Phys.org / Crystal-design principle reveals how competing molecular forces control structure, color and phase transitions
Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular ...
Phys.org / Black-box optimization weather intervention method supports future disaster mitigation
In recent years, the frequency of weather-related natural disasters—cyclones, torrential rains, floods—has increased as a consequence of global warming. These disasters cause billions of dollars in damage and losses every ...
Phys.org / Can AI plan for heat emergencies better than simple rules? It depends
The thermometer reads 95°F (35°C) in Brooklyn, and vulnerable individuals need information to take appropriate action. New York City officials must gather facts quickly to provide updates on cooling centers, power outages ...
Phys.org / Polymer network reconfigures in sequence, helping elastomers stay tough under strain
Shock-absorbing sneaker soles are likely made of polyurethane, a highly elastic and tough polymer. The ability of these elastomers to absorb impact without breaking is extremely important for practical applications. While ...
Phys.org / 3,000-year-old Irish Bronze Age site may be one of Europe's earliest 'town-like' settlements
A major prehistoric center in Ireland was among the first large, organized settlements to develop in Western Europe more than 3,000 years ago, new research reveals. The study, published today in Antiquity, identifies Haughey's ...
Phys.org / An iconic spear-throwing device likely wasn't used by prehistoric hunters until around 10,000 years ago
Archaeologists have long pictured prehistoric hunters taking down mammoths and other megafauna using the atlatl, a handheld spear-throwing device that uses leverage to achieve greater velocity and force when throwing darts. ...
Phys.org / One of the most distant 'leaky' galaxies ever found may reveal how the universe reionized
Astronomers have identified one of the most distant candidate galaxies known to leak ionizing radiation—the same kind of radiation thought to have transformed the early universe during the epoch of reionization.
Phys.org / Open cluster NGC 6134 in Norma is 1.38 billion years old and hosts a core, tidal tail and diffuse halo
Indonesian astronomers have conducted a comprehensive study of an open cluster in the constellation Norma, known as NGC 6134. Results of the new study, available in a research paper published June 23 on the preprint server ...
Phys.org / Nearby 'Super Earth' may be a better candidate for life than previously thought
Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits ...
Phys.org / Abundant catalyst converts methane into valuable liquid chemicals
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and their collaborators have demonstrated a promising new approach for converting methane—the primary component of natural gas—into liquid ...
Phys.org / Scientists teach human cells to compute like tiny computers
Researchers have developed a way to program human cells to perform calculations and make autonomous decisions, similar to how computer chips work.
Phys.org / Astronomers find an enigmatic source that is most likely a Little Red Dot in formation
Astronomers have, for the first time, found a source in the process of becoming a Little Red Dot, using the James Webb Space Telescope (JWST). Little Red Dots are likely early galaxies and some of the most intriguing objects ...
