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud of ionized particles that briefly enveloped the moon and amplified its weak magnetic field.

Scientists have discovered a direct cause-and-effect link between faulty mitochondria and the memory loss seen in neurodegenerative diseases. By creating a novel tool to boost mitochondrial activity in mouse models, researchers restored memory performance, suggesting mitochondria could be a powerful new target for treatments. The findings not only shed light on the early drivers of brain cell degeneration but also open possibilities for slowing or even preventing diseases like Alzheimer’s. Read more

Scientists have engineered a groundbreaking cancer treatment that uses bacteria to smuggle viruses directly into tumors, bypassing the immune system and delivering a powerful one-two punch against cancer cells. The bacteria act like Trojan horses, carrying viral payloads to cancer’s core, where the virus can spread and destroy malignant cells. Built-in safety features ensure the virus can’t multiply outside the tumor, offering a promising pathway for safe, targeted therapy. Read more

Designed to help the body build functional dermis rather than scar tissue, the innovation combines fibroblast cells on gelatin beads with a hyaluronic acid gel, held together using click chemistry. In a parallel advance, the team also created elastic... Read more

These tiny architects not only build elaborate leaf nests but also double their pulling power when more ants join in. Using a “force ratchet” system where some pull while others anchor, they outperform the efficiency of human teams and could inspire revolutionary... Read more

Chemical evidence from a stalagmite in Mexico has revealed that the Classic Maya civilization’s decline coincided with repeated severe wet-season droughts, including one that lasted 13 years. These prolonged droughts corresponded with halted monument construction and political disruption at key Maya sites, suggesting that climate stress played a major role in the collapse. The findings demonstrate how stalagmites offer unmatched precision for linking environmental change to historical events. Read more

Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a precise sequence of laser pulses, the team can “tell” the quantum dots exactly how to emit light, making the process faster, cheaper, and more efficient. This advance could open the door to more practical quantum technologies, from ultra-secure communications to experiments that... Read more
