Small but mighty: TESSERACT joins the hunt for dark matter

For decades, people have been trying to directly detect dark matter: the missing mass in our universe. Now, there's a new, super-sensitive detector on the caseā€”and even though it's still in the research and development ...

A dark energy driven by star formation

Rolf Landauer showed that "information is physical" with every bit equivalent to a small amount of energy proportional to temperature. The Landauer equivalent energy of information carried, or represented by matter, effectively ...

Distinguishing classical from quantum gravity through measurable stochastic fluctuations

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature.

Airborne microplastics: Where do they come from, where do they go?

How tiny plastic particles enter the atmosphere is an important question, as airborne microplastics are a potential health threat. Using a global chemical transport model, researchers have provided evidence that, contrary ...

Einstein's light quanta through the lens of Maxwell's equations

Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves are generated under specific interactions. Light also bends around corners, resulting in fringing ...
