Medical Xpress / AI brain scan model identifies stroke, brain tumors and aneurysms
A new AI model could help radiologists identify brain abnormalities in MRI scans for all conditions including stroke, multiple sclerosis and brain tumors.
Phys.org / Simulations reveal how black holes generate intense light from infalling matter
Surprisingly, some of the universe's brightest objects are black holes. As scorching gas and dust flow around and into a black hole, they glow with fierce intensity across the light spectrum. Now, a team of computational ...
Phys.org / Lemon shark caught preying on invasive freshwater fish in Fernando de Noronha, Brazil
Researchers recorded lemon sharks (Negaprion brevirostris) preying on an invasive species, the jaguar cichlid (Parachromis managuensis), for the first time. This observation was made in Sueste Bay in March 2024. Sueste Bay ...
Medical Xpress / Specialized neuron populations in the mouse cortex coordinate to guide correct decisions, study suggests
For decades, neuroscientists have been trying to pinpoint the neural underpinnings of behavior and decision-making. Past studies suggest that specialized groups of neurons in the mammalian brain, particularly in the cortex, ...
Phys.org / Rice enzyme OsPLC4 triggers Ca²⁺ and ROS bursts to drive ferroptotic cell death in immune response
A research team at Sejong University's Plant Immunity Laboratory, led by Professor Nam-Soo Jwa, has uncovered an important regulatory component of rice immunity.
Medical Xpress / Saliva and plasma at the core of cancer detection and treatment
Saliva and plasma could be crucial in detecting recurrences or relapses of head and neck cancers, negating the need for a painful and invasive biopsy.
Phys.org / Fullerenes could improve MRI clarity by enabling more efficient dynamic nuclear polarization
Magnetic resonance imaging (MRI) is invaluable in the medical world. But despite all the good it does, there is room for improvement. One way to enhance the sensitivity of MRI is dynamic nuclear polarization (DNP), where ...
Medical Xpress / Family dogs boost adolescent mental health through the microbiome, study suggests
It's no surprise that dogs benefit people's mental health. In a paper published in iScience, researchers point to a reason as to why: dogs prompt changes in the collection of microbes that live in and on our bodies, resulting ...
Tech Xplore / Meta partners with news outlets to expand AI content
Meta announced Friday it will integrate content from major news organizations into its artificial intelligence assistant to provide Facebook, Instagram and WhatsApp users with real-time information.
Phys.org / Long-standing puzzle in electron scattering deepens with new measurement
Why does lead behave so differently from every other atomic nucleus when struck by electrons? A team of physicists at Johannes Gutenberg University Mainz (JGU) has taken an important step toward answering this question, only ...
Phys.org / Precise catalyst design boosts hydrogen gas production efficiency and affordability
A recent advance in the science of hydrogen fuel production could enable higher output and more sustainable production of this renewable energy source, researchers with Stockholm's KTH Royal Institute of Technology report.
Phys.org / From static papers to living models: Turning limb development research into interactive science
The choreographed movements that cells perform to form complex biological shapes, like our hands, have fascinated scientists for centuries. Now, researchers at EMBL Barcelona have launched LimbNET, an open-access online platform ...
