Phys.org / 'Heel-strike' may have allowed early humans to walk farther—at the cost of high-impact forces

The average person takes thousands of steps each day, instinctively walking heel-to-toe. Although they hardly register them, those consistent heel-first strides are more distinctive to humans than previously thought and allowed ...

Phys.org / Do black holes have hidden hair? Scientists find a new way to check

When two black holes crash together and merge, the newly formed black hole rings like a bell, sending out gravitational waves with specific frequencies that fade over time. This brief, fading pattern of waves is called ringdown, ...

Phys.org / Bumpy battery surfaces can masquerade as nanoscale ion pathways, misleading material design

A signal that appears to show ions moving inside a battery may, in fact, be an illusion caused by an uneven surface. A KAIST research team has identified the origin of this type of artifact, which can lead researchers to ...

Phys.org / Slender crystal's blue-to-yellow glow could make invisible forces visible

Applying pressure to luminescent organic crystals usually brings molecules closer together and weakens their fluorescence. Materials that instead brighten and undergo a large color change are rare, and clear design principles ...
