Artificial electron donors and acceptors expand researchers’ metabolic engineering options — if only cells would cooperate.

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the interactions between atoms are governed by the valence electrons, their findings shine light on the fundamental nature of chemical bonds, with implications for pharmacy and chemical engineering. The results were published in the Journal of the American Chemical Society.

Dr. Scott England: “As the aurora intensifies, you see more lights, but along with that, there’s more energy entering the atmosphere, so it makes the atmosphere near the poles very hot, which starts to push air away from the poles and towards the equator.”

How do powerful geomagnetic storms from the Sun influence the Earth’s atmosphere? This is what two separate studies (Karan et al. (2024) and Evans et al. (2024)) published in Geophysical Research Letters hopes to address as a team of researchers investigated how the geomagnetic storm that occurred between May 10–12, 2024—resulting in worldwide aurorae—impacted the Earth’s thermosphere, which is the Earth’s upper atmosphere extending approximately 70 miles to 130 miles above the Earth’s surface. This study holds the potential to help researchers better understand the short-and long-term effects of geomagnetic storms on the Earth’s atmosphere and how this could influence activities on the surface.

“The northern lights are caused by energetic, charged particles hitting our upper atmosphere, which are impacted by numerous factors in space, including the sun,” said Dr. Scott England, who is an associate professor in the Kevin T. Crofton Department of Aerospace and Ocean Engineering at Virginia Tech and a co-author on both studies. “During solar geomagnetic storms, there’s a lot more of these energetic charged particles in the space around Earth, so we see a brightening of the northern lights and the region over which you can see them spreads out to include places like the lower 48 states that usually don’t see this display.”

A view into how nanoscale building blocks can rearrange into different organized structures on command is now possible with an approach that combines an electron microscope, a small sample holder with microscopic channels, and computer simulations, according to a new study by researchers at the University of Michigan and Indiana University.

The approach could eventually enable smart materials and coatings that can switch between different optical, mechanical and electronic properties.

Cities around the globe are experiencing increased flooding due to the compounding effects of stronger storms in a warming climate and urban growth. New research from the University of California, Irvine suggests that urban form, specifically the building density and street network of a neighborhood, is also affecting the intensity of flooding.

For a paper published today in Nature Communications, researchers in UC Irvine’s Department of Civil and Environmental Engineering turned to statistical mechanics to generate a new formula allowing urban planners to more easily assess flood risks presented by land development changes.

Co-author Mohammad Javad Abdolhosseini Qomi, UC Irvine associate professor of civil and environmental engineering who holds a joint appointment in UC Irvine’s Department of Materials Science and Engineering, said that he and his colleagues were inspired by how physicists study intricate systems such as disordered porous solids, glasses and complex fluids to develop universal theories that can explain city-to-city variations in flood hazards.

🎵🎶…Mars ain’t the kind of place to raise your kids…🎵🎶 Even then, since Mars has 38% of Earth’s gravity, it can only retain an atmosphere of about 0.38 bar.

These are some of the most compelling ideas on how to terraform Mars into a habitable, Earth-like world for future explorers.

Researchers have demonstrated a technique for printing thin metal oxide films at room temperature, and have used the technique to create transparent, flexible circuits that are both robust and able to function at high temperatures.

The paper, “Ambient Printing of Native Oxides for Ultrathin Transparent Flexible Circuit Boards,” was published August 15 in the journal Science.

Vast amounts of water found on Mars, but there’s a catch, Milky Way and Andromeda might not merge after all, a planet found before it gets destroyed, and an easier way to terraform Mars.

A research team at Rice University led by James Tour, the T.T. and W.F. Chao Professor of Chemistry and professor of materials science and nanoengineering, is tackling the environmental issue of efficiently recycling lithium ion batteries amid their increasing use.

The team has pioneered a new method to extract purified active materials from battery waste as detailed in the journal Nature Communications on July 24. Their findings have the potential to facilitate the effective separation and recycling of valuable battery materials at a minimal fee, contributing to a greener production of electric vehicles (EVs).

“With the surge in battery use, particularly in EVs, the need for developing sustainable recycling methods is pressing,” Tour said.
