Streams of gas might lead to the rapid formation of high-mass stars

The size of our universe and the bodies within it is incomprehensible to us lowly humans. The sun has a mass that is more than 330,000 times that of our Earth, and yet there are stars in the universe that completely dwarf our sun.

Simple additive method leads to record-setting perovskite laser performance

For years, engineers have sought better ways to build tiny, efficient lasers that can be integrated directly onto silicon chips, a key step toward faster, more capable optical communications and computing.

Scientists program cells to create biological qubit in multidisciplinary research

At first glance, biology and quantum technology seem incompatible. Living systems operate in warm, noisy environments full of constant motion, while quantum technology typically requires extreme isolation and temperatures near absolute zero to function.

Optical resonator enables a new kind of microscope for ultra-sensitive samples

Everyone who ever took a photo knows the problem: if you want a detailed image, you need a lot of light. In microscopy, however, too much light is often harmful to the sample—for example, when imaging sensitive biological structures or investigating quantum particles. The aim is therefore to gather as much information as possible about […]

From pitcher plants to printing presses, study shows how sticky films can be tamed

A recent Cambridge study reveals why sticky liquids don’t always spread evenly, knowledge that could help cut waste, improve product quality and make everyday technologies more reliable.

Weak points in diamond fusion fuel capsules identified

Scientists at the University of California San Diego have uncovered how diamond—the material used to encase fuel for fusion experiments at the National Ignition Facility (NIF) in Lawrence Livermore National Laboratory—can develop tiny structural flaws that may limit fusion performance.

Ultrabroadband laser ‘comb’ can enable rapid identification of chemicals with extreme precision

Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify chemicals and pollutants with extremely high precision.

Falling water forms beautiful fluted films

When water drains from the bottom of a vertical tube, it is followed by a thin film of liquid that can adopt complex and beautiful shapes. KAUST researchers have now studied exactly how these “fluted films” form and break up, developing a mathematical model of their behavior that could help improve the performance, safety, and […]

New model describes result of non-reciprocal interactions between two non-linear molecules

Asymmetric interactions between different species of molecules have previously been demonstrated to result in self-organized patterns and functions. If one species A is attracted to B, but in turn, B is repelled by A, run-and-chase dynamic emerges.

Researchers develop novel miniaturized lidar technology based on cross dual-microcomb

Optical frequency combs, as a time and frequency “ruler,” have important applications in precision ranging. Conventional dual-comb ranging schemes utilize the optical Vernier effect to achieve long-distance measurements, and they typically require asynchronously secondary sampling, either after changing the repetition rates or swapping dual-comb roles.

Room-temperature reactor uses electrochemistry to boost nuclear fusion rates

Using a small bench-top reactor, researchers at the University of British Columbia (UBC) have demonstrated that electrochemically loading a solid metal target with deuterium fuel can boost nuclear fusion rates.

The most powerful tool in an astronomer’s arsenal is a lens—but not the kind you might think

Astronomers are living in a golden age of bigger and better telescopes. But even our most advanced technology pales in comparison to the power of nature’s own “cosmic magnifying glasses”—strong gravitational lenses.

We’ve been sending animals into space for 7 decades—yet there are still no rules to protect them from harm

This week, Russia is expected to launch its Bion-M No.2 biosatellite from the Baikonur Cosmodrome in Kazakhstan, carrying 75 mice and 1,500 fruit flies.

Watching how stars come into being using cosmic simulations

Pictures are the key to new insights in the field of astrophysics. Such images include simulations of cosmic events, which astrophysicists at UZH use to investigate how stars, planets and galaxies came into existence.
