San Andreas Fault-like Tectonics discovered on Saturn moon Titan

Strike-slip faulting, the type of motion common to California’s well-known San Andreas Fault, was reported recently to possibly occur on Titan, Saturn’s largest moon. New research, led by planetary scientists from the University of Hawai’i at Mānoa School of Ocean and Earth Science and Technology (SOEST), suggests this tectonic motion may be active on Titan, deforming the icy surface.

On multiple ocean worlds, for example Jupiter’s Europa and Saturn’s Enceladus, expressions of strike-slip faulting are well documented...

How the Brain Ignores Distracting Information to Coordinate Movements

The latest research has implications for understanding sensory disorders and building better prosthetics and robots that can fine-tune their movements based on what they touch. Researchers have discovered how neurons in a small area of the mammalian brain help filter distracting or disruptive signals — specifically from the hands — to coordinate dexterous movements. Their results may hold lessons in how the brain filters other sensory information as well.

As you read this article, touch receptors in your skin ar...

Molecular Mixing Creates Super Stable Glass

Researchers at Chalmers University of Technology, Sweden, have succeeded in creating a new type of super-stable, durable glass with potential applications ranging from medicines, advanced digital screens, and solar cell technology. The study shows how mixing multiple molecules – up to eight at a time – can result in a material that performs as well as the best currently known glass formers.

A glass, also known as an ‘amorphous solid’, is a material that does not have a long-range ordered structure — it does not form a crystal...

Some of the Biggest Asteroids in our Solar System

undefined

Astronomers have imaged 42 of the largest objects in the asteroid belt, located between Mars and Jupiter. The observations reveal a wide range of peculiar shapes, from spherical to dog-bone, and are helping astronomers trace the origins of the asteroids in our Solar System.

Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile, astronomers have imaged 42 of the largest objects in the asteroid belt, located between Mars and Jupiter. Never before had such a large group of asteroids been imaged so sharply. The observations reveal a wide range of peculiar shapes, from spherical to dog-bone, and are helping astronomers trace the origins of the asteroids in our Solar System.

The detailed images of these 42 objects are a leap forward in exploring asteroids...
