Nonrepeating photonic crystal may enable more tunable, reliable semiconductor lasers

Over the past two decades, photonic-crystal surface-emitting lasers (PCSELs) have shown promise as a type of advanced semiconductor laser useful in defense- and aerospace-related applications. Typically, these devices are made with photonic crystal patterns that repeat across the area of the device. But new research from the lab of electrical and computer engineering professor Kent […]

‘Starwashing’: How space companies use the greenwashing playbook while causing environmental damage

From launchpads to low Earth orbit and beyond, space companies and their affiliates are deploying a familiar marketing tactic—with a new twist. In a space economy projected to reach US$1.8 trillion by 2035, they sell space exploration narratives by appealing to a desire to expand humankind beyond Earth—while downplaying or omitting the negative repercussions for […]

Airborne observatory improves views of solar corona during cloud-covered eclipse

Using unique equipment installed on NASA’s WB-57 aircraft flying above heavy clouds off the coast of Iceland, a Southwest Research Institute-led team successfully observed a total solar eclipse on Wednesday. The high-altitude jet followed the moon’s shadow at 50,000 feet (15,000 meters) to take measurements of the solar corona in nine different wavelengths, ranging from […]

Cell biochemistry beyond membranes: Condensate physics reveals general rules for chemical responses

Basic biology courses teach that cells contain organelles—such as the nucleus, mitochondria and Golgi apparatus—set apart by lipid membranes to get things done. Recent cell biology research has revealed another organizational principle at work in cells across all orders of biology.

Bound gravitational waves inspired by photonic systems

When one mentions “waves,” we immediately think of a perturbation that propagates. This applies to waves on the shore, sound waves in the air or electromagnetic waves that we use to transmit information via optical fibers. The same idea of propagating perturbations applies to gravitational waves (GWs), which entered the mainstream media a decade ago […]

Constipation is common in astronauts—blood tests provide new answers

For astronauts in space, constipation is a well-known problem. But why this happens has long been unclear. Now, a new study from the University of Copenhagen in collaboration with NASA provides an idea of what happens in the stomach without the influence of gravity.

Mysterious Cygnus Bubble may trace back to microquasar, astronomers suggest

Astronomers have proposed a new explanation for the mysterious Cygnus Bubble, a vast cloud of ultra-high-energy gamma rays stretching thousands of light-years across the sky. While the bubble has generally been linked to the Cygnus X star-forming region, the new study argues that a microquasar more naturally explains its highest-energy emission. The results were published […]

Controlling the rotation direction of light without complex new materials

A new pathway has opened for controlling the rotation direction of light simply by changing how molecules are arranged, without having to synthesize complex new materials. Circularly polarized light is a special form of light that travels while rotating like a pinwheel to the left or right. Because different rotation directions can carry different information, […]

Tiny satellite will use the dark side of the moon to eavesdrop on whispers from the early universe

A tiny UK-developed satellite, roughly the size of a small carry-on suitcase, could help answer one of the biggest questions in cosmology: What happened during the roughly 150 million years of the cosmic dark ages, before the universe’s first stars appeared?
