Researchers solve structure of 'inverted' rhodopsin

Researchers from the Moscow Institute of Physics and Technology, working with Spanish, French and German colleagues, have determined and analyzed the high-resolution structure of a protein from the recently discovered heliorhodopsin ...

Turning cells into computers with protein logic gates

The same basic tools that allow computers to function are now being used to control life at the molecular level. The advances have implications for future medicines and synthetic biology.

A new way to fine-tune exotic materials: Thin, stretch and clamp

One way to change the properties of a material is to stretch it just a wee bit, so its atoms are farther apart but the bonds between them don't break. This extra distance affects the behavior of electrons, which determine ...

Does relativity lie at the source of quantum exoticism?

Since its beginnings, quantum mechanics hasn't ceased to amaze us with its peculiarity, so difficult to understand. Why does one particle seem to pass through two slits simultaneously? Why, instead of specific predictions, ...

Study finds no media bias when it comes to story selection

For as long as there have been news media, there have been allegations that journalists are biased and slant stories to fit their views. While many studies have explored this issue, there has been little research into how ...

Technique reveals how crystals form on surfaces

The process of crystallization, in which atoms or molecules line up in orderly arrays like soldiers in formation, is the basis for many of the materials that define modern life, including the silicon in microchips and solar ...

Researchers forecast longer, more extreme wildfire seasons

In California, a changing climate has made autumn feel more like summer, with hotter, drier weather that increases the risk of longer, more dangerous wildfire seasons, according to a new Stanford-led study.

COVID-19: How satellites can help

The coronavirus COVID-19 pandemic has virtually paralyzed daily life as we know it. Even when the spread of this highly infectious disease has been stemmed, the world will face huge challenges getting back to normal. To help ...

Satellites map the global flow of oil

Demand for oil has collapsed due to the coronavirus pandemic just as supply is about to strengthen because of a dispute between Russia and Saudi Arabia. As a result, oil prices have sunk to levels not seen since 2002.

Most people consider becoming vegetarian for their health

Researchers know that people are motivated to be vegetarian for different reasons—the most common in western cultures being health, the environment and animal rights. But how compelling are these different factors for nonvegetarians?

Decrypting cryptocurrencies

Cryptocurrencies have been treated as a financial terra incognita—they have enjoyed growing interest but also raised concerns due to their virtuality. The use of statistical methods utilizing correlation matrices to analyze ...

Extracellular forces help epithelial cells stick together
