From an engineering perspective, a water tube boiler is defined by the fact that water or steam–water mixture flows inside the tubes while high-temperature flue gas passes outside the tubes. In ...

Your most durable prints could be hollow by design, because walls, skins, geometry, and bonding create strength without heavy ...

A surprisingly small detail in the skin may play an outsized role in how young skin looks and how well it repairs scars. Researchers say the clue is a microscopic structure found in humans, pigs, and ...

Miranda does not look like a typical small moon. The surface, seen in detail only once during Voyager 2’s flyby in 1986, carries scars that seem out of scale with its size. Wide fault systems cut ...

Comprehensive review reveals how nanostructure engineering can slash costs and boost durability for clean energy applications ...

Explore Europa's ice shell structure with a fascinating NASA cutaway view revealing cracks and voids extending hundreds of ...

New microwave measurements from NASA’s Juno spacecraft reveal Europa’s ice shell may stretch nearly 29 km (18 miles) deep, ...

Cartoons often suggest turtles wear shells like removable armor. Those stories show turtles stepping out, swapping shells, or treating them like clothing. Biology disagrees. A turtle shell is not an ...

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, providing key experimental data for understanding the structure of extremely ...

The European Space Agency has released new images of a rare "butterfly" crater on the Red Planet. The bug-like structure sports a pair of smooth, rocky wings, which were likely "fluidized" by buried ...

University of Queensland researchers visualized yellow fever virus particles at near-atomic detail, uncovering major structural differences between vaccine and virulent strains. The insights could ...
