Researchers identify new drivers of antibiotic resistance in bacteria
Two newly discovered mechanisms in bacteria have been identified that can contribute to the development of antibiotic resistance. Changing the number of copies of resistance genes in bacteria increases antibiotic resistance, and can do so very quickl.....»»
Researchers develop deep-learning model that outperforms Google AI system to predict peptide structures
Researchers at the University of Toronto have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides—chains of amino acids that are shorter than proteins, but perform similar biological functions......»»
Uranium science researchers investigate feasibility of intentional nuclear forensics
Despite strong regulations and robust international safeguards, authorities routinely interdict nuclear materials outside of regulatory control. Researchers at the Department of Energy's Oak Ridge National Laboratory are exploring a new method that w.....»»
Study projects loss of brown macroalgae and seagrasses with global environmental change
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role of seaweeds and seagrasses in coastal ecosystems, and.....»»
What can social media tell us about public views on climate change?
IIASA researchers contributed to a new study, analyzing the main narratives in public discussions of climate change on social media. The research is published in the journal Current Research in Environmental Sustainability......»»
Young voters have growing power, but broken politics leave them "fatalistic," studies find
Young voters from the millennial generation and Gen Z are emerging as the demographic center of power in American politics, but new studies by UC Berkeley researchers find they are fatalistic about critical problems such as economic inequality, clima.....»»
Fifty-three experts weigh in on the global methane budget
Accurate estimates of atmospheric greenhouse gas levels are needed to understand and address the drivers of climate change. Of particular interest is atmospheric methane, which has increased in concentration by 160% since preindustrial times and acco.....»»
Aging Might Not Be Inevitable
There are biological underpinnings to aging—and so researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets......»»
Newly-discovered bacterial regulatory mechanism has implications for antibacterial control measures
Research spearheaded by four biologists within the College of Arts and Sciences at Indiana University Bloomington has uncovered a new regulatory mechanism shared by many bacteria, which may have profound implications for anti-bacterial control measur.....»»
Scientists develop the next generation of highly efficient memory materials with atom-level control
Like the flutter of a butterfly's wings, sometimes small and minute changes can lead to big and unexpected results and changes in our lives. A team of researchers at Pohang University of Science and Technology (POSTECH) has made a very small change t.....»»
Exciting applications for marine degradable, bio- and CO2-based PISOX polymers
Researchers at the Industrial Sustainable Chemistry (ISC) group at the Van 't Hoff Institute for Molecular Sciences have developed a new class of bio- and CO2 based PISOX polymers with surprising properties and applications......»»
Key mechanism of herpesvirus egress uncovered, offering new target for antiviral therapies
An international team of researchers, led by the Leibniz Institute of Virology (LIV), have uncovered crucial details on how herpesviruses exit the cell nucleus without compromising the integrity of the nuclear envelope. Herpesvirus infections are wid.....»»
Researchers create green solvent to boost lignin applications
Lignin, the glue that holds fibers together in trees and plants, is one of the most common yet one of the most complex biocomposites, because there are so many variants and qualities. Its heterogeneous chemical structure makes it difficult to investi.....»»
Visual explanations of machine learning models to estimate charge states in quantum dots
A group of researchers has successfully demonstrated automatic charge state recognition in quantum dot devices using machine learning techniques, representing a significant step toward automating the preparation and tuning of quantum bits (qubits) fo.....»»
"Power rivalry in space": China lunar mission fuels US misinformation
A historic lunar mission has demonstrated China's growing scientific prowess, but the feat has set off a torrent of misinformation targeting the United States that researchers say reflects their bitter competition in space......»»
Luxe cars stolen via thief"s texts to drivers
A 2024 Mercedes-Maybach GLS 600 and 2022 Rolls-Royce Cullinan worth a combined $620,000 were stolen in Florida via texts changing delivery drivers' instructions......»»
Researchers just solved AI’s biggest conundrum
That's roughly the draw of a 100W light bulb, and a 50x improvement over the 700W that an NVIDIA H100 GPU consumes......»»
Researchers find genetic stability in a long-term Panamanian hybrid zone of manakins
We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stabl.....»»
Researchers built AI models that use less power than a light bulb
That's roughly the draw of a 100W light bulb, and a 50x improvement over the 700W that an NVIDIA H100 GPU consumes......»»
