Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, ...

Physicists have directly visualized the fundamental electronic building blocks of flat-band quantum materials, a class of systems in which electron motion is effectively quenched and strong ...

Scientists have uncovered the oldest direct evidence yet that Earth’s tectonic plates were on the move 3.5 billion years ago. By analyzing magnetic fingerprints in ancient rocks, they reconstructed ...

Abstract: The problem of angular velocity estimation for a rigid body directly from body-referenced vector measurements is addressed. The case of multiple (at least a pair of) vector measurements is ...

Animals come in an extraordinary range of body shapes. A starfish looks nothing like an earthworm, a mouse, or a human. Yet even closely related species can appear radically different: corals, ...

Today's sea level rise is significant enough to slow the rotation of the planet by just over a millisecond per century.

Cats rarely crash and burn, always seeming to land on their feet. But how? Researchers have uncovered the secret behind their midair control.

These long E. coli cells can swim their way into tubes, like catheters, so DeCurtis et al. studied the dynamics of elongated ...

The secret to this acrobatic skill lies in an extremely flexible part of the spine that allows cats to twist in the air and land safely.
