Discovering the physics behind 300-year-old firefighting methods

Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors analyzed the pressure chamber’s Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), …

Self-powered movable seawall for tsunami protection and emergency power generation

A movable seawall system, capable of generating sufficient electricity to raise gates and protect ports against tsunamis, has been proposed by researchers. The system has been found feasible in areas prone to Nankai Trough earthquake tsunamis. Additionally, it can generate surplus energy to supply emergency power to ports during power outages that commonly occur in …

Records of cometary dust hitting the asteroid Ryugu

The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region. ​The Hayabusa2 mission that collected samples from the asteroid Ryugu has …

Newborn great white shark possibly seen in the wild for the first time

Drone footage filmed off the coast of California shows a 1.5-metre-long, entirely white great white shark pup, probably just hours old – something that has never been seen before ​Drone footage filmed off the coast of California shows a 1.5-metre-long, entirely white great white shark pup, probably just hours old – something that has never …
