Tech Xplore / Six criteria for the reliability of AI
Language models based on artificial intelligence (AI) can answer any question, but not always correctly. It would be helpful for users to know how reliable an AI system is. A team at Ruhr University Bochum and TU Dortmund ...
Phys.org / Ancient hominin fossils reveal two human ancestors lived side by side
With the help of newly identified bones, an enigmatic 3.4-million-year-old hominin foot found in 2009, is assigned to a species different from that of the famous fossil Lucy providing further proof that two ancient species ...
Phys.org / Uncovering a new genetic code in archaea opens doors for bioengineering applications
The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in which one or two additional ...
Medical Xpress / Data-driven surgical supply lists can reduce hospital costs and waste
Researchers at University of California San Diego School of Medicine, in collaboration with Data Science Alliance, a nonprofit promoting the importance of a responsible science environment, led a study showing that hospitals ...
Medical Xpress / Dual mechanisms drive rapid eye dominance plasticity in the adult brain, study reveals
Studies have shown that even a few hours of monocular deprivation can markedly improve the visual function of the deprived eye in adults. However, the underlying neural mechanisms of this ocular dominance plasticity remain ...
Medical Xpress / How a mitochondrial mutation rewires immune function
Scientists have discovered how a mitochondrial mutation rewires immune function in a model of inherited primary mitochondrial disorders, which often lead to severe disability and death. They have discovered that this single ...
Phys.org / The collapse of Maya civilization: Drought doesn't explain everything
Between 750 and 900 CE, the population of the Maya lowlands in Central America experienced a major demographic and political decline which, according to the scientific literature, coincided with repeated episodes of intense ...
Medical Xpress / How the brain decides what to remember: Study reveals sequentially operating molecular 'timers'
Every day, our brains transform quick impressions, flashes of inspiration, and painful moments into enduring memories that underpin our sense of self and inform how we navigate the world. But how does the brain decide which ...
Phys.org / Old air samples hint at effects of climate change
Through DNA analysis of old air samples collected by the Swedish Armed Forces, researchers at Lund University in Sweden can show that spore dispersal of northern mosses has shifted over the past 35 years. It now starts several ...
Medical Xpress / Parkinson's drug tolcapone found to block key protein in hospital superbug
When the hospital germ Pseudomonas aeruginosa infects the body, it uses the sugar-binding protein LecA to attach itself to human cells, invade them, and form so-called biofilms. LecA thus plays a central role in the development ...
Phys.org / What meadows reveal about the future: Spatial data can predict biodiversity loss before species disappear
Meadows once teeming with buzzing insects and colorful plants are quietly losing their diversity. But how fast is this change happening and can we detect it before species disappear? A German-Swiss research team led by Professor ...
Phys.org / From inhibition to destruction: Kinase drugs found to trigger protein degradation
Protein kinases are the molecular switches of the cell. They control growth, division, communication, and survival by attaching phosphate groups to other proteins. When these switches are stuck in the "on" position, they ...
