Medical Xpress / Why you hardly notice your blind spot: New tests pit three theories of consciousness
Although humans' visual perception of the world appears complete, our eyes contain a visual blind spot where the optic nerve connects to the retina. Scientists are still uncertain whether the brain fully compensates for the ...
Tech Xplore / How can you rescue a 'kidnapped' robot? New AI system helps robots regain their sense of location
Mobile robots must continuously estimate their position to navigate autonomously. However, satellite-based navigation systems are not always reliable: signals may degrade near buildings or become unavailable indoors. To operate ...
Phys.org / Northern Europe's radiator: Volcanic eruptions in the past may have pushed ocean currents toward collapse
New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning Circulation (AMOC), causing temperatures ...
Medical Xpress / Macrophages need constant reminders to retain memories of prior infections, researchers discover
Researchers from the University of California, Los Angeles, have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind ...
Phys.org / Beyond 'survival' of fittest: Evolution works in teams
Survival of the fittest. Nature red in tooth and claw. The common view of natural selection is based solely on the individual: A trait allows an organism to out-compete its rivals and is thus passed down to its offspring. ...
Medical Xpress / AI for language access in surgical care: Patient preferences and an implementation framework
Language barriers contribute substantially to inequities in U.S. surgical care. Spanish-speaking patients are especially affected by communication challenges and inconsistent interpreter access during complex or time-sensitive ...
Phys.org / Replacing humans with machines is leaving truckloads of food stranded and unusable
Supermarket shelves can look full despite the food systems underneath them being under strain. Fruit may be stacked neatly, chilled meat may be in place. It appears that supply chains are functioning well. But appearances ...
Phys.org / Satellite imagery and AI reveal development needs hidden by national data
For years, Iceland, Switzerland, and Norway have ranked near the top of the United Nations' annual index of countries based on indicators of well-being and quality of life. Countries with more poverty and less access to health ...
Medical Xpress / Big data and human height: Scientists develop algorithm to boost biobank data retrieval and analysis
Extracting and analyzing relevant medical information from large-scale databases such as biobanks poses considerable challenges. To exploit such "big data," attempts have focused on large sampling algorithms that model individual ...
Medical Xpress / Evidence suggests chatbot disclaimers may backfire, strengthening emotional bonds
Concerns that chatbot use can cause mental and physical harm have prompted policies that require AI chatbots to deliver regular or constant reminders that they are not human. In an opinion appearing in Trends in Cognitive ...
Medical Xpress / Cannabis: What is the profile of adults at low risk of dependence?
A new study led by Marie-Pierre Sylvestre, professor at the Université de Montréal School of Public Health, examines cannabis use four to five years after Canadian legalization by adopting a different perspective: Rather ...
Phys.org / If alien signals have already reached Earth, why haven't we seen them?
For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically ...
