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 ...
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 ...
Phys.org / Discovery of a possible pulsar in the Milky Way's center could enable unprecedented tests of General Relativity
Researchers from Columbia University and Breakthrough Listen, a scientific research program aimed at finding evidence of civilizations beyond Earth, have published new results from the Breakthrough Listen Galactic Center ...
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 / DNA-binding proteins from volcanic lakes could improve disease diagnosis
Scientists have uncovered new DNA-binding proteins from some of the most extreme environments on Earth and shown that they can improve rapid medical tests for infectious diseases. The work has been published in Nucleic Acids ...
Phys.org / What to watch as fungal infections rise: Species that can quickly 'translate' fat-use proteins
A new study by researchers at Kiel University and MPI-EvolBio describes how more efficient protein production drives the adaptation of fungi to the human body, potentially turning previously harmless species into emerging ...
Medical Xpress / Australia's food labeling system isn't working—here's how we can fix it
If you've ever read a food label and come away feeling more confused, you're not alone. Since 2014, Australian shoppers have relied on the Health Star Rating scheme to help them choose which foods to eat. This system ranks ...
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 / 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 / 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 ...
Tech Xplore / Building batteries that don't break in the cold
Extreme winter weather can strain power systems, stall electric vehicles and leave backup batteries unable to deliver energy when it is most needed. Researchers at Texas A&M University have now developed a battery design ...
