On Average, Average May Not Mean What You Think It Does

The different kinds of averages and what they’re good for.

Have we detected dark energy? Scientists say it's a possibility

Dark energy, the mysterious force that causes the universe to accelerate, may have been responsible for unexpected results from the XENON1T experiment, deep below Italy's Apennine Mountains.

Have we detected dark energy? Scientists say it's a possibility

A new study, led by researchers at the University of Cambridge and reported in the journal Physical Review D, suggests that some unexplained results from the XENON1T experiment in Italy may have been caused by dark energy, and not the dark matter the experiment was designed to detect.

How Indirect DNA Transfer Is Challenging Forensics and Overturning Wrongful Convictions

Prosecutors and forensic researchers say DNA evidence is not so cut and dry.

Cylindrical phononic crystals sense physical, chemical properties of transported liquids

Phononic crystals are an innovative resonant platform for sensing and understanding the volumetric properties of liquids, attracting a growing interest from researchers.

Light does the twist for quantum computing

Scientists have generated circularly polarized light and controlled its direction without using clunky magnets or very low temperatures. The findings show promise for the development of materials and device methods that can be used in optical quantum information processing.

Algorithm finds personalized sound zones in cars for driver, passengers

Creating an individualized listening experience for each passenger has been an ambition for the auto industry for decades. The acoustically changing nature of the car cabin has hampered making such personalized sound zones (PSZs) a reality.

A unique material with tunable properties is explored in a new study

Researchers use mass spectroscopy and ultrafast laser pulses to interrogate chromium oxides in unprecedented detail.

Taking lessons from a sea slug, study points to better hardware for artificial intelligence

The sea slug has taught neuroscientists the most basic intelligence features that any creature in the animal kingdom needs to survive. Now, researchers have mimicked these strategies in a quantum material, a step toward figuring out how to build artificial intelligence directly into hardware.

Just by changing its shape, scientists show they can alter material properties

Scientists have observed that when the shape of a thin film of metal oxide known as titania is confined at the mesoscale, its conductivity increases. This finding demonstrates that nanoscale confinement is a way to control quantum effects.
