Phys.org / Ancient asteroid barrage may explain why early Earth had no stable continents
New research led by Curtin University and QUT (Queensland University of Technology) has revealed that repeated asteroid impacts may have been the dominant force shaping early Earth, delivering vast amounts of heat into the ...
Phys.org / Warming may slow forest growth and cut carbon storage by 30%, model shows
Forests and land play an important role in absorbing carbon dioxide emissions, but current models and forecasts don't incorporate a surprising ecological discovery: Despite more available carbon, climate change and warmer ...
Medical Xpress / Hope for spinal injuries as pigs walk again after experimental gel treatment for severed spinal cords
In humans and other mammals, spinal cord injuries can be devastating, leading to permanent loss of movement, sensation and bladder control. When severed axons (the long fibers that carry messages between nerve cells) cannot ...
Phys.org / How ancient subduction zones helped create hotspots of mineral wealth
A study led by geoscientists at the University of Sydney has revealed why some ancient continental edges became fertile sites for major mineral deposits, while others with apparently similar geology did not.
Phys.org / Scientists measure hidden quantum forces that could power a new generation of pharmaceutical drugs
It's one thing to design a pharmaceutical drug. It's another to know if and why it actually works; not on paper or in a computer model, but inside the chaotic world of living systems, where proteins twist into shape, atoms ...
Phys.org / What really controls water chemistry in nanoscale spaces
Water is the most studied molecule on Earth, yet a surprisingly basic question has gone unanswered for decades: When water is squeezed into gaps just a few molecules wide—as happens inside nanoscale pores, membranes and biological ...
Medical Xpress / First potential probiotic treatment for lupus identified by researchers
Scientists at UT Health San Antonio, the academic health center of The University of Texas at San Antonio, have found a link between a bacterium in the gut microbiome (ecosystem) and lupus that could lead to more effective ...
Phys.org / Microscale hydrogel fibers could enable imaging inside tiny tissue structures
Researchers have developed light-transmitting hydrogel fibers that are just hundreds of micrometers in diameter. With further development, these soft fibers could one day make it possible to use imaging techniques to detect ...
Phys.org / Seven exotic quantum phases predicted in ultracold magnetic atoms, including topological superconductivity
Strongly interacting quantum particles are key to some of the most fascinating phenomena in modern physics—from magnetism and superconductivity to topological states. Yet the complexity of such systems makes many of their ...
Science X / AI in the classroom: Are we building better thinkers or better shortcuts?
AI chatbots like ChatGPT have made their way into college life, sparking an important debate: Do these tools actually help students become better thinkers, or are they just a shortcut? Universities want to foster critical ...
Medical Xpress / Iron accumulation in the brain may contribute to neurodegeneration
Neurodegenerative diseases affect tens of millions of people worldwide. Among these, Alzheimer's and Parkinson's diseases are the most common; in the United States alone, the Alzheimer's Disease Association and Parkinson's ...
Phys.org / Laser pulses capture unexplored polaronic states
In an international experiment, researchers observed Jahn–Teller polarons—quasiparticles that could play an important role in future ultrafast spintronic devices. These polarons emerged within the crystal lattice of cobalt ...
