A diamondlike structure gives some starfish skeletons their strength
Electron microscope images of knobby starfish’s calcite skeletons reveal an unexpected architecture that compensates for the mineral’s brittleness.
- Earth
Weird ‘superionic’ matter could make up Earth’s inner core
Computer simulations suggest that matter that behaves like a mash-up of solid and liquid could explain oddities of Earth’s center.
- Quantum Physics
The quantum ‘boomerang’ effect has been seen for the first time
Jostled particles return to their starting points in certain materials, an experiment reveals, confirming theoretical predictions.
- Animals
Vinegar eels can synchronize swim
Swarming, swimming nematodes can move together like fish and also synchronize their wiggling — an ability rare in the animal kingdom.

Materials of the last century shaped modern life, but at a price
From our homes and cities to our electronics and clothing, the stuff of daily life is dramatically different from decades ago.

An ‘everlasting’ bubble endured more than a year without popping
One of the bubbles, made with water, glycerol and microparticles, lasted 465 days before popping.
- Quantum Physics
Quantum particles can feel the influence of gravitational fields they never touch
A quantum phenomenon predicted in 1959, the Aharonov-Bohm effect, also applies to gravity.
- Quantum Physics
A century of quantum mechanics questions the fundamental nature of reality
A century after the quantum revolution, a lot of uncertainty remains.

Antiprotons show no hint of unexpected matter-antimatter differences
The ratio of electric charge to mass for protons mirrors that of their antimatter counterparts.
- Quantum Physics
Quantum physics requires imaginary numbers to explain reality
Quantum theory based only on real numbers fails to explain the results of two new experiments.
- Astronomy
The only known pulsar duo sheds new light on general relativity and more
Einstein was right, among other insights gleaned from watching a one-of-a-kind system of two pulsating dead stars for 16 years.
