Rebooting a forgotten battery. Over a century ago, Thomas Edison designed a rugged nickel-iron battery for early electric cars. It never caught on. But now, researchers are revisiting that forgotten design using modern nanotechnology. Their updated version can charge in seconds and survive roughly 12,000 cycles, raising the possibility that a practically ancient invention could help solve one of today's biggest energy problems: how to store renewable power at scale.
After analyzing 385 studies related to coastal areas and sea level rise, scientists found a significant discrepancy between geoid measurements and actual sea levels, especially in the global south.
Scientists trained a brain organoid to solve a well-known engineering task, and its success demonstrates the increasing complexity of lab-grown brains.
