Tech Xplore / Laughter reveals how we use AI at home
Voice assistants such as Alexa are often marketed as smart tools that streamline everyday life. But once the technology moves into people's homes, interest quickly fades. This is shown by new research in which laughter is ...
Phys.org / Prehistoric fossil poses puzzles in shark research
A newly examined prehistoric shark from the age of dinosaurs provides surprising insights into the early evolution of modern sharks. It cannot be confidently assigned to any shark order that exists today and thus calls into ...
Phys.org / Why do people living at high altitudes have better glucose control? The answer was in plain sight
In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels—such as those found at high altitudes. One of the most striking observations from that ...
Phys.org / Gotland hunter-gatherer graves hint at how Stone Age families organized
A woman was buried with two children, but they were not her own. In another grave, two children were placed. They were not siblings and were more distantly related, perhaps cousins. In a new study published in the Proceedings ...
Tech Xplore / Safer railroads through ultrasound: Beamforming algorithms can improve track safety inspections
Advances in ultrasound—the same imaging technology that uses sound waves to allow doctors to monitor babies in utero—are being applied by engineers at the University of California San Diego to make railroad track inspection ...
Phys.org / A yeast enzyme helps human cells overcome mitochondrial defects
Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most animal cells, this process depends closely on properly functioning mitochondria, the organelles ...
Phys.org / NASA boss blasts Boeing and space agency managers for Starliner's botched astronaut flight
NASA's new boss blasted Boeing and the space agency Thursday for Starliner's botched flight that left two astronauts stuck for months at the International Space Station.
Phys.org / Physicists explain the exceptional energy-harvesting efficiency of perovskites
Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar ...
Phys.org / Offshore wind farms change ocean current patterns, simulations show
By 2050, offshore wind power capacity in the North Sea is set to increase more than tenfold. Researchers at the Helmholtz Center Hereon have analyzed the long-term overall impact of this large number of wind farms on the ...
Medical Xpress / Therapeutic outcomes for autistic adults: Exploring factors that shape anxiety and depression trajectories
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by differences in social interactions and in the understanding of others' thoughts or feelings, restricted interests and repetitive behaviors. ASD can ...
Phys.org / Preservation through technology: 3D modeling of a historic building from 15th century
Led by Dr. Marco Funari, the project focused on developing a 3D model of a Grade I listed historic site, providing an accurate representation of the building's current condition to support effective management and preservation. ...
Medical Xpress / How dopamine-producing neurons arise in the developing brain
In a new study from Karolinska Institutet, published in Nature Neuroscience, researchers have identified the neurogenic progenitor that gives rise to dopaminergic neurons, the primary neurons affected in Parkinson's disease. ...
