The "15-minute city" might not be realistic for North America, researchers find
In the "15-minute city," a concept popularized in Europe, everything a resident might need on a daily basis is a short walk or bicycle ride away. A study by Transportation Research at McGill University (TRAM) suggests, however, that this model may no.....»»
Novel catalysts for improved methanol production using carbon dioxide dehydrogenation
Encapsulating copper nanoparticles within hydrophobic porous silicate crystals has been shown by scientists at Tokyo Tech to significantly enhance the catalytic activity of copper-zinc oxide catalysts used in methanol synthesis via CO2 hydrogenation......»»
Focusing micromechanical polaritons in topologically nontrivial hyperbolic metasurfaces
Dr. Johan Christensen, leader of IMDEA Materials Institute's Mechanical and Acoustic Metamaterials research group, is among the researchers behind a pioneering study exploring the topological properties of metamaterials......»»
Human activity: A double-edged sword in the face of drought
Earth and environmental scientists have reported that, as human socio-economic activities increase, greenhouse gas emissions will rise, leading to more frequent extreme weather events such as droughts and floods. However, a research team from Pohang.....»»
Many more bacteria produce greenhouse gases than previously thought, study finds
Caltech researchers have discovered a new class of enzymes that enable a myriad of bacteria to "breathe" nitrate when in low-oxygen conditions. While this is an evolutionary advantage for bacterial survival, the process produces the greenhouse gas ni.....»»
Unlocking the entrepreneurial brain: New perspectives on cognitive flexibility
In a recent study led by the University of Liège researchers delved into the intersection of the fields of entrepreneurship and neuroscience, looking specifically at the cognitive flexibility of habitual entrepreneurs—those who repeatedly launch n.....»»
Exploring the roots of the Anthropocene
Understanding how tropical land use and deforestation affects the dynamics of the global Earth system and identifying potential tipping points are key to the future of our species on this planet. By exploring the long history of human societies in tr.....»»
Key mechanism in nuclear reaction dynamics promises advances in nuclear physics
Researchers have made significant progress in understanding the transfer of neutrons in weakly bound nuclei. The experiment, performed at Legnaro National Laboratory, focused on the one-neutron stripping process in reactions involving lithium-6 and b.....»»
Biophysicists decipher functionality of adrenaline-binding receptor
G protein-coupled receptors (GPCRs) are found throughout the human body and are involved in many complex signaling pathways. Despite their importance in many biological processes, the central mechanism of G protein-coupling and the associated signal.....»»
Inspired by nature: Synthetic nightshade molecule effective against leukemia cells
Nightshade plants produce a diverse array of compounds with therapeutic potential. Researchers at CeMM have now identified an artificial variant inspired by the Withanolides group that acts highly specifically against leukemia cells......»»
Scientists solve the puzzle of directional hearing underwater
When underwater, humans cannot determine where a sound comes from. Sound travels about five times faster there than on land. That makes directional hearing, or sound localization, nearly impossible because the human brain determines the origin of a s.....»»
Science Is Full of Errors. Bounty Hunters Are Here to Find Them
A new project is paying researchers to find errors in other scientists’ work. The only problem? Even error hunters make mistakes......»»
Dietary sucrose determines activity of lithium on gene expression and lifespan in D. melanogaster
The amount of dietary sugars and the administration of lithium both impact the lifespan of the fruit fly Drosophila melanogaster. It is noteworthy that lithium is attributed with insulin-like activity as it stimulates protein kinase B/Akt and suppres.....»»
New research focuses on use of cactus pear in biofuel production
As much of the world prepares for hotter and drier growing seasons as the result of climate change, a research team led by University of Nevada, Reno researchers has identified several varieties of cactus pear that are particularly well-suited to pro.....»»
Researchers release first national study on partner-friendly support for dual-career academic jobseekers
In the first national study analyzing the support of academic couples, researchers at the University of North Carolina at Chapel Hill have developed a full ranking of universities by their partner-friendly status and resources for dual-career academi.....»»
Scientists use heart and lung model to calculate potential health threats facing future space tourists in microgravity
Space exploration has always captivated our imagination, offering the promise of discovering new worlds and pushing the boundaries of human capability. As commercial space travel becomes more accessible, individuals with various underlying health con.....»»
An efficient protein delivery system with spider minor ampullate silk protein nanoparticles
In a study published in the journal MedComm, researchers have developed an efficient protein delivery carrier based on spider silk proteins (spidroins), derived from Araneus ventricosus minor ampullate silk protein (MiSp). The MiSp-based nanoparticle.....»»
Sunlight and plastic: A risky combination for bottled water safety
Plastic water bottles are ubiquitous due to their convenience, yet they harbor potential risks. Sunlight exposure can lead these containers to degrade and emit volatile organic compounds (VOCs), which are potentially detrimental to human health. The.....»»
Researchers describe how to tell if ChatGPT is confabulating
Finding out whether the AI is uncertain about facts or phrasing is the key. Enlarge (credit: Aurich Lawson | Getty Images) It's one of the world's worst-kept secrets that large language models give blatantly false answer.....»»
Behavioral and computational study shows that social preferences can be inferred from decision speed alone
Researchers led by Sophie Bavard at the University of Hamburg, Germany, found that people can infer hidden social preferences by observing how fast others make social decisions......»»
