Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries, where they are helping to reduce reliance on electricity generated from fossil fuels. While most solar cells used today ...

Mobile phones today handle far more wireless signals and services than earlier generations. The same is true of the sophisticated equipment behind mobile networks, such as base stations, and emerging technologies such as ...

Sustainable business practices are often seen as a luxury that only rich countries can afford. And these days, some of the biggest economies, including the U.S., are backtracking on those commitments.

There are few pleasures greater than letting a piece of chocolate melt slowly on your tongue. Indeed, the proximity of chocolate's melting point to our own body temperature is one reason it is so widely appreciated.

Researchers have found a way to speed up components that control light polarization in optical communication and computing. Polarization is a property of light that can carry additional information along with the primary ...

Inspired by the cracked, water-trapping skin of elephants, Penn researchers have developed a low-cost cement tile that cools buildings by capturing and slowly evaporating water—turning a structural flaw into a climate solution.

Controlling interactions between molecules and their functions from the molecular level to the macroscopic scale is challenging in supramolecular and materials chemistry. To this end, a research team led by associate professor ...

Researchers have developed a new type of optical fiber by freezing a glass capillary filled with liquid. It guides light and sound waves simultaneously and enables highly efficient coupling between them. The high coupling ...

Researchers from Skoltech, in collaboration with the Harbin Institute of Technology and Jiangsu University (China), have published a study presenting the first empirical model to explain and predict the sensing behavior of ...

From headlines and social media, psychedelic therapies, cannabis use and GLP-1 medications have seemingly become commonplace overnight, but the science underlying these treatments and the pathway to drug approval are often ...

Developing thermoelectric materials that efficiently convert waste heat into electricity remains challenging because high electrical performance and low thermal conductivity are difficult to achieve simultaneously. Researchers ...

Long before dinosaurs ruled the continents and modern crocodiles first appeared, their ancestors were already going through a decisive phase in their evolutionary history. It was in this ancient world, shortly after the greatest ...
