Phys.org / Bird guano powered rise of Chincha Kingdom in Peruvian Andes, archaeologists find
New archaeological evidence reveals that seabird guano—nutrient-rich bird droppings—was not only essential to boosting corn yields and supercharging agriculture in ancient Peru, but it may have been a driving force behind ...
Medical Xpress / HPV cancer vaccine slows tumor growth and extends survival in preclinical model
Throughout the past decade, Northwestern University scientists have uncovered a striking principle of vaccine design: Performance depends not only on vaccine components but also on vaccine structure. After proving this concept ...
Phys.org / Predicting an animal's immune response based on its genetic data
What if cattle were selected not only for their productivity, but also for their resistance to disease? A study conducted by a team of scientists combining systemic immunology, genomics and machine learning provides a better ...
Phys.org / Strike against mask wearing in 1930s echoed COVID-19 protests, study finds
New research from The University of Manchester has shown that debates and resistance about wearing face masks go back a lot further than the COVID-19 pandemic. Dr. Meng Zhang, a Wellcome Trust Research Fellow at the University's ...
Tech Xplore / What chatbots can teach humans about empathy
Over half of U.S. adults are using large language models (LLMs)—such as ChatGPT, Gemini and Copilot—in some capacity. Whether using artificial intelligence to create grocery lists, turn oneself into a Muppets character ...
Phys.org / Twilight fish study reveals unique hybrid eye cells
Researchers have identified a new type of visual cell in deep-sea fish larvae that challenges a century of knowledge about vertebrate visual systems. Dr. Fabio Cortesi from The University of Queensland's School of the Environment ...
Phys.org / Supercomputer simulations test turbulence theories at record 35 trillion grid points
Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence ...
Medical Xpress / 'Dancing molecules' paralysis treatment heals lab-grown human spinal cord organoids
Northwestern University scientists have developed the most advanced organoid model for human spinal cord injury to date. In a new study, the research team used lab-grown human spinal cord organoids—miniature organs derived ...
Phys.org / Bison hunters abandoned long-used site 1,100 years ago to adapt to changing climate, Great Plains study finds
On the Great Plains of North America, bison were hunted for thousands of years before populations collapsed to near extinction due to overexploitation in the late 1800s. But long before then, bison hunters used various strategies ...
Medical Xpress / A hidden neuron 'gatekeeper' may shape Alzheimer's buildup of amyloid-beta
Brain cells are constantly swallowing material from the fluid that surrounds them—signaling molecules, nutrients, even pieces of their own surfaces—in a process known as endocytosis that is essential for learning, memory ...
Phys.org / Quantum dots reveal entropy production, a key measure of nanoscale energy dissipation
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these technologies involve ...
Phys.org / A new way to 'cage' plutonium
Plutonium (Pu) exhibits one of the most diverse and complex chemistries of any element in the periodic table. Since its discovery in 1940, scientists have synthesized and studied many different types of plutonium-containing ...
