It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes -- the biological catalysts in all living organisms -- form or break chemical bonds. ...

Using a scanning tunneling microscope equipped with a femtosecond terahertz laser, scientists have exploited the quantum properties of a two-atom hydrogen molecule to observe changes in the electrostatic field of a target sample, turning the hydrogen molecule into a quantum sensor. ...

Researchers have used the singing saw to demonstrate how the geometry of a curved sheet, like curved metal, could be tuned to create high-quality, long-lasting oscillations for applications in sensing, nanoelectronics, photonics and more. ...

Researchers have successfully developed a novel optical fiber design allowing the generation of rainbow laser light in the molecular fingerprint electromagnetic region. This new optical fiber with a self-cleaned beam can help in developing applications to, for example, tagging pollutants, cancer...

Technetium-99m is the world's most commonly used medical radioisotope, but regularly suffers from supply chain shortages, threatening the ability of doctors to diagnose a raft of ailments. But an alternative production technique looks set to make the radioisotope much more easily produced. ...

Scientists have succeeded in visualizing crystal nucleation -- the stage that precedes crystallization -- that was invisible until now. ...

Researchers have developed a sensor made of sapphire fiber that can tolerate extreme temperatures, with the potential to enable significant improvements in efficiency and emission reduction in aerospace and power generation. ...

Researchers have discovered that light -- from a laser -- can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons 'spins,' which have a potential applications in quantum computing. Scientists discovered that electrons within the...

Scientists have grown thin films of two different crystalline materials on top of each other using an innovative technique called 'dative epitaxy.' The researchers discovered the method by surprise. As a physicist explains, dative epitaxy holds layers of different materials together via a weak...

The early universe may chirp about unknown physics. A research team has demonstrated how an early universe phase transition will lead to gravitational wave signals potentially visible in the upcoming satellite missions. ...
