Deep-sea sponge's 'zero-energy' flow control could inspire new energy efficient designs

The Venus flower basket sponge, with its delicate glass-like lattice outer skeleton, has long intrigued researchers seeking to explain how this fragile-seeming creature's body can withstand the harsh conditions of the deep ...

Using DNA origami, researchers create diamond lattice for future semiconductors of visible light

The shimmering of butterfly wings in bright colors does not emerge from pigments. Rather, photonic crystals are responsible for the play of colors. Their periodic nanostructure allows light at certain wavelengths to pass ...

Remains of two men from central China shed light on ancient practice of punitive amputation

It's a scene straight out of a mystery novel: The skeletons of two unrelated men show signs of remarkably similar injuries. One is missing about one-fifth of his lower left leg, while the other is missing the same length ...

The observation of a Spin Berry curvature-enhanced orbital Zeeman effect in a kagome metal

In solid materials, magnetism generally originates from the alignment of electron spins. For instance, in the ferromagnet iron, the overall net magnetization is prompted by the alignment of spins in the same direction.
