New open-source software predicts energy transfer between tiny defects in solid materials‎

The performance of many next-generation devices depends on controlling how energy flows at extremely small scales. In the field of microelectronics—where devices continue to shrink and new materials are introduced—small imperfections in solids can strongly influence how a material stores, transfers or loses energy. Those processes can either be used to improve device performance or create problems such as energy loss, information loss, signal disruption or reduced reliability.

Modified cell vesicles trigger 'lipid counterstorm' against lung inflammation in mice‎

The COVID-19 pandemic highlighted severe consequences of unchecked respiratory disease, including cytokine storms. This phenomenon affected many COVID-19 patients and is a potential side effect of many other diseases involving significant inflammation, but approaches to treating these symptoms remain unclear.

Diego Rivera claimed his mural Creation was half wax, but chemical forensics says otherwise‎

Adorning the walls of San Ildefonso College in Mexico City is artist Diego Rivera's masterpiece, rendered in fresco and gold leaf, The Creation, or La Creacioń. It depicts a man standing with his arms outstretched beneath a deep blue celestial disk studded with stars and constellations, while figures seated on clouds watch from either side. The work catalyzed the revival of the encaustic painting technique in the 1920s.

New low-water method could make production of clean-energy materials much greener‎

A new Concordia study has demonstrated a greener way to produce an important class of catalytic materials with promising potential for cleaner energy technologies that rely more on acoustic energy than water and chemicals. The work is published in the journal Advanced Synthesis & Catalysis.

Magnetic nanoparticles remove forever chemicals from water‎

PFAS, otherwise known as forever chemicals, have become commonplace in numerous everyday and industrial products. At the same time, they are some of the most problematic pollutants of our times: They are extremely durable, accumulate in the environment and in organisms and can only be removed from water with difficulty.

French, Italian winegrowers face earliest ever harvest‎

Scorching summer temperatures have disrupted life for millions of Europeans, but for winegrowers in Italy and France who are harvesting their grapes unusually early, the hot weather offers pros as well as cons.

Ancient Irish volcano offers new clues about the development of its modern-day, active 'brothers and sisters'‎

An international team of volcanologists working on Carlingford Mountain has found that liquid "magma chambers" do not always exist beneath volcanoes. The team instead demonstrated that magma "plumbing systems" beneath Earth's surface can fluctuate between solid- and liquid-dominated states, providing an improved view of how active volcanoes evolve through time.

Agricultural waste could fuel protein-rich black soldier fly larvae for human foods‎

They're wriggly black grubs more commonly tossed to backyard hens than served at the dinner table, but black soldier fly larvae could soon play a key role in building a more sustainable food system, according to new research from Adelaide University.

Only 1 in 3 people arrested by ICE have a criminal conviction, research reveals‎

Just 34% of people arrested by the U.S. Immigration and Customs Enforcement agents during President Donald Trump's second term have a criminal conviction, according to research published in the Proceedings of the National Academy of Sciences. That's a near-historic low, the authors note.
