The Red Planet has a purple side

Oxidized iron dominates the Martian color palette. The dusty reds, ochers, browns and tans give the planet its nickname: the Red Planet. But new images of Mars’ south polar region show something different. Swirls of pink, purple and red highlight the region and a feature named Thyles Rupes, an icy crag with cliffs higher than […]

Researchers measure the environment where the first supermassive black holes formed

When the James Webb Space Telescope pointed its powerful instruments toward the early universe, scientists were surprised by what it found. At high-redshift (z) values, corresponding to less than 1 billion years after the Big Bang, astronomers witnessed an abundance of galaxies that hosted what appeared to be the “seeds” of supermassive black holes (SMBHs). […]

X-ray light is like guitar music, with frequencies sliding continuously between harmonics

Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has developed a method that makes it possible to tune the frequency continuously.

Photonic Legos of functional 3D thin-films unlock high-performance heterogeneous photonic integration

Photonic integrated circuits route information with optical signals instead of relying only on electrical currents. Silicon (Si) and silicon nitride (SiNx) are excellent photonic platforms for waveguides, but they cannot efficiently perform the ever-increasing tasks required for fully integrated optical systems. A heterogeneous photonic integration platform capable of interfacing different optical materials with high performance […]

Cooling liquids reveal self-limiting particle clusters behind glass transition

Before diving into the mystery of glass, theoretical physicist Corentin Laudicina takes us back to high school physics for a moment. Although he has spent years studying exactly what happens in a material during the glass transition, he also understands that his research is not the easiest thing to explain off the cuff at the […]

Venus ate its moon: How Earth’s ‘twin’ could have swallowed a rocky satellite

Scientists have long speculated why Venus, with a size, mass and structure similar to Earth’s, doesn’t have a moon. New UC Riverside research shows that our hungry twin likely swallowed it.

To understand the solar cycle, notice how the sun sleeps

The sun is such a constant in our lives that it can be difficult to imagine our star ever changing. But the sun can be quite variable. There are times when its magnetic field is turbulent and generates many sunspots and other times when it is quiet and dormant. Since the 1800s, we’ve known that […]

Two-color light steers electrons through graphene’s transient topological state

The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape a material’s electronic band structure (i.e., the range of energy states available to electrons), potentially giving rise to new electronic behaviors.

Scientists simulate cosmic crashes to test whether icy moons gain or lose their ability to sustain life

Many of the moons orbiting Saturn, Uranus and Neptune likely conceal oceans of liquid water beneath miles of icy shell. Because life as we know it needs water, these buried oceans rank among the most promising places to search for life beyond Earth.
