Phys.org / Earth system models overstate carbon removal: New findings suggest nitrogen fixation is 50% lower than thought
High levels of atmospheric carbon dioxide intensify climate change, but high carbon dioxide levels can also stimulate plant growth. Plant growth removes carbon dioxide from the atmosphere, partially mitigating the effects ...
Phys.org / When substrates dictate the route: Deuterium source reshapes hydrogen isotope exchange pathways
A collaboration between the groups of Professor Mónica H. Pérez-Temprano at the Institute of Chemical Research of Catalonia (ICIQ) and Professor Anat Milo at Ben-Gurion University of the Negev has uncovered how the characteristics ...
Phys.org / Earthquakes shake up Yellowstone's subterranean ecosystems
Up to 30% of life, by weight, is underground. Seismic activity may renew the energy supply for subterranean ecosystems. Published in PNAS Nexus, Eric Boyd and colleagues chronicled the ecological changes in subsurface microbial ...
Tech Xplore / New model measures how AI sycophancy affects chatbot accuracy and rationality
If you've spent any time with ChatGPT or another AI chatbot, you've probably noticed they are intensely, almost overbearingly, agreeable. They apologize, flatter and constantly change their "opinions" to fit yours.
Medical Xpress / Why the 'gut brain' plays a central role for allergies
An international research team led by scientists from Bern and Charité—Universitätsmedizin Berlin has identified a previously unknown function of the intestinal nervous system.
Medical Xpress / Scientists develop one-product-fits-all immunotherapy for pancreatic cancer
Pancreatic cancer is among the deadliest forms of cancer, with most patients diagnosed after the disease has already spread throughout the body. The five-year survival rate for metastatic cases hovers around 2–3%, and median ...
Phys.org / Growing human organs for medical implants: New method gives human stem cells an edge in chimeric embryos
Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants.
Phys.org / Anomalous electronic state opens pathway to room-temperature superconductivity
Superconductive materials can conduct electricity with no resistance, but typically only at very low temperatures. Realizing superconductivity at room temperature could enable advanced, energy-efficient electronics and other ...
Tech Xplore / Strategic maintenance could double Öresund Bridge lifespan to 200 years
Researchers at Lund University have developed a new framework that can lead to the Öresund Link, thanks to the right maintenance at the right time and smart monitoring, having a total lifespan of 200 years. This is twice ...
Medical Xpress / Metabolic roots of memory loss: Early obesity and low choline levels linked to brain inflammation risk
For decades, scientists have known that what harms the body often harms the brain. Conditions such as obesity, high blood pressure and insulin resistance strain the body's vascular and metabolic systems. Over time, that stress ...
Tech Xplore / LLMs use grammar shortcuts that undermine reasoning, creating reliability risks
Large language models (LLMs) sometimes learn the wrong lessons, according to an MIT study. Rather than answering a query based on domain knowledge, an LLM could respond by leveraging grammatical patterns it learned during ...
Medical Xpress / Collaborating minds think alike, processing information in similar ways in a shared task, study shows
Whether great minds think alike is up for debate, but the collaborating minds of two people working on a shared task process information alike, according to a study published in PLOS Biology by Denise Moerel and colleagues ...
