Phys.org / Ancient stellar flyby may still be steering long-period comets today
The Gaia mission has allowed researchers to understand the motions of stars like never before, even revealing possible interactions between our solar system and nearby stars. Planetary Science Institute Senior Scientist Nathan ...
Phys.org / Why old nuclear-site concrete could become a tool for trapping strontium-90
Crushed concrete from legacy nuclear facilities could play a far greater role in safely managing radioactive land than previously understood. Research published in ACS ES&T Water and conducted by scientists from the University ...
Phys.org / Ultra-fast light-shaping technology could be 'game-changer' for future imaging
Scientists have developed a new type of "virtual" metasurface—capable of controlling light in ways traditional lenses and optics can't—which they say is superior to the current approach, which relies on ultrathin engineered ...
Phys.org / Commute stress can fuel workplace conflict, but research suggests a simple fix
Pothole season, summer construction season or maybe bad weather. No matter the time of year, it's no surprise commuters who drive to work may start their day already feeling a bit on edge.
Phys.org / Centuries-old planktonic shell mystery solved with discovery of self-assembling proteins
Biomaterials with extraordinary properties, such as spider silk, have so far been known primarily from animals. Researchers at the University of Salzburg in Austria have now deciphered a surprising counterpart from the world ...
Phys.org / Natural hallucinogens may have evolved as ecological tools, not chemical accidents
Natural hallucinogens, such as psilocybin, mescaline, N,N-dimethyltryptamine (DMT) and related compounds, have generally received attention for their effects on human perception, emotion and cognition. Recently, interest ...
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 ...
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 / 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 / Inorganic nanoscale device behaves like a single neuron, opening doors for AI and retinal implants
McGill University researchers have developed a light-detecting nanoscale structure that mimics how a neuron processes information. The neuron-like behavior emerges from the materials themselves, reducing the energy demand ...
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 ...
