Phys.org / Earth's crust under stress: Researchers decipher energy release during earthquakes

Why do some earthquakes release more energy than others? A research team led by Prof. Dr. Armin Dielforder from the University of Greifswald has managed to demonstrate a clear physical connection between the energy released ...

Phys.org / When the air gets dry, cockroaches cuddle: Study reveals survival strategy

When conditions get too dry, Madagascar hissing cockroaches like to "cuddle." Under certain conditions, the large insects gather in groups, with many participants in physical contact with one another. According to recent ...

Phys.org / Mirror symmetry prompts ultralow magnetic damping in 2D van der Waals ferromagnets

Two-dimensional (2D) van der Waals (vdW) ferromagnets are thin and magnetic materials in which molecules or layers are held together by weak attractive forces known as vdW forces. These materials have proved to be promising ...

Phys.org / An electric discovery: Pigeons detect magnetic fields through their inner ear

In 1882, the French Naturalist Camille Viguier was among the first to propose the existence of a magnetic sense. His speculation proved correct. Many animals—from bats, to migratory birds and sea turtles use the Earth's ...

Phys.org / Why some volcanoes don't explode

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped while the magma was ...

Phys.org / Plant breeding discovery could pave way for new crop species

One of the great mysteries in plant biology is how, given the clouds of pollen released by dozens of plant species all at the same time, an individual plant can recognize which particular species' pollen grains will induce ...

Phys.org / Theia and Earth were neighbors, new research suggests

About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly happened afterward has ...

Phys.org / Mystery of how turtles read their magnetic map solved—they feel the magnetism

Loggerhead turtles are able to sense Earth's magnetic field in two ways, but it wasn't clear which sense the animals use to detect the magnetic field when navigating using the magnetic map they are born with. Now researchers ...

Phys.org / Could a kid have painted that? Jackson Pollock's famous pour-painting has child-like characteristics, study shows

What makes art art? Is it the method or the creator? Does it need a color palette and oil paints, or a canvas laid flat on the floor and paint splattered across it? Does it require a critically acclaimed painter, or a toddler ...

Phys.org / Bright squeezed vacuum reveals hidden quantum effects in strong-field physics

In a new study published in Nature Physics, researchers have demonstrated that quantum light, particularly bright squeezed vacuum (BSV), can drive strong-field photoemission at metal needle tips.

Phys.org / Climate change is now warming the deepest parts of the Arctic Ocean

While it is well known that climate change is heating the world's oceans, it was thought that the deep sea was safe from its effects—until now. Researchers have discovered that a rapidly warming part of the Atlantic is ...
