Holography Breakthrough Turns Crosstalk Into Signal for Truly Continuous 3D Displays
For decades, the dream of projecting a fully three-dimensional image into empty space has been constrained by an inconvenient truth of physics: light refuses to...
Microscopic robots now sense heat and pump fluid to reshape their surroundings
In the natural world, organisms and their environments are locked in a constant conversation. Termites build nests that alter airflow and humidity, which in turn...
Chloride Trick Yields Ultrathin Intermetallic and High-Entropy Alloy Crystals
For two decades, the world of two-dimensional materials has been dominated by substances that naturally flake apart into atomically thin sheets: graphite, molybdenum disulfide, and...
Swinging Blood Pressure May Silently Fuel Deadly Aneurysms, Giant Study Finds
For decades, doctors have judged blood pressure risk by a single, deceptively simple number: the average. But a sweeping new study drawing on nearly 190,000...
Tiny Robotic Cilia Sense Heat and Pump Fluid on a Chip
A quiet revolution is unfolding at the scale of a human hair. In work highlighted in a News and Views piece by Wenqi Hu of...
Heart-on-a-Chip Pumps Blood-Style Flow to Test Drug Effects on Beating Cells
Every heartbeat is a conversation between chemistry and mechanics, and it happens in a moving stream of blood. When a drug enters the circulation, it...
New US Dietary Guidelines Could Push Food Emissions Up by a Third, Study Finds
