The energy that plants capture from sunlight through photosynthesis provides the source of nearly all of humanity's food. Yet the process of photosynthesis has inefficiencies that limit crop productivity, especially in a ...

Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ...

The perception of a chemist varies. Some might imagine the "mad scientist" from old cartoons—a white-haired older man working with beakers in his lab—but as that cliche fades, the reality of what constitutes a chemist's ...

The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting ...

Researchers at the University of Jyväskylä have discovered a simple way to program synthetic molecules so they can form specific spiral-like structures by embedding instructions directly into their sequence. This breakthrough ...

In a new study published in Nature, scientists have successfully developed genetically modified mosquitoes in Tanzania that block the transmission of malaria. The team includes researchers from the Ifakara Health Institute ...

In 2020, as scientists around the world were racing to understand COVID-19, Prof. Roy Bar-Ziv and his team at the Weizmann Institute of Science started developing a DNA chip that could not only quickly show how our immune ...

Wood warblers, also called New World warblers, are some of the most colorful birds in North America, with more than a hundred species in the family ranging in color from yellow, orange and red to blue, green and pink. A new ...

Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen cycling. Yet, despite their ubiquity, scientists have long puzzled over how these microbes can flourish ...

Around the world, phytoplankton in the upper ocean help to cycle key nutrients and regulate Earth's climate by absorbing carbon dioxide. These photosynthesizing organisms rely on dissolved iron as an essential micronutrient, ...

From small ions to large molecules, cellular gates control what can pass in and out of cells. But how one such gate, called pannexin-1 (PANX1), can handle vastly different cargo sizes has remained a long-standing mystery.

There is a dire need for selective catalysts that allow us to consistently achieve a desired outcome in a chemical reaction. It is this consistency that allows for more efficient, energy-saving ways of producing fuel. A team ...
