Who are we? Why are we here? We are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic molecules, researchers investigated the role of low-energy electrons created as cosmic radiation traverses through ice particles. Their findings may also inform medical and

Although climate change may bring increased precipitation to many parts of the United States, some areas may face drier conditions and lower streamflow, resulting in decreased hydropower generation. In a new study assessing how climate change might alter hydropower generation across the continental United States, researchers show that except for some parts of the Southwest

Physicists have developed a new model that describes how filaments assemble into active foams. LMU physicists have developed a new model that describes how filaments assemble into active foams. Many fundamental processes of life, and their synthetic counterparts in nanotechnology, are based on the autonomous assembly of individual particles into complex patterns. LMU physicist Professor

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath

Electron transfer is enhanced by minimal energetic driving force at the organic-semiconductor interface in upconversion (UC) organic light emitting diodes (OLEDs), resulting in efficient blue UC-OLEDs with low extremely turn-on voltage, scientists show. Their findings deepen the understanding of electron transfer mechanisms in organic optoelectronic devices and can lead to the development of efficient new

Our understanding of Venus' water history and the potential that it was once habitable in the past is being challenged by recent observations. Thanks to observations by the Solar Occultation in the Infrared (SOIR) instrument on the Venus Express space probe of the European Space Agency (ESA), researchers have discovered an unexpected increase in the

Heat waves, droughts, and fires place growing stress on the West's electric grid. New research suggests that more integrated management of electricity resources across the region could significantly reduce the risk of power outages and accelerate the transition to clean energy. This summer's Western heat waves raise the specter of recent years' rotating power outages

James Joyce's tome 'Finnegans Wake' famously breaks the rules of normal prose through its unusual, dreamlike stream of consciousness, and new work in chaos theory takes a closer look at how Joyce's challenging novel stands out mathematically. Researchers compared the distribution of punctuation marks in various experimental novels to determine the underlying order of 'Finnegans

Engineering researchers have successfully developed a quantum microprocessor chip for molecular spectroscopy simulation of actual large-structured and complex molecules. Quantum simulation enables scientists to simulate and study complex systems that are challenging or even impossible using classical computers across various fields, including financial modelling, cybersecurity, pharmaceutical discoveries, AI and machine learning. For instance, exploring molecular

A new adaptive 3D printing system can identify the positions of randomly distributed organisms and safely move them to specific locations for assembly. A first-of-its-kind adaptive 3D printing system developed by University of Minnesota Twin Cities researchers can identify the positions of randomly distributed organisms and safely move them to specific locations for assembly. This

Scientists have developed photoresponsive supramolecular polymers that can undergo both intrachain folding and interchain aggregation. The material properties of polymers are determined by the competition between polymer chain folding and aggregation. For the first time, researchers from Japan developed folded supramolecular polymers that can spontaneously undergo interchain aggregation. Using atomic force microscopy, they revealed that

Researchers develop a one pot process to transform aromatic ketones to esters, offering advancements in pharmaceutical synthesis and materials science. Aromatic ketones have traditionally been underutilized in cross-coupling reactions due to the difficulty in breaking their tough C-C bonds. Researchers have now introduced a novel method that overcomes this challenge by transforming aromatic ketones into
