Phys.org / Olives have been essential to life in Italy for at least 6,000 years—far longer than we thought

How far back does the rich history of Italian olives and oil stretch? My new research, published in the American Journal of Archaeology, synthesizing and reevaluating existing archaeological evidence, suggests olive trees ...

Dialog / Infrared running of gravity offers a field-theoretic route to dark matter phenomena

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose ...

Phys.org / New 3D map of the sun's magnetic interior could improve predictions of disruptive solar flares

For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical Journal Letters, should ...

Phys.org / Electron-phonon 'surfing' could help stabilize quantum hardware, nanowire tests suggest

That low-frequency fuzz that can bedevil cellphone calls has to do with how electrons move through and interact in materials at the smallest scale. The electronic flicker noise is often caused by interruptions in the flow ...

Phys.org / When continents try, and fail, to break apart

Great things can come from failure when it comes to geology. The Midcontinent rift formed about 1.1 billion years ago and runs smack in the middle of the United States at the Great Lakes. The rift failed to completely rupture, ...

Medical Xpress / Humans show bat-like skills using mouth-click echolocation

It may sound like a scene from "Nosferatu," but research from the University of East Anglia shows that humans can use bat-like echolocation skills to judge the distance of objects. The new study reveals that, just like bats ...
