A mathematical puzzle solved, an ocean floor around Earth's core, innovations in architecture and more

World’s First Bio-Material Toilet Discreet and elegant, the Block is the world’s first bio-material toilet—made from a mixture of wood chips and resin. Produced by Finnish interiors brand Woodio and designed by Pentagram, the toilet eschews porcelain (which carries a larger carbon footprint) for an innovative wood that’s highly durable and waterproof. The Block is expected to last 10 to 15 years with the possibility …

Ancient Ocean Floor Discovered Around Earth’s Core

A new study published in Science Advances reveals that there’s an ancient sunken ocean floor in between the layer of the Earth’s mantle and its core. Scientists from the University of Alabama discovered this through global-scale seismic imaging that was collected over years, indicating ultra-low velocity zones (ULVs) or places with strong wave speed reduction, along the core-mantle boundary (CMB). “Analyzing 1000s of seismic recordings from …

Pentagon Says Extraterrestrials May Have Already Visited Earth

According to a draft document (which is under review) released by the Pentagon, intelligent extraterrestrial beings might have already visited Earth and even be monitoring life here via research devices—or probes. Written by Sean Kirkpatrick (director of the Pentagon’s All-Domain Anomaly Resolution Office) and Avi Loeb (chairman of Harvard’s astronomy department and founder of the Galileo Project), the research paper says, “Since most stars formed more than …
