Nanomagnets offer clues to how avalanches work

The behavior of avalanches has generated interest among physicists for the insights that they can provide about many other systems, not least of which is how snow falls down a mountainside. To that end, a team of researchers ...

A traffic light for light-on-a-chip

Integrated photonics allow us to build compact, portable, low-power chip-scale optical systems used in commercial products, revolutionizing today's optical datacenters and communications. But integrating on-chip optical gain ...

Studying the edge of the sun's magnetic bubble

Our corner of the universe, the solar system, is nestled inside the Milky Way galaxy, home to more than 100 billion stars. The solar system is encased in a bubble called the heliosphere, which separates us from the vast galaxy ...

Modern simulations could improve MRIs

Gadolinium-based contrast agents, the gold standard in magnetic resonance imaging (MRI) to determine the health of a patient, can be improved, according to Rice University engineers who are refining models they first used ...

Exploring eruptions from the Sun

In our solar system, solar flares and coronal mass ejections (CME) are the most spectacular eruptive activities. Large solar flares and CMEs may bring us disastrous space weather, destroy our satellite and navigation system, ...

NASA model describes nearby star that resembles early sun

New research led by NASA provides a closer look at a nearby star thought to resemble our young sun. The work allows scientists to better understand what our sun may have been like when it was young, and how it may have shaped ...
