As the world shifts toward sustainable energy sources, "green hydrogen"—hydrogen produced without emitting carbon—has emerged as a leading candidate for clean power. In a significant step forward, a research team has developed a new iron-based catalyst that more than doubles the conversion efficiency of thermochemical green hydrogen production.

A small team of planetary scientists, astrophysicists and space flight researchers affiliated with several institutions in the U.S. and one in France has made the first direct detection of atmospheric sputtering on Mars.

Cohesin is a protein that forms a ring-shaped complex which wraps and alters the DNA molecule shape. It moves through the DNA and creates specific loops in the genetic material which determine the architecture of the genome and gene expression.

Cannabis has been a globally important crop for millennia. While best known today as marijuana for its psychoactive cannabinoid THC (tetrahydrocannabinol), historically, cannabis has been a cornerstone of human civilization, providing seed oil, textiles, and food for more than 10,000 years. Today, cannabis remains an understudied and underutilized resource, but United States legislation passed in 2014 and 2018 have re-energized cannabis crop development for medicinal, grain, and fiber applications.

Nanomedicines, especially those based on nanoparticles, are revolutionizing health care in terms of both diagnostics and therapeutics. These particles, often containing metals like iron or gold, can serve as contrast agents in medical imaging, act as nutritional supplements, and even function as carriers for drug delivery.

Imagine cells navigating through a complex maze, guided by chemical signals and the physical landscape of their environment. A team of researchers at the University of Maryland, Baltimore County (UMBC) has contributed to an important discovery about how cells move, or migrate, through this maze of bodily tissues, using the fruit fly egg chamber as a model system. Potential implications include better understanding of diseases like cancer and advancing medical treatments.

Long considered a disease brought to the Americas by European colonizers, leprosy may actually have a much older history on the American continent.

Sensing environmental temperature is crucial for the development and survival of animals. Insects such as fruit flies have evolved a particularly delicate thermosensory system that can discriminate temperature changes within a milli-degree per second.

A research team led by Prof. Kang Yanbiao from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has developed a supercapacitor (SC)-assisted electrophotocatalysis for the efficient defluorination of the polytetrafluoroethylene (PTFE) and poly- and perfluoroalkyl substances (PFAS) at low temperatures.

A research team led by Associate Prof. Wang Anting from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) proposed a method for multidimensional manipulation of polarization and phase based on a single geometric phase element. They managed to generate and control high-order vector vortex beams (VVBs).
