Phys.org / Stretching metals can tune catalysis: A new method predicts energy shifts
Heterogeneous catalysis—in which catalysts and reactants are of different phases, e.g., solid and gas—is important to many industrial processes and often involves solid metal as the catalyst. Ammonia synthesis, catalytic ...
Phys.org / Free software lets laptops simulate how aging evolves under selection
Why do some species live for only weeks while others survive for centuries? Researchers at the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena have developed AEGIS, a freely available software tool that enables ...
Phys.org / New microporous aerogel uses van der Waals forces for flexible, moldable shaping
Porous materials are widely used for gas storage, separation, catalysis, and environmental purification. Their functionality arises from nanoscale pores that allow molecules to be selectively captured or transported. However, ...
Phys.org / Accuracy test for protein language models shines light into AI 'black box'
AI language models, used to generate human-like text to power chatbots and create content, are also revolutionizing biology by treating complex biological data like a language. Language models are increasingly used, for example, ...
Phys.org / Reducing aircraft soot might not actually reduce the climate effects of contrails
Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails from aircraft contribute ...
Phys.org / Precision work prior to cell division: How enzymes optimize DNA structure
Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the DNA is wrapped around ...
Phys.org / Atomic-level simulations reveal rotational mechanism behind a critical biomolecular motor
The way a key cellular motor works at an atomic level has been uncovered by simulations conducted by RIKEN biophysicists. This finding, published in the journal Proceedings of the National Academy of Sciences, provides important ...
Phys.org / Can you trust a finding? A new project maps which studies replicate
Findings from the Systematizing Confidence in Open Research and Evidence (SCORE) program—a collaborative effort involving 865 researchers—have been published in Nature as a collection of three papers alongside a release of ...
Phys.org / A new way to detect breakthroughs in science: Large-scale analysis reveals 'disruptive' innovations in research history
The history of science and technology is marked by major breakthroughs—the theory of evolution, the splitting of the atom, the development of antibiotics—and a research team including faculty at Binghamton University, State ...
Phys.org / Ghost bat dialects emerge across colonies, study suggests
Accents are usually thought of as a human trait, indicating where a person has grown up or the communities they belong—and new research shows the same dialects can also occur in Australia's largest carnivorous bat.
Phys.org / Saturn's magnetic bubble is lopsided compared to Earth's, suggests new study
Saturn's magnetic shield is asymmetrical compared to Earth's, suggests a new study involving University College London (UCL) researchers, and this is likely a result of its fast rotation coupled with the heavy material it ...
Phys.org / One of cholera's great enemies is found in the human gut
Cholera-causing bacteria are locked in an evolutionary arms race with a viral nemesis, according to a new genomic study. Researchers have found that, in the Ganges Delta, cholera bacteria rapidly gain and lose special armor ...
